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 °C, and shall not exceed 35 °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.
Galvanized steel sheet is a kind of welded steel sheet with hot-dip or electro galvanized coating on its surface, which is widely used in construction, household appliances, vehicles and ships, container manufacturing, mechanical and electrical industry, etc. Hot dip galvanized steel sheet (SGCC): galvanized, bright white, small zinc flower (difficult to see), large zinc flower can obviously see hexagonal flower block. Hot dip galvanized steel sheet (SGCC) has an advantage over electro galvanized steel sheet (SECC). The bending and section of SECC are easy to rust, and the corrosion resistance of SGCC is much better under the same conditions.
Main characteristics: corrosion resistance, painting property, formability and spot welding property. It is widely used, mainly used for small household electrical appliances which need good appearance. According to zinc classification: the size of zinc flower and the thickness of zinc layer can explain the quality of zinc plating, the smaller the thicker the better. Manufacturers can also increase fingerprint resistant processing. Another is that it can be distinguished by its coating. For example, Z12 represents the total amount of double-sided coating 120g / mm.
