Submersible pump regular maintenance guide

Submersible pump due to the need for a long time in the water, vulnerable to sediment and fluid and other substances erosion, especially after the debris intruded into the pump body, easily lead to pump failure or damage, so the diving Periodic inspection and maintenance of the pump is necessary. 1, replace the seal ring: After long-term use in the sewage medium, the gap between the impeller and the seal ring may increase, resulting in reduced pump flow and efficiency, turn off the brake, the pump hoisted, remove the bottom cover, remove Seal ring, according to the actual size of the impeller ring with seal ring, the gap is generally about 0.5mm. 2, submersible pump long-term need, should be cleaned and lifted in ventilated and dry place, pay attention to antifreeze pump. If placed in water, run at least 30 min every 15 days (do not dry) to check its function and suitability. 3, cable inspection at least once a year, if damaged please give replacement. 4, at least once a year inspection motor insulation and fastening screws, if the motor insulation down to find someone to repair, if the fastening screws loose, please re-tighten. 5, the submersible pump in the factory has been injected into the right amount of oil, used to lubricate the mechanical seal, the oil should be checked once a year. If you find water in the oil, it should be let go, replace the oil, replace the gasket, tighten the screw plug. After three weeks, it must be rechecked. If the oil becomes emulsion, the mechanical seal should be inspected and replaced if necessary. 6, submersible pump operation failure, please give troubleshooting methods are excluded, if still can not be resolved, and can not determine the reason, do not indiscriminately dismantling chaos, should immediately find someone to repair. Submersible pump in addition to regular maintenance, but also should not avoid frequent disassembly, otherwise it is easy to cause permanent damage to the body.

1. Product introduction

Coal Columnar Activated Carbon with high quality anthracite as raw material, its appearance is generally black cylindrical Activated Carbon. Generally by powder materials and binder by kneading, extrusion molding by carbonization and activation processes, has developed pore structure, large surface area, strong adsorption capacity, high mechanical strength, easy to regeneration and low cost. The coal column activated carbon has excellent and broad development prospects in the future market.

2. Application

Column activated carbon is widely used in industry and agriculture, such as petrochemical industry CAUSTIC-FREE (refined mercaptan), ethylene desalted water (refined filler), catalyst (palladium, platinum, rhodium, etc.), water purification and sewage treatment; water treatment and protection in electric power industry; governance, waste gas and harmful gas purification in environmental protection industry; chemical catalyst and carrier, gas purification, solvent recovery and oil decolorization, refining in chemical industry.

3. Adsorption purification principle and process

a. Activated carbon widely used in city drinking water advanced purification and sewage treatment, removing more than chloride, deodorization; high pure water purification materials, advanced artificial mineral production raw materials; large-scale boiler removed the COD and other harmful impurities, which can improve the boiler efficiency and prolong the service life of the boiler; it also can effectively remove the COD of water, pigment, odor and other toxic. Large Granular Activated Carbon can fill the filter and purify the air.

b. Activated carbon widely used in industrial waste-water treatment, effectively deodorization, effectively remove harmful substances to improve water quality. Most powdered activated carbon used for sewage treatment sometimes used for granular activated carbon. Generally activated carbon used in water treatment, the surface area is not too large, but the transition pore has more and larger average pore size.
