The impeller is made of cast or stamping, with high precision, high thrust, beautiful appearance, compact structure and compact structure. It adopts the multi-pole motor hybrid series products, direct coupling structure, low energy consumption and high efficiency.
The motor’s submersible mixer stirrer windings are class F insulated with protection class IP68. The use of sewage treatment plant aeration system, greatly reducing the system’s energy consumption, so that the oxygen content was significantly improved, and can effectively prevent. According to process requirements, direct diving mixing can be equipped with baffles.
1.Check the submersible gear box.
Submersible gearbox has high precision and good heat treatment, but it also has the phenomenon of gear teeth and the gear shaft is not axial clearance. We carried out a thorough cleaning of the gearbox and carefully examined gears, gear shafts, bearings. There is no pitting in the inner and outer ring and the surface of the roller, and the whole quality is good. The gears are smooth, no pitting, overlapping, normal backlash, no obvious wear on tooth profile. The radial and axial clearance are normal. Axial clearance is reasonable, hand wheel output shaft free flow, no interference, no abnormal sound. Therefore, the failure of the gearbox is eliminated.
2.Submersible mixer mechanical seal inspection
Mechanical seals are the most prone to failure of submersible fittings, often due to wear and tear of the mechanical seal failure, seal the cavity water. We first disassemble the mechanical seal assembly, which consists of two sets of mechanical seals, the skeleton oil seal, the output shaft, the bearing, the outer cover and the end cap and so on part to carry on the cleaning and the inspection, and inspects the bearing seat and the output shaft size, has not found. The mechanical seal is in place to eliminate the possibility of failure.
Suitable for industrial and municipal sewage treatment plants aeration tanks and anaerobic tanks, pool water cycle and nitrification, nitrogen and phosphorus removal.
