I need to unscramble this statement. I do not understand it ---
Mix auger KW. No efficiency applied. Max load: Max 2021, Min 1294, avg 1721; Min load 690 bph: Max 2288, Min 967, avg 1534. (80 sec time frame including start & stop) No load Max 895, Min 606.
(10) What does "Max load" mean? Is "maximum load" the maximum short time average motor power input when the corn input end of the mixing auger is fully covered with corn (no shortage of input corn), and the auger is moving at its highest RPM that corresponds with the the desired maximum flow rate, 890 bushels per hour, of corn and additives leaving the mixing auger?
(11) If so, then why the huge range of 1290 to 2021 watts?
(12) Minimum load appears to be defined as 690 bushels per hour. I assume this means the auger is running slower to produce the lower flow rate. The motor power input range at this flow rate is 967 to 2288 watts. This is a greater range, lower on the low side and higher on the high side, than at maximum load. Why the greater range?
(13) Would not auger RPM be a better measure of flow rate than motor power input?
(14) The items referred to as tanks have level switches at 486 bushels (high level) and 426 bushels (low level), 60 bushels less than full, and these limit switches are input signals to the VFD control. Is this correct?
(15) There are two 486 bushel tanks. Are these tanks simultaneously filled? Are there high and low level switches in both tanks? Are these cooking tanks?
(16) With no product, corn and additives, in the mixing auger is the mixing auger motor power input 606 ton 895 watts?
