Supply of submersible sand suction pump sand suction submersible pump ZSQ Shandong Stephen Cheung sand suction submersible pump wear ZSQ

ZSQ series slurry pump motor and pump coaxial sneaked into the media work of hydraulic machinery, the pump flow components using high alloy wear-resistant materials manufacturer, has good wear resistance, free passage, suitable for liquids containing relatively sediment, slurry, coal slurry, gravel and other media large solid particles. The products absorb the advanced design and manufacturing technology, in addition to increasing the main water pump impeller at the bottom of a mixing impeller external, can spray the deposited sludge hit into Turbulence is the pump to achieve a high concentration of transport in case of the absence of auxiliary devices. Unique sealing device can effectively balance the oil chamber outside pressure, the maximum protection of the mechanical reliability of the seal, using a variety of protective measures motor overheating protection, water protection, detection, capable of working in harsh conditions of long-term safe operation. ? ?? Yarn suitable for extraction building, silt, silt, tailing slurry, ore, iron sands, rivers, lakes, reservoirs, ports and other pumping sand dredging project, but also for iron and steel plants, power plants, iron ore plant, oil and other industrial and mining enterprises grit removal of sedimentation tanks, sewage treatment plants and other precipitates. Structural features 1. Machine for the dry-type pump, motor with oil chamber sealed manner, equipped with mechanical seal, can effectively prevent the high-pressure water and impurities into the motor cavity. 2. In addition to the main impeller, there are stirring impeller, capable of sludge deposited on the bottom of the stirred into turbulence after extracted. 3. impeller and stirring impeller flow components using high hardness high chrome cast steel, wear, corrosion, sewage capacity, through a larger solid particles. 4. Motor submerged, without suction lift limit, high slag suction dredging is more thorough. 5. Overall Equipment simplified allowed with additional stirring device or injection device, easy to operate, with a total investment of unit lowered. 6. stirring impeller direct access to the deposition surface, by controlling the concentration of dive depth. In the specific gravity of the medium through the installation of auxiliary equipment, increasing media concentration conditions of use. Power of 50Hz / 60Hz / 380V / 415V / 660V / 1440 three-phase AC power distribution transformer capacity is 2-3 times the motor rated capacity. 2. Medium temperature not exceeding 50 ℃, R type does not exceed 120 ℃, free of explosive gases. 3. Media maximum weight concentration of solid particles: 45% ash, slag was 60%. 4. Unit diving depth: not more than 20 meters, the minimum diving depth to submerge motor prevail. 5. Units in the medium work for the vertical position, the upper suspension positioning. Scope: 1. draw rivers, lakes, sea and other underwater sand 2. draw underwater silt rivers, lakes, sea, reservoirs, ponds, power plants, etc., and sand. 3. Transfer the powder slurries of various stone processing plant. 4. The tailings transport, a variety of mine tailings, slurry, pulp, coal slurry, slag, slag processing. 5. Transfer of various aqueous slurry of various solid slurry processing job items. 6. draw caisson wells in the mud. 7. sedimentation tanks, hydropower, reservoirs, rivers, plants, caisson, mines, ponds sediment cleanup. 8. draw a variety of power plant fly ash, coal. 9. draw all kinds of diamond sand, quartz sand, slag, slag solid particles. 10. The transport of sediment, slurry, coal slurry, gravel and other media containing large solid particles. 11. The gold sand, pumping iron ore. 3. Tips? 1) the presence of only a closed system outlet pressure, open system outlet pressure of 0.2) Pump Motor Power is (medium density 1.3) calculated in accordance with medium concentration, when used in higher concentrations should be re-delivery review. ? 3) When the media can not submerge motor or medium temperature is higher than 60 ℃, should be used in cooling shroud forced cooling, cooling water pressure 2-3kg, cooling water flow 5-8 cubic meters / hour. ? 4) pump outlet valve should be set, start the motor when the pump after power shut-off valve, until the normal operation of gradually opening the valve. ? 5) must be closed during shutdown valves cut off power to prevent Water Hammer cause serious damage to the pump. ? 6) To prevent pipe blockage, delivery period should rinse before the line shut down until the outlet water outflow so far. ? Cause Example Symptom possible solutions high current exceeds the rated current 1, pump and scrub anti-1, to adjust the gap 2. The device head is too low, the pump flow rate is too large to run 2, a valve to control the flow or a suitable replacement lift pump 3 , bearing damage 3, replace the bearing motor does not start buzzing 1, the voltage is too low 1, 2 to adjust the voltage to the rated motor running single phase 2, check the line, switched break 3, foreign body stuck in the pump 3 dead, remove foreign bodies 4, the impeller and the pump cover or suction plate with mill 4, impeller clearance adjustment to normal, no water or less water 1 reverse impeller 1, swap any two power supply lines 2, water treatment network is blockage 2, remove the blockage 3, leaking water intake 3, lowered position to a submerged pump 4, pipes leak or blockage 4, replace pipes or remove dirt 5, the actual head too high 5, select the appropriate pump head? insulation resistance falls 0.5MΩ less 1, a cable joint damage, to reprocess the cable connector 2, the stator winding insulation damage 2, replace the stator windings 3, 3 motor cavity water, removing the water, drying the windings 4, cable damage 4, repair the cable is not running smoothly severe vibration 1, badly worn impeller 1, replacing the impeller 2, miscellaneous dirt jammed rotating parts 2, 3 to clear debris, bearing damage 3, replace the bearing specifications model parameters (the specific size has kind)
