Puerto Rico hydraulic cylinder,lift cylinder of forklift truck manufacturer,lift cylinder of forklift truck

(Puerto Rico lift cylinder of forklift truck,produced by Hengyu Hydraulic Cylinder Factory）

lift cylinder of forklift truck are widely used in Puerto Rico，because of no need for deceleration device，long service life，smooth movement.So our company has designed lift cylinder of forklift truck for customers from Puerto Rico.

Introduction to lift cylinder of forklift truck:

When the lift cylinder of forklift truck is in use, ensure that the lift cylinder of forklift truck and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.

When producing oil lift cylinder of forklift trucks, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

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.

The lift cylinder of forklift truck should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the lift cylinder of forklift truck should pay attention to: the operation should be as far away from the lift cylinder of forklift truck as possible, to avoid falling objects, knocking, rubbing the lift cylinder of forklift truck coating. When cleaning the lift cylinder of forklift truck, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the lift cylinder of forklift truck when the oil temperature exceeds 70 ° C.

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).

Can the hydraulic oil in the cylinder return to the tank?
Yes, there is a way, for example, first remove the cylinder from the machine, and then connect the two pipes on the cylinder, so that the cylinder piston rod is completely retracted into the cylinder, at this time, the piston is with the bottom, and the rear chamber is almost no oil, and then screw off the joint at the end of the front chamber by the hydraulic station, and put it in an empty bucket. Finally, insert the gas pipe into the oil port of the rear chamber. Open the air source, and then the rod will run out, and you'll drain the hydraulic oil from the end of the rod, which requires a source of air on site.
