Characteristics and principles of high-pressure air pump

by:WORKSITE     2020-07-02
Mechanical characteristics 1. High output pressure: the pressure can reach 560Mpa 2. Wide range of use: the working medium can be hydraulic oil, water and most chemically corrosive liquids, and it has high reliability and long maintenance-free life. 3. Wide output range: For all models of pumps, only a small air pressure is required to work smoothly. At this time, a small flow rate is obtained, and different flow rates can be obtained after adjusting the intake air amount. 4. Flexible application: choose different types of pumps to obtain different pressure areas. Battery electric air pump 5. Easy to adjust: within the pressure range of the pump, adjust the regulating valve to adjust the intake pressure, and the output hydraulic pressure will be adjusted accordingly. 6. Automatic pressure holding: no matter what causes the pressure of the pressure holding circuit to drop, it will automatically start to supplement the leakage pressure and keep the circuit pressure constant. 7. Operational safety: It is driven by gas, without arc and spark, and can be used in dangerous places. 8. Simple maintenance: Compared with other air-driven pumps, the booster pump can accomplish the same work, but its parts and seals are few, and maintenance is simple. 9. High cost performance: The booster pump is a plunger pump, and the booster pump reciprocates rapidly during operation. Mechanical principle For whatever reason, the pressure of the air pump causes the pressure of the pressure-holding circuit to drop, and the booster pump will automatically start to supplement the leakage pressure and keep the circuit pressure constant. Operation safety: It is driven by gas without arc and spark, and it is completely used in places with flammable and explosive liquid or gas. Simple maintenance and high cost performance: the booster pump is a plunger pump Car air pump During operation, the booster pump reciprocates rapidly. As the output pressure increases, the pump reciprocates slowly until it stops. At this time, the pressure of the pump is constant, the energy consumption is low, and the components stop moving. Micro pumps used for inflation are divided into two categories: gas sampling pumps and micro vacuum pumps. Although they are generally referred to as micro vacuum pumps without distinction, they are different from a technical point of view, and special attention should be paid when selecting models. Gas sampling pumps are: PM series (specific models such as: PM950.2, PM850.5, PM8001, PM7002, PM6503); micro vacuum pumps are: VM series, VAA series, PK series, PC series, VCA series, VCC series, VCH Series, PH series, FM series, FAA series, PCF series, all specifications under these series are true miniature vacuum pumps, such as VM7002, VAA6005, PC3025, etc. The magnitude of the resistance of the air-filled end of the micro-pump can be measured with an instrument, and it can be known whether the selection is appropriate by comparing it with the Por value of the pump's technical parameter 'air inlet allows large resistance'. It is usually determined by a simple method based on experience. For example, the following situations are all with a large load (that is, the resistance of the suction end of the pump is large), and can only be selected within the scope of the micro vacuum pump: ① At the suction end of the pump Connect a long pipeline, or the pipeline has many bending points, severe bending or even blockage, or the inner hole of the pipeline is very small (such as less than φ2 mm); ②There are throttle valves, solenoid valves, gas circuit switches, filters on the pipeline And other components; ③ The pump suction port is connected to a closed container, or the container is not closed but the air intake is small; ④ The pump suction port is connected to a suction cup for adsorbing objects (such as integrated blocks, precision workpieces, etc.); ⑤ The pump The suction end is connected to the filter container, and a filter screen is placed at the mouth of the container to accelerate the liquid filtration.
