Flameproof submersible slurry pumps
The mining-use flameproof submersible sand-discharge pump is designed for mine conditions with explosive atmospheres such as gas and coal dust. It suits coal-mine roadways, shaft-bottom sumps, water pits and similar places, and discharges wastewater carrying solid particles such as rock cuttings and coal-grain slurry. The whole machine uses a modular upper and lower pump-and-motor structure, with the flameproof motor, mechanical seal and impeller coupled on one shaft. The pumped medium flows over the motor housing for self-cooling, and the minimum suction height is only 150 mm, so the pump works stably in both shallow water and deep submersion.
The pump head uses a single-stage, five-blade open impeller, with a grille cover at the suction inlet to stop large particles; the blade edges have a shearing action that cuts up solid debris and prevents the flow passages from clogging. The impeller, pump casing and main shaft are made of duplex stainless steel 2205, 304 stainless steel and 14Cr17Ni2 stainless steel respectively, and the mechanical seal is corrosion-resistant cemented carbide (WCCR). Being wear-resistant and corrosion-resistant, it can continuously convey untreated mine water containing corrosive particles over the long term.
The whole machine is fitted with an integral double-face mechanical seal; the seals are fixed independently and do not interfere with each other. The double spiral water grooves of the pump-side seal strengthen heat dissipation and drive corrosive particles away. The cooling jacket has an inspection port, so the motor is cooled well and runs continuously whether or not it is submerged. The pump can be submerged to 20 m and work continuously for 24 hours, supports an average of 30 starts and stops per hour, and suits a 660/1140 V, 50 Hz three-phase supply, with a medium temperature of no more than 40°C and a pH value of 4–10.
