Republic of Lithuania hydraulic cylinder,stroke adjustable cylinder manufacturer,stroke adjustable cylinder
(Republic of Lithuania stroke adjustable cylinder,produced by Hengyu Hydraulic Cylinder Factory）
stroke adjustable cylinder are widely used in Republic of Lithuania，because of long service life，smooth movement，high work efficiency.So our company has designed stroke adjustable cylinder for customers from Republic of Lithuania.
stroke adjustable cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the stroke adjustable cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the stroke adjustable cylinder. c. The stroke adjustable cylinder seal is extruded, if the O-ring is obviously extruded at the stroke adjustable cylinder seal, replace the stroke adjustable cylinder seal.
The stroke adjustable cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the stroke adjustable cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The stroke adjustable cylinder is basically composed of stroke adjustable cylinder and stroke adjustable cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.
In the process of using the stroke adjustable cylinder, sometimes such a problem will occur, the stroke adjustable cylinder can not act immediately after the instruction of the stroke adjustable cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil stroke adjustable cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.
The stroke adjustable cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure stroke adjustable cylinder can use 20 steel pipe, and the high pressure stroke adjustable cylinder can use 45 steel pipe.
In a hydraulic system, a hydraulic pump has many hydraulic cylinders and hydraulic motors, and these executive components do not coordinate their actions with each other.
A load-sensitive variable pump can be used if these components sometimes need to work simultaneously and the power required is large. The required flow is distributed by the multi-way reversing valve, and the required flow and pressure changes are automatically adjusted by the hydraulic pump. Pressure reducing valves can be used for particularly low pressure circuits. Because you execute more components, the use of quantitative pump will cause a waste of energy, the system heat is large, not suitable.
The difference between the overall cylinder and the separate cylinder of the truck?
The whole cylinder is cast in one piece, and such a cylinder generally does not leak oil. Split cylinder refers to two welded, easy to leak oil in the welding place, resulting in damage to the cylinder, or its body can not get up, many people do not use this kind of cylinder now.
