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.

How does a double-acting hydraulic cylinder handle variations in cylinder stroke and extension?

A double-acting hydraulic cylinder is designed to handle variations in cylinder stroke and extension effectively. Here’s a detailed explanation:

1. Bidirectional Operation: One of the key advantages of a double-acting hydraulic cylinder is its ability to generate force in both the extending and retracting strokes. This bidirectional operation allows the cylinder to handle variations in stroke and extension. Whether the cylinder needs to extend or retract, hydraulic fluid can be supplied to the appropriate side of the cylinder, enabling the desired movement. This flexibility in operation allows for easy adjustment to accommodate different stroke lengths and extension requirements.

2. Adjustable Stroke Length: Double-acting hydraulic cylinders often feature adjustable stroke lengths. The stroke length refers to the distance the piston can travel within the cylinder. By adjusting the position of the end stops or limit switches, the stroke length of the cylinder can be modified to match specific application requirements. This adjustability enables the cylinder to handle variations in stroke length and extension, allowing for precise positioning and the accommodation of different workpiece sizes or operational needs.

3. Control of Hydraulic Fluid Flow: The flow rate and pressure of the hydraulic fluid can be controlled to manage variations in cylinder stroke and extension. By adjusting the flow control valves and regulating the hydraulic pressure, operators can achieve the desired speed and force during cylinder operation. This control over fluid flow allows for smooth and controlled movement, compensating for any variations in stroke length or extension requirements.

4. Position Sensing and Feedback: Double-acting hydraulic cylinders often incorporate position sensing devices or feedback mechanisms. These sensors can detect the position of the piston within the cylinder and provide feedback to the control system. By monitoring the position feedback, operators can ensure accurate and consistent stroke lengths and extensions. This feedback loop helps to maintain precise control over the cylinder’s movement, compensating for any variations and ensuring reliable performance.

5. Robust Construction and Tolerance Compensation: Double-acting hydraulic cylinders are built with robust construction and designed to handle variations in stroke and extension. They are typically manufactured with close tolerances to minimize internal leakage and ensure efficient operation. Additionally, the seals and piston rings used in the cylinder are designed to accommodate minor variations and provide a reliable and consistent seal, compensating for any tolerance differences and maintaining the integrity of the hydraulic system.

Through bidirectional operation, adjustable stroke length, control of hydraulic fluid flow, position sensing and feedback, as well as robust construction and tolerance compensation, double-acting hydraulic cylinders effectively handle variations in cylinder stroke and extension. These features make them versatile and adaptable components in various industries, including manufacturing, construction, and automation.

How does a double-acting hydraulic cylinder handle variations in hydraulic pressure?

A double-acting hydraulic cylinder is designed to handle variations in hydraulic pressure while maintaining its functionality and performance. Here’s a detailed explanation:

1. Balanced Design: Double-acting hydraulic cylinders are designed with a balanced piston and rod arrangement. This design ensures that the hydraulic pressure acts equally on both sides of the piston, allowing for consistent and balanced force generation. As a result, the cylinder can handle variations in hydraulic pressure without compromising its ability to extend and retract smoothly.

2. Efficient Sealing System: Double-acting cylinders incorporate a sealing system that helps maintain the integrity of the hydraulic fluid and prevents leakage. The piston and rod seals, typically made of materials like rubber or polyurethane, create a tight seal between the piston and the cylinder barrel. This sealing system ensures that hydraulic pressure is effectively contained within the cylinder, reducing the impact of pressure variations on the cylinder’s performance.

3. Pressure Relief Mechanism: In situations where there are significant variations in hydraulic pressure, double-acting hydraulic cylinders may incorporate a pressure relief mechanism. This mechanism allows excess pressure to be released from the cylinder, preventing damage to the seals and other internal components. Pressure relief valves or adjustable relief valves are commonly used to regulate the pressure within the cylinder and protect it from excessive pressure fluctuations.

4. Robust Construction: Double-acting hydraulic cylinders are constructed using high-strength materials such as steel or aluminum. This robust construction enables the cylinder to withstand variations in hydraulic pressure without deformations or failures. The materials used, along with proper engineering and manufacturing techniques, ensure the structural integrity of the cylinder even under challenging pressure conditions.

5. Performance Testing and Quality Control: Manufacturers of double-acting hydraulic cylinders subject their products to rigorous performance testing and quality control measures. These tests evaluate the cylinder’s ability to handle variations in hydraulic pressure, ensuring that it meets the required performance and safety standards. Through these quality control processes, any potential issues related to pressure variations are identified and addressed before the cylinder is deployed.

By employing a balanced design, efficient sealing system, pressure relief mechanisms, robust construction, and thorough quality control, double-acting hydraulic cylinders can effectively handle variations in hydraulic pressure.
