When we use the
Horizontal Slurry Pump, be sure to sell the relevant operating practices to operate. In general, the operation of the horizontal
Slurry Pump is divided into four major steps, as long as the implementation of the following provisions step by step, you can effectively reduce the risk of horizontal slurry pump failure, extend the life of horizontal slurry pump. Detailed Horizontal Slurry Pumps Operational Specifications First, the pre-operation inspection 1, check all the bolts of the slurry pump is tightened, with particular attention to the corner bolts must be fastened and reliable 2, the pipeline and the valve and the pump must be respectively Support, and flange bolts to tighten, to avoid leakage slurry 3, check the direction of rotation of the motor and the arrow pointing to the pump, the test motor rotation should be separated from the pump 4, the use of direct drive to check the coupling The elastic pad is complete and correct; belt drive to see whether the belt wear, lack of tightness is moderate 5, check the motor shaft and shaft are concentric; pulley is aligned 6, with the hand crank, the pump and the motor should not be tight Astringent and friction 7, check the lubrication system grease or oil filling 8, the slurry pump to start before the shaft seal water (mechanical seal for the cooling water), water to be clean, water pressure to be appropriate (packing seal and single Mechanical seal pressure is greater than the pressure of the pump cavity 0.1-0.15Mpa), at the same time to start the pump inlet valve, close the pump outlet valve 9, check the valve is flexible and reliable Second, the pump start running and monitoring 1, slurry pump before operation The pond filled with water, turn on the pump inlet valve, turn off the pump outlet valve. 2, and then start the pump, the pump starts slowly open the pump outlet valve 3, at the same time according to the need to put slurry into the pool 4, the size of the pump outlet valve opening and closing speed, the pump does not vibrate and the motor does not exceed the rated current Master, until the page can be stabilized at 0.5-1 m above the inlet pipe position 5, regular inspection and timely adjustment packing gland or replacement packing 6, pay attention to check the bearing operation, not into the mine operation, such as the bearing into the mine must Immediately stop cleaning for oil change 7, the bearing temperature must not exceed 75 ℃ 8, if the start of operation, bearing fever can stop the pump to run again bearing cooling, if still serious fever, you must stop processing 9, timely adjustment to the amount of ore or Fill the water or the pump outlet valve, under any circumstances to prohibit the pump to pump the vibration caused by 10, prohibit any lumpy material into the pump, to prevent clogging or damage to the pump lining 11, according to the pump oil level promptly refueling 12, check the water seal Water pressure is normal, is clogged, the water is sufficient, the water quality is clean 13, check the various parts of the lubricating oil, the oil temperature is normal, the lubricating oil to be clear, oil Temperature not exceeding 50 degrees 14, observe the motor current is normal, the motor has no abnormal response Third, stop the pump 1, when the above process is completed, continue to maintain the pump operation 5-20 minutes to send clean water, and then stop the pump 2 , To be stopped after the slurry pump operation, and then stop the shaft sealing water or mechanical seal cooling water Fourth, the daily maintenance of the slurry pump 1, slurry pump suction piping system does not allow leakage phenomenon, into the pump grid In line with the pump can pass the particle size requirements, in order to avoid large particles of materials or fiber materials into the pump, causing blockage 2, check and replace the consumable parts in time, the assembly should be correct, the gap adjusted in accordance with the provisions of reasonable, no austerity friction phenomenon 3, the shaft Seal water pressure, water to meet the provisions of the packing at any time to adjust or change the degree of tightness, do not cause the shaft seal leakage timely replacement sleeve 4, the replacement of bearings, we must ensure that the bearing assembly clean, clean oil, pump operation When the bearing temperature is generally not more than 60-65 ℃, the maximum does not exceed 75 ℃ 5, to ensure that the motor and pump concentricity, to ensure complete and correct elastic coupling in the coupling, after the damage should be promptly more 6, the pump assembly to ensure correct installation and piping systems, solid and reliable
