Abstract

The utility model relates to a multi-purpose centrifugal pump, in which the water blade wheel (6) and the wind blade wheel (7) with axle sleeves are put into the pump case (5) in a concentric way. The axle sleeve of the water blade wheel is fixing connected with the motor shaft, and the outside of the axle sleeve of the wind blade wheel is provided with a mechanical spring (15) and a double-direction thrust bearing (14). The end surface of the axle sleeve is closely connected with big cap nuts (13) connected with the screws, and the external edges of the two wheel side panels near the two blade wheels are provided with a plurality of clutch grooves (17) or clutch convex teeth (18) at corresponding positions; the utility model also has a movable sleeve (8) for the accessory, a dust pick-up hose and a dirt catcher. The pump is able to supply water with pump, blast air, draft air, absorb dust and to be used as a submersible pump, realizing a machine with multi functions.

Description

Multi-purpose centrifugal pump

The utility model belongs to the centrifugal pump field.

In existing centrifugal pump technology particularly in the centrifugal submersible pumps technology, great majority are according to application target and fed sheet of a media and the single-use pump that specialized designs is made, for example, transporting water or other liquid are used centrifugal pump always, carry air or other gaseous medium then to adopt structure to be different from the blower fan of general liquid delivery pump, the medium that dust exhaust apparatus is carried also has special dust collection equipment based on gas.Also find no the report of the device that can be used for the multiple different physical aspect media of pumping or the product that appears on the market, more do not find can be used for the report that gas-liquid is carried, be can be used as submersible pump again.

The purpose of this utility model provides a kind of centrifugal pump that integrates pumping liquid, gas and dust-absorbing function and can also be used as submersible pump, replaces multiple devices with an equipment and finish multiple work.

The utility model is realized its purpose as follows: the water impeller 6 and the fan blade 7 that have axle sleeve respectively are contained in the pump case 5 together with one heart, the axle sleeve of water impeller 6 is fixedlyed connected with motor shaft, the axle sleeve of fan blade 7 is equipped with spring 15 and doubledirection thrust bearing 14 outward, the axle sleeve end face is right after the big nut 13 that is threaded with end cap 10, in the outer of water impeller two the wheel side plates adjacent with fan blade corresponding clutch slot 17 in several positions or clutch double wedge 18 is arranged respectively; This centrifugal pump also has annex quill 8, hose and Lu dirt device.Floating block frame 25 is arranged in the rear cavity of motor 1, floating block guide rail 23 and the lower contact on the guide rail extension bar 22 are arranged on the floating block frame, floating block 21 is slidingly connected with guide rail 23, on the cross-arm that is stretched out by the floating block upper-end surface upper contact 24 is arranged; Motor bottom has unidirectional delivery valve 20.

Of the present utility modelly many can be used as liquid pump pumps water or other liquid, also can be used as blower or induced draft fan air blast or exhausting,, also very be suitable for doing submersible pump and use, realized a tractor serves several purposes as the vacuum cleaner dust suction with centrifugal pump.Motor has been done as after the repacking described in the utility model, if there is low amounts of water to enter in the motor, motor can drain the water away automatically during as submersible pump; If big water gaging enters motor, then motor can be cut off the electricity supply automatically, prevents burn-down of electric motor.

Embodiment further specifies the utility model below in conjunction with accompanying drawing:

Fig. 1 is these many structural representations with centrifugal pump.

Fig. 2 is the mounting point schematic representation of interior floating block of motor rear cavity and floating block frame.

Water impeller 6 and fan blade 7 are contained in the pump case 5 with one heart, the axle sleeve of water impeller 6 is fixedlyed connected with key with screw 4 with motor shaft, the sleeve outer surface of fan blade 7 joins with end cap of pump 10 and doubledirection thrust bearing 14, all there is jump ring to snap in axle sleeve before and after the central ring of doubledirection thrust bearing 14, between end cap 10 and doubledirection thrust bearing 14, spring 15 arranged with the location; The big nut 13 that presses doubledirection thrust bearing 14 is threaded with end cap 10; The positioning screwn 11 that has handle 12 is contained in the nut of fixedlying connected with big nut 13.There is the terminal box 2 and the power line 3 of waterproof sealing motor 1 top, unidirectional delivery valve 20 is arranged at the bottom, the floating block frame 25 that in the motor rear cavity that specially extends, has a profile diameter and motor case internal diameter to be complementary, guide rail 23 and the lower contact on the guide rail extension bar 22 are arranged on the floating block frame, floating block 21 can slide up and down along guide rail 23, the cross-arm that stretches out from the floating block upper-end surface has upper contact 24, and the motor power-supply wire disconnecting is on upper and lower contact.Whole pump connects motor and is installed on the frame 19.When needs pumps water or other liquid, twisting handle 12 unclamps positioning screwn 11, big nut 13 is unscrewed all backs positioning screwn 11 reset original position, this moment, spring 15 pushed away doubledirection thrust bearing 14 outer moving, make fan blade 7 leaving water impellers 6, clutch double wedge 18 has also left clutch slot 17, and fan blade can not rotated along with the rotation of water impeller; Insert moving casing 8 again from suction port 9, its effect is an issuable turbulent flow when reducing pump water; Medium promptly enters the pump housing again from delivery outlet 16 outflows from suction port 9 after starting centrifugal pump.In the time of this pump will being used for pump gas such as air blast or axle wind, unclamp positioning screwn 11 earlier, be screwed onto big nut 13 the tightest, and by screw 11 location, this moment, big nut pressed doubledirection thrust bearing 14 and the axial displacement by fan blade 7 makes fan blade 7 rely on water impeller 6, clutch double wedge 18 on fan blade embeds in the clutch slot 17 of water impeller 6, and two impellers closely link to each other; Take out quill 8, can supply gas by turn on pump, the water impeller 6 of this moment and fan blade 7 rotate together supplies gas.In the time of this pump will being used for dust suction, identical when each component position of pump body concerns with pump gas, also take off moving casing 8, on inlet opening 9 and delivery outlet 16, connect hose and Lu dirt device (not drawing among the figure) respectively, can carry out the dust suction operation.

When centrifugal pump of the present utility model was used as submersible pump, as entering low amounts of water in motor 1 body, the pressure in the motor case can be discharged these hydraulic pressure toward unidirectional delivery valve 20; And when motor bleeds big water gaging; water in the casing makes floating block 21 along guide rail 23 come-ups; upper contact 24 on the cross-arm that is fixed on floating block is disengaged with the lower contact 22 that is fixed on the guide rail extension bar; supply disconnecton; motor just can not rerun as the oven dry of not anhydrating; avoid the generation of burn-down of electric motor, played automatic protective action.
