Selection of swimming pool water treatment equipment


We know that a series of water treatment systems will use swimming pool water treatment equipment. Therefore, choosing a suitable swimming pool water filter model for the swimming pool is an important aspect to improve the filtration efficiency of water treatment. 1. Hair filter a. The finished hair filter should be used first, but detailed information should be requested to check whether the total area of ​​the filter cartridge (mesh) hole (mesh) meets the specification requirements.

b. The shell should be made of corrosion-resistant materials, such as glass fiber reinforced plastics, stainless steel or copper. If cast iron or carbon steel is used, anti-corrosion treatment should be carried out, and anti-corrosion coatings or lining anti-corrosion materials that meet hygienic requirements should be painted. The working pressure of the shell should not be less than 0.35MPa. c. The hair filter (tube) is generally made of copper, stainless steel, or high-density plastic.

d. Hair filtration requires daily cleaning of the net (tube), so the structure of the shell should be simple, flexible in loading and unloading, and good in sealing performance. e. The total area of ​​the holes (mesh) of the filter cartridge (net) should not be less than 2.0 times the cross-sectional area of ​​the connecting pipe. The hole diameter of the filter cartridge should be 3-4mm, and the filter mesh should be 10-15 mesh.

2. Circulating water pump a. The number of circulating water pumps should be configured according to the simultaneous operation of multiple pumps to reduce the capacity of the standby pump. b. The circulating water pump should be a swimming pool special pump made of integral copper, stainless steel or high-density, high-strength plastic with a large-volume front-end swimming pool water filter. c. If a cast iron circulating water pump is selected, the impeller should be made of copper or stainless steel, the mechanical seal should be made of corrosion-resistant materials, and the motor should be fully enclosed.

d. When conditions permit, it is advisable to use a low-speed swimming pool water circulation pump to facilitate flow adjustment and reduce noise. e. Measures for vibration reduction and noise reduction should be provided for water pumps and pipelines. f. The flow velocity of the water pump suction pipe should be 1.0-1.5m/s, and the flow velocity of the water pump outlet pipe should be 1.5-2.5m/s.
