Embodiment 1

[0017] Such as figure 1 As shown, the front pump 1, the main pump (also known as the water injection pump) 3, and the follower front pump 2 operate in series, all of which are centrifugal pumps, and the water outlet of the main pump 3 supplies water to the water distribution pipeline 9. The front pump 1, the main pump 3 and the servo front pump 2 are all driven by the main pump motor 4, wherein the front pump 1 is driven by the main pump motor 4 through the magnetic coupling 6, and the servo front pump 2 is driven by the main pump motor 4 is driven by a magnetic coupling 5. During the operation of the main pump, according to the pressure requirements of the water distribution pipeline, the speed of the front pump is adjusted through the magnetic coupling 6. The set pump is disconnected from the running main pump or restored to the series operation relationship. The main pump 2 is a multi-stage pump (generally no less than 10 stages), the pre-stage pump 1 and the follow-up pr...

Embodiment 2

[0023] Such as figure 2 As shown, when the pressure required by the water distribution pipeline 9 has been changing within a small range, no follow-up front pump is provided, and only the front pump 1 and the main pump 3 are used to form a series operation process, that is, the front The pump 1 sucks the water from the water supply tank 8, feeds water to the inlet of the main pump 3, and finally outputs it to the water distribution pipeline 9 from the outlet of the main pump 3. The main pump 3 runs at the rated speed, and the speed of the front pump 1 is adjusted by the magnetic coupling 6 to realize the adjustment of the output pressure of the main pump 3 so as to match the pressure required by the water distribution pipeline 9 .

[0024] According to the pressure requirements of the water distribution pipeline, the front pump can be started and stopped at any time during the operation of the main pump. When the clutch function of the magnetic coupler 6 is used to start the...

Abstract

The invention relates to a method for eliminating the pressure difference of pump pipes in a water injection system by using a magnetic coupler. The pre-pump, the follow-up pre-pump and the main pump are centrifugal pumps and run in series, and the water outlet of the main pump supplies water to the water distribution pipeline. It is characterized in that the speed of the front pump is adjusted by the magnetic coupling; during the operation of the main pump, according to the pressure requirements of the water distribution pipeline, the front pump and the follow-up front pump can be separated from the main pump or resume the series operation relationship .

Description

technical field [0001] The invention relates to a method for eliminating the pressure difference of a pump pipe of a water injection system by using a magnetic coupler. Background technique [0002] The technologies most relevant to the present invention are the patents "A Method for Eliminating Pressure Differences in Pump Pipes of Water Injection System" (Patent No. 00110026.2) and "A Highly Adaptable Method for Eliminating Pressure Differences in Pump Pipes" (Patent No. 200910072367.3). These two patents mainly connect the pre-pump and the main pump in series to adjust the speed of the pre-pump with low-pressure frequency conversion, so that the output pressure of the main pump matches the pressure required by the water distribution pipeline, eliminates the pressure difference between the pump pipes, and has a significant energy-saving effect. However, the maintenance of the frequency conversion speed regulation system is large, and because the maintenance work requires a...
