Sand cylinder of swimming pool equipment: working principle, characteristics and types


The filter is to use special filter sand to eliminate the tiny dirt in the pool. Filter sand is used as a medium for removing dirt and is packed in the cavity of the filter. When the control knob is turned to the "filter" position, the pool water containing suspended dirt particles is pumped into the filter pipeline, and then guided by the control switch to the water outlet of the filter.

The pool water passes through the filter, and the microscopic dirt is captured and filtered out by the sand bed. The filtered clean water passes through the control switch at the bottom of the filter and returns to the swimming pool through the pipeline. This entire process is continuous and automatic and provides a complete cycle for the pool filter and plumbing system.

After the filter has been used for a period of time, the accumulated dirt will hinder the water flow and weaken it. At this time, the filter must be cleaned. For example, for the filter sand tank of Guangdong Boying Environmental Protection Equipment Co., Ltd., when the control switch is turned to the "backwash" position, the water flow becomes the reverse direction, and the water flow directly reaches the bottom of the filter cavity, and then passes through the The sand layer recoils up, and the previously collected dirt and residue are washed up and discharged from the sewage outlet. After each backwash, the control switch should be turned to the "flushing" position, and the water pump should be turned on for 0.5 to 1 minute, then turned off, and then turned on. Go to the "Filter" position and start normal filtering again.

1. FILTER (normal filtration) 2. BACKWASH (backwash, discharge the dirt accumulated in the filter) 3. RINSE (after backwash, discharge the dirt in the sewage pipe) 4. WASTE (direct drainage without filter) 5. RECIRCULATE (without filter circulation) 6. CLOSED (close the filter equipment) Scope of application of swimming pool equipment filters: After more than 50 years of use and improvement at home and abroad, the sand filter system can be said to be a mature and perfect system. Swimming water treatment system is mainly suitable for large, medium and small swimming pools, small and medium landscape pools and other domestic water systems. Water filtration for swimming pools, water parks and massage pools Seawater and freshwater aquaculture Industrial water purification Drinking water pretreatment Agricultural irrigation Diatomite filtration system is suitable for household drinking water systems and small and medium-sized private buildings due to its high-precision filtration swimming pool. In recent years, the transformation of this system has been applied to the post-treatment of water quality in waterworks.

Swimming pool equipment filter features: 1. The stainless steel sand tank is permanently indestructible, and the effective service life is at least 50 years. The life of the glass fiber sand tank is 5 years; 2. The stainless steel sand tank is very environmentally friendly and will not cause secondary pollution to the water quality. The glass fiber sand tank will slowly dissolve, causing secondary pollution to the water quality, and the glass fiber dissolved in water will cause serious damage to the human body, and is a strong irritant and a strong carcinogen.

The use of glass fiber sand tanks has been banned in developed countries; 3. Stainless steel sand tanks are very corrosion-resistant and are the necessary filter equipment for mariculture and aquariums, while glass fiber sand tanks cannot be used for this purpose; 4. The effectiveness of stainless steel sand tanks The temperature resistance can exceed 300 degrees, while the temperature resistance of the glass fiber sand tank is only 43 degrees; therefore, it is the preferred filter equipment for hot springs; 5. The surface of the stainless steel filter sand tank is smooth and the texture is excellent, which can effectively improve the grade of swimming pool equipment; 6. Stainless steel sand tank The cylinder can be customized for any flow rate equipment. Swimming pool equipment filter type: sand tank, side filter sand tank, top filter sand tank, deep filter sand filter, filter unit, horizontal filter sand tank, diatomite fiber filter Poolking is the best swimming pool equipment manufacturer and supplier in China.
