Deep well water pump detection content

Deep well water pump detection content contains those points
    Deep well water pump is characterized by the outer cylinder and bushing in the ground assembled and connected to the bottom of the tubing first into the well, and then put the fixed valve, and finally the plunger connected to the lower end of the sucker rod into the pump.
    1. Observation tube pump, tube pump structure can be divided into a combination of pumping pump and the whole pump. Combination pump: from the external work tube and set in the outer cylinder in the cylinder, plunger (plunger inside and downstream moving magic) and fixed Vale composition. Whole cylinder pumping pump: by the pump, plunger (plunger inside and downstream moving magic) and fixed Vale composition. It has the following advantages in combination with the combined pumping pump: the structure is simple, light weight, no bushing, no bushing misalignment occurs during transport and downhole operation, the length of the pump can be made longer and can be made to adapt to long stroke pump
    2. Observation rod pump, rod pump is the whole pump is assembled on the ground and then connected to the bottom of the sucker rod, the whole through the tubing into the pre-installed in the tubing on the pre-set position with a reed cylinder. It is characterized by the fact that the pump does not need to start the tubing and the pump is convenient. The structure is complicated and the manufacturing cost is high. The pump diameter under the same tubing diameter is smaller than that of the tube pump. Therefore, the rod pump for the pump under the depth of the larger, but the lower yield of the well.
    3. Observation of submersible well pump downhole unit, including submersible motor, protector, separator and multi-stage centrifugal pump. One submersible motor is a two-pole, three-phase squirrel cage asynchronous induction motor. Protector is the use of well fluid and motor oil density difference, to prevent the shaft into the motor caused by a short circuit and burn the motor device. The oil and gas separator separates the free gas to prevent and reduce the gas into the pump, so that the multi-stage centrifugal pump can work properly. Multistage centrifugal pumps gradually increase the pressure and velocity of the well fluid to obtain a certain lift and lift it to the ground.
