The motor shaft by an assignment, cylinder 2, piston 3, beam 4, roller 5, the stator 6 and the output shaft 7 and so on. This motor displacement than single stroke motors increased 1 times. Equivalent of 21 plungers. Since the increase in the number of equivalents of the plunger, under the same operating pressure, a corresponding increase in the output torque, the torque ripple rate decreases. Sometimes this motor is made of multi-slice homemade plunger pump repair phone number plunger more output torque further increase domestic pump maintenance, the torque ripple rate is further reduced. Such displacement of the motor can be made so large, and may be smooth operation at low speed into the next. Due to the rotation of the motor need two-way domestic pumps sale, so the blade slots radially arranged hydraulic pump at rated pressure and rated flow, its motor power can be detected directly from the sample pump. In general, according to the formula to calculate the power required for the motor. When on the steam map Nt gentle curve, according to the work cycle, the maximum power point selection formula: N = (Ps * Qp) / η N-- prime mover power Ps * Qp-- product pump pressure and flow η-- maximum pump efficiency. Gear pumps 0.6-0.7; vane pump 0.6-0.75; 0.8-0.85 piston pump repair Domestic | Crystal Chong Hydraulic (certified) | pump from Jinan Jing Chong hydraulic machinery Limited.
