Self-priming pump self-priming time is too long reason and solution

self-priming pump self-priming time is too long, self-priming pump with long time solution

all kinds of self-priming pump self-priming performance are different, often encountered in the use of all kinds of self-priming pump products self-priming pump during the process of imbibition take a long time to absorb water, so the emergency water drainage or use on production water imbibition time is too long delay emergency measures for rush repair and production needs, so it is necessary for us to share about the self-priming pump self-priming time is too long and self-priming pump self-priming time is too long for reference solution:

self-priming pump self-priming time is too long reason is likely to be import pipeline leak phenomenon, slightly the self-priming time too long the self-priming pump solution is filled with water after running for about 5 minutes to ensure that the ear to import pipeline under the quiet environment suspected leak point did listen to breathe in the sound, because the self-priming pump running for a period of time after import can form a negative pressure, point of leak after downtime, such as in the case of negative pressure will reduce the air inhaled into the inlet piping outside the pipeline. Due to self-priming pump inlet piping through long is self-priming pump self-priming time is too long, because import pipeline after long pipe of the air inside a lot, self-priming pump need to import the air pipe smoke after the net import pipe forming negative pressure to suck up water, so the inlet piping is too long will be a lot of self-priming pump and exhaust air takes time to arrange the net, the self-priming time is too long of the solution is to shorten the self-priming pump inlet piping or to switch to my company's vacuum self-priming pump can solve the problem. Due to the inlet pipe has & Omega; Type of bending pipe, especially import the hose, it is easy to appear when solution straight inlet piping. There is a kind of self-priming pump self-priming time is too long because of self-priming water pump outlet pipe ends submerged in liquid in the pump suction air with very demanding, the self-priming pump with long time solution is to put the export pipe ends showing in the atmosphere makes the air discharge quickly. Can also be self-priming pump self-priming by liquid medium temperature caused by cavitation phenomenon in a self-priming pump, this kind of self-priming pump self-priming time is too long the solution is to reduce the temperature of the liquid, or before the start of the pump body inside filled with cold water. Suction pipe diameter is larger than the pump will be cause self-priming pump self-priming time is too long for import pipeline after bigger will reduce the self-priming pump self-priming ability, and self-priming pump of imported matching line is recommended. If you are using a self-priming centrifugal pump products to transport is the beginning of sewage containing particles self-priming time soon, but use after period of time is slow, is likely to be pump body suffered jam phenomenon, the self-priming pump self-priming time is too long the solution can only be replaced self-priming sewage pump products.
