The failure of the Steam Trap will directly affect the action of the switching valve and the regulating valve. Common failures include the Steam Trap not operating, which should be checked from the following aspects:
(1) If the connection head of the Steam Trap is loose or the thread ends fall off, the Steam Trap valve must not be powered, and the thread ends can be tightened.
(2) If the Steam Trap coil is burned out, you can remove the wiring of the Steam Trap and measure it with a multimeter. If there is an open circuit, the Steam Trap coil is burned out.
The reason is that the coil is damp, causing poor insulation and magnetic leakage, causing excessive current in the coil and burning out. Therefore, rainwater must be prevented from entering the Steam Trap. In addition, if the spring is too hard, the reaction force is too large, the number of coil turns is too few, and the suction force is not enough, the coil may be burned. During emergency treatment, the manual button on the coil can be moved from the "0" position during normal operation to the "1" position to open the valve.
(3) The Steam Trap is stuck. The fitting gap between the
Slide Valve sleeve and the valve core of the Steam Trap is very small (less than 0.008mm). It is usually assembled in a single piece. When mechanical impurities are brought in or there is too little lubricating oil, it is easy to get stuck. The treatment method can be to insert a steel wire through the small hole in the head to make it bounce back. The fundamental solution is to dismantle the Steam Trap, take out the valve core and valve core sleeve, and clean it with CCI4 to make the valve core move flexibly in the valve sleeve. When disassembling, attention should be paid to the assembly sequence of each component and the position of external wiring to ensure correct reassembly and wiring. Also check whether the oil spray hole of the lubricator is blocked and whether the lubricating oil is sufficient.
(4) Air leakage. Air leakage will cause insufficient air pressure, making it difficult to open and close the forced valve. The reason is that the sealing gasket is damaged or the slide valve is worn, causing air leakage in several cavities.
When dealing with a Steam Trap failure in a switching system, you should choose an appropriate time to deal with it when the Steam Trap loses power. If the problem cannot be completed within a switching gap, the switching system can be suspended and the problem can be dealt with calmly.
