<p>The present invention relates to a piston pump without pulsation. The piston pump includes: a power driving part that comprises a first motor, which generates rotation power, and a second motor, which rotates while having a phase difference of 180°with respect to the first motor; a first piston part which receives rotation power, generated by the first motor, and discharges a certain amount of fluid, supplied through a first fluid supply pipe, through a first fluid discharge pipe; a second piston part which receives rotation power, generated by the second motor, and discharges a certain amount of fluid, supplied through a second fluid supply pipe, through a second fluid discharge pipe; a fluid transfer pipe that has an end portion, connected to the first fluid discharge pipe and the second fluid discharge pipe, and transfers the fluid, discharged through the fist fluid discharge pipe and the second fluid discharge pipe; a first rotation sensor that is installed on a rotation axis of the first motor, senses a rotation angle of the rotation axis, and generates a first rotation signal; a second rotation sensor that is installed on a rotation axis of the second motor, senses a rotation angle of the rotation axis, and generates a second rotation signal; a communication part that receives the first signal and the second signal, which are generated by the first rotation sensor and the second rotation sensor, and sends the first signal and the second signal to a signal control part; and the signal control part that checks an error of phase difference by comparing the first signal and the second signal.</p> |
