(2) try to control the self-priming pump flow and lift the range indicated on the plate to ensure that the self-priming pump at the highest efficiency point of operation, in order to get the maximum energy-saving effect.
(3) self-priming pump during operation, the bearing temperature can not exceed the ambient temperature 35C, the maximum temperature shall not exceed 80C.
(4) If there is an abnormal sound of self-priming pump, it should stop immediately to check the reason.
(5) sewage pump to stop using, first close the gate valve, pressure gauge, and then stop the motor.
(6) self-priming sewage pump in the long time do not need to use and in the winter season, after parking, you need to unscrew the lower part of the drain plug to drain the media to the net. Prevent cracking. (If the sewage please clean the pump chamber with water)
(7) Seriously listen to the motor running sound is abnormal, due to run-time engine room noise can be greater by means of a screwdriver or aids such as listening sticks, stick pro-motor at both ends to listen, if you often hear, not only to find the motor and its drag Bad vibration of moving equipment, even the number of internal bearing oil can be judged, so that the timely addition of bearing oil, or replace the bearings and other appropriate measures to deal with, to avoid motor bearings lack of oil dry and blocked, take the outer circle, Burn out.
Second, Haitan pump troubleshooting a, pump head is not enough 1, stainless steel self-priming pump impeller corrosive liquid used for serious corrosion? Change the impeller 2, the pump performance can not meet the design requirements? In order to meet the design requirements of Bo Yu pump 3, lack of speed? Check the current, speed recovery 4, semi-open impeller and pump cover clearance is too large? Reduce the gap b, the pump vibration serious 1, pump and motor shaft is not the same? Adjust, align the pump and motor shaft 2, the pump shaft bending? Remove the straightening or replacement 3, impeller imbalance? Remove the balance to find c, pump bearing overheating 1, lubricating oil (fat) is not enough? Add grease (grease) to the required standard 2, pump and motor shaft is not the same? Adjust, align the pump and the motor shaft 3, bearing damage? New Bo Yu pump bearings Third, Haitan pump mechanical seal leakage 1, the lack of spring pressure? Re-adjust the amount of spring compression or change the spring 2, change or static ring end corrosion, wear or scratches? Repair or replace the bad ring static ring 3, the fixing screw is loose, the spring loses effect? Tighten the screws or re-adjust the spring 4, moving ring seal assembly ramp or corrosion deformation? Reinstall or replace Bo Yu pump ring 5, static assembly skew? Heavy Bo Yu pump with static 6, sleeve machining accuracy and finish is not enough, affecting the axial movement of the moving ring? Change the machining accuracy of the sleeve 7, Impurities, foreign bodies or medium crystallization affect the axial movement of the moving ring or support in the dynamic and static end of the ring? Elimination of impurities, foreign bodies and crystallization, thoroughly clean the sealing element Fourth, the sea pump seal leak serious 1, the packing pressure is too loose? Tight packing gland to an appropriate level 2, packing device is not good? Adjust the filler take the mouth, so that a certain angle is not in a direction of staggering 3, the filler of different sizes or serious wear? Replacement of a unified model Bo Yu filler 4, the poor quality of the filler seal is not good? Replacement of asbestos packing to meet the requirements 5, sleeve wear too much? Replace the sleeve five, Haitan pump motor overheating 1, the use of (flow, head) than the pump design requirements? Select the appropriate type of motor spectrum 2, the proportion of more than the pump motor configuration motor? Configure the appropriate Bo Yu pump motor 3, packing gland pressure is too tight or mechanical seal spring is too tight? Re-adjust the gland or mechanical seal spring compression 4, the pump assembly quality is poor, there is friction or motor and the pump shaft is not the same? Check assembly quality, eliminate assembly problems
