01 The main working principle of centrifugal pump
The motor drives the impeller to rotate at a high speed, causing the liquid to generate centrifugal force. Due to the centrifugal force, the liquid is thrown into the side channel and discharged out of the pump, or enters the next impeller, so that the pressure at the inlet of the impeller is reduced, and the pressure acting on the suction liquid is formed. The pressure difference acts on the liquid suction pump. Due to the continuous rotation of the centrifugal pump, the liquid is continuously sucked or discharged.
02 Lubricating oil (grease) function
Lubrication and cooling effect, flushing effect, sealing effect, damping effect, protection effect and unloading effect.
03 Lubricating grease needs to go through three-stage filtration before use
1: between the original lubricating oil barrel and the fixed barrel;
2: between fixed oil drum and oil pot;
3: between the oil pot and the refueling point.
04 Equipment lubrication five
Fixed point: refuel at the specified point;
Timing: according to the provisions of the time to the lubrication part of the oil, and regular oil change;
Quantification: Refueling is quantified according to consumption;
Quality determination: choose different lubricants according to different models, and keep the quality of the oil qualified;
Fixed person: each refueling part must have a special person in charge.
