When an industrial circulating cooling system operates naturally, it may be affected by the hardness and alkalinity of the circulating water.pHIt is influenced by factors such as value, concentration ratio, air temperature and ambient temperaturewhileScaling or corrosion tendencies occur, which have adverse effects on the system and operation. To inhibit the occurrence of scaling or corrosion, it is necessary to add it to the waterCorrosion inhibitors or scale inhibitors.

The scale inhibitor dosing device mainly consists of four parts: the liquid medicine dissolution and preparation system, the metering and dosing system, the system and the control system. Solid chemicals are added to the dissolving tank, and then demineralized water or condensate water is added in proportion and stirred to dissolve. They are then added to the boiler drum by the metering and dosing system. The dosing control can be carried out manually or automatically based on the control signal output by the upper-level system for following control.Now let's talk about how to operate and maintain the scale inhibitor dosing device?

I. Installation and commissioning of equipment

1,The mixing tank is cleaned and the wastewater is discharged from the sewage outlet of the liquid storage tank.

2,Check whether the stirring device is installed stably and firmly. And check whether the power is connected before putting it into use,Ensure the equipmentIt is normal if there is no noise and it operates smoothly.

3,Check whether the metering pump is installed stably and firmly. And check whether the power is connected.

4,Check whether all pipes, components, etc. are installed properly.

Ii. Operation and Usage

1,Check whether the foot platforms of the dosing device are on the same horizontal line. The pump outlet has threaded connectors, quick couplings and flange connectors. Connect the corresponding connectors properly and then connect the power supply.

2,Make thorough preparations before operation. Inject an appropriate amount of mechanical oil into the metering pump box and the reducer box, with the oil level line as the standard.

3,Close the drain valve and pipeline valve, and add the liquid medicine automatically or manually. Connect the power supply and the electrical control cabinet. If the power indicator light is on, it indicates that the power is connected. Press the button on the mixing tank and the mixer will start working5minAfter that, open the pipeline valve, open the flow control valve, press the start button of the metering pump, and the metering pump will start to work.

4,It is necessary to regularly check whether the feed port of the metering pump is blocked and clean the pipelines and filters regularly to prevent blockage.

5,Regularly inspect the stirring device to check whether the stirring shaft rotates flexibly, whether the impeller is twisted or deformed, and whether the coupling sleeve is loose, so as to avoid excessive shaft torque and consumption of stirring power. It should be replaced in time if it is damaged.

6,In the device, regular inspections of valves, pressure gauges and valves of each pipeline should be carried out to prevent leakage incidents. When using two pumps for dosing, they should be used alternately to avoid keeping the same pump in use or out of service for a long time.

Iii. Daily Maintenance and Care

1,Check every day whether there are corrosive gases and fluids around the equipment. Check the sealing performance of the air pressure pipeline. If there is any air leakage, it should be repaired in time.

2,The valves should be checked every month to ensure they are flexible and unobstructed. Check whether the can body is rusty or damaged and repair it in time. Check if the screws are loose or ineffective.

3,Check every year whether the welds are firm and whether the sealing rings are aged. Paint the tank body once a year for anti-rust treatment.
