Water ring vacuum pump Water ring vacuum pump uses water as the working fluid to extract vacuum. In the industrial production process, corrosive gases will inevitably be encountered. At this stage it is necessary to make the correct selection of material. the water ring vacuum pump. , water ring vacuum pumps produced and sold by Shanghai Feilu Vacuum Pump Factory include gray iron, ductile iron, stainless steel impellers, copper impellers, steel flow parts stainless steel and overall stainless steel materials. Gray cast iron, water ring vacuum pump material: Gray cast iron is cast iron obtained by fully carrying out the first stage graphitization process. All or most of the carbon exists as flake graphite, and the fracture surface is. gray, so named after him, it includes general gray cast iron (called gray cast iron),inoculated cast iron, rare earth gray cast iron, etc. In order for the pump to operate safely and have a long service life, attention must be paid to daily maintenance. Maintenance should pay attention to the following aspects: Maintenance of mechanical seal: - Water ring vacuum pumps should regularly detect the pressure and water volume of the seal. , and always keep a small amount of clean water flowing along the shaft, adjust the gland regularly, check the packing and replace it regularly. The shaft seal water pressure and shaft seal water volume must meet the above requirements (shaft seal inspection). When a pump equipped with a mechanical seal is not used for a long time, the mechanical seal part should be filled with N46 engine oil to prevent the mechanical seal parts from rusting and the internal parts rubber does not fallt broken down. Impeller adjustment: In order to ensure efficient operation of the pump, the gap between the impeller and the front guard plate should be adjusted in time. When adjusting the impeller gap, first stop the pump, loosen the bolts compressing the bearing assembly, then. adjust the nuts on the bolts so that the bearing assembly moves toward the pump. Move forward and at the same time turn the shaft by hand in the direction of rotation of the pump until the impeller rubs against the front guard plate. the nut just tightened at the front half a turn, then tighten the nut in front of the adjustment bolt to move the bearing assembly rearward. At this point, the gap between the wheel and the front skid plate is between 0.51mm. After adjustment, check again whether the wheel rotation is normal and whether the bearing mounting bolts are tight before starting again. --Water ring vacuum pump
600Pa. Water ring vacuum pump, water inlet pressure 600Pa. The waterproof vacuum pump is a vacuum pump used to pump underground biogas. This vacuum pump has high discharge negative pressure and low flow rate. It is suitable for use in mines with small discharge volume and high negative discharge pressure.
