Measure the amount of leakage in accordance with the rules of HG2099. The leakage rate of the mechanical seal under the pressure of the equivalent of the volume of liquid, the rules are: shaft diameter greater than 80mm, the leakage is not greater than 10mL / h; shaft diameter of not more than 80mm, the leakage is not greater than 8mL / h.
Determination of the amount of leakage in accordance with the rules of HG2099. The diameter of not more than 80mm, the leakage is not greater than 8mL / h Single-ended mechanical seal only to do the qualitative view of the leak to the naked eye investigation no significant bubbles as qualified.
When the sealed medium is liquid, the uniform leakage rule is the same as above.
The amount of wear and tear to meet the kettle mechanical seal application period of the request, under normal circumstances, work 100h, soft material seal ring wear is not greater than 0.03mm.
In the selection of reasonable, accurate use of the device, the sealed medium is neutral, weak corrosion of other or liquid, the mechanical seal of the application period is usually 8000h; sealed medium is more corrosive or volatile gas, The mechanical seal of the use of the cycle is usually 4000h, special circumstances are not subject to this limit.
