Description

HMD 200/270/340 Disc type DIFFUSER

 

HMD series disc aerator is a patented product developed according to years’ project feedback and air diffuser long-term operation condition, optimization of raw material ratio and improvement of product structure.

 

 

Reliable product material:

(1) Rubber membrane: use high-quality rubber raw material, and customize material composition and proportion according to the requirement of aeration condition. Excellent physical and chemical properties effectively prevent the contraction, hardening and aging of the diaphragm and extend the product service life.

 

   

(2) Plastic supporting plate: polypropylene fiber and glass fiber are selected, with additives such as anti-aging. This material combination enables the product to retain sufficient strength while having excellent toughness. In addition, product is durable and performance stable with the ability of anti-oxidation, anti-impact, anti-creep and anti-corrosion.

 

Special design for product structure:

(1) The aerator upper cover is designed with an expansion reinforcement structure along the cover inner end, and a number of bulged strips are equipped on the bottom of expansion end and inner of support plate groove part. After the product is assembled, the membrane is firmly fixed in the groove of the support plate. Meanwhile, the ribbed bars on the upper cover and lower plate firmly lock the membrane and make sure the membrane will not falling off.

(2) six "L" clamping strips are designed on the outside of the aerator cover, which can prevent the aerator from falling off the membrane caused by the creep of the plastic cover due to the long time of bearing the expansion of the diaphragm and the external tension pressure.

(3) Special check structure design. There is a convex check ring around air vent of the supporting plate, and a round bulge on the central inner side of the rubber membrane. When the aeration stops, the membrane firmly covers the check ring under the action of its own rebound and water depth pressure. At the same time, the convex on the membrane is stuck inside of the plate check ring, effectively preventing the backflow of mud water. In addition, the protrusion on the inner side of the diaphragm can guide the air flow to diffuse to surrounding, reduce the damage to the membrane in the long-term high-speed air flow, effectively avoid rupture of the membrane central area caused by overstretch, and extend membrane service life.

(4) Optimized design of air channel structure. Expand air hole area, special chamfer design at turning, greatly reduce resistance loss. At the same time, the optional second check structure is specially designed to match the passageway structure to make the air flow smoothly. Reduce product energy consumption and extend service life.

(5) Strengthen the screw root of aeration to prevent the thread fracture.

Data of oxygen transfer efficiency and headloss are measured under different ventilation, under atmosphere, in 6m depth water, 16.5℃.

 

Connector:

During aeration operation, the aeration system is in a state of continuous high strength vibration. Also, heat expansion and cold shrinkage are common during operation. So it has high quality demand to aeration link parts.
Huanchuan patent link accessories perfectly match with disc aerator, and ensure stable product operation, reliable connection and convenient installation. The first rubber, plastic combination connector, it can be applied to high strength working conditions.

Unique connector advantage:

1. Adopt soft rubber connection, which can play a buffer role under the conditions of aeration vibration and thermal expansion and cold contraction to prevent the loose connection

2. Eliminate the traditional adhesive model for better reliable connection. Thread deep into the air pipe to prevent the connection displacement and rotation.

3. The rubber saddle and the fixed adapter can be combined together to form a plastic and rubber combination link, which integrates the advantages of the two links and ensures the aeration system stable and reliable.

4. The splicing structure at both ends of the fixed adapter can cushion the impact and avoid looseness.

5. The connector has no metal parts, which is suitable for various high-salt conditions and free from corrosion.

6. The connector assembly requires no screw fixation during installation. It makes installation faster and convenient.

HC-Fixed adaptor

huanchuan HC-fixed adapter should be used in conjunction with HC-Rubber saddle to form a combination of rubber and plastics, suitable for HMD340 disc aerator and high strength condition.

 

Installation instructions:
According to different engineering requirements, we provide two installation methods:

 

Method1:

1.Tap the rubber saddle into the vent opening.

2.Screw the fine bubble disc diffuser into the rubber saddle internal thread.

  

Method2:

1.Tap the rubber saddle into the vent opening.
