Description

Tester of level controller for drive control of draining tank sump pump}

The present invention relates to a tester of a level controller for controlling driving of a sump pump, and more specifically, to an electrode level controller for controlling the driving of a sump pump that is widely installed and used in industrial sites and power generation facilities, and to a tester of a level controller for controlling a driving of a sump pump to enable convenient testing and inspection of the sump pump.

In general, “a tester of a level controller for controlling a pump in a sump pump” has already been widely disclosed, and a detailed description thereof will be omitted.

The above-mentioned "water level detector" is a water level detection device divided into multi-levels that can detect a constant level without movement of the operating part. It minimizes production cost to lower production cost, minimizes detection and operation errors to increase reliability of water level detection, minimizes the possibility of failure, and makes installation and management easy. In the case of the rod type, it is inconvenient to test and check by immersing it in water in the pit, and it is inconvenient to test by connecting test connection lines directly to each electrode.

At this time, when testing by immersing in water, if there is not enough water in the drainage tank connected to the drainage pump, there is an inconvenience of waiting until it is completely filled, and an inconvenient problem of having to take an unstable working posture as the area around the entrance of the drainage tank is narrow.

In addition, there is a problem in that the operator feels inconvenience during testing and inspection because the same operation of releasing and picking up the tongs for each level must be repeated during the test of the electrode.

[Patent Document 0001] Patent Publication No. 10-2012-0101964 "Water level sensor" (Announcement 2012.09.17.)

The present invention was invented to solve the above problems, and its purpose is to conveniently test and check the electrode level controller and the sump pump for controlling the driving of the sump pump, which is installed and used in many industrial sites and power generation facilities.

Another object of the present invention is to use a level controller tester connected to an electrode level sensor with a tester connection line and a lead-out connection line so that inspection and testing can be easily performed only by operating the first, second, and third switches, which are toggle switches. It is to shorten the inspection of the electrode level controller and the sump pump and improve the convenience of inspection.

In the present invention for achieving the above technical problem, in the level controller tester provided to check the level controller for controlling the driving of the sump pump after determining the signal of the electrode level sensor, the level controller tester connects a plurality of test connection lines having male type receptacle lugs and tongs installed at both ends, respectively, so that they can be connected to each electrode level sensor for electrically applying a water level signal, and a female type receptacle lug connected to an end so that it can be coupled to and connected to the test connection line during the test of the level controller. A plurality of outgoing connection lines and the outgoing connection line are provided on one side, and a toggle switch unit provided as first, second, and third switches and installed in the test switch box to apply electrical signals to the electrode level sensor, and a control unit built in the test switch box. It is characterized in that it is possible to check whether or not there is a test abnormality through blinking of a corresponding lamp formed in the state display lamp unit of the level controller through the electric signal of the control unit.

The toggle switch unit is composed of first, second, and third switches to be exposed on the test switch box, and a common terminal is connected to one of the lead-out connection lines. The third switch allows an electric signal to be applied to a third level sensor of an electrode level sensor that detects the water level in the uppermost part of the tank. An electric signal is applied to the first level sensor of the rod level sensor, and the common terminal is characterized in that the electric signal is applied to the fourth level sensor of the electrode rod level sensor that senses the water level of the lower layer.

When the first, second, and third switches among the toggle switches are all off, the power lamp and the lower alarm lamp among the status display lamps of the level controller are turned on, and the high alarm lamp and the control lamp are blinking to indicate that the sump pump is off. When only the first switch and the second switch are on, only the power lamp and the control lamp among the status display lamps of the level controller are turned on, and the high alarm lamp and the lower alarm lamp are blinking, so that the sump pump is turned on. It is characterized in that the test of the level controller is easily performed because it is made to be confirmed.

According to the tester of the level controller for controlling the driving of the sump pump of the present invention, it is possible to conveniently test and inspect the electrode level controller and the sump pump for controlling the driving of the sump pump, which is widely installed and used in industrial sites and power generation facilities.

In addition, by using a level controller tester connected to the electrode level sensor with a tester connection line and a withdrawal connection line, inspection and testing can be easily performed only by operating the first, second, and third switches, which are toggle switches. There is an effect of shortening the inspection and improving the convenience of inspection of the sump pump.

In addition, by developing a level controller tester for the level controller provided in the sump pump, it is possible to perform the inspection and testing according to the manual, thereby making the inspection and testing work convenient.
