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.

double acting hydraulic cylinder

How does a double-acting hydraulic cylinder contribute to energy-efficient force generation?

A double-acting hydraulic cylinder plays a significant role in energy-efficient force generation. Here’s a detailed explanation:

1. Bi-Directional Operation: One of the key features of a double-acting hydraulic cylinder is its ability to generate force in both directions. This bi-directional operation allows for efficient energy utilization. When pressurized hydraulic fluid is supplied to one side of the cylinder, the piston extends, generating force in one direction. Conversely, when the fluid is supplied to the other side, the piston retracts, producing force in the opposite direction. By utilizing both extension and retraction strokes, the hydraulic cylinder maximizes force output while minimizing energy consumption.

2. Conservation of Potential Energy: A double-acting hydraulic cylinder has the ability to conserve and utilize potential energy effectively. During the extension stroke, the cylinder stores potential energy in the compressed hydraulic fluid. This stored energy can be released during the retraction stroke, minimizing the need for additional energy input. By harnessing and reusing this potential energy, the hydraulic cylinder contributes to energy efficiency, reducing the overall energy requirements for force generation.

3. Load Counterbalancing: In certain applications, a double-acting hydraulic cylinder can be used for load counterbalancing, further enhancing energy efficiency. Load counterbalancing involves using the hydraulic cylinder to oppose and balance external loads, reducing the overall energy required to move or hold the load. By strategically applying hydraulic pressure to the appropriate side of the cylinder, the system can counterbalance the load’s weight, minimizing energy consumption and improving efficiency.

4. Flow Control and Regeneration: Double-acting hydraulic cylinders can incorporate flow control and regeneration mechanisms to optimize energy efficiency. Flow control valves can be used to regulate the flow rate of hydraulic fluid, ensuring that the force generation matches the required load and speed. Regeneration valves or circuits allow the hydraulic fluid to be redirected during the cylinder’s retraction stroke, bypassing the pump and reducing energy consumption. These control and regeneration features enable the hydraulic system to operate with improved energy efficiency, minimizing waste and maximizing force generation per unit of energy input.

5. System Integration and Optimization: Energy-efficient force generation with a double-acting hydraulic cylinder is not limited to the cylinder alone but involves the integration and optimization of the entire hydraulic system. By designing the hydraulic system with the appropriate components, such as efficient pumps, valves, and control systems, the overall system efficiency can be improved. Proper system sizing, pressure control, and fluid management contribute to minimizing energy losses and maximizing the energy efficiency of force generation.

By leveraging bi-directional operation, conserving potential energy, load counterbalancing, flow control and regeneration, as well as system integration and optimization, a double-acting hydraulic cylinder significantly contributes to energy-efficient force generation. These features make hydraulic systems with double-acting cylinders suitable for applications where energy efficiency is a priority, such as in industrial machinery, construction equipment, and mobile hydraulic systems.

How does a double-acting hydraulic cylinder differ from a single-acting one?

A double-acting hydraulic cylinder and a single-acting hydraulic cylinder differ in their functionality and ability to generate force. Here’s a detailed explanation of the differences:

1. Functionality: A double-acting hydraulic cylinder can generate force in both directions of its stroke, whereas a single-acting hydraulic cylinder can only generate force in one direction.

2. Construction: In a double-acting hydraulic cylinder, there are two hydraulic ports—one connected to the rod end and the other to the cap end of the cylinder. This allows hydraulic fluid to enter and exit both chambers of the cylinder, enabling force generation in both directions. In contrast, a single-acting hydraulic cylinder has only one hydraulic port, typically connected to the cap end. The rod end of a single-acting cylinder is often vented or equipped with a smaller hydraulic port to facilitate the return of the piston.

3. Operation: A double-acting hydraulic cylinder operates by supplying hydraulic fluid to the appropriate ports to extend or retract the piston. By controlling the flow and pressure of the hydraulic fluid, operators can regulate the direction and speed of the piston’s movement, generating pushing and pulling forces. In a single-acting hydraulic cylinder, hydraulic fluid is supplied to the port to extend the piston and generate force in one direction. The return stroke of the piston is accomplished by the force of gravity or an external mechanical load, as there is no hydraulic pressure applied to retract the piston.

4. Applications: Due to their ability to generate force in both directions, double-acting hydraulic cylinders are suitable for applications that require bidirectional force, precise control, and versatility. They are commonly used in tasks such as lifting, pushing, pulling, clamping, and more. Single-acting hydraulic cylinders, on the other hand, are often employed in applications where force is required in only one direction, such as in simple lifting or lowering tasks.

5. Efficiency: Double-acting hydraulic cylinders offer improved efficiency compared to single-acting cylinders in applications that require frequent or continuous bidirectional force. With a double-acting cylinder, the force can be applied in both the extension and retraction strokes, allowing for increased productivity and reduced cycle times.

In summary, the main difference between a double-acting hydraulic cylinder and a single-acting hydraulic cylinder lies in their ability to generate force in one or both directions. While a double-acting cylinder can generate force in both directions, a single-acting cylinder can generate force in only one direction. This distinction impacts their construction, operation, applications, and efficiency in various hydraulic systems.

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.

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.
