Abstract
The utility model discloses an automatic oil discharge and supplement device of a membrane pump. The automatic oil discharge and supplement device is provided with a membrane room and a hydraulic cavity which are fixedly connected into a whole. A cylinder sleeve is arranged at back of the hydraulic cavity. The hydraulic cavity and the cylinder sleeve are fixed to a machine frame front plate of the membrane pump. A membrane is arranged in the membrane room. A guide rod above the membrane stretches into the hydraulic cavity. A piston is arranged in the cylinder sleeve in a matched mode. An exhaust valve and an oil charge valve are arranged on the hydraulic cavity. The automatic oil discharge and supplement device is characterized in that an oil discharge valve and an oil supplement valve are arranged on the hydraulic cavity, a valve rod of the oil discharge valve and a valve rod of the oil supplement valve are respectively connected with a connecting rod, and stroke positioning blocks are arranged on the membrane guide rod and are matched with the connecting rod connected with the valve rod of the oil discharge valve and the connecting rod connected with the valve rod of the oil supplement valve respectively. The automatic oil discharge and supplement device has the advantages that the stroke positioning blocks fixed above the guide rod are matched with the connecting rod connected with the valve rod of the oil discharge valve and the connecting rod connected with the valve rod of the oil supplement valve, so that automatic oil discharge or automatic oil supplement is achieved. The mass of oil in the hydraulic cavity of the membrane pump can be kept basically constant through automatic control, and normal work of the membrane pump can be guaranteed.
Description
Technical field
The utility model belongs to diaphragm pump, the automatic control component of diaphragm pump particularly, and definite saying is a kind of diaphragm pump automatic oil draining recharging oil device.
Background technique
For the diaphragm pump of current practicality, when the work, along with the to-and-fro motion of piston, the hydraulic oil in hydraulic chamber, under the effect of piston, drives barrier film to-and-fro motion, thereby completes suction, the discharge process of pump.Hydraulic pressure oil mass in hydraulic pressure cavity must keep constant, to guarantee that the barrier film pole location that seesaws fixes.Otherwise barrier film can break very soon.If low on fuel in hydraulic pressure cavity, in charging ending phase, barrier film can break because clashing into diaphragm cavity rear wall; Oil mass is too much, and in discharge ending phase, barrier film can break because of overexpansion.Therefore, the oil mass that must control in hydraulic chamber is constant, to guarantee diaphragm pump normal operation.In order to achieve this end, designer of the present utility model has done research in earnest, has proposed goal of the invention of the present utility model.
Model utility content
Goal of the invention of the present utility model puts forward in order to overcome the deficiency that in the diaphragm pump hydraulic chamber of above-mentioned existence, oil mass substantially constant is not easy automatically to control.A kind of diaphragm pump automatic oil draining recharging oil device is provided.
Technical solution of the present utility model is to realize like this, this diaphragm pump automatic oil draining recharging oil device, there is the chamber of septum (1) and the hydraulic chamber (7) that are fixed with one, after hydraulic chamber, be cylinder sleeve (10), hydraulic chamber and cylinder sleeve are fixed on the frame header board (9) of diaphragm pump, in chamber of septum, be equipped with barrier film (2), the guide rod of diaphragms (3) extends in hydraulic chamber, in cylinder sleeve (10), be combined with piston (11), on hydraulic chamber, there is outlet valve (8) and oil charge valve (12), it is characterized in that being equipped with a draining valve (4) and a Fill valve (5) on hydraulic chamber (7), the valve rod of draining valve and Fill valve is being connected connecting rod (13), on barrier film guide rod (3), there is the connecting rod cooperation that a stroke positioning block (6) is being connected with Fill valve valve rod with draining valve respectively.
Useful technique effect of the present utility model is: by being fixed on the cooperation between the connecting rod connecting on the valve rod of stroke positioning block above guide rod and draining valve and Fill valve, realize automatic oil draining or repairing automatically.Reach automatic control for the oil mass substantially constant in the hydraulic chamber of diaphragm pump, guarantee the object of diaphragm pump normal operation.
Accompanying drawing explanation
Fig. 1 is structural profile schematic diagram of the present utility model.Sequence number is in the accompanying drawings illustrated as: 1, chamber of septum, 2, barrier film, 3, guide rod, 4, draining valve, 5, Fill valve, 6, stroke positioning block, 7, hydraulic chamber, 8, outlet valve, 9, frame header board, 10, cylinder sleeve, 11, piston, 12, oil charge valve, 13, connecting rod.
Embodiment
Below in conjunction with the embodiment who provides in accompanying drawing, structure of the present utility model and use are elaborated.With reference to accompanying drawing, this kind of diaphragm pump automatic oil draining recharging oil device, there is the chamber of septum (1) and the hydraulic chamber (7) that are fixed with one, after hydraulic chamber, be cylinder sleeve (10), hydraulic chamber and cylinder sleeve are fixed on the frame header board (9) of diaphragm pump, in chamber of septum, be equipped with barrier film (2), the guide rod of diaphragms (3) extends in hydraulic chamber, in cylinder sleeve (10), be combined with piston (11), on hydraulic chamber, there is outlet valve (8) and oil charge valve (12), it is characterized in that being equipped with a draining valve (4) and a Fill valve (5) on hydraulic chamber (7), the valve rod of draining valve and Fill valve is being connected connecting rod (13), on barrier film guide rod (3), there is the connecting rod cooperation that a stroke positioning block (6) is being connected with Fill valve valve rod with draining valve respectively.
This device is after adopting, and the working procedure of diaphragm pump is such: before pump operation, barrier film and piston are moved to rear end limit position (right end position in diagram), by oil charge valve, in hydraulic pressure cavity, be full of hydraulic oil, and by outlet valve emptying air, start pump, can work.In hydraulic pressure cavity, during low on fuel, pump barrier film when suction process finishes can surpass the break point of setting, corresponding, stroke positioning block on guide rod moves to the right side in accompanying drawing, just promotes Fill valve connecting rod, and Fill valve is opened, hydraulic oil is just filled with hydraulic pressure cavity, and oil is supplemented.It is normal that diaphragm stroke is recovered.When in hydraulic chamber, oil mass is too much, when piston moves to front end, barrier film can surpass the break point of setting, stroke positioning block on corresponding guide rod moves to the left end in accompanying drawing, as two-dot chain line position in accompanying drawing, just promote draining valve connecting rod, draining valve is opened, unnecessary hydraulic oil is discharged, and it is normal that diaphragm stroke is recovered.As long as adjust the position of the stroke positioning block on guide rod, just can rationally control the volume that holds hydraulic oil in hydraulic chamber, can meet the action request of suction and the discharge of diaphragm pump, reach the reliable operation of diaphragm pump, extend the working life of diaphragm pump and operation, the maintenance cost of minimizing diaphragm pump.There is service-strong distinguishing feature simple in structure.
