Single-stage centrifugal pump users should know that the single-stage centrifugal pump is an important member of the centrifugal pump, the pump drive is mainly through the extension of flexible coupling connected with the motor, the pump through the clockwise Direction of rotation. Single-stage centrifugal pumps, like many other pumping equipment, occasionally naughty, and when it is too naughty, will have a serious impact on the production work, which is what we often say single-stage centrifugal pump failure. So single-stage centrifugal pump prone to failure what? Is there any suitable solution to the problem? Single-stage centrifugal pump failure analysis and solutions 1, the mechanical seal leakage; solution: replace the mechanical seal; 2, the seal at the Department of serious water leakage; solution: cooling water valve opening, reducing the cooling water valve opening; seal The seal ring is damaged, replace the seal ring. 3, the pump body vibration is too large; solution: check the pump shaft and motor coaxiality and adjust, check the bearings and replace, check the anchor bolts are loose; 4, a sudden drop in flow, outlet pressure decreases, impeller or serious corrosion wear; The solution: clean or replace the impeller; impeller mouth ring wear and tear, the gap is too large, replace the mouth ring; to solve the equipment failure is kind of understanding of the equipment is a very good way, through the above analysis, we have a single-stage centrifugal pump deeper understanding. The use of each product can not be flawless, even in the perfect product, in the course of the use of more or less there will be a situation. For those problems that may occur or have emerged, we can not escape, to face directly, not only to better use of the product, but also to provide greater help to our productivity, so that when a single-stage centrifugal pump failure When we try to find the appropriate solution.
