Abstract

The utility model provides a micro large flow submersible pump, belonging to the submersible pump, which connects a rotator and a stator of an electric motor with an impeller wheel directly. An oil reservoir is arranged between the electric motor and a pump body, causing a double-end sealing ring to be embedded in the oil reservoir, and a double-tongue water seal is arranged on the double-end sealing ring and above the impeller wheel, reaching the goal of ternary protections. The pump has easy carry, and the utility model is suitable for undervoltage environment for mountain areas, countryside, etc.

Description

The miniature big flow pump of diving

The utility model provides a kind of miniature big flow pump of diving, and belongs to submersible pump.

Pump has water source and electric power just can use easily and flexibly as long as dive, need not to fix, install, but the technical requirements height of the pump of diving, the standard of safe leakproof is strict.At present China rural area, mountain area need especially that volume is little, the power foot, lift is high, flow is big, leakproof is safe and reliable, the product that has motor to protect automatically, be difficult for burning, and this is badly in need of the technical problem that solves just on market.

It is little that the purpose of this utility model provides a kind of volume, the power foot, and flow is big, and full-automatic overtemperature protection system is arranged, the reliable miniature immersible pump of leakproof.

The technical solution of the utility model is: have motor, the miniature big flow that the pump housing and impeller are formed is dived in the pump, the axle that motor changes stator 10 is impeller 5 directly, forms integratedly, between the commentaries on classics stator 10 and the pump housing 3 oil pocket 9 is set, double end seal ring 8 is placed between motor, the pump housing and the oil pocket, two tongue water seals 7 are equipped with, with the back pressure leakproof in side under double end seal ring 8 on the impeller 5, the motor of the pump of diving is worked under water can play triple leakproof effects, and having only 0004m ³Less volume in hold the motor that power is 900W, produce the effect of miniature big flow.

The utility model compared with prior art has following advantage:

1 adopts motor and impeller directly to connect forms integrated form, and volume is little, only is 0.0055m ³, maneuverability is easy to carrying;

2 efficient height, power reaches 900W, and flow is big, and peak rate of flow is not less than 25m ³/ hour;

3 are provided with two back setting-out envelopes, and both bilge water resisting silt made hydraulic pressure increase again and holds main shaft automatically tightly the infringement of machinery, prevented that sewage from entering oil pocket, had triple protection against leakage effects.

4 adopt the responsive protecting component of bimetallic strip, reach full-automatic protection purpose.

Be illustrated below in conjunction with accompanying drawing:

Accompanying drawing is the utility model structural drawing.

Among the figure, the 1-wiring terminal, the 2-motor protecter, the 3-pump housing, the 4-joint, the 5-impeller, the 6-pump cover, the two tongue water seals of 7-, 8 double end seal rings, the 9-oil pocket, 10 change stator, 11-cable.

Shown in the figure, motor protecter 2 is put in the casing in motor loam cake hole, it is contacted with stator line bag, wiring terminal 1 connects cable 11 lighting outlets, and other end and winding master pay and be connected together, and promptly are connected in the circuti diagram and can shield.Motor protecter 2 operating temperatures are 105 ℃, and reset temperature is 75 ℃ ± 5 ℃, and operating voltage is 170V.

Double end seal ring 8 is to be made by the aluminium sesquioxide stupalith, and wear resistance is good, at concentration＜3%; can work under the sewage mud of medium＜5%; add the triple protection that carries lubricating grease between two back setting-out envelopes (preceding tongue is antifouling, and back tongue is anti-presses) two tongues, can under varying environment, use.

Claims

1, the latent pump of a kind of miniature big flow, have motor, the pump housing and impeller, it is characterized in that, motor changes the direct impeller (5) of axle of stator (10), between the commentaries on classics stator (10) and the pump housing (3), be provided with oil pocket (9), double end seal ring (8) is placed to be changeed between stator, the pump housing and the oil pocket, and two tongue water seals (7) are equipped with in side under double end seal ring (8) on the impeller (5).

2, according to the latent pump of the described miniature big flow of claim 1, it is characterized in that double end seal ring (8) is made for the aluminium sesquioxide stupalith.
