Characteristics and operating principle of the high pressure pump

Mechanical characteristics

 

1. High output pressure:** The pressure can reach 560MPa.

2. Wide application range:** The working medium can be hydraulic oil, water and most chemically aggressive liquids. The pump has high reliability and long service life without the need for maintenance.

3. Wide range of output pressure:** All pump models require only a small pressure to operate stably. Adjusting the volume of incoming air allows you to get different flow rates.

4. Flexibility in application:** A choice of different pump models allows you to achieve different pressure ranges.

5. Easy to adjust:** Within the pump pressure range, the inlet pressure can be adjusted through the regulating valve, which will result in stepless adjustment of the outlet pressure.

6. Automatic pressure maintenance:** Regardless of the reason for the pressure drop in the pressure maintenance circuit, the pump automatically starts to compensate for the pressure leak and maintain it at a constant level.

7. Operational safety:** Gas driven, no electric arcs or sparks, allowing the pump to be used in hazardous areas.

8. Easy to maintain:** Compared with other air pumps, the booster pump can do the same job but with fewer parts and seals, making it easier to maintain.

9. High price-quality ratio:** The booster pump is a piston pump. During operation, it quickly performs reciprocating movements.

 

Mechanical principle

 

Regardless of the cause of the pressure drop in the pressure maintenance circuit, the booster pump will automatically start to compensate for the pressure leakage and maintain it at a constant level. **Safety in operation:** Gas drive device is used, there are no electric arcs and sparks, which allows it to be used in places with flammable or explosive liquids or gases. **Easy maintenance and high price-quality ratio:** The booster pump is a piston pump that performs a rapid reciprocating motion during operation. As the output pressure increases, the reciprocating speed of the pump slows down until it stops completely, while the pressure in the pump remains constant, energy consumption is low, and all its parts stop.

 

Miniature pumps used for pumping are divided into two types: air sampling pumps and miniature vacuum pumps. Although they are often simply called miniature vacuum pumps, there are technical differences between the two, and this is especially important to consider when choosing.

 

Air sampling pumps include: PM series (specific models, such as PM950.2, PM850.5, PM8001, PM7002, PM6503); miniature vacuum pumps include: VM, VAA, PK, PC, VCA, VCC, VCH, PH, FM, FAA, PCF series, all models of which are true miniature vacuum pumps, such as VM7002, VAA6005, PC3025 and so on.

 

The resistance size on the pumping side of the miniature pump can be measured with an instrument and compared with the parameter of "maximum allowable inlet resistance" (Por) to determine whether the selected model is suitable. Generally, simplified determination methods based on experience are adopted. For example, in the following cases, the resistance on the pumping side is considered to be high (i.e., the resistance on the suction side of the pump is large), and the pumps should only be selected from the miniature vacuum pump category: ① The suction side of the pump has long pipelines, or the pipelines have many bends, are severely bent, or may even be blocked, or the inner diameter of the pipeline is very small (such as less than 2 mm); ② There are throttle valves, solenoid valves, air line switches, filters and other elements in the pipeline; ③ The suction port of the pump is connected to a sealed container, or although the container is not sealed, the intake air volume is very small; ④ The suction port of the pump is connected to a suction cup used to grip objects (such as integrated circuits, precision parts, etc.); ⑤ The suction port of the pump is connected to a filter container in which a filter is installed to accelerate the filtration of liquid.
