Abstract
The utility model relates to a pump is with diaphragm maximum deflection self-control mechanism, it is by diaphragm (2), control lever (4), pure machinery such as plunger (5) is constituteed, no electric appliance component, ability automatically regulated diaphragm pump liquid chamber oil mass, guarantee pump stable performance, diaphragm deflection maximum value has been ensured in the design range, the diaphragm that has prevented that the diaphragm deflection from surpassing the design range and leading to breaks, service life has been guaranteed, the diaphragm limiting plate around having subtracted general diaphragm pump is necessary, this not only saves labour for material, and make the pump more be adapted to and carry media such as suspension, mud ore pulp.
Description
The utility model belongs to a kind of novel mechanical formula control mechanism that hydraulic diaphragm pump is used, and in more detail, is that a kind of hydraulic diaphragm pump is controlled barrier film maximum deflection mechanism automatically with mechanical type.
At present, the barrier film maximum deflection control mechanism of being seen domestic and international use has three kinds.First kind, adopt electromagnetic mode to control the maximum deflection mechanism of barrier film.External famous diaphragm pump manufactory---Dutch GEHO pump company adopts this technology to make diaphragm pump.As shown in Figure 2, it is made up of Electromagnetic Control bar (10), Electromagnetic Control probe (2a/2b), fluid infusion liquid discharging valve (3a/3b), oil pocket (11), oil pocket voltage stabilizer (11a), pressure governor (12), pressure governor barrier film (13), piston (14), pressure switch (15), cylinder sleeve (16), piston rod (17), barrier film (18), voltage stabilizer (21) and mud chamber (22) etc.This mechanism transforms by the non-electricity of controlling rod magnet and nonmagnetic body combination place, improve the power supply magnetic signal, commander's fluid infusion, liquid discharging valve 3a/3b work are discharged unnecessary oil with the oil of undercompensation, because of electromechanical, complex structure, and because of action only takes place between millisecond and microsecond, easily break down, reliability is relatively poor, in case element is out of order, with regard to cisco unity malfunction.Second kind is to adopt the compensating control valve formula, the diaphragm pump of dead point maximum deflection behind the control barrier film.External famous metering manufacturing company---German LEWA pump company and Japanese NIKKISO(day machine dress) company, just adopt this technology to produce diaphragm metering pump, its fluid end structure is made up of barrier film (23), warning device (26), safety exhaust (27), compensating control valve (28), plunger (29) and recuperation valve component such as (30) as shown in Figure 3.This technology is extensive use of on metering pump small-sized.It can control dead point deflection behind the barrier film, and the deflection of preceding dead point is forward limiting board, though the repairing of normally draining the oil, but the head pressure that when draining the oil, is higher than pump because of the diaphragm cavity internal pressure, easily cause the barrier film localized stress excessive and damage, or produce permanent deformation, also incompatiblely carry non-clean liquid.The third is that the structure with barrier film front and back, front and back confinement plate is seen Fig. 4.Be by plunger (31), filler (32), front and back limiting board (33) compensates a safety installations (34), expulsion valve (35), barrier film (36), suction valve parts such as (37) constitute, by deflection deformation before and after the limiting board control.Very few when oil mass, barrier film forms the vacuum repairing near the back confinement plate, and when oil mass was too much, barrier film was near preceding confinement plate, and pressure rises, and safety valve is opened oil extraction.This is the traditional metering diaphragm pump mechanism of typical case, is only applicable to the diaphragm pump of the pure medium of small-sized conveying.
The purpose of this utility model is the automatic control barrier film maximum deflection mechanism that proposes a kind of novel mechanical formula, be used for diaphragm pump, the deflection bending that makes barrier film by simple compensation hydraulic mechanism controls within the scope of design, gram is guaranteed the proper functioning of barrier film, prolong the life-span of its use, and simple structure, reliable operation is processed very convenient again.

The utility model is realized by following technology contents:
This model utility as shown in Figure 1, it is by barrier film (2), controlling rod (4), plunger (or piston) (5), recuperation valve (6), control valve formations such as (7), when the deflection deformation of barrier film (2) front and back, drive controlling rod (4) front-rear reciprocation movement in the cavity (f) of the pump housing (9), there is a slotted hole (a) at controlling rod (4) center, by aperture (b) with have the circular groove (c) that is sizing and link to each other, in the pump housing (9), (A) near circular groove (C) locates, be provided with recuperation valve (6), passing hole channel (d), external system liquid is communicated with cavity (f) in the pump, locate, be provided with control valve (7) at (B) near circular groove (C), passing hole channel (e) communicates the liquid of external system with cavity (f).As can be seen from Fig. 1, when plunger (5) when moving right, also pressurized deflection deformation to the right of barrier film (2), its controlling rod that links to each other distance that also thereupon moves right, when oil mass is excessive, circular groove (c) communicates with passage (e), and liquid is just discharged from control valve (7), thereby has guaranteed that barrier film deflection does not to the right exceed the limit on the right-right-hand limit amount of deflection; When plunger (5) during to left movement, cause the interior negative pressure of the pump housing (9), barrier film is deflection left, drivening rod is also to left movement, when low on fuel, circular groove (C) communicates with passage (d), and liquid just flows into from recuperation valve (6), so just guaranteed that barrier film deflection left also is no more than the limit on the left amount of deflection, reached the purpose of automatic control barrier film maximum deflection distortion.
This invention is far different with the diaphragm pump of Dutch GEHO pump company, see Fig. 2, GEHO company adopts Electromagnetic Control bar (1), Electromagnetic Control probe (2a/2b) mode to control diaphragm deflection, need non-electricity to transform and secondary meter, millisecond or microsecond level signal transmission time difference problem are difficult to solve, it is a kind of mechanism of electromagnetic mode control diaphragm pump diaphragm deflection, complex structure, reliability is relatively poor, and the present invention is machinery control, the problem that no secondary meter and signal transmit belongs to the mechanism that Purely mechanical is controlled the barrier film maximum deflection.
The present invention is with the difference of German LEWA pump company and similar mechanism of Japanese Nikkiso company: confinement plate or preceding confinement plate before and after the back both need increase, be by the distortion of confinement plate restriction barrier film maximum deflection, in case oil mass is too much, can discharge unnecessary oil from safety valve, but the diaphragm cavity internal pressure is higher than head pressure, the barrier film localized stress is excessive, may cause the barrier film permanent deformation or breaks.Too much or not foot phenomenon of oil mass can not take place in the dead point, front and back of barrier film of the present invention and the equal may command of front and back maximum deflection bending.
Below in conjunction with embodiment the utility model is further illustrated; As shown in Figure 1; Barrier film (2) forms with the compacting of known polyurethane rubber or teflon, controlling rod with No. 45 steel surfaces plate the N-P alloy, No. 45 steel car systems of plunger 5 usefulness form after heat treatment, remaining part can process with general carbon steel.
