(Australia stroke adjustable cylinder,produced by Hengyu Group）

stroke adjustable cylinder are widely used in Australia，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed stroke adjustable cylinder for customers from Australia.

Introduction to stroke adjustable cylinder:

When the stroke adjustable cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the stroke adjustable cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil stroke adjustable cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical stroke adjustable cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the stroke adjustable cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

Causes and countermeasures of oil stroke adjustable cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the stroke adjustable cylinder will lead to premature wear of the piston seal, replace the piston seal; If the stroke adjustable cylinder is visibly scarred, the stroke adjustable cylinder must be replaced. It can be pressurized at one end of the stroke adjustable cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most stroke adjustable cylinder piston drift may not come from the stroke adjustable cylinder, the above method to determine the stroke adjustable cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

When producing oil stroke adjustable cylinders, 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 difference between the integral stroke adjustable cylinder and the split stroke adjustable cylinder: The integral stroke adjustable cylinder and the split stroke adjustable cylinder in the stroke adjustable cylinder are two different stroke adjustable cylinders, and they are very different. The whole stroke adjustable cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split stroke adjustable cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and stroke adjustable cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

Answers to some questions about stroke adjustable cylinder:

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).

Hydraulic cylinder performance requirements?
Hydraulic cylinder performance requirements: hydraulic cylinder is the hydraulic system to achieve energy transfer, conversion and control of the working medium, in addition, it is also responsible for the lubrication of the system, rust prevention, corrosion prevention and cooling. The performance of hydraulic oil will make the system flexible, accurate and reliable. Hydraulic performance requirements are determined according to the design parameters of the hydraulic system, operating conditions, the structure of the hydraulic pump and the working environment. Appropriate viscosity and good viscosion-temperature performance Viscosity is an important performance indicator of hydraulic pressure, which has an important impact on the smooth operation of the hydraulic system and the friction parts. The low temperature performance of hydraulic oil includes three aspects: low temperature flow, low temperature start-up and low temperature pumping.
