Hydraulic Cylinder Producing Process

Step1: Quality Control on Raw Material
We have our own lab in factory, inspect the raw material and do the test. For every batch of material we received, we will ask supplier provide their certificate, and then cut them to do the test again to see if the results match the certification. Also, every batch we received, we will cut them into pieces to check the air bubbles. Once they are all qualified, we will accept it, and all detail information will be recording in our ERP system. We will also pay lot of attention on the salt spray test for chrome rod. Every month, we will cut the material, put them into test machine to see if it reach the requirement. All the result will be recorded at our QC department. If customer need, we can provide it.

Step2: Quality Control on Machining

we start doing components machining from 1988 with 36 years experience now and insist doing 100% inspection. We spend lots of money, invest on auto robots and machines. Now half of the producing line is by robot so that we can ensure our quality be stable good. For every part of the cylinder, we do 3 times inspecting. Firstly, workers will do self inspection. Secondly, we have tour-hour inspection checking the products, 2 times in the morning and 2 times in the afternoon, make sure that every step is good. After the products are all completed, we will do 100% inspection. For thread, for the tolerance, everything, we need double check. Also, we have specific warehouse just for the measuring tools. Every inspector have their own measuring tool and we will check the measuring tools regularly to make sure they are all in good condition, so that the measuring results will be convincing.

Step3: Quality Control on Welding

We are qualified to AWS certification, which is very popular in North American market. First, for the visual test, we will make sure that every components are welded good, look beautiful. And the second, we need to check the penetration. We have more than 15 years experience, we do know what kind of designing angle can make the cylinder welding strong. Once we finish the first article, we will cut it and analyse the welding to see if it is fulfill the groove. And then do the radiographic testing to make sure there is no gap inside. What’s more, we will do the ultrasonic test to check the program for the robot. Now 80% of welding is doing by robot. Once the program confirmed, no 1 can change it unless the welding manager, and they only have 5% right.

Step4: Quality Control on Assembling
For assembling, we have some difference with others. The brand we uses for seals are all those famous brand like Aston, Parker, Hallite. The cylinder we give to our customer has 2 years warranty. For our company, we engrave our part number and manufacturing date for the quality warranty. So no matter for seals or any others, as long as they are parts of cylinder, if it is under 2 years, we will take responsibility for them. And we will do the test for every cylinder like for pressure after we finish assembling.

Step5: Quality Control on Painting
We have our half auto painting line. Right now, we can paint about 1500 cylinders per day, which is about 1 container. Before we do the painting, we will do the wash first and for every cylinder, we will test for hardness, thickness and adhesion to make sure the painting are all good, which will be recorded into OQC report, print out and stick on the box, ship to you with your products.

Step6: Hydraulic Cylinder Packing
For every cylinder, we have the stick to show the detail information like bore size, stroke and working pressure. And we will use individual plastic bag packing. If customer need, we can also use individual carton box packing. We will fasten 1 floor after 1 floor with plat, so customer can only cut what they need and other layer will still be fasten. Moreover, there will be plywood pallet or plywood box for customer choosing. We will also send the loading picture to customer after we ship them to make sure everything is well loaded in China.

Can telescopic cylinders be used in construction equipment like cranes?

Yes, telescopic cylinders are commonly used in construction equipment, including cranes. Here’s a detailed explanation:

Role in crane operation:

Telescopic cylinders play a critical role in the operation of cranes by enabling the extension and retraction of crane booms or arms. The telescopic cylinder is typically located at the base of the boom and is responsible for extending or retracting the boom sections, allowing the crane to reach different heights and distances.

Extension and retraction mechanism:

The telescopic cylinder in a crane consists of multiple stages or sleeves that retract inside one another. This nested design allows for compact storage when the boom is retracted, minimizing the overall length of the crane. When the cylinder extends, the stages slide out, increasing the length of the boom and providing the necessary reach. The synchronized extension and retraction of the stages are facilitated by the hydraulic control system.

Hydraulic control system:

The hydraulic control system in cranes is responsible for the precise and controlled extension and retraction of telescopic cylinders. It regulates the flow of hydraulic fluid to each stage of the cylinder, ensuring synchronized movement. By adjusting the flow rate, the operator can control the speed of extension and retraction, allowing for smooth and controlled operation of the crane.

Load handling capabilities:

Telescopic cylinders in cranes are designed to handle significant loads. They provide the necessary lifting force to support heavy loads at various boom lengths. The cylinder’s bore size, rod diameter, and overall construction are engineered to withstand the forces exerted during lifting and to deliver the required lifting capacities.

