量を増大させることは着しく困難となる。Conventionally, a plantar is inserted into a cylinder and the plantar is reciprocated in the axial direction to pump liquid.1 A method of controlling the discharge flow rate of the I-ring manufactured by Lansha is to use a motor to drive the pump. How to control the rotation speed, ■How to control the stroke length of the silansha,
(2) There is a method of using both of (2) and (2) above. Among these control methods, when controlling the discharge flow rate of the I-ring using the method of controlling the rotational speed of the motor, the number of pulsations per unit time fluctuates, and for example, in an automatic analyzer, etc., the minute reagent Yuri is used for reaction systems where the reaction time is short. I can also think of something that could be done. In such a case, it is desirable to adopt the control method (2), but in this case, the pump discharge flow rate is expressed as the cross-sectional area of the gransha x the stroke length of the gransha, and the cross-sectional area of the gransha is Therefore, in order to increase the discharge flow rate, it is necessary to increase the stroke length. However, in reality, the stroke length cannot be increased infinitely. Discharge flow rate range li! 8 is naturally determined), and if you want to obtain a flow rate higher than that discharge flow rate range, you will need to replace the pump with a pump with a larger silansha cross-sectional area. On the other hand, when using the Grand Shine FF to send a fixed amount of liquid, the accuracy of the discharge flow rate of the Granger 4 ring can be improved by using a small-diameter plunger and increasing the stroke length, but in this case, as described above, As described above, it becomes extremely difficult to increase the discharge flow rate beyond a predetermined limit.

An impinging cylinder hole 9 is formed in the door 1 so as to be inclined upward in the direction of the passage, communicating with the passage 2 for transporting liquid held between the two check valves 5.8. Inside this cylinder hole 9, one end side of a cylindrical first silane gloss 10 is placed.
It is inserted movably back and forth along the axial direction, and is inserted into the box 11 formed in the opening of the cylinder hole 9.
Liquid tightness is maintained. On the other end side of the first plunger lO, a plurality of tooth grooves are formed along the entire circumference along the circumferential direction of the first plunger lO.

In addition, on the other end side of the second plansha, a plurality of tooth teeth are formed along the entire circumference along the circumferential direction of the second plansha. A pinion 19 fitted to the rotating shaft of the smoke 18 is meshed with the motor 1.
The plunger 15 is caused to reciprocate by repeating forward and backward rotation of the rotating shaft for a predetermined period of time when the rotation shaft 8 is activated. They can each be driven separately by the /# pulse signals sent by the.

は小径であるので、送液量は微小なものである。First, the control unit 20 is configured to set the amount of liquid to be fed, toggle, and start switch (
(not shown), a f pulse signal is sent from the control unit 20 to the second arm pulse motor 18, thereby causing the second arm pulse motor 18 to operate. In this case, an excitation current is sent to the first/intermediate pulse motor 13, but no pulse signal is sent, so the first intermediate pulse motor 13 does not rotate and remains in a fixed state. Then, the rotational motion of the rotating shaft of the motor 18 is converted into a linear motion of the small-diameter second f-run shear 16 (by the pinion 19 and the round rack portion 17&C), and thereby the second glanzia 16 moves forward along its axial direction. The liquid in the cylinder hole 9 is pressurized, and the liquid is forced to the outside via the upper check valve 8.Next, the rotation of the shimotor 18 is reversed in response to a signal from the control section 20, which causes the The second grandeur 16 retreats and the liquid to be sent is sucked in from the lower check valve 5. As a result, the second gransha 16 returns to the initial state IIVC, and thereafter the same operation is repeated to continue feeding the liquid.
Since the diameter is small, the amount of liquid fed is minute.

であるので、送液量は大きい。Next, when the liquid in the large lid is to be fed using the above-mentioned In, the control section 20 sends a signal of 9 to the 17th dulse motor 13. In response to this signal, the first parallel motor 13 is operated, and the rotating shaft of the motor 130 repeats forward and reverse rotations at predetermined intervals.
The first round rack part 12 makes linear reciprocating motion (transformed, and the 17th runner 10 reciprocates along its axial direction to transfer liquid. In this case, the first round rack part 12 Since the plunger 10 has a larger diameter than the second plunger 15, the amount of liquid fed is large.

流は送られるがノタルス信号は送られておらず、従りて
第２プランシヤ１５は固定状態にある。In this case, although an excitation current is sent to the second (2) quantity pulse motor 18, a notarus signal is not sent, and therefore, the second planshaft 15 is in a fixed state.

This is to reciprocate in parallel.

5 tanks, or a large-diameter first planar 10 alone or a first planar 10 and a second planar 15 for sending a large amount of liquid.
When used in combination with Yr, it is possible to vary the amount of liquid fed in a very wide range, and in this case, select a plunger suitable for the amount of liquid fed and increase the stroke length to increase the accuracy of liquid feeding. It is. In addition, 1 run tsuya 1 each
0.15 can be driven separately and independently, so if the drive order, drive speed, etc. of each plantar 10.15 are set and set in advance in the control section, it is necessary to use a special discharge curve pipe.
It can also be used together with ll, and can be used for %mu. In addition, each silane gloss is driven by a 9-lux motor 13.18, so the control is simple and accurate, and the liquid delivery accuracy is extremely high. It is. M9, cylinder hole 9 of the above pump
Since it is formed as an upwardly inclined chamber toward the passageway 2, there is no fear that air bubbles will remain on the upper wall surface of the cylinder hole 9 and cause a decrease in liquid feeding accuracy.

、送液貴社正確なものである。This pump has a 1st f. lance lO and a 2nd f.
It has a runsha 15i, and by operating these independently or simultaneously, the range of liquid feeding amount can be increased. Also, with the valve seat? - In general, when the discharge side of a plant pump using a check valve is negative, more liquid is sucked into the discharge side than the amount of liquid sent, and the liquid is sent.
Although the amount will be unstable, this pump is rotated intermittently around its axis by 10 degrees and 180 degrees, so that either the suction hole or the discharge hole is always closed. Therefore, even if the discharge side is in a negative pressure state, the liquid will not be sucked into the discharge side in an amount greater than the amount of liquid fed, and the liquid feeding company will be accurate.

In the plunger pump f that is force-fed from the discharge part to the outside of the cylinder, the gruntsha is formed into a cylindrical shape, and a gulansha of a smaller diameter than this is liquid-tightly inserted into the cylindrical plunger. Since the planshas are configured to independently reciprocate along the axial direction, the range of liquid feeding amount is extremely wide. Since the liquid can be selectively fed, the liquid feeding accuracy is extremely high.
