Magnetic float level gauges are now used in many places. For example, because the pump can be opened and closed, a lot of manpower can be saved. Since many people do not know the principle of control, the following editor will explain how the magnetic suspension level gauge controls the pump.
How does the magnetic float level gauge control the pump? In order to prevent a pump from restarting repeatedly, the pumps are put into operation in a cycle, first running and then stopping, and running first and then stopping. When one pump stops due to a failure, the other pump automatically goes into operation. The possibility of realizing the float level switch to control the start and stop of the pump. After the water supply pump controlled by the float switch is changed to an ultrasonic level gauge, no other investment is allowed except for the addition of an ultrasonic level gauge. In addition, there is no cost to change the software, this part of the investment does not increase, and it does not have any impact on computer monitoring. After the transformation, the cost of float switches, relays, PLC modules and multiple cables and the occupancy of PLC bytes are reduced, and the original design ideas are fully reflected, and the abandoned automatic control parts can be fully utilized. After the automatic control is realized, the downtime and number of pumps are arranged scientifically and reasonably, which avoids human error and improves the safety, reliability and stability of operation. How does the magnetic float level gauge control the water pump Magnetic level gauge The magnetic float type liquid level gauge is installed on the extension pipe outside the water tank, and the liquid level inside the water tank can be clearly understood by the inverted indicator. It is also possible to install a magnetic switch on the outside of the bypass pipe as an electrical contact signal output, or a liquid level transmitter of the device for remote liquid level signal transmission and liquid level control. The level gauge is a reliable and safe instrument. The water level gauge works based on the principle of buoyancy and the principle of magnetic coupling. When the liquid level in the measured container rises and falls, the float in the main pipe of the liquid level gauge also rises and falls, and the permanent magnet steel in the float is transferred to the on-site indicator through magnetic coupling, so that the red and white flipping columns are rotated by 180. When the liquid level rises, the reverse column turns from white to red; when the liquid level drops, turn the pipe string over and turn it into white, and the red and white boundary position of the indicator becomes the actual height of the medium liquid level in the container, and the liquid level can be indicated. Magnetic level gauge installation The level indicator of the magnet plate is installed on the outside or above the oil tank. In order to indicate and control the sealing form in the oil tank, a discharge valve can be installed as needed. It can accept custom-made liquid level control instruments connected with flanges. The indicator is made up of magnetic-colored plates. The magnetic ball in the trachea of the main body rises with the liquid level. After the color plates are reversed, the height of the liquid level can be displayed. It is also possible to install a magnetic switch and a remote transmission transmitter on the air pipe of the host to output switch signals and analog signals. It is suitable for high temperature, high pressure, corrosion resistance, etc. It can be displayed on site and operated remotely. The main pipe adopts seamless steel pipe, and the connecting pipe adopts pull hole welding, and there is no internal scar. The installation method can choose side installation and top installation, and the lower end of the main body is sealed. How does the magnetic float level gauge control the water pump How does the magnetic float level gauge control the pump? After reading this, I think you know the principle of control. If you want to buy a good magnetic float level gauge, please go to the instrument manufacturer of Huikeda to see. You will be satisfied.
