(500 tons hydraulic press cylinder,produced by Hengyu Hydraulic Cylinder Factory）

500 tons hydraulic press cylinder are widely used ，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed 500 tons hydraulic press cylinder for our customers.

Introduction to 500 tons hydraulic press cylinder:

The 500 tons hydraulic press cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure 500 tons hydraulic press cylinder can use 20 steel pipe, and the high pressure 500 tons hydraulic press cylinder can use 45 steel pipe.

When the hydraulic oil is not pumped into the 500 tons hydraulic press cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the 500 tons hydraulic press cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

500 tons hydraulic press cylinder piston rod material introduction: In general, we use 45 steel to produce 500 tons hydraulic press cylinder piston rod. It has a large impact force when it is used, and some good performance steel are also used in the heavy load transmission. In order to have enough work intensity when using, and can ensure normal use, this is still more critical to have a detailed understanding of the material.

Causes and countermeasures of oil 500 tons hydraulic press cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the 500 tons hydraulic press cylinder will lead to premature wear of the piston seal, replace the piston seal; If the 500 tons hydraulic press cylinder is visibly scarred, the 500 tons hydraulic press cylinder must be replaced. It can be pressurized at one end of the 500 tons hydraulic press 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 500 tons hydraulic press cylinder piston drift may not come from the 500 tons hydraulic press cylinder, the above method to determine the 500 tons hydraulic press cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

Answers to some questions about 500 tons hydraulic press cylinder:

What should we pay attention to when using the cylinder?
When using the cylinder, we should pay attention to the environment and temperature in which it is located as follows: 1. Before working, the hydraulic cylinder must carry out several reciprocating movements under low pressure (greater than the starting pressure), and work normally after removing the gas in the cylinder. 2. Precautions when removing the hydraulic cylinder: ① The pressure in the hydraulic circuit is reduced to zero before disassembly. ② The screw thread at the top of the piston rod should be prevented from damage when disassembling. ③ Due to the different structure and size of the hydraulic cylinder, the order of disassembly is also slightly different. Generally, the fastening bolt of the end cover should be loosened first. Internal card chain card key application special tools.

Where's the hydraulic cylinder bleed valve?
There is a vent hole at the top of the cylinder next to the intake pipe. Generally, it can be used, and the air in the cylinder can be naturally drained after several moves.
