Automatic dosing device is a new upgraded definition of organic chemical wastewater treatment dosing machinery and equipment, which has been widely used in power engineering, public engineering, municipal engineering and other wastewater treatment industries all over the world. It is the dosing box, metering pump (diaphragm pump), automatic control system installed on a base. Connect the inlet and outlet of the metering pump (gear pump) with the dosing pipe, the import and export trade of the metering verification box and the water inlet, and send the switching power supply of the control box and the data signal of the measuring instrument to the control box to complete the overall composition of the function module of dissolving and dispensing the liquid medicine, metering verification and dosing.

In order to achieve remarkable results, it is necessary to automatically track and adjust the dosing rate of the added chemicals under the change of working conditions. Therefore, the superior automatic control system method is selected to operate the dosing device. In addition to some dosing pipes, sampling pipes and dosing concentration value measuring instruments, dosing device metering pumps are generally centrally installed in a dosing room to purchase, manufacture, assemble, adjust and test run dosing machinery and equipment. Customers only need to place the integrated automatic dosing equipment in the dosing room to ensure normal operation. That can greatly reduce the amount of construction labor on the spot and prevent the wrong operation of middlemen.

1. Before the installation of machinery and equipment, it is necessary to understand the structure of machinery and equipment and the engineering drawings presented, and check the basic equipment, the direction of branch pipe of machinery and equipment and the connection parts of various accessories according to the provisions of engineering drawings.

2. First, open the packing wooden box, remove the shell of the machinery and equipment, and then carry out on-site installation;

Machinery and equipment without package can be installed immediately.

3. According to the installation drawing of the water inlet, water outlet and overflow drain pipe, carry out the pipeline installation of machinery and equipment.

4. Remove the instrument panel of the supporting facilities of the machine and equipment from the packing wooden box, and carry out the installation and connection according to the installation drawing of the commodity appearance design under the condition that the instrument panel is intact.

5. This machine is equipped with a control box for household appliances. Customers only need to receive the power plug to the wiring input end of the air leakage switch in the electrical cabinet.

Characteristics: white powder or transparent beads and flakes. 30 g / cm3 (23 ℃). The coefficient of thermal expansion is 153 ℃ and the softening temperature is 210 ℃.

Dissolve water, and the solution is a symmetrical and clear liquid. The solution viscosity increased significantly with the increase of polymer content, and changed with the change of polymer concentration. Except formic acid, acrylic acid, ethylene glycol, Vaseline, melted urea solution and formamide, they are generally insoluble solvents. It is prepared by solution polymerization or dispersion medium aggregation of n-butyric acid. It has a variety of functions such as inclined plate sedimentation tank, thickening, drag reduction, bonding, stabilizing colloidal solution, demulsification and scale prevention.

Analysis of advantages of metering pump in dosing device

1. According to different process technology, the metering pump of the dosing device is accurately equipped with various solid and liquid chemical water solutions, and then the metering pump is used for accurate dosing, so as to meet the requirements of various design schemes. Such as scale cleaning, deaeration, concrete, adding acid and alkali, etc;

2. The whole process of dosing can be operated manually, and various household appliances and instrument panels such as PC, magnetic flap liquid level meter, pH meter, itinerary arrangement control panel, soft starter, etc. can be used to turn dosing equipment into electromechanical integrated commodity and complete automatic control system;

3. The dosage and working pressure of dosing pump of dosing device can be selected according to the need of industrial production. Suitable products can be selected in the range of total flow rate from 1L / h to 8000L / h and working pressure from 0.1MPa to 25MPa;

4. The precision of measurement verification of metering pump can reach ± 1%, and can complete a variety of material transportation, independent adjustment.
