Embodiment Construction
[0009] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0010] exist figure 1 Among them, the sealing piece 3 is installed in the left sealing body 1 and the right sealing body 2, and the nitrogen punching hole 6, the pressure equalizing ring filling groove 4 and the wool felt filling groove 5 are installed in the left sealing body 1.
[0011] The pressure equalizing ring is used to fill the groove 4 in front of the inflatable ring, and the two sealing teeth at the back are additionally equipped with wool felt to fill the groove. There is a good sealing effect in the case of not allowing air, and the addition of a nitrogen pressurization system can completely solve the oil mist leakage phenomenon.

The invention relates to the field of oxygen-enriched air blowers, and provides an oil tank sealing device of an oxygen-enriched air blower. The oil tank sealing device of the oxygen-enriched air blower is characterized in that sealing plates are respectively arranged in a left sealing body and a right sealing body; and a nitrogen charging hole, a pressure equalizing ring filling groove and a wool felt filling groove are formed in the left sealing body. By using the technical scheme, pressure equalizing gas ring nitrogen charging is performed on an oil seal, so that the oil seal and a spindle have a pressure equalizing phenomenon in a running process of the air blower, and the problem that oil mist is sucked by the oxygen-enriched air blower in a negative-pressure manner, and explosion is caused can be solved.
Description
technical field [0001] The invention relates to the field of an oxygen-enriched blower, and relates to an oil tank sealing device for an oxygen-enriched blower. Background technique [0002] At present, the palace seal used in the oxygen-enriched blower is one of the most critical and important wearing parts in the blower. It can control lubrication leakage and oil mist leakage parts caused by high temperature. If the design is not sufficient, it will lead to "three leakages" such as oil leakage, air leakage, and oil mist leakage caused by poor sealing of the blower, resulting in blower oil leakage. Mixes with enriched oxygen to produce an explosion. [0003] The "three leaks" of the blower are very harmful: first, it will cause an explosion, and the consequences will be unimaginable; second, it will increase the consumption of oil, waste energy and increase the cost; The service life of the blower will increase the repair cost; the fourth is to affect the appearance and ...
