Description
Technical field
The utility model belongs to field of energy source power, is related to a kind of self-priming pump configuration.
Background technology
Conventional centrifugal pump configuration, deteriorates in impeller eye or there are performance of centrifugal pump will be caused to drop during gas in pipeline
It is low, work is will be unable to when serious.To solve the above problems, there is self priming pump.The effect of self priming pump be by centrifugal pump impeller into
The air extraction of mouth, separates liquids and gases by self-priming impeller and discharges gas.Centrifugal pump inlet condition is substantially improved, is expanded
The big working range of centrifugal pump, improves the anti-cavitation performance of centrifugal pump.However, current self priming pump by radial impeller and before
Back shroud coordinates, and dedicated pipeline is set on housing to reach self-suction function, and there are self-priming effect is poor, assembling is smart for this structure
The defects of degree requires height, and foreign matter be easy to cause clamping stagnation failure.
Utility model content
In view of the above situation of the prior art, the purpose of this utility model is to provide a kind of self-priming pump configuration, to overcome or
It is poor to mitigate self-priming effect existing for current self-priming pump configuration, the defects of assembly precision requires high, easy clamping stagnation.
The above-mentioned purpose of the utility model is achieved through the following technical solutions：
A kind of self-priming pump configuration, including bearing (ball) cover, self-priming impeller and self-priming pump case, side opening wherein in bearing (ball) cover
Hollow shaft is turned on, hollow shaft is from main impeller import air-breathing, and self-priming impeller set is driven by axis and rotated on bearing (ball) cover, self priming pump
Housing is sleeved on self-priming impeller, has semi-moon shaped cavity to be used for oil-collecting in self-priming pump case, and self-priming impeller internal is used for for cavity
Aspirate gas-liquid, be with outside uniformly distributed radial vane be used for separate gas-liquid, afterbody has uniformly distributed sidewise hole, for it is rotational-molded into
Suction.
When self-priming impeller rotates, radial vane drives gas-liquid to be rotated, and under the influence of centrifugal force, liquid is thrown to
At semilune cavity on the periphery of self-priming impeller and self-priming pump case.The sidewise hole of self-priming impeller afterbody forms suction when rotated
Power, the gas of self-priming impeller internal is siphoned away and discharges housing.So formd under the suction of self-priming impeller from impeller inlet
To the circulation path of self-priming pump discharge.
Further, the sidewise hole can be 3~16, be usually 8, the number of sidewise hole can according to specific flow and
Rotating speed requirement is calculated.
Further, the semilune cavity can be 2~6, it is contemplated that oil-collecting effect and processability, are usually 2.
The advantages of self-priming pump configuration of the utility model is compact-sized, occupies little space, and matching requirements precision is low and not
Easy clamping stagnation, is aspirated by hollow shaft and bear box lumen passageway, and not only self-priming effect is good, but also improves pump housing heat dissipation,
Good lubrication can also be kept to bearing.
