(Jordan lifting hydraulic cylinder,produced by Hengyu Group）

lifting hydraulic cylinder are widely used in Jordan，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed lifting hydraulic cylinder for customers from Jordan.

Introduction to lifting hydraulic cylinder:

When the control pressure of the hydraulic system is too low, the lifting hydraulic cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.

When the long-stroke lifting hydraulic cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in lifting hydraulic cylinder head seal damage, oil leakage, and piston sleep in the lifting hydraulic cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the lifting hydraulic cylinder; The piston and the piston rod are connected with a spherical joint.

Most of the failure of the lifting hydraulic cylinder is because there is a foreign body in the lifting hydraulic cylinder into the failure of the lifting hydraulic cylinder, the most problematic is that it is difficult to determine when the foreign body is into the lifting hydraulic cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.

When producing oil lifting hydraulic cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

Answers to some questions about lifting hydraulic cylinder:

How big is the motor and oil pump for the 80 cylinder?
Pump motor selection is not only related to cylinder diameter but also speed system, it is recommended to provide system diagram and speed requirements, generally speaking, most of the 80 cylinder on the market is equipped with 3-4KW motor, 10-20 oil pump.

What kind of seal ring we should choose for 120Mpa hydraulic cylinder?
The sealing rings used in mining machinery are high pressure, which can reach 150MPa. It is generally composed of three parts, the guide ring, the sealing body and the elastomer. It's not a special structure. It's more mature. Usually said mountain circle, bud circle.
