Problems solved by technology
The use of explosion-proof motors for vacuum pumps has the following disadvantages: 1) Increased production costs; 2) The motor shaft and housing of explosion-proof motors are dynamically sealed. If the motor works for a long time, the gap between the motor shaft and the housing will increase. The sealing effect of the casing will be weakened, and if the refrigerant in the refrigerator leaks at this time, the gas may enter the inside of the casing, which may cause an explosion

The invention provides a vacuum pump explosion-proof structure. The vacuum pump explosion-proof structure comprises a vacuum pump, wherein an air inlet of the vacuum pump and an air outlet of the vacuum pump are formed in the vacuum pump, the vacuum pump is sealed in a shell, an air inlet of the shell and an air outlet of the shell are formed in the shell, the air inlet of the vacuum pump is communicated with the air inlet of the shell through an air inlet pipe, the air outlet of the vacuum pump is communicated with the air outlet of the shell through an air outlet pipe, the air inlet pipe is connected with the air inlet of the vacuum pump and the air inlet of the shell in a sealed mode, and the air outlet pipe is connected with the air outlet of the vacuum pump and the air outlet of the shell in a sealed mode. The vacuum pump explosion-proof structure can have very good explosion-proof effect. Various vacuum pumps can be transformed to have the explosion-proof function with the vacuum pump explosion-proof structure. The vacuum pump explosion-proof structure is easy to obtain, simple in structure, low in transformation cost and very good in promotion prospect.
Description
technical field [0001] The invention relates to a vacuum pump, in particular to a structure enabling the vacuum pump to have an explosion-proof function. Background technique [0002] The vacuum pump is a rotary variable volume gas delivery pump, which is widely used in metallurgy, chemical industry, food, electronic coating and other industries. Better preservation effect. The so-called vacuum preservation is to use vacuum to quickly form a low-oxygen and low-bacteria food storage environment, and quickly remove the volatile ripening gas inside the fruit and vegetable tissues and storage environment, which can greatly delay the ripening and aging process of fruits and vegetables , prolong the storage period, and vacuuming can also greatly reduce the base of germs, and exclude most of the microorganisms that may cause rot and deterioration in the storage environment, which greatly delays the decay process of fruits and vegetables. It can be seen that vacuum pumps have also...
