Self-suction sewage pump working principle First, self-suction sewage pump Overview: Self-suction sewage pump is based on repeated research on the basis of similar technologies at home and abroad to develop a novel structure of the product. Self-priming sewage pump set self-priming and non-clogging sewage in one, the axial backflow outside the mix, and through the pump, impeller flow channel unique design, as the general self-priming pump does not need to install the end of the valve and Irrigation, but also suction row contains large particles of solid and long fiber impurities in liquid can be widely used in municipal sewage projects, river pond farming, light industry, papermaking, textile, food, chemicals, electricity, fiber, slurry and mixed suspension Compared with the domestic similar products, self-priming sewage pump has the advantages of simple structure, good self-priming performance, strong sewage discharge capacity, high efficiency and energy saving, convenient use and maintenance and other characteristics. It belongs to the domestic sewage pump series products First. The technical performance indicators Habitat leading domestic and reached the international advanced level, has a broad application market and development prospects. Second, self-priming sewage pump use: self-priming sewage pump compared with similar products in the country, with a simple structure, self-priming performance, sewage capacity, high efficiency and energy saving, easy to use and maintenance features in the sewage pump products Is a national initiative. The technical performance indicators Habitat leading domestic and reached the international advanced level, has a broad application market and development prospects. 1 ambient temperature ≤ 45 ℃, medium temperature ≤ 60 ℃. 2. Medium PH value cast iron pump is 6 ~ 9, stainless steel pump is 1 ~ 14.3. Through the maximum particle diameter of 60% of the pump diameter, fiber length of 5 times the caliber. 4. The total weight of impurities in the media does not exceed 15% of the total weight of the media, the media does not exceed the proportion of 1240 kg / cubic meter Third, self-priming sewage pump seal wear and tear replacement: 1, check the foundation before installation level? 2, check the parts in transit have been damaged? 3, the pump itself is not allowed as pipe support? 4, pumps and piping should be kept well sealed. Check the pump base, couplings, bearings and other connections fasteners have loose? If loose should be tight. ◆ hand rotating coupling whether there are cassette tape or other phenomena? ◆ Open the pump above the water valve, add less than two-thirds of the reservoir water volume, close the valve. After boot without recharging. ◆ Connect the power trial turn, from the motor side, clockwise turn. (Reverse is strictly prohibited) ◆ boot, observe whether the operation is normal? If there is an abnormal phenomenon, should find out the reasons to be excluded.
