Hollow Rotor Downhole Motor
Product Description
To increase the hydraulic horsepower and the upward speed of mud stream, rotor is manufactured into hollow rotor with nozzles. Thus, more total flow rate is equal to the sum of the flow rate through seal cavity and rotor. Each type of motor has its own recommended maximum and minimum flow rate. If flow rate is too high, rotor maybe run at over speed and earlier damage would occur to stator and rotor. If it is too low, motor will stop operating. Therefore, the flow rate through seal cavity shall be ensured or even higher than the recommended value while selecting nozzle size. Only in this way, can motor keeps on normal operation.
