Double Acting Hydraulic Power Unit

The hydraulic power unit (HPU) is used as an oil supply unit, which is connected to several hydraulic cylinders through an external piping system to control multiple sets of valve action. The oil tank, oil pump and accumulator constitute an independent closed power oil source system. The station can be equipped with a PLC control system, which controls all internal hydraulic functions and generates signals for exchange with the control room (DCS). Control components such as hydraulic servo valves are installed directly on the hydraulic cylinder, through which the high pressure oil is pressed into the cylinder, or from which the high pressure oil is released.

This hydraulic station with special drive technology is used to control the actuator action of the main steam valve and the turbine bypass system. The power unit is optimized for a variety of applications, such as truck operations in harsh environments, long periods of heavy lifting, and other situations requiring high performance and quality products.

All parameters can be customized

Parameters of the sample

Cylinder is the most important part of construction machinery. The traditional processing method is: broaching cylinder block - fine boring cylinder block - grinding cylinder block. The rolling method is as follows: cylinder drawing cylinder block - fine boring cylinder block - rolling cylinder block. The process is three parts, but the time comparison: grinding cylinder block 1 meter is about 1-2 days, and rolling cylinder block 1 meter is about 10-30 minutes. Investment comparison: grinder or honing machine (tens of thousands to millions), hob (tens of thousands to tens of thousands). After rolling, the surface roughness of the hole is from Ra3.2 to 6.3 μ M decreases to Ra0.4 ～ 0.8 μ m. The hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the cylinder increases by 25%. If only the influence of the cylinder is considered, the service life of the cylinder can be increased by 2-3 times. The efficiency of drilling and rolling process is about 3 times higher than that of grinding process. The above data show that the rolling process is effective and can greatly improve the surface quality of the cylinder.
