Many users in the use of self-priming pump may encounter self-priming pump is not the case of water, the emergence of this situation caused great distress and inconvenience to the user, but also may delay the production And the use of equipment, then the cause of this situation may have what? How should users solve? Self-priming pump is not on the water how to do 1, the body without liquid or lack of stock solution: to add enough storage fluid; 2, inhalation pipeline leakage :: elimination of pipeline leakage; 3, the voltage is too low: adjustment Voltage; 4, suction stroke is too high or suction pipe is too long: reduce suction or shorten the pipeline; 5, mechanical seal leakage is too large: repair or replacement; 6, pump body or imported pipe filter debris clogged with debris : Check and clean up the blockage; 7, the impeller is damaged or worn: replace the new impeller; 8, the outlet pipe is not installed properly Elbow too: pipe into a N-shaped pipe too much recommended to install automatic exhaust valve at the highest point; 9, the three-phase motor wiring is reversed: interchange two phases; 10, self-priming pump backflow hole is blocked caused soda can not be separated: check and clean out; self-priming pump is not on the water may have other reasons, but more than 10 Point is more common situation, users can experience in such cases can learn from. With the increasing use of self-priming pumps, the probability of product problems may also increase with each passing day, but we believe that with the joint efforts of researchers, merchants and users, we will certainly be able to overcome these problems so that we can make the most of these types of products Product value and significance.
