(Egypt shearing machine cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to shearing machine cylinder:

When the initial action of the shearing machine cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the shearing machine cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

The viscosity of the working oil used in the shearing machine 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.

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 main role of the shearing machine cylinder: the shearing machine cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the shearing machine cylinder realizes reciprocating motion. The structure of the shearing machine cylinder has three categories: piston shearing machine cylinder, plunger shearing machine cylinder, swing shearing machine cylinder, piston shearing machine cylinder and plunger shearing machine cylinder to achieve reciprocating linear motion, output speed and thrust, swing shearing machine cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the shearing machine cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The shearing machine cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

Answers to some questions about shearing machine cylinder:

Why the lifting cylinder falling by itself?
May be there is a pressure relief point. Check and repair the following parts: whether there is oil leakage in the transparent pipe at the top of the cylinder: the cylinder oil seal is broken, and the cylinder and oil seal need to be replaced; No: The multiway valve has pressure relief and needs to be repaired. Maintenance in accordance with routine maintenance items can reduce mechanical failures: 1. Check whether the thermostat works normally. 2, check the transmission shift work is normal. 3. Check the tightness of the fan belt. 4, check whether the diesel tank oil inlet filter is blocked or damaged, and clean or replace the filter. 5. Check and adjust the valve clearance.

How to remove the cylinder correctly?
(1) Before disassembling the hydraulic cylinder, the hydraulic circuit should be depressurized. Otherwise, when the tubing joint connected with the cylinder is loosened, the high-pressure oil in the circuit will be quickly ejected. The hydraulic circuit of the hydraulic press should first loosen the hand wheel or pressure regulator screw at the relief valve, so that the pressure oil is unloaded, and then block the power supply or block the power source to stop the operation of the hydraulic equipment. (2) When disassembling, it should prevent damage to the top thread of the piston rod, the oil thread, the appearance of the piston rod, the inner wall of the cylinder liner, etc. In order to prevent the piston rod and other slender parts from twisting or deformation, the use of cushion wood support balance when placed. (3) Disassemble in order.
