Normal performance and lubrication of centrifugal pump

Centrifugal pump in the pump, lubrication standards commonly used and master the knowledge of pump equipment performance is good or bad, the normal operation of the pump is from the analysis of this knowledge, the following description can not be separated;
1. The centrifugal pump runs normally, the work efficiency is good, what teaching content does the development include?
Pressure, steady flow, outlet pressure to meet the needs of normal production, or more than 90% of the nameplate capacity.
Lubrication, cooling control system can be smooth, oil ring, bearing box, liquid level pipe and other complete and easy to use. The selection of lubricating oil meets the national regulations, and the bearing temperature meets the enterprise standard.
Stable operation, no noise, shaft string and vibration meet the standard.
The leakage of shaft seal reaches the standard.
2. What are the functions of the lubricating oil (grease)?
The functions of lubrication system include cooling technology, flushing, sealing structure, vibration reduction, protection and unloading.
3. Does it need to be filtered for three times?
Grade I: between the original barrel and the fixed barrel for lubricating oil;
Second level: fixed between oil barrel and oil pot;
Third floor: between the tank and the filling point.
Lubricant (grease) for pump lubrication in workshop?
Pumps 1350 / 1, 2 use calcium based lubricants. Pump 1146 uses 20 × 10 ~ 3 or 30 × 10 ~ 3 machine oil. The rest of the pumps use 46% machine oil.
5. What is the "12th Five Year Plan" of equipment lubrication?
Fixed point: add oil according to regulations;
Timing: according to the scheduled time of lubricating fuel, and regularly change the oil;
Quantitative: quantitative development and refueling according to consumption;
Qualitative: choose different lubricants according to the model, and keep the oil of acceptable quality;
Fixed person: we must have a special person responsible for every refueling part in China.
