Sawing machines, metal band saws, and angle band saws have been widely used, and their convenient and efficient work efficiency has been favored by many people. Of course, some troubles and problems in the use of metal band sawing machines are difficult to avoid. If you want to use the equipment for a longer period of time, daily maintenance is a must.

The role of metal band saw pumps is great, and there are also some problems that are difficult to solve. Today, we will first introduce to you how to maintain the metal band sawing machine pump.

1. When cleaning, the water pump, valve, pipeline, etc. connected with it should be cleaned and maintained with the pump, and check whether the seal at the pipeline seal is outstanding. If there is water leakage, air leakage and repair and replacement parts.
2. Check if there is any external damage or bump at the pump body. The column shaft coupling screw and rubber should be replaced if damaged.
3. Fasten the machine base screws and prevent rust. The appearance should be neat and tidy, the nameplate is intact, and the grounding wire connection is outstanding.
4. Regularly add lubricating oil to the band sawing machine pump. If the oil is discolored, there are impurities and replace the new lubricating oil in time.
5. There is no crack on the outside of the pipeline and each accessory. The action of the check valve should be active, and there is no water leakage in the valve body. The switches of each valve should be reliable and there is no leakage in the table. Jog to determine whether the pump steering is accurate, if it is wrong, it should be corrected. It is necessary to clean the flow path of the clean impeller and the sawing pump pump body.
6. When the metal band sawing machine pump is faulty, the wire connecting piece in the motor terminal box can be disassembled, and the motor winding phase and phase are measured by a 500V megger. The insulation resistance value between the grounding should be not less than 0.5 megohm. The three-phase wires and gussets in the motor junction box should be robust and rigorous.

When the metal band sawing machine is used for maintenance, the pump, valve, pipeline, etc. should be planned to be maintained at the same time with the pump. Check the sealing condition. If there is any leakage, increase or replace the seal. Compensation lubricant, if the oil is discolored, there are impurities, should be replaced. Check that the pump body of the band sawing machine should be free from damage, the nameplate is intact, the direction of the water flow is clear, the appearance is regular, and the paint is intact. The column shaft coupling screw and rubber should be replaced if damaged. Fasten the base screws and prevent rust. The appearance should be regular, the nameplate is intact, and the grounding wire connection is outstanding. Disassemble the wire coupling piece in the motorized junction box of the band sawing machine, and measure the phase and phase of the motor winding with a 500V megger. The insulation resistance between the grounding should be no less than 0.5 megohm. The three-phase wire and the gusset in the motor junction box should be strong and rigorous. The appearance of the pipes and accessories is beautiful and without cracks, and the paint should be free of defects. The check valve action should be active and there is no water leakage in the valve body. The switches of each valve should be reliable and there is no leakage in the table. Jog to determine whether the pump steering is accurate, if it is wrong, it should be corrected.
