Brazil hydraulic cylinder,rack cylinder manufacturer,rack cylinder
(Brazil rack cylinder,produced by Hengyu Hydraulic Cylinder Factory）
rack cylinder are widely used in Brazil，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed rack cylinder for customers from Brazil.
We can not just consider the price and ignore the quality when we purchase the rack cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the rack cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the rack cylinder is not required.
The viscosity of the working oil used in the rack cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.
The coordination of the sliding parts of the rack cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.
The meaning of the rack cylinder model marked by the rack cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the rack cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the rack cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.
Hydraulic system schematic diagram, pipeline identification S and L, respectively corresponding nominal diameters? 16S is equivalent to DN12 high-pressure cylinder, and 15L means what?
16S refers to the high pressure series, outer diameter 16x2 steel pipe, the corresponding sleeve nut is M24X1.515L is the low pressure series, the outer diameter of 15x1.5 steel pipe, the corresponding sleeve nut is M22X1.5.
What is the function of the Reza mounted master cylinder?
The role of the Resa-mounted master cylinder is to pump the concrete from the hopper to the delivery pipe and to provide sufficient concrete outlet pressure so that the concrete can reach the specified location.
