Ghana hydraulic cylinder,supporting cylinder manufacturer,supporting cylinder(Ghana supporting cylinder,produced by Hengyu Group)
supporting cylinder are widely used in Ghana,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed supporting cylinder for customers from Ghana.
When the supporting cylinder is kept, do not pay attention to keeping the oil port open, which will produce the condition of accepting foreign bodies at all times, which is absolutely not allowed. Storage must be filled with anti-rust oil or working oil, and plug.
There are some honeycomb holes in the inner wall of the supporting cylinder, piston or piston rod surface. How is this formed? When we repair the supporting cylinder, we can see that there are some honeycomb holes on the inner wall of the supporting cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the supporting cylinder is targeted to prevent. Is very necessary.
When the supporting 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.
Piston supporting cylinder is widely used in hydraulic transmission. When the supporting cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the supporting cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the supporting cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.
How to remove the air in hydraulic cylinder?
Connected the cylinder to the system, and reciprocating move with full stroke several times, then the air can be eliminated . There is also a clunky method as follows: first remove the rod cavity oil pipe, connect the rodless cavity oil circuit to extend all the cylinders, and then remove the rodless cavity oil pipe, connect the rod cavity oil pipe and withdraw all the cylinders, and then connect the rodless cavity oil pipe, so that there is no air in the cylinder.
What is the safety factor of 25MPa cylinder wall thickness?
Safety factor n can take 3 cylinder material allowable stress [s]=sb/n δ/D=0.08 ~ 0.3 cylinder wall thickness δ=PMAX*D/ (2.3[s]-3PMAX) δ/D≤0.08 cylinder wall thickness δ=PMAX*D/2[s] P < 16MPa, Pmax=1.5Pn; P > 16MPa, Pmax=1.25Pn cold-drawn tube or honing tube is better!
