Dosing metering pump metering method

Dosing metering pump is used to transport liquids (especially corrosive liquids) A special volume pump, plays an important role in daily production and life. So the face of the market a large number of dosing pump model, dosing pump users how to choose it? This small series for your interpretation of dosing metering pump metering methods.

Dosing metering pump metering method

First, determine the pressure: The selected pressure pump metering pressure to be slightly higher than the actual maximum pressure required, generally higher than 10 to 20%. Do not choose too high, too much pressure will waste energy, increase equipment investment and operating costs.

Second, determine the flow: The selected metering pump flow should be equal to or slightly larger than the flow of technology required. Dosing pump flow range of use in the metering pump rated flow range of 30 to 100% better, then the metering pump repeated reproduction of high precision. Considering economical and practical, it is suggested that the actual required flow rate of the metering pump should be selected to be 70-90% of the rated flow rate of the metering pump.

Third, to determine the pump head (hydraulic end) Material: The specific model pump metering specifications are determined, and then select the over-flow medium according to the properties of the material flow section, this step is very important, if not properly selected, will result in medium corrosion damage Overcurrent components or media leak contaminated systems. Serious accidents may also result in serious problems, if you are not sure, please consult our company.

other aspects:

When you select the metering pump, you also need to consider the required metering pump accuracy level, the higher the level of precision into more.

Metering pump general operating temperature -30 ~ 100 ℃, special metering pump its working temperature range is wider (such as high temperature liquid metering pump with insulation jacket, the delivery temperature up to 500 ℃).

For media size, we require less than 0.1mm, for media greater than 0.1mm, we can be targeted to the pump overcurrent structure to meet the needs.

For medium viscosity, generally should be 0 ~ 1000mm / s, special metering pump up to 6000 mm2 / s, my company has a high viscosity pump head.

The flow rate of a mechanical diaphragm metering pump is the maximum flow rate measured at a nominal pressure rating (when water is delivered at room temperature). If the pressure drops, the output flow rate will be higher than the nominal value.
