Water pumps on the water supply equipment need regular cleaning, especially the application of water supply equipment, cleaning is not timely, not completely will cause pollution to the water, the service life of the pump also have a significant impact. How to clean the pump without negative pressure water supply equipment? 1. To ensure that meet the requirements of the degree of cleanliness of the parts, in the repair, a variety of different parts, the degree of cleaning requirements are not the same. In the assembly, the cleaning requirements of the mating parts are higher than the non-mating parts, the moving parts are higher than the static parts, and the precision parts are higher than the non-precision parts. For spray, plating, bonding the surface of the workpiece, the cleaning requirements are high. Cleaning must be based on different requirements, take a different cleaning agents and cleaning methods to ensure the required cleaning quality. 2. To prevent corrosion of parts, precision parts do not allow any degree of corrosion. When parts to be parked for some time after cleaning, should consider the antirust ability of the cleaning fluid or consider other anti-rust measures. 3. To ensure safe operation, to prevent fire or poison the human body and cause environmental pollution. 4 emphasis on economic benefits, in ensuring the above conditions, should be to improve work efficiency, reduce raw material costs, reduce equipment costs to improve economic efficiency as a precondition.

Steel Bend
Steel bends and steel elbows are both very common pipe fittings which are used to change the flowing direction in a piping systems. In addition to pipe fittings for connecting , elbow pipe also refers to a processing method. It is to Bend the straight pipe through the processing method to achieve the purpose of changing the circulation direction of the pipeline. The manufacturing process and the finished product are called pipe bend.
In order to ensure that the wall thickness of the bending part is no less than that of the straight pipe part, the minimum radius of the pipe bending should be 3D( the D means nominal diameter of this bend). The specific size depends on the operating conditions. That is to say, radius is not restricted as long as it exceeds 3D, which can be 3D or 3.2D, even 4D, 5D, 6D and 8D are also acceptable. In addition, the angle of the bend can be in any degree, some times there are also custom-designed bends which are 22.5 °, 45 °, 90 °, 135 °, 180 °, 270 ° and so on.
