Portugal hydraulic cylinder,steering cylinder manufacturer,steering cylinder(Portugal steering cylinder,produced by Hebei Hengyu company)
steering cylinder are widely used in Portugal,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed steering cylinder for customers from Portugal.
When the steering 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.
When the steering 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 steering 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 steering cylinder is installed, the piston and the steering cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the steering cylinder head boss is easy to cause scars when it hits the inner surface of the steering cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized steering cylinders, only careful and careful operation can be avoided.
The repair method of the steering cylinder: the repair of the steering cylinder must use brush plating. This is because this repair method can be carried out on site, and the repair effect is good. In this way, loading and transportation can be eliminated to shorten the repair time and improve work efficiency. In addition, the coating obtained by brush plating has good binding force and will not have obvious boundaries. Moreover, the repair surface has high hardness and good wear resistance.
How to deal with the surface degreasing process before spraying paint after cylinder assembly, and what degreasing agent is used?
Cylinder painting, generally using the following process (note: the cylinder is best painted, do not spray powder coating, because the powder coating curing temperature is high, will lead to sealing defects and oil leakage) : Pre-degreasing - degreasing - washing - washing - pickling - washing - washing - table adjustment - phosphating - washing - washing - drying - polishing - spray primer - spray paint degreasing agent generally use neutral or weak alkaline degreasing agent, phosphating liquid generally use zinc phosphating liquid.
What are the standard cylinder models for hydraulic cylinders?
National standard GB/T2348-1993 specifies the hydraulic cylinder inner diameter series, you can check GB/T2348-1993 relevant regulations.
