Mechanical Seal Akman's Blog

First, before the start of preparatory work and notes
1, a comprehensive inspection mechanical seals and ancillary equipment and pipeline installation is complete, compliance with technical requirements.
2, mechanical seals start before the static pressure test, check whether the mechanical seal leakage. If the leak more reason should be investigated to eliminate. If still ineffective, should be demolished and re-install checks. Hydrostatic test pressure normally used 2 to 3 kg / square centimeter.
3, according to the pump rotation to the disk car, check for light evenly. Such as the car difficult or fixed disk, the assembly should check whether the size of the error, the installation is reasonable.
Second, installation and decommissioning
1, shall remain sealed before the start of fluid-filled cavity. Solidification of the medium for transmission, the application of steam to the sealed chamber heated to medium melt. Must be set before the start of vehicle to prevent sudden start caused by soft ring fragmentation.
2, for use outside the seal pump mechanical seal oil system, seal oil system should start. After stopping the last stop seal oil system.
3, heat pumps can not immediately stop after shutdown seal chamber and seal oil cooling water, wait until the seal oil temperature dropped to 80 degrees below office only when the cooling water can be stopped, so as not to damage the sealing parts.
3, operation
1, the pump starts if minor leakage should be observed for some time. Such as 4 hours continuous operation, leakage is still not reduced, they should check the pump stops.
2, the pump operating pressure should be steady, the pressure fluctuation is less than 1 kg / square centimeter.
3, pump operation, it should avoid taking the time to the phenomenon, so as to avoid friction and sealing the sealing surface damage.
4, the situation should always check the seal. Operation, when the leakage exceeds the standard, heavy oil is not more than 5 drops / min, light oil is not greater than 10 / min, such as 2-3 days, still no signs of improvement, it should stop the pump bolt inspection seal.
