Can anyone report me how to oral exam and charge the capacitor within the control box for my submersible sea pump? I have a 220v, 3/4 hp submersible okay i just installed for...
I have a 220v, 3/4 hp submersible okay i just installed for a moment while back. Also installed a control box of the right specifications for it. Both are used however. After the initial installation, I didnt own the pressure tank hooked up all the same, so i just closed the major shut off spigot and turned the power on to it for a couple seconds to see if it would come on. It did. So I shut it rotten until I got the pressure container installed and everything hooked back up a couple weeks subsequently. I then tried to turn it on and zilch happened. I put a voltmeter on the capacitor and it showed a reading, but that reading be less than the chart on the inside of the box stated that it required. I verified that I be getting power through the pressure switch and coming into the box. It actually read almost 260v instead of 220. I dont enjoy a capacitor tester. Can someone please tell me how I can shift about conducting tests it and tell me how to charge it correctly in the past putting it back surrounded by the circuit? I'd appreciate it
Sears sells a cheap multi meter that read MFD look for one with a Uf mount. Again always hold power off remove the wires connected to the capacitor short the two connections near a screwdriver then experiment.
Id be more concerned about a contest of the control box to the pump than measuring a capacator. Those control panel for submerged pumps are made by the millions, for example, Franklin Electric in Indiana make about a million a year.
If you own a used box, get rid of the older box when you install a new pump and put the exact box as specified for the submergable.
What you stipulation is a voltage check across the center tap and the power side of the capacator when the circuit is surrounded by the start mode. That voltage is only on for give or take a few a 3 second period so it is deeply hard indeed to catch a reading. Its that voltage and time setting as a combination that determine the proper starting of that pump. The time of course, is controlled by the electronic switch inside the circuit box. The combo of those two determines the starting of that pump in the past capacator is switched off and the pump later runs on reguar supplied 220V. All this is much to difficult to measure contained by an in home environment, its the responsibility of a labarabory equipped to do so . So with that said. Install a exotic control box and and leave it at that.
On pump failure, it almost 100% due to two problems, on is that box and the electronic switch inside of it that makes and breaks the capacator leg of the power and the second, is the reality that Lightening strikes the pump piping or wiring.
In my nouns we have greatly of lightening strikes so around the permieter of the pump I have buried a copper ground telecommunication at a radius of about 30 foot and 4 feet open. This has stopped the problem of lightening strikes and the current pump within there is over 20 years antiquated.
Answers: The only bearing to properly test a capacitor is to hold a meter that reads surrounded by micro farads.... but in a pinch you can use the ohm reading on your current meter and tryout the capacitor. The capacitor should have two fittings on the top, place one of the lead on each of the fittings. The reading on the meter should any go up or down. Remember which it does and afterwards reverse the leads.... if the reading on the meter very soon does the opposite.... you most credible have a well-mannered capacitor. (Example Red lead on fitting A and black organize on fitting B the Ohm reading starts at 0 and begins going up .... presently put the red lead on B and the black organize on A and the reading should start at a higher pro and come down) If this does not happen you hold a bad capacitor. If the panama is bad you will want to replace it next to an identical type and size capacitor. If it have a metal case it is a run capacitor, if it have a fiber case it is a start capacitor, also the micro farad (uF) and the voltage should be impossible to tell apart or you may get some hasty results. Good Luck Also, you do not have to recharge a capacitor... it will store the voltage it desires when you power it up..... Also be careful, these things store voltage.... steal a screwdriver and short the fittings together before you try to assessment it!!!
