Description
Technical field
The invention belongs to diaphragm pump, relate to the displacement control device of diaphragm pump, is specifically a kind of membrane pump fluid end of the adjust flux that can be in operation.
Background technique
Now widely used diaphragm pump is displacement pump, and the flow of its each punching is constant, in use, wants to change flow, must change the parts such as piston (or plunger), cylinder sleeve after termination of pumping.Not only wasting manpower and material resources but also waste time, especially magna pump, in the wild during operation by the restriction of lifting appliance, change and once need the long period.Some operation procedure can not termination of pumping, and termination of pumping may cause slip to precipitate, and recovers to get up to need at substantial manpower and materials, delays long time.The problem that the flow that diaphragm pump exists all the time can not regulate automatically is not well solved.Do studied in earnest to address this problem designer of the present invention, proposed goal of the invention of the present invention.
Summary of the invention
Goal of the invention of the present invention in order to overcome current diaphragm pump exist flow can not self-adjusting deficiency put forward.Namely a kind of membrane pump fluid end of the adjust flux that can be in operation is provided.
Technical solution of the present invention realizes like this, the membrane pump fluid end of this adjust flux that can be in operation, there is the chamber of septum (1) and hydraulic chamber (6) that are fixed with one, cylinder sleeve (9) after hydraulic chamber, hydraulic chamber and cylinder sleeve are fixed on the frame header board (8) of diaphragm pump, barrier film (2) is equipped with in chamber of septum, the guide rod (3) of diaphragms extends in hydraulic chamber, piston (10) is combined with in cylinder sleeve (9), hydraulic chamber have outlet valve (7) and oil charge valve (11), it is characterized in that on hydraulic chamber (6), be equipped with a Flow-rate adjustment room (4) controlled by valve (5).
Useful technique effect of the present invention is: by filling inert gas or the liquid of different pressure or volume to flow conditioning chamber inside, change the volume of diaphragm pump hydraulic chamber inside, realize limited control to diaphragm pump discharge capacity, thus overcome the problem that diaphragm pump discharge capacity all the time can not regulate automatically.And structure simple operations is easy to use, safe and reliable.
Accompanying drawing explanation
Accompanying drawing is structural profile schematic diagram of the present invention.Sequence number is in the accompanying drawings illustrated as: 1, chamber of septum, and 2, barrier film, 3, guide rod, 4, Flow-rate adjustment room, 5, flow control valve, 6, hydraulic chamber, 7, outlet valve, 8, frame header board, 9, cylinder sleeve, 10, piston, 11, oil charge valve.
Embodiment
Below in conjunction with the embodiment provided in accompanying drawing, structure of the present invention and use are described in detail.With reference to accompanying drawing, this kind can be in operation the membrane pump fluid end of adjust flux, there is the chamber of septum (1) and hydraulic chamber (6) that are fixed with one, cylinder sleeve (9) after hydraulic chamber, hydraulic chamber and cylinder sleeve are fixed on the frame header board (8) of diaphragm pump, barrier film (2) is equipped with in chamber of septum, the guide rod (3) of diaphragms extends in hydraulic chamber, piston (10) is combined with in cylinder sleeve (9), hydraulic chamber have outlet valve (7) and oil charge valve (11), it is characterized in that on hydraulic chamber (6), be equipped with a Flow-rate adjustment room (4) controlled by valve (5).
Have a capsule in Flow-rate adjustment room (4), Flow-rate adjustment room is divided into inflatable chamber and the oil-filled chamber be communicated with diaphragm pump hydraulic chamber by valve (5) by this capsule.
The quantity that flow reconciles room can set according to the need of work of diaphragm pump,
Valve (5) can adopt manually-operated gate, also can adopt the valve of hydraulic control or pneumatic control, and in order to improve the automatic control ability of diaphragm pump, valve (5) can be solenoid valve.This solenoid valve can pass through automatic control circuit, realizes the automatic, manual of diaphragm pump discharge capacity and telecontrol.
This fluid end working procedure is: according to the maximum pump discharge of operation procedure determination pump, cylinder sleeve, piston that assembling is corresponding.Be filled with inert gas (generally can be filled with nitrogen or carbon dioxide) in the capsule of Flow-rate adjustment room, minimum inflation pressure 0.5MPa, the highest inflation pressure is 80% of pump rated pressure, according to Flow-rate adjustment amount, determines inflation pressure value.The inflation pressure of same each capsule of pump should be identical.
Before pump operation, barrier film and piston are moved to rear end initial position (shown position), in hydraulic chamber, be full of hydraulic oil, and by outlet valve emptying air.Start pump, can normally work.
The flow of pump is reduced if want, when piston travels forward from rear end, open flow control valve, in hydraulic pressure cavity, under piston thrust effect, just some enters Flow-rate adjustment indoor to hydraulic oil, like this, the hydraulic oil promoting barrier film then decreases this part flow, thus the flow that pump diaphragm room is discharged reduces same traffic.
In the capsule of Flow-rate adjustment room, inflation pressure can be designed to according to setting pressure Non-follow control or automatically control, and the unlatching of flow control valve can be designed to manually, also can be designed to telecontrol.
Recover the former flow of pump if want, at the end of piston sucks, close modulating valve, now, the hydraulic oil of Flow-rate adjustment indoor is all discharged under the promotion of capsule expansive force, because flow control valve is closed, hydraulic oil no longer can enter flow and reconcile room, and pump returns to again original flow.
Claims (2)
1. the membrane pump fluid end of adjust flux that can be in operation, there is the chamber of septum (1) and hydraulic chamber (6) that are fixed with one, cylinder sleeve (9) after hydraulic chamber, hydraulic chamber and cylinder sleeve are fixed on the frame header board (8) of diaphragm pump, barrier film (2) is equipped with in chamber of septum, the guide rod (3) of diaphragms extends in hydraulic chamber, piston (10) is combined with in cylinder sleeve (9), hydraulic chamber have outlet valve (7) and oil charge valve (11), it is characterized in that on hydraulic chamber (6), be equipped with a Flow-rate adjustment room (4) controlled by valve (5), Flow-rate adjustment room (4) has a capsule, Flow-rate adjustment room is divided into inflatable chamber and the oil-filled chamber be communicated with diaphragm pump hydraulic chamber by valve (5) by this capsule.
2., according to the membrane pump fluid end of a kind of adjust flux that can be in operation according to claim 1, it is characterized in that said valve (5) is solenoid valve.
