Problems solved by technology
[0003] Most of the vacuum pumps on the existing market are used in conjunction with the motor, and can work normally only under the drive of the motor. Therefore, the use of this type of vacuum pump is subject to certain restrictions, especially in some emergency rescue sites. Uncertainty is difficult to use when there is no power supply, which affects the timeliness of rescue. At the same time, many vacuum pumps use oil medium to extract air. When the vacuum pump equipped with a motor leaks electricity, it is easy to cause a fire. cause immeasurable loss

Embodiment Construction
[0019] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0020] Such as figure 1 , figure 2 As shown, the new rotary vane vacuum pump includes a pump body 1 and a front end cover 2 and a rear end cover 3 arranged at both ends of the pump body 1. The pump body 1 has a hollow pump chamber 4, and the pump chamber 4 is provided with an eccentrically installed The rotor 5, one end of the rotor 5 extends outside the front end cover 2, and is used to connect with the shaft of an external engine. This new type of rotary vane 8-type vacuum pump is currently widely used in emergency rescue vehicles for vacuum assistance, and is powered by the diesel engine of the vehicle to make the pipeline Negative pressure is rapidly generated inside, so that the pumped water can quickly enter the wa...

The invention provides a novel rotary vane vacuum pump, and belongs to the technical field of mechanical manufacturing. The novel rotary vane vacuum pump solves the problems that potential safety hazards exist in the existing vacuum pump driven through a motor, and the use environment is limited. The novel rotary vane vacuum pump comprises a pump body, a front end cover and a rear end cover, wherein the front end cover and the rear end cover are arranged at the two ends of the pump body; the pump body is provided with a hollow pump cavity, a rotor eccentrically installed is arranged in the pump cavity, rotator grooves are formed in the rotor, and each rotor groove is internally provided with a rotary piece; the top of the pump body is provided with an air inlet port communicated with the pump cavity, the side portion of the pump body is connected with an oil tank, and a fixing frame is connected between the oil tank and the pump body; an oil return pipe is arranged at the front end ofthe oil tank, an front oil inlet pipe and a rear oil inlet pipe are arranged on the side wall of the oil tank, a cooling pipeline is arranged at the tail end of the rear oil inlet pipe, and the cooling pipeline is connected with the pump cavity through the rear end cover; and an exhaust filter and an oil filter are arranged in the oil tank, and an air outlet port is formed in the position, corresponding to the exhaust filter, of the oil tank. The novel rotary vane vacuum pump has the advantages of being safe, reliable and wide in application occasion.
Description
technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and relates to a vacuum pump, in particular to a novel rotary vane vacuum pump. Background technique [0002] Vacuum pump is a rotary variable volume gas delivery pump, which has the characteristics of high pumping speed in a wide pressure range and is widely used in metallurgy, chemical industry, food, electronic coating and other industries. Rotary vane vacuum pump is a kind of vacuum pump. Its main function is to continuously inhale and discharge gas to achieve the purpose of pumping air. Its working principle is: the rotor is installed in the pump casing with a certain eccentricity and connected The fixed surface of the pump is close to the fixed surface, and two (or more than two) rotary vanes are installed in the rotor slot. When the rotor rotates, the rotary vanes can slide back and forth along the radial groove and always contact the inner wall of the pump casing. The rot...
