PXK防爆正压柜功能特色
◆为专用于2区而设计的一种正压防爆柜，pz系列防爆正压柜标志换气时间和流量，安装了节流阀和安全阀等安全装置，采用纯气动控制方式，无需电源，用户按提示进行相应的调试、运行。
◆pz型正压柜适用于2区爆炸性气体环境或22区可燃性粉尘环境;
◆产品无主、副盘，采用气动元件控制，控制部分包括减压阀、气源压力表、正压腔压力表换向阀和排气阀等;
通过精确计算设计相应控制气路大小规格，正压控制准确、可靠，是我公司开发的新一代正压防爆产品;
用户根据提示进行换气操作，换气完成后可向柜内供电。正常工作时压力在200Pa~600Pa之间，当压力高于1000Pa时，安全阀自动打开排气，自动调整内部气压，保证产品不受高气压冲击变形损坏，当压力低于100Pa时，气动指示灯报警，当气源故障，柜内压力长
期过低时，应切断前级电源:
◆正压控制部分不间断连续监控，并显示正压腔内压力参数;
◆不间断连续供风，正压腔内电器元件的工作热量可随时带走，具有良好的散热功能。内部可装检测仪表、分析仪表、显示仪表、低压电器、变频器、软起动器、计算机等，整台设备可作为设备起动、控制、中央信号处理及控制系统:
◆同型号产品可多台并联运行:
用户提供气源时，须配备洁净空气或惰性气体气源，一般情况下，现场的仪表气源可满足要求，气源压力0.2MPa-0.8MPa:
外壳材质可选用不锈钢板焊接的产品，具有很好的防腐性能，可应用于强腐蚀要求的石油、化工、轮船等场所。
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 --------- Scope of application
1. Suitable for explosive gas environment zone 1, zone 2 dangerous places;
2. Suitable for IIA, IIB, IIC explosive gas environment;
3. Applicable to combustible dust environment 20 zone, 21 zone, 22 zone;
4. Suitable for temperature group T1-T6 environment;
5. This product is suitable for petrochemical, offshore drilling platform, metallurgy, medicine, light industry, textile, wine, paint, coatings, food, biological engineering, aerospace engineering and military facilities and other factories;
Explosion-proof positive pressure cabinet --------- Implementation standard:
GB3836.1, GB3836.2, GB3836.3, GB12476.1,
1. Control power supply: 220V 380V AC.
2, running positive pressure value 150Pa-900Pa

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.
