PC300-8 Komatsu Excavator Parts Accumulator 22U-60-21330

PC300-7,PC400-7,PC200-7,PC300-8,PC200-8 PC200LC-8 Energy ACCUMULATOR

Accumulator 22U-60-21330 is used for Komatsu PC300-8 Excavator , The excavator is equipped with accumulator in the control oil circuit, which is a device for storing and controlling oil pressure.The accumulator is installed between the main pump and the PPC valve.Its function is to maintain the stability of control oil pressure and when the engine stop, can still put down the working device, to ensure the safety of the machine. Open the main valve cover and look down to see the accumulator. The accumulator contains a skin that holds the gas from the plug and isolates it from the hydraulic fluid. Diaphragm accumulator is a kind of energy storage device in hydraulic pneumatic system.Compared with similar products, the biggest characteristic of diaphragm accumulator is easy to carry weight, easy to install and easy to promote, high sensitivity, simple structure and easy maintenance, and low pressure pulsation elimination effect is significant, so it plays an important role in various industries.Diaphragm type accumulator can be generally divided into welding type, thread type two.The welding structure is simple and the cost is low.The threaded type can replace the diaphragm and improve the utilization of the accumulator.

PC200-8 PC200-7 Excavator Parts Accumulator 22U-60-21330

Working Process of accumulators

1. After the engine is started, the gas in the leather chamber is compressed by the oil pressure of the main pump in the chamber after the pressure is reduced by the self-pressure reducing valve

2. After the engine stops, the gas in the skin continues to be compressed.

3. At this time, after the PPC valve is operated, the air bag expands depending on the pressure of indoor gas. The oil in the room drives the main control valve to work as the control pressure oil, and the working device moves down under the action of self-weight.

PC200-7 excavator solenoid valve accumulator 22U-60-21330

The accumulator is filled with high-pressure nitrogen, which can be dangerous if handled the wrong way.
Observe the following precautions
• do not drill holes in accumulators or burn them with flame.
• do not weld any bump on the accumulator.
• contact komatsu dealer when handling accumulators that require venting from the accumulator.

Fault phenomenon: after the engine is closed, the joystick moves to the "down" position of the working device, and the working device does not move.
Inspection results: nitrogen leakage in the accumulator
Fault analysis: the air in the accumulator is missing. After the engine starts, the skin is compressed due to the oil pressure in room B, but the air in room A is not compressed.
The oil entering chamber B cannot be used as the control pressure oil to push the main control valve, so operate the control valve
Put not to move.
Fault handling: replace the accumulator.
