Abstract
The utility model discloses a self suction centrifugal pump capable of automatic water changing, which is mainly composed of a centrifugal pump body, a self suction cylinder, and an electromagnetic valve. The utility model is mainly used for industrial and civil drainage. The utility model is used for discharging industrial sewage especially. The utility model has the advantages of convenient start-up operation, less maintenance, and long service life.
Description
The utility model belongs to electromechanical equipment water pump class technical field, be specifically related to a kind of have start self-priming and stall from the centrifugal pump of moving water function.
Existing centrifugal pump body can not directly start owing to there is the air sinuses phenomenon, must be earlier with fills with water in the pump housing before starting.For the water that starts preceding injection is not run off, unidirectional bottom valve must be established in centrifugal pump water inlet pipe road junction.The one, each start-up operation is pretty troublesome, and the 2nd, bottom valve leaks easily even damages, and cause to start, and the maintenance of bottom valve is taken a lot of work bothersome again very much.After adopting this novel practical technology, do not need water filling before the startup, can directly start.When the centrifugal pump stall, realize the replacing of sewage in the pump housing automatically, avoided the long-time corrosion of sewage the pump housing and impeller.
The utility model purpose is to provide a kind of directly self-priming to start, and stall is from the centrifugal pump of moving water.Both made things convenient for start-up operation, avoided again, do not increased corrosivity sewage again to the pump housing and impeller excessive corrosion simultaneously the loaded down with trivial details maintenance of water inlet pipe bottom valve.
The utility model is from moving the water self-priming centrifugal pump mainly by centrifugal pump body, water inlet pipe, filter screen, constitute from suction tube, connecting tube, solenoid valve.Between the inlet of centrifugal pump body 2 and water inlet pipe 10, set up one, and be connected with water inlet pipe 10 with loose joint 5 from suction tube 4.Be provided with tap water connecting tube 7 from suction tube 4 bottoms, between tap water connecting tube 7 and running water pipe 9, set up a solenoid valve 8, the drive motor 1 electrical interlocks control of the control coil DCF of solenoid valve 8 and centrifugal pump body 2.Can adopt general steel plate or engineering plastics to make from suction tube 4, solenoid valve 8 can be selected stainless steel or engineering plastics material for use.
Be further described below in conjunction with accompanying drawing:
Fig. 1: the structural drawing of moving the water self-priming centrifugal pump for the utility model certainly;
Fig. 2: be the electrical interlocks control graph of the utility model centrifugal pump drive motor and solenoid valve.
The outlet pipe 3 of centrifugal pump body 2 is identical with the height of water inlet pipe 10.Water inlet at water inlet pipe 10 is equipped with filter screen 6, enters damage impeller in the centrifugal pump body 2 to prevent the foreign material in the water pond.Full water is always store in each startup later in suction tube 4, as long as be not less than 5 ~ 6 times of water inlet pipe 10 inner cavity volumes from the volume of suction tube 4, the height of water inlet pipe 10 is not higher than 10 meters, and total energy realizes successfully that by the water storage in suction tube 4 self-priming of centrifugal pump body 2 starts next time.When centrifugal pump body 2 stalls, control by the drive motor 1 of centrifugal pump body 2 and the electrical interlocks of solenoid valve 8 coil DCF, automatically open solenoid valve 8, tap water enters by solenoid valve 8 from running water pipe 9, to change from the sewage in suction tube 4 and the centrifugal pump body 2, prevent the excessive corrosion of mordant sewage centrifugal pump body 2.When changing the water end, solenoid valve 8 cuts out automatically, finishes this working procedure, waits for starting working procedure next time.
RJ is a thermorelay, and ZC is the control contactor of the drive motor 1 of centrifugal pump body 2, and QA is a start button, and TA is for stopping button, and YJ is a time delay relay, and DCF is the control coil of solenoid valve 8.When TA presses, during 1 stall of centrifugal pump drive motor, time delay relay coil YJ moment gets, its outage time-delay normally opened contact YJ-1 moment closure, so the control coil DCF of solenoid valve 8 gets, tap water is entered from suction tube 4 by the solenoid valve of opening 8 by water supply pipe 9, more the sewage in the creeling.The setting time t of process time delay relay YJ is after second, and the outage of time delay relay time-delay normally opened contact YJ-1 disconnects, so the control coil DCF dead electricity of solenoid valve 8, solenoid valve 8 cuts out, and changes the water process and finishes, and waits for entering start-up course next time.The setting time t of time delay relay YJ looks from the caliber of the volume of suction tube 4 and running water pipe 9 and determines.If the solenoid valve of selecting for use is a DC electromagnetic valve, then need only be for it is equipped with corresponding transformation rectifying device, and control with the outage time-delay normally opened contact YJ-1 of time delay relay and to get final product.
Owing to set up, realized the self-priming startup of centrifugal pump, the loaded down with trivial details process of water filling in the necessary earlier past pump before having avoided starting from suction tube.Cancel the bottom valve under water of water inlet, also avoided complicated bottom valve maintenance; Owing to designed and moved the water device certainly, prevented the long-time excessive corrosion of sewage again to centrifugal pump, prolonged the working life of centrifugal pump.
The utility model confirms through on probation, and is respond well.Simplify the start-up operation step greatly, reduced the maintenance load of centrifugal pump.Especially in fabricated metals and chemical industry, centrifugal pump only need leave several hrs every day, and sewage has the draining occasion of corrosion again to the pump housing, owing to increased and moved the water device certainly, realizing starting under the situation of self-priming, do not increase the etching time of sewage during the centrifugal pump stall again, keep the cleaning in the pump housing centrifugal pump.
