In the process of using the water ring vacuum pump, there are many problems, some of which are easy to solve, some of which may hurt the user, so this problem -- the surface of the device has a barb. If the surface of the equipment is equipped with barbs and other defects, it will accumulate dust and aggravate the damage of the mechanical equipment, and even more serious, it will cause certain harm to the user. But don't worry, the manufacturer will polish the equipment before leaving the factory.
1. Flame polishing: the surface of water ring vacuum pump is softened, baked and impacted by fire to remove the twill and wrinkle on the mechanical surface, but this way will reduce the flatness of the unit surface;
2. Polishing with polishing powder: high speed friction is carried out on the surface of the unit to remove scratches on the surface of the unit, but there are many materials used in this method and the process speed is relatively slow;
3. Acid treatment and polishing: the surface of the unit is treated with acid. When this method is used for polishing, the lines on the surface of the unit may not be completely removed.
After polishing, the surface of the water ring vacuum pump will be smoother and easier for the user to operate. However, the user should pay more attention to their own safety problems, check whether there is a problem before using the equipment, and take safety precautions.
