Steam trap installation method Whether the trap is properly installed has a direct impact on the normal operation of the trap and the production efficiency of the equipment. The installation of the trap must be in accordance with the formal installation requirements in order to achieve optimum efficiency of the trap and equipment.
1. Before installing the trap, be sure to purge the pipeline with pressurized steam to remove debris from the pipeline.
2. A filter should be installed in front of the trap to ensure that the trap is not blocked by the pipeline and clean the filter regularly.
3. Install the valve before and after the trap to facilitate the repair of the trap at any time.
4. The condensate flow direction should be consistent with the trap installation arrow mark.
5, the trap should be installed at the lowest point of the equipment outlet, timely discharge of condensate, to avoid steam resistance of the pipeline.
6. If the trap is not installed at the lowest position of the equipment, add a backwater bend (condensation water lifting joint) at the lowest position of the water outlet to raise the condensed water level and then install the steam trap to avoid steam resistance.
7. The outlet pipe of the trap should not be immersed in water. (If immersed in water, drill a hole in the bend to break the vacuum and prevent the sand from sucking back.)
8. Mechanical traps should be installed horizontally.
9. Steam traps should not be installed in series.
10. Each device should be fitted with a trap.
11. Before the thermostatic trap, more than one meter of non-insulated subcooling pipe is required. Other forms of trap should be as close as possible to the equipment.
12. When the drum type drying (with siphon type) equipment uses the steam trap, please specify: use the steam trap with anti-steam resistance device to avoid the steam lock of the equipment.
13. If there is condensate recovery after the trap, the trap outlet pipe should be connected to the manifold from the top of the recovery manifold to reduce back pressure and prevent backflow.
14. If there is condensed water recovery after the trap, the pipelines with different pressure levels should be recycled separately.
15. After the trap, the condensate recovery manifold cannot climb the slope, which will increase the back pressure of the trap.
16. Install a check valve before the condensate from the trap enters the recovery manifold to prevent condensate from flowing back.
17. Install a trap on the steam line. The main pipe should be provided with a condensate collecting well close to the radius of the main pipe, and then piped to the trap.
18, mechanical traps are not used for a long time, you must remove the drain screw to drain the water inside to prevent freezing.
19, found that the steam trap running steam, it is necessary to timely discharge and clean the filter, according to the actual use of the situation to check, in case of failure to repair at any time. At least one inspection per year is required to remove impurities.
The trap is considered as a small part in the whole steam system, but it has a great influence on the system operation and economic operation. Therefore, the maintenance and overhaul of the trap is also crucial, and only the importance of the trap in production is fully paid attention to. Diligent maintenance, so that the trap is often in good working condition, in order to ensure the best energy-saving effect and improve economic efficiency.
