Australia retractable cylinder

(Australia retractable cylinder,produced by Hengyu Hydraulic Cylinder Factory)

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

Introduction to retractable cylinder:

The advantages and disadvantages of the retractable cylinder: the surface of the retractable cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the retractable cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.

The retractable cylinder should be vented: when the retractable cylinder is installed or parked for a long time to work again, the air will penetrate into the retractable cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the retractable cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the retractable cylinder, the oil is best entered and discharged from the highest point of the retractable cylinder. retractable 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.

retractable cylinder and hydraulic station selection: Select the type and structure of the retractable cylinder according to the operation requirements of the main engine. According to the external load force borne by the retractable cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the retractable cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the retractable cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the retractable cylinder, the diameter of the piston and the piston rod.

If the retractable cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the retractable cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow retractable cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the retractable cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the retractable cylinder includes the leakage caused by excessive wear of the retractable cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and retractable cylinder, and the phenomenon of "pulling the retractable cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

Answers to some questions about retractable cylinder:

What are the main dimensions of the cylinder?
The main dimensions of the cylinder include: cylinder inner diameter, piston cylinder diameter, cylinder length, cylinder wall thickness, stroke, installation distance, etc.

What are the problems that cause hydraulic cylinder shaking?
1, the oil supply is not smooth, the hydraulic oil filter is half blocked. 2. The oil level in the oil storage tank is lower than the minimum oil level. 3, there is air in the hydraulic system. 4, the supply oil pump is damaged or not working properly. 5, the hydraulic oil is not replaced for a long time.
