Problems solved by technology
[0002] The existing vortex air pump is usually connected by two shells, and a chamber is formed inside the shell after the connection is completed, but because the two shells are metal shells, after the connection is completed, the sealing performance between the metals Poor, it is difficult to completely seal the gas, so the efficiency of the air pump to compress the gas is low; at the same time, the vortex air pump needs to compress the gas, and the gas pressure after compression is strong, so it is easier to connect the two shells Leaked out, and because the gas leakage is usually a small amount, it is difficult to find the gas leakage

The invention discloses a swirl type gas pump with a high mechanical seal structure. The swirl type gas pump with the high mechanical seal structure comprises a shell, impellers arranged in the shell,and a drive piece for driving the impellers to rotate. The shell comprises a first shell body and a second shell body matched with the first shell body; and a liquid seal part is arranged at a connected part of the first shell body and the second shell body. According to the swirl type gas pump with the high mechanical seal structure provided by the invention, the liquid seal part is arranged forenabling a gap of the shell to achieve liquid-sealing, so that the safety is high, a sealing effect is good, a gas cannot be leaked, and the gas compression efficiency of a pump body is high; and through the liquid seal part, the gas leakage, a gas leakage position and the gas leakage amount can be conveniently found directly, so that the sealability of the connected part of the first shell bodyand the second shell body is adjusted conveniently.
Description
technical field [0001] The invention belongs to the technical field of vortex air pumps, in particular to a vortex air pump with high mechanical seal structure. Background technique [0002] The existing vortex air pump is usually connected by two shells, and a chamber is formed inside the shell after the connection is completed, but because the two shells are metal shells, after the connection is completed, the sealing performance between the metals Poor, it is difficult to completely seal the gas, so the efficiency of the air pump to compress the gas is low; at the same time, the vortex air pump needs to compress the gas, and the gas pressure after compression is strong, so it is easier to connect the two shells Leak out from the place, and because the gas leakage is usually a small amount, it is difficult to find the gas leakage. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a vortex air pump w...
