Korea roller press hydraulic cylinder

(Korea roller press hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)

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

Introduction to roller press hydraulic cylinder:

When purchasing the roller press hydraulic cylinder, try to clarify the following parameters of the roller press hydraulic cylinder: A. roller press hydraulic cylinder diameter, rod diameter, stroke; B. Working pressure or roller press hydraulic cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right roller press hydraulic cylinder type can be found accurately and quickly.

The piston rod and guide sleeve function of the roller press hydraulic cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.

When the roller press hydraulic cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the roller press hydraulic cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the roller press hydraulic cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the roller press hydraulic cylinder can meet the requirements by grinding. However, the life and reliability of this repair roller press hydraulic cylinder are not high.

Under normal circumstances, the roller press hydraulic cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the roller press hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the roller press hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the roller press hydraulic cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the roller press hydraulic cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

Answers to some questions about roller press hydraulic cylinder:

What are the differences between hydraulic cylinder and pneumatic cylinder, what are their advantages and disadvantages?
Hydraulic Cylinder: small body and large force, constant speed and variable speed (easy to change), the adjustment of output is also convenient, and the degree of freedom of transmission is high. However, maintenance costs and installation costs are high, and there is the trouble of mild oil pollution. Pneumatic Cylinder: easy to control, low price, easy access to energy. But the force is small, and can not achieve the effect of stable speed. The gas-liquid pressurized cylinder has the advantages of both of the above: environmental protection and energy saving, easy control, and simple adjustment. However, the output of the trip has certain restrictions, so it is more suitable for short trips, large output, but also environmental protection and energy saving and low configuration of the occasion. Because the pressure used in the pneumatic system is generally in the range of 0.2-1.0Mpa, the cylinder is not suitable for high power component.

Can one hydraulic pump with two cylinders work?
A hydraulic pump with two cylinders will work. Commonly used hydraulic pump types: 1, according to whether the flow can be adjusted can be divided into: variable pump and quantitative pump. The output flow can be adjusted according to the needs of the variable pump, the flow can not be adjusted called quantitative pump. 2, according to the pump structure commonly used in the hydraulic system is divided into: gear pump, vane pump and plunger pump 3 kinds. Gear pump: small volume, simple structure, the cleanliness of the oil requirements are not strict, the price is cheaper; However, the pump shaft is subjected to unbalanced force, serious wear and leakage. Vane pump: divided into double acting vane pump and single acting vane pump. The pump has uniform flow, smooth operation, low noise, higher pressure and volumetric efficiency than gear pump, and more complex structure than gear pump.
