4.2 Funktion
General:
The small, compact and powerful DESOI PowerInject P1 is suitable for machine-accessible injection resins.
The main areas of use are smaller construction site projects. The structure of the mechanism turns a rotary motion into a linear piston
movement. Operating pressures up to 200 bar can be achieved via the ratio of piston diameter, piston stroke and pressure control
valve. The special feature is that the excess medium is returned to the material container through the return discharge when the set
operating pressure is reached. Clogging of the manometer is not possible because direct contact with the injection resin is prevented
by a pressure measuring unit with membrane and oil filling.
Functional principle of a piston pump:
(Fig.4.2.1)
The DESOI PowerInject P1 is electrically operated. The piston operates in a suitable cylinder tube. Due to the retraction movement of
the piston, the injection material is moved from the material container into the delivery chamber. During the forward movement, the
injection material is forced out of the delivery chamber again by the outlet valve. During the forward movement, the piston closes the
inlet hole for the injection material, so that it is not immediately forced back into the material container.
