Coal mine with wear-resisting multistage pump pipe road installation schematic and installation considerations

coal mine with wear-resisting multistage pump pipe road installation note:

1. Installing a coal mine with wear-resisting multistage water pump suction culvert, segment level, or curling.

       2. Inlet pipe bend more for the way.

       3. Coal mine with wear-resisting multistage pump inlet attached directly to the elbow.

       4. Equipped with a bottom valve inlet pipe of the most in the next section is not vertical.

       5. Coal mine with wear-resisting multistage pump inlet pipe inlet position is not right.

       6. Coal mine with wear-resisting multistage pump outlet pipe mouth more than normal water level in the pool.

and fastening on the foundation after grouting pump, pump under the condition of not affected by external force to the connecting flange and pipe flange, the force of the connecting flange bolts can't lead.

the pipe support ( Additional) Should avoid the vibration of the pipeline system, should reduce piping to the compelling force of the pump.

in order to prevent the damage of the pump, the pump pipe to the piping system before cleaning jobs.

piping installation, attention should be paid to the following items:

a) Use of the specifications of the line and the length should be appropriate, and has enough bearing capacity, minimize the turning of the piping and accessories;

      b） suction pipe should be short and straight, pipe diameter should be greater than or equal to the diameter of the inlet of the pump, pump suction pipe bending radius should be great. If using cone tube, using eccentric taper tube, in order to avoid heavy gas and produce cavitation.

1, the installation of pump base plane application level leveling. After foundation of cement solidification, should check whether the base and anchor bolt hole is loose;

2, motor, pump and base after assembly, should check the pump shaft and motor shaft concentricity, guarantee that the two axis at online;

3, motor and pump assembly, the water pump coupling end should be pulled out, ensure the pump and motor end of the two coupling axial clearance value;

4 and pump can only carry their own internal force, unable to bear any external forces. suction pipe and the pressure pipeline should have their own support, in order to avoid the pump pressure.
