Description
Technical field
The invention belongs to farmland water conservancy works technical fields, are related to a kind of automatic starting method of pump, relate in particular to
A kind of automatic starting method of mixed-flow pump and centrifugal pump.
Background technology
Since reform and opening-up, Chinese agricultural development makes remarkable achievements, with the arable land less than the world 10%, base
Originally solves the food problem of 22% population of the world, wherein farmland water conservancy works facility has played suitable effect.At following 5 years
To in 10 years, country will increase input of the public finance to water conservancy, go in a big way construction of water conservancy works.In recent years, various regions irrigation and water conservancy
Input significantly strengthen, farmland water conservancy works are large in number and widely distributed, irrigate, wherein horizontal small centrifugal pump large number of with drainage pumping stations
With mixed-flow pump using more, or but before this pump-type starts in the past artificial recharge could start, it is time-consuming and laborious；Using vacuumizing
The method of pump starts, and can only often be manually operated, difficult to realize to automatically control, sometimes due to water pump installs blow-by, causes nothing
Method is drawn water；If realize automatic start, it is necessary to increase by two solenoid valves in vacuum pump and mixed-flow pump, centrifugal pump water outlet respectively,
Add the cost of entire pumping plant.
The content of the invention
The present invention needs artificial recharge that could start before activation for existing centrifugal pump and mixed-flow pump, time-consuming and laborious；It adopts
Started with the method for vacuum pumping pump, can only be manually operated, it is difficult to realize to automatically control, since water pump installs blow-by, cause nothing
The defects of method is drawn water；And realize automatic start, then it must increase by two electromagnetism at vacuum pump and mixed-flow pump, centrifugal pump water outlet
The deficiencies of valve, this undoubtedly adds entire pumping plant cost, proposes the automatic starting method of a kind of mixed-flow pump and centrifugal pump, utilizes list
Phase spiral vortex self-suction pump is to mixed-flow pump, centrifugation pump priming, when water filling depth can flood mixed-flow pump, centrifugal pump impeller, using mixed
Stream pump, the liquid level detecting sensor of centrifugal pump corresponding position installation will detect signal transmission to automatic transfer switch, so as to stop
Single-phase spiral vortex self-suction pump starts mixed-flow pump, the main starting switch of centrifugal pump, reaches and installs simple, automatic start-stop, low-cost mesh
's.
The technical scheme is that：The automatic starting method of a kind of mixed-flow pump and centrifugal pump, which is characterized in that including such as
Lower operating procedure：
(1) on the basis of former mixed-flow pump and centrifugal pump, former vacuum pumping pump is changed into single-phase spiral vortex self-suction pump；
(2) in mixed-flow pump and centrifugal pump original annotation water hole or installation liquid level detecting sensor is vacuumized at hole, and detection signal is passed
It is defeated to arrive water-pump controlling box；
(3) press live start button or long-range starting switch starts pump station controller；
(4) single-phase spiral vortex self-suction pump is started to water filling in the pump housing of mixed-flow pump and centrifugal pump；
(5) when mixed-flow pump and centrifugation pump priming depth flood impeller, signal is passed into control cabinet using liquid level detecting sensor
Switching switch, stop single-phase spiral vortex self-suction pump；
(6) start mixed-flow pump and the switch of centrifugal pump draws water.
Beneficial effects of the present invention are：The automatic starting method of a kind of mixed-flow pump and centrifugal pump proposed by the present invention starts
Method And Principle is clear, by outside the configuration of conventional water pump motor, increasing an auxiliary pump (self priming pump) to main pump water inlet pipe and pump chamber
(mixed flow pump chamber, centrifugation pump chamber) water filling, and liquid level detecting sensor is configured in main pump, realize the automatic start-stop of water filling auxiliary pump, when
After auxiliary pump is filled to main pump pump chamber axis, auxiliary pump is automatically stopped, and opens main pump, this method is at low cost, effect is good, can extensive use
In on irrigation and water conservancy mixed-flow pump and centrifugal pump irrigation pumping station, especially there is good using effect to integral intelligent pumping plant.
Description of the drawings
Fig. 1 is mixed-flow pump and centrifugal pump automatic start flow diagram of the present invention.
Specific embodiment
The invention will be further described below：
As shown in Figure 1, the automatic starting method of a kind of mixed-flow pump and centrifugal pump, including following operating procedure：
(1) on the basis of former mixed-flow pump and centrifugal pump, former vacuum pumping pump is changed into single-phase spiral vortex self-suction pump；
(2) in mixed-flow pump and centrifugal pump original annotation water hole or installation liquid level detecting sensor is vacuumized at hole, and detection signal is passed
It is defeated to arrive water-pump controlling box；
(3) press live start button or long-range starting switch starts pump station controller；
(4) single-phase spiral vortex self-suction pump is started to water filling in the pump housing of mixed-flow pump and centrifugal pump；
(5) when mixed-flow pump and centrifugation pump priming depth flood impeller, signal is passed into control cabinet using liquid level detecting sensor
Switching switch, stop single-phase spiral vortex self-suction pump；
(6) start mixed-flow pump and the switch of centrifugal pump draws water.
Present invention startup Method And Principle is clear, and the present invention increases by an auxiliary pump (self-priming outside the configuration of conventional water pump motor
Pump) to main pump water inlet pipe and pump chamber (mixed flow pump chamber, centrifugation pump chamber) water filling, and liquid level detecting sensor is configured in main pump, it realizes
The automatic start-stop of water filling auxiliary pump, after auxiliary pump is filled to main pump pump chamber axis, auxiliary pump is automatically stopped, open main pump, this method into
This is low, effect is good, can be widely applied on irrigation and water conservancy mixed-flow pump and centrifugal pump irrigation pumping station, especially to integral intelligent pumping plant
With good using effect.
