Abstract
The utility model provides a novel impeller rotor pump, having the main technical characteristics that: a gap D between a pump body and a rotor is less than or equal to 1 mm; an inlet center line and an inlet center line of a pump are on the same axial line with a rotor center line; the outlet and the inlet of the pump are in a parallel structure. The utility model has the advantages of novel structure, simple process, low noise, enough pressure, stable working state, high working efficiency, etc.
Description
Technical field:
The utility model relates to a kind of blade wheel roller pump of oil field oil pumping usefulness, particularly a kind of novel impeller rotor pump.
Background technique:
At present, be used for the of a great variety but most of pumps of the oil well pump in oil field to taking out the poor effect of tack coat.Particularly there was the people to invent blade wheel roller pump in these several years, is used for the oil field and takes out tack coat or oil, gas, water mixed delivery.For example the patent No. once provided the blade wheel roller pump of a kind of oil, gas, water mixed delivery for 03211362.5 patent, this blade wheel roller pump is in actual applications because the excesssive gap between the rotor and the pump housing, cause the underpressure of pump, unstable working condition, and noise is big, has destroyed normal operation circumstances.Again since its import and row mouthful all vertically upward, the center of import and row mouthful and the pump housing is at same axis.Therefore, can cause flow of fluid to produce eddy current, produce flow of fluid in the upper cavity of the pump housing, resistance increases, unstable working condition.
Summary of the invention:
The purpose of this utility model is the deficiency that exists in the above-mentioned technology, and a kind of novel impeller rotor pump is provided, and not only noise is little for it, pressure foot, stable working state, and efficient height.
The purpose of this utility model is achieved in that and comprises the pump housing, blade, rotor, rotor shaft, it is characterized in that, and the pump housing and gap between rotor D≤1mm, the import of pump, center line of discharge and rotor centerline are at same axis.And the import of pump, the center line of outlet are higher than the center line of the pump housing.Delivery side of pump and import are parallel structure.
The utility model has the advantages that, novel structure, technology is simple, and it is little to have a noise, pressure foot, stable working state, characteristics such as working efficiency height.
Description of drawings:
Fig. 1 is the utility model internal structure schematic representation.
Embodiment:
Below in conjunction with accompanying drawing present embodiment is described further:
As shown in Figure 1, the clearance D≤1mm between the pump housing 1 and the rotor 3, the import 5 of the pump housing is parallel structure with outlet 6.The center line of import 5 and outlet 6 and roller 2 center lines are at same axis.And the center line of import and outlet is higher than the center line of the pump housing, and the difference of roller center line and pump housing center line is represented with H.1 li roller axle 2 is housed fixedly at the pump housing, fixed rotor 3 on roller axle 2, and blade 4 is installed in the groove of rotor 3.
Its principle is that the more little pressure in the gap of the pump housing and rotor is big more.In same structure, under the situation of same power, when flow reduced, pressure increased, and the import of pump produces eddy current with the parallel flow that reduces of outlet in cavity, avoid causing liquid flowing resistance to increase.
Claims (1)
