(Sri Lanka spring return cylinder,produced by Hengyu Hydraulic Co., Ltd）

spring return cylinder are widely used in Sri Lanka，because of clever hydraulic energy conversion，excellent temperature resistance，simple structure and reliable operation.So our company has designed spring return cylinder for customers from Sri Lanka.

Introduction to spring return cylinder:

The oil spring return 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.

If it is found that the spring return cylinder lubrication is poor or the spring return cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the spring return cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the spring return cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the spring return cylinder center line. In this way, when the piston works in the spring return cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the spring return cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

Because of the slightly complex structure of the buffer spring return cylinder, sometimes there will be problems, such as when the spring return cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

Under normal circumstances, the spring return cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the spring return cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the spring return cylinder and the end cover, the piston and the piston rod, the piston and the spring return cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the spring return cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

Answers to some questions about spring return cylinder:

What is the difference between single acting hydraulic cylinder and double acting hydraulic cylinder?
Single action hydraulic cylinder is a single direction force work, the return of the plunger depends on itself or the weight of the mechanism to return. The double acting hydraulic cylinder is mainly different from the extension and retraction of the piston (the thrust and tension of the saying), which are all operated by the action of liquid pressure.

What is the reason why the hydraulic cylinder is not good at lifting?
There may be several situations 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).
