(El Salvador hydraulic cylinder for vehicles,produced by Hengyu Group）

hydraulic cylinder for vehicles are widely used in El Salvador，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed hydraulic cylinder for vehicles for customers from El Salvador.

Introduction to hydraulic cylinder for vehicles:

Repair method of small range wear of oil hydraulic cylinder for vehicles: 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 hydraulic cylinder for vehicles 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 hydraulic cylinder for vehicles, and the phenomenon of "pulling the hydraulic cylinder for vehicles" 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.

If it is found that the hydraulic cylinder for vehicles lubrication is poor or the hydraulic cylinder for vehicles bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the hydraulic cylinder for vehicles, the guide rail and the piston rod have relative movement, if the lubrication is poor or the hydraulic cylinder for vehicles bore is abnormal, it will aggravate the wear and reduce the straightness of the hydraulic cylinder for vehicles center line. In this way, when the piston works in the hydraulic cylinder for vehicles, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the hydraulic cylinder for vehicles first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

The daily inspection of the hydraulic cylinder for vehicles includes: checking the connection of the hydraulic cylinder for vehicles and the pipe joint for leaks. Check the hydraulic cylinder for vehicles rod for leaks. Check the hydraulic cylinder for vehicles connection for leaks. When the hydraulic cylinder for vehicles moves, the work is normal and smooth. Whether the hydraulic cylinder for vehicles has internal leakage.

Answers to some questions about hydraulic cylinder for vehicles:

What are the connection methods of the hydraulic cylinder? The connection modes of the cylinder and the actuator are earring connection, hinge shaft connection, thread connection, etc. The connection modes of tubing and cylinder are threaded connection, flange connection, etc.

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.
