Electric liquid nitrogen pump

Abstract

The invention provides an electric liquid nitrogen pump. An air inlet pipe, a safety valve and a vaporizing chamber are connected after improvement, the air inlet pipe is placed above the vaporizing chamber, a liquid outlet pipe, a fixation nut, a sliding sleeve and a liquid sucking pipe are connected, the fixation nut and the sliding sleeve are placed outside the outer shell of the liquid suckingpipe, the sliding sleeve and the liquid sucking pipe are fixed through the fixation nut, and position can be adjusted in a top-bottom mode. The electric liquid nitrogen pump is authentic in shape andconvenient to use. According to the electric liquid nitrogen pump, the method of blast pump electric pressurizing is applied, and using is simple and convenient. The vaporizing chamber of the electric liquid nitrogen pump is provided with the safety valve, when pressure is too high, the safety valve can automatically jump to depressurize, and using safety is guaranteed. The sliding sleeve of theelectric liquid nitrogen pump is placed outside the liquid sucking pipe, the position can be repeatedly adjusted up and down, flexible adjustment is conducted according to difference of volumes of liquid nitrogen cylinders, and the adaptation performance is large. A polytef soft hose is applied to the liquid outlet pipe of the electric liquid nitrogen pump, a black protective casing is carried, good chemical stability, abrasion resistance and good aging resistance are needed, and the electric liquid nitrogen pump is suitable for transporting the medium under the state of ultra-low temperature.

Description
