Installation site drawing of tubular aerato

  1、 [product introduction] tubular rubber aerator is a new type of tubular rubber aerator developed by our company
This product is mainly used for oxygenation of urban sewage and organic industrial wastewater treatment system
It has the advantages of simple structure, high oxygen utilization rate, reliable performance, not easy to block pores, no backflow of sewage, uniform circumferential stress, long service life, convenient installation and maintenance The system has the characteristics of low price and so on
This product has been imported for a long time
Our company has conducted in-depth research on it to make its performance reach the international level of similar products, which can be Save a lot of foreign exchange and promote China's research in the field of microporous aerator

[product structure]
u  The rubber membrane tube adopts silica gel and ethylene propylene diene monomer (EPDM), which has the characteristics of heat resistance, ozone resistance, acid and alkali resistance and good chemical stability
Compared with the general rubber membrane, it can greatly improve its service life

u  The aeration hole is a zigzag long hole, which makes it have good expansibility and instantaneous closure
During aeration, micro bubbles with a diameter of less than 3mm can be released to obtain high oxygen utilization rate, which is 25 ~ 35%

u  The support body is hollow and filled with water, which greatly reduces the buoyancy of the aerator in the water

u  The air guide groove is adopted to make the air distribution inside the aerator rapid and uniform, so as to make the stress of the aeration membrane pipe uniform, prolong the service life of the aeration membrane pipe and the uniformity of releasing bubbles, and improve the aeration effect; The air guide groove is a narrow groove, and the rubber film pipe area on it does not open an air vent
When the air supply is stopped, the rubber film clings to the air guide groove, so as to prevent the backflow of sewage

[ordering instructions]
u  Please specify the specification, model and quantity of aerator when ordering

 
2、 The tubular aerator is mainly used for oxygenation of urban sewage and organic industrial wastewater treatment system
The tubular aerator has the characteristics of simple structure, high oxygen utilization rate, reliable performance, difficult blockage of pores, no backflow of sewage, uniform circumferential stress, long service life, convenient installation and maintenance, low system price and so on
Description of accessories: 1 plug, 2 stainless steel clamp, 3 aerator body, 4 aerator micropore, 5 connector, 6 gasket I, 7 gasket II, 8 center pipe, 9 distribution pipe and 10 bending plate

Structure:
Aeration diaphragm, support pipe and air pipe
The outer diameter of the tubular aerator is 69mm, generally 580mm, 800mm and 1000mm
Extrusion or molding is adopted when the length is below 580mm, and extrusion is adopted when the length is greater than 580mm
1
5mm on the membrane tube, 2 & times; 2
5mm spacing drilling can produce uniform micro bubbles with a diameter of 1-3mm
There is a 15mm long non porous area on the top of the membrane tube
When the air supply is cut off, the membrane will be restored to its original state immediately
It can automatically prevent countercurrent at the air inlet

texture of material:
1
The rubber diaphragm adopts EPDM, which has the characteristics of heat resistance, ozone resistance, acid and alkali resistance and good chemical stability
Compared with the general rubber film, it can greatly improve its service life

2
The aeration hole is a zigzag long hole, which makes it have good expansibility and instantaneous closure
During aeration, micro bubbles with a diameter of less than 3mm can be released to obtain high oxygen utilization rate, which is 35 ~ 42%

3
The support pipe is made of ABS or PVC

4
The air pipe is made of engineering plastic ABS and is hollow and filled with water, which greatly reduces the buoyancy of the aeration system in the water

 
3、 Precautions for storage of tubular aerator
1
According to DIN 7716 or ISO 2230, the aerator and all accessories in the original package should be stored in a dry and ventilated room

  2
Prevent freezing, overheating, direct sunlight, dust, mineral oil and hydrocarbon pollution

  3
Store away from the engine, especially not close to the blower

  4
Avoid any damage to the aerator and its packaging

  5
Do not store outdoors! The storage time on site (from to installation / operation) shall not exceed 1 year
Otherwise, we should consult Yager's preventive measures

  6
When stored on site, all aerators and accessories must be stored in the original packaging
When exposed to the sun, the large cardboard box shall be coated with oily waterproof cloth to prevent ultraviolet radiation

  7
Packaging materials containing plasticizer shall not be used

4、 Function of tubular aerator
When working under air pressure, the tubular aerator automatically opens and enters the pool
If the oxygen in the air disappears and the pressure disappears, the microporous aeration pipe will be closed automatically to prevent water from invading the micropores
In the process of sewage treatment, it can be used or stopped for a long time, and then put into use
It will not be blocked and recycled in the micropores
  The channel greatly reduces the resistance loss of the tubular aerator; Variable automatic opening and closing of holes and cracks to completely solve the aeration hose; Linear aeration, gas distribution and the formation of vertical circulation, more uniform mixing; Small bubble aeration hose, high oxygen utilization rate and different efficiency of dynamic aerator
The design mode can be used to adjust the working pressure
Different distance and density can change the aeration efficiency
