How to maintain the automatic dosing machine?
In recent years, with the continuous improvement of environmental protection enterprises, the automatic dosing machine has made rapid progress at a certain level, and now the manufacturing enterprise has achieved technical changes, improving the production capacity and manufacturing level. Now let's talk about the maintenance methods of the automatic dosing machine?
When maintaining the automatic dosing machine, you should pay attention to the stability of the operation, and there should be no big vibration. If the vibration is large, the fault shall be eliminated in time. Of course, you should also pay attention to the indicator status of the pressure gauge, power meter and other instruments of the metering pump. If the pressure rises, check the cause, whether the discharge line is blocked or the valve is not opened. When the current increases to an abnormal level, check whether the pump itself and electrical equipment have faults. In addition to these, of course, the temperature rise of various moving parts and bearings cannot be too high, and the lubricating oil temperature cannot exceed 60 ℃. In addition to these, the reducer shall be refueled for 500 hours, that is, replaced with new oil, and replaced every six months after continuous operation. The lubricating oil shall be replenished frequently during use. The metering pump of the automatic dosing machine shall be replaced once a week and every six months after two months. The pump of the automatic dosing machine shall be replaced after 4000 hours of operation, and disassembled for cleaning after 8000-16000 hours of operation, except that some parts need to be replaced temporarily. Of course, it is necessary to keep it unblocked in time. The connection positions of equipment, filtering device, feed inlet, feed inlet, etc. are not detected on time, and the deposited components are observed at such positions.
When maintaining the automatic dosing machine, it is also necessary to regularly check the sedimentation delay at the metering pump inlet, and brush the pipeline and filter device on time to avoid delay. Regularly check the mixing device, supervise the deposition and rotation of the mixing shaft, twist and deform the centrifugal impeller, and loosen the coupling to prevent excessive shaft torque and consumption of mixing output power. If it is damaged, replace it as soon as possible. Of course, safety valves, pressure gauges and various pipeline valves need to be tested on time to prevent leakage. The standby pump and the application pump shall be used in turn to avoid long-term use or stop using the same pump. In addition, correct operation methods should be mastered. For example, connect power supply, pipeline and water source, and ensure basic safety. Then switch the change-over switch of the metering pump of the automatic dosing machine pump, the water inlet solenoid valve, the mixer of the dissolution tank, and the connecting valve between the original solution tank and the dissolution tank to the "remote" position. Adjust the stroke speed of metering pump on site. At this time, it is recommended that you move the floating balls in the box up and down one by one by hand to see whether the signal can be sent normally, and then check whether the liquid level alarm in the hopper can work normally. Return to the central control, enter the "automatic dosing machine system" interface, and manually adjust the output frequency of the metering pump.
