PXK防爆正壓柜功能特色
◆為專用于2區(qū)而設計的一種正壓防爆柜，pz系列防爆正壓柜標志換氣時間和流量，安裝了節(jié)流閥和安全閥等安全裝置，采用純氣動控制方式，無需電源，用戶按提示進行相應的調試、運行。
◆pz型正壓柜適用于2區(qū)爆炸性氣體環(huán)境或22區(qū)可燃性粉塵環(huán)境;
◆產品無主、副盤，采用氣動元件控制，控制部分包括減壓閥、氣源壓力表、正壓腔壓力表換向閥和排氣閥等;
通過精確計算設計相應控制氣路大小規(guī)格，正壓控制準確、可靠，是我公司開發(fā)的新一代正壓防爆產品;
用戶根據提示進行換氣操作，換氣完成后可向柜內供電。正常工作時壓力在200Pa~600Pa之間，當壓力高于1000Pa時，安全閥自動打開排氣，自動調整內部氣壓，保證產品不受高氣壓沖擊變形損壞，當壓力低于100Pa時，氣動指示燈報警，當氣源故障，柜內壓力長
期過低時，應切斷前級電源:
◆正壓控制部分不間斷連續(xù)監(jiān)控，并顯示正壓腔內壓力參數;
◆不間斷連續(xù)供風，正壓腔內電器元件的工作熱量可隨時帶走，具有良好的散熱功能。內部可裝檢測儀表、分析儀表、顯示儀表、低壓電器、變頻器、軟起動器、計算機等，整臺設備可作為設備起動、控制、中央信號處理及控制系統(tǒng):
◆同型號產品可多臺并聯運行:
用戶提供氣源時，須配備潔凈空氣或惰性氣體氣源，一般情況下，現場的儀表氣源可滿足要求，氣源壓力0.2MPa-0.8MPa:
外殼材質可選用不銹鋼板焊接的產品，具有很好的防腐性能，可應用于強腐蝕要求的石油、化工、輪船等場所。
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;

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.
