12 inch Crown Type Disc Diffuser Aerator with EPDM Membrane In Black
Product Description
1. Aerator diaphragm: EPDM rubber (100% imported from Bayer company of Germany, Shanghai Sanpu sales company) shall be used. The surface of rubber diaphragm shall be smooth, flat, free of impurities, bubbles and cracks. The raw materials are mainly imported high-quality synthetic rubber with special ingredients, which are made by injection molding machine through scientific formula. It has the advantages of strong corrosion resistance, high strength and temperature resistance, and its service life can be more than 5-6 years. The materials meet the national urban construction industry standard CJ / t3015.4-1996.
2. The aerator base, screw gland, guide rib, air distribution pipe, connecting flange, elbow, blowdown device, fixed main pipe regulating bracket, etc. are all made of ABS engineering plastic; cast plastic molding has the characteristics of high strength, high pressure bearing, good impact resistance, use temperature of - 30 ~ + 100 ℃, UV radiation resistance, acid, alkali and chemical corrosion resistance.

The aeration device is composed of rubber membrane microporous aerator, gas distribution pipeline, regulator, connector, clearing device, etc. The gas distribution pipeline is arranged in a circular way. The rubber membrane microporous aerator is connected with G3 / 4 thread according to the gas supply volume and pool shape. The rubber membrane microporous aerator at the base (fixed on the gas distribution pipeline) is external thread. When installing, fix the regulator at the bottom of the pool according to the required size expansion accumulation bolt, and then fix the gas distribution pipeline on the regulator. In order to prevent other actions For example, when welding sparks and civil engineering, concrete and other heavy objects damage the aerator, it must be placed on the aerator before discharging water after civil engineering. In order to prevent the air leakage of the pipeline and the connecting part, the water shall be drained more than 10 cm of the aerator for leakage test. The air leakage of the connecting part of the ventilation pipeline shall be eliminated in time and then put into operation formally.
Debugging Mothed
Commissioning inspection method after the installation of aerator, put clear water into the tank, and the water surface to the surface of aerator is about 100-200mm. Then carry out the following three checks. In the process of water drainage and observation, observe whether the elevation of the aerator is on a horizontal plane, and adjust it (the bottom surface of the pool shall be level during the civil work, and the discharge outlet shall be reserved). Check whether there is air leakage in sealing treatment of all pipeline interfaces. Under the condition of standard ventilation capacity of 2m3 / h, check whether the air distribution of the aerator is uniform, and the ventilation area of each aerator shall be greater than 80%.
