Shandong Jining Star Mining Equipment Co., Ltd. professional manufacturer BQS flushing pump mine explosion-proof submersible pumps. Flameproof submersible flushing pump installation, adjustment 1. Install the technical requirements of a. Pumps should be installed in the water tank or dedicated infrastructure in line with their working conditions, the available lifting, can also be directly mounted on the bottom, Avoid pump suction strainer into the mud work. b. pumps should be installed perpendicular to the surface of the water so that it seals the system to work optimally, but in the case of awkward posture can also be free to install. Submerged pump should be installed so that the water filter, note should be able to maintain the pool water inflow filter partially submerged electric pump. c. pump operating point should be installed close to the rated state occasions. d. Pump pressure value should be matched with the pump rated head of the drain line. e. appropriate to increase the drainage pipe diameter and reducing right-angle turn can reduce line losses 2. Setup and adjustment of a. Before installing the pump to respond conduct a comprehensive inspection. Turbine rotation should be light and freely, without jamming phenomenon; the motor insulation resistance should be greater than 100 megohms. b After mounting the electrical connections. Note the rated voltage. c. rated power 11kW and below the pump direct start, 11kW more than the pump should start indirect, such as start after pump flow, head is too small or hydraulic shock sound, then the pump is reversed, should Three-phase wiring swap any two phases, namely forward. Fourth, use, maintenance, maintenance and precautions 1. Before each turn, you should check whether the abnormal pump. 2. The non-frequent start, two starts interval is: not less than 2 minutes start-load; load of not less than five minutes to start. 3. To prevent the pump suction strainer into the sediment deposition should not be prolonged use of pump delivery can be solidified cement mortar. 4. When the pump in pumping high concentrations of sediment down the process, should be switched on again before sedimentation, otherwise, should be promptly removed from the water pump, the pump upright, into the outlet pipe inject water, rinse the pump After storage or re-use of the boot. 5. pump every 2000 hours, replace the oil seal and the same type of mechanical seals, cleaning bearings and inject lithium grease. 6. pump every 100 hours of use, should be checked cold winding insulation resistance is less than 100MΩ, it should be shut down for repairs. 7. Long-term disabled pump, should be cleaned, stored in a dry room, open the pump cover before re-use, turn the wheel to burn out the motor antirust dead. 8. When carrying, do not pull on the cable or damaged parts, otherwise it will affect the safe use. 9. After repaired pumps, motors and hermetically sealed chamber section should test 0.2MPa, which lasted five minutes should be no leakage. 10. In the following cases, should immediately stop processing:. A sound and vibration anomalies. b. No water or a significant reduction in the amount of water. c. Insulation resistance decreased significantly. d. cable breakage. e. protector trip.
