China wholesale sewage pumps

In addition, China wholesale sewage pumps, use a small displacement to pump water first when starting the pump, so that the main line pressure rises slowly, and pressure fluctuations can also be reduced. Mainly because of the different sizes of balls, poor hardness, large clearance, etc.

If the bearing gap is too large, it is easy to loosen the shaft, so the bearing gap should be adjusted in time. Points to note during maintenance In the process of maintenance, you should strictly follow the regulations and pay attention to the following points.

The air bag is easy to form during operation, which causes the pipeline pressure to fluctuate. Bearing 'running to the outer edge' Due to the poor assembly quality of the bearing, after a long time operation of the pump, the bearing 'running to the outer edge' phenomenon will occur, causing the temperature of the bearing to rise, noise and rotation. Bearing problems 1. The more the number of replacements, the larger the hole, resulting in failure to tighten.

There should be no more than 3 gaskets in one place, otherwise it is difficult to ensure the smooth operation of the pump. Second, the rubber ring, plum rubber, etc. The solution is: (1) Weld the bearing bracket with a layer of metal, then turn it to a suitable size, and reassemble; (2) If the bearing gap is large, thin the copper skin can be used to make the static fit of the bearing outer edge meet the requirements value. 3. In order to eliminate this phenomenon, a negative pressure gauge is installed at the inlet of the pump to observe the negative pressure changes at any time, so as to accurately determine the changes in the suction pipeline and clean the bottom valve and filter in time.

The solution is to fix the pump first, then align it, then cut off the flanges on the inlet and outlet pipes, make them align with the flanges on the pump body, install the connecting bolts and tighten them, and then connect the inlet and outlet pipes Connect with the flange. Therefore, if the bearing is found to be abnormal, it should be stopped and replaced in time. When the pump is running, the fluid passage is not smooth, resulting in hydraulic shock and vibration of the pump. Even if the air is discharged completely when the pump is turned on, it is difficult to clean it. 2.

Submersible Sewage Pumps Manufacturers

Long-term overload operation of the engine and late fuel supply time, etc.2020-03-30The electric diaphragm pump is driven by a cycloid pinwheel reducer, and the double diaphragm is driven to reciprocate through the crankshaft slider mechanism, so that the volume of the working chamber changes alternately so as to continuously suck and discharge the liquid. After zui, check whether the exhaust valve of the radiator cover is invalid.

The electric diaphragm pump cannot start or moves slowly. 1. Suddenly high water temperature. At this time, pay Submersible Sewage Pumps Manufacturers attention to check whether the plane of the body and the joint surface of the cylinder head are seriously warped and deformed. If the liquid delivered does not match the material of the valve ball. If it is normal, check whether the radiator outlet pipe is collapsed, whether the inner hole is delamination and blockage, find out the cause and eliminate it.　　 If it is not the problem of cooling water leakage, the failure should be analyzed and eliminated in two cases. If it is not for the above reasons, it may be that the cooling system has too much scale and the water channel is not smooth. The thermostat is damaged in the closed position of the main valve; 　　

8. Please replace it with a new product. The water pump is damaged, the fan blades are reversed or deformed, and the wind ring is damaged; 　　7. The radiator guard net or the radiator core air passage is blocked by debris, resulting in poor heat dissipation; 　　5. 1. DBY stainless steel The electric diaphragm pump is suitable for low pressure, that is, where the outlet pressure is ;3kgf/cm2. Check the spindle and 'O' ring for scratches, abrasions and flattening marks, and replace them if they are damaged.

Please check whether the diaphragm is broken. If the thermostat is normal, it means that the diaphragm pump is damaged, and the water pump should be checked and repaired carefully. If the air volume is insufficient, the angle of the fan blades should be adjusted, and the blade head should be bent or changed. 3. For the phenomenon of excessively high temperature that does not appear suddenly, increase the engine speed to observe whether the water filler is turning over, and at the same time, pay attention to whether it is a large amount or a small amount.
