Estonia hydraulic cylinder,press machine hydraulic cylinder manufacturer,press machine hydraulic cylinder(Estonia press machine hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
press machine hydraulic cylinder are widely used in Estonia,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed press machine hydraulic cylinder for customers from Estonia.
The "O" ring can be used as an auxiliary seal inside the press machine hydraulic cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the press machine hydraulic cylinder, and can be completely sealed.
When using the press machine hydraulic cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the press machine hydraulic cylinder block. If the press machine hydraulic 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 press machine hydraulic cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the press machine hydraulic cylinder, so that the working efficiency of the press machine hydraulic cylinder is reduced.
When purchasing the press machine hydraulic cylinder, try to clarify the following parameters of the press machine hydraulic cylinder: A. press machine hydraulic cylinder diameter, rod diameter, stroke; B. Working pressure or press machine 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 press machine hydraulic cylinder type can be found accurately and quickly.
The material of the sliding part of the press machine hydraulic cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.
How to calculate the cylinder diameter, rod diameter and pressure of the cylinder, and how to output tonnage?
Hydraulic cylinder output force F=PAX10^3(KN) F is the output force (KN), P working pressure (MPa), A is the piston or plunger area of action.
How to distinguish high pressure cylinder and low pressure cylinder?
There is no special definition of the cylinder, the so-called pressure classification refers to the pump low pressure (code L) container 0.1MPa ≤p < 1.6MPa; Medium pressure (code M) container 1.6MPa ≤p < 10.0MPa; High pressure (code H) vessel 10 MPa≤p < 100 MPa; Ultra-high pressure (code U) container p≥100MPa. (1MPa=9.8Kg)
