Finland hydraulic cylinder,trailer hydraulic cylinder manufacturer,trailer hydraulic cylinder(Finland trailer hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
trailer hydraulic cylinder are widely used in Finland,because of long service life,smooth movement,high work efficiency.So our company has designed trailer hydraulic cylinder for customers from Finland.
The advantages and disadvantages of the trailer hydraulic cylinder: the surface of the trailer hydraulic cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the trailer hydraulic cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.
When the trailer hydraulic cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the trailer hydraulic cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.
When the oil pressure of the trailer hydraulic cylinder inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.
When the trailer hydraulic 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.
To achieve the same stroke, which is better, hydraulic cylinder or lead screw?
If there is batch action, then the hydraulic pressure is better. Hydraulic: smooth operation, no lubrication, easy control, high control accuracy (can use proportional or servo system), the key is to manually control, but certainly to support the hydraulic system, for a single action must cost. Maintenance costs are also high. Lead screw: simple structure, easy to achieve, convenient maintenance, but must be lubricated, can not be manual, or manual control is inconvenient. See where it is used, if it is used in high-precision occasions, it must only be hydraulic, because the lead screw has a gap. There are many hydraulic actions, the hydraulic system itself must be prepared, then the use of hydraulic pressure is also very economical.
For a cylinder with a piston diameter of 100mm and a system pressure of 10MPa, what is the thrust?
Thrust is 7850 kg. Piston area A= πR^2=7850 square mm =78.5 square cm 10MPa = 100kg/cm^2 "^2" is square F = A x P =78.5 x 100=7850 kg.
