Electric pressure testing pumps can be used in various places that require pressure tests and strength tests for pipelines, pressure vessels, boilers, fittings, ships, etc. The test pressure value can be adjusted as needed, and it can maintain pressure automatically.

The medium used in electric pressure testing pumps is generally clean water at room temperature, but emulsions, rust-proof water, and neutral oils with viscosity similar to water can also be used. If equipped with cleaning attachments, the machine can also be used as a cleaning machine.

The electric pressure testing pump produced by our company is an ideal device for obtaining high-pressure liquids in laboratory and hydraulic tests for various pressure vessels, pipelines, boilers, gas cylinders, valves, and fire-fighting equipment. The pressure testing pump products and supporting pressure testing and testing projects have been applied in pressure testing in the aviation field and in our development projects. They have made significant contributions to scientific research projects underground, such as high-pressure tests, deep-sea tests, space technology, high-temperature and high-pressure tests, and special-shaped pipe tests.

The electric pressure testing pump is specially designed according to the requirements of hydraulic testing. In the initial stage of pressure testing, it has a large flow rate, can quickly fill and pressurize, shortening the experimental time. When the pressure exceeds 1.6 MPa, the flow rate automatically decreases to ensure that the pressure testing process can proceed smoothly and slowly. Therefore, this pump has two flow rates at high and low pressures and can automatically switch. Any value of hydraulic testing can be conducted below the rated discharge pressure.

Advantages of electric series pressure testing pump products:

1. The electric pressure testing pump is designed according to the requirements of hydraulic testing. In the initial stage of pressure testing (four lack of work), it can quickly fill and pressurize to shorten the testing time, with a large flow rate. When the pressure exceeds 1.6 MPa (this pressure can be lowered), the flow rate automatically decreases to ensure that the pressure testing process can proceed smoothly and slowly. Therefore, this pump has two flow rates at high and low pressures and can automatically switch. Any value of hydraulic testing can be conducted below the rated discharge pressure.

2. The electric pressure testing pump is used for hydraulic testing of various pressure vessels, pipelines, valves, and steam boilers, etc., to obtain high pressure and liquids in the chamber. In the initial stage of pressure testing, it has a large flow rate, can quickly fill and pressurize to shorten the testing time. The pressure testing pump products and supporting pressure testing and testing projects have been applied in pressure testing in the aviation field and in development projects.

3. The electric pressure testing pump produced by Hongyuan Machinery Manufacturer has a compact and reasonable structure, is easy to operate, has a lightweight overall weight, is easy to maintain, is rust-proof, and the DSY type electric pressure testing pump is motor-driven, greatly improving work efficiency.

Drive mode: motor-driven, diesel engine-driven (can be used for cleaning and unclogging pipelines, and can also be used for pipeline pressure testing).

Method of using the electric pressure testing pump:

1. Before using the electric pressure testing pump, check in detail whether all parts are tightly connected, whether the pressure gauge is normal, and whether the inlet and outlet water pipes are properly installed. It is prohibited to use unclean water containing mud and other contaminants.

2. To improve testing efficiency, the tested container or equipment can be filled with water first, and then connect the outlet pipe of the pressure testing pump.

3. During the pressure testing process, if a large amount of air is found in the water, the drain valve can be opened to release the air.

4. If any slight water mixing phenomenon is found during the pressure testing process, work should be stopped immediately for inspection and repair. It is strictly prohibited to continue increasing pressure in the case of water mixing.

5. After the pressure test is completed, first open the drain valve to allow the pressure to drop to avoid damaging the pressure gauge.

6. When the electric pressure testing pump is not in use, the water inside the pump should be drained, and a small amount of machine oil should be sucked in to prevent rust.

 Precautions for using the electric pressure testing pump:

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

2. The pressure gauge on the outlet pipe of the electric pressure testing pump should meet the requirements, and a buffer pipe should be installed below the pressure gauge. The bottom of the water suction pipe should be equipped with a filter screen; a safety valve should be installed on the electric high-pressure pump.

3. The water used for pressure testing should be clean, and the tested pipeline or container should be filled with water and air should be discharged before pressure testing can be conducted.

4. When using the electric pressure testing pump, the speed should be uniform and not too abrupt. If equipped with high and low pistons, when the low-pressure piston is difficult to pressurize, the high-pressure piston should be switched to use in time.

5. When the pressure of the tested pipeline system or container reaches the required level, close the valve connected to the pressure testing pump and observe the pressure drop over time. 6. After the pressure test is completed, the water should be discharged in an orderly manner into the outdoor sewage or rainwater drainage system, and should not be discharged randomly on the construction site.

7. When transporting the pressure testing pump, the pressure gauge and vulnerable parts should be removed; if not used for a long time, it should be cleaned, oiled, and stored properly. The electric pressure testing pump is widely used for hydraulic testing of various pressure vessels, pipelines, valves, steam boilers, chemical machinery, and other pressure-bearing components, providing high-pressure liquids to the testing laboratory or serving as a power source for high-pressure water jet cleaning and cutting equipment.

Pressure testing pump maintenance and repair

1. Before using the pressure testing pump, the manufacturer should check in detail whether all parts are tightly connected, whether the pressure gauge is normal, and whether the inlet and outlet water pipes are properly installed. The working medium for this pump is clean water, emulsion, or working viscosity <45 mm2/s. It is prohibited to use unclean water containing mud and other contaminants.

2. To improve testing efficiency, the tested container or equipment can be filled with water first, and then connect the outlet pipe of the pressure testing pump.

3. During the pressure testing process, if a large amount of air is found in the water, the drain valve can be opened to release the air.

4. If any slight water mixing phenomenon is found during the pressure testing process, work should be stopped immediately for inspection and repair. It is strictly prohibited to continue increasing pressure in the case of water mixing.

5. After the pressure test is completed, first open the drain valve to allow the pressure to drop to avoid damaging the pressure gauge.

6. When the pressure testing pump is not in use, the water inside the pump should be drained, and a small amount of machine oil should be sucked in to prevent rust.
