The oil pump comprises a shell, a stator, a rotor and a rotating shaft, wherein the stator is arranged in the shell, the rotor is arranged in the stator and matched with the stator, and the rotating shaft is inserted in the shell and connected with the rotor. The end portion of the rotating shaft is located outside the shell. The oil pump further comprises a pump element arranged on the end portion of the rotating shaft in a sleeved mode, and the pump element is provided with a first inlet and a first outlet. The shell, corresponding to the outlet in the pump element, is provided with a second outlet, and the first outlet is communicated with the second outlet. Compared with the prior art, due to the fact that the stator and the rotor in the oil pump do not need to be installed outside the pump body independently, the installation space of the complete pump is saved, and outside contamination to oil products is avoided; a pipeline is shortened, cooling efficiency is improved, and the service life of the oil pump is longer when a 110/60 HZ power source is used in the oil pump.

Description

Oil pump
Technical field
The utility model relates to a kind of oil pump, specifically a kind of full immersed type oil pump.
Background technique
At present, domestic power supply is unified is single phase alternating current 220V/50HZ, but because the power supply voltage of certain areas or country is 60HZ, such as Japanese power supply is single phase alternating current 110V/50HZ, 110/60HZ, the motor of the 110V/50HZ that Ruo Jiang China produces is used on the power supply of 110/60HZ, can add that speed motor is aging even to be burnt.
Secondly, central air-conditioner unit for the requirement of cooling oil pump wherein towards compact structure, without leaking, the development of pollution-free, non-maintaining direction.
So for adapting to domestic and international market and unit installation requirements, need to research and develop a can be interchange 110V at power supply voltage, frequency is the full immersed type oil pump of 60HZ work.
Model utility content
The purpose of this utility model is to provide a kind of oil pump, so that oil pump while using on the power supply of 110/60HZ, has longer working life.
To achieve these goals, mode of execution of the present utility model has designed a kind of oil pump, comprises housing, is arranged on stator in described housing, is arranged on the rotor that coordinates with described stator in described stator, inserts the interior rotating shaft being connected with described rotor of described housing; Wherein, the end of described rotating shaft is positioned at outside described housing;
Described oil pump also comprises: be set in the pump element of described roller end, described pump element has first import and one first outlet;
The second outlet is offered in the first outlet on the corresponding described pump element of described housing, and described the first outlet is communicated with described the second outlet.
Mode of execution of the present utility model in terms of existing technologies, because stator and the rotor of oil pump inside do not need to be independently arranged on outside the pump housing, thereby saved the installing space of whole pump, the pollution of having avoided oil product to be come from the outside, and shortened pipeline, improved cooling effectiveness.When oil pump is used on the power supply of 110/60HZ, there is longer working life.
Preferably, described pump element is inside engaged gear pair.Because pump element adopts inside engaged gear pair, because inside engaged gear is to there being very strong self-priming performance, make the conveying of liquid more steadily, pulsating movement free, vibrates littlely, and noise is low, has further improved the working life of whole pump.
Preferably, described oil pump also comprises: be set in the pump element cover plate outside described pump element, the first import on the corresponding described pump element of described pump element cover plate is offered the second import, described the second import and described the first import conducting.Owing to being provided with pump element cover plate on pump element, by pump element cover plate, can protect pump element, avoid foreign matter to enter in pump element, affect transportation performance.
Preferably, the surface of contact of described rotating shaft and described housing is provided with bearing.Owing to being provided with bearing between rotating shaft and the surface of contact of housing, i.e. rotating shaft is slidably connected by bearing and housing, and the frictional force in the time of can reducing rotating shaft rotation by bearing and between housing, avoids rotating shaft and housing to wear and tear.
Preferably, in order to meet the demand in market, described bearing can adopt rolling bearing or sliding bearing.
Preferably, described housing is provided with suspension ring.Because housing is provided with suspension ring, the lifting of being convenient to whole pump by suspension ring is installed.
Accompanying drawing explanation
Fig. 1 is the structural representation of the oil pump of the utility model the first mode of execution.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing, each mode of execution of the present utility model is explained in detail.Yet, persons of ordinary skill in the art may appreciate that in each mode of execution of the utility model, in order to make reader understand the application better, many ins and outs have been proposed.But, even without these ins and outs and the many variations based on following mode of execution and modification, also can realize each claim of the application technological scheme required for protection.
The first mode of execution of the present utility model relates to a kind of oil pump, as shown in Figure 1, comprises housing 1, is arranged on stator 2 in housing 1, is arranged on the rotor 3 that coordinates with stator 2 in stator 2, inserts the interior rotating shaft 4 being connected with rotor 3 of housing 1; Wherein, the end of rotating shaft 4 is positioned at outside housing 1.
In addition, the oil pump of present embodiment also comprises: the pump element 5, the pump element 5 that are set in rotating shaft 4 ends have first import 6 and one first outlet 7.
Wherein, first on housing 1 respective pump element 5 outlet 7 offers the second outlet 8, the first outlets 7 and second and exports 8 and be communicated with.
In the present embodiment, because stator 2 and the rotor 3 of oil pump inside do not need to be independently arranged on outside the pump housing, thereby saved the installing space of whole pump, the pollution of having avoided oil product to be come from the outside, and shortened pipeline, improved cooling effectiveness.When being used on the power supply of 110/60HZ, oil pump there is longer working life.
It is worth mentioning that, in the present embodiment, pump element 5 adopts inside engaged gear pair.Because pump element 5 adopts inside engaged gears pair, because inside engaged gear is to there being very strong self-priming performance, make the conveying of liquid more steadily, pulsating movement free, vibrates littlely, and noise is low, has further improved the working life of whole pump.
