Problems solved by technology
[0003] The present invention mainly provides a method of cooling the vacuum pump oil by using an external condenser, and using the fan on the motor side of the vacuum pump to cool the condenser by air at the same time, the cooling effect of the vacuum pump oil is good, and the service life of the vacuum pump oil is prolonged. It is conducive to the stable performance of the vacuum pump performance, and the external oil cooling structure of the energy-saving and environmentally friendly rotary vane vacuum pump solves the problem that the oil in the rotary vane vacuum pump cannot be effectively cooled when the oil temperature is high in the prior art, resulting in accelerated oxidation and deterioration of the vacuum pump oil. The service life is reduced, and in severe cases, it directly affects the performance of the vacuum pump and other technical problems

The invention discloses an external oil cooling structure of a rotary-vane vacuum pump; and the energy-saving and environment friendly external oil cooling structure of the rotary-vane vacuum pump, which is used for cooling vacuum pump oil by using an external condenser, used for air-cooling the condenser by using a motor fan, has a good vacuum pump oil cooling effect, is used for prolonging the service life of the vacuum pump oil and is beneficial for stably developing the performance of the vacuum pump, is provided; technical problems that oxidative deterioration of the vacuum pump oil is accelerated because the rotary-vane vacuum pump oil at high temperature cannot be effectively cooled, the performance of the vacuum pump is directly affected when serious oxidative deterioration is caused and so on are solved; the condenser is arranged on the other side of the vacuum pump of the motor fan; an inlet end of the condenser is connected with one end of a condenser oil inlet; an outlet end of the condenser is connected with one end of a condenser oil outlet pipe; the other end of the condenser oil inlet pipe extends and is communicated with a corresponding lubricating passage above a pump stator; and the other end of the condenser oil outlet pipe extends and is communicated with an oil tank.
Description
technical field [0001] The invention relates to a rotary vane vacuum pump, in particular to an external oil cooling structure of the rotary vane vacuum pump which is environmentally friendly, energy-saving and has a good oil cooling effect of the vacuum pump. Background technique [0002] Vacuum pump is a device that generates, improves and maintains vacuum in a closed space by means of mechanical, physical, chemical or physical chemistry. It is widely used in the fields of medicine, chemical industry, electronic technology, vacuum drying, refrigeration, etc. Among them, the rotary vane vacuum pump is the most widely used as the primary pump, but the rotary vane vacuum pump has the following problems, especially when it is used in the electric light source industry, that is, the oil content of the vacuum pump The oil temperature will gradually increase after operation, especially when the ambient temperature is high. Due to the high temperature of the working environment of ...
