 Application:Electric Hydraulic grab Used for loading and unloading bulk cargo such as yellow sand, coal, mineral powder, ore, cement, etc

The electric hydraulic grab hydraulic pump adopts a constant power pump and a hydraulic servo system, and the system pressure changes can effectively control the output of the pump. When the maximum pressure is reached, the flow rate of the pump is extremely low, greatly reducing overflow, energy consumption, and oil temperature to utilize long-term continuous operation, greatly improving production efficiency. The electric hydraulic grab has a simple structure, convenient operation, and can work in various harsh environments.

Electric hydraulic grab opening cycle I:
When the electric motor is running, the hydraulic pump pumps hydraulic oil from the oil tank. When the grab needs to be opened, the hydraulic oil flows through a one-way valve through a pressure pipe to the rod chamber of the oil cylinder. At the same time, the pressure oil opens the return port of the hydraulic control one-way valve, and the oil in the rodless chamber of the oil cylinder flows into the return pipe, which returns to the oil tank through the return filter. As the cylinder piston rod retracts into the cylinder barrel, the grab gradually opens.When the motor is turned off, the one-way valve and hydraulic control one-way valve can lock the oil pressure in the cylinder to prevent the grab from automatically closing.

Electric hydraulic grab closed cycle II:
When the electric motor is running, the hydraulic pump pumps oil into the pressure pipe to operate the electric control box. The hydraulic oil enters the rodless chamber of the oil cylinder through a one-way valve and pressure pipe. At the same time, the pressure oil opens the control oil passage of the hydraulic control one-way valve, allowing the hydraulic oil in the rod chamber of the oil cylinder to flow back to the oil tank through the pressure pipe and hydraulic control one-way valve, through the return pipe and oil filter
