Features of explosion-proof positive pressure cabinet
Contact number
This product mainly consists of cabinet, automatic control system, layout The gas system, alarm system, and power distribution system are composed of cabinets composed of a positive pressure chamber and an auxiliary chamber. The user's power distribution system components are installed in the positive pressure chamber, and the automatic control system is installed in the auxiliary chamber.
Cabinet-type products adopt
cabinet frames, with the main and auxiliary panels having left and right structures, cable trench seat installation, lower cable entry, front door operation, and rear door inspection.
The box-type product adopts a high-quality steel plate welded structure. The main and auxiliary disks are upper and lower structures. They are hung-type installation, with lower cable entry, front door operation and maintenance.
The piano table type product is made of high-quality steel plates that are folded and welded. The main and auxiliary plates have front and rear structures, seat-type installation, lower cable entry, piano table operation, and rear door maintenance.
According to the air intake method, it is divided into ventilation type and compensation type. The ventilation type provides uninterrupted and continuous air supply. The working heat of the components in the positive pressure cavity can be taken away with the air path. It has good heat dissipation function and is suitable for solving the heat dissipation problem of high-power explosion-proof inverters. The compensation type provides intermittent air supply. The positive pressure chamber must have good sealing performance to ensure low air consumption.
The user must provide a gas source, which is required to be purified air or nitrogen. The gas source pressure is
~
Usually the instrument air average at the user site is Requirements can be met.
The steel plate material is generally
cold-rolled steel plate, and
stainless steel can also be selected according to user requirements.
Explosion-proof positive pressure cabinet function description
Contact number
The product is equipped with a ventilation chain. Before the product is put into operation, it can only be replaced by the inner cavity of the main panel. After the specified ventilation time and volume are reached, make sure that the flammable and explosive gases are blown out of the main panel before the auxiliary panel can receive power and start to detect the air pressure of the main cavity to ensure that the electrical components have been removed when the product is put into operation. Clean media is effectively isolated.
Only when the air pressure in the main disk cavity meets the specified air pressure requirements, the automatic power switching system in the secondary disk will send power to the main cavity.
The working air pressure in the main disk cavity is
.
When the air pressure is higher than
, the automatic control system automatically closes the air inlet or opens the exhaust valve, and automatically adjusts the internal air pressure to ensure that the product is not deformed and damaged due to the impact of high air pressure.
When the air pressure is lower than
, the automatic control system automatically alarms, opens the air intake, and automatically adjusts the internal air supply. When the air supply is successful, it automatically returns to normal. If it fails, the internal air pressure drops to
, the system can be set to automatically power off if necessary.
The secondary disk automatic control system monitors continuously and displays various pressure parameters in the main disk cavity.
