[Pump News] Pump want to be able to operate the normal operation of the pump, it can not be separated from the day-to-day maintenance, today Xiaobian come and we talk about, vertical pipe centrifugal pump installation and routine maintenance methods are there? Vertical Pipeline Centrifugal Pump First, the vertical pipe centrifugal pump Vertical pipe centrifugal pump installation technology is the key to determining the installation of centrifugal pumps that suction. This height refers to the vertical distance from the surface of the water source to the centerline of the centrifugal pump impeller. It is not confused with the allowable suction height. The allowable vacuum height indicated on the pump manual or nameplate means the vacuum value on the water inlet section of the pump, But also at 1 standard atmospheric pressure, the water temperature of 20 ℃, the test was measured and determined. It does not consider the condition of the water flow after the water supply pipe is matched. The pump installation height should be allowed to suck vacuum height deducted after the loss of suction pipe head, the remaining part of the value, it is necessary to overcome the actual terrain water absorption height. Pump installation height can not exceed the calculated value, otherwise, the centrifugal pump will not pump water. In addition, the impact of the calculated value is the size of the suction pipe lift loss lift, it is appropriate to use the shortest pipe layout, and try to install less elbow and other accessories, but also consider the appropriate with some larger diameter pipes to reduce the flow rate within the pipe. It should be noted that the elevation and temperature of the vertical pipeline centrifugal pump installation site is different from the test conditions, such as the local elevation of 300 meters above sea level or pumping water temperature exceeds 20 ℃, the calculated value to be amended. That is, the atmospheric pressure at different altitude and the saturated steam pressure above 20 ℃. However, when the water temperature is below 20 ℃, the saturated steam pressure is negligible. From the pipeline installation technology, water pipes require strict sealing, can not leak, leaking, or will undermine the centrifugal pump inlet at the vacuum, so that the centrifugal pump to reduce the amount of water, even when the pump is not pumping. Therefore, we should conscientiously do the work of the interface of the pipeline to ensure the construction quality of pipeline connection. Second, the vertical pipe centrifugal pump maintenance and maintenance operation and maintenance 1, the inlet pipe must be highly sealed, can not leak, leak; 2, prohibit the long-term operation of the pump cavitation; 3, prohibit the pump at high flow 4, regularly check the value of the motor current in the pump operation, try to make the pump run in the design conditions; 5, the pump in the operation should be someone care, so as to avoid accidents; 6 , The pump should run for 500 hours each time to refuel the bearing; 7, long-term operation of the pump, due to mechanical wear and tear, so that unit noise and vibration increases, parking should be checked, the need to change into vulnerable parts and bearings, unit overhaul is generally One year Mechanical seal maintenance and repair 1, mechanical seal lubricating fluid should be clean without solid particles; 2, non-mechanical seals in the dry work; 3, before starting the pump (motor) should be circled several times to avoid sudden start causing mechanical seal Fracture damage.
