≪About single-shaft eccentric screw pump≫
Subsequently, the uniaxial eccentric screw pump 110 (hereinafter, also simply referred to as “pump 110”) will be described. FIG. 4 is a cross-sectional view of the pump 110. The pump 110 is a so-called rotary displacement pump, and has a configuration in which a stator 120, a rotor 130, a power transmission mechanism 150, and the like are accommodated in a casing 112. The casing 112 is a cylindrical member made of metal, and a needle 114a is provided on a nozzle 112a attached to one end in the longitudinal direction. In addition, an opening 114 b is provided in the outer peripheral portion of the casing 112. 114 b communicates with the internal space of the casing 112 at an intermediate portion 112 d located at an intermediate portion in the longitudinal direction of the casing 112.

  The needle 114a and the opening 114b are portions that function as a discharge port and a suction port of the pump 110, respectively. More specifically, the pump 110 rotates the rotor 130 in the forward direction so that the needle 114a functions as a discharge port and the opening 114b functions as a suction port. It is possible to pump a resin as a raw material of the product. The opening 114b is connected to a lead-out pipe (not shown) through which resin in a storage container (not shown) is supplied.

  The stator 120 is a member having a substantially cylindrical appearance. The material of the stator 120 is appropriately selected according to the type and property of the fluid (here, resin) that is the object to be transported using the pump 110. The stator 120 is accommodated in the stator attachment portion 112b in the casing 112 at a position adjacent to the needle 114a. The outer diameter of the stator 120 is substantially the same as the inner diameter of the stator attachment portion 112b. Therefore, the stator 120 is mounted in a state where the outer peripheral surface thereof is in close contact with the inner peripheral surface of the stator mounting portion 112b. Further, one end of the stator 120 is sandwiched by the nozzle 112 a at the end of the casing 112.

  As shown in FIG. 5, the inner peripheral surface 124 of the stator 120 has a multistage female screw shape with two threads. More specifically, inside the stator 120, through-holes 122 extending along the longitudinal direction of the stator 120 and twisted at the above-described pitch are provided. The stator 120 is d times (d) the reference length S when the reference length S is a lead length L (a length obtained by multiplying the pitch length by the number of ridges) of the internal thread-shaped portion formed inside. (= Natural number) is a multistage (d stage) female thread shape. Further, the through-hole 122 is formed so that its cross-sectional shape (opening shape) is substantially oval when viewed in cross-section at any position in the longitudinal direction of the stator 120.

  The internal diameter Di of the female thread-shaped portion formed by the inner peripheral surface 124 of the stator 120 is a length from the opening 114b side (right side in FIG. 5) serving as a suction port toward the needle 114a side (left side in FIG. 5) serving as a discharge port. It is formed in a step shape so that the diameter is increased every time it advances in the longitudinal direction by L.

  The rotor 130 is a metal shaft, and has a single-stage multi-stage eccentric male screw shape. More specifically, the lead length L of the rotor 130 is the same as that of the stator 120 described above. The rotor 130 is formed to have a multi-stage (d stage) male screw shape having a length d times (d = natural number) the reference length S corresponding to the length L of the lead. The rotor 130 is formed so that its cross-sectional shape is substantially a true circle when viewed in cross section at any position in the longitudinal direction. The rotor 130 is inserted into the through hole 122 formed in the stator 120 described above, and can be freely rotated eccentrically inside the through hole 122. The outer diameter Do of the part formed in the male screw shape of the rotor 130 is a length L from the opening 114b side (right side in the figure) serving as a suction port toward the needle 114a side (left side in the figure) provided on the discharge side. It is formed in a step shape so as to reduce the diameter each time it advances in the longitudinal direction.

  When the rotor 130 is inserted into the stator 120, the outer peripheral surface 132 of the rotor 130 and the inner peripheral surface 124 of the stator 120 are in close contact with each other at their tangent lines, and the inner peripheral surface 124 of the stator 120 and the rotor 130 are in contact with each other. A fluid conveyance path 140 is formed between the outer peripheral surface and the outer peripheral surface. The fluid conveyance path 140 has a length d times the reference length S of the lead in the axial direction of the stator 120 and the rotor 130 when the length L of the lead of the stator 120 and the rotor 130 is the reference length S. It is a multistage (d stage) flow path. The fluid conveyance path 140 extends in a spiral shape in the longitudinal direction of the stator 120 and the rotor 130.

  Further, when the rotor 130 is rotated in the through hole 122 of the stator 120, the fluid conveyance path 140 advances in the longitudinal direction of the stator 120 while rotating in the stator 120. Therefore, when the rotor 130 is rotated, the fluid is sucked into the fluid conveyance path 140 from one end side of the stator 120 and is transferred toward the other end side of the stator 120 while being confined in the fluid conveyance path 140. It is possible to discharge at the other end side of the stator 120. The pump 110 according to the present embodiment is capable of pumping the fluid sucked from the opening 114b and discharging it from the needle 114a by rotating the rotor 130 in the forward direction.

  The power transmission mechanism 150 is provided to transmit power from the power source (not shown) such as a motor provided outside the casing 112 to the rotor 130 described above. The power transmission mechanism 150 includes a power transmission unit 152 and an eccentric rotation unit 154. The power transmission portion 152 is on one end side in the longitudinal direction of the casing 112, more specifically on the opposite side to the nozzle 112a and the stator mounting portion 112b described above (hereinafter also simply referred to as “base end side”). It is provided in the provided shaft accommodating portion 112c. Moreover, the eccentric rotation part 154 is provided in the intermediate part 112d formed between the shaft accommodating part 112c and the stator attachment part 112b.

  The power transmission unit 152 has a drive shaft, and is connected to a drive unit 165 including a servo motor and a speed reducer via the drive shaft. By operating the driving machine 165, the drive shaft can be rotated. Between the shaft accommodating portion 112c provided with the power transmission portion 152 and the intermediate portion 112d, a shaft seal device 161 including a burr seal 163, other mechanical seals, a gland packing, and the like is provided, whereby the intermediate portion 112d side Thus, the fluid that is the object to be conveyed does not leak to the drive unit 165 side.

  The eccentric rotating part 154 is a part that connects the drive shaft and the rotor 130 so that power can be transmitted. The eccentric rotating part 154 includes a connecting shaft 162 and two connecting bodies 164 and 166. The connecting shaft 162 is configured by a conventionally known coupling rod, screw rod, or the like. The connecting body 164 connects the connecting shaft 162 and the rotor 130, and the connecting body 166 connects the connecting shaft 162 and the drive shaft 156. Each of the coupling bodies 164 and 166 is configured by a conventionally known universal joint or the like, and can transmit the rotational power transmitted through the drive shaft to the rotor 130 to rotate the rotor 130 eccentrically. .
