How to divide the flow of pneumatic diaphragm pump?

The flow rate of pneumatic diaphragm pump refers to the amount of liquid transported by the pump per unit time. Liters per minute (L/min), liters per hour (L/h) or cubic meters per hour (m? /h) and other units. The flow of pneumatic diaphragm pump is affected by the following factors:

Pump size and design: Different models and sizes of pumps have different flow ranges. Large pumps usually have high flow, while small pumps have relatively low flow. When selecting the pump, it is necessary to select the appropriate pump type and size according to the actual application requirements and flow requirements.

Driving air pressure: the working principle of pneumatic diaphragm pump is to use compressed gas (usually air) to drive the diaphragm to reciprocate, so as to realize the suction and discharge of liquid. The flow rate of the pump is affected by the driving air pressure. The higher the air pressure, the greater the flow rate of the pump. By adjusting the driving air pressure, the flow rate of the pump can be adjusted within a certain range.

Properties of the transported liquid: The viscosity, density and temperature of the transported liquid will also affect the flow rate of the pump. For liquids with high viscosity, the flow rate of the pump may decrease; For liquids with low viscosity, the flow rate of the pump may increase. In addition, the density and temperature of the liquid will also have a certain impact on the flow of the pump.

Suction and discharge pipes: the diameter, length and number of elbows of the suction and discharge pipes of the pump will also affect the flow rate of the pump. Too small pipe diameter, too long pipe length or too many elbows may lead to excessive friction loss, thus reducing the flow rate of the pump. Optimizing pipeline design and layout can improve pump flow and work efficiency.

The following methods can be used to adjust the flow of pneumatic diaphragm pump:

Adjust the driving air pressure: By adjusting the driving air pressure, the flow rate of the pump can be adjusted within a certain range. Increasing the air pressure can increase the flow rate, while decreasing the air pressure can decrease the flow rate.

Selection of appropriate pump type and size: According to the actual application requirements and flow requirements, select the appropriate pump type and size. Different models and sizes of pumps have different flow ranges.

Optimize pipeline design and layout: adjust pipeline diameter, length and elbow number to reduce friction loss and improve pump flow and work efficiency.

Use throttle valve: a throttle valve is installed at the outlet end of the pump, and the flow rate of the pump can be changed by adjusting the opening of the valve. It should be noted that the use of throttle valve may increase the energy consumption of the system and reduce the efficiency of the pump.

Consider the nature of the liquid: understand the influence of viscosity, density and temperature of the transported liquid on the pump flow. According to different liquid properties, select appropriate pump type and operating parameters to achieve ideal flow control effect.

In a word, many factors need to be considered to adjust the flow of pneumatic diaphragm pump, such as pump design, driving air pressure, the nature of conveying liquid, pipeline layout and so on. By reasonably selecting the type and size of the pump, adjusting the driving air pressure, optimizing the pipeline design and installing the throttle valve, the flow rate of the pump can be adjusted within a certain range.
