Abstract
The utility model relates to a novel self-suction sewage removal pump, comprising a motor, a pump shell, a pump cover and an impeller. The novel self-suction sewage removal pump is characterized in that a motor shaft of the motor which is a long shaft passes through the pump cover and is connected with the impeller; one side of the impeller close to the pump cover is provided with back vanes; the pump cover and the back vanes on the impeller are matched with small clearance; the pump cover is provided with an O-shaped sealing ring which is hermetically connected with the pump shell in the radial direction. The novel self-suction sewage removal pump has the advantages of greatly simplifying the structure of the self-suction sewage removal pump, shortening the axial dimension, saving the installation space of a pump chamber, lightening the weight of the whole pump, saving the cost of the set, improving the concentricity of rotor parts and facilitating the assembly and disassembly as the motor and the pump have the same shaft, and balancing a part of axial force, avoiding the waterpower loss which is caused by the rotational flow impact of the upper part of the impeller and improving the efficiency of the water pump as the back vane structure is added.
Description
Technical field
The utility model relates to a kind of self-priming pollution discharge pump, particularly a kind of self-priming pollution discharge pump.
Background technique
Self-priming pollution discharge pump (see figure 1) is generally horizontal band console parts 15 structures at present, and motor 11 is by coupling 13 driven pump rotors.Complicated integral structure, mounting or dismounting trouble and cost are higher; Motor shaft 12 connects by coupling 13 with pump shaft 14, and concentricity is poor.Pump chamber 16 is bigger, and there is bigger hydraulic loss in impeller 17 tops because of eddy flow impacts, and have seriously reduced the efficient of water pump, therefore demands inventing a kind of self-priming pollution discharge pump that can overcome above-mentioned defective urgently.
Summary of the invention
The purpose of this utility model is to solve the problem that self-priming pollution discharge pump in the prior art adopts horizontal band console parts and utilizes the existing complicated integral structure of coupling driven pump rotor, and a kind of self-priming pollution discharge pump is provided.The utility model designs a kind of self-priming pollution discharge pump, comprise motor, pump case, pump cover, impeller, it is characterized in that: the motor shaft of motor is a major axis, the motor shaft of motor passes pump cover and connects impeller, on nearly pump cover one side of impeller, back blade is arranged, little Spielpassung is arranged between the back blade on pump cover and the impeller, have 0 RunddichtringO to be connected on the pump cover with the pump case radial seal.The utility model has the advantages that and simplified self-priming blowdown pump structure greatly, shortened axial dimension, saved the pump house installing space; Alleviate whole pump weight, saved the unit cost; Pump is coaxial, and the concentricity of rotor part improves, and mounting or dismounting are convenient; Set up back vane structure, both balance section axial power, also avoided upper impeller because of eddy flow impacts the hydraulic loss that causes, improved pump efficiency.
Description of drawings
Accompanying drawing 1 is the prior art constructions schematic representation,
Accompanying drawing 2 is a structural representation of the present utility model,
Below in conjunction with drawings and Examples the utility model is elaborated,
Embodiment
By improvement to self-priming pollution discharge pump structure, on general self-priming pollution discharge pump basis, remove horizontal band console parts 15, shorten pump shaft 14 and and motor shaft 12 unite two into one and promptly utilize the motor shaft 5 that extends.Both made things convenient for mounting or dismounting, it is heavy to have alleviated pump, also provides cost savings, and has improved the concentricity and the pump efficiency of rotor part simultaneously.Have tangible economic benefit and high social.
Claims (1)
