Sewage lift pump plays an important role in optimizing the home environment, the sewage lifting device used at home, of course, hope to use the time to be as long as possible. Now to introduce how to maintain the sewage pump. Sewage lifting pump Lifting pump is a sewage processor, used in daily life or factory more and the frequency is very high, to enhance the type of pump we generally divided into two kinds of mobile QW and fixed WQ, if according to the material Category We can be divided into stainless steel, cast iron two. How to extend the service life of sewage pump, the correct maintenance is the key. 1, the use of sewage lifting equipment must be exhausted equipment and piping in the remaining water to prevent corrosion caused by sewage. 2, if conditions permit, we can remove the equipment and piping in the cleaning sewage pump to clean up. 3, to always check the ball bearings equipment, such as the jacket wear, Kuangmian, ball wear or surface spots have to be promptly replaced. 4, regularly check the equipment on the impeller for cracks or holes, check the impeller nut is loose signs, if there is a problem to replace or adjust. 5, sewage pump to promote the pump when not in use, the tape should be removed, washed with warm water to dry after preservation. Do not have a direct place to save the place, nor the presence of oil, corrosive substances. Also note that no matter under what circumstances, the tape should not be stained with oil, diesel or gasoline and other oil substances, do not apply rosin and other adhesive tape to prevent tape corrosion. 6, all the screws on the device, bolts should be scrubbed with a wire brush, and then coated with oil or immersed in diesel oil preservation.

Self Drilling Screw
Self drilling Screw made of 410 stainless steel, high hardness (40 Rockwell C), steel process.
Drilling screw is also very strong hardness, compared to the ordinary screw up, not only to maintain the ability is good, the connection object effect is also very strong, for the performance of the screw, are generally does not need auxiliary processing, can be directly on the object directly drill a Kong Sue into objects, not just use rise very convenient, Also can greatly improve the efficiency of work. This kind of drilling screw can be said to be the first choice of workers in various fields.
So what is the use of drilling screws?
1 stainless steel plate, metal plate, galvanized steel plate, engineering installation.
2 metal curtain wall metal light compartment and other indoor and outdoor installation.
General Angle steel, channel steel, iron plate and other metal materials combined installation.
4, automobile, container, shipbuilding, refrigeration equipment and other assembly projects.
