| Fault | Reasons for 2SK loop vacuum pump | 2SK waterring vacuum pump |
| There's not enough gas. | 1. Too wide a gap | 1. Adjustment gap |
| 2. Leakage at filling | 2. Tightening or replacing fillings | |
| 3. High ring temperature | 3. Increasing water supply | |
| 4. Leakage of pipeline systems | 4. Tighten French bolts, replace gaskets or weld cracks, etc. | |
| Lower vacuum. | 1. Pipeline systems | |
| One French connection leaks. | One, one screw the flannel bolt or replace the gasket. | |
| 2 pipes have cracks. | 2 Welding or replacement | |
| Water rings pumps | ||
| 1 filling leak | 2 and 1 pressure fillings to replace new fillings | |
| There's too much gap between two wheels and the side cover. | 2 Replace gasket adjustment gap | |
| It's three years old. | 3. Reduced water temperature | |
| 4 insufficient water | 4 Increase in water supply | |
| 5 parts rubbed and heated up, resulting in an increase in the temperature of the water ring | 5 Adjustment or re-installation | |
| Vibration or sound | 1. Fence loose on the ground | Tightening the ankle bolts |
| 2. Alien grinding in pumps | 2. Stoppump inspection to extract aliens | |
| Three, leaves fall. | 3. Replacement of leaves | |
| Air erosion | 4. Open inhaler valves | |
| Axis fever. | 1. Insufficient lubricants | 1. Check for lubrication, refuelling |
| Overstretched pressure of filling | 2. Release appropriate filling caps | |
| 3. No sealed water or insufficient | 3. Supply of sealed or increased water | |
| 4. The bearings or axes or bearings are over-heavy, resulting in friction between the ball and the inner and inner circle. | 4. Adjustment of the bearings with the bearings or bearings | |
| Hard to start. | 1. Rusty inside the pump after a prolonged shutdown | 1. Rotation of leaf wheels several times with hand or special tools |
| Pressure on fillings | 2. Lemon pine filling caps | |
| 3 and foliage between the wheel and the pump | 3 Re-installation and adjustment |
