Matters needing attention in the operation of the plate heat exchanger (1) plate heat exchanger was driving may have a slightly leaking phenomenon, don't need to adjust, will soon be gone. If run 1 & ndash; There are still micro leakage after 2 h, using a wrench to tighten the clamping bolt, a little to eliminate leakage. (2) the medium inside the plate heat exchanger operation pressure drop exceeds allowable values, should be timely find the reason, take measures to deal with. If the pressure drop increases suddenly, general is population have sundry jam or severe scarring. Shall, first of all, to carry on the back flush, such as the effect is not obvious, should arrange maintenance cleaning in hot plate. (3) found that there are two kinds of medium to collude with each other ( By analyzing the parts of the medium and pressure change situation to judge) , especially for flammable and explosive medium, should stop immediately, check and change the hole or crack plate heat exchanger plate. (4) strict control of temperature and pressure shall not exceed the allowable values, otherwise it will accelerate the aging of sealing gasket, sealing gasket and plate heat exchanger from local media and rushed out of the plate of serious leakage situation (such as Especially not sealing gasket groove umbrella plate heat exchanger) 。 (5) exceeds allowable values, pressure drop of filter should be back flush, should be replaced when the effect is not obvious. To remove the filter apart with steam or compressed air cleaning filter. 6 inspection found that the plate heat exchanger heat transfer plate bundle leakage should be ready for when, in order to open it immediately after the equipment found to damage to the plate and sealing gaskets, change into new heat transfer plate and sealing gasket. All landowners for plate heat exchanger in the operation of the media, under the condition of the pressure, do not allow the fastening clamping bolt. Was fastened heat exchange plate clamping bolt and nut, should strictly control the distance between the two end plate plate beam, otherwise easy to damage in hot plate or sealing gasket. Pet-name ruby slide plate heat exchanger activities the sprocket should be lubricated periodically to prevent rust, to ensure the removal of flexible use. Attending plate heat exchanger began to run, such as uneven and found that heat exchanger, should check whether there clean air, channel blockage etc. , and take the corresponding effective measures to deal with.