Variety of crane types:

Telescopic cylinders are utilized in various types of cranes, including mobile cranes, truck-mounted cranes, and crawler cranes. These cranes are widely used in construction sites, infrastructure projects, and other lifting and material handling applications. The versatility of telescopic cylinders allows them to be integrated into different crane designs and configurations.

Advantages of telescopic cylinders in cranes:

Telescopic cylinders offer several advantages in crane applications. These include:

  • Compactness: Telescopic cylinders enable the boom to be retracted to a compact size, making it easier to transport and maneuver the crane in confined spaces.
  • Reach and height capabilities: The telescopic design allows the crane to achieve extended reach and height, enabling it to access elevated work areas or reach over obstacles.
  • Efficiency: The controlled extension and retraction of telescopic cylinders contribute to efficient operation, allowing the crane to adjust its boom length quickly and precisely.
  • Stability: Telescopic cylinders provide stability to the crane by supporting the boom and load, ensuring safe lifting and lowering of heavy objects.

Overall, telescopic cylinders are integral components of construction equipment like cranes. They enable the extension and retraction of crane booms, contribute to efficient and controlled operation, and enhance the lifting capabilities of cranes in various construction and material handling tasks.

It’s important to consult the crane manufacturer’s documentation and guidelines for specific information on the telescopic cylinder’s capabilities, maintenance requirements, and safety considerations.

How do telescopic cylinders handle variations in hydraulic pressure and flow rate?

Telescopic cylinders are designed to handle variations in hydraulic pressure and flow rate effectively. Here’s a detailed explanation:

Hydraulic pressure control:

Telescopic cylinders are equipped with hydraulic systems that allow for precise control of hydraulic pressure. The hydraulic pressure is regulated by a pump that supplies pressurized hydraulic fluid to the cylinder. The pressure can be adjusted according to the specific requirements of the application.

Pressure relief valves:

To handle variations in hydraulic pressure, telescopic cylinders often incorporate pressure relief valves. These valves are designed to limit the maximum pressure within the cylinder to prevent damage or failure. When the pressure exceeds the set limit, the relief valve opens, allowing excess fluid to bypass and relieve the pressure. This ensures the safety and integrity of the telescopic cylinder and the hydraulic system.

Flow control:

Telescopic cylinders also handle variations in flow rate through the hydraulic control system. The flow rate of hydraulic fluid into and out of the cylinder determines the speed of extension and retraction. Flow control valves, such as flow restrictors or flow control valves, are commonly employed to regulate the flow rate.

Flow restrictors:

Flow restrictors are used to limit the flow rate of hydraulic fluid entering or leaving the telescopic cylinder. By restricting the flow, the speed of extension or retraction can be controlled. This allows for precise and gradual movement, preventing abrupt or uncontrolled motion.

Flow control valves:

Flow control valves are designed to provide adjustable flow rates by regulating the opening or closing of hydraulic passages. These valves allow operators to control the speed of extension and retraction of the telescopic cylinder. By adjusting the flow control valves, variations in flow rate can be accommodated to suit specific operational requirements.

Sequencing valves:

In some applications, telescopic cylinders may require a specific sequence of extension and retraction. Sequencing valves are used to control the order in which different stages of the telescopic cylinder extend or retract. These valves ensure proper synchronization of the cylinder stages and prevent uneven or unbalanced movement.

Overall, telescopic cylinders employ various hydraulic components and control mechanisms to handle variations in hydraulic pressure and flow rate. Pressure relief valves protect against excessive pressure, flow restrictors and flow control valves regulate the flow rate, and sequencing valves ensure proper sequencing of cylinder stages. These features allow telescopic cylinders to operate safely, precisely, and efficiently under different hydraulic conditions.

It’s important to consult the manufacturer’s documentation and guidelines for specific information on the hydraulic system and control mechanisms of telescopic cylinders, as well as recommended maintenance and safety practices.

How does a telescopic cylinder differ from standard hydraulic cylinders?

A telescopic cylinder differs from standard hydraulic cylinders in several ways. Here’s a detailed explanation:

A telescopic cylinder, also known as a multistage cylinder or a sleeve cylinder, is specifically designed to provide an extended stroke length while maintaining a compact retracted length. In contrast, a standard hydraulic cylinder typically consists of a single-stage rod and barrel design. Here are the key differences between a telescopic cylinder and a standard hydraulic cylinder:

