The reason for the emergence of oil-free gas booster pumps is that Zui in the United States produced oil-free gas booster pumps earlier, which is mainly beneficial for the development of the aviation industry and the testing of various aviation components. Due to the high requirements, the requirements for testing sources are very strict. The relevant departments have developed many testing sources and methods to produce pneumatic booster pumps and related products.
The working principle of an oil-free gas booster pump: The pneumatic gas booster pump utilizes low-pressure gas (2-8 bar) from a large area piston to generate high-pressure gas/liquid on a small area piston. It can be used for compressed air and other gases, and the output pressure can be steplessly adjusted by driving the pressure.
How to adjust the output pressure of the oil-free gas booster pump, and the output pressure and flow rate are adjusted by the pressure regulating valve of the driving gas. Adjust the driving air pressure to ensure that the output pressure of the pneumatic booster pump is adjusted between the pre increased air pressure and the larger output pressure.
The birth of oil-free gas booster pumps is of milestone significance, marking a major technological innovation and breakthrough in the gas booster pump industry, solving the dilemma of some high-tech industries being unable to use oil based booster pumps for gas pressurization. This is a major breakthrough in the history of gas booster pumps.
The raw materials used in oil-free pneumatic booster pumps are different: booster pumps and cylinders are different. The cylinders only need to apply force, and booster pumps also need to boost pressure. The conditions of various raw materials under high pressure are different. For example, the friction of aluminum alloy under high pressure can weaken the metal, causing deformation and damage to the turbocharged cylinder. All turbocharged cylinders are made of 304 stainless steel material, which can easily avoid these problems.
Skills; Most manufacturers use a single-layer cylinder body, which leads to a higher temperature rise of the boosting medium and affects the service life of the sealing ring of the boosting cylinder. The accuracy of the directional valve cannot be achieved, which affects the boosting speed of the booster pump. The sealing accuracy of the one-way valve is not good, which affects the pressure relief and maintenance.
The impact of processing equipment: strong knowledge, specialized technology, simple appearance of booster pumps, high precision requirements. For example, the exhaust hole on the directional valve should be punched with a micrometer disc and placed evenly, without affecting the directional and exhaust unevenness. The directional valve chamber should adopt high-speed precision engraving, without burrs, and control the size and accuracy of the hole position.
