3010060510 Original Loader Accumulator for ZW370-6

Part number 3010060510 is an original hydraulic accumulator provided by Hitachi for the ZW370-6 large wheel loader. This part is an original Japanese accessory with complete label and bar code. It is packed in protective foam to ensure safe transportation. Accumulator is the core energy storage and buffering component of hydraulic braking system or pilot hydraulic system. Its universal model mainly covers the ZW370-6 model, which is also applicable to large loaders of the ZW330-6 and ZW390-6 series with similar hydraulic system designs. It is strictly prohibited to use accumulator models that do not match or have not been certified, in order to avoid brake failure, system pressure fluctuations, or safety accidents.

This product is a piston type hydraulic accumulator, with a black smooth cylindrical shell made of high-strength alloy steel as the main body, and precision machined flat end caps at both ends. One side of the shell is integrated with an inflation valve, usually equipped with a dust cap, for pre charging high-pressure nitrogen gas. Inside the accumulator, a floating piston completely isolates the nitrogen gas in the upper chamber from the hydraulic oil in the lower chamber. Its core function is to store hydraulic energy and release it quickly when the system needs it; Absorb the pulsation of the pump and the pressure shock of the system; Provide emergency brake pressure when the engine is turned off. The information on the label should include working pressure, volume, serial number, and safety warning. Typical technical parameters include a nominal volume of 1-4 liters, a maximum working pressure of 20-35MPa, and a pre filled nitrogen pressure of approximately 60-70% of the system's minimum working pressure. The working temperature range is -20 ℃ to+80 ℃.

Inspection cycle: Every 500 working hours or every 6 months, check the accumulator for oil leakage, and the casing for corrosion or physical damage. Every 2000 working hours or annually, professional service personnel should use specialized instruments to detect the pre filled nitrogen pressure. If the pressure drops by more than 10% of the initial value, nitrogen should be replenished. Installation points: 1 Vertical installation, with the air valve end facing upwards; 2. Use a torque wrench to tighten the oil circuit joint according to the manual's specified torque (usually 100-200 N · m, depending on the interface size); 3. Before initial use or after maintenance, slowly pressurize the system and check for leaks at all connections. Fault manifestation: If the brake pedal is weak, the system pressure fluctuates violently, or the temperature of the accumulator housing rises abnormally, it may indicate damage to the accumulator bladder, loss of pre charge pressure, or gas leakage.
