Abstract

The utility model relates to a straightway self-suction vane-pump for ships, particularly a rotary positive displacement pump belonging to the field of the mechanical technology. The utility model is mainly composed of a DC motor and a vane pump, wherein, a pump rotor on the vane pump is arranged on a vane shaft and eccentrically arranged in a pump stator. A bottom plate of the pump is arranged on one end surface of the pump stator, and the pump rotor is provided with a groove in which the vanes are arranged. The utility model has the advantages of simple structure, compactness, small size, fine self-suction capacity, high lift, balanceable operation, convenient use and maintenance, definite irrigation capability and low making cost. Compared with former various pumps, the utility model has high performance.

Description

Direct current self-priming vane pump peculiar to vessel

A kind of direct current self-priming vane pump peculiar to vessel is a rotarydisplacement pump, belongs to field of mechanical technique.

Before the utility model was made, a kind of direct current submersible pump was come into market gradually, is widely used.The characteristics of this pump are portable belts, have been replaced manually by electronic.This submersible pump mainly adopts impeller, and outer casing and direct current generator are formed.Though simple in structure but function singleness can only singlely be drawn water, no suction capacity, using scope is narrow, and power consumption is big, and heat loss is big, and motor burns out easily, so working life is short.Along with the development of situation, this single structure submersible pump can not satisfy user's demand.

The purpose of this utility model is to overcome above-mentioned deficiency, thereby provide a kind of direct current permanent magnet motor that adopts directly to drive the vane pump made from composite, can have good suction capacity lift height, volume is little, running steadily has the direct current self-priming vane pump peculiar to vessel of certain rinse capability.

The utility model mainly is made up of direct current permanent magnet motor and vane pump two-part.Vane pump is by blade pump shaft 10 ', pump stator 13, pump base plate 15, blade 17, and pump rotor 18 is formed.Pump rotor 18 is installed in blade pump shaft 10 ' and goes up and be installed in prejudicially in the pump stator 13, pump base plate 15 is installed in the end face of pump stator 13, be shaped on the radially deep trouth of four five equilibriums on the pump rotor 18, four blades 17 are installed in the groove, can be free to slide in groove, water inlet and outlet joint 19,19 ' is installed on the pump stator 13.

Description of drawings,

Fig. 1 is the utility model structural front view,

Fig. 2 is the utility model A-A sectional view,

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described,

The utility model rotor shaft 10 is fixedly mounted in the front and

rear cover

11,3 by two bearings 12, and rotor shaft 10 lower ends are extended for sharf 10 ' direct current permanent magnet motor and vane pump two-part are coupled together, and direct drive vane pump.

Direct current permanent magnet motor mainly is made up of casing 6, magnetic shoe 7, front cover 11, rear end cover 3, armature winding 8.Magnetic shoe 7 is adhesive in the middle of the casing 6, and front and

rear cover

11,3 adopts thermosetting plastics to make, and adopts screw 9 fixing with casing 6.Armature winding 8 is installed on the rotor shaft 10.Lighting outlet 16 is fixed on the case 1 and with brush pressing plate 15 and is connected.Power supply makes electric winding 8 produce magnetic field and rotation by brush pressing plate 5 and carbon brush 4.Because rear end cover 3 is made for insulating material, carbon brush 4, brush pressing plate 5 are directly installed in the hole of rear end cover 3, and can be free to slide in the hole.Centrifugal fan 2 is installed in the top of rotor shaft 10, and outer garden of fan blade and rear casing 1 keep certain interval.Rear casing 1 is installed on the rear end cover 3, and rear casing 1 bi-side are stretched out two lugs and are half garden shape and cover live part, is the cooling that guarantees motor.The side of front cover 11 and plane, the side of the plane of rear end cover 3, rear casing 1 all have vent hole, when centrifugal fan rotates, air is circulated from bottom to top.

Vane pump is mainly by pump shaft 10 ', and pump stator 13, pump rotor 18, blade 17, pump base plate 15 and water inlet and outlet joint 19 are formed.Pump rotor 18 is installed on the blade pump shaft 10 ', and be installed in prejudicially in the pump stator 13, be shaped on the radially deep trouth of five equilibrium on the pump rotor 18, four blade installation are in groove, and can in groove, be free to slide, water inlet and outlet joint 19 is installed on the pump stator 13, and pump base plate 15 is installed in the end face of pump stator 13, keeps the glade plane space of pump rotor 18.Center angle between water inlet and outlet joint 19,19 ' is installed is 115-125 °.Guaranteeing under any circumstance all has a slice with upper blade intake-outlet to be separated.Water seal 14 is installed in the pump stator 13, prevents that pump shaft from leaking.Blade 17 recited above adopts polyoxymethylene or polytetrafluoroethylene material, pump rotor 18 is when pump shaft 10 ' driven rotary, because action of centrifugal force, blade 17 skids off groove and is close on the internal surface of pump stator 13, be divided into four independently spaces, and owing to the suction effect is finished in the variation of spatial volume.

Compared with the prior art the utility model has the following advantages, and 1, direct current machine back end cover, rear casing All adopt synthetic material to make, omitted all parts of the necessary brush carrier part of general direct current generator, Therefore have simple in structure, compact, smooth running, use and maintenance is characteristics easily; 2, centrifugal wind The cooling duct from bottom to top, the bidirectional rotation requirement, vane pump, pump rotor, the blade that have satisfied pump all adopt Make with synthetic material, therefore the minimum point that the invalid loss of power is fallen has suction capacity, lift Height, applied widely, and certain rinse capability is arranged, and all kinds of pumps can't compare before having Superior function.
