A lot of products are used, the installation work is very important, especially the more sophisticated equipment or people are less exposed to the device. For example, household self-priming pump, as the name suggests, it is more suitable for household use, how to operate the home self-priming pump installation? Should there be any areas that need attention? These issues deserve attention. Home self-priming pump installation diagram 1, the pump and the motor direct drive, should pay attention to the coaxiality of the pump shaft and the motor output; pump installation accuracy or not have a greater impact on the smooth operation of the pump and service life, Therefore, careful calibration must be installed. 2, the pump coupling must be solid and good nut, and lock the nut, beware of nut loose, otherwise easy to cause the impeller to move, resulting in mechanical failure. 3, in order to pump the body to maintain a certain amount of storage solution, in order to achieve better self-priming capacity and prevent mechanical seal dry friction, the pump must be imported higher than the pump shaft centerline. 4, the pump is installed, should make the electrostatic resistance of the pump and pipe grounding resistance meet its requirements. 5, the installation should be strictly checked pump casing and piping in the presence of stones, iron sand and other debris. 6, correction of pump coupling and motor coupling installation clearance and coaxiality, its different axis tolerance to 0.1mm. The difference between the pump shaft and motor shaft height can be adjusted on the foot pad copper or iron. 7, 3-4 hours after the actual operation of the unit for the final inspection, if no adverse phenomena, the main installation has been properly, the shaft should be checked in the test run. 8, the pump bearing body cooling unit equipped with a cooling water connector for the hole with 12 holes for the hose or plastic pipe, the thread size M12x1.75. 9, in the pump outlet pipe if equipped with a one-way valve in the process of self-priming can not make the pump discharge gas smoothly, should be connected to the outlet of the pump exhaust pipe and valve. Through the above analysis, we can understand that domestic self-priming pump installation requires attention and care matters more. It is precisely because of the emergence of these situations, so that users will care more in the use of the product, the product will certainly be better after the auxiliary role. People always say that sharpening does not mistakenly cut the woodworking, only the relevant work is fully prepared, we use the product to maximize the value of the product.
