Abstract
The utility model provides a self-sucking pump which can block sundries and is characterized in that the tail end of an inlet branch 2 is connected with an upper water channel 3, the water outlet port of the upper water channel is provided with a filtering net 13 which can block sundries in water; the corresponding position of the upper water channel is provided with an upper water valve 11, the lower part of the upper water valve 11 is provided with a flange 12; an outflow tube 9 is connected with a water storage tank 6 and a switch valve 8 in turn; the inside of the water storage tank 6 is connected with a pressure switch 7; the pressure switch 7 and a motor 10 are serially connected with a power supply. The pump is connected with a tube well flange, the pump cavity can start the motor repeatedly after being filled with water, so water can be pumped to be used; the filtering net can block the sundries in the water when the water enters the filtering net and prevent the sand grains in the water from braising an impeller. The water forms certain pressure in the water storage tank after the switch valve is closed, the pressure switch is cut off and the motor stops rotating; the water pressure in the water storage tank decreases after the switch valve is opened, the pressure switch is communicated with the motor and the motor runs to pump water, one-time water intake can realize a plurality of water pumping intermittently, so the self-sucking aim is achieved. The water pump is of simple structure, long service life, versatility and labor saving, and is widely applied to various tube wells.
Description
One, technical field
The utility model relates to a kind of water pump, especially the self-priming pump of rural area pipe well application.
Two, background technique
At present, the water pump of using during the pipe well water lift of rural area must need plural people to cooperate and could draw up water at every turn when using, and diversion again and again bothers especially, and leaky appears in the spray motor that practices riding the waves easily that splashes during diversion; In addition, draw up in the next water and be mixed with sand grains and other foreign material, influence the life-span of water pump vane.
Three, summary of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of retaining self-priming pump of mixing, and is applied to and has removed the trouble of diversion again and again on the pipe well from, can also remove the foreign material in the water.
The technological scheme that solves its technical problem employing is: be provided with the impeller by driven by motor in the water pump cover; The water intake of one termination housing of intake pipe, the other end and last water drum join, and there is the filter screen that can block foreign material in the water at the water outlet place of last water drum by screw, and the corresponding positions of last water drum is equipped with water supply valve, and the dish that connects with the pipe well sealed attachment is arranged at the bottom of this valve; The water outlet of housing is connected to outlet pipe, and order is connected to water storage cylinder and switch valve on the outlet pipe, be provided with in the water storage cylinder and can control the pressure switch that electric motor starting stops, its switch with connect power supply after motor is connected.When drawing water, the Pan Chu that connects of pump is connected firmly connecing on the dish of pipe well with bolt seal, will fill water in the pump chamber from intake pipe earlier, actuating motor repeatedly, the impeller of water pump just can draw up water and use; Water is by filter screen in the process of drawing water, and filter screen just keeps off the foreign material in the water in last water drum.After should using up water, close the switch valve on the outlet pipe, owing to remaining in operation of motor, the water that sucts is full of water storage cylinder and the hydraulic pressure in the tube is raise, and pressure switch disconnects and makes the motor stall when being elevated to a certain degree, and water supply valve is closed at this moment, is full of water in the pump chamber.When needing to draw water once more, open switch valve, pump chamber release, pressure switch closure, the motor application of drawing water.
The beneficial effects of the utility model are: owing to be connected to water storage cylinder and switch valve on the outlet pipe, the pressure switch in the switch valve control water storage cylinder stops electric motor starting, add diversion for the first time after, start once more without diversion and just can draw up water come the self-priming of realization pump; Because the water outlet place of last water drum is provided with filter screen, and the foreign material that this net just can block in the water make it can not pass through impeller, and water pump vane is reduced wear, increase the life-span again.So this kind water pump structure is simple, be convenient to starting, function is many, and is safe and reliable, saves the labour, is suitable for the application of drawing water of the various pipe wells in rural area.
Four, description of drawings
Fig. 1 is the sectional structure chart of the assorted self-priming pump of the utility model retaining.
Fig. 2 is the circuit connection diagram of the utility model pressure switch and motor.
Five, embodiment
In the accompanying drawings, be provided with the impeller 4 that is used for absorbing water by motor 10 driven rotary in the housing 5 of assorted its pump of self-priming pump of the utility model retaining, the water intake of housing 5 is connected to intake pipe 2, and the other end of pipe and last water drum 3 join.There is filter screen 13 at the water outlet place of last water drum by screw, and this filter screen can be from the impurity the water that filter screen flows through (mainly being sand grains) retaining in last water drum; The lower inner part of last water drum 3 is provided with water supply valve 11, and this valve is opened when drawing water automatically, closes automatically during the motor stall, prevents the aqueous reflux in the water pump chamber; The bottom of valve is provided with and connects dish 12, and the connecing coil to seal to connect firmly of this dish and pipe well is used for drawing water; The downside of last water drum 3 is provided with impurity removing hole near the position of filter screen 13, is screwed with plug 1 in this hole, when foreign material are stacked into to a certain degree, open plug and can dispose foreign material.The water outlet of housing 5 is connected to outlet pipe 9, order is connected to water storage cylinder 6 and switch valve 8 on the pipe, pressure switch 7 is housed in the water storage cylinder 6, this switch with connect power supply after motor is connected, mainly be that automatic disconnection makes motor 10 stalls when the pressure of switch 7 contacts is elevated to a certain degree; The effect of switch valve 8 is to make water-filling and off-load in the water storage cylinder, to realize the self-priming of pump.
Claims (2)
1, the assorted self-priming pump of a kind of retaining has the impeller of driven by motor in this pump case, shell machine water intake is connected to intake pipe, and water outlet is connected to outlet pipe; It is characterized in that: the other end of intake pipe (2) and last water drum (3) join, the water outlet place of last water drum (3) is fixed with the filter screen (13) of foreign material in the energy dash, the corresponding positions of tube (3) is equipped with water supply valve (11), the bottom of valve (11) have with the pipe well sealed attachment connect dish (12); Outlet pipe (9) is gone up order and is connected to water storage cylinder (6) and switch valve (8), have in the water storage cylinder to control the pressure switch (7) that motor (10) starts stall, pressure switch (7) with connect power supply after motor (10) is connected.
