Deep well pump test content

    The deep well pump is characterized in that the outer cylinder and the bushing are assembled on the ground and connected to the lower part of the oil pipe first into the well, and then put into the fixed valve, and then the plunger is connected to the lower end of the sucker rod column and into the pump.

    1. Observe the tube pump. The tube pump can be divided into a combination pump and a whole barrel pump according to the structure. Combined pump: consists of an outer working cylinder and a bushing, a plunger (with upper and lower moving Versail in the plunger) and a fixed Versail in the outer working cylinder. The whole barrel pump consists of a pump cylinder, a plunger (with the upper and lower sides of the plunger, and a fixed valve). Compared with the combined pumping pump, it has the following advantages: simple structure, light weight, no bushing, no bushing misalignment during transportation and downhole, the length of the pump barrel can be made longer, and can be made into a long stroke pump .

    2. Observe the rod pump. The rod pump is assembled on the ground and connected to the lower end of the sucker rod column. The whole pump is lowered into the working cylinder with the circlip spring pre-installed at the predetermined position of the oil pipe through the oil pipe. The utility model has the advantages that the pump does not need to take out the oil pipe, and the pump is convenient to be inspected; the structure is complicated and the manufacturing cost is high; the pump diameter allowed to enter under the same oil pipe diameter is smaller than that of the tube pump, so the displacement is small. Therefore, the rod pump is suitable for wells with a lower pump depth but lower yield.

    3. Observe the electric submersible pump. The deep well pump underground unit includes submersible motor, protector, separator and multistage centrifugal pump. The submersible motor is a two-pole, three-phase squirrel-cage asynchronous induction motor. The protector is a device that uses the difference between the well fluid and the motor oil density to prevent the well fluid from entering the motor and causing a short circuit to burn the motor. The oil separator separates the free gas to prevent and reduce the gas from entering the pump, allowing the multistage centrifugal pump to function properly. The multistage centrifugal pump incrementally increases the pressure and velocity of the well fluid to obtain a certain lift and lift it to the ground.
