Abstract
Description
Technical Field
[0001] The utility model relates to an oil rotary vacuum pump heat dissipation device. Background Art
[0002] In the existing oil rotary vacuum pump technology, the pump body is the main structure of the entire pump, which contains rotating vanes and oil circuits. The rotation of the main motor drives the vanes to rotate rapidly. Due to the centrifugal force inside the pump body, the vanes will suck the gas from the air inlet into the pump chamber. At the same time, the lubricating oil will be sucked into the pump chamber under the negative pressure of the vanes to form a sealed space to prevent gas leakage. It also has the function of lubricating the vanes to prevent wear of the high-speed rotating vanes. As the vanes continue to rotate, the gas inside the pump chamber is gradually compressed, and the lubricating oil forms an oil seal that will move continuously, pushing the gas out, and the lubricating oil is pushed back into the oil tank.
[0003] Since there are many types of vacuum pumps available, which are roughly divided into dry vacuum pumps, Roots vacuum pumps, water ring vacuum pumps, oil rotary vacuum pumps, etc., most capsule filling equipment used in the pharmaceutical manufacturing industry chooses oil rotary vacuum pumps. Because of the same volume and power, the vacuum pumping speed generated by the oil rotary vacuum pump is large and the vacuum duration is long, but the following problems will arise: Problem 1: The optimal working temperature of the vacuum pump lubricating oil is between 50-70 degrees. Due to the friction between the motor rotation and the rotor inside the pump chamber during long-term production, the lubricating oil becomes ultra-high temperature and viscous, the oil-gas separator cannot separate, and the rotor cannot be effectively lubricated. Problem 2: Because it is used for drug filling, the drug is sucked into the pump chamber from the fine powder particles, and the equipment generates high temperature during continuous operation. The lubricating oil cannot play the role of cooling the equipment, causing the lubricating oil to evaporate, and the oil-gas separator cannot effectively separate, resulting in odor. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide an oil rotary vacuum pump heat dissipation device, which is used to solve the problem that the friction between the motor rotation and the rotor inside the pump chamber for a long time causes the lubricating oil to become ultra-high temperature and viscous, the oil and gas separator cannot separate, and the rotor cannot be effectively lubricated.
[0005] In order to solve the above problems, the technical solution of the utility model is:
[0006] The invention discloses an oil rotary vacuum pump heat dissipation device, comprising a vacuum pump. The bottom of the vacuum pump body is connected with a circulation pump, a radiator and the top of the vacuum pump body in sequence through a pipeline, and a heat dissipation fan is arranged on one side of the radiator.
[0007] It also includes a temperature controller, a temperature controller probe is connected to the vacuum pump, and the radiator and the circulation pump are electrically connected to the temperature controller.
[0008] Also included is a trailer on which the vacuum pump, radiator, circulation pump and thermostat are mounted.
[0009] An air filter and an oil-gas separator are respectively connected to the air inlet and the exhaust port of the vacuum pump.
[0010] The beneficial effects of the utility model are as follows: a radiator and a circulating pump are added to the existing vacuum pump, and the radiator is used to cool and dissipate the lubricating oil in the pump body of the vacuum pump, so that the temperature of the lubricating oil is controlled between 50 and 70 degrees, thereby ensuring that the equipment can work stably for a long time, reducing the evaporation of the lubricating oil and preventing the generation of odor.

[0015] like Figure 1 and 2 As shown, an oil rotary vacuum pump heat dissipation device includes a vacuum pump 6, the bottom of the vacuum pump 6 pump body is connected with the circulation pump 3, the radiator 2 and the top of the vacuum pump 6 pump body in sequence through a pipeline, and a heat dissipation fan 8 is provided on one side of the radiator 2. The lubricating oil in the pump body is drawn by the circulation pump 3 and enters the radiator 2 for heat dissipation, and then is returned to the circulation pump 3 to cool and dissipate the lubricating oil.
[0016] The thermostat 4 is also included, the probe of the thermostat 4 is connected to the vacuum pump 6, and the radiator 2 and the circulating pump 3 are electrically connected to the thermostat 4. The thermostat 4 sets the starting temperature of the circulating pump 3 and the fan to about 70 degrees Celsius, and the stopping temperature to 60 degrees Celsius, so as to automatically control the temperature of the lubricating oil in the oil pump to between 50 and 70 degrees, so that the lubricating oil of the vacuum pump 6 is at the best working temperature, thereby extending the service life of the vacuum pump 6.
