(Tanzania garbage truck hydraulic cylinder,produced by Hengyu Group）

garbage truck hydraulic cylinder are widely used in Tanzania，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed garbage truck hydraulic cylinder for customers from Tanzania.

Introduction to garbage truck hydraulic cylinder:

In the process of using the garbage truck hydraulic cylinder, sometimes such a problem will occur, the garbage truck hydraulic cylinder can not act immediately after the instruction of the garbage truck hydraulic cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil garbage truck hydraulic cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

The cavitation of the garbage truck hydraulic cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the garbage truck hydraulic cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.

garbage truck 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.

In recent years, the processing process of the garbage truck hydraulic cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.

Answers to some questions about garbage truck hydraulic cylinder:

What is the material of the hydraulic cylinder slider?
Three parts of the hydraulic cylinder are essential, which are: cylinder - cylinder head assembly, piston - piston rod assembly, and sealing device. When you say slider, you mean piston. - Piston rod. Piston materials commonly used gray cast iron, wear-resistant cast iron, aluminum alloy (assembled), etc., can also be used 35 and 45 steel (integral). The piston rod is generally made of 35 and 45 steel. When the impact vibration is large, alloy steel such as 55 steel or 40Cr is used.

How to calculate cylinder pressure?
Hydraulic pressure area of cylinder × hydraulic pressure = output force of cylinder 200mm=20cm 100mm=10cm 15Mpa=150Kg/cm2 Cylinder thrust: 3.14×10×10 area ×150 pressure =47100Kg=47.1t cylinder pulling force: 3.14×(10×10-5×5) Area ×150 pressure =35325Kg=35.325t The above calculation did not consider the resistance of oil return, because you did not provide oil return pressure. But the impact should be small.
