Vietnam lift hydraulic cylinder

(Vietnam lift hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)

lift hydraulic cylinder are widely used in Vietnam,because of long service life,smooth movement,high work efficiency.So our company has designed lift hydraulic cylinder for customers from Vietnam.

Introduction to lift hydraulic cylinder:

lift hydraulic cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.

There are some honeycomb holes in the inner wall of the lift hydraulic cylinder, piston or piston rod surface. How is this formed? When we repair the lift hydraulic cylinder, we can see that there are some honeycomb holes on the inner wall of the lift hydraulic cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the lift hydraulic cylinder is targeted to prevent. Is very necessary.

lift hydraulic cylinder hydraulic oil selection: The recommended working oil viscosity of the lift hydraulic cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

In use, the lift hydraulic cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the lift hydraulic cylinder.

Answers to some questions about lift hydraulic cylinder:

Hydraulic cylinder performance requirements?
Hydraulic cylinder performance requirements: hydraulic cylinder is the hydraulic system to achieve energy transfer, conversion and control of the working medium, in addition, it is also responsible for the lubrication of the system, rust prevention, corrosion prevention and cooling. The performance of hydraulic oil will make the system flexible, accurate and reliable. Hydraulic performance requirements are determined according to the design parameters of the hydraulic system, operating conditions, the structure of the hydraulic pump and the working environment. Appropriate viscosity and good viscosion-temperature performance Viscosity is an important performance indicator of hydraulic pressure, which has an important impact on the smooth operation of the hydraulic system and the friction parts. The low temperature performance of hydraulic oil includes three aspects: low temperature flow, low temperature start-up and low temperature pumping.

There are four cylinders in the front top of the dump truck. When the second cylinder is lifted to half the height, it suddenly falls back more than 30 cm or so, and the cylinder continues to lift.
The problem is the cylinder, the second section of the different strength of the heart. When the oil supply resistance is small, the first out, when the power is not moving, the cylinder needs to be strong, because the second section needs to pop it out after a while when the pressure is large, the oil can not keep up, so it falls back, and the oil continues to keep up.
