Definitions

• the invention relates to a system and a method for controlling a liquid flow in a line, with a liquid conveying the liquid to the consumer, container or process pump.
• the invention relates to a service water supply system for the public water supply, with a water supply pipe network of several water supply lines and at least one service water through the water supply lines to a consumer-promoting motor pump.
• the object of the invention is to provide a system and a method of the type mentioned, which does not have the aforementioned problems in particular the losses of the throttle body with high efficiency. It is also an object of the invention to achieve a needs-based supply of processes and system components, so that the energy consumption of the pump can be significantly reduced.
• a wastewater disposal plant can be used, with a sewage pipe network of several sewers and with at least one wastewater through the sewers to a settling tank or clarifier promotional motor pump, instead of located in the sewers, the waste water flow controlling sliders the pump in their flow is controlled as needed and in particular no further control or throttle body is arranged to control the flow in the sewers.
• the basic idea is to replace the slider in the wastewater disposal system controlling the waste water flow through the pipes by regulating the pump, in particular its speed, which pumps the waste water. For the operation of the wastewater system with a 50 percent closed slide this slide can be replaced by the fact that the pump Approximately half of their power respectively their speed or to obtain a certain control reserve is adjusted to slightly less than half of their power automatically or set.
• a slide in a wastewater treatment plant according to the prior art be closed, this case of operation can be achieved according to the invention by an automatic deactivation of the pump or setting the pump to a minimum of their power respectively their speed.
• This has the advantage that the pump does not have to work against one or more closed slides.
• the slides can be replaced by speed-controlled pumps.
• sliders may still be provided in a plant to completely stop the flow of sewage through the pipes in an emergency, such sluices do not participate in controlling the pump flow or sewage flow through the sewers. This is done exclusively by the need-based adjustment of the power respectively the speed of the pump.
• a service water supply system for the technical field of public water supply a service water supply system is proposed, with a water supply pipe network of several water supply lines and at least one service water through the water supply lines to a consumer-promoting motor pump, instead of located in the water supply lines, the water flow controlling valves, the pump in their flow, in particular in their speed, is regulated as needed and in the water supply lines no further control or throttle body is arranged to control the flow rate.
• valves in the water supply system which control the process water by the lines by regulating the pump, in particular its speed, which pumps the process water or generates the pressure in the lines . If the water supply system is removed a lot of water, the water demand is therefore correspondingly high, the pump can operate with a high power, in particular a high speed and provide a correspondingly high pressure in the line. If, on the other hand, little water is withdrawn, it is sufficient for this case of operation to operate the pump automatically with low power or low speed, so that it does not counteract one or more closed valves are working. Above all, the valves can be replaced by speed-controlled pumps.
• the service water supply system may have a valve, for example in the form of a faucet or other valves as the conclusion of a water pipe.
• a valve for example in the form of a faucet or other valves as the conclusion of a water pipe.
• these are not actuators for controlling the water flow, since according to the invention this is provided by the pump and the pump is the corresponding actuator.
• Such valves are therefore not involved in controlling the pump flow or the flow through the water supply lines. This is done exclusively by the need-based adjustment of the power respectively the speed of the pump.
• a remplissigkefts constitusstrom can be used, with a liquid pipe network of several pipes, which may be formed in particular by tubing, and at least one of the chemical fluid in the process-promoting motor pump, wherein instead of in the valves located valves, taps or flaps that control the flow rate of the liquid, the pump is regulated in its flow as needed and in the pipes no other control or throttle body is arranged to control the pump flow or the liquid flow.
• the basic idea is also to replace the valves, taps or flaps controlling the flow through the lines in the conveyor system in that the pump promoting the chemical fluid, in particular its speed, is regulated.
• the pump instead of a half-closed valve, the pump to about half their power respectively their speed or to obtain a certain reserve to a little less than half of their power is automatically adjusted or self-adjusting. If a valve were to be closed, this operating situation can be achieved by automatically deactivating the pump or by setting the pump to a minimum of its power or its speed. This has the advantage that the pump does not have to work against one or more closed valves, cocks or valves. Above all, the valves, taps or flaps can be replaced by speed-controlled pumps.
• valves taps or flaps, in particular at the process feed point be provided to completely stop the flow of liquid through the lines in an emergency, however, such valves, faucets or valves do not participate in a control of the pump flow or the flow through the pipelines. This is done exclusively by the need-based adjustment of the power respectively the speed of the pump.
• a replacement of the control and throttle bodies by a regulated engine centrifugal pump leads to the least technical effort to exact and needs-based promotion.
• the control algorithm of the pump (s) allows easy to create control only in the amount as it is actually needed with a high stability, without a rocking and without throttling losses.
