1. Do not install where backpressure can occur.

2. Notes: 1. Type of steam turbine: B - Backpressure turbine, C - Extraction condensation turbine.

3. Build a new backpressure turbine to pull one DN1600 burning sulfur blower, worked low-pressure steam is used for sale.

4. With a backpressure condition created , ball check seats firmly against ball check seat.

4. try its best to collect and create good sentences.

5. Eliminate source of excessive backpressure or water hammer in the system downstream of the device.

6. Use Watts No.601 to dampen out backpressure and No.15 to eliminate water hammer.

7. Check module construction shall include built - in limIt'stops to prevent disc wear due to backpressure.

8. It is demonstrated that a flashing jet is worn away into a cone shape and the jet extinct length decreases with the increasing of pressure decay ratio of injection pressure to backpressure.

9. This series is normally used in health hazard applications to protect against back siphonage and backpressure.

10. The flow pressure drop through the trap indicates an increase of backpressure of the exhaust system.

11. Series 957, 957N, 957Z are normally used in health hazard applications for protection against back siphonage or backpressure.

12. Several methods for regeneration control of diesel particulate trap are analyzed in this paper. Based on the analysis, the backpressure control method is selected for experimental study.

13. The 757 DCDA, 757 NDCDA be installed under continuous pressure and be subjected to backpressure and back siphonage.

14. Series 757, 757 N be installed under continuous pressure and be subjected to backpressure and back siphonage.
