Full automatic double cylinder and double pump dosing device for air conditioning system 200L time level control

full automatic double cylinder and double pump dosing device for air conditioning system 200L time level control circulating water dosing device, usage method of full-automatic dosing device

Abstract: the user configures the reagent according to the proportion of the feeding solution, and accurately adds it through the metering pump

1. Connect the dosing device, then check each flange interface and tighten it to avoid fluid leakage

2. Connect the power supply of the metering pump: the dosing device is used to configure the reagent according to the proportion of the feeding solution, and accurately add it through the metering pump. 1. Connect the dosing device, and then check each flange interface and tighten it to avoid fluid leakage

3. Connect the power supply of the metering pump: (1) open the junction box of the electric control cabinet, and connect the three-phase four wire power line that meets the requirements of the metering pump motor to the corresponding wiring terminal. (2) Start the mixer instantaneously by controlling the operation switch, observe the rotation direction of the motor, and fix the junction box if the rotation direction is correct. If the steering is incorrect, adjust the phase sequence and then fix the junction box

4. Close the blowdown valve. Fill the container with liquid medicine

5. Open the valve of the dosing system and start the metering pump

6. The dosing device is equipped with two metering pumps, one for dosing and the other for standby. Special attention: 1. When dosing, open one pipeline corresponding to the starting metering pump (ensure that the metering pump and related pipelines are unblocked and intact), and close the other pipeline. 2. An overflow pipe is set at the top of the device to prevent the overflow of the liquid medicine from flowing out through the sewage pipeline. 3. A tubular filter is set at the inlet of the dosing metering pump to prevent large particles of solid substances from entering the metering pump and damaging the metering pump. The pipeline of the maintenance dosing device in front of the dosing head should be kept unblocked at any time, and the connecting parts, filters, feed ports, discharge ports, etc. of the device should be checked regularly and irregularly to observe whether there are deposited substances in these parts. If these symptoms are found, it should be prompted in time: the experimental curve can be enlarged and then the "yield point" can be reconfirmed and cleaned. The air conditioning system is fully automatic to make it coincide with the main needle. The 200L time liquid level control of the double cylinder and double pump dosing device should regularly check whether the feeding inlet of the metering pump is blocked, and the pipelines and filters should be cleaned regularly to prevent blockage. Regularly check the mixing device to see whether the mixing shaft rotates flexibly, whether the impeller is twisted and deformed, and whether the coupling sleeve is loose, so as to avoid excessive shaft torque and consumption of mixing power. If it is damaged, it should be replaced in time. Check the safety valve, pressure gauge and pipeline valves regularly to avoid leakage. The standby pump and the use pump should be used alternately to avoid long-term use or shutdown of the same pair of pumps in flexible packaging enterprises

structure of 200L time liquid level control dosing device for fully automatic double cylinder and double pump dosing device for air conditioning system

the automatic control device is mainly composed of automatic control cabinet, recorder, AC motor, dosing pump, etc. There are frequency converters, regulators, detectors, etc. in the automatic control cabinet, as shown in the table below. The selection of the detector depends on the type of dosing of the user, for example: ammonia dosing, conductivity meter or pH meter can be selected for the detector, rapid phosphate analyzer can be selected for phosphate dosing, pH meter can be selected for neutralization tank, R meter is required for coordinated phosphate treatment, flowing current meter is used for coagulation, residual chlorine meter is required for chlorination, etc
