(Angola aluminum alloy cylinder,produced by Hebei Hengyu company）

aluminum alloy cylinder are widely used in Angola，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed aluminum alloy cylinder for customers from Angola.

Introduction to aluminum alloy cylinder:

aluminum alloy cylinder hydraulic oil selection: The recommended working oil viscosity of the aluminum alloy 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.

If the aluminum alloy cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.

Causes and countermeasures of oil aluminum alloy cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the aluminum alloy cylinder will lead to premature wear of the piston seal, replace the piston seal; If the aluminum alloy cylinder is visibly scarred, the aluminum alloy cylinder must be replaced. It can be pressurized at one end of the aluminum alloy cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most aluminum alloy cylinder piston drift may not come from the aluminum alloy cylinder, the above method to determine the aluminum alloy cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

If air enters the hydraulic system, the aluminum alloy cylinder will not operate normally, mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced.

Answers to some questions about aluminum alloy cylinder:

What's a minus 40 cylinder made of?
Construction with 1Cr18Ni9Ti, in low temperature conditions impact and tensile strength are very good, can withstand -100 degrees of low temperature, corrosion resistance, material price is not very high, more economic.

What is the meaning of cylinder ejection on the injection mold, and what is the difference between cylinder ejection and ordinary ejection?
Usually requires the front die ejection will use the cylinder to drive the thimble plate to achieve the ejection of the thimble. There is also a case that the mold is very large or long, and the balance of the ejector rod of the injection molding machine is not enough, and the cylinder ejector will also be used.
