Korea lift cylinder of forklift truck

(Korea lift cylinder of forklift truck,produced by Hengyu Group)

lift cylinder of forklift truck are widely used in Korea,because of excellent temperature resistance,powerful torque,no transmission clearance.So our company has designed lift cylinder of forklift truck for customers from Korea.

Introduction to lift cylinder of forklift truck:

The internal leakage of the lift cylinder of forklift truck is an important indicator to measure the quality of the lift cylinder of forklift truck: the internal leakage of the lift cylinder of forklift truck will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the lift cylinder of forklift truck, so that the lift cylinder of forklift truck can not accurately and stably stop in a certain position of the lift cylinder of forklift truck, so it is one of the main indicators of the lift cylinder of forklift truck.

In use, the lift cylinder of forklift truck should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the lift cylinder of forklift truck.

When the hydraulic oil is not pumped into the lift cylinder of forklift truck, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the lift cylinder of forklift truck to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

When the lift cylinder of forklift truck thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the lift cylinder of forklift truck. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the lift cylinder of forklift truck still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

Answers to some questions about lift cylinder of forklift truck:

Why do two hydraulic cylinders lift out of sync?
There may be several situations (do not know the result of the equipment, may not be accurate) 1, whether the slow one is worn 2, whether there is air in the slow cylinder 3, if the two cylinders are supplied by the same oil port, whether the slow joint is blocked (some processing residue will reach a certain oil port under a certain coincidence condition, This situation will not happen if it is not necessarily good before) 4, the oil seal in the slow cylinder leaks, causing the feed oil to leak from the return oil end. Point 4 is most likely because it is invisible and a technical failure. If it is a dual oil feed (separate oil feed), it is also necessary to check the oil supply system and the oil return system (valve type).

Cylinder pressure calculation formula
The pressure of the cylinder at work is determined by the load, and the pressure of the physical force is equal to the force divided by the area of action (that is, P=F/S). If you want to calculate the output force of the cylinder, you can calculate it according to the formula: Set the radius of the piston (that is, the cylinder) is R (unit mm) the radius of the piston rod is r (unit mm) the working pressure P (unit MPa) the thrust of the cylinder F push =3.14*R*R*P (unit N) The pulling force of the cylinder F pull =3.14* (R*R-r* R) *P (unit N).
