The reason for the emergence of all-oil-free booster pumps is that all-oil-gas-free booster pumps originated in the United States at the earliest time, mainly for the development of the aviation industry, various aviation components testing, because the requirements are relatively high, the test source requirements are very strict. Relevant departments have developed a lot of testing sources and methods, resulting in pneumatic booster pumps and related products.
The working principle of all-oil-free supercharged pump is that pneumatic gas supercharged pump uses low pressure gas (2-8bar) of large area piston to drive and produces high pressure gas/liquid on small area piston. It can be used to compress air and other gases, and the output air pressure can be adjusted stepless by driving air pressure.
How to adjust the output pressure of all-oil-free booster pump, the output pressure and flow are accurately regulated by the pressure regulating valve of driving gas (purchased separately). Adjust the driving pressure, so that the output pressure of the pneumatic booster pump can be accurately adjusted between the pre-boost pressure and the maximum output pressure.
The birth of all-oil-free supercharged pump is of milestone significance. It marks a major technological innovation and breakthrough in the gas supercharged pump industry, and solves the predicament that some high-end industries can not use oil supercharged pump for gas supercharged. It is a major breakthrough in the history of gas booster pump.
Different raw materials; supercharger pump is not the same as the cylinder, only the lower force, but also the condition of various materials under high pressure is different, such as aluminum alloy under high pressure back friction will cause metal weakness phenomenon leading to deformation and damage of the supercharger cylinder, all 304 stainless steel supercharger cylinder can easily avoid these problems.
Skills: Most manufacturers use single-layer cylinder block, which results in high temperature rise of the pressurized medium and affects the life of the pressurized cylinder seal ring. The precision of the reversing valve is not enough to affect the boosting rate of the booster pump. The sealing accuracy of one-way valve is not good, affecting the holding pressure and slow charging.
The impact of processing equipment: learning is good, specializing in technology, supercharged pump looking at the simple practice of high precision requirements, such as the reversing valve on the exhaust holes, to use the pin plate to punch large and small holes and uniform placement does not affect the reversing and exhaust unevenness. The reversing valve chamber should be carved with high speed carving, without burrs and precise size of control holes.
