LNG Low Temperature High Pressure Plunger Pump

LNG Low Temperature High Pressure Plunger Pump

LNG low-temperature and high-pressure plunger pump is suitable for low-temperature liquid pressurization systems. It has stable performance, easy operation, and convenient maintenance. Under good installation conditions, the pump start-up time is less than 10 minutes. The pump head can be independently removed and reinstalled after maintenance. This process can be completed within 2-4 hours. The flow-through design allows the pump to restart without the need for pressure relief.

The function of the pump drive end is to convert the rotational motion of the motor into reciprocating motion, and transmit the output power of the motor to the compression end of the pump head. The motor successfully converts through components such as pulleys, eccentric wheels, connecting rods, and cross heads. The camshaft and bearing structure of the transmission system are immersed in oil, which greatly extends the lifespan of the power system. The lubricating oil inside the gearbox is N46 # mechanical oil, which has been adjusted before leaving the factory.

The hydraulic end of the pump head is composed of cylinder liner, cylinder body, piston assembly, seal, inlet valve, discharge valve, etc. This pump uses PTFE filled piston rings with good wear resistance, resulting in a long working life. The seal is composed of a combination of sealing components with various sealing properties, ensuring the reliable and fault free operation of the pump under normal working pressure.
