Sewage pump water time method

Everyone in the use of sewage pump, the need for its water time have a certain understanding of the following sewage pump manufacturers for everyone to introduce in detail, interested in this knowledge friends do not miss.
1, the sewage pump is based on the standard atmospheric pressure derived from the standard, when the test pressure is not a standard atmospheric pressure, the calculation formula should be amended. This formula is not applicable when the height variable in the estimated formula is within the range of (7-D / 2/7). However, since the height of (7-D / 2) to 7 is relatively small, The pump also has a certain exhaust effect, so this process is very short, the overall calculation results have little effect.
The results of water diversion test of three kinds of sewage pumps show that the calculated results are in good agreement with the measured data, and the error is less than 4%. Therefore, the derivation of the estimation formula is successful, and it is practical to design a reasonable sewage pump for more accurate determination of the parameters of the diversion pump.
3, therefore, the sewage pump water time is very strict, the flow of 50L / s the following pump, water time does not exceed 35s; flow 80L / s or more pumps, water time does not exceed 80s.
Everyone in the understanding of this knowledge, if there are other sewage pump can not understand the place at any time from our website to understand.
