Submersible sewage slurry pump of fixed and mobile
Submersible sewage slurry pump installation with fixed and movable two. When using a fixed automatic installation, should be the chain were put into (deviation from the slurry pump outlet, the connection should be parallel to the slurry pump outlet) two screw ring or lifting plate on lifting slurry pump. Slowly and evenly along the guide rail slide, in place until the automatic coupling. When using mobile installation, the tube well, with the chain cable passes through the two rings on the lifting slurry pump, pay attention to cut will not use cables as the rope, to avoid danger. Therefore, the anti blocking and reliability is an important factor in the merits of sewage slurry pumps. And other slurry pumps, impeller, the pressurized water chamber, are the two core parts of sewage slurry pump. Its performance, also on behalf of slurry pump performance, the anti clogging sewage slurry pump performance, efficiency, and cavitation performance, anti abrasion performance of the main lobe slurry pump and pressure by the two major components to ensure the water chamber.
1, the impeller structure: structure of the impeller is divided into four categories: blade type (open, closed), swirl, flow type, (including the single channel and dual channel) spiral centrifugal four open, semi open impeller manufacture is convenient, when the impeller blocked, can clean and repair easy, but in the long run, the particles will make the clearance of blade abrasion and water pressure chamber side wall to increase, thus reduces the efficiency of. And the gap will increase the pressure on the distribution of leaf damage. Vortex is not only the loss of, and the slurry pump will increase the axial force, at the same time, as a result of increased space, flow of liquid flow in the stability of damage, so that the slurry pump vibration, the impeller type is not easy to transport with large particles and long fibers of the media, from the performance perspective, the type of impeller efficiency low, maximum efficiency is about the equivalent of ordinary 92% of the closed impeller, a relatively flat head curve.
