Thus, if the voltage in the network disappears, the relay turns off and the entire system is powered by a buffer battery. Dampness, of course, did not go anywhere, mold began to actively develop. And so for the second month. The length of the tube is 4 meters and all these 4 meters up the pump pumps briskly, while the water outlet, in my opinion, is at least 2 l / min. Hence the idea to put a small water pump. There was no 12V power supply for more than 1.25A on the farm, and I didn’t want to remove the battery from the car, sorry, I didn’t have a multimeter at hand either, so I did the tests as best I could. In the name of salvation, every morning the water was pumped out by a large 380-volt drainage pump, the ritual lasted about 15 minutes with the cable and hose unwinding and rewinding. A little later, a real 2.5A power supply will be added to the box with the board, ordered on Ali from disassembly for a penny. The minimum voltage for unwinding is 3 volts, but the supply is very small, but in this way you can adjust the pressure. The pump does not draw water onto itself, that is, it must be immersed. Every spring, during the period of snow melting, we are faced with the problem of flooding the cellar in a private house. Can operate as normally open or normally https://tonaton.co.ke/c_heavy-equipments-machinery closed. The value in seconds from 1 to 999 is set on the board. After the next pumping out, I measured the speed of water inflow – about 10 liters in 10 minutes. Making drainage in the cellar.

And this is what it looked like every morning from mid-September until mid-November. The float reed switch is also good. The shoulder blades withstood a palpable compression of the fingers. Here it is: But this is completely different The description on the site is incorrect, but I read the reviews and decided to take it, https://tonaton.com/s_254-flat-irons since it fit better in terms of characteristics at the same price. Then I checked the water supply with a rise of 1.2 meters and with the same tube length of 4 meters – it turned out to be a supply of 7 liters per minute, which is also very good. And as you know, Belarusians are very fond of bulba, and it is very painful for us to watch how the harvest of hundreds of kilos of potential potato pancakes disappears. The choice was between membrane and centrifugal. The relay is decoupled from the board, so 220V consumers can also be connected, but I would not advise connecting a load of more than 1kW, although 10A is declared. So during the day the floor began to dry out (the photo shows), places of water seepage appeared, to prevent evaporation, these wet places were then covered with a film. But this year, the weather in Belarus surprised with prolonged rains – the cellar was https://jiji.ng/20-tables/modern flooded immediately after the potato harvest, and someone did not even have time to dig it out. Average electricity consumption is negligible, about 3W/hour. At the inlet of the pump, I hastily made an inlet filter from a jar of isotonic, drilling holes and wrapping it with spunbond. The bottom line is this: as soon as the water in the pit runs up to the float, the float closes and the signal goes to the board, the relay closes on the board and the pump turns on for N seconds, after which it turns off until the water closes the level sensor again. For uninterrupted operation in case of failures in the supply of 220V mains, you can additionally install a battery and supply a relay with 12V coil power. connect the battery to a normally closed contact, and the power supply to a normally open contact and power the relay. I wanted to order a small membrane for 2.5 l / min, but then I got caught on the KCASA KC-JK505 banguda. There is no dangerous voltage, performance with a margin, I think it will survive more than one flood. When disassembling the pump, I was surprised, for such a price it was made very high quality. At
Noisy when running dry, calms down with water. The disadvantage of this option is the additional consumption of the relay (0.3-1 watt). Not suitable for pumping oil out of a car. Thus, the circuit turned out to be working, the pump turns on every 10-13 minutes and runs for 90 seconds as set on the board (pit pumping time). To do this, you need to remove the retaining ring and turn the cylinder over, the magnet is not in the center there. It was decided to install a float reed switch and a time delay relay as an automatic control. I conclude that the real characteristics, adjusted for resistance, are close to those declared.
The rotor is “wet” brushless, the pump itself is submersible. There is a mode memory. P.S.2 I am waiting for an ozonizer 10gr/hour with fasttech, I will try to treat the cellar and not only from the overgrown mold. There was little sense from this procedure – in a day the water ran to the previous level, one and a half cubic meters offhand. In the summer I will think about waterproofing. The tube was only with an inner diameter of 8mm, and the pump fitting was about 10mm, I dipped it in boiling water and everything fit.

Mini pump KCASA KC-JK505. So the idea was born to make automatic drainage. The pump just hangs on the hose, I didn’t fix it in any way, I just crushed the tube with a brick, and set the pump itself horizontally 5 cm from the bottom so that the sand would not pick up. So now it looks like the old powerful workaholic-drainer can rest. If at the end of the timer, the float is still closed, then the relay turns off for a fraction of a second and turns on again, and the timer starts counting again.
