However, during operation, a number of problems may arise, including abnormal vibration, insufficient flow rate, bearing overheating, etc. <a href=\"https:\/\/www.longgangpump.com\/ru\/\">Yantai Longgang Pump Industry Co., Ltd.<\/a>\u00a0(hereinafter referred to as Longgang Pump Industry)\u00a0responds to these common faults by offering a number of effective and dependable solutions that are based on years of technical accumulation and industry experience.<\/p>\n<h2>Common Problems of Centrifugal Pumps and Their Solutions<\/h2>\n<h3><strong><b>1. The pump <\/b><\/strong><strong><b>cannot<\/b><\/strong><strong><b> start or operate abnormally<\/b><\/strong><\/h3>\n<p>Potential causes: power outages, motor damage, impeller jamming, and the inlet valve not being opened.<\/p>\n<p>Solutions:<\/p>\n<ul>\n<li>Check the insulation performance of the power supply and motor to ensure stable voltage.<\/li>\n<li>Clean foreign matter in the pump chamber to prevent impeller blockage.<\/li>\n<li>Check whether the inlet and outlet valves are fully open to avoid air binding.<\/li>\n<\/ul>\n<p>Advantages of the Longgang Pump Industry:<\/p>\n<p>High-performance motors and anti-stuck impeller design are used to reduce the startup failure rate.<\/p>\n<h3><strong><b>2. Insufficient flow rate or head<\/b><\/strong><\/h3>\n<p>Potential causes: impeller wear, excessive clearance of the sealing ring, mismatched rotation speed, and leakage of the inlet pipeline.<\/p>\n<p>Solutions:<\/p>\n<ul>\n<li>Replace the worn impeller or adjust the seal ring gap.<\/li>\n<li>Check whether the pump speed meets the design requirements.<\/li>\n<li>Check the pipeline system to ensure there is no leakage or blockage.<\/li>\n<\/ul>\n<p>Technology of Longgang Pump Industry:<\/p>\n<p>Use high chromium alloy impeller and precision casting technology to extend the service life of the impeller and improve pump efficiency<\/p>\n<h3><strong><b>3. Excessive vibration or noise of the pump body<\/b><\/strong><\/h3>\n<p>Potential causes: damaged bearings, unbalanced rotors, unstable foundation, and cavitation.<\/p>\n<p>Solutions:<\/p>\n<ul>\n<li>Make sure the bearings are properly lubricated and replace any damaged ones.<\/li>\n<li>Adjust the dynamic balance once again.<\/li>\n<li>To lessen resonance, reinforce the pump base.<\/li>\n<li>Optimize the suction pipeline&#8217;s design to prevent cavitation.<\/li>\n<\/ul>\n<p>Solutions of Longgang Pump Industry: Shock-absorbing brackets and high-precision bearings are included to enhance operating stability and successfully lessen noise and vibration.<\/p>\n<h3><strong><b>4. Overheating of bearings or mechanical seals<\/b><\/strong><\/h3>\n<p>Potential causes: insufficient lubrication, failure of the cooling system, seal failure, and poor alignment.<\/p>\n<p>Solutions:<\/p>\n<ul>\n<li>Regularly add or replace lubricating grease.<\/li>\n<li>Check whether the cooling water system is unobstructed.<\/li>\n<li>Replace damaged mechanical seals to ensure installation accuracy.<\/li>\n<\/ul>\n<p>Technology of Longgang Pump Industry:<\/p>\n<p>Use imported high-temperature resistant bearings and double-end mechanical seals to improve wear resistance and high temperature resistance.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter size-full wp-image-3075\" src=\"https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/system-of-centrifugal-pumps.png\" alt=\"System of Centrifugal Pump\" width=\"641\" height=\"430\" srcset=\"https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/system-of-centrifugal-pumps.png 641w, https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/system-of-centrifugal-pumps-300x201.png 300w, https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/system-of-centrifugal-pumps-600x402.png 600w\" sizes=\"(max-width: 641px) 100vw, 641px\" \/><\/p>\n<h2>Technical and Strength Advantages of\u00a0the\u00a0Longgang Pump Industry<\/h2>\n<ul>\n<li>Advanced manufacturing technology: To optimize the hydraulic model and increase pump stability and efficiency, CAD\/CAE simulation design is used.<\/li>\n<\/ul>\n<p><img decoding=\"async\" class=\"aligncenter size-large wp-image-3077\" src=\"https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/advanced-centrifugal-pump-manufacture-1024x690.png\" alt=\"Advanced Centrifugal Pump Manufacture\" width=\"800\" height=\"539\" srcset=\"https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/advanced-centrifugal-pump-manufacture-1024x690.png 1024w, https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/advanced-centrifugal-pump-manufacture-300x202.png 300w, https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/advanced-centrifugal-pump-manufacture-768x518.png 768w, https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/advanced-centrifugal-pump-manufacture-600x404.png 600w, https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/advanced-centrifugal-pump-manufacture.png 1043w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/p>\n<ul>\n<li>High-wear-resistant materials: To prolong the service life, important parts such\u00a0as\u00a0impellers and pump casings are made of stainless steel, high-chromium alloy, and other materials.<\/li>\n<\/ul>\n<p><img decoding=\"async\" class=\"aligncenter size-large wp-image-3076\" src=\"https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/parts-of-centrifugal-pump-768x1024.png\" alt=\"\" width=\"768\" height=\"1024\" srcset=\"https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/parts-of-centrifugal-pump-768x1024.png 768w, https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/parts-of-centrifugal-pump-225x300.png 225w, https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/parts-of-centrifugal-pump-600x800.png 600w, https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/parts-of-centrifugal-pump.png 960w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><\/p>\n<ul>\n<li>System of intelligent monitoring: Predictive maintenance is accomplished through the provision of remote monitoring and fault early warning capabilities.<\/li>\n<\/ul>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-3078\" src=\"https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/intelligent-system-of-centrifugal-pump.png\" alt=\"\" width=\"827\" height=\"551\" srcset=\"https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/intelligent-system-of-centrifugal-pump.png 827w, https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/intelligent-system-of-centrifugal-pump-300x200.png 300w, https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/intelligent-system-of-centrifugal-pump-768x512.png 768w, https:\/\/www.longgangpump.com\/wp-content\/uploads\/2025\/05\/intelligent-system-of-centrifugal-pump-600x400.png 600w\" sizes=\"(max-width: 827px) 100vw, 827px\" \/><\/p>\n<ul>\n<li>Thoughtful after-sales system: To guarantee clients&#8217;
