The mechanical diaphragm metering pump works the principle you know, the diaphragm metering pump manufacturer koyu machinery to introduce to you today.

Analysis of working principle of mechanical diaphragm metering pump

1. The mechanical diaphragm metering pump is driven by the motor through direct coupling drive to drive the worm gear, and the rotary motion is transformed into reciprocating linear motion with the action of the crank connecting rod mechanism. Slider and diaphragm direct connection, work in reciprocating motion directly push the slider move back and forth diaphragm (la), through the role of the one-way valve open/close pump head absorption purpose, achieve the function of the liquid.

2. It is the machine that can measure the conveying liquid, also known as the ration pump and proportional pump. Usually described as: mechanical diaphragm metering pump is a kind of can meet the demand of all kinds of strict process flow, flow can be adjusted within the range 0-100%, used for conveying liquid (particularly corrosive liquid) is a kind of special displacement pump.

Mechanical diaphragm metering pump selection parameters

1. Flow of measured liquid.

2. The main characteristics of the liquid being measured, such as chemical corrosion, viscosity and gravity, etc.

3. System back pressure.

4. Proper suction height.

5. Other options required, such as analog control, pulse volume control, flow monitoring, and timer.

The mechanical diaphragm metering pump has the main advantages

The electromagnetic drive metering pump has only one moving part - the pivot axis. Generally speaking, the less moving parts, the more reliable the metering pump. The metering pump is suitable for low flow and low pressure working conditions, and it can compensate for the fluctuation of power supply voltage.

Compared with the fixed frequency and the metering pump with varying stroke length, what are the advantages of fixed stroke length and changing frequency metering pump? By correction, the amount of each stroke is known. Therefore, the total amount of total investment can be calculated by calculating (the amount of each stroke is equal to * frequency). The total amount is linearly dependent on the frequency (50% frequency =50 %). With external pulse or analog control, the amount can be shifted from the smallest to the maximum in a second. In addition, it is much lower than the motor drive length adjustment cost.
