Product Description

I. Overview
The PP and BP series positive pressure purging devices are a versatile product developed and designed by our company. The product adopts the world's most advanced pneumatic design concept, which not only meets market demands but also enhances practicality, making it more aligned with user requirements and better serving customers.
II. Scope of application
This device can be used as a ground motor, electrical cabinet, or other equipment with good sealing performance.
This device can be used in Zone 1 or Zone 21 explosion-proof areas, and after using this device, it can obtain explosion-proof certification for Zone 1 (Zone 21) together with the equipment.
III. Operating Principle
The pre-purging system can be used in Exe or Exn explosion-proof areas, with the addition of this purging device
It can meet the requirements for use in the aforementioned explosion-proof areas.
Before turning on the power supply (locally or remotely) of electrical equipment, the equipment must undergo
Ventilation is conducted to eliminate any flammable or explosive gases or dust that may infiltrate the enclosure of electrical equipment.
Pre-start ventilation refers to the use of air known to be free of combustible gases before the start-up of electrical equipment
(Or inert gas) replacement may involve replacing flammable and explosive gases or powders that may be present inside electrical equipment
The process of dust. The duration of the ventilation cycle is usually determined through ventilation tests
Sure.
After the ventilation cycle is completed, the external air source can be turned off. It does not have leakage compensation function
Yes. The principle of pre-start ventilation is as follows:
Extract clean compressed air or inert gas from a safe location.
-- The interior of the equipment has been pre-ventilated to eliminate any harmful gases or dust.
Measure the flow rate of "ventilation air" at the designated outlet and time the completion of the replacement.
--The positive pressure inside the motor housing prevents hazardous gases from the environment from entering the housing.
