Belgium hydraulic cylinder,tailplate hydraulic cylinder manufacturer,tailplate hydraulic cylinder(Belgium tailplate hydraulic cylinder,produced by Hengyu Group)
tailplate hydraulic cylinder are widely used in Belgium,because of high work efficiency,long service life,smooth movement.So our company has designed tailplate hydraulic cylinder for customers from Belgium.
tailplate hydraulic 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 tailplate hydraulic 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 ' tailplate hydraulic 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 tailplate hydraulic cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The tailplate hydraulic cylinder mainly outputs linear motion and force. The tailplate hydraulic 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 tailplate hydraulic cylinder, plunger tailplate hydraulic cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger tailplate hydraulic cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.
The tailplate hydraulic cylinder requires that the filtration accuracy of the system is not less than the 80um, and the oil pollution should be strictly controlled, the oil should be kept clean, the performance of the oil should be checked regularly, and the necessary fine filtration and replacement of new working oil should be carried out.
Repair method of small range wear of oil tailplate hydraulic cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.
If the seal of the tailplate hydraulic cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material 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 tailplate hydraulic cylinder, and the phenomenon of "pulling the tailplate hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.
What is the cause of the sound of the excavator arm cylinder?
Hydraulic excavator cylinder includes boom cylinder, bucket rod cylinder and bucket cylinder, four cylinders. The sound of boom cylinder may be the wear of hydraulic cylinder block bushing, piston rod bushing and shaft pin. The main reason: poor lubrication, followed by improper clearance in the assembly process. Countermeasures: (1) Strictly lubricate each shaft pin at least once every 8 hours when the excavator is initially used for 100 hours and under harsh conditions; In other working conditions, lubricate each pin at least once every 50 hours. (2) If the lubricating oil passage is found to be blocked, it must be stopped for rectification. (3) Require assembly, replacement of all parts of the shaft pin, bushing strictly comply with the assembly testing standards and operating procedures.
What is the cause of sound and vibration when the hydraulic cylinder is under load?
The main reason 1) may be that the load machinery has stuck phenomenon, and the resistance is large. 2) The hydraulic oil is not enough, or the filter is blocked by dirty things, and the oil is flooded. 3) There is a problem with the pump.
