Boiler feed Pump Operation Precautions and Related Requirements

Boiler feed pump operation considerations and related requirements:
        1, the boiler pump test run before the inspection items are as follows:
        (1) refueling car: check the pump on the oil cup, to the hole within the oil, turbo coupling, turning should be flexible, no abnormal phenomenon;
        (2) check the anchor bolts should be no loosening;
(3) the lubricating parts are added lubricating oil, the need for cooling parts have been filled with cooling oil;
        (4) the instructions instrument, safety protection devices and electronic control devices should be sensitive, accurate and reliable;
        (5) The direction of the motor should be in accordance with the direction of the pump: Before connecting the battery, replace the connection plate (back wheel) to connect the screw, check the motor direction after power, turn the correct direction, and then connect to avoid reverse.
        (6) centrifugal pump must be filled with water and then start, should not be idle. Boiler water pump center, such as lower than the suction surface, you do not need irrigation, just put the pump air can be released. If the boiler water pump center is higher than the suction surface, should first open the suction pipe valve and vent, close the discharge pipe valve, to be vented with water, the speed is normal, then open the outlet pipe valve, and pump regulation To design conditions.
        (7) boiler water pump in the case of closing start, the running time should generally not exceed 2-3 minutes, such as the time is too long, the pump liquid heat, easy to cause accidents, it should be timely parking.
        2, the boiler pump test run when the motor temperature, boiler water pump operation, pressure gauge and vacuum table pointer values, interface tightness, etc. should meet the standard specification requirements, as follows:
        (1) operation should not have abnormal vibration and sound, the precision seal should not be leaked, fastening the connection parts can not be loose;
        (2) bearing temperature rise must comply with the provisions of the equipment manual;
        (3) boiler water pump safety protection box electronic control devices and parts of the instrument to be sensitive, reliable and accurate;
        (4) Boiler pump under the design of the continuous test run time should not be less than 2h;
        (5) the temperature of the shaft seal filler should be normal, without special requirements in the case of ordinary filler leakage shall not be greater than 35-60ml / h;
        (6) The motor current and power should not exceed the rated value.
        3, boiler water pump should stop running after the following requirements:
        First close the pump at the exit of the valve, until the pump cooling and then turn off the auxiliary system of the valve, and then cut off the power to stop the pump;click this website：Dragon-pump.com
       Should be put away the pump to accumulate the liquid to prevent corrosion.
