Description of drawings
The measuring fixed amount pump structure schematic representation that Fig. 1 provides for the invention preferred embodiments.
Main symbol description: motor 1, cylinder 2, rotating shaft 3, two connecting rods 4, two pistons 5, water intake 6, water outlet 7, the first valve 8, the second valve 9, output shaft 10, chamber 11, controller 12, magnetic inductive block 14, sensor 15.
Embodiment
For the purpose, technological scheme and the advantage that make invention is clearer, below in conjunction with drawings and Examples, invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to the explanation invention, and be not used in the restriction invention.
See also Fig. 1, the measuring fixed amount pump structure schematic representation that it provides for the invention preferred embodiments.The measuring fixed amount pump comprises motor 1, cylinder 2, rotating shaft 3, two connecting rods 4, two pistons 5.
The two ends of cylinder 2 are respectively arranged with one group of water intake that is oppositely arranged 6 and water outlet 7, every group water intake 6 and water outlet 7 lay respectively at the relative both sides of this cylinder 2, each water intake 6 place is provided with the first valve 8, the pivot of this first valve 8 is positioned at this water intake 6 near on the side at these cylinder 2 middle parts, each water outlet 7 place is provided with the second valve 9, and the pivot of this second valve 9 is positioned on the side of this water outlet 7 away from these cylinder 2 middle parts.
Rotating shaft 3 is housed in this cylinder 2, and an end of this rotating shaft 3 and 10 coaxial connections of the output shaft of this motor 1, the other end of this rotating shaft 3 extend to that this cylinder 2 is interior to be divided into two chambers 11 with this cylinder 2, have one group of water intake 6 and water outlet 7 in each chamber 11.
Two connecting rods 4 are housed in respectively in these two chambers 11, and an end of each connecting rod 4 and the lug boss of this rotating shaft 3 are flexibly connected.Two pistons 5 are housed in respectively in these two chambers 11, and the piston 5 in the other end of each connecting rod 4 and the corresponding chambers 11 is fixing.
This measuring fixed amount pump is equipped with magnetic inductive block 14, sensor 15 and controller 12, and this sensor 15 cutting magnetic line when this magnetic inductive block 14 motion produces pulse signal, and this controller 12 is controlled the operation of this motor 1 according to this pulse signal.Particularly, side towards these cylinder 2 sidewalls on piston 5 embeds magnetic inductive block 14, sensor installation 15 on the outside of these cylinder 2 sidewalls, this magnetic inductive block 14 and this sensor 15 are positioned on the relative both sides of same sidewall of this cylinder 2, this sensor 15 is electrically connected with controller 12, and this controller 12 is electrically connected at motor 1.This sensor 15 can be installed on the outer surface of this cylinder 2, and this controller 12 can be installed on the outer surface of this cylinder 2.
