Series Positive pressure explosion-proof instrument distribution cabinet (panel), hereinafter referred to as the positive pressure cabinet, is a cabinet used to install various non-explosion-proof detection instruments, analytical instruments, display instruments, and electrical components. It is designed, manufactured and inspected in accordance with the national standard B. "Explosion-proof Electrical Equipment for Explosive Environments and Positive Pressure Electrical Equipment". It can be widely used in dangerous places with explosive gas and dust such as petroleum, chemical industry, textile, medicine and so on.
The positive pressure cabinet introduces clean and complete compressed air into the positive pressure chamber through the intelligent control system in the explosion-proof control box and the pressure control system, so that a slight positive pressure is formed in the positive pressure chamber to prevent the leakage of dangerous gases and dust from the outside. Enter to achieve the purpose of explosion protection. This product has functions such as intelligent centralized control, LCD text display, automatic ventilation, delayed automatic power supply, pressure loss and gas replenishment, fault alarm and automatic power cut off in case of danger.

1. Structural Overview
The positive pressure cabinet is composed of a positive pressure chamber and a control chamber. The positive pressure chamber is used to install various non-explosion-proof instruments or electrical appliances, and the control chamber is controlled by an explosion-proof control chamber. box and pressure control system. The positive pressure cabinet shell is welded with cold-rolled steel plates, the ventilation pipes are made of galvanized steel pipes, and the incoming and outgoing cables are made of through-plate pipe joints and cable introduction compression devices. The front door is equipped with a glass display window to display instruments, indicators, etc.
