1.1 pumps can only be allowed to operate within the specified parameters;
1.2 The pump is not allowed to operate when the discharge valve is closed or closed to a very small opening, otherwise it will cause the pump to heat up and reduce its life. If the pump is installed in a parallel system, each pump must run under certain parameters Ensure the pump flow;
1.3 pump can not close the suction valve to run, otherwise dry pump occurs, resulting in pump parts damaged;
1.4 pump delivery medium can not contain air or gas, otherwise it will make the pump flow and lift can not be accurately measured at the same time will produce grinding damaged parts;
1.5 This type of pump can not convey the material with particles, otherwise it will reduce the pump efficiency and parts life;
1.6 Kai pump before the pump should be checked before the warships.
2, check before starting the pump
2.1 before starting the pump, check all the bolts, pipe and lead connections are fastened;
2.2 to check all the instruments, valves and instruments are routine;
2.3 Check the oil ring position, the oil level gauge is normal;
2.4 Check the motor steering is correct.
3, the pump started
3.1 pump start matters needing attention
a, the pump medium high temperature (<160 ℃);
b, observe the start pressure gauge and switch instructions to adjust;
c. After the pump starts, the discharge valve can not be closed or close for a long time, otherwise it will overheat the liquid in the pump.
3.2 Kai pump step
a, first before starting (according to the above steps);
b, open the pump suction valve and water seal water valve;
c, close the discharge pipe, so that the pump full of liquid;
d, start the motor , then open the valve discharge pipe.
4, pump operation check After the pump is running, it should be the city according to 2.2 procedures at regular intervals to check the instrument, in order to determine the pump] work is normal, and to check the pump speed, in addition, monitor pump flow, lift, Temperature and lubrication conditions. Pump in the event of failure, should stop the pump, and refer to the troubleshooting table for maintenance.
5, stop the pump
5.1 The pump discharge valve fire to a minimum flow, but never allowed to close the pump suction valve;
5.2 Turn off the motor;
5.3 Close the pump discharge valve;
5.4 When the pump is stopped and then shut down the pump suction valve.
