2GC twin screw pump

1. Mounting the pump and prime mover on the sufficient strength pedestal that can prevent the component damaged by vibration and ensure the pump work regularly.

2. Requirements for the connection of the pump and power should not lower than government standard.

3. The general working type: facing input driving screw, the input is in the right, the outlet upside and the rotating direction is right rotation. Please advise requirements when place order if other type is necessary. The vertical pump is same structure, only main screw vertical when setting.

4. Necessary to add filter, and the filter’s specification is 20mesh. The filter flow area should be more than 4 times of the input area of the pump.

5. The size of pipe must be no difference with that of pump input and output mouth, otherwise, it will effect pump using performance.

6. Clear all pipe and filter before the first time using, to make sure pump work normally.

7. Before pump starting up, all valve on pipe must be open. After normal working, it can be adjusted according to practical need.

8. After pump starting up, notice the pump vacuum value, if no vacuum after 1 minute, the pump should be stopped and checked.

9. When using pump to sweep cabin, race rotation ran not to exceed 3 minutes, in case of the damage of seal.

10. The gear oil should use 180# middle load gear oil. Check oil level of gear box frequently to make sure pump working normally. When working normally, the temperature of oil in gear box do not exceed 70C. When pump work for long time. The temperature do not exceed 80C.

11. Check lubricating grease for gear frequently and add oil regularly.

12. Closed screw Leaking frame pump: leak in the downside of the right and left shaft sealing frame; if the sealing is damage and leakage happens, the other pipes cannot be closed to avoid the bearing damaged.

13. The pump’s flow rate is too large and its pressure is too high, according to different conditions, bearing and gear box is equipped with the water circulating to cool the temperature. The flow of circulating cooling water is about 2m3/h.

14. When transporting high viscosity media, it should use the pump equipped with heating system.
