The traditional aerator rubber diaphragm is replaced with a rubber diaphragm with extension compensation, which can rebound freely, avoiding the tearing and falling off of the diaphragm due to stress concentration. The reverse buckle folding structure with good sealing performance is adopted between the diaphragm and the support plate, which greatly prolongs the service life and effectively avoids the phenomenon of diaphragm falling off.
The diaphragm adopts an internal check valve design - a thickened center without holes. When the air supply is turned off, under the action of water pressure and the elasticity of the diaphragm itself, the center of the diaphragm falls back on the hole of the support plate, and the unperforated area just covers the air release hole, just like a check valve to prevent liquid from flowing back into the aeration system.
The diaphragm is made of imported ethylene propylene diene rubber (EPDM), which is anti-aging, corrosion-resistant,acid and alkali resistant, and durable.
The diaphragm type aerator is made of ABS engineering plastic as the main body and is processed through a special process. When the microporous aerator is oxygenated and aerated, the incoming air passes through the buffer and is directly sent to theaerator to ensure that the rubber diaphragm has low resistance at one time.
The diaphragm diffuser uses ABS engineering plastic as the chassis and support plate. The air distribution membrane is made of ethylene propylene diene monomer (EPDM) or silica gel material. The aeration device consists of an aerator, regulator, connectors and air distribution pipes.
1.Small bubble diameter
2.Bubblediffusion uniformity
3.Strong corrosion resistance
The tubular microporous aerator is a mature, reliable, energy-saving and efficient aerator, mainly used in the field of municipal sewage and industrial sewage. It has the characteristics of small pressure loss, high oxygen utilization rate, uniform bubble diffusion, strong corrosion resistance, low energy consumption, high efficiency and long service life.
01.The rubber membrane tube is made of silicone and EPDM, which has the characteristics of heat resistance, ozone resistance, acid and alkali resistance, and good chemical stability. Compared with general rubber membranes, its service life can be greatly improved.
02.The support body is hollow and filled with water, which greatly reduces the buoyancy of the aerator in water.
03.The aeration holes are long straight holes, which have good expandability and instantaneous closure. During aeration, micro bubbles with a diameter of less than 2MM can be released to obtain a higher oxygen utilization rate, which is 28 to 35%.
04.The air guide groove is used to distribute the air inside the aerator quickly and evenly, so that the aeration membrane tube is evenly stressed, which prolongs the life of the aeration membrane tube and the uniformity of bubble release, and improves the aeration effect; the air guide groove is a narrow groove, and the rubber membrane tube area on it has no aeration holes. When the air supply is stopped, the rubber membrane clings to the air guide groove, thereby preventing the occurrence of sewage backflow.
The liftable aerator adopts advanced anti-buoyancy technology and is suspended for installation. It can be installed and maintained without affecting normal operation (without stopping water supply or air supply). The liftable device can directly lift the aerator out of the water for thorough cleaning and maintenance, so that the aeration system is in a brand new state, thereby reducing fan loss, maintaining high power efficiency, and reducing operating costs.
