Disassemble: Check the wearing parts, such as rolling bearings, mechanical seals, impeller, etc., if damaged should be promptly replaced.
Pressure test: disassemble repair or replacement of the seal must be sealed after the motor chamber and air pressure test, test pressure of 0.2Mpa, which lasted 3 minutes without leakage and sweating phenomenon.
