Working principle and usage precautions of liquid booster pump

Principle of liquid booster pump:

One of the important functions of pneumatic booster pumps is to boost liquids, such as water, oil, emulsions, and other non corrosive liquids. The liquid booster pump adopts a single gas controlled non-equilibrium gas distribution valve to achieve automatic reciprocating motion of the pump. The gas driven part of the pump body is entirely made of aluminum alloy, and the aluminum alloy components are processed and oxidized to black, ensuring the product's beautiful appearance and never rusting. The material of the liquid receiving part is selected from carbon steel or stainless steel according to different media, and the complete set of seals for the pump are all imported high-quality products, thus ensuring the performance of the pump. The drive piston diameter is divided into two specifications: 160mm and 80mm. The maximum driving air pressure is 10 bar. To ensure the lifespan of the pump, it is recommended to use an air pressure of ≤ 8 bar.

Precautions for using liquid booster pump:

Choose the appropriate boost ratio based on the pressure of the tested component, leaving room for excess pressure;

Be sure to pay attention to the choice of traffic, and the selected traffic should be moderate;

When testing the test piece, it is necessary to evacuate the internal air;

The driving pressure of the liquid booster pump and the pressurized medium should be kept clean;

Choose a pump or a liquid pressurization system based on your own operating conditions;

Production and testing standards for liquid booster pumps:

SY/T5127-2002 and API16A

SY/T5053.1-2000 and API16A

API16A

Terminology for liquid booster pumps

*The boost ratio is the area of the driving piston divided by the area of the liquid plunger

*The outlet pressure is the static outlet pressure (estimated value and maximum allowable value) of the air driven pressure at 8 bar

*The flow rate is the approximate flow rate when the air driven pressure is 6 bar and the outlet pressure is 0

*The minimum driving pressure required for a liquid booster pump is 3 bar, and a certain output pressure needs to be achieved according to a specific pressure ratio
