Abstract
Self-priming automatic water pump, relate to a kind of can be with the switching of water valve and Auto Power On supplies water or shut down the self priming vortex pump of sealing.This water pump, on outlet conduit or water outlet one side pump cover, pressure controller of installing in parallel in order to the manipulation pressure switch, the water storage tank that replaces existing automatic pump heaviness, in addition, aperture and the osculum that communicates with air-water separation chamber arranged on the cut water plane of the pump housing, make water pump have good self-priming performance, therefore use this water pump can take the water source easily nearby, and exempt to build water tower.Advantages such as it has uses reliably, and body is small and light, is convenient to packed and transported, and cost is lower.
Description
The present invention relates to a kind of can be with the switching of water valve and Auto Power On supplies water or shut down the self priming vortex pump of sealing.
Existing self-priming automatic water pump mainly is made up of motor, water pump, water storage tank, pressure switch etc., and the appearance of this water pump is for people's life with produce and utilize the water source that convenience is provided nearby.But this water pump body weighs greatly, and cost is higher, and when shutting down, each joint of pipeline does not allow any leakage, so easy break-down, and often influence is used.
The purpose of this invention is to provide a kind of improved self-priming automatic water pump, it can improve the reliability of work effectively.
The object of the present invention is achieved like this: on the pump cover of on the outlet conduit or water outlet one side, pressure controller of installing in parallel in order to the manipulation power switch, valve spring keeps certain elastic force in the pressure controller as long as adjust, just can control power switch exactly, thereby avoid causing the motor Fraquent start so that the accident of burning motor because of the pipeline small leakage.Meanwhile, in order to improve the self-priming performance of water pump, aperture and the osculum that communicates with air-water separation chamber arranged on the cut water plane in the pump housing.The osculum position should guarantee that cut water one side margin is not less than a blade pitch of impeller in corresponding radial position with the distance of side margin to osculum.This aperture circumferentially is being positioned at beyond the side runner, its effect is to finish in the self-priming process at water pump, makes the indoor a small amount of diversion of the pump housing and air-water separation, forms good outer circulation by aperture and osculum, to discharge in the air from pump body, thereby guarantee that the present invention has self-priming and automatic function.
The present invention only need just replace the water storage tank of existing automatic pump heaviness with a pressure controller, as long as adjust the elastic force of valve spring in the pressure controller, just play the effect that changes water storage tank size (being the precompression size), therefore structure is light and handy, cost is low with material province, and be convenient to packed and transported, good self-priming performance is arranged, so use reliable.In fact, also have only the self-priming automatic water pump of reliable performance, just can make the user take the water source easily nearby, and can exempt to make water tower as the use tap water.
Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is an assembling schematic representation of the present invention.
Fig. 2 is an A-A sectional view of the present invention.
Fig. 3 is the sectional view of pressure controller.
As Fig. 1, shown in 2, after the pump housing is filled it up with in diversion (adding about one glass of water when using first gets final product), starting motor (10), impeller (1) is rotated counterclockwise, under centrifugal action, diversion forms water ring on every side at impeller (1), and constantly increase on one side to osculum (16), then enter air-water separation chamber (4) by impeller passage through osculum (16), because the water ring inboard constantly is subjected to the impact of impeller blade, air in the intake pipe is mixed with water generation air water, after entering air-water separation chamber, flow velocity reduces, the floating ease of air, and the liquid aperture (12) that then pressure from cut water (2) plane is lower sucks (aperture (12) is positioned at side runner (15) in addition), the dispatch air is all discharged until the water inlet inner air tube so repeatedly, and the intake pipe and the pump housing just have been full of water, promptly finish self-priming work, water supply start this moment.The indoor air that constantly gathers of air-water separation when reaching certain pressure, promptly backs down and is loaded on water outlet safety check (6) on one side between air-water separation chamber (4) and the pump cover (5), discharges from water outlet (14).(13) be water intake.
As shown in Figure 2, (11) suck the pump housing (3) from the water inlet when liquid, form highly pressurised liquid through rotary blade, and flow out water outlet one rear flank from safety check (6) and be divided into two-way: the one road flows to water outlet (14); Flow to the pressure chamber (22) on pressure controller (8) the right shown in another Lu Zeru Fig. 1,3 through connecting tube (7), flow in the storage pressure chamber (24) through wall road (18) and safety check (17) again.The then direct pilot pressure switch (9) in chamber is pressed in this storage.When shutting down, the hydraulic pressure P of chamber is pressed in storage
1Hydraulic pressure P with the pressure chamber
2Equate that valve (20) is failure to actuate, simultaneously, room pressure makes pressure switch (9) be in off state.(19) be retaining spring.(21) be pressure spring, its elastic force is F.So arbitrary water valve opening on outlet conduit is the hydraulic pressure P of pressure chamber
2Descend, then P
1＞P
2, work as P
2Drop to
P
2＜P
1-F
The time, valve (20) action, then, storage presses chamber hydraulic pressure to make pressure switch (9) closure that resets thereupon descending, so motor (10) starting, water pump is an automatic water-supply.
When stopping water, use water valve as long as close, this moment, water pump continued water filling in pressure controller (8), pressed under the ever-increasing hydraulic action in chamber in storage until power switch to disconnect, and water pump is promptly cut off the water automatically.
(23) be the installation screw of connecting tube (7).
For anti-impurity enters in the pump, can be at intake pipe end installing guard.
