Volute casing mixed flow pumps are suitable for transporting cold water or other liquid substances with physical and physical properties similar to water. The temperature of the liquid being transported should not exceed 50℃. They are widely used in various applications such as agricultural irrigation, industrial production, and regional water supply and drainage. The construction of the volute casing mixed flow pump is simple, reliable, and easy to maintain. The pump performs well, with a smooth output power curve, a broad application range, low shutdown output power, and good cavitation performance. The application head of the pump is typically between 3 to 15 meters. The外壳 of the volute casing mixed flow pump is generally large, occupying more space, but the aspect ratio is usually low. There are two types of volute casing mixed flow pumps: horizontal and vertical. Horizontal pumps can be further divided into horizontal, vertical, and oblique configurations.
Seven key reasons causing the rotation obstruction of mixed flow pump gear pumps
Impeller pump gear pumps may experience resistance during rotation, leading to issues such as stiffness or jamming, significantly affecting the actual expected performance for many impeller pump consumers. Here, we introduce seven important reasons for the resistance encountered during the rotation of impeller pump gear pumps.
1. Gear pump shaft bearing clearance or radial clearance is minimal. Solution: Ensure thorough mechanical and electrical maintenance adjustments on all aspects.
2. Assembly error. The reason is that the manufacturing standard for the two bore holes of the gear pump is not the assembly standard; the nut should be inserted first, followed by tightening the screw. Otherwise, the casing impeller pump won't rotate. Solution: The nut should be inserted while rotating the gear pump and the screw should be tightened. Finally, use a pilot drill to bore the holes and insert the nut.
3. There is debris inside the gear pump. Solution: Split to remove the uncleaned material.
4. Gear pump internal parts not degaussed. Solution: All parts of the gear pump must be degaussed before assembly.
5. Planarity deviation between gear pump and diesel engine coupling. Solution: The planarity of the gear pump should be ensured within 0.00mm.
6. The China National Petroleum Corporation's import and export channels are blocked. Solution: Clear out the uncleaned items.
7. Poor quality of needle roller sleeves or cracked needle rollers. Solution: Inspection or disassembly.
