The invention discloses antibacterial coating equipment for a flexible base material and a method thereof, and relates to the technical field of coating equipment. The antibacterial coating equipment for the flexible base material comprises a base and a coating box body arranged on the base, vacuum equipment is arranged on the base and connected with the coating box body through a vacuum pipe, a sputter coating head is arranged in the coating box body, a rotating wheel is rotationally connected in the coating box body, and a positioning ring plate is movably clamped in the rotating wheel. According to the antibacterial coating equipment for the flexible base material, through the design of the rotating wheel and the positioning ring plate, base material main bodies of various models and sizes can be conveniently fixed, the fixed base material main bodies are not prone to wrinkling, self-rotating coating of the base material main bodies is achieved in cooperation with the design of the rotating wheel and the driving mechanism, on one hand, it is guaranteed that the whole equipment is compact in structure, and on the other hand, the structure is compact; and on the other hand, the film coating effect on the base material main body is good, and the film coating is uniform.

This utility model discloses an improved direct-connection pump house, including a pump house body. Two sets of water pumps are installed within the pump house body. One end of each set of water pumps is connected to a flanged butterfly valve (fourth type). One end of the flanged butterfly valve (fourth type) is connected to a connecting pipe. The free end of the connecting pipe is connected to a water pipe (first type). The right end of the water pipe (first type) is connected to a Y-type filter. The right end of the Y-type filter is connected to a flanged butterfly valve (first type). The right end of the flanged butterfly valve (first type) is connected to a sanitary pipe (first type). The other ends of the two sets of water pumps are connected to a connecting elbow. A check valve is connected to the top of the connecting elbow. This utility model, through a dual-pump parallel architecture, switches between pumps in case of a single pump failure, ensuring continuous water supply. Independent control is achieved through the connecting pipe and the flanged butterfly valve (fourth type).
