What is the structure of dosing equipment and how to solve common problems?

The structure of the dosing equipment includes intelligent control box, electromagnetic diaphragm metering pump, PE anti-aging dosing bucket and low liquid level alarm device. In addition, common problems such as: the inlet pipeline is blocked or the resistance is too large, the solution is to dredge the inlet pipeline and take corresponding measures to reduce the resistance; The following is a detailed description of the relevant content.

1、 Structure composition of dosing equipment

1. Intelligent control box:

The intelligent control box of dosing equipment is the brain and control command center of the whole dosing system, which coordinates the work of all parts of the whole system and adopts two-way output time control switch control.

(1) On line control the opening and closing of dosing pump;

(2) On line control the remaining amount of the medicine in the medicine barrel of the dosing system, and give the alarm signal when the liquid level is low.

2. Electromagnetic diaphragm metering pump:

When the intelligent control of the dosing equipment reaches the preset initial time value, the metering pump is opened to start dosing; When the end of time is reached, the metering pump is shut down and the dosing is stopped.

The electromagnetic diaphragm metering pump is imported, with stable performance, accurate and uniform dosing, corrosion resistance, good tightness, small volume and high metering accuracy. The dosing amount and output pressure can be adjusted steplessly according to the actual needs of the site. The domestic metering pump can also be selected according to the user's requirements. According to the front of the control box, the metering pump on the left side of the control box is No. 1 metering pump, and the metering pump on the right side is No. 2 metering pump.

3, PE anti aging medicine barrel:

The medicine adding equipment is a container for water treatment chemicals. The round, PE anti-aging material will not become brittle and cracked. The service life will be more than 10 years. It is specially designed for automatic dosing equipment. It is rigid, even if it is full load, it will not be deformed. The translucent material is easy to observe the chemical residue in the barrel from outside. The high rigidity of the top cover enables it to provide enough support and position for installing metering pump, low liquid level alarm device and liquid mixing agitator (optional).

4. Low level alarm device:

The volume of the medicine barrel of the dosing system of the dosing equipment is fixed, but the dosing time and dosage are uncertain. The engineer on duty can not accurately grasp the remaining amount of medicine in the medicine barrel and replenish it in time. After a period of time, the medicine will be added completely, and the dosing pump will not be powered off, so the phenomenon of empty operation without medicine will appear in the dosing pump, If the dosing pump is empty for a long time, it will burn the control motor of the dosing pump, damage the dosing pump and affect the normal dosing of the system.

2、 Solutions to common problems of dosing equipment

1. The inlet pipeline is blocked or the resistance is too large

Solution: dredge the inlet pipeline and take corresponding measures to reduce resistance.

2. Air inlet at inlet pipe connection:

Solution: tighten the connection thread or seal the interface.

3. Serious leakage of packing;

Solution: tighten or replace packing.

4. There is air in the pipeline in the pump body:

Solution: remove the air.

5. The inlet and outlet check valves are not closed tightly

Solution: check the valve seat, clean or replace the valve ball.

6. Leakage of gasket at inlet and outlet check valve:

Solution: check the sealing surface or replace the sealing ring.

7. The oil replenishing valve does not replenish oil,

Solution: insufficient oil supplement, frequent oil supplement or leakage: adjust the spring tightness of oil supplement valve or repair the sealing surface of oil supplement valve, clean and replace the steel ball.

8. Frequent tripping of safety valve:

Solution: adjust the spring tightness, find out the reason and take measures to eliminate it.

9. The sealing of the limiting plate in the diaphragm cavity is not tight

Solution: tighten the screw at the end of the pump head or find out the reason to eliminate it.

10. The hydraulic oil is not clean, causing abnormal operation of the three valves

Solution: change clean hydraulic oil.

In addition, in order to avoid the failure of the dosing device, the safety valve, pressure gauge and pipeline valve should be checked regularly to avoid failure.
