Abstract

The utility model presents an automatic submersible pump which is a water pump provided with an electric motor fixedly connected to the base plate. The top of the water outlet of the pump is provided with a gasket and the base plate is fixed with an outer housing. The water pump connected with the electric motor is covered in the outer housing. When the water pump works under the control of the electric motor, a definite water supply pressure can be formed in the system of the outer housing and the water outlet pipe. The water pressure switch for control supply arranged in the end cover of the electric motor can control the electric motor on and off automatically according to the variation of the water pressure in the outer shell, in order to provide clean deep well water for the users. The utility model is characterized most in that the users need not to build a high-level tank and can efficiently avoid a secondary pollution to the water quality, and the users can have an apparent effect of saving electricity and water during using the pump, and also have a convenient management and maintenance.

Description

Automatic submersible pump

Technical field:

The utility model relates to water pump, and specifically automatic submersible pump belongs to the deep well water pump technical field of control automatically, is particularly suitable for town-dweller-rural-family and is used for automatic control to deep-well pumping.

Background technique:

Along with the high speed development of Chinese national economy and improving constantly of broad masses of the people's living standard, people are more and more high to the quality requirement of domestic water.At present, the life of urban resident water is to be concentrated by the waterworks to adopt water, supply with after the unified disinfection, but, at tap water not universal cities and towns and the extensive country regions, it is still quite difficult to solve resident living water, generally be to adopt to build deep-well, solve with artificial pumping's mode, can adopt water pump to draw water on the ground that electric power resource is arranged, mostly be to build high-order water reservoir on the roof, with water pump well water is evacuated to and saves as family in the head-tank domestic water is provided, but, when drawing water, operating head-tank by experience, be difficult to accurately grasp the water level of head-tank water storage, the phenomenon that leaks in the casual pond of head-tank takes place when drawing water easily, manipulate extremely inconvenient, particularly in that being pumped and store isoperimetric to head-tank, phreatic water turns over the secondary pollution that is easy to cause water quality in the journey, when especially the head-tank inner storing water time is long slightly, the pollution level of water quality is even more serious, the user has to its discharging is lost, cause the significant wastage of water resources and electric energy, if use reluctantly, its sanitary condition is troubling really again, and expense is also higher when building head-tank, and the clean and maintenance management to head-tank in use also comparatively bothers.

The model utility content:

The utility model is the deficiency that exists at existing head-tank water storage water supply installation, propose a kind of simple in structure, make and install easily, automatic submersible pump easy for operation, it is achieved by the following technical solution: it is the water pump that fixed installation is connected with motor on base plate, it is characterized in that in the end cap of motor, being fitted with hydraulic pressure control power switch, water outlet roof anchorage at water pump is equipped with support, the slide bar that is connected in top board and press table is worn and is led in support, between top board and press table, be fitted with sealing gasket, the one group of directed guide rod that is connected in press table places in the water outlet, the sealing gasket that is fitted between top board and the press table can be gone up, following mobile opening and closing of fault water outlet, on base plate, be installed with frame, and the water pump sealing cover that will be connected with motor is in frame, on frame, be equipped with sealing duct and outlet pipe, power lead inserts hydraulic pressure control power switch control machine operation by sealing duct, during the driven by motor wheel rotation, the phreatic water that sucks backs down the sealing gasket of water outlet to the frame inner water-supply, when hydraulic pressure increases to predetermined value in the frame, hydraulic pressure control power switch disconnects under hydraulic action, motor quits work, sealing gasket seals water outlet under hydraulic action, promptly form certain pressure of supply water in frame and in the discharge piping, when water, hydraulic pressure in the frame descends, the closed again energising of hydraulic pressure control power switch, motor is resumed work, can supply with phreatic water to the user, when stopping water, hydraulic pressure increases to predetermined value again gradually in the frame, hydraulic pressure control power switch is disconnected, and motor quits work again.Great advantage of the present utility model is need not build head-tank, can avoid the secondary pollution of well water, and the phreatic water of sanitation and hygiene can directly be provided for the user at any time, and in use, the power saving water-saving result is good, and management maintenance is convenient.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model.

Embodiment:

The automatic submersible pump that the utility model proposes is work like this: it is that the water pump 4 that is connected with motor 6 is installed on base plate 2, in the end cap 13 of motor 6, be fitted with and start electric capacity 14, sealing duct 9 and the hydraulic pressure control power switch 12 that is lined with sealing gasket 8, water outlet 23 tops at water pump 4 are equipped with support 17 by standing screw 21, the slide bar 18 that is connected in top board 19 and press table 20 is worn and is led in support 17, between top board 19 and press table 20, be fitted with sealing gasket 22, three directed guide rods 24 that are connected in press table 20 place in the water outlet 23 has directing effect, be lined with the frame 16 of seal ring 3 and will be connected with water pump 4 sealing covers of motor 6 in frame 16 in fixed installation on the base plate 2, on frame 16, be equipped with sealing duct 10, outlet pipe 15 and handle 26, during use, put it in the deep well, power lead 11 is by sealing duct 10, sealing duct 9 inserts 12 control motors, 6 energisings of hydraulic pressure control power switch or outage, is supplied water to the user by outlet pipe 15.During work, motor 6 impeller 5 are rotated, phreatic water is through filter screen 1, water intake 25 sucks in the water pump 4, and the sealing gasket 22 that backs down water outlet 23 is to frame 16 inner water-supplies, when the hydraulic pressure in the frame 16 of sealing increases to predetermined value gradually, pressure sensitive contact 7 actions of hydraulic pressure control power switch 12, make hydraulic pressure control power switch 12 disconnect outage, motor 6 quits work, sealing gasket 22 seals the water outlet 23 of water pump 4 under hydraulic action, promptly form certain pressure of supply water in frame 16 and in outlet pipe 15 pipings, when user's water, the hydraulic pressure in the frame 16 slowly descends, and pressure sensitive contact 7 counteragents make the closed once more energising of hydraulic pressure control power switch 12, motor 6 is resumed work again, can be continuously to the phreatic water of user's supplying clean health, when stopping water, when the hydraulic pressure in the frame 16 increase to predetermined value again gradually, make hydraulic pressure control power switch 12 disconnect outage once more, motor 6 quits work immediately.So circulation can provide the phreatic water of sanitation and hygiene repeatedly automatically at any time for the user.
