Problems solved by technology

In this way, motor-driven metering pumps usually cannot be adjusted according to the required accuracy within a wide operating pressure range; in addition, errors caused by calibration will become more serious in subsequent further calculations
However, said calibration measurements, which must be performed in use under real operating conditions, are a very difficult step, especially when aggressive chemicals are used

Embodiment Construction

[0057] figure 1 The structure of a motor-driven metering pump is shown (partial cutaway). As generally known, a motor-driven metering pump basically consists of three groups of elements, namely the drive motor 2 with transmission, the cam driver in the cam housing 1, and the electronic control unit housed therein with the on-board electronic module And the electronic housing 28 of the block. Below the electronic housing 28 there is a support plate 4 with a fixing hole; the cam housing 1 positioned on and fixed to the electronic housing carries the drive motor 2 with a transmission, which is attached, for example, with screws. The drive motor is fixed to the cam housing.

[0058] The housing consisting of the cam housing 1 and the electronics housing 28 has the elements of the cam drive on its upper part, ie on the cam housing 1 . The individual elements of the cam drive are accommodated in a cam carrier 22 which ensures that the individual elements are accurately positioned...

Abstract

The invention relates to a metering pump which is provided with a rotation driving motor and a swing piston; wherein, the rotation motion of the driving motor is converted into the swing of a connecting rod by a transmission device, thus leading the displacement device driven thereout to carry out a linear swing with the continuous rotation of the driving motor; therefore, the medium to be measured is transmitted in a metering head (12); the metering head is arranged along the longitudinal axis line of a connecting rod (19) and is alternatively matched with an outlet valve and an inlet valve so as to generate a pumping stroke (pressure stroke) and a filling stroke. In the metering pump, a reference element (35) is relevant to the connecting rod; the position of the connecting rod is detected by a position sensor; wherein, the position sensor provides a practical signal (x1) which forms a fixed relation with the position of the reference element, thus forming a fixed relation with the position of the displacement device; furthermore, the signal also provides an information which is corresponding to the motion of the displacement device, therefore, the electronic control system of the metering pump can respond to the metering circuit and the operation conditions of the pump.

Description

technical field [0001] The invention relates to an electric motor driven metering pump according to the preamble of claim 1 . Background technique [0002] Electric motor driven metering pumps of this type are known and accessories are available to suit various needs. They work on a volume basis, where metering takes place by conveying a closed volume through a displacement device. In this way, the metered volume per stroke corresponds to the volume difference according to the movement of the displacement device. [0003] In general, such a motor-driven metering pump converts the continuous rotational motion of the drive motor into linear oscillating motion of the displacement device through a transmission. The rotational speed and torque of the electric motor is reduced in the transmission and matched to the speed and power required by the displacement device. The output shaft of the transmission drives the means for converting the rotary motion into a lateral, ie offset...
