220v Hydraulic Power Pack

The hydraulic power unit is an independent power system in hydraulic machinery. It is used as an oil supply device and is connected to several hydraulic cylinders through an external pipeline system to control multiple sets of valve actions. Its construction usually includes a fluid reservoir, pump and motor. Its job is to apply the hydraulic pressure required to drive motors, cylinders, actuators and other hydraulic system components.

The result is an extremely versatile platform that uses standard components to cope with most of the application conditions required by the market, which minimizes the customer's hydraulic component inventory and greatly reduces the workload of non-standard design.Power units also make special applications more cost-effective.
The HE power unit, for example, is built on a versatile platform that allows motor sizes from 80 to 132mm(0.3 to 4.5kw) and pump displacement from 0.24 to 5.7cc. One power unit can control up to 4 hydraulic cylinders. The core component of the system is the adapter. There are two different sizes. Available in a variety of shapes and mounting modes.

All parameters can be customized

Parameters of the sample

Due to the residual compressive stress on the surface, rolling processing helps to close the small cracks on the surface and prevent the expansion of erosion. Therefore, the corrosion resistance of the surface can be improved, and the generation or propagation of fatigue cracks can be delayed, so as to improve the fatigue strength of the cylinder. Through rolling forming, a cold work hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface caused by grinding, thus improving the wear resistance of the cylinder inner wall and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the compatibility.

HCIC is a one-stop telescopic hydraulic cylinder manufacturer with rich experience in customizing and designing hydraulic cylinders for boom trucks. HCIC can design and produce hydraulic cylinders no matter how complex. We adopt European technology and American standards to provide customers with a full set of customized services from design to delivery. Our standard oil cylinders include rod hydraulic cylinder, walking machine hydraulic cylinder, welding oil cylinder, snow shovel oil cylinder, telescopic oil cylinder, hydraulic dump oil cylinder, woodcutter hydraulic cylinder, loader hydraulic cylinder, and hydraulic bucket tilt oil cylinder. We can also customize it.

The piston slips or crawls

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

(1) Hydraulic pump or hydraulic cylinder into the air. Compression or expansion of air can cause the piston to slip or crawl. Elimination measures are to check the hydraulic pump, set up a special exhaust device, fast operation of the whole trip back and forth several times exhaust.

(2) Seal quality is directly related to slip or creep. When the O-shaped sealing ring is used under low pressure, compared with the U-shaped sealing ring, it is easy to slip or crawl due to the high surface pressure and the large difference between dynamic and static friction resistance; The surface pressure of U-type sealing ring increases with the increase of pressure, although the sealing effect is also increased accordingly, but the difference between dynamic and static friction resistance is also larger, the internal pressure increases, affecting the rubber elasticity, due to the increase of contact resistance of lip edge, the sealing ring will tip over and lip edge elongation, and it is easy to cause slip or creep, in order to prevent its tip over, the support ring can be used to maintain its stability.
