Abstract
The utility model relates to the technical field of water pumps, in particular to a novel short-connection efficient pump. The novel short-connection efficient pump is characterized by comprising a motor cover, a motor shell, an oil chamber, a mechanical seal, a pump cover, an O ring, an impeller, a pump block, an impeller catch, a pump shaft and a short connecting sleeve. The novel short-connection efficient pump is characterized in that the short connecting sleeve is arranged on the pump shaft; the short connecting sleeve and the pump shaft are connected to form a sealing surface for balancing pressure and stability between the pump cover and the oil chamber, turbulence impact of a medium on a pump body overcurrent part is reduced, the hydraulic loss of the pump is reduced, and the working efficiency of the pump is improved.
Description
Technical field
The utility model relates to the pump technology field, especially a kind of novel short high effective pump that connects.
Background technique
Traditional water pump is after start work, and the pressure of inner chamber can raise between the pump cover and the pump housing, and sealing needs often to change; Otherwise can produce breakage, equipment can't be worked, and the pump housing is crossed the generation turbulent flow impact that fails to be convened for lack of a quorum; Increase the hydraulic loss of pump, the efficient of pump is reduced.
Summary of the invention
For addressing the above problem, the utility model provides a kind of novel short high effective pump that connects, said a kind of novel short high effective pump that connects; It is characterized in that, comprising: motor cover 1, motor casing 2, grease chamber 3, mechanical seal 4, pump cover 5, O type circle 6, impeller 7, pump seat 8, impeller catch 9, pump shaft 10, short connecting sleeve 11, said a kind of novel short high effective pump that connects; On pump shaft 10, be provided with short connecting sleeve 11; Said short connecting sleeve 11 is connected into sealing surface with pump shaft 10, and pressure and stability between balance pump cover 5 and the grease chamber 3 reduce medium and impacts at the turbulent flow that pump housing overcurrent partly produces; Reduce the hydraulic loss of pump, improved pump work efficient.
The beneficial effect of the utility model is: 1. pressure between balance pump cover and the grease chamber guarantees the pump shaft balance.2. change pump performance, improved the efficient of pump.3. prolong the working life and the working stability of pump.
Description of drawings
Fig. 1 is the utility model schematic representation.
Wherein: motor cover 1, motor casing 2, grease chamber 3, mechanical seal 4, pump cover 5, O type circle 6, impeller 7, pump seat 8, impeller catch 9, pump shaft 10, balance connecting sleeve 11.
Embodiment
As shown in the figure; Said a kind of novel short high effective pump that connects is provided with short connecting sleeve 11 on pump shaft 10, said short connecting sleeve 11 is connected into sealing surface with pump shaft 10; Pressure and stability between balance pump cover 5 and the grease chamber 3; Reduce medium and impact, reduce the hydraulic loss of pump, improved pump work efficient at the turbulent flow that pump housing overcurrent partly produces.
