Technical and safety briefings have been carried out, and safety work has been implemented. <br>The steps of the trial run of the motor and <br>the position where the trial run of the machine is required must be safely protected (fences, warning labels, and the debugger must wear a reflective vest); <br>the bolts of the coupling make the motor separate from the machinery (except that it cannot be removed or does not need to be removed) ). <br>The barring truck should be flexible and free of jamming; <br>the motor with a fixed rotation direction or the machine with a fixed direction must first test the phase sequence of the power supply, and the wiring is consistent with the phase sequence of the rotation direction; the <br>cabinet is powered, check the three-phase voltage, If it is normal, close the motor circuit power supply, start the motor, determine the direction of rotation of the motor, and observe the instantaneous operation; after the motor is normal, restart the motor <br>when it is completely stationary; when starting, measure the three-phase starting current. <br>The three-phase current should be balanced; <br>after normal operation, measure the no-load current of the motor and keep it balanced. The temperature rise, vibration, and noise of the motor should not exceed the specifications. The no-load operation of the motor is 2 hours; <br>make a trial operation record: every Check the current, temperature, voltage, vibration, etc. every half an hour; <br>after the operation is completed, restore the coupling, and perform the test operation under different conditions of load and full load. <br>Different equipment should be carried out according to the requirements of technical documents. <br>Quality assurance measures<br>The anchor bolts are oiled and rust-proof to prevent the anchor bolts from bending or being damaged by screws: the anchor bolts are coated with butter and wrapped with plastic cloth. <br>The arrangement of the horn and the specifications of the horn conform to the specifications: the horn is arranged according to the specifications, and the horn is machined. <br>When grouting the equipment, clean up the mortar dripping on the surface of the equipment in time to keep the surface of the equipment clean. <br>Improve the awareness of the whole staff on the protection of finished products to prevent bumping, smashing, electric arc scratching and contamination of the equipment surface. <br>Security measures
