QT series internal gear pump内啮合齿轮泵
 
High Pressure Low Noise and energy saving with Servo system
The gear profile of this straight conjugate internal gear pump is straight line, and the gear ring profile is conjugate line. So there is hardly any oil trapping area when working, which greatly reduces the pressure pulsation of this pump, and it has very low noise. Because of its simple structure and compulsory lubrication of sliding surface, there is almost no direct contact between components, and it almost reaches the ideal state of never wearing.
It has compact structure, high volume efficiency, insensitive to medium pollution, small fluctuation of flow and pressure, very low noise and long service life. It is widely used in hydraulic systems of mining machinery, precision machine tools, engineering machinery, plastic machinery, metallurgical machinery, petrochemical machinery and other industries, such as injection molding machine, hydraulic press, die-casting machine, shearing machine, pipe bending machine, vulcanizing machine, ceramic machinery, brick press, forklift, testing machine, etc., and has developed rapidly.
Its comprehensive performance ranks first among all types of hydraulic pumps, and its indexes far exceed those of other types of hydraulic pump, such as external meshing gear pump, piston pump, vane pump and screw pump.
All practices have proved that this internal gear pump is the representative work of servo energy saving hydraulic pump. If it is equipped with servo drive motor, the optimized gear design makes it maintain low rotation speed when hydraulic system must keep working pressure, greatly reducing power consumption, It has advantage of high efficiency, environmental protection and energy saving.
