Lifting cylinder Sold to Portugal

This article mainly introduces:

Portugal hydraulic cylinder,Lifting cylinder manufacturer,Lifting cylinder

(Portugal Lifting cylinder,produced by Hebei Hengyu company）

Lifting cylinder are widely used in Portugal，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed Lifting cylinder for customers from Portugal.

Introduction to Lifting cylinder:

The material, shape and compression of the Lifting cylinder seal have a great impact on the service life and work efficiency of the Lifting cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.

If the seal of the Lifting cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and Lifting cylinder, and the phenomenon of "pulling the Lifting cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

The Lifting cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the Lifting cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the Lifting cylinder wall due to the stiffness and the weight of the parts, causing scars.

The Lifting cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the Lifting cylinder, bite. Elimination method: When installing the Lifting cylinder, ensure that the axis position of the Lifting cylinder is consistent with the direction of movement; Make the load borne by the Lifting cylinder as far as possible through the Lifting cylinder axis, to avoid the phenomenon of eccentricity.

Answers to some questions about Lifting cylinder:

What is the cause of sound and vibration when the hydraulic cylinder is under load?
The main reason 1) may be that the load machinery has stuck phenomenon, and the resistance is large. 2) The hydraulic oil is not enough, or the filter is blocked by dirty things, and the oil is flooded. 3) There is a problem with the pump.

What's the use of three oil pipes on the cylinder?
The cylinder usually has an upper and lower oil chamber, one is connected to the upper oil chamber, one is connected to the lower oil chamber, sometimes a hydraulic lock will be added, that is, a hydraulic control check valve to prevent accidents when the oil pipe breaks, so the third pipe should be the control oil pipe of the hydraulic control check valve.
