WQB, QWB, BQW, BWQ explosion-proof non-clogging submersible sewage pump is a new type of explosion-proof equipment designed and manufactured on the basis of the international advanced explosion-proof submersible sewage pump technology, based on national standards. Now to introduce the structural characteristics of riot sewage pumps and anti-riot points. Riot sewage pump First, the anti-riot sewage pump Product Structure Features The pump consists of explosion-proof motor and pump coaxial submersible sewage pump assembly, enclosure protection grade IP68, explosion-proof grade ExdIIBT4. It is suitable for coal mine, chemical industry, petroleum and other industries with methane or coal dust explosive gas mixture safety discharge and other explosion-proof places. Thoroughly solve the general submersible sewage pump no special explosion-proof devices dangerous, thick pump can not suction larger particles, and sewage pump easy to plug the problem. Flameproof motor is located in the upper part of the pump, flameproof motor insulation level F grade. Shaft seal is a combination of rotary seal ring and double-end mechanical seal, rotary seal ring to prevent the invasion of mud and reduce pump pressure directly on the mechanical seal, played a role in the first seal line of defense, double-end machine Sealed into two groups, the first group on the pump side for the initial seal used to seal the sewage, the second group on the motor side of the secondary seal, used to seal the oil seal, a full set of mechanical seal immersed in the No. 20 turbine oil To seal cooling and lubrication. Second, the anti-riot sewage pump explosion points 1, such as the pump internal explosive mixture explosion, flameproof enclosure is not damaged, and the internal explosion can not flameproof joints, causing the explosion of an explosive mixture. 2, the components of the flameproof enclosure are made according to GB3836 items 1, 2 and 3 of the hydrostatic test piece by piece to ensure the maximum internal explosion pressure. 3, the flameproof joints between the parts, the length of the gap, roughness are in line with the provisions of GB3836.2. 4, the flameproof shell bolts are equipped with anti-loose washer gasket. Bolt head located in the protection ring, to prevent their own off. 5, the base, cover, shaft, front cover, junction box cover, wiring block, wiring screw, wiring kit are explosion-proof parts. Supplied with 10 meters of explosion-proof cable.
