Small-sized high-purity gas electric pressurizing equipment

Abstract

The invention discloses small-sized high-purity gas electric pressurizing equipment. The small-sized high-purity gas electric pressurizing equipment comprises an oil-free plunger pump, a driving motorand an automatic starting and stopping device. The driving motor rotates to drive the oil-free plunger pump connected with one end of a rotor shaft through the torque for high-purity gas automatic pressurization; the oil-free plunger pump completes the effect of pressurizing the low-pressure gas into the high-pressure gas in such way that a plunger performs the reciprocating motion in a cylinderbody to cause the change of a seal volume, and the output pressure can be increased by adopting a multi-stage pressurization mode; the oil-free plunger pump selects bottled high-purity gas as a gas inlet source according to a tested piece test function requirement, and a multi-stage oil-free electric pressurizing structure of an electric pump and the automatic starting and stopping device of the pressurizing equipment are reasonably designed; and the automatic starting and stopping device completes the automatic starting and stopping operation of the electric pressurizing equipment through anpneumatic gas inlet valve, a pneumatic output valve and an electric pump circulation bypass, non-load operation of the electric pump is realized, and the situation that due to motor load gas operating, the electric current is too large, and then the motor is burnout is avoided.

Description

technical field [0001] The invention relates to a small electric supercharging device for high-purity gas, which can provide high-purity gas at a constant pressure within the pressure range of 0-70 MPa, and specifically belongs to the technical field of multi-stage supercharging equipment. Background technique [0002] As a power and test air source, high-pressure air source is widely used in aerospace, aviation, shipbuilding, chemical, pharmaceutical and other industries, and has an irreplaceable role. The basis for the safe and normal operation of the high-pressure air supply system is scientific design and reasonable installation. ; [0003] At present, the gas supply equipment of high-pressure gas sources is relatively large in size, and the gas supply pressure cannot meet the requirements of power and testing. Large, low portability, inconvenient to move, limited to off-site use, and the pressure value of the high-pressure air source is not high, which cannot meet the ...
