AIR DUCT MACHINES

 Air duct machine is the abbreviation of hidden air conditioner, which can also be called air conditioner air duct machine or air duct machine air conditioner. The indoor unit of the air-conditioning duct machine is the same as one end (fan coil unit) of the central air-conditioning, and both adopt the form of suspended ceiling. There is no difference between them in appearance. Compared with the central air conditioner, the air duct machine air conditioner is cheap in cost and convenient to maintain, and is suitable for people's air conditioner usage habits.

 

Considering aesthetic and economic factors, air duct machines are also widely used in household central air conditioning systems. At present, an indoor unit and the corresponding outdoor unit are widely used as an independent system of air duct machines. This machine solves the problems of hanging up and bare cabinet machines affecting beauty. At the same time, the length of running pipes is longer than that of ordinary household air conditioners, and the installation is relatively flexible. Customers can choose to install one or more of them according to actual needs.

 

The air conditioner is connected with an air pipe to supply air to the room. The so-called high static pressure air pipe machine means that the blower used by the air pipe air conditioner is a high static pressure fan. The static pressure of the air conditioner is equivalent to the residual pressure outside the machine, which is a parameter of the air supply capacity of the air conditioner. The greater the static pressure, the longer the air supply lift. Because the air supply of the air duct type air conditioner needs to pass through the air duct, the loss of air pressure would be increased in the air supply process. If the high static pressure fan is not used, the wind sent to the room would be very little.

 

 

Advantages: Compared with the central air conditioner, the air duct machine air conditioner has lower cost, with the exactly same indoor decoration effect as that of the central air conditioner. Besides, the maintenance is convenient, which is more suitable for the air conditioner usage habits of the Chinese people.

DUCT FLANGE

 Puct flanges are divided into the following six basic types according to the connection mode with the pipe: flat welded flanges, butt welded flanges, socket welded flanges, loose sleeve flanges, threaded flanges and integral flanges.

 

 

Brief Introduction of Pipeline Flange

Flange welding: It is mostly used in the case of relatively mild medium conditions, such as low-pressure non-purified compressed air and low-pressure circulating water. Its advantage is that the price is relatively low.

 

Butt-welded flange: It is the most commonly used one, which is butt-welded with the pipe. The quality of the welded joint is relatively good, and the neck of the flange uses taper transition, which can withstand more severe conditions.

 

Socket welding flange: commonly used in pipelines with PN ≤ 10. 0MPa and DN ≤ 40.

 

Loose flange: It is commonly used when the medium temperature and pressure are not high and the medium is corrosive. When the medium is highly corrosive, the part of the flange contacting the medium (flanging nipple) is made of corrosion-resistant high-grade materials such as stainless steel and other materials, while the outside is clamped by flange rings of low-grade materials such as carbon steel materials to realize sealing.

 

Integral flange: Flange is often integrated with equipment, pipes, pipe fittings, valves, etc. This type is commonly used in equipment and valves.

 

Production Process Flow

The forging process of duct flange machine consists of the following processes: selecting high-quality billet for blanking, heating, forming and cooling after forging. The forging process includes free forging, die forging and fetal membrane forging. During production, different forging methods are selected according to the quality of forgings and the number of production batches.

 

Free forging has low productivity and large processing allowance, but the tools are simple and versatile, so it is widely used to forge single-piece and small-batch forgings with relatively simple shapes. Free forging equipment includes air hammer, steam-air hammer and hydraulic press, which are suitable for the production of small, medium and large forgings respectively.

 

Die forging has high productivity, simple operation and easy realization of mechanization and automation. Die forgings have high dimensional accuracy, small machining allowance and more reasonable fiber structure distribution, which can further improve the service life of parts.

 

Die forging is all called model forging, and the heated blank is forged in a forging die fixed on the die forging equipment.

 

On the middle plate, the disk with the inner and outer diameters and thickness of the flange with processing capacity is directly cut out, and then the bolt holes and waterlines are processed. The flange thus produced is called cut flange, and the maximum diameter of such flange is limited to the width of the middle plate.

 

The process of cutting strips with the middle plate and then rolling them into circles is called rolling, which is mostly used in the production of some large flanges. After successful rolling, welding is carried out, then flattening is carried out, and finally processing of waterline and bolt hole is carried out.

WHAT ARE THE ADVANTAGES OF DUCT MACHINE?

 Advantages:

 

1. The body is relatively hidden. It would not be exposed to the outside like hanging air conditioners and cabinet air conditioners, which would affect the appearance. There is no need for indoor cover-up space and no need to consider the height of the ceiling at home.

 

2. The cost is relatively low. Compared with the central air conditioner, the price is cheaper, but the decorated effect is almost as beautiful as that of the central air conditioner, with maintenance cost being lower. Although the price is higher than that of hanging air conditioner, it is more high-end and practical.

 

3. Convenient use and maintenance. Its system is relatively simple and does not need to be managed by someone, but only needs regular inspection, which caters to the needs of many people who do not have enough time.

 

The main working principle of the air duct machine is to use the indoor air to be cooled by the indoor fan and then send the cold air back to the room, thus providing a more stable indoor temperature environment. Therefore, the air duct machine is installed and used by more and more families.

BRIEF INTRODUCTION OF FLANGE FORMING MACHINE

 Performance Description of Flange Forming Machine

Available to bend and roll channel steel and flat steel of different specifications; high efficiency, energy saving and material saving.

 

Structure and Working Principle

The equipment is mainly composed of three parts: the main machine, the hydraulic station and the electric control cabinet. The high-pressure oil output by the electric oil pump is sent into the working oil cylinder or motor through the high-pressure oil pipe. The high-pressure oil pushes the plunger in the working oil cylinder or motor to generate thrust and torque, and bends the profile through the mold parts.

 

Maintenance of Flange Forming Machine

Circuit: Pay attention to the cleaning of the circuit board, regularly clean the dust of the strong and weak electric boxes, keep the electric boxes dry and prevent moisture.

 

Oil circuit: Check all parts of the oil circuit to see whether there is oil leakage and deal with it in time. Prevent piston rod scratches and oil deterioration.

 

Machinery: Check the transmission part of the machine to see whether there exists abrasion phenomenon, and each butter nozzle to see whether it is blocked, and inject butter.

 

Other precautions: It is recommended to replace the hydraulic oil once a year and clean up the oil sludge in the oil tank. The water cooler shall be cleaned up in time to prevent the oil quality from accelerating aging due to the rise of oil temperature. Safety is a major concern. Circuit safety door switch, oil circuit pressure relief valve, mechanical safety stop and machine warning light must be checked whether work normally during maintenance.

 

Working Principle

The working principle of the flange forming machine is similar to that of the syringe used for injection. It is a technological process in which plasticized molten plastic (i.e. Viscous flow state) is injected into the closed mold cavity by means of the thrust of the screw (or plunger), and the product is obtained after curing and setting.

 

Injection molding is a cyclic process, and each cycle mainly includes: quantitative feeding-melting plasticizing-pressure injection-mold filling and cooling-mold opening and taking parts, taking out plastic parts and then closing the mold for the next cycle.
