计量泵是如何工作的?

Dosatron is the original inventor of the non-electric proportional dosing pump since 1974.
Dosatron technology is a passive volumetric dosing pump based on a water driven hydraulic motor piston pump activated only by pressure and flow of water without any electricity or any measuring device.
Such a pump is composed of two main elements: a passive water driven hydraulic piston and a dosing piston.

How does the hydraulic piston work?

The motor piston moves under the pressure of water. A system of valves allows the movement to be reversed. This water powered piston creates a reciprocating motion along the axis of the pump body.
Each piston cycle corresponds to a predetermined volume of water, which passes through the pump. The speed of the motor varies proportionally to the water flow.


How does the dosing piston work?

The dosing piston, driven by the hydraulic piston, mechanically displaces the volumes of fluid trapped in the system. On the suction side, the volume expands, while on the discharge side, it contracts. The volume per stroke is therefore fixed and theoretically constant, regardless of outlet pressure, inlet vacuum or fluid properties.

Summary

Dosatron has been a dosing pump manufacturer for almost 50 years.
The Dosatron is a passive non-electric volumetric proportional dosing pump without measuring device composed of two volumetric reciprocating pistons, the first one acting as hydraulic volumetric piston to create a linear movement, the second acting as volumetric and proportioning positive displacement reciprocating dosing pump.

Advantages of the Dosatron pump

  • Non-electric
    Unlike electric pumps, the Dosatron metering pump is activated only by pressure and flow of water.
  • Dosing accuracy
    The high precision of the constant dosing of the hydro-motor pumps eliminates any risk of overdosing, saving the concentrated additive and contributing to the respect of the environment.
  • Proportional dosing and homogeneous solution
    It has been designed to inject the precise dose of concentrated additive that is continuous, homogeneous and directly proportional to the volume of water entering the dosing pump, regardless of the variations in flow and pressure that may occur in the water system.
  • Low operating costs
    Life cycle costs are very low due to its electric-free, servo-free design and easy maintenance.

The proportional dosing unit integrates 4 functions realized by mechanical construction.

  • Measuring: hydraulic volumetric motor for water flow,
  • Dosing: continuous proportional injection of liquid or soluble concentrate,
  • Regulating: proportionality controlled by the water flow,
  • Mixing: homogenisation integrated in the pump body.
