Device composition

The active piston type liquid flow standard device is mainly composed of a frame, a piston rod, a piston cylinder, a motor, a ball screw, a supporting optical axis, a sensor, and a protective shell. The piston rod is in close contact with the piston cylinder through the Y-shaped sealing ring, and the three together form a sealing chamber. The movement of the piston rod is realized by a servo motor, a coupling, a ball screw, and a supporting optical shaft. The piston rod and the ball screw lever are connected by a screw nut, and the movement direction is determined by a servo motor and a ball screw.

A suction pneumatic valve and a discharge pneumatic valve are installed at the outlet of the piston cylinder. The suction pneumatic valve is connected with the water tank, and the drainage pneumatic valve is connected with the instrument pipeline. Install high-precision temperature and pressure sensors.
