(India single rack cylinder,produced by Hengyu Hydraulic Co., Ltd）

single rack cylinder are widely used in India，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed single rack cylinder for customers from India.

Introduction to single rack cylinder:

The meaning of the single rack cylinder model marked by the single rack cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the single rack cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the single rack cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

The piston rod of the single rack cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

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

The single rack cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the single rack cylinder should pay attention to: the operation should be as far away from the single rack cylinder as possible, to avoid falling objects, knocking, rubbing the single rack cylinder coating. When cleaning the single rack cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the single rack cylinder when the oil temperature exceeds 70 ° C.

Answers to some questions about single rack cylinder:

What are the cylinder manufacturing processes?
Hydraulic cylinder processing process: 1, cylinder: a, material preparation (seamless steel pipe) → inspection (material certificate, etc.) → tempering (outsourcing: Some parts) → car (car round, shelf mouth, boring, flange stop, etc.) → tempered hardness test → welding (welded pipe joint base, flange and other accessories) → boring or honing (rough boring, fine boring, rolling) → car (hole slot or internal and external thread) → fitter (drilling) → inspection → rust prevention storage b, material preparation (forgings) → inspection (material certificate, inspection, etc.) → welding (blank butt welding) → welding inspection → car (rough car) → quality control (outsourcing: some parts) → car (car round, shelf mouth, boring stop, flange stop, etc.)

The pressure gauge of the hydraulic station reaches 20MPa. How many tons of weight can the hydraulic cylinder lift? How to convert?
20Mpa=200kg/cm^2 The weight of the cylinder with a cross-sectional area of 1 square centimeter can be lifted is 200kg, so F=200X3.14X (125/2) ^2 =24531kg =24.5 tons.
