(Tanzania stroke adjustable cylinder,produced by Hebei Hengyu company）

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

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.

The advantages and disadvantages of the stroke adjustable cylinder: the surface of the stroke adjustable cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the stroke adjustable 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.

Classification of stroke adjustable cylinder: according to the mode of movement it can be divided into linear reciprocating movement type and rotary swing type; According to the effect of liquid pressure, it can be divided into single acting type and double acting type. According to the structure, it can be divided into piston type, plunger type, multistage telescopic sleeve type, pinion and rack type, etc. According to the installation form can be divided into rod, earring, foot, hinge shaft and so on; According to the pressure grade can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.

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.

Answers to some questions about stroke adjustable cylinder:

What factors does the movement speed of the cylinder in the hydraulic system depend on?
The hydraulic system should be the piston movement in the cylinder, and the speed should also be the speed of the piston, according to the piston speed formula: v=4qm/pai*(D^2-d^2) where q is the flow rate of the input hydraulic cylinder, m is the volumetric efficiency of the hydraulic cylinder, D, d is the diameter of the piston and piston rod, because other factors are determined, the movement speed of the cylinder depends on the flow rate.

How to distinguish the size of hydraulic cylinder cavity?
The hydraulic cylinder has a rod cavity and a rodless cavity. The rod cavity is the cavity that the piston rod extends out. The rod cavity is of course small due to the existence of the piston rod. That's just relative.
