Selection and precautions of hydraulic cylinders for excavators
The hydraulic cylinder of an excavator is one of the important components, which converts hydraulic energy into mechanical energy,
Drive mechanical movement. When purchasing hydraulic cylinders for excavators, the following points should be noted:
1. Size and quality: The size and quality of the excavator hydraulic cylinder should match the model and specifications of the excavator to ensure its normal operation.
2. Pressure and flow rate: The pressure and flow rate of the excavator hydraulic cylinder should match the requirements of the hydraulic system,
To fully utilize the capabilities of the hydraulic system.
3. Sealing performance: The hydraulic cylinder of the excavator has good sealing performance to avoid hydraulic oil leakage or entering the mechanical interior.
4. Durability: The hydraulic cylinder of the excavator has good durability and can withstand long-term heavy load work.
5. Brand and Quality: Choose well-known excavator hydraulic cylinders to ensure their quality and after-sales service
