Description

Technical Parameters

Brief Introduction

After being successful in non-load test run of this IECEX explosion proof motor, continuously load and implement loaded start test run.

During loaded running period of the motor, pay attention to running speed of the motor; specifically at high speed, keep rotation speed of the motor within allowable max rotation speed.

When the motor is stopped for more than one month, environment of the motor is relatively wet and often has relatively high temperature change; it shall electrify damp-proof heating device of the motor frequently or continuously, an inspect at regular time so that the damp-proof heater is under a normal working state.

All naked metals shall be coated with anti-rust oil on surfaces thereof.

All control or driving devices of the motor shall have warning signs which include related situations of devices and work before starting.
