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

shearing machine cylinder are widely used in Switzerland，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 Switzerland.

Introduction to shearing machine cylinder:

The shearing machine cylinder is not the same as the shearing machine cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the shearing machine cylinder can not be used as a high-power power component, but the shearing machine cylinder can be used as a relatively large power component, or the shearing machine cylinder system can be used.

The daily inspection of the shearing machine cylinder includes: checking the connection of the shearing machine cylinder and the pipe joint for leaks. Check the shearing machine cylinder rod for leaks. Check the shearing machine cylinder connection for leaks. When the shearing machine cylinder moves, the work is normal and smooth. Whether the shearing machine cylinder has internal leakage.

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 pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the shearing machine cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

Answers to some questions about shearing machine cylinder:

How to choose cylinder size, pump type, motor power for a 30-ton press?
30 tons = 30,000 kg. It is expected to use a 16 mpa oil pump, then the cylinder area =30000/(160x3.14) and then square, the cylinder bore is 150 mm. Calculated at 500 mm travel per minute, the flow rate per minute is :0.75^2x3.14x5=8.8 liters/minute. Motor power =8.8x16/60=2.355. A 9 L/min, 16 mpa pump is available. Piston diameter 150 mm cylinder. 3 kW motor.

What does cylinder hob125*100 mean?
HOB is a series of hydraulic cylinder products, the use of pressure 14MPA, tie rod structure. 125 refers to the diameter of the cylinder and 100 refers to the stroke. The unit is millimeters.
