GZB high vacuum gear pump relies on the master-driven gear intermeshing the pump body into the suction chamber and the pressure chamber. The oil sucking chamber gradually disengages due to the intermeshing gear teeth, and the working volume of the sealing gradually increases to form a partial vacuum. Therefore, the oil in the oil tank enters the oil sucking chamber through the oil sucking pipe under the effect of the external atmospheric pressure, And with the gear rotation, the oil to the left side of the pressure chamber. On the side of the press area, as the teeth gradually enter into engagement here, the volume of the working chamber is continuously reduced and the oil is squeezed out and delivered from the pressure chamber to the pressure line. When the motor is running, the propulsion device runs at high speed along with the main shaft. The propulsion device is similar to an axial-flow pump, and the rate of evacuation (evacuation) is far greater than the rate of gear engagement and evacuation. With the propulsion of the propulsion device, Interlocking anti-leakage is blocked, the formation of the ultimate vacuum has naturally been greatly improved, at a lower position of the oil is rapidly inhaled pump chamber, and then by the discharge chamber is pressed into the exit. When the oil resistance (pressure) exceeds the set safety pressure, the safety valve is activated, so that oil drain chamber oil back to the suction chamber, so as to keep the pressure does not rise, safety valve overload protection.
