Embodiment Construction
[0060] The waste water lifting device according to the invention has a container 2 which is preferably made of synthetic material. The container 2 has at least one inlet 4 on at least one wall, to which an inlet-side waste water line can be connected, through which waste water flows into the interior of the container 2 . Furthermore, a pump 6 is arranged in the container 2 . The pump 6 is used to pump waste water from the container 2 via a discharge line 7 arranged in the container and a discharge connection 8 provided in the container 2 into a pressure line or a drainage line connected to the discharge connection 8 . An opening 12 is provided on the top 10 of the container 2, in which opening a fill level sensor 14 is arranged. The following will use Figure 2-Figure 5 The liquid level sensor 14 will be further described. The fill level sensor 14 has a sensor housing 16 at its upper end, which is inserted into the opening 12 . The seal 18 bears sealingly against the wall ...

#CMT# # / CMT# The sewage lifting unit a container (2), a pump (6) provided in the container and a liquid level sensor (14). The liquid level sensor in fully closed state is arranged in the membrane container housing which comprises a movable diaphragm. The membrane diaphragm in the interior of the housing comprises a switch which switches ON and OFF the pump. The membrane diaphragm is arranged on the lower side of the diaphragm housing. #CMT#USE : # / CMT# Sewage lifting unit. #CMT#ADVANTAGE : # / CMT# The actual sensor or switch components are arranged in the interior of the diaphragm housing, in which interior of the container with waste water is completely closed, so that the sensor and switches inside the membrane housing are not in contact with the sewage, and the components are protected from contamination and moisture. The membrane housing is detachably connected so that easy installation and easy disassembly for maintenance or repair purposes can be achieved. The reliable working of sewage lifting unit can be achieved with rugged level sensor of high reliability. #CMT#DESCRIPTION OF DRAWINGS : # / CMT# The drawing shows an exploded view of the sewage lifting unit. 2 : Container 4 : Intake port 6 : Pump 8 : Outlet port 14 : Liquid level sensor.
Description
technical field [0001] The invention relates to a waste water lifting device, which has a container, a pump and a liquid level sensor arranged in the container. Background technique [0002] The waste water lifting device is used to lift or draw waste water at the liquid level below the sewer pipe to above the liquid level of the sewer pipe. It is known here that the waste water lifting device has a container into which the waste water to be extracted flows. At least one pump unit is arranged on or in the container in order to pump the waste water from the container to the required liquid level. In order to be able to switch on and off at least one pump as required, a liquid level sensor is provided on or in the container to detect the water level inside the container and to switch on and off the pump according to the water level. [0003] The problem with such waste water lifting devices is that the dirt carried in the waste water can impair the function of the level sens...
