Accurate Data Flow Control reciprocating pump of the present utility model, be made up of the pump housing, displacement transducer, acceleration sensor, flowmeter and processor, horizontal piston cavity and longitudinal liquid container is provided with in the pump housing, piston cavity to be communicated in the middle part of liquid container and to be provided with reciprocating piston in piston cavity, piston is provided with displacement transducer and acceleration sensor; Liquid container one end is communicated with entrance pipe and connectivity part is provided with one-way valve I, and the other end of liquid container is communicated with export pipeline and connectivity part is provided with one-way valve II; Flowmeter is located on export pipeline; One-way valve I, one-way valve II and flowmeter all connect with processor circuit.
As further improvement of the utility model, the length value of piston cavity is greater than the height value of liquid container.
As further improvement of the utility model, piston cavity and liquid container inwall are provided with and scribble ceramic coating.
As further improvement of the utility model, the connectivity part of piston cavity and liquid container is fixed with circular piston limit ring, and the front end of piston is the boss-shaped matched with piston limit ring.
Accurate Data Flow Control reciprocating pump of the present utility model, reasonable in design, avoid numerous and diverse manual control and calculating, utilize the closed loop control of the sensor such as flowmeter and displacement transducer, the fluid flow pumped into can be detected at any time and also regulate in real time according to actual needs.
Accompanying drawing explanation
Fig. 1 is the structural drawing of Accurate Data Flow Control reciprocating pump of the present utility model.
Embodiment
Below in conjunction with accompanying drawing to of the present utility model without Accurate Data Flow Control reciprocating pump, be described further:
Accurate Data Flow Control reciprocating pump of the present utility model is made up of the pump housing 1, displacement transducer 2, acceleration sensor 3, flowmeter 4 and processor.
Be provided with horizontal piston cavity 6 and longitudinal liquid container 7 in the pump housing 1, piston cavity 6 is communicated in the middle part of liquid container 7.
Reciprocating piston 8 is provided with in piston cavity 6, piston cavity 6 is fixed with circular piston limit ring 5 with the connectivity part of liquid container 7, the front end of piston 8 is the boss-shaped matched with piston limit ring 5, piston 8 is also provided with displacement transducer 2 and acceleration sensor 3, when setting piston 8 is positioned at piston limit ring 5, displacement transducer 2 initial value is zero.
Liquid container 7 one end is communicated with entrance pipe 11 and connectivity part is provided with one-way valve I 9, and the other end of liquid container 7 is communicated with export pipeline 12 and connectivity part is provided with one-way valve II 10, and the chamber formed between two one-way valves is communicated with piston cavity 6.
Flowmeter 4 is located on export pipeline and one-way valve I 9, one-way valve II 10 and flowmeter 4 all connect with processor circuit, and flowmeter 4, one-way valve I 9, one-way valve II 10 and processor form a closed control circuit.
For the ease of calculating and being conducive to accurate control, the length value of piston cavity 6 is greater than the height value of liquid container, and piston 8 front end is s from the maximum distance of the one-period of piston limit ring 5, and the stroke of piston 8 is S, then 0≤s≤S, the liquid volume in piston cavity 6 is then s π R
2, and in running between two one-way valves the liquid volume of chamber can regard immovable as, Accurate Data Flow Control reciprocating pump discharge liquid be exactly s π R
2.
In order to prevent noting the situations such as poly-corrosion, piston cavity 6 and liquid container 7 inwall are provided with and scribble ceramic coating.
Accurate Data Flow Control reciprocating pump of the present utility model, its concrete usage mode is as follows:
As shown in Figure 1, the below of one-way valve I 9 and one-way valve II 10 is entrance, top is outlet, the flow direction of liquid flows to export pipeline 12 from entrance pipe 11, in the flow process of liquid, certain amount of liquid is all pumped in each to-and-fro motion of piston 8, the size of this amount of liquid then depends on piston 8 at every turn away from the distance of piston limit ring 5, when piston 8 leaves gradually from the position of piston limit ring 5, displacement increases gradually by 0, displacement transducer 2 is started working, data are also sent to processor by the displacement amount of its real-time recording and analyses 8, piston 8 completes a to-and-fro motion, displacement becomes 0 again, twice displacement got by processor is crest value between 0, be the maximum distance s away from piston limit ring 5 in this cycle of motion of piston 8, liquid between the cavity entered between one-way valve I 9 and one-way valve II 10 and piston cavity 6 pumps by piston 8 in the process, its pump output is s π R
2, and the amount of liquid pumped in the unit time also depends on the movement velocity of piston 8.
Through export pipeline 12 when liquid pumps, the amount of liquid that flowmeter 4 Real-Time Monitoring at export pipeline 12 place pumps also feeds back in processor, and the movement velocity that processor adjusts piston 8 in time according to the flow of setting also displacement amount reaches requirement.
