Oil cylinder is a very important mechanical equipment, which is widely used in industrial production and mechanical equipment.

During the production of oil cylinder, the manufacturer needs to conduct pressure test on the oil cylinder to ensure that the oil cylinder can withstand the expected pressure and load.

This article will introduce Oil cylinder manufacturer Common stress test methods, test process and precautions.

The cylinder pressure test is a very critical link, which can ensure that the cylinder can work normally and ensure the smooth operation of industrial production and mechanical equipment.

The pressure test requires detailed steps and operations to obtain accurate test results.

Next, we will introduce several common stress testing methods.

1、 Hydrostatic test method

Hydrostatic test is a basic test method, which is to place the oil cylinder in the water tank and gradually increase the pressure of the control valve for testing.

Pay attention to the following issues when testing:

1. Selection of water tank: the water tank must be able to accommodate the oil cylinder and ensure that the water pressure will not change during the test.

2. Selection of control valve: the control valve needs to be able to gradually increase the pressure and gradually reduce the pressure during the test.

3. Test environment: The test environment needs to be kept safe, and no one can approach it during the test.

2、 Pneumatic test method

The pneumatic test method is a common method. It is to fill the cylinder with hydraulic oil through the hydraulic pump, and then use the air pressure to test.

Pay attention to the following issues:

1. Selection of hydraulic pump: the hydraulic pump needs to be able to fill the oil cylinder while keeping the pressure unchanged.

2. Selection of control valve: the control valve needs to be able to gradually increase the pressure and gradually reduce the pressure during the test.

3. Use of air compressor: during the test, air compressor shall be used, and attention shall be paid to the stability of its pressure.

3、 Manual test method

Manual test method is a simple test method, which requires manual control of cylinder operation.

It needs to pay attention to the following issues:

1. Operating cylinder:

The oil cylinder needs to be operated for test. During the test, the pressure should be gradually increased and gradually reduced.

2. Test record:

The test results need to be recorded so that the test data can be analyzed and processed.

In general, the cylinder pressure test requires detailed test steps to ensure the accuracy and reliability of the test results. In the process of testing, it is necessary to constantly pay attention to safety, comply with test procedures, and record test data at any time. These are necessary operations to ensure the quality and performance of the oil cylinder.
