Product Introduction:
The 860570937 is a hydraulic accumulator used in the XCMG XE370 series excavator. It is a maintenance component within the machine's hydraulic system, designed to store pressurized hydraulic fluid and dampen pressure fluctuations during operation.
1. Installation Location
This accumulator is installed within the excavator's hydraulic circuit. Based on the XE370CA hydraulic system layout, accumulators are typically mounted on the main control valve block or along the main hydraulic lines. The XE370CA has a hydraulic oil tank capacity of 320 L and operates at a working pressure of approximately 18 MPa in certain modes.
2. Function
The accumulator stores hydraulic energy under pressure and releases it when needed, helping to stabilize system pressure, absorb pressure spikes and shock loads, and provide emergency pressure reserve. This contributes to smoother operation and reduced wear on hydraulic components.
3. Maintenance and Service
The accumulator is a sealed pressure vessel and is not user-serviceable. Before any service or removal, the hydraulic system must be fully depressurized. The XE370CA operation manual specifies releasing hydraulic pressure by lowering the work equipment to the ground, shutting off the engine, turning the key to ON, placing the safety lock lever in the "open" position, and operating the control levers to release residual pressure. Do not attempt to disassemble or puncture the accumulator. If a fault is suspected, replacement with an identical unit is recommended.
4. Important Notes
Always verify the part number 860570937 matches the original specification for the specific XE370 model variant (e.g., XE370CA, XE370G). Accumulators contain pressurized gas and fluid; improper handling can cause serious injury. Only qualified personnel should perform service.
