Liquid tank air supply outlet

The following is a detailed introduction to the liquid tank air supply outlet:
Structural design
Box body: Mainly cold-rolled steel plates are used for connection by welding. All welds are specially sealed with glue to prevent air leakage. The surface of the box is usually treated with electrostatic powder coating to enhance corrosion resistance.
Diffuser plate: It is fixed to the box body by fixing bolts, making installation and disassembly relatively convenient, and facilitating later maintenance and component replacement.
Liquid tank high-efficiency filter: There are sealing grooves around the frame of the filter, which are nested with the knife edges around the box to form an airtight seal. The filter press can rotate freely, facilitating the safe and quick replacement of the filter. Moreover, it can prevent air from leaking through the frame and the knife edge of the box from sliding out of the rubber groove of the filter frame.
Air valve: A butterfly-shaped air valve is installed in the air inlet at the top of the box. On the side of the bottom of the box, there is a rotating valve regulating device. The two are connected by a metal regulating rod. This device can be directly rotated from the bottom to control the butterfly valve and regulate the air volume entering the clean room.
Working principle
The air enters the box of the high-efficiency supply air outlet of the liquid tank through the air duct and then passes through the high-efficiency filter to remove dust, bacteria, and other tiny particles. The air that has been filtered by the high-efficiency filter is then evenly distributed to the surroundings through the diffuser plate, forming a uniform air flow distribution in the room, thereby achieving the effect of air purification.
Performance characteristics
High-efficiency filtration: It can effectively remove dust, bacteria, and other tiny particles in the air, ensuring the cleanliness of the air. The filtration efficiency grade can reach H13-H14.
Good sealing performance: It adopts a liquid tank sealing method. The knife-edge type is inserted into the jelly glue of the liquid tank filter to achieve sealing, avoiding the leakage of supply air from the installation gap. It can pass the integrity test of DOP dust generation at one time.
Uniform and stable airflow: Compared with traditional supply air outlets, liquid tank supply air outlets smooth the airflow through liquid tank technology, reducing the generation of turbulence. They have better airflow uniformity and stability, and can more effectively control the airflow direction and velocity.
Excellent noise control: Due to the smooth airflow effect of the liquid tank technology, the noise generated by the liquid tank supply air outlet is relatively small, reducing noise pollution.
Easy maintenance: The installation and disassembly of the diffuser plate and the filter are relatively convenient. When replacing the filter, the operation can be directly carried out at the bottom of the ceiling without removing the box on the ceiling system.
Application field
It is widely applied in places with high requirements for air cleanliness, such as operating rooms, intensive care units, biopharmaceutical workshops, semiconductor manufacturing workshops, liquid crystal manufacturing workshops, precision mechanical processing workshops, optical laboratories, etc. in hospitals.
Installation Points
Box leakage inspection: Inspect the weld areas around the box shell, especially the joint parts of the box at the air outlet end of the filter. They must be fully welded or treated with glue both inside and outside the joints. Check the sealing cutting edges inside the box. The four edges should be straight and the cutting surfaces should be basically on the same plane. Check the corners where the cutting edges meet. The weld seams should be continuous and ground, and there should be no welding slag, protrusions, pits, etc.
Liquid tank 100-level frame leakage inspection: Inspect the frame splicing parts. The sealing at the joints is the key. Check the overall flatness of the frame. If the joints become loose and the frame deforms after being subjected to force by people or others, it needs to be adjusted again. All the joint sections of the adjusted frame need to be sealed with glue.
Re-inspection of liquid tank filter: Due to the special structural form of the liquid tank filter, it is necessary to conduct an appearance inspection of the process requirements for potting and interface sealing. The on-site installation of the liquid tank filter should be completed in one operation.
Size specification
The liquid tank supply air outlets come in a variety of standard sizes, such as GH320, GH484, GH610, GH630, GH726, GH915, GH968, GH1220, GH945, GH1260, etc. At the same time, special sizes can also be customized according to customer requirements.
