First, the test run of the fluoroplastic centrifugal pump should meet the following requirements:
1 The steering of the drive should be the same as the steering of the pump;
2 Identify the steering of the pipeline pump and the coaxial pump;
3 The fixed joints should be free from looseness. The specifications and quantity of lubricants for each lubrication part should meet the requirements of the equipment technical documents;
4 The parts with pre-lubrication requirements shall be pre-lubricated as required;
5 All indicating instruments and safety protection devices should be sensitive, accurate and reliable;
6-disc should be flexible and free of abnormalities;
7 The high temperature pump should be preheated before the test run, the temperature should rise evenly, the temperature rise per hour should not exceed 50 °C; the temperature difference between the surface of the pump body and the process pipe with working medium inlet should not exceed 40 °C;
8 Set the connection device to eliminate the influence of temperature rise, and set the bypass connection device to provide cooling water source.
Secondly, the following points should be noted when operating the fluoroplastic centrifugal pump :
1 It is forbidden to run without water, do not adjust the population to reduce the displacement, and prohibit running under too low flow rate;
2 Monitor the operation process, completely prevent the stuffing box from leaking, and use new packing when replacing the stuffing box;
3 to ensure that the mechanical seal has a fully flushed water flow, water-cooled bearings are prohibited from using excessive water flow;
4 Do not use too much lubricant;
5 Check according to the recommended cycle. Establish operational records including hours of operation, adjustment and replacement of packing, addition of lubricants and other maintenance measures and time. Pump suction and discharge pressure, flow, input power, wash and bearing temperature and vibration conditions should be measured periodically.
The main engine of the 6 pump relies on atmospheric pressure to pump the low water to the high place, while the atmospheric pressure is only able to support the water column of about 10.3m, so the main engine of the pump can not work 12 meters away from the water surface.
