Abstract
The utility model provides an improved structure of flexible vane pump. The structure is mainly used for solving the efficiency problem of the flexible vane pump. It is technically characterized by that two sides of rubber blade in the flexible blade pump are respectively equipped with an antifriction partition plate, and said antifriction partition plates are fixed on the rotor. When the pump runs, the friction power loss generated by the end faces of the rubber blades facing the front end cover and the rear end cover of the pump can be avoided.
Description
The utility model proposes a kind of improvement structure that improves the flexible blade pump efficiency.
The groundwork element of flexible paddle pump is a plurality of flexible blades of being made by rubber.Between the import and export of pump case inwall, be provided with a crescent shape piece, when these blades periodically touch with rotor rotation in the pump case active chamber or leave the crescent shape piece, blade borrows the resiliently deformable of itself that the volume between two blades and the crescent shape piece is increased and decreased, and forms the suction liquid effects of pump.Flexible paddle pump can keep suction liquid incessantly, touches the seal degree of pump chamber during mainly by the rotation of these blades and decides.Make pump obtain good sealing, the blade that is installed in the pump chamber must not gappedly exist.Therefore, when these blades rotate, must produce surface friction drag under load, increase the power loss of pump, reduce the efficient of pump with pump case inwall and front and rear cover.The inefficient shortcoming of flexible paddle pump that Here it is.
Propose the purpose of this utility model and provide a kind of improvement structure that improves the flexible blade pump efficiency.
Finish method of the present utility model and be between the both sides of rubber tree leaf and front and rear cover and respectively add an anti-attrition dividing plate, and be separately fixed at screw on the both sides of rotor.Like this, when rotor rotates, owing to be fixed on epitrochanterian rubber tree leaf and two anti-attrition dividing plates rotate with the rotor synchronous speed, thereby do not have relative movement between them, just can not produce friction torque between blade and the end cap like this, thereby prevent the frictional power loss of blade end cap.
The structure that in flexible paddle pump, increases by two anti-attrition dividing plates that the utility model proposed, when its main advantage is that it has overcome the rubber tree leaf rotation to the surface friction drag that front and rear cover produced of pump, and can prevent mutual wearing and tearing between blade and the end cap, reduced the power loss of pump.It improves about 20% than the efficient of general flexible paddle pump, has solved the inefficiency problem of flexible paddle pump effectively.
The embodiment of model utility as shown in drawings.
The utility model has two accompanying drawings, in order to the structure characteristic and the working state of rubber tree leaf in pump case thereof of explanation flexible paddle pump.
Fig. 1 is the transverse sectional view of flexible paddle pump.It is made up of rubber tree leaf (1), pump case (2), two anti-attrition dividing plates (3), rotor (4), set screw (5) and front and rear cover (6) etc.
Fig. 2 is the A-A longitudinal sectional view of pump among Fig. 1.
As can be seen from Figure 2 each rubber tree leaf (1) rotates with the rotation two of rotor (4) with the anti-attrition dividing plate (3) of both sides, and they do not touch the front and rear cover (6) of pump.
Claims (1)
- A kind of flexible paddle pump, constitute by pump case, rotor, rotating shaft, rubber tree leaf, anti-attrition dividing plate etc., it is characterized in that, respectively add an anti-attrition dividing plate (3) between the both sides of rubber tree leaf in flexible paddle pump (1) and the front and rear cover (6), and it is fixed on the both sides of rotor (4) respectively with screw (5).
