Electric pressure test pumps can be used in places where pressure test and strength test are required for various types of pipelines, pressure vessels, boilers, pipe fittings, ships, etc. The pressure value can be tested as required, and the pressure can be automatically maintained.

The operating medium of the electric pressure test pump is generally clean water at room temperature. Emulsion, anti-rust water and neutral oil with similar viscosity to water can also be used. If equipped with cleaning accessories, the machine can also be used as a cleaning machine.

The electric pressure pump produced by our company is an ideal equipment for obtaining high-pressure liquid in various pressure vessels, pipelines, boilers, steel cylinders, valves, pressure vessels, and fire-fighting equipment in laboratories and hydraulic tests. The pressure test pump products and supporting pressure test and test engineering have been applied to the pressure test in the aviation field, and are applied in our development projects. It has made great contributions to scientific research projects such as: high pressure test, deep sea test, space technology, high temperature and high pressure test, special-shaped pipe test, etc.

The electric pressure test pump is specially designed according to the requirements of water pressure test. In the initial stage of the pressure test, it has a large flow rate, can quickly fill and increase the pressure, so as to shorten the experiment time. When the pressure exceeds 1.6MPa, in order to make the pressure test process more stable and slow. Then the flow is automatically reduced. Therefore, the pump has two flow rates at high and low pressures, and can automatically change. Any value of water pressure test can be carried out below the rated discharge pressure.

Advantages of electric series pressure test pumps:

1. The electric pressure test pump is designed according to the requirements of water pressure test. In the initial stage of pressure test (four lack of work), it can quickly fill and increase the pressure to shorten the test time and have a larger flow rate. When the pressure exceeds 1.6Mpa (this pressure can be lowered), in order to make the pressure test process more stable and slow, the flow will automatically decrease. Therefore, the pump has two flow rates and can change automatically when it is high and low. Any value of water pressure test can be carried out below the rated discharge pressure.

2. The electric pressure test pump is used for various pressure vessels, pipelines, valves and steam boilers for water pressure test and to obtain high pressure and liquid in the chamber. It has a large flow in the initial stage of pressure test and can quickly fill and boost pressure. In order to shorten the test time, the pressure test pump products and supporting pressure test and test engineering have been applied to the pressure test in the aviation field and applied in development projects.

3. The electric pressure test pump produced by Hongyuan Machinery manufacturer has the characteristics of compact structure, reasonable, labor-saving operation, light weight, convenient maintenance, and anti-rust. The DSY electric pressure test pump is driven by a motor, which greatly improves work efficiency. .

Drive mode: motor drive, diesel engine drive (can be used to clean and dredge pipelines, and can also be used for pipeline pressure test).

How to use electric pressure test pump:

1. Before using the electric pressure test pump, check whether the connection of each component is tightened, whether the pressure gauge is normal, and whether the water inlet and outlet pipes are installed properly. It is forbidden to use unclean water with silt and other pollutants.

2. In order to improve the efficiency of pressure test, the container or equipment under test can be filled with water first, and then the outlet pipe of the pressure test pump can be connected.

3. During the pressure test, if you find a lot of air in the water, you can open the water valve to let the air out.

4. If any slight water mixing is found during the pressure test, the work should be stopped immediately for inspection and repair. It is strictly forbidden to continue to increase the pressure in the case of water mixing.

5. After the pressure test is completed, first loosen and open the water valve to reduce the pressure to avoid damage to the pressure gauge.

6. When the electric pressure test pump is not in use, drain the water in the pump and suck in a small amount of oil to prevent corrosion

 Precautions for the use of electric pressure test pumps:

1. The electric pressure test pump should be placed steadily, and the connecting pipe with the pressure test piping system should not be too long.

2. The grade of the pressure gauge on the outlet pipe of the electric pressure test pump should meet the requirements, and a buffer tube should be installed under the pressure gauge. A strainer should be installed at the bottom of the suction pipe; a safety valve should be installed on the electric high-pressure pump.

3. The pressure test water should be clean, and the test pipe or container should be filled with water and exhausted before the pressure can be carried out.

4. When using an electric pressure test pump, the speed should be uniform and not excessive. If equipped with high and low pistons, when the low pressure piston is struggling to press, the high pressure piston should be switched in time.

5. When the pressure of the tested piping system or container reaches the requirement, the valve connected to the pressure test pump is closed, and the pressure drop is observed at a time. 6. After the pressure test is completed, the water should be discharged into the outdoor sewage or rainwater pipe network in an orderly manner, and shall not be discharged at the construction site at will.

7. When transporting the pressure test pump, the pressure gauge and vulnerable parts should be removed; when it is not used for a long time, it should be cleaned and oiled and stored properly. Electric pressure test pumps are widely used for hydraulic testing of pressure-bearing parts such as various pressure vessels, pipelines, valves, steam boilers, chemical machinery, etc., to provide high-pressure liquid to the laboratory or as a power source for high-pressure water jet cleaning and cutting equipment.

Suppressing pump use and maintenance

1. The pressure test pump manufacturer should check in detail whether the connection of each component is tightened before use, whether the pressure gauge is normal, whether the inlet and outlet pipes are installed properly, the working medium of the pump is 5~50°C water, emulsion or kinematic viscosity <45mm2 s=" "span="">Use unclean water with mud, sand and other pollutants.

2. In order to improve the efficiency of pressure test, the container or equipment under test can be filled with water first, and then the outlet pipe of the pressure test pump can be connected.

3. During the pressure test, if you find a lot of air in the water, you can open the water valve to let the air out.

4. If any slight water mixing is found during the pressure test, the work should be stopped immediately for inspection and repair. It is strictly forbidden to continue to increase the pressure in the case of water mixing.

5. After the pressure test is completed, first loosen and open the water valve to reduce the pressure to avoid damage to the pressure gauge.

6. When the pressure pump is not in use, drain the water in the pump and suck in a small amount of oil to prevent corrosion.
