Abstract
The utility model provides a self priming pump system with trade water installation, includes an oral siphon, a pump body and an outlet pipe, a pump body connection pump body motor, the oral siphon is being equipped with one from the suction tube near pump body part, meet a water pipe from suction tube bottom, by a solenoid valve and water pipe connection, the solenoid valve still with the connection of pump body motor.
Description
Technical field
The utility model relates to a kind of centrifugal pump, particularly relates to a kind of self-priming pump system with changing water device.
Background technique
Can solve centrifugal pump startup self-priming problem by arranging from suction tube, but self-priming centrifugal pump only needs to open several hours usually, the pump housing and impeller are but all immersed in always to be had in the sewage of corrosive action, thus causes the working life of pump.This just needs to ensure that centrifugal pump can self-priming when starting, and reduces sewage again to the corrosion of centrifugal pump, thus ensures the working life of centrifugal pump.
Model utility content
The purpose of this utility model is to provide a kind of self-priming pump system with changing water device.
The technical solution of the utility model: a kind of self-priming pump system with changing water device, comprises a water inlet pipe, a pump housing and an outlet pipe; The described pump housing connects a pump housing motor; Described water inlet pipe is being provided with one from suction tube near pump body portion; Described connects a running water pipe bottom suction tube, is connected with running water pipe by a solenoid valve, described solenoid valve also with the connection of described pump housing motor.
Sewage treatment self-priming pump system described in the utility model can realize automatically and manually changing water mode.
The beneficial effects of the utility model are, decrease the corrosion of sewage to centrifugal pump, thus ensure the working life of centrifugal pump.
Accompanying drawing explanation
Fig. 1 is solenoid valve and pump housing Principle of Electric Engine schematic diagram;
Fig. 2 is the utility model structural representation.
In figure: 1, from suction tube; 1-1, from suction tube water inlet; 2, running water pipe; 3, outlet pipe; 4, solenoid valve; 5, filter screen; 6, the pump housing; 6-1, pump housing motor; 7, water inlet pipe.
Embodiment
Below in conjunction with embodiment, concrete detailed description is done to the utility model:
As shown in the figure, a kind of self-priming pump system with changing water device, comprises water inlet pipe 7, pump housing 6 and an outlet pipe 3.
Improvement of the present utility model is mainly, the described pump housing 6 connects a pump housing motor 6-1; Described water inlet pipe 7 is being provided with one from suction tube 1 near the pump housing 6 part; Described connects a running water pipe 2 bottom suction tube 1; be connected with running water pipe 2 by a solenoid valve 4; described solenoid valve 4 also with the connection of described pump housing motor 6-1; by the chain control of solenoid valve 4 and centrifugal pump; realize solenoid valve 4 unlatching when centrifugal pump is shut down and change water; in automatic closedown at the end of changing water, wait for that centrifugal pump starts next time.Technological scheme before contrast arranges one-way bottom valve and filter screen 5, while the technical program realizes the startup of centrifugal pump self-priming, reduces sewage again to the corrosion of centrifugal pump, thus ensures the working life of centrifugal pump.
The working principle such as Fig. 2, the RJ that change water device are thermorelay, and ZC is the control contactor of pump motor, and QA is start button, TA is stop button, and YJ is time delay relay, and DCF is solenoid valve 4 coil controlling tap water, K is automatic/hand switch, and J1, J2 are control relay.
Under manual mode, press stop button TA, during centrifugal pump stall, time delay relay YJ instantaneously electric, its normally opened contact yj closes instantaneously, so solenoid valve DCF coil obtains electric, tap water enters from suction tube 1 by the solenoid valve DCF coil opened, the sewage more in creeling.When after time delay relay delay time (time is determined according to from suction tube 1 volume and running water pipe 2 size), contact yj disconnects, so solenoid valve DCF coil blackout, solenoid valve 4 cuts out, and changes water and terminates;
Under self-starting mode, control the start-stop of motor by control relay J1, J2 and solenoid valve 4 changes water.Wherein J2 is only energized very short time when J1 disconnects.Now, described solenoid valve 4 can select DC electromagnetic valve 4, then need only be equipped with corresponding voltage transforming rectifier for it, and control with the normally opened contact of time delay relay.
In addition, described water inlet pipe 7 can be made up of some straight tubes and bend pipe, can need increase and decrease pipeline number, connect between pipeline by modes such as flanges according to aspects such as places; Described water inlet pipe 7 water inlet is provided with filter screen 5, enters centrifugal pump for preventing the foreign material in cesspool; The water inlet section of described water inlet pipe 7 stretches in cesspool;
The technical program it should be noted that when implementing and often be in water-filled state in order to make from suction tube 1, and the water outlet height of outlet pipe 3 must be not less than from suction tube water inlet 1-1 height; Meanwhile, according to standard atmospheric pressure, need to make the height of more than water inlet pipe 7 water level be no more than 10m; In addition, if very large from the volume of suction tube 1, be conducive to solving startup self-priming, but waste material; Too small from suction tube 1 volume, then negative pressure in cylinder can be made to be not enough to sewage is pressed into from suction tube 1 by barometric pressure, to make self-priming failure, preferably, from suction tube 1 minimum volume Vmin=(5 ~ 6) V here
0, wherein V
0for starting the volume of front water inlet pipe 7 road inner cavity.
It should be pointed out that above-described embodiment only as the specific descriptions to innovation and creation, but not the restriction to its protection domain.
