The dosing metering pump is a device specially used for metering and conveying liquids, especially in the process where the amount of

 drug addition needs to be accurately controlled. The following is a detailed introduction to the dosing metering pump:

1. Definition and characteristics

Definition: The dosing metering pump, also known as the dosing pump, is a machine that can measure the delivered liquid and is often

 used in various types of drug addition equipment.

Features:

Meet various strict process requirements.

The flow rate can be adjusted steplessly in the range of 0-100%.

Especially suitable for conveying corrosive liquids.

2. Structural principle

Structure: The dosing metering pump is mainly composed of three parts: motor, transmission box, and cylinder body. Among them, 

the transmission box component is composed of a cam mechanism, a stroke adjustment mechanism, and a speed ratio worm gear 

mechanism; the cylinder body component is composed of a pump head, a suction valve group, a discharge valve group, a diaphragm 

diaphragm base, etc.

Working principle: The motor drives the worm through the coupling and reduces the speed of the worm gear to make the main shaft 

and the eccentric wheel rotate, and the eccentric wheel drives the tappet to reciprocate in the guide cylinder. Through the action of the

 one-way valve, a vacuum is gradually formed in the pump chamber, the suction valve opens, and the liquid is sucked in; when the 

diaphragm moves to the forward dead point, the suction valve is closed, the discharge valve opens, and the liquid is discharged under

 the push of the diaphragm.

3. Flow regulation characteristics

Flow regulation is to rotate the adjustment handwheel to drive the adjustment screw to rotate, thereby changing the spacing between

 the tappets and changing the movement stroke of the diaphragm in the pump chamber to determine the size of the flow.

The scale of the adjustment handwheel determines the diaphragm stroke with an accuracy of 95%.

4. Application scenarios

Water treatment field: In the water treatment process, the dosing metering pump can accurately control the concentration and flow of

 the added agent to ensure that the water quality meets the specified standards.

Food processing field: In the food processing process, the dosing metering pump is widely used in the addition process of syrup, food

 seasoning, juice, pigment and flavor to ensure the stability of food quality.

5. Selection guide

The following aspects need to be considered when choosing a dosing metering pump that suits you:

Flow range: Different models of dosing metering pumps have different flow ranges, which need to be selected according to actual needs.

Required accuracy: Different industries and different production processes have different requirements for the accuracy of dosing metering.

 It is necessary to select the appropriate accuracy level according to actual needs.

Working pressure and working temperature: The working pressure and working temperature of the dosing metering pump are related to 

the selected working medium. It is necessary to select a suitable dosing metering pump according to the actual medium pressure and 

temperature.

Working medium: The material of the dosing metering pump needs to match the selected working medium. It is necessary to select a 

suitable material according to the chemical properties of the actual medium.
