Description
Technical field
The utility model belongs to fluid machinery technical field, is related to a kind of deep well pump.
Background technology
Deep well pump is that motor and water pump direct-connected integrated pull the plug the water lift equipment of work, has simple in structure, unit effect
Rate is high, and noise is small, safe and reliable to operation, advantage convenient to install and maintain.Must be hydraulically full in suction line and pump before turn on pump, it opens
Impeller high speed rotation after pump, liquid therein rotate together with blade, under the influence of centrifugal force, fly away from impeller and penetrate outward
Going out, the liquid of the injection speed in pump case diffuser casing is gradually slack-off, and pressure gradually increases, and is then flowed out from pump discharge discharge pipe,
At this time at blade center due to liquid be thrown toward around and formed both without the vacuum low-pressure area of the not no liquid of air, liquid pool
In liquid flowed under the action of the atmospheric pressure of pond face pump in.
The structure of deep well pump its motor section on the market is generally monoblock type at present, is equivalent to motor and control panel is put together
It is placed in shell, in order to which motor can effectively radiate, cooling oil is perfused in shell, therefore control panel is also soaked in cooling oil
In, and micro water is usually contained in cooling oil, its internal water, which is easy to assemble on control panel, after prolonged use causes
Line fault reduces the service life of deep well pump, and monolithic construction repair and replacement inconvenience must be by cooling in dismounting
Oil is poured out, and further, guide vane shell is generally single wall in impeller assembly, easy to wear to make under water pump service life reduction efficiency
Drop.
Invention content
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, and providing one kind can be effectively increased
The deep well pump of its service life.
The purpose of this utility model can be realized by following technical proposal：A kind of deep well pump, including motor section and the pump housing
Portion, wherein the motor section mainly by shell and the motor form for being set to enclosure interior, is provided in the pump housing portion
Several impeller assemblies being fixedly connected with motor shaft, which is characterized in that the lower section clearance fit of the shell is arranged with installation end, institute
If to be tightly connected and wearing bolt stem fastening by radial between the shell and installation end stated, the bottom surface in the shell opens up
The outlet hole for having and being connected to inside installation end；
The impeller assembly includes guide vane shell and the impeller that is provided in guide vane shell, the opening edge of the guide vane shell
Inside bending makes its thickening form reinforcing rib, and the impeller includes overhead gage, lower baffle and is set to blade between the two,
It is an integral structure between the overhead gage and blade and the blade passes through overhead gage punch forming, lower baffle welding
In the lower section of blade.
The advantages of this deep well pump is：Control panel is fixed on inside installation end, is passed through by outlet hole with the connecting line of motor,
Being sealed with fluid sealant at outlet hole prevents the cooling oil seepage of enclosure interior, passes through sealing ring on the contact surface of shell and installation end
It seals and wears bolt fastening by radial, the design of the structure can make control panel be respectively placed in different accommodating cavities from motor
Interior, enclosure interior is perfused with cooling oil and will not leak into installation end, and wherein installation end can prevent outside by sealing ring
Fluid seepage, increase the service life of deep well pump, and installation end need to only be dismantled in the maintenance of later stage control panel and be
Can, keep its repair more convenient；
Further, the setting of reinforcing rib can prevent guide vane shell edge abrasion from reducing efficiency, and overhead gage passes through punching press
Make blade straight forming, relative to traditional welding structure, effectively raises production efficiency.
In a kind of above-mentioned deep well pump, sealed by fluid sealant at the outlet hole.
Compared with prior art, this deep well pump has the advantages that the service life is longer.
