Vacuum pressure hand pump

 Vacuum pressure hand pump, measurement range to 0.088-2.5 MPa.
Hand pressure type pump is a kind of liquid hand pump. Used to check in the industrial process field calibration instrument installation and control of indoor use all kinds of pressure gauges. Can also be used for pressure source table provides pressure measuring instrument manufacturer. Every 25 mpa within all kinds of pressure transmitter, pressure sensor and all kinds of pressure gauges are available hand check pressure pump.
Features:
Hand pressure pump is a portable, light weight, suppression of light. Easy to use. The structure design pressure fine-tuning hand, rotating fine-tuning hand can easily change the output pressure. In addition, with high pressure hose connection is timing, meter connector to connect pressure gauge. Hand pressure pump can be carried to the scene and calibrated instruments are connected directly, calibration is quick and easy
The structure and working principle
Hand pressure pump is the handle, the piston rod. Through gas, pump cover, put the oil hand, fine-tuning hand, form joint, etc. Rotary oil drain hand to close the drain valve, hand shake hands hold pressure pump handle, forcibly hold, relax iterative, so as to drive the reciprocating motion of the piston rod, the output pressure caused by the reciprocating motion of the piston rod can be several times - 0.088-2.5 MPa.
