Portable Electric Hydraulic Power Pack

Under normal conditions, the oil pump supplies oil to the system, and automatically maintains the rated pressure of the system. By locking the control valve, the valve can maintain position at any position. In the working state, the hydraulic actuator is controlled by the solenoid valve, the system command signal makes the solenoid valve action, control the oil pressure and the energy release of the accumulator, and then control the cylinder slide valve, through the mechanical transmission mechanism to drive the valve, the implementation of rapid closing, normal opening and closing and test control.

The piston slips or crawls

Hydraulic cylinder piston slip or creep will make the hydraulic cylinder work unstable. The main reasons are as follows:

Internal astringency of hydraulic cylinder. Improper assembly of internal parts of the hydraulic cylinder, deformation, wear or shape and position tolerance exceeding the limit, action resistance is too large, so that the hydraulic cylinder piston speed changes with the different stroke position, slip or crawl. The reason is mostly due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases and the speed decreases. For example: piston and piston rod different center or piston rod bending, hydraulic cylinder or piston rod to guide rail installation position deviation, sealing ring installed too tight or too loose, etc. The solution is to repair or adjust, replace damaged parts and remove iron filings.

All parameters can be customized

Parameters of the sample

Cylinder is the main component of hydraulic cylinder, mine single column, hydraulic support, gun barrel and other products. Its processing quality directly affects the life and reliability of the entire product. The cylinder block has high machining requirements, and the internal surface roughness is required to be Ra0.4 ～ 0.8 μ m. Coaxiality and wear resistance are strictly required. The basic feature of the cylinder is deep hole processing, which has always troubled the processing personnel.
