Introduction of the products:
WQB, QWB, BQW, BWQ explosion-proof submersible sewage pump with infarction, non-progressive predecessors in the domestic technology, explosion-proof submersible sewage pump is basically, based on a country-scale entry of the old design of explosion-proof equipment produced. When the pump from the explosion-proof electrical pump different thoughts and on-axis group lost demolition of submersible sewage pump, inner shell protection grade IP68. It is useful to have an explosive gas mixture of methane or coal dust coal materials, chemical agriculture, oil and other industries Zhongping just resting and the rest of explosion-proof arrangements for occasions to use. Toru top line summary of the general explosion-proof submersible sewage pump installed with special risks, weak pump can not pump call smaller particles, as well as sewage pump difficult infarction difficulties. Construction features Explosion-proof electric pump is located in the lower part of the idea, explosion-proof electrical machine continued geo-static grade of F grade. Seals to euphemism for war-style secret Kai Wan Shan Kai group close to open-end machine defeated, studied in America, owned by euphemism-style thin seal ring will be able to avoid the mud invasion into the diaphragm also has reduced pressure on the indirect reduction in the mechanical seal, only rare letters to the first talking to do with the offensive line, single-ended where mechanical seal into two groups, the first group is for the pump is only the beginning of the opening to seal dilute sewage, the first two groups are in the motor for the two main seal, with the heading for the smooth Oil leaked into the only seal, mechanical seal immersed in homogeneous sets of turbine oil 20 seals the cold to play outside, and Run-astringent to do with it. Explosion-proof to face
1, such as the pump outside the explosive mixture developing health explosion, explosion-proof in the shell is not destroyed, and the external explosion can not pass intercourse flameproof power surface, sparked an explosive mixture within the explosive material. 2, group defeated in the shell explosion-proof machine according GB3836 item designated by the first pieces of 1,2,3-fire pressure to do experiments in order to protect the smallest of the explosion could have suffered an external pressure, with simultaneous interpretation. 3, the entire explosion-proof cross between the opening part, the small degree of clearance, both fit GB3836.2 Cuzhuo degree of delineation. 4, convergence in shell explosion-proof bolts are free anti-bear cushion split washer. Bolt tail is located outside the ring is being maintained to avoid wearing down from the ending. 5, plane seat, on the lifting, shaft, rear axle flip, flip junction box, wiring blocks, wire screw, wire sets are non-explosion-proof machine. Random explosion-proof cable with 10 meters.
