Description
Technical field
The utility model relates to sewage pump under a kind of liquid.
Background technique
Sewage pump product under existing liquid, the main running clearance adopting high and low pressure chamber in centrifugal pump impeller and the pump housing, realizes sealing with seal ring, there is following shortcoming in it: centrifugal pump impeller, when pumping containing solid matter, especially when pumping the liquid containing fibre object, easily there is runner blocking; After long-play, in sewage occasion, pump seal ring portion position meeting Fast Wearing, causes pump performance to decline; Centrifugal pump is when pumping the liquid containing gas, and pump can stop, and causes using.
Summary of the invention
The utility model object is to solve the problem, and provides sewage pump under a kind of liquid, is specifically realized by following technological scheme:
Sewage pump under a kind of liquid, comprise the pump housing, motor, transmission shaft, impeller and the pump cover that longitudinally arrange, the described pump housing comprises and is positioned at the carrier board above oilysewage surface, the coupling body be arranged on carrier board, the underwater case that is connected to the drive shaft sleeve on the downside of carrier board and is connected with described drive shaft sleeve lower end, described motor is longitudinally arranged at the upper end of the pump housing, and the rotating shaft of motor is connected with the transmission shaft being positioned at drive shaft sleeve by coupling body; The bottom of described underwater case has the lower end cap of bottom and transverse side opening, described pump cover to be arranged in underwater case and to be positioned at the top of described lower end cap, delivery chamber is formed between described pump cover and lower end cap, described transmission shaft enters in delivery chamber through described pump cover, described impeller is connected to one end that described transmission shaft is positioned at delivery chamber, and between the lower side of described impeller lower end cap inner side surface corresponding thereto, there is gap, thus formed without phyllocyst between impeller and the inner side surface of described lower end cap; Bottom described lower end cap, the opening of transverse side is respectively water intake, water outlet.
Sewage pump under described liquid, it designs further and is, the middle part of described pump cover is upwards swelled, thus forms sub-propeller chamber, is provided with the sub-propeller with described impeller coaxial rotation in this sub-propeller chamber.
Sewage pump under described liquid, it designs further and is, described impeller comprises the center of rotation be connected with transmission shaft and the some blades be distributed in around center of rotation, described blade comprises near the joint of center of rotation and the homework department away from center of rotation, and the width autorotation center of described joint progressively increases laterally and is transitioned into described homework department; The part that described lower end cap inner side surface is relative with described homework department is provided with the groove of annular, thus increases the described space without phyllocyst, and forms circular flow region at described groove.
Sewage pump under described liquid, it designs further and is, described water intake, water outlet are connected to intake pipe, outlet pipe, and described intake pipe is the straight tube to downward-extension, and described outlet pipe is the bend pipe being bent upwards and extending to above carrier board.
The utility model impeller below tool for solid matter pass through without phyllocyst, can not block containing during solid matter pumping; There is not seal ring between the utility model impeller and the pump housing, thus there will not be the problem because pump seal ring portion position meeting Fast Wearing causes pump performance to decline; The utility model can pump the sewage containing gas.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with Figure of description and embodiment, the utility model is further described.
Under this liquid, sewage pump comprises the pump housing 1, motor 2, transmission shaft 3, impeller 4 and the pump cover 5 that longitudinally arrange, the pump housing 1 comprises and is positioned at the carrier board 11 above oilysewage surface, the coupling body 12 be arranged on carrier board, the underwater case 14 that is connected to the drive shaft sleeve 13 on the downside of carrier board and is connected with drive shaft sleeve lower end, motor 2 is longitudinally arranged at the upper end of the pump housing, and the rotating shaft of motor is connected with the transmission shaft 3 being positioned at drive shaft sleeve by coupling body 12; The bottom of underwater case 14 has the lower end cap 141 of bottom and transverse side opening, pump cover 5 to be arranged in underwater case 14 and to be positioned at the top of lower end cap, delivery chamber 6 is formed between pump cover 5 and lower end cap 141, transmission shaft 3 enters in delivery chamber through pump cover, impeller is connected to one end that transmission shaft 3 is positioned at delivery chamber, and between the lower side of impeller lower end cap inner side surface corresponding thereto, there is gap B, thus formed without phyllocyst 61 between impeller and the inner side surface of lower end cap; Bottom lower end cap, the opening of transverse side is respectively water intake 7, water outlet 8.
The middle part of pump cover 5 is upwards swelled, thus forms sub-propeller chamber, is provided with the sub-propeller 9 with impeller coaxial rotation in this sub-propeller chamber.
Impeller 4 comprises the center of rotation be connected with transmission shaft and the some blades 41 be distributed in around center of rotation, blade comprises near the joint 411 of center of rotation and the homework department 412 away from center of rotation, and the width autorotation center of joint progressively increases laterally and is transitioned into homework department; The part that lower end cap inner side surface is relative with homework department is provided with the groove 111 of annular, thus increases the space without phyllocyst, and forms circular flow region at groove.
Water intake, water outlet are connected to intake pipe 15, outlet pipe 16, and intake pipe is the straight tube to downward-extension, and outlet pipe is the bend pipe being bent upwards and extending to above carrier board.The diameter of intake pipe, outlet pipe is to be directly proportional to the particulate matter in sewage without the height of phyllocyst.
The utility model impeller below tool for solid matter pass through without phyllocyst, can not block containing during solid matter pumping; There is not seal ring between the utility model impeller and the pump housing, thus there will not be the problem because pump seal ring portion position meeting Fast Wearing causes pump performance to decline; The utility model can pump the sewage containing gas.
