WQ(B) series explosion-proof submersible pump is mainly application for petrochemical industry, municipal engineering, underground pipe gallery project, tunnel engineering, urban engineering, hospitals, hotels, residential areas and other places.
Use Environment
1. Meeting the requirements of explosion-proof in accordance with the product flame-proof mark.
2. Voltage: 380V, 660V or 1140V, three phase, 50HZ (The above voltage and frequency commonly used in China, foreign customers can customize)
3. Medium temperature: 0-40ºC (above the temperature, there will be other hot water pump model).
4. Medium PH value: 5-9.
5. Medium weight: ≤1100kg/m3.
6. Maxium depth: 20m.
Main Application
The product is used for sewage discharge in the IIB/IIC factory where the temperature group is T1-T4 of combustible gas and explosible mixture of steam and air. It is suitable for coal chemical industry, petrochemical industry, municipal engineering, urban engineering, hospitals, hotels, residential areas and other places.
Flame Proof Main Point
When the exlosive gas mixture in the flame-proof submersible sewage pump motor explodes, flame-proof shell shall not be damaged and the internal flame will not cause further explosion. The parts of explosive shell are tested by water pressure tests according to GB3836.2-2000 standard to ensure maximum internal pressure explosion.
The flame-proof submersible sewage pump is marked as ExdIIBT4/ExdIICT4, which is suitable for factory IIB/IIC class, temperature group is T1-T4 of combustible gas and explosible mixture of steam and air. The maxium surface temperature must be in accordance with following list.
