进口防反转长轴深井泵哪家品牌好

进口防反转长轴深井泵Structure: It includes a motor, a motor seat and a pump seat. The motor seat is connected with the motor through the motor connecting plate, the motor seat is fixedly connected with the pump seat, the motor shaft of the motor is connected with the drive shaft through the elastic pin coupling, the drive shaft passes through the fixed bearing seat, the bearing seat contacts the drive shaft through the corresponding bearing, a bearing gland is fixed on the bearing seat, and an anti reverse turntable rotating synchronously with the drive shaft is set above the bearing gland, The lower surface of the anti reverse rotary table is provided with a pin hole, the upper surface of the bearing gland is provided with an arc pin groove corresponding to the pin hole, the depth of the pin groove gradually becomes shallow from one end to the other end until it is flush with the upper surface of the bearing gland, and the anti reverse pin is inserted into the pin hole. It can not only effectively control the shaft reverse rotation and avoid damage caused by reverse rotation, but also it is more convenient to disassemble and replace the bearing without using a specially designed special motor. 进口防反转长轴深井泵The motor has strong interchangeability and is conducive to cost control. characteristic: The long shaft deep well pump is a vertical single suction centrifugal pump. Its impeller is installed below the dynamic water level in the well. The power machine is set on the well. The impeller is driven to rotate in the guide shell through the drive shaft. The water flow is lifted up to the ground through the water transmission pipe along the flow channel between the guide shell and the impeller. When the head is high, a multistage centrifugal pump with multiple impellers in series can be used. 进口防反转长轴深井泵The principle is: The upper part of the bearing gland is provided with an anti reverse turntable rotating synchronously with the drive shaft, the lower surface of the anti reverse turntable is provided with a pin hole, the upper surface of the bearing gland is provided with an arc-shaped pin groove corresponding to the pin hole, the depth of the pin groove gradually becomes shallow from one end to the other end until it is flush with the upper surface of the bearing gland, and the pin hole is inserted with an anti reverse pin which enters and exits the pin groove intermittently with the rotation of the anti reverse turntable. Take clockwise rotation as the positive rotation of the drive shaft as an example. During positive rotation, the anti reverse rotary table rotates clockwise with the drive shaft, and the anti reverse pin enters the pin groove from the deepest point of the pin groove and leaves the pin groove from the shallowest point. In case of reverse rotation, the drive shaft rotates counterclockwise, so that the anti reverse turntable drives the anti reverse pin to rotate counterclockwise, and the anti reverse pin enters the pin groove from the shallowest depth. When the anti reverse pin enters the deepest pin groove, the side wall of the pin groove will prevent the anti reverse pin from continuing to rotate with the anti reverse turntable, thus hindering the reverse rotation. Through the above process, only the shaft reversal can be effectively controlled to avoid damage caused by reversal.