  • Design and Structure: The most significant difference lies in the design and structure. A standard hydraulic cylinder has a single-stage design, meaning it consists of a single rod and barrel. On the other hand, a telescopic cylinder features multiple stages or sleeves nested inside one another. This nested structure allows for a longer stroke length while keeping the retracted length compact.
  • Stroke Length: The stroke length of a telescopic cylinder can be significantly longer compared to a standard hydraulic cylinder. The ability to extend in multiple stages allows for a greater overall stroke length, making telescopic cylinders suitable for applications that require extended reach or height adjustment.
  • Retracted Length: While a standard hydraulic cylinder has a fixed retracted length equal to its stroke length, a telescopic cylinder offers a compact retracted length. The nested design enables the stages to retract inside one another, reducing the overall length of the cylinder when not in use. This compact retracted length is advantageous in applications with space constraints.
  • Load Capacity: Telescopic cylinders are designed to handle substantial loads while maintaining stability. The nested structure provides increased load-bearing capacity compared to standard hydraulic cylinders. The stages distribute the load evenly, ensuring efficient load transfer throughout the extended stroke.
  • Complexity and Maintenance: Telescopic cylinders are generally more complex in design compared to standard hydraulic cylinders. They require precise alignment of the stages and may include additional components such as locking mechanisms or guiding systems. This complexity can affect maintenance requirements and may require specialized inspection and servicing procedures.
  • Application: Telescopic cylinders are commonly used in applications that require extended reach or height adjustment, such as cranes, dump trucks, aerial platforms, and material handling equipment. Standard hydraulic cylinders, on the other hand, are versatile and widely used in various applications, including industrial machinery, construction equipment, and agricultural machinery.

Despite these differences, both telescopic cylinders and standard hydraulic cylinders are essential components in hydraulic systems. They both rely on hydraulic fluid to generate force and provide linear motion. The selection of the cylinder type depends on the specific requirements of the application, including stroke length, retracted length, load capacity, and available space.

It’s important to consult the manufacturer’s guidelines and specifications to ensure the proper selection, installation, and maintenance of the hydraulic cylinder based on the specific application requirements.

What is a telescopic cylinder and how does it work?

A telescopic cylinder is a type of hydraulic cylinder that consists of multiple nested stages or sections that can extend and retract, similar to a telescope. Here’s a detailed explanation:

A telescopic cylinder is primarily used when a long stroke length is required while maintaining a compact retracted length. It is commonly used in applications such as dump trucks, cranes, aerial platforms, and other equipment that require extended reach or height adjustment. Here’s how a telescopic cylinder works:

  • Structure: A telescopic cylinder consists of a series of cylindrical stages or sleeves that are progressively nested inside one another. These stages are typically made of high-strength steel or aluminum alloy. The number of stages can vary depending on the specific design and application.
  • Extension and Retraction: When the telescopic cylinder is in the retracted position, the stages are nested inside one another, with the smallest stage located at the base. To extend the cylinder, hydraulic fluid is supplied to the base of the cylinder, creating pressure that pushes the smallest stage outwards. As the smallest stage extends, it exposes the next larger stage, which is then pushed out by the hydraulic pressure. This process continues until all the stages have extended, resulting in a longer overall stroke length.
  • Locking Mechanism: Telescopic cylinders often incorporate a locking mechanism to secure the extended stages in position. This mechanism ensures stability and prevents unintentional retraction of the cylinder under load. The locking mechanism can be mechanical, hydraulic, or a combination of both, depending on the design and application requirements.
  • Retraction: To retract the telescopic cylinder, hydraulic fluid is supplied to the opposite side of the cylinder, typically to the largest stage. The hydraulic pressure acts on the largest stage, retracting it first. As each stage retracts, it nests inside the next smaller stage until the cylinder is fully retracted to its original compact length.
  • Control and Stability: The extension and retraction of a telescopic cylinder are controlled by a hydraulic system. By regulating the flow and pressure of the hydraulic fluid, operators can precisely control the extension and retraction speed of the cylinder. The nested design of the stages provides stability and load-bearing capacity, allowing the telescopic cylinder to handle substantial loads.

The use of telescopic cylinders offers several benefits:

  • Extended Stroke Length: Telescopic cylinders provide a significantly longer stroke length compared to traditional single-stage cylinders, enabling extended reach or height adjustment without increasing the overall size of the cylinder.
  • Compact Design: The nested structure of telescopic cylinders allows for a compact retracted length, making them suitable for applications with space constraints.
  • Versatility: Telescopic cylinders can be customized to meet specific stroke length requirements. The number of stages can be adjusted, and the cylinders can be designed for different load capacities and working conditions.
  • Efficient Operation: The controlled extension and retraction of telescopic cylinders enable precise load handling and positioning, improving operational efficiency.

Overall, a telescopic cylinder is a hydraulic cylinder with nested stages that can extend and retract, providing an extended stroke length while maintaining a compact retracted length. Its structure and operation make it ideal for applications requiring long reach or height adjustment.

It’s important to follow the manufacturer’s guidelines and specifications for the telescopic cylinder, including proper maintenance and inspection, to ensure its safe and reliable operation.
