Answer: (1) For the production water of the compressed air station, except for those where interruption of the compressed air supply will cause great losses, it is advisable to use a one-way water supply.
(2) For the cooling water of the compressed air station, except for the local water resources are abundant and the direct current water supply system is allowed, a circulating water or reused water system should be used. The circulating water should adopt an open high-level cooling tower or a closed system.
(3) When the temperature difference between the inlet and outlet water of the air compressor is less than 10℃ or a closed circulation system is used, the water pressure can be appropriately greater than 0.07MPa.
(4) A drainage funnel or water flow observation device must be installed on the drainage pipe of the air compressor unit.
(5) The water supply and drainage system of the compressed air station should ensure that the stored water can be drained.
