Common failures and solutions of plate heat exchangers
Familiar with the common faults and solutions of the plate heat exchanger, not only can effectively help oneself better control the heat exchanger equipment, but also can prevent the adverse effects caused by the failure in time when the plate heat exchanger fails, thereby Avoid aggravating the damage of the heat exchanger. So let's talk about some common faults and solutions of the device below, come and have a look.
A. Leakage between the plates of the plate heat exchanger
1. Excessive clamping of the heat exchanger plate group, causing damage to the heat exchanger gasket groove; replace single and multi-piece heat exchanger plates.
2. The heat exchanger gasket is misplaced; re-adhesively install the heat exchanger gasket.
3. The heat exchanger plate group is over-clamped, and the support beam is recessed, which causes the heat exchanger plate to be twisted; replace the heat exchanger plate.
4. Not fully clamped; re-clamp.
5. The heat exchanger plates are placed upside down; the heat exchanger plates are reversed.
6. The slot hole of the heat exchanger gasket is double-sealed and corroded; replace the corroded heat exchanger plate and gasket.
7. The heat exchanger gasket is cracked or worn, aging, or corroded; replace the heat exchanger gasket.
B. Between the heat exchanger plate of the plate heat exchanger and the frame or outside the frame
1. There are crevices (corrosion) at the joints of the first plate holes of the heat exchanger; replace the connecting parts.
2. The joints are sealed in dislocation; fix the sealing ring.
3. The pipe is forced to twist the joint part; hold up the pipe with a support.
4. The sealing gasket of the first plate of the heat exchanger is damaged or corroded; the sealing gasket of the heat exchanger.
5. There is a hole in the first plate of the heat exchanger (corrosion); change the end piece.
In general, the cause of the failure of the plate heat exchanger is nothing more than the installation quality is not up to the standard, the operation method is incorrect, the later maintenance, the overhaul operation is not in place, etc., so it is necessary to hope that the plate heat exchanger equipment does not occur Failure, we must do a good job in these aspects, although it cannot be said that the failure problem will not occur at all, but at least to a certain extent, the failure rate of the heat exchange equipment can be reduced, thereby extending its service life.
