Olympic Village sewage pump repair | Deep Blue Nanjing centrifugal agent phone | professional repair Deep Blue sewage pump centrifugal pump use commissioning shall meet the following requirements: ① driver should turn the steering pump is the same; ② pipeline pump and identify coaxial steering pump; ③ respective fixed connection should be no loose parts, lubricating parts filling lubricant specifications and quantities shall comply with equipment technical documents; ④ there are parts of the pre-lubrication requirements should be required to conduct pre-lubrication; ⑤ each indicating instruments, safety devices should be sensitive, accurate and reliable; ⑥ disk drive should be flexible, no abnormal phenomenon; ⑦ high temperature pump before commissioning the pump should be preheated, the temperature should rise evenly, the temperature rise should not exceed one hour 50 ℃; the temperature difference between the surface of the pump working medium inlet of process piping should not exceed 40 ℃; ⑧ set the connection means to eliminate the impact of the rise, setting a bypass connecting means to provide cooling water. Centrifugal operation should pay attention to the following points: ① Prohibition run dry, do not adjust the suction port to reduce emissions, prohibit running at too low a flow rate; ② monitor when running completely prevent the stuffing box leaks, replace the packing box to With new filler; ③ ensure adequate mechanical seal flushing water flow, water-cooled bearing prohibit the use of excess water; ④ lubricants do not use too much; ⑤ the recommended period for inspection. The establishment of operational records, including operating hours, packing adjustment and replacement, lubricant and other maintenance measures and time. Centrifugal pump suction and discharge pressure, flow, temperature, and vibration input power, lotions and bearings should be measured regularly records. ⑥ centrifugal host is to rely on atmospheric water pumped at low height, and atmospheric pressure can only support about 10.3m of the water column, so centrifugal hosts out of the water 12 meters not working. Maintenance 3.1, pump mechanical seal failure of centrifugal pump downtime is primarily caused by the failure of the mechanical seal. Failure of performance mostly leak, leak causes are the following: ① static ring sealing surface leakage, the main reasons are: the end surface flatness, roughness does not meet the requirements, or surface scratches; between the end face of particulate matter, resulting in two the end face is not the same operation; installed in place, the wrong way. ② compensation ring seal leakage, the main reasons are: gland deformation, uneven preload; not properly installed; seals do not meet quality standards; seal selection wrong. Actual results show that the failure of most of the parts of the sealing element is dynamic and static ring face, centrifugal pump mechanical seal dynamic and static ring face appear cracks are common failure phenomenon, mainly are: ① When installing the sealing surface of the gap is too big, rinse too late to take away the heat generated by friction; fluid leakage from the sealing surface of the gap go, resulting in the end face of overheating and damage. ?
