What maintenance work is required for the air flotation machine in routine operation?

The air flotation machine mainly organically integrates an air pool, dissolved steam tank, centrifugal water pump, drug delivery equipment and air compressor or ejector. It occupies a small area and is easy to operate. It can also reduce installation operations and labor workload. Air flotation equipment mainly uses the micro-bubbles in the water to bond together with the suspended solid flocs, and the suspended solids rise to the river surface together with the micro-bubbles, generating sludge to remove the floating flocs in the water. The user of this equipment only needs to adjust the pH The value of waste water to the inlet and outlet branch pipes can be operated normally after adjustment. It does not need full-time personnel to manage, and the operation is basically automatic. However, under the normal operation of the equipment, daily maintenance is also essential.
1. Regularly check the filling material and air intake system of the air compressor and centrifugal water pump, and oil frequently.
2. Check the water surface of the air flotation machine. If you find that the mud surface in the contact area is uneven, some large bubbles appear or the water flow is unstable, you should remove the blockage of the safety pressure relief valve; if the mud surface in the separation area is uneven, the surface of the pool often has If large bubbles burst, the adhesion between the bubbles and the flocs is not good. It should be detected and the coagulation system should be changed or appropriate measures should be taken (such as adding surfactants, etc.).
3. Make a good record of the daily operation of the air flotation machine, including solving the water flow, dosage, water flow of the air flotation device, working pressure of the steam tank, water temperature, electricity consumption, water in and out, cycle time of slag cleaning, and water content of slag wait.
4. In winter when the water temperature is too low, because the flocculation effect is poor, in addition to the need to increase the dosage, sometimes the air flotation machine must correspondingly increase the water flow or pressure to allow more and more microbubbles to adhere to the flocs. To make up for the increase in the viscosity of the flowing water that affects the upward adjustment characteristics of the air-filled flocs, thereby ensuring the normal water output.
5. According to the flocculation of the reaction tank, the sludge in the air flotation area and the water output, pay attention to adjusting the main parameters such as the amount of mud of the flocculant, especially to prevent the blockage of the dosing pipe.
6. Frequently check the water level indicator tube of the steam tank to keep it within a certain range (generally within 60-100CM). To ensure the actual effect of the air flotation machine. Prevent the misalignment of the water level line of the dissolved steam tank, causing a large amount of gas to escape into the floating tank and destroy the water purification effect and sludge layer. For those equipped with an automatic control system for the liquid level gauge of the dissolved vapor tank, special attention should be paid to the maintenance of the equipment.
