Abstract

The utility model relates to a self-control self-suction pump without sealing, which comprises a motor, a coupling, a sealing box an exhaust valve, a pump body, and so on. After the motor and an electricity-controlled valve start, a motor shaft drives a pump shaft by the coupling to rotate smoothly. Under the effects of an annular ball bearing and a cylinder bearing, medium is sucked into the pump body by a U-shaped liquid suction opening via an impeller, and under a certain pressure, the medium can be output from a liquid outlet. The utility model adopts an interlinking multi-surface centrifugal sealing device and overcomes the problems of moving, bubbling, dripping and leaking, which exist in other pumps. The utility model adopts an electrical air control valve to realize the functions of once- drainage, life-long self-absorption, and the service life is more than ten times longer than similar products, and all types of pumps produced can be moved to any post to work.

Description

There is not sealing automatic control self-priming pump

Technical field:

The utility model relates to pump, and particularly relating to does not have sealing automatic control self-priming pump.

1. motor, 2. coupling, 3. bearing gland I, 4. carriage, 5. bearing gland II, 6. bearing gland III, 7. bearing support, 8. support, 9. electrically-controlled valve, 10.U the type liquid sucting port, 11. sealed cases, 12. tapholes, 13. radial ball bearings, 14. oil sealing I, 15. cylindrical bearings, 16. oil sealing II, 17. bearing gland IV, 18. round nut II, 19. safety check, 20. pairs of impellers, 21. outlet valves, 22. the pump housing, 23. pump shafts, 24. hanging bolts, 25. round nut I.

Embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing;

In the drawings, the utility model does not have sealing automatic control self-priming pump and is made up of institutes such as motor 1, coupling 2, sealed case 11, outlet valve 21, the pump housings 22, it is characterized in that: the bottom of motor 1 is arranged on the carriage 4 by Bolt Connection, carriage 4 centers, one end of motor shaft is provided with coupling 2, and the other end of coupling 2 is provided with pump shaft 23; The below of carriage 4 is provided with bearing support 7, upper end, the center pump shaft 23 of bearing support 7 is provided with bearing housing, be provided with two radial ball bearings 13 in the bearing housing, be provided with bearing gland I 3 and fastening above the bearing housing by round nut I 25, be provided with bearing gland II 5 and oil sealing I 14 sealings below, the lower end pump shaft of bearing support 7 is provided with bearing housing, be provided with cylindrical bearing 15 in the bearing housing, be provided with bearing gland III 6 above the bearing housing, be provided with bearing gland IV 17 and oil sealing II 16 sealings below; Bearing support 7 belows are provided with support 8; Support 8 belows are provided with the pump housing 22, the upper end pump shaft 23 at the pump housing 22 centers is provided with sealed case 11, pump shaft 23 is provided with and pays impeller 20 and by round nut II 18 lockings in the sealed case 11, the following top of pump shaft 23 is provided with main impeller and is locked by hanging bolt 24, the bottom, center of the pump housing 22 is provided with U type liquid sucting port 10, the top of 10 mouthfuls of ends of U type liquid sucting port is provided with electrically-controlled valve 9, circuit on the electrically-controlled valve 9 communicates with motor 1 circuit, left bottom at U type liquid sucting port 10 is provided with taphole 12, the upper right of the pump housing 22 is provided with liquid outlet, the upper end of liquid outlet is provided with safety check 19, and bottom righthand side is provided with outlet valve 21.During concrete enforcement, actuating motor and electrically-controlled valve, motor shaft drives pump shaft under the effect of radial ball bearing and cylindrical bearing by coupling, rotation stably, medium sucks the pump housing by U type liquid sucting port through impeller, reaches certain pressure, and medium is exported by liquid outlet.After turning off power supply, because the interaction medium of safety check seldom falls after rise, open outlet valve and reduce pressure in the pump housing, the taphole of the left bottom by U type liquid sucting port bleeds off remaining media again.Next time is when starting, same operation, the utility model has overcome the phenomenon of " run, drip, leak " medium of other pump existence, function with " drainage ", " self-priming throughout one's life ", working life is long more than 10 times than like product, and various types of water pumps of production can be passed operation on any post.
