Medical industry 20 cubic meter liquid oxygen storage tank for sale price, low-temperature storage tank research and development manufacturer

Description :

　　Industrial gas filling equipment and functions:

　　1、 Composition of equipment for low-temperature liquid filling station:

　　1. Low temperature liquid storage tank with accompanying pressurization system;

　　2. Low temperature liquid pump, with two series of fixed speed and variable frequency speed regulation;

　　3. High pressure vaporizer, using a high-pressure low-temperature liquid pump as a boosting device;

　　4. Gas filling station, gas filling tube bank, can be divided into two types: filling gas and filling liquid;

　　2、 Low temperature liquid pump

　　Divided by type, reciprocating, centrifugal, and submersible pumps.

　　reciprocating piston pump

　　2.1 A reciprocating low-temperature pump consists of two main parts: the pump body and the prime mover. The pump body can be further divided into two parts: the hydraulic end and the transmission end.

　　The function of the hydraulic end (also known as the pump head) is to compress low-temperature liquid inside the pump body, converting mechanical energy into liquid internal energy and increasing the pressure of the discharged liquid.

　　The function of the transmission end is to input the power of the prime mover through the reduction mechanism and convert the rotational motion into reciprocating motion through the connecting rod mechanism.

　　2.4 The working process of the reciprocating low-temperature pump is shown in Figure 2.5. When the active cold (or plunger) moves from left to right, the volume inside the pump cylinder increases, and the pressure decreases. When the pressure of the liquid entering the pipeline is greater than the pressure in the pump cylinder, the liquid opens the suction valve under the pressure difference and enters the pump cylinder. When the crankshaft of the transmission box rotates 180 °, Huohan moves to the left. Due to the fact that low-temperature liquids are essentially incompressible, they are immediately compressed by the piston and the pressure rapidly increases. Until the liquid pressure in the pump cylinder is high enough to open the discharge valve, the low-temperature liquid is output to the discharge pipeline through the discharge valve. When the piston is pulled by the crankshaft and then moves to the right, repeat the above process.

　　2.6 The first half of the reciprocating low-temperature pump cycle is to suck in low-temperature liquid, and the second half of the cycle is to discharge low-temperature liquid. Drainage is intermittent and discontinuous.

　　2.7 The hydraulic end mainly includes a suction valve (or suction window), a discharge valve, a pump cylinder and cylinder liner, a piston (plunger), a seal, various connecting pipes, and a test tube.
