After the F3-V10-1S6S-1C20 circulating pump is started, the oil pumps supplies oil to the system at full flow, and also fills the accumulator with oil. When the oil pressure reaches the system's set pressure of 14Mpa, the high-pressure oil pushes the control valve on the constant pressure valve, and the control valve operates the variable of the pump. The control valve operates the variable mechanism of the pump to reduce the output flow of the pump. When the output flow of the pump is equal to the oil flow of the system, the variable mechanism of the pump is maintained at a certain position. When the system needs to increase or decrease the oil consumption, the pump will automatically change the output flow. Maintain the system oil pressure at 14Mpa. The two pumps are arranged under the oil tank to ensure a positive suction head of the oil pump.
1. The inlet flow path of this circulating pump is designed to provide uniform oil acceleration, so it has better filling characteristics, especially at low inlet pressures.
2. They have been proven to work in harsh environments.
3. The efficient design of the circulating pump reduces the cost per horsepower.
4. High flow, pressure and speed capabilities enable these pumps to meet the hydraulic circuit needs of many modern machinery.
