Abstract
The utility model relates to a submersible sewage pump. The submersible sewage pump adopts the structure that a suction inlet is formed in a lower pump cover, and an impeller is arranged at the auction inlet. The pump is characterized in that movable blades are fixedly arranged on vanes of the impeller; and fixed blades fixed on the lower pump cover are arranged at the suction inlet, and the movable blades are matched with the fixed blades. The submersible sewage pump is reasonable and concise in structural design, small in vibration during work, anti-winding and high in efficiency.
Description
Technical field
The utility model relates to a kind of submerged sewage pump.
Background technique
Therefore in industrial production, submerged sewage pump all is widely used in every profession and trade because it can satisfy many specific uses, and along with application, the structure of submerged pump also obtain constantly along with improvement perfect.When submerged pump is worked, fibers such as the cotton yarn of Chang Youchang, the rope made of hemp, shred, or other similar substance twines impeller when submerged pump is worked, influence submerged pump to work normally, also easily causes the damage of motor after impeller is twined by fiber when serious.In order to prevent that fiber from twining impeller when submerged pump is worked, the technician has done structural improvement to such submerged pump, namely install rotary cutter additional at the suction port place, shredded earlier when making long objects such as fiber enter pump chamber, guarantee the proper functioning of submerged pump with this, in use obtain the user and approve preferably.But this submerged pump that has cutting device, its cutting device are external additional type structure, are split-type structural with impeller namely, are assembled by several parts, and submerged pump when work vibrations are bigger like this, still can occur during excesssive gap twining blocking phenomenon.
The model utility content
Technical problem to be solved in the utility model be overcome deficiency of the prior art and provide that a kind of reasonable in design is succinct, vibrations are little, antiwind during work, efficient is high submerged sewage pump.
The technical scheme in the invention for solving the above technical problem is: a kind of submerged sewage pump, have suction port at following pump cover place, and be provided with impeller at the suction port place, it is characterized in that: the blade at described impeller is set with cutting blade; Be provided with the ledger-plate that is fixed on the following pump cover at the suction port place, ledger-plate cooperates with cutting blade.
The blade tip of the utility model impeller extends to form cutting blade to the suction port outside.
The utility model also comprises cutterhead, and cutterhead comprises retainer ring and ledger-plate, and retainer ring is fixed on down on the pump cover, and ledger-plate is fixed on the retainer ring.
Gap between cutting blade described in the utility model and the ledger-plate is 0.3mm～0.5mm.
Ledger-plate described in the utility model is 1～5, is fixed on the retainer ring in the form of a ring.
The utility model compared with prior art has following advantage and effect: reasonable in design is succinct, vibrations are little, antiwind when working, efficient is high.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Referring to Fig. 1～Fig. 9, the utility model embodiment has suction port at following pump cover 1 place, is provided with impeller 3 at the suction port place.
Blade 7 at impeller 3 is set with cutting blade 4, specifically is, blade 7 ends of impeller 3 have extended to form cutting blade 4 to the suction port outside, and cutting blade 4 itself is made of blade 7 like this, is integral structure.
Cutterhead 2 and impeller 3 are at the suction port place up and down to be arranged.Cutterhead 2 comprises retainer ring 5 and ledger-plate 6, and retainer ring 5 is fixed on down on the pump cover 1, and ledger-plate 6 is fixed on the retainer ring 5, and ledger-plate 6 is fixed on down on the pump cover 1 by retainer ring 5, and ledger-plate 6 is arranged at the suction port place.Ledger-plate 6 quantity can be adopted as 1～5 according to the difference of Type of pump, be fixed in the form of a ring on the retainer ring 5, but also Equal round are arranged.Ledger-plate 6 cooperates with cutting blade 4, joins together to play dissection, and when cutting blade 4 during along with the blade rotation of impeller 3, ledger-plate 6 is united the impurity such as fiber that cutting enters suction port with cutting blade 4.
Gap between cutting blade 4 and the ledger-plate 6 is 0.3mm～0.5mm, and this gap is the perpendicular distance of cutting blade 4 and ledger-plate 6.When pump shaft rotates, between cutting blade 4 and ledger-plate 6, just form a cutting section like this, avoided influencing the proper functioning of pump.
Claims (5)
