Application of hydraulic pump station in railway

Hydraulic pump station in the use of more and more extensive! At present, our hydraulic pump station has been applied to the railway welding track! Next small make up to introduce for you!

1. Place the heater on two guide rails of the press.

2. Lock the heater body and adjust the heating height so that the heater burner is consistent with the clearance around the rail, the heater fire hole plane should be consistent with the weld, and there should be enough swing range from side to side.

3. At this time, start the hydraulic pump station, pre-top the rail to start cooling hydraulic pump station and gas channel control box, adjust the fuel gas, and ignite the heater.

4. Swing the heater to heat the rail uniformly, and when the rail is hot to the plastic state, increase the pressure of the hydraulic pump station for top forging. After the top forging is a certain distance away, the heater will shut off and be removed.

5. After welding, loosen the rail bottom bolts, rail top bolts and inclined iron, and dismantle the press.

6. Install tempering rack and heater for tempering hydraulic pump station when the temperature of welding rail head is cooled below 400 ° C.

7. Polish the welding head
