Description
Technical field
The utility model relates to a kind of vacuum pump.
Background technique
Vacuum pump comprises dry screw vacuum pump, water ring pump, reciprocating pump, slide valve pump, sliding vane rotary pump, Roots pump and diffusion pump etc., these pumps are requisite main force pump kinds in Chinese national economy every profession and trade application vacuum technology process, and applying maximum in current industry is Nash hytor and rotary-vane vaccum pump etc.The shortcomings such as this type of pump exists low vacuum, and operating noise is large, and energy consumption is high, generally all need out one one for subsequent use, this adds equipment investment and operating cost virtually.In recent years, along with China's sustain economic high speed development, vacuum pump associated downstream application industry keeps quick growth, designs that a kind of structure is simple, degree of vacuum is high, energy consumption is low, and the vacuum pump that noise is little is significant to realizing developing fast sustainedly and stably of economy.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, degree of vacuum is high, and energy consumption is low, the vacuum pump that noise is little and new multistage vacuum pump.
The technical solution adopted in the utility model is: a kind of vacuum pump, comprise the straight tube shape pump housing, the two ends of the pump housing are respectively equipped with suction port and air outlet, a high-speed electric expreess locomotive is respectively equipped with at two ends in the pump housing, the rotating shaft of two high-speed electric expreess locomotives is relative, sense of rotation is contrary, the rotating shaft of two high-speed electric expreess locomotives is respectively provided with more than 2 impellers, between adjacent fan-wheel, is provided with stator, pump housing center is provided with the support for supporting rotation shaft of high-speed motor.
For cooling in the situation of working long hours to above-mentioned vacuum pump, described vacuum pump also comprises a cold-water tank, and one end of cold-water tank connects intake pipe, and the other end is connected to the suction port end of the pump housing by pipeline, and joint is provided with shell fragment.Cooling water forms water smoke and enters the pump housing after shell fragment, lowers the temperature to motor and the pump housing, and discharges through air outlet.
Further, described pump housing wall is provided with temperature transducer, and temperature signal is sent to temperature controlling instrument by temperature transducer, and control signal is sent to relay by temperature controlling instrument, the opening and closing of Control cold-water tank pipeline.
Described high-speed electric expreess locomotive is fixed in the pump housing by support.

The utility model additionally provides a kind of new multistage vacuum pump, and it has above-mentioned arbitrary described vacuum pump tandem compound to form.
Vacuum pump of the present utility model and new multistage vacuum pump structure simply compact, volume is little, and do not need other match equipment, limiting vacuum is higher, and consumed power is lower, and noise is little.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of vacuum pump of the present utility model, comprise the straight tube shape pump housing 2, the two ends of the pump housing are provided with adpting flange, fastening by screw rod between adpting flange.The two ends of the pump housing 2 are respectively equipped with suction port and air outlet, two ends in the pump housing 2 are equipped with a clockwise high-speed electric expreess locomotive 1 and a reverse high-speed electric expreess locomotive 3 respectively, high-speed electric expreess locomotive is fixed in the pump housing by support, the rotating shaft of two high-speed electric expreess locomotives is relative, sense of rotation is contrary, the rotating shaft of two high-speed electric expreess locomotives is respectively provided with 3 impellers 4, the quantity of impeller can need to adjust according to the difference of pressure size.Between adjacent fan-wheel 4, be provided with stator 5, pump housing center is provided with the support 6 for supporting rotation shaft of high-speed motor.The sense of rotation of two high-speed electric expreess locomotives is contrary, and clockwise high-speed electric expreess locomotive 1 drives impeller high speed rotating in rotating shaft to bleed, and reverses high-speed electric expreess locomotive 3 impeller and pins air-flow and be vented.
For cooling in time in the situation of working long hours to above-mentioned vacuum pump, also comprise a cold-water tank, one end of cold-water tank connects intake pipe, and the other end is connected to the suction port end of the pump housing by pipeline, and joint is provided with shell fragment.Pump housing wall is provided with temperature transducer, and temperature signal is sent to temperature controlling instrument by temperature transducer, and control signal is sent to relay by temperature controlling instrument, the opening and closing of Control cold-water tank pipeline.When temperature exceedes predetermined value in the pump that temperature transducer measures, can open cold-water tank pipeline by temperature controlling instrument and relay, cooling water forms water smoke at the suction port end of the pump housing and lowers the temperature to high-speed electric expreess locomotive and the pump housing, then discharges from air outlet with air-flow.
The utility model additionally provides a kind of new multistage vacuum pump, is formed by multiple above-described vacuum pump tandem compound.
Vacuum pump of the present utility model and new multistage vacuum pump structure simply compact, limiting vacuum is higher, and consumed power is lower, and noise is little.
Personnel in the art should be realized that; above-described embodiment is not used as restriction of the present utility model; as long as in spirit of the present utility model, any protection domain of the present utility model is not all exceeded to above-described embodiment technique variation, deformation program.
