The reciprocating cryogenic hydraulic pump is applicable in the filling system of liquid oxyen, liquid nitrogen, and liquid argon. It pressurizes, vaporizes the low temperature liquid in storage tank, and fills it into steel cylinder. Large-flow reciprocating cryogenic hydraulic pump is used in mid-pressure technology system of liquid oxygen, liquid nitrogen and liquid argon, and pressureizes, vaporizes the low temperature liquid in storage tank, fills it directly into pipe netting.
   Carbon dioxide hydraulic pump is the main part for carbon dioxide filling system. It pressurizes the liquid carbon dioxide, and fills it into steel cylinder. Its simple and optimized design, and elaborate production assure its long-time safe operation. The pump mainly consists of motor, electric controlling cabinet, strap wheel, drive wheel, wheel box and pump head. The driving terminal of pump is to turn pump's whirligig to reciprocation, and transmit the output power of motor to header compression of pump. The motor completes its turning through strap wheel, centrifugal wheel, connecting rod level, and crosshead. The axis, cam and bearing structure of drive system is of oiliness type.
Performance :
★Drive system is of connecting rod level and crosshead structure, and has long lifespan.
★High pressure reciprocating cryogenic hydraulic pump adopts the high-vacuum cold end clamping pump head, with little cold loss and liquid loss.
★Inside filter, practical and reliable
★Piston ring and sealing ring are made of macro-molecular compound material of good wearability. It has long lifespan, and normally works for 150 thousand cylinders.
★Convenient operation. The start-up time is within five minutes.
★The running of pump will not increases pressure in storage tank, but will reduce it after long time operation.
★Low energy consumption and low noise.
★Simple structure, easy for maintenance.
