摘要： A double/triple-thread single-shaft eccentric screw pump is provided. The rotor of the pump overhangs little in comparison with the flange type connecting structure. The whole length of the pump is short, and the pump casing of the pump is short and small in diameter, so that the pump is small in size and light in weight. One end of a flexible rod is tapered and has a tapped hole formed at its axis. One end of the rotor has a tapered bore formed at its axis, into which the tapered end of the flexible rod is fitted. The rotor has a through bore formed at its axis, through which a tension bolt extends from the other end of the rotor. The tension bolt has a front threaded end, which is screwed into and fastened to the tapped hole of the flexible rod.

摘要： A rotor drive mechanism and pump apparatus according to the present invention may cause an external screw type rotor of a uniaxial eccentric screw pump to rotate and carry out a revolution movement. The rotor drive mechanism further comprises a shaft sealing structure configured such that a gap between an outer peripheral portion of an end portion of the revolution shaft is located on the external screw type rotor side and an inner peripheral portion of the casing in the pump apparatus is sealed. The rotor drive mechanism provides for a reduced amount of heat and vibrations to be generated when the rotor is rotated at high speed and further allows for lowering of contact pressure between an outer surface of the rotor and an inner surface of a stator inner hole.

摘要： A liquid material supply system includes a plunger pump, a flow regulating valve, an air-operated valve, a spring type accumulator and a dispenser. The plunger pump is connected to the flow regulating valve by a primary supply line. The flow regulating valve is connected to the dispenser by a secondary supply line. The on-off valve is connected to the secondary supply line. The accumulator is connected to the secondary supply line between the on-off valve and the dispenser. A pressure sensor detects the pressure substantially at the inlet port of the dispenser. This pressure is the basic for controlling the operation of the air-operated valve through an electromagnetic valve. The second chamber of the accumulator can store part of the liquid material supplied through the secondary supply line. The second chamber varies in volume with the balance between the force of the accumulator spring and the pressure in the secondary supply line so as to relax the pressure fluctuation in this line.
