Abstract
The utility model discloses a rotor oil pump with low production cost and low difficulty in process, including a pump shell (1) and a hub (2). A circular internal cavity is arranged in the pump shell (1); the hub (2) is wholly round which is arranged on the internal cavity wall of the pump shell (1).
Description
Technical field
The utility model relates to a kind of structural member of rotor oil pump, particularly a kind of rotor pump body.
Background technique
Existing rotor pump body comprises pump case, lining, and lining is spliced by multi-section circular arc shape liner, and the pump case inner chamber is provided with corresponding multi-section circular arc kiss and connects curve.Wherein the required material property of circular arc liner requires height, and processing technology requires high, and the material of domestic production does not at present all reach usage requirement, so cost of production is very high.
Summary of the invention
The purpose of this utility model provides the rotor pump body that a kind of cost of production is low, technology difficulty is low.
For achieving the above object, the utility model by the following technical solutions: a kind of rotor pump body, comprise pump case, lining, described pump case is provided with round cavity, described lining is a unitary circular, lining is located on the internal chamber wall of pump case.
In above-mentioned technical solution, lining adopts the unitary circular structure, compares with the lining that multi-section circular arc shape liner is spliced, and its processing technology requires low, and required material property requires also can reduce greatly, so cost of production can reduce greatly.
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the general structure schematic representation of the utility model rotor pump body.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, the utility model rotor pump body comprises pump case 1, lining 2, and described pump case 1 is provided with round cavity, and described lining 2 is a unitary circular, and lining 2 is located on the internal chamber wall of pump case 1, and lining 2 adopts teflon to make.Through test, its performance and working life reach usage requirement fully, thereby cost of production, technology difficulty are reduced greatly.
Claims (2)
1, a kind of pump housing of rotor oil pump comprises pump case (1), lining (2), and it is characterized in that: pump case (1) is provided with round cavity, and lining (2) is a unitary circular, and lining (2) is located on the internal chamber wall of pump case (1).
2, the pump housing of rotor oil pump according to claim 1 is characterized in that: lining (2) adopts teflon to make.
