swimmingPool equipment

I. Product Features:

　　Yuanlai filter sand tank is made by winding and bonding high-strength resin and glass fiber. High strength, resistant to aging and strong corrosion. It is particularly suitable for seawater, chemical industry, swimming pools, landscape poolsSPAWater treatment circulation filtration for spa pools, etc. The overall equipment of the sand filter tank is lightweight, and the filter material uses ordinary quartz sand, which is low-cost. If the entire sand filter tank uses biochemical materials as filter media, it can also function as a biochemical filter. The interior of the sand filter tank adopts a water distributor structure, making backwashing operation simple and convenient. It is a very commonly used device in modern aquarium engineering, swimming pool engineering, aquaculture engineering, sauna engineering and other water treatment industries.

Ii.Working principle

　　The filter sand tank uses special filter sand to remove the tiny impurities in the pool. Filter sand, as the medium for cleaning dirt, is filled in the cavity of the filter sand tank. When the control knob is turned to"FILTER"When in position, the pool water containing suspended dirt particles is pumped into the filter pipeline and then guided by the control switch to the outlet of the filter. The pool water passes through a filter, and tiny impurities are captured and filtered out by the sand bed. The filtered clear water flows from the bottom of the filter through the control switch and then back to the swimming pool via the pipeline. This entire set of procedures is continuous and automatic, and provides a complete circulation process for the swimming pool filter and piping system. After a period of use, the accumulated dirt in the filter hinders the water flow and weakens it. At this point, the filter needs to be cleaned. Turn the control switch to"BACKWASH"At this point, the water flow changes to the opposite direction, directly reaching the bottom of the filter chamber, and then backwashes up through the sand layer, lifting the previously collected dirt and residue and discharging them from the sewage outlet. After each backwash, the control switch should be set to"RINSE"Location: Start the water pump0.51Turn it off in minutes and then hit"FILTER"Position, and restart the normal filtering."

Hair filter

I. SetBrief Introduction

　　Hair filters are used to filter sewage or circulating water containing hair, fibrous substances and fine fabrics and other impurities. It is also called a vertical straight-through dirt separator or a blue filter. It is commonly used in swimming pools as a circulating water filtration device for swimming pools.

Ii.Main control parameters

　　The materials of the hair filter tank include carbon steel, stainless steel andU-PVCThe net basket is made of stainless steel

Iii.Technical performance requirements

　　1The top cover of the hair filter is equipped with an exhaust valve, and an observation hole is provided on the tank body.

　　2The design pressure is not less than the working pressure1.5The test pressure shall not be less than the design pressure1.5Double.

　　3The sum of the areas of the holes is greater than the cross-sectional area of the connected pipes2.0The diameter of the filter cylinder holes is adopted3～4mm,The filter mesh adopts10～15"Eye.

　　4The structure of the hair filter is simple and reliable, with flexible installation and removal, easy disassembly and cleaning, and good sealing performance.

　　5The inlet and outlet dimensions of the hair filter are the same.

FourKey points for product selection

　　1It should be installed on the suction pipe of the circulating water pump and strictly in the direction of the water flow of the hair filter. Reverse installation is not allowed.

　　2Hair filters should be installed on the foundation or the ground and must not rely on pipes to bear their weight.

　　3After installation is completed, it should be tested for tightness and pressure resistance together with the suction pipe
