HRL Series 8.2 Inspection and Cleaning
Cleaning of the facility water system (For water-cooled type)
Clean the customer's facility water system and replace facility water.
Facility water quality must satisfy the criteria specified in “Table 8.1-1
Quality criteria for clean water (tap water)”
8.2.4 Inspection every 6 months
Check for water leakage from pump (For option T3 [CH2 High-Pressure Pump
Mounted])
Remove the panels and check the pump for excessive leakage. If the
leakage is found, replace the mechanical seal.
Fig. 8-3 Leak check
If there is foreign matter accumulated or clogging in the facility water
system, pressure loss increases with less flow rate, and it may
damage the screen mesh.
Leakage from the mechanical seal
It is impossible to prevent the leakage from the mechanical seal completely because
of its structure. Although the leakage is described as 3cc/hr or less.
The recommend life time of the mechanical seal before needing replacement is 6000
to 8000 hours (usually 1 year)
