XBD Fire Pump Unit Startup, Operation, and Shutdown Troubleshooting

Start 1, the pump set for a suction process, that is, the import is negative pressure, the pipeline should be filled with water or diverted with a vacuum pump, so that the water fills the entire pump and the inlet pipe. Note that the pump pipe line must be sealed. There is a leak. (Before starting, it is forbidden to start without water and advanced water must be used to start)

2. Close the gate valve and pressure on the outlet pipe to reduce the starting current.

3, Turn the rotor by hand several times to lubricate the bearing and check if there is rubbing between the impeller in the pump and the bad operation of the seal. If it does not move, it should not be started until the cause of the fault is found.

4, start the trial, the motor steering should be consistent with the arrow on the pump point. Open the rotation base.

5. When the rotor reaches normal operation, the pressure gauge shows pressure. Open the outlet gate gradually and adjust to the required working conditions.

Key words: XBD fire pump operation 1, XBD fire pump pump group is in operation. It must pay attention to observe the meter reading. Try to make the pump work near the flow head specified in the nameplate. Prevent large-flow operation.

2, the time to check the motor current value should not exceed the rated current.

3, the bearing group of the pump shall not exceed 75 Â°C, and shall not exceed 35 Â°C outside temperature.

4, the pump group should be relaxed at the beginning of the operation of the material pressure cap. When the expansion of graphite or filler completely expanded and then adjusted to a suitable degree.

5, The excessive wear of the easy-to-wear parts should be replaced 6 in time, and an abnormal phenomenon is found. Check the reason immediately after shutdown.

XBD Fire Pump Stop 1. Close the gate valve on the outlet pipe. Close the vacuum watch tap.

2. Stop the motor and close the pressure tap.

3, If there is a cold season in winter, the liquid in the pump should be drained to prevent freezing.

4. Discontinue use for a long period of time. The pump should be disassembled, cleaned, and properly stored.

Z408 Cast Iron Welding Electrodes

Description:

Z408 Cast Iron Welding Electrodes is a graphitic(with strong reducing) type coating with Nickel/Ferro core welding electrode for cast iron. It has features as follows: high toughness, excellent plasticity, low linear expansion coefficient, etc, Both AC and DC can be applied in welding.

Applications:

Z408 CAST IRON WELDING ELECTRODES is used for repairing important and high toughness parts made of gray cast iron and nodular iron, such as cylinder head, motor stand, gear wheel, etc.

Attention:

A. Welding Electrodes must be baked for 1 hour at the temperature of 150â„ƒ before welding.

B. Small current is best to be adopted.
