Abstract
An annular membrane rotor pump consists of the annular membrane, a pump body, a pump shaft, an eccentric wheel, a front pump cover, a back pump cover and a shaft seal. A liquid inlet of the pump body is provided with a flexible slip sleeve device, and the slip sleeve inside the slip sleeve device is pressed towards an inner cavity of the pump body under the action of an elastic element. A gap still exists between the slip sleeve and the membrane outer circle under the limit of the limit position. When the membrane is lifted to the highest position and at the same time seals the liquid inlet and a liquid outlet, the instant communication between the liquid outlet and the liquid inlet is eliminated. In the subsequent operation, the two openings are always separate, which improves the cubage efficiency and conquers the bump of the water flow.
Description
Technical field
The utility model relates to a kind of displacement pump, and especially the barrier film rotor pump belongs to the pump valve technical field.
Background technique
At present, known no-leakage pump has magnetic force driven centrifugal pump and annular diaphragm rotor pump, specific efficiency is higher mutually with magnetic force driven centrifugal pump for the annular diaphragm rotor pump, but the shortcoming of annular diaphragm rotor pump is: when annular diaphragm rises to the extreme higher position under eccentric driving, seal liquid outlet, when annular diaphragm continues also no show complete closed of beat liquid entering hole, liquid outlet has instantaneous the connection with liquid entering hole, pressured fluid refluxes, at this moment, can only lean on the former cause liquid entering hole of liquid to come limit return flow to the inertia that liquid outlet flows, head pressure is big more, require the inertial flow of liquid entering hole big more,, restricted the generally use of this pump so just produced the decline of volumetric efficiency and the bump of current.
Summary of the invention
The purpose of this utility model is: propose a kind of novel annular diaphragm rotor pump, at liquid entering hole telescopic sliding bush apparatus is housed, be communicated with the instantaneous of liquid entering hole in order to eliminate liquid outlet, the raising volumetric efficiency also overcomes the bump of current.
In order to reach the above-mentioned purpose of stating, the utility model proposes a kind of annular diaphragm rotor pump, by annular diaphragm, the pump housing, pump shaft, eccentric wheel, front pump cover, rear pump cover and axle envelope are formed, and its special way is: the liquid entering hole of the pump housing is provided with telescopic sliding bush apparatus.
Scalable sliding bush apparatus in the embodiment of the present invention is to be made up of sliding sleeve, elastic element, gland.
Sliding sleeve in the embodiment of the present invention, the outer garden the when shape of its port can rise to the extreme higher position with annular diaphragm matches
Sliding sleeve in the embodiment of the present invention is equipped with positioning element, and it is inserted in the keyway in the pump housing liquid entering hole, prevents that sliding sleeve from rotating, and positioning element can be the garden pin, also can be flat key.
Sliding sleeve in the embodiment of the present invention, itself and annular diaphragm be the contacted port in garden outward, can be shaped on the cross-like rib, and the abate acute angle, in order to increase compression area, prevents to damage membrane surface.
Elastic element in the embodiment of the present invention can be a pressure spring, also can be rubber.
The advantage of new structure is: the sliding sleeve of liquid entering hole (9) stretches to the inner chamber of the pump housing (1) under the effect of elastic element (8), but be not pressed onto annular diaphragm (2), and it is still gapped between the barrier film, when barrier film rises to the extreme higher position, liquid entering hole and liquid outlet have been sealed simultaneously, make two mouthfuls not to be communicated with, barrier film continues operation, open liquid outlet, and liquid entering hole is sealed still, until opening liquid entering hole when barrier film, barrier film still continues liquid entering hole and liquid outlet are separated, and like this, has both kept annular diaphragm rotor pump self-priming performance good, do not have and leak, outside the advantages such as energy gas-liquid delivery, improve volumetric efficiency again, overcome the bump of current inertia.

Embodiment
Now specified as follows in conjunction with the accompanying drawings:
Fig. 1 is embodiment, annular diaphragm (2) is installed in the garden cylindrical hole of the pump housing (1), the cut water of annular diaphragm (5) is inserted in the guiding groove (6) of the pump housing, drive annular diaphragm by pump shaft (4) by eccentric wheel (3) and do garden shape translation, pump housing liquid entering hole is equipped with sliding sleeve (9), slide under the effect of spring (8), move to limit position to pump housing inner chamber, sliding sleeve is provided with locating stud (7), locating stud moves in the keyway (11) at pump housing liquid entering hole place, import gland (10) compresses the pump housing (1) by sealing gasket (12), and its inner is also as spring seat.
Fig. 2 is the situation that rises to the extreme higher position when annular diaphragm, and at this moment, annular diaphragm had both been sealed liquid outlet, has also sealed liquid entering hole simultaneously, and pressure medium can not reflux.
Fig. 3 is the enlarged view at liquid entering hole sliding sleeve position.
