Servicing and inspection
(1) Verify all fasteners and locating pins circumstances no matter whether they are loosening.
(2) Always examine whether the leakage phenomenon of the physique.
(3) Pay out interest to lubrication, amount of grease and noises when running,
decide no matter whether it operates underneath the necessary problems.
(four) CZPT & grease: The lubricant is for medium load industrial equipment oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash position ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop point ≥
190ºC). Exchange the lubricant and grease soon after very first 200 several hours running, and exchange
once again soon after a moth operating. Later on, replace the lubricant and grease in accordance to the
setting and lubricant (grease) top quality suggest a suitable substitution for 3
months.
(5) Always check the inlet air filter, clean or change the filter in time.
(six) Blower overload occasionally not immediately shown, so pay out consideration to
the consumption and exhaust stress, bearing temperature and the recent increase traits
of motor to figure out regardless of whether the blower performs typically
(seven) Just before disassembling the blower, the assembling relation and dimensions
should be recorded or calculated, make marks on factors to make sure the CZPT
requirements after assembling.
(eight) When newly machine or overhaul, the oil tank should be cleaned just before use
and suggest substitute all grease right after 8 hrs operating.
