Discussion on the Application Prospect of Flashlight Pump in China

What is manual pump current manual pump case

Manual pump is a kind of hydraulic pump. As a power source for the hydraulic system, it is mainly composed of fluid (hydraulic oil, saponified oil, water, etc.) as a medium. The manual hydraulic pump is generally a horizontal piston design, and the ultrahigh-pressure manual pump is a super-high pressure generated by the double-piston conversion.

After running and testing with the domestic market, the current production of ultra-high pressure manual hydraulic pump fully meets the market demand, the working pressure is 100 ~ 300Mpa; built-in pressure relief valve, in order to prevent pressure overload, the pump is also equipped with safety release valve; Two-stage flow design, with a displacement of 33CC at the first-order low pressure and 1.6cc at the second-order high pressure; realizing the constant power condition, low-pressure and large-flow oil supply, high-pressure and small-flow oil supply, saving time and improving efficiency . The external dimensions are 585*120*170mm and the total weight of oil is about 11Kg. The use of this pump indicates that the pump is convenient and flexible, low in labor intensity, and durable, and is an ideal ultra-high pressure hydraulic power source.

The application prospect of ultra-high pressure manual hydraulic pump

1. Threaded fasteners and power sources for tightening and tensioning devices. Precise control of the bolt can be achieved, and the working pressure of the hydraulic oil can reach 300Mpa. At present, China's coal, electricity, chemical industry and other industries are using high-strength hydraulic nuts or hydraulic tensioners, ultra-high pressure manual night pump as a power source, and achieved good results.

2. The power source for the disassembly and assembly of smooth conical or cylindrical surfaces in mechanical equipment. Hydraulic nut is an effective tool for the interference fit of smooth conical and cylindrical surfaces such as bearings, gears, and rotors. It consists of an annular piston with a sealing ring and nuts with internal threads. The ultra-high pressure manual hydraulic pump is used as the power source, and the ultra-high pressure enters from the round surface or the end surface of the nut body, so that a relative movement occurs between the piston and the nut body, thereby achieving the disassembly and assembly of the interference fit.

3. Power source for hydraulic load cylinders or jacks. It is the ideal tool for heavy equipment installation and debugging.
