Korea hydraulic cylinder,shearing machine cylinder manufacturer,shearing machine cylinder

Korea shearing machine cylinder

(Korea shearing machine cylinder,produced by Hengyu Hydraulic Cylinder Factory)

shearing machine cylinder are widely used in Korea,because of no need for deceleration device,long service life,smooth movement.So our company has designed shearing machine cylinder for customers from Korea.

Introduction to shearing machine cylinder:

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

Disassembly shearing machine cylinder: When disassembly shearing machine cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the shearing machine cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the shearing machine cylinder.

If the seal of the shearing machine cylinder is softened and sticky, it may be that the seal is incompatible with the hydraulic oil or the nearby lubricating oil, replace the appropriate seal; If the seal becomes hard and loses elasticity, most of it is because the ambient temperature is too high (more than 80 ° C), make appropriate temperature insulation protection or replace the high temperature seal.

The wear of the hard chromium plating layer of the shearing machine cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.

Answers to some questions about shearing machine cylinder:

How big is the pump and motor for 20 tons of hydraulic cylinder?
According to the working pressure of 25 mpa estimate, the cylinder should use 100mm bore, 63mm piston rod, stroke 40mm. According to 30 reciprocating calculation, the flow rate is about 25 liters/minute. The motor power is 11 kW, want to be cheap, use 25SCY14-1B oil pump can be.

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.
