Description
Technical field
The utility model relates to industrial pump, refers more particularly to a kind of one step single sucking formula without block self-pumping pump.
Background technique
Horizontal self-sucking pump is applicable to petroleum and petrochemical industry, oil refinery, power station, chemical industry, pipeline supercharging and industrial and mineral enterprises and institutions for, draining, Applicable scope and of many uses, different according to the liquid of the demand of user or fed sheet of a media, the material of self-priming pump contact liq part is optional cylinder iron, cast steel, 1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti, 316,316L, Ti.
The working principle of horizontal self-sucking pump is: first in pump chamber, fill water before self-priming pump starts, after starting, impeller High Rotation Speed makes the water in impeller channel discharge volute, such pump intake just forms vacuum, air in intake line enters in pump, mix with the water in pump chamber, the gas-liquid separation chamber on pump chamber top is expelled to through impeller, due to the unexpected increase of discharge area, air water produces and is separated, the air of separating out is discharged by water pump outlet pipe road, the water separated is due to than great, the return port sunk bottom pump case flows to impeller outer edge, the air continuing to come with suction pipe mixes mutually, iterative cycles like this, gradually by the air emptying in suction line, realize normal pumping operation mode.
The axial force direction produced for electric machine main shaft in the working procedure of self-priming pump routine is unfixed; be easy to cause the non-driven-end bearing temperature of motor very high; although motor belt motor does not shut down injection-discharge oil device; but the note oil extraction cycle is very short; not in placely just easily to burn out a bearing once safeguard; when motor bearings breaks down, motor just looks like with very large load stall, and electric current straight line rises certainly will cause that motor winding is overheated also to be burnt out.The investigation of and process operating mode on-the-spot through use repeatedly and tracking, the axial force impact that the bearing of motor anti-drive end bears compared with drive end is relatively large, also most easy burn-out.
Application number is that the utility model patent of CN201220464141.5 discloses a kind of horizontal self-sucking pump, the machine envelope partial design of this model utility is without axle sleeve, set up double mechanical seal, as everyone knows, after the mechanical seal running certain hour of self-priming pump, seal face produces attrition value on axial length, reduces the sealability of self-priming pump; This model utility is provided with a bearing at the anti-drive end of motor, and due to not fixing of radial force and axial force, the bearing temperature of the anti-drive end of motor is very high, easy burn-out.
