Biogas fan manufacturer briefly explains the difference between fan water cooling and air cooling

handong Mingtian Machinery Group, a biogas fan manufacturer, talked with friends about the methods of cooling Roots blowers before and after use. Generally speaking, fans have two cooling methods: water cooling and air cooling. Air cooling can be used under technical requirements. If the temperature If it is higher, water cooling is required. In order to ensure the normal use of the main and auxiliary oil tanks, cooling treatment is also required to reduce the temperature of the lubricating oil. Generally, the temperature of lubricating oil should not exceed 65°C. Another thing to note in winter is that when the water-cooled Roots blower is not used for a long time in winter, the water in the cooling pipe should be drained to avoid freezing and cracking of the cooling pipe.

Then there is some knowledge about aerators. The oxygenation power efficiency of jet roots blower exceeds that of water wheel type, inflatable type, water spray type aerators and other forms of aerators. Its structure is simple and can form water flow and stir the water body. The jet aerator can slowly oxygenate the water body without damaging the fish body, and is suitable for oxygenating fish fry ponds. The water jet aerator has a good oxygenation function, which can quickly increase the dissolved oxygen content of surface water in a short time. It also has an artistic viewing effect and is suitable for use in gardens or fish ponds in tourist areas. The deeper the water, the better the effect of the inflatable aerator, so it is suitable for use in deep water bodies. The inhalation aerator sends air into the water through negative pressure suction, and forms a vortex with the water to push the water forward, so the mixing force is strong.

The editor of Shandong Zhangqiu Blower Mingtian Machinery Group said that when designing Roots blowers, the gaps between impellers will also affect heat dissipation, such as casing gaps, impeller gaps, wall panel gaps, etc. These are also designed during the design The key point is that some small manufacturers have short service life of their equipment because of inadequate design. The editor has mentioned many times before that when we inspect a manufacturer, we must inspect the manufacturer's processing facilities and workshops. Workshop equipment can reflect a manufacturer's processing strength and testing standards. The impeller clearance design meets certain standards and should also be inspected during use. During the annual overhaul, dust and dirt on the impeller must be dealt with to ensure that the impeller clearance is within the standard error and that the clearance must not be too small. Appear.
