[FB, AFB stainless steel corrosion-resistant centrifugal pump] start, run and stop: 

 1, before starting preparation 
 ⑴ start before you put the pump and on-site clean up. 
 (2) check the bracket amount (the amount of lubricating oil and the oil surface in the oil level gauge centerline is about 2mm) Oil level gauge whether intact. 
 ⑶ missed check the prime mover, steering, coupling before and after pump turn arrow on, take a good coupling. 
 (4) After install the mechanical seal can be easily turned by hand the shaft should be no grazing, and coupling guard installed. 
 ⑸ the pump suction on the case, before starting the irrigation pump or vacuum; pump intrusion case, before starting the application of transmission fluid to the pump filled, get rid of empty the pump, it will spit out the tube valve closed. 
 ⑹ starting to check whether the foundation bolts loose. The gland is skew, as well as oil and cooling water supply. 
 2, starting 
 "⑴ Close the import and export of pressure (or vacuum) meter and the water valve (if the bypass pipe should be closed at this time.) Starter motor (best to jog, make sure the pump is turned to the right after started running.) , and then open the outlet pressure (or vacuum) dollars, when the pump reaches normal speed, and the instrument that the corresponding pressure, and then slowly open the water valve to adjust to the desired conditions. In spit pipeline shut down, the pump work, not more than three minutes. 
 ⑵ starting process to always pay attention to the original motive power readings and pump vibration, the vibration number of not more than 0.06 mm, a measurement site is bearing. 
 (3) of seals: mechanical seal should be no leakage, fever phenomenon, packing should be a continuous trickle state. 
 3, run 
 Heat the ⑴ often check the pump and motor (bearing temperature rise should not exceed 75 ° C) and oil gauge oil supply situation. (Generally every run for 1500 hours, all the replacement of oil once). 
 ⑵ can not use the suction valve to regulate flow, to avoid cavitation. 
 ⑶ pump should not be in continuous operation below 30% of design flow, if you have the conditions of continuous operation should be installed at the exit of the bypass tube, discharge excess flow. 
 (4) pay attention to pump operation without noise, such as abnormal, it is timely to eliminate or stop and check. 
 4, stop 
 ⑴ slowly close the outlet pipe valve (if pump intrusion case, but also turn off the suction line of the valve), and close the switch of a variety of instruments. 
 ⑵ cut off the power. 
 ⑶ sealed with external priming, but also to close the priming valve. 
 ⑷ If the ambient temperature is below the liquid freezing point, to put the net pump the liquid to prevent the cracking. 
 ⑸ If long-stay parking unused, in addition to pump corrosive liquids put a net outside, all parts should be removed to clean, especially in the sealed chamber. It is best to re-installed the pump removed after cleaning, in addition to the rust treatment of oiled and closed pump inlet and outlet, should be regularly checked. 

 [FB, AFB stainless steel corrosion-resistant centrifugal pump] the use of mechanical seals Note: 

 This type pump according to the different conditions of use to install various forms of mechanical seal (such as built-in single end face balanced and non-balanced type, double-end balance of type and non-flat balance-type, externally mounted mechanical seal, etc..) According to the choice of seal type of different from its use and precautions are also different. Below only to mention a few general should pay attention. 
 1, due to the mechanical seal is generally clean, no suspension used in granular media, the newly installed piping systems and reservoir filling, should be carefully rinsed to prevent solid impurities into the mechanical seal faces leaving the seal failure. 
 2, in crystallize media, use of mechanical seals should be noted that often wash. To mechanical seal crystallization cleaned before re-start after parking. 
 3, the demolition of mechanical seals should be carefully, and not to hand hammer, iron and other percussion, so as not to undermine the move, stationary ring sealing surface. 
 4, if there is dirt demolition is not down, we should try to remove dirt, rinse and then be demolished, so as not to damage the sealing elements. 
 The mechanical seal should check whether all the sealing elements failure or damage, if any should be repaired or replaced. 
 6, should be strictly check the relative friction ring and stationary ring sealing surface does not allow any minor defects such as scratches, bumps. All the other components, including the pump body, impeller, sealed chamber rinse should be before the assembly, especially in dynamic, static ring the temple face, use clean, soft cloth or cotton, carefully wipe clean, and then coated with a layer of clean grease or oil. 
 7, the assembly should pay attention to eliminate bias, tighten the screws should be evenly tightened to avoid deflection, so that the seal failure. 
 8, the right to adjust compression spring, the pump is installed to the hand pulling the rotor should be felt seal the spring has some amount of compression, but also light and flexible to rotate without clenched feeling. If you feel tight or plate does not move, should be an appropriate tone loose. 
 9, external flushing mechanical seals, the starter should be preceded by open fluid, the seal cavity filled with sealing liquid. When stopping, stop the pump, off seal flushing fluid.
