Peru hydraulic cylinder,shearing machine cylinder manufacturer,shearing machine cylinder(Peru shearing machine cylinder,produced by Hengyu Hydraulic Co., Ltd)
shearing machine cylinder are widely used in Peru,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 Peru.
The internal leakage of the shearing machine cylinder is an important indicator to measure the quality of the shearing machine cylinder: the internal leakage of the shearing machine cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the shearing machine cylinder, so that the shearing machine cylinder can not accurately and stably stop in a certain position of the shearing machine cylinder, so it is one of the main indicators of the shearing machine cylinder.
When using the shearing machine cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the shearing machine cylinder block. If the shearing machine cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the shearing machine cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the shearing machine cylinder, so that the working efficiency of the shearing machine cylinder is reduced.
When the shearing machine cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.
The piston rod of the shearing machine 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.
Is rubber or polyurethane better for V-ring of hydraulic cylinder?
The hydraulic cylinder V-type seal ring is better with polyurethane, and chlorine rubber is used for various chemicals and high temperatures, especially when there are wear-resistant requirements, polyurethane rubber is needed. But the price of polyurethane rubber is much more expensive than the price of rubber. However, the V-ring material is most commonly used in nitrile and neoprene rubber, and natural rubber is used for sealing water and air. Butyl rubber is used for non-combustible hydraulic fluids and phosphate ester hydraulic fluids. The advantage is that the price is cheaper than the polyurethane material, and the disadvantage is that it is not wear-resistant and the anti-aging property is relatively poor.
Hydraulic cylinder application areas?
1, in the machine tool industry, 85% of the machine tool transmission system adopts hydraulic transmission and control. Such as grinding machine, milling machine, planer, broaching machine, press, shearing machine, and combined machine tools. 2, in the metallurgical industry, electric furnace control system, rolling mill control system, open furnace charging, converter control, blast furnace control, strip deviation and constant tension device are all using hydraulic cylinders. 3, in the construction machinery, the general use of hydraulic transmission, such as excavators, tire loaders, truck cranes, crawler bulldozers, tire cranes, self-propelled scrapers, graders and vibration rollers. 4, in agricultural machinery, the use of hydraulic cylinders is also widely used, such as combine harvesters, tractors and so on.
