(Poland stroke adjustable cylinder,produced by Hengyu Hydraulic Co., Ltd）

stroke adjustable cylinder are widely used in Poland，because of simple structure and reliable operation，powerful torque，clever hydraulic energy conversion.So our company has designed stroke adjustable cylinder for customers from Poland.

Introduction to stroke adjustable cylinder:

If the stroke adjustable 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 stroke adjustable cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow stroke adjustable cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the stroke adjustable cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the stroke adjustable cylinder includes the leakage caused by excessive wear of the stroke adjustable 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 stroke adjustable cylinder, and the phenomenon of "pulling the stroke adjustable cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

stroke adjustable cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the stroke adjustable cylinder head itself is the guide sleeve of the piston rod, the stroke adjustable cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the stroke adjustable cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

The main role of the stroke adjustable cylinder: the stroke adjustable cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the stroke adjustable cylinder realizes reciprocating motion. The structure of the stroke adjustable cylinder has three categories: piston stroke adjustable cylinder, plunger stroke adjustable cylinder, swing stroke adjustable cylinder, piston stroke adjustable cylinder and plunger stroke adjustable cylinder to achieve reciprocating linear motion, output speed and thrust, swing stroke adjustable cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the stroke adjustable cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The stroke adjustable cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

If the stroke adjustable cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.

Answers to some questions about stroke adjustable cylinder:

What is the thin cylinder used for?
The principle is no different from ordinary cylinders, that is, the installation space is small, the formation is small, and it is suitable for some special occasions. For example, the space is compact and the place of small travel is used.

What is the role of the cylinder on the plastic mold? The oil cylinder plays a great role in the mold, one is that the core distance is very large, or because of the mechanism of the product, only the oil cylinder is reasonable or more cost saving. Let the side core be extracted before opening the mold. Hot runner is mainly based on the product, sometimes customers require to use hot runner, the price is more expensive, but there are many benefits. It can save raw materials and shorten the molding cycle.
