(Ecuador crushing machine hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

crushing machine hydraulic cylinder are widely used in Ecuador，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed crushing machine hydraulic cylinder for customers from Ecuador.

Introduction to crushing machine hydraulic cylinder:

The piston seal of the crushing machine hydraulic cylinder is the main element to prevent leakage in the crushing machine hydraulic cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

crushing machine hydraulic cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the crushing machine hydraulic cylinder is placed for a period of time, the crushing machine hydraulic cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

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

How to repair the crushing machine hydraulic cylinder body when it is damaged: When the crushing machine hydraulic cylinder has trace deformation and shallow tensile marks, the crushing machine hydraulic cylinder is repaired by strong honing process. The heavy honing process can repair crushing machine hydraulic cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the crushing machine hydraulic cylinder can meet the technical requirements.

Answers to some questions about crushing machine hydraulic cylinder:

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.

Why the lifting cylinder falling by itself?
May be there is a pressure relief point. Check and repair the following parts: whether there is oil leakage in the transparent pipe at the top of the cylinder: the cylinder oil seal is broken, and the cylinder and oil seal need to be replaced; No: The multiway valve has pressure relief and needs to be repaired. Maintenance in accordance with routine maintenance items can reduce mechanical failures: 1. Check whether the thermostat works normally. 2, check the transmission shift work is normal. 3. Check the tightness of the fan belt. 4, check whether the diesel tank oil inlet filter is blocked or damaged, and clean or replace the filter. 5. Check and adjust the valve clearance.
