The regulator unit is mounted on the top of the motor. Mainly include: planetary gear reducer, spiral adjustment mechanism, digital tube display components, etc.. To the output shaft of the speed reducer drives the adjusting rod, adjust the positive and reverse rotation of the rod, force bearing mechanism and motor pull rod up and down movement affects components impeller linkage and rotate the blade, achieve the purpose of adjusting the angle of the blade.
Because these two types of pumps is a large water pump equipment, its structural features decided it could not, in the factory the whole assembly, but only some wear and do some necessary tests and complete assembly and debugging work must be in the site installation site. So large water pumps are generally motor and impeller components shipped to the site assembly and adjustment device is installed and blade angle linkage adjustment tests, if any fault occurs, it is necessary to open the inspection is very difficult and every piece of leaf angle synchronization adverse to observe.
