PXK explosion-proof positive pressure cabinet is to input gas into the cabinet, so that the pressure inside the cabinet is higher than the external pressure, forming a safe positive pressure environment. Thus, combustible gas or combustible dust is prevented from entering the cabinet, so that the ordinary components in the cabinet can operate normally. Positive pressure cabinet has two kinds of materials, one is Q235 steel plate welding material, the other is 304 stainless steel material. The positive pressure cabinet has three kinds of structures: single cavity left and right structure, up and down structure, piano table structure. It is also widely used in petrochemical, offshore drilling platforms, metallurgy, medicine, light industry, textile, wine, paint, coatings, food, biological engineering, aerospace engineering and military facilities and other factories.

PXK explosion-proof positive pressure cabinet features
◆ A positive pressure explosion-proof cabinet specially designed for the 2 zone, pz series explosion-proof positive pressure cabinet marks the air exchange time and flow, and is installed with throttle valve and safety valve and other safety devices, using pure pneumatic control mode, no power supply, the user carries out the corresponding debugging and operation according to the prompt.
◆pz type positive pressure cabinet is suitable for explosive gas environment in zone 2 or combustible dust environment in zone 22;
◆ The product has no main or auxiliary disc, and is controlled by pneumatic components. The control part includes pressure reducing valve, air source pressure gauge, positive pressure chamber pressure gauge reversing valve and exhaust valve, etc.
Through accurate calculation and design of corresponding control gas path size specifications, positive pressure control is accurate and reliable, is a new generation of positive pressure explosion-proof products developed by our company;
The user can carry out air exchange operation according to the prompt, and supply power to the cabinet after air exchange is completed. Normal working pressure between 200Pa~600Pa, when the pressure is higher than 1000Pa, the safety valve automatically opens the exhaust, automatically adjust the internal air pressure, to ensure that the product is not damaged by high pressure impact deformation, when the pressure is lower than 100Pa, the pneumatic indicator alarm, when the air source failure, the cabinet pressure is long
When the period is too low, the preceding power supply should be cut off:
◆ The positive pressure control part is continuously monitored and displays the pressure parameters in the positive pressure chamber;
◆ Uninterrupted continuous air supply, the working heat of the electrical components in the positive pressure chamber can be taken away at any time, with good heat dissipation function. Inside can be installed detection instrument, analysis instrument, display instrument, low voltage electrical appliances, frequency converter, soft starter, computer, etc. The whole equipment can be used as equipment starting, control, central signal processing and control system:
◆ Multiple parallel operation of the same model:
When the user provides the air source, it must be equipped with clean air or inert gas source. In general, the on-site instrument air source can meet the requirements, and the air source pressure is 0.2MPa-0.8MPa:
Shell material can be selected stainless steel plate welding products, with good anti-corrosion performance, can be used in strong corrosion requirements of petroleum, chemical, ships and other places.
