Kuwait hydraulic cylinder,baling press cylinder manufacturer,baling press cylinder(Kuwait baling press cylinder,produced by Hengyu Hydraulic Cylinder Factory)
baling press cylinder are widely used in Kuwait,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed baling press cylinder for customers from Kuwait.
If the baling press 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 baling press cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow baling press cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the baling press cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the baling press cylinder includes the leakage caused by excessive wear of the baling press 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 baling press cylinder, and the phenomenon of "pulling the baling press cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.
When the baling press cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the baling press cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.
If the baling press 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.
baling press cylinder piston rod material selection and requirements: ① piston rod is usually made of 45 steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. The piston rod is generally designed as a baling press cylinder, if the diameter is larger, the hollow piston rod can be used. Made of No. 45 seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the working surface of the rod can be plated with hard chromium. ⑥ The piston rod and the end cap are guided by H8 ' baling press cylinder piston rod industry standard: piston rod diameter series of national recommended standard GB/T2348-1993. Piston rod thread size series standard GB/T2350-1980. Please refer to execute. There is no industry standard for piston rods Both the baling press cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The baling press cylinder mainly outputs linear motion and force. The baling press cylinder has a variety of forms, according to the different characteristics of its mechanism it can be divided into piston type, plunger type and swing type three categories, according to the mode of action he can be divided into single action and double action. Piston baling press cylinder, plunger baling press cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger baling press cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.
How to store hydraulic cylinder?
After cleaning the hydraulic cylinder with diesel or kerosene, apply lubricating oil and wrap it in oil paper, preferably in a wooden box, and store it in a dry and non-corrosive environment. The outer surface and inner surface of the hydraulic cylinder are sprayed with diesel oil, and the inner layer is covered with cloth and the outer coating of anti-rust oil is good. Put it in a dry place, clean it with diesel oil, and then apply a layer of anti-rust inside and outside the butter.
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.
