Tanzania rack cylinder

(Tanzania rack cylinder,produced by Hengyu Hydraulic Cylinder Factory)

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

Introduction to rack cylinder:

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

The piston rod and guide sleeve function of the rack cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.

In order to ensure the service life of the rack cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the rack cylinder, causing damage to the seal and causing leakage in the rack cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

The internal leakage of the rack cylinder should be prevented when the rack cylinder is used. The internal leakage of rack cylinder includes the leakage caused by excessive wear of rack cylinder block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.

Answers to some questions about rack cylinder:

What valve is used to control cylinder expansion?
Mainly use reversing valve, but the details of the control need hydraulic control valve, hydraulic control valve can be divided into direction control valve, pressure control valve, flow control valve. The valve controls the expansion of the cylinder is the direction control valve, that is, the reversing valve. What is the meaning of two-position three-way and three-position four-way of the reversing valve? Usually according to the different working positions that can stay after the spool is moved, it can be divided into: two-position valves, three-position valves and multi-position valves. According to the number of different slide valve channels can be divided into: two-way valve, three-way valve, four-way valve, five-way valve and multi-way valve. The name of the reversing valve is called the multi-position and multi-pass reversing valve according to its working position and the number of channels.

What is the smallest cylinder size?
The smallest shape cylinder I have ever seen is a hydraulic clamping cylinder in the machine tool industry. Outer diameter 24 mm, total length 23 mm, travel 4 mm. Weighs 0.05 kg. Maximum clamping force 3500 Newtons.
