accumulator hydraulic cylinder are widely used in Greece，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed accumulator hydraulic cylinder for customers from Greece.

Introduction to accumulator hydraulic cylinder:

The accumulator hydraulic cylinder should be vented: when the accumulator hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the accumulator hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the accumulator hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the accumulator hydraulic cylinder, the oil is best entered and discharged from the highest point of the accumulator hydraulic cylinder. accumulator hydraulic cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

The oil accumulator hydraulic cylinder is a part of the hydraulic system, in the hydraulic system, to reasonably design the heat dissipation system, to prevent the oil temperature is too high is the key to keep the hydraulic oil temperature normal. The temperature of the system should be kept in a suitable range to reduce the energy released when the bubble bursts. While not affecting the normal circulation of the coolant, a certain amount of anti-corrosion additives can be appropriately added to inhibit rust. When operating the hydraulic system, we should strive to be stable, not too fast, too strong, and try to reduce the impact of hydraulic oil on hydraulic components.

In use, the accumulator hydraulic cylinder 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 accumulator hydraulic cylinder.

The accumulator hydraulic cylinder is mainly composed of body, piston, piston rod, accumulator hydraulic cylinder head, accumulator hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the accumulator hydraulic cylinder into two chambers, and moves reciprocally in the accumulator hydraulic cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the accumulator hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the accumulator hydraulic cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the accumulator hydraulic cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the accumulator hydraulic cylinder bottom and the accumulator hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the accumulator hydraulic cylinder The working medium of the accumulator hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; accumulator hydraulic cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the accumulator hydraulic cylinder: The buffer structure of the accumulator hydraulic cylinder is to prevent the piston from colliding with the accumulator hydraulic cylinder head at the end of the stroke.

Answers to some questions about accumulator hydraulic cylinder:

What is hydraulic cylinder internal leakage and external leakage?
The internal leakage of the hydraulic cylinder refers to the leakage of the piston head seal of the double-acting cylinder, and the leakage occurs inside the cylinder; The external leakage refers to the leakage phenomenon between the cylinder head (or cylinder guide sleeve) and the plunger rod (or piston rod) and the seal between the guide sleeve and the cylinder block, and the oil in the hydraulic cylinder leaks to the outside.

What hydraulic valve is used to control a cylinder back and forth?
Direction valve is available. Direction valve includes electromagnetic directional valve, manual directional valve, check valve, hydraulic control check valve, the specific choice of which direction valve, you need to see the use of conditions.
