Accompanying drawing explanation
Accompanying drawing 1 is the structural drawing of highi degree of accuracy proportion adjustment pump of the present invention.
Embodiment
Below in conjunction with accompanying drawing to highi degree of accuracy proportion adjustment pump of the present invention, be described further:
Highi degree of accuracy proportion adjustment pump of the present invention, be made up of pump case 1, piston 2, inlet one-way valve 3, Outlet check valves 4 and flow control valve 9, the middle part chamber 12 of described pump case 1 is piston chamber's cylinder body 11, entrance pipe 6 has been installed by one side cavity of pump case 1 and inlet one-way valve 3, opposite side chamber have installed Outlet check valves 4 and export pipeline 7, chamber between line entry and inlet one-way valve 3 is entrance chamber 13, be middle part chamber between the chamber between inlet one-way valve 3 and Outlet check valves 4, the chamber between Outlet check valves 4 and tube outlet is outlet chamber.Middle part chamber 12 is communicated with entrance chamber 13 by the circulation loop 8 in pump case 1, circulation loop 8 has been installed the flow control valve 9 with taper regulating valve stem 10.
The tail end of described piston 2 is hinged with connecting rod 16, and the other end of this connecting rod 16 is hinged with crank 15, and crank 15 is fixed on the output shaft of motor 14.Motor 14 provides power by linkage mechanism for piston 2, and piston 2 can be moved reciprocatingly.
Described inlet one-way valve 3 and the forward of Outlet check valves 4 are the direction of entrance pipe 6 to export pipeline 7.Namely the circulating direction of mother liquor in chamber can only be the direction from entrance pipe 6 to export pipeline 7.
Described flow control valve 9 is installed on the sidewall of pump case 1, and the taper regulating valve stem 10 on flow control valve 9 is interspersed to be actively tied on circulation loop 8.Taper regulating valve stem 10 is cone structure, and its object one is to ensure that seal is good, the more important thing is the shearing that can reduce mother liquor, makes the molecule of mother liquor be unlikely to too much to be broken to Small molecular thus thinning, and viscosity declines, and ensure that the quality of mother liquor.
Flow control valve 9 can be that manual tune also can for regulating automatically, if manually, flow control valve 9 installs handwheel or rotatable handle etc., the flow control valve 9 screwing in or screw out taper regulating valve stem 10 by operation handwheel and rotatable handle reaches the object of flow control; If be automatically regulate, then need install flowmeter 5 on export pipeline 7, flowmeter 5 and flow control valve 9 are connected with control system circuit respectively makes flowmeter 5, control system, flow control valve 9 form closed control circuit.Read flow parameter feedback at any time by flowmeter 5 to carry out adjusting the object reaching and control mother liquid flow rate in real time to flow control valve 9.
Highi degree of accuracy proportion adjustment pump of the present invention is three plunger proportion adjustment pumps in fact, and the application is convenient in order to describe, and the structural representation that the accompanying drawing of use is single plunger pump, also describes with single plunger pump.
The specific works mode of highi degree of accuracy proportion adjustment pump of the present invention is as follows:
Entrance pipe 6 is communicated with outside mother liquor header, starting electrical machinery 14, motor 14 drives piston 2 to move back and forth by crank 15 and connecting rod 16, when piston 2 is to chamber outdoor sport, the pressure of middle part chamber 12 is less than entrance chamber 13 and outlet chamber, mother liquor flows into middle part chamber 12 because pressure then can pass through inlet one-way valve 3 from entrance chamber 13, when piston 2 is to chamber indoor sport, middle part chamber 12 pressure is greater than outside pressure, mother liquor then can flow to entrance chamber 13 and outlet chamber from middle part chamber 12 due to pressure, but it is contrary that the opening direction of inlet one-way valve 3 and now mother liquor stream move direction, so mother liquor can be stoped to flow back to entrance cavity room 13, and only have Outlet check valves 4 mother liquor can be allowed to pass through and flow to outlet chamber, flow out from export pipeline 7 immediately.Due to piston 2 to-and-fro motion under the effect of motor 14 and connecting rod 16, so mother liquor can circulate from entrance pipe 6 under the restriction of inlet one-way valve 3 and Outlet check valves 4 flow to export pipeline 7..
Because middle part chamber 12 has been communicated with circulation loop 8 with entrance chamber 13, circulation loop 8 is installed the flow control valve 9 with taper regulating valve stem 10, taper regulating valve stem 10 regulates the opening of circulation loop 8 by screwing out or screwing in, thus determines the refluence flow due to the mother liquor under the effect of pressure.Regulating valve stem 10 screws out, the enlarged open of circulation loop 8, then mother liquor refluence amount can increase, thus the mother liquid flow rate of export pipeline 7 can reduce relatively; In like manner regulating valve stem 10 screws in, the openings get smaller of circulation loop 8, and mother liquor refluence amount reduces, thus the mother liquid flow rate of export pipeline 7 increases relatively.Reach and control the accurately adjustable object of mother liquid flow rate.When regulating valve stem 10 screws in completely, the mother liquid flow rate of export pipeline 7 is maximum, and when taper regulating valve stem 10 screws out completely, the mother liquid flow rate of export pipeline 7 is minimum.
If flow control valve 9 is automatically regulate, flow control valve 9 is provided with electric actuator 17, utilizes the clockwise and anticlockwise of electric actuator 17 to reach the accurate control of flow.Specifically, that flowmeter 5, control system, flow control valve 9 are formed closed control circuit, flow control valve 9 is fed back to by control system after flowmeter 5 detects flow parameter, flow control valve 9 controls taper regulating valve stem 10 according to after the parameter comparison of setting again, again detected by flowmeter 5 after the changes in flow rate of mother liquor outlet one-way valve 4, thus again feed back to flow control valve 9, reach such closed loop control, the state regulated and controled at any time.
Highi degree of accuracy proportion adjustment pump of the present invention, can when not needing mother liquor discharge capacity accurate, flow control valve 9 is provided with regulating handle, adopt the mode of manual tune to adjust mother liquor discharge capacity, also can, under the effect of control system, make regulator, control system, flowmeter form closed control circuit, highi degree of accuracy adjustment is carried out to flow, in addition because regulating valve stem is taper, it reduces greatly to the shearing of mother liquor, makes the mother liquor Quality advance of output.
