The ultra-high pressure manual hydraulic pump is an ideal power source for electromechanical assembly equipment, and is currently used in the following aspects:
1. Threaded fasteners and power source for fastening the tensioning device.
Precise control of the bolt pre-tightening force can be achieved, and the working pressure of the hydraulic oil can reach 300Mpa. At present, China's coal, electric power, chemical and other industries use high-strength hydraulic nuts or hydraulic tensioners, and the ultra-high pressure manual night pump is used as the power source, and has achieved good results.
2. The power source of smooth conical surface or cylindrical surface in mechanical equipment is disassembled and disassembled.
The hydraulic nut is an effective tool for the interference fit of the smooth conical surface and the cylindrical surface of the bearing, gear, rotor, etc. It consists of an annular piston with a sealing ring and a nut with internal threads. The ultra-high pressure manual hydraulic pump is used as the power source, and the ultra-high pressure enters from the outer surface or the end surface of the nut, so that the relative movement between the piston and the nut body is generated, thereby achieving the disassembly and assembly of the interference fit.
3. Power source for hydraulic load cylinders or jacks.
It is an ideal tool for installation and commissioning of heavy equipment.
