With the continuous deepening of the internal management system reform of the enterprise, the refinement of Centrifugal Pump fault management and maintenance has become a problem that people pay more and more attention to. At present, finding the technology and method of centrifugal pump fault maintenance has become a new research topic. Doing a good job in the daily maintenance of centrifugal pump equipment and improving the protection mechanism are important ways and means to improve the service life and efficiency of mechanical equipment.
Non-Clogging Centrifugal Pump
Analysis of common failures of centrifugal pumps
During the operation of the Non-Clogging Centrifugal Pump, because the management personnel did not pay attention to the daily management and maintenance work, as the service life goes on, the centrifugal pump will inevitably have various failures, such as leakage, noise, overload or excessive current. The flow rate is insufficient or the head is too low. These are some common problems in the daily operation of centrifugal pumps. The following will focus on the analysis and research on the leakage problems of centrifugal pumps.
Analysis of leakage failure problem
Centrifugal pump leakage is divided into two types: temporary and permanent. A short-term centrifugal pump leakage can evacuate the fuel tank, clean it and use it, so that the leakage problem can be eliminated.
In addition, it can also be divided into static and dynamic leakage. This type of leakage is common in the static test after the mechanical seal is installed to observe the leakage. If the leakage problem is not obvious, it can be preliminarily judged that it is due to the failure of the hyperactive environment sealing O-ring. During operation, there are problems with the friction pairs of the moving and static rings. The technicians should check the parts prone to leakage according to their own practical experience, and carry out inspection and maintenance work. Leakage generally occurs on parts such as manual cranking. If no abnormality is found in this regard, it can be judged that it is due to a malfunction of the static ring seal O-ring.
Another situation is the obvious leakage problem. During the operation of the centrifugal pump, the equipment leakage problem is serious, causing the production system to fail to operate normally. When static leakage occurs, technicians should consider whether the friction pair is normal. Once the friction pair is damaged and loses balance, the entire centrifugal pump will not work normally, which will cause friction between the machines and scratches. Centrifugal pumps The O-ring in the middle will become tighter due to scratches and vibrations, and eventually the spring on the O-ring cannot be adjusted automatically. At this time, the ring shaft will float upwards, causing leakage failure.
