Engineering mechanical seal Remove the note:

In the installation and disassembly of mechanical seal carefully, prohibited the use of hammer and chisel, so as not to damage the sealing element. If not remove fouling, should be cleaned after removing.

If both ends in the pump with mechanical seal, take care of each other in the assembly, the disassembly process, prevent the care for this and lose that.

On the operation of mechanical seal, the sealing gland where there is loose move, then the dynamic and static ring parts must be replaced, should not continue to use re tightening. Because after the loosening of friction will change the original orbit, the contact surface of the seal is very vulnerable to damage.

Engineering mechanical seal Ready to start work before:

Check the mechanical seal, and ancillary equipment and pipeline installation is complete, compliance with technical requirements.

Mechanical seal before the start of the hydrostatic test, check the mechanical seal leaks. If the leakage is more, should identify the reasons to eliminate. If still valid, you should remove and reinstall the check. The general static pressure test pressure of 2~3 kg / cm2.

According to the pump rotate to turning check whether a uniform. Such as turning demanding or not move, it should check whether the assembly size error installation is reasonable.

Engineering mechanical seal Install and outage:

Before the start should be kept sealed cavity filled with liquid. To deliver solidified medium, the application of steam seal chamber heating melt medium. Before the start must be turning in order to prevent the sudden start caused by soft ring fragmentation.

For the use of pump oil sealing system of the mechanical seal, the sealing oil system should be the first to start. Finally stop the seal oil system of parking.

Can't stop cooling water sealed oil chamber and seal oil pump after the shutdown, should be the end seal oil temperature dropped to 80 degrees below, can stop the cooling water, so as not to damage the sealing parts.
