直销德国PVV42-1X/113-060RA15UUMC力士乐叶片泵

力士乐叶片泵故意障原因加以分析
1）叶片泵有些用户水泵启动前未灌满足够水；看上去灌水已从放气孔溢出，但未转动泵轴交空气完全排出，致使少许空气还残留进水管或泵体中。
2）叶片泵接触进水管水平段逆水流方向应用0.5%以上下降坡度，连接水泵进口一端为较高，不要完全水平。向上翘起，进水管内会存留空气，降低了水管和水泵中真空度，影响吸水。
3）叶片泵填料因长期使用已经磨损或填料压过松，造成大量水从填料与泵轴轴套间隙中喷出，其结果是外部空气就从这些间隙进入水泵内部，影响了提水。
4）进水管因长期潜水下，管壁腐蚀出现孔洞，水泵工作后水面不断下降，当这些孔洞露出水面后，空气就从孔进入了进水管。
5）进水管弯管处出现裂痕，进水管与水泵连接处出现微小间隙，都有可能使空气进入进水管。 　水泵转速过低
1）人为因素。有相当一部分用户因原配电动机损坏，就随意配上另一台电动机带动，结果造成了流量少、扬程低抽不上水后果。
2）传动带磨损。有许多大型离水泵采用带传,因长期使用,传动带磨损而松也,出现打滑现象，降低了水泵转速。
