Vertical mud pump when used matters needing attention
1) vertical mud pump uses three-phase four-wire power supply, and must be installed ground wire to prevent leakage. In order to facilitate the control and motor matching circuit fuses and switches to be installed nearby. 2) When using the mud pump, it can operate without installing any basic device, as long as it can be leaned firmly, if necessary, use a rope to fasten to prevent accidents. The motor can not be reversed, immediately after starting to see and found the reverse immediately stop, replace any two power lines can be reconnected. 3) When the liquid being sucked in contains more weeds, wire, wood, bricks and other debris should be properly installed barrier grid or filter to prevent debris from entering the pump to break the impeller, Stuck. And plug the pipeline and other accidents. 4) The suction pump in the body of other contaminants, should absorb water rinse. 5) Mud pump suction thick mud, concentrated liquid or high-lift long-distance operation, the load will be reduced, but can not change the structure of the method to increase the load. 6) When working in the open air, the motor should be fitted with a protective cover to prevent the rain and the like from immersing in the motor. 7) At the bottom of the river, sump should be hung on the tripod on the bottom of the pool, and can be put on the floating Jane or the ship to move the homework. When carrying out earthmoving work, the diameter of the clod which is broken by the high-pressure water gun shall not be larger than 1/3 of the suction port. 8) The mud pump should be operated at the specified speed and can not be changed freely. If the speed is reduced, the power will be significantly reduced. Increasing the speed will increase the stress of the mud pump parts and damage the parts. 9) The filler should not be too tight, can be loosened before starting, and then adjusted. 10) should not be immediately after the parking for the second start, so as not to rush back to the impeller, easy to make the motor damaged. 11) In the course of operation, should always pay attention to the motor and pump whether there is abnormal noise or bump into the vibration; often check whether the bearing parts are hot (generally should not exceed the outside temperature 35 ° c), if any abnormal phenomenon should be immediately Parking inspection, to be troubleshooting before work.
