Problems solved by technology

This intermittent operation of the vacuum generator is inefficient (higher energy consumption) and causes greater wear and tear on the generator, resulting in increased system maintenance
Also, the on-off control of the ejector, when the generator is running at a constant high speed (when running), creates more friction (heath) on the ejector, thus creating higher temperatures in the ejector, when When using a liquid ring pump, causes the liquid in the pump to evaporate and soon the liquid ring in the pump fails
This failure will result in a loss of vacuum in this pump

Embodiment Construction

[0012] As mentioned above, figure 1 An example of a vacuum drainage system is shown comprising two vacuum generators 1 connected in parallel in the form of liquid ring screw pumps with integrated macerators, a common suction line or collection pipe 2, connected at one end to a vacuum The generator is also connected with a plurality of toilets, urinals 3, 4, etc. through the branch pipeline 6 at the other end. When flushing the toilet or urinal, etc., the vacuum generator 1 generates a vacuum in the common suction line 2 and the branch line 6, continuously sucks and fills liquid and air into the generator, and discharges it through the outlet 5 of the generator.

[0013] As mentioned above, figure 1 The system shown is normally controlled by the on / off operation of the vacuum generator. Therefore, when the system is in a low mode state of use, for example, at midnight, with only a few or no toilets being used, only A vacuum generator is running. Once the vacuum generator re...

Abstract

Method for controlling one or more vacuum generators (1) and thereby the vacuum in a vacuum sewage system, in particular controlling one or more liquid ring screw pumps in such system, including beyond the generator / s (1) one or more tubular collectors or suction pipelines (2) connected to the vacuum generator and one or more toilets, urinals, grey water sinks etc (3, 4), connected to the suction pipeline through branch pipelines (6). The rotational speed of the vacuum generator (1) is controlled on the basis of the set vacuum requirement.

Description

technical field [0001] The present invention relates to a method of controlling the vacuum generator and thus the vacuum level in a vacuum drainage system, and in particular to the control of one or more liquid ring screw pumps in a system comprising, in addition to the generator, a pump connected to the vacuum generator One or more tubular collectors or suction lines and one or more toilets, urinals, gray water drains, etc. connected to the suction line. Background technique [0002] Vacuum drainage systems of the type described above are common and are often used on ships, aircraft and trains. However, on land, such systems are also increasingly used, mainly because of the low water consumption, ease of operation and simple treatment of waste water, and the benefits achieved by such systems. Flexible system in terms of pipe installation. [0003] The applicant of the present application introduced a new vacuum drainage system in European Patent 0287350 of 1987, in which ...
