After the correct installation of fire pumps, but also the proper operation of fire pumps, fire pumps to ensure the normal operation can also ensure the safety of life of the operator. Then Xiaobian and you introduce XBD-L single-stage vertical fire pump start-up, operation and parking operation precautions. XBD-L single-stage vertical fire pump First, XBD-L single-stage vertical fire pump start 1.XBD-L single-stage fire vertical pump for a suction occasion, that is, when the import is negative pressure, The road for irrigation or vacuum pump water, so that the water filled the entire pump and import pipelines, pay attention to the import pipeline must be sealed, there should be no leakage phenomenon. (Do not start without water before starting, you must first water, after the start) 2. Close the outlet pipe gate valve and pressure gauge cock to reduce the starting current. 3. Rotate the rotor by hand a few turns to lubricate the bearing and check whether the impeller and the seal ring in the pump are rubbing against each other. If the rotor does not move, it should not be started until the cause of the fault is found out. 4. Start the test, the motor should be turned and the arrow on the pump point to the same, open the meter cock. 5. When the rotor reaches normal operation, the pressure gauge shows pressure, gradually open the outlet gate valve, adjust to the desired conditions. Second, XBD-L single-stage vertical fire pump operation 1.XBD vertical single-stage fire pump is mainly used for fire-fighting system pipeline pressurized water supply, transport, you must observe the instrument readings, try to pump the flow rate in the nameplate Work near, to prevent large-flow operation. 2. Regularly check the motor current value should not exceed the rated current. 3 fire pump bearing temperature shall not exceed 75 ℃, and may not exceed the outside temperature of 35 ℃. 4. The pump pack should be loosened at the beginning of operation Gland, when the expansion of graphite or filler is fully expanded and then adjusted to the appropriate level. 5. Wear parts too large wear and tear should be promptly replaced. 6. Found anomalies, stop immediately check the reasons. Third, XBD-L single-stage vertical fire pump down 1. Close the gate valve on the outlet pipe, turn off the vacuum gauge cock. 2. Stop the motor, then close the pressure gauge cock. 3. If the winter cold season, the pump liquid should be exhausted, so as to avoid cracking. 4. Long-term stop using the pump should be disassembled, cleaned and oiled, safekeeping.
