Centrifugal pump related basic knowledge
1. What is the main working principle of the centrifugal pump?
The motor drives the impeller to rotate at high speed, so that the liquid produces centrifugal force, due to the role of centrifugal force, the liquid is thrown into the side flow channel to discharge the pump, or into the next level of the impeller, so that the pressure at the inlet of the impeller is reduced, and the pressure difference is formed in the suction of the liquid suction pump, because the centrifugal pump keeps rotating, the liquid is constantly sucked or discharged.
2, What is the role of lubricating oil (fat)?
Lubricating cooling function, flushing function, sealing function, damping function, protection function, unloading function.
3. Which three levels of filtration should the lubricating oil go through before use?
The first level: between the original lubricating oil barrel and the fixed barrel;
The second level: fixed between the oil drum and the oil can;
Level 3: Between the oil pot and the refueling point.
4, what is equipment lubrication "five fixed"?
Fixed point: refueling according to the specified point;
Timing: according to the specified time to lubricate the parts, and regularly change the oil;
Quantitative: according to consumption quantitative refueling;
Quality: Choose different lubricating oil according to different models, and keep the quality of oil qualified;
Person: There must be a special person responsible for each refueling part.
