Magnetic flap thermometer replacement pressure transmitter measuring water level technical transformation of the tail pipe

For pressure transmitter measured during the time of draft tube, the defects of errors measured value, the pressure transmitter operating conditions and the actual situation to carry on the preliminary analysis, think that by using the principle of communicating vessels, above the total suction pipe installed a set of float type water level switch, so that both can intuitively reflect the real-time water level, and can guarantee safe and reliable operation of the pump, the position of the float switch can be decorate, according to the actual work level using the float switch to control the amount of normal start-up of water pump. The search for various information and consulting related equipment manufacturers, after decided to repair the drainage system to increase a set of water level measuring device, specific solutions for: above the total suction of the pump installed a set of magnetic flap thermometer, as shown in figure 2.

it is using the principle of the by-pass pipe structure, the dominant tube liquid level and liquid level height consistent within the draft tube, according to the Archimedes theorem, the magnetic float in a liquid produced by gravity and buoyancy balance, when the water level in draft tube elevator, the float thermometer led tube also lift, driven by permanent magnet magnetic FGC within the float indicator inside the frame pointer, when the liquid level rising or falling, the flap indicator turned from white to red, or turn from red to white, the color of the indicator to change height is measured the actual height of the water level, so as to realize the field of liquid level indicator, visual tail pipes for operators of water level in real time. Installed on the wall outside of the thermometer magnetic memory switch, can be set up more, sliding v position, provided the amount of liquid level switch alarm function. At the top of the device installed an automatic exhaust, when leading tube liquid level rise automatically exhaust, declined to fill gas on time.

installation device scale. , corresponding ground elevation is EL. 40. 0 m。 Float switch set five water action value, repair water low switch alarm value corresponding to the height of 40. 3m; To stop all maintenance pump switch, and the corresponding height of 40. 5m; Pump on primary repair of switch, and the corresponding elevation is 40. 9m; Pump on maintenance of main pump switch quantity, and manually start the pump, and as the high water level alarm, giving the upper machine of the elevation is 41. 1 m to 41. 2 m, two parallel access switch quantity. All switch traffic to PLC respectively, as shown in figure 3. Uc2 magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

water level 40. 9米,41岁。 1 m, 41岁。 2 m of the switch quantity have increased since the holding function; Water level 40. 3 m, 40岁。 5 there is a decrease in the amount of switch in the keep. Retain the pressure transmitter in the process of technological upgrading wiring. Keep its analog give PC, only for display, but cancel the pressure transmitter in the repair drainage system logic control maintenance pump start-stop function, logic increased by the float switch to control the maintenance of water pump start-up process.

due to the magnetic flap thermometer interface flange installation place with the water valve, when you don't need a pump turbine drainage at ordinary times repair, the valve closed, may, when necessary, through the device at the bottom of the drain valve emptying the water from the thermometer led tube.
