Abstract
The utility model relates to a metering pump, and aims at providing a hydraulic diaphragm type reciprocating pump with a function of membrane breakage alarm. The reciprocating pump comprises a pump head, a membrane and a rear membrane plate which are sequentially installed, wherein the membrane comprises two stacked monolayer membranes; an annular guide ring is arranged between the two monolayer membranes; and the guide ring is connected with a pressure sensor. When any one of the membranes is broken, high-pressure oil enters the guide ring along a clearance between the two monolayer membranes and triggers the pressure sensor to prompt users to prepare for replacement. By adopting the design of the two monolayer membranes, the metering pump can continuously operate even if one membrane is broken. The utility model has simple technology structure, wide practicability and great promotion prospects.
Description
Technical field
The utility model relates to a kind of metering pump.More particularly, the utility model relates to a kind of hydraulic diaphragm-type reciprocating pump with function of diaphragm breakage alarm.
Background technique
Present hydraulic diaphragm metering pump, the Chinese patent application of once submitting to such as the model utility people of this case application " interior circulating pressure circulation ultra high pressure hydralic diaphram type metering pump " (CN200510050717.8), " high-pressure hydraulic diaphragm metering pump " (CN200610154976.X), " hydraulic diaphragm metering pump " with front-located mode cuticula plate structure (CN200510061366.0) described in, the diaphragm that is adopted in its pump head is single-iris.Because hydraulic diaphragm-type reciprocating pump generally is used for the conveying of high-pressure medium, under plunger to-and-fro motion effect, the running of diaphragm TERM DEFORMATION can cause membrane material fatigue, cause metering pump not play a role as diaphragm breakage, must cause medium to carry, have serious consequences for the production run of tooling.
The model utility content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of hydraulic diaphragm-type reciprocating pump with function of diaphragm breakage alarm is provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions.
The utility model provides a kind of hydraulic diaphragm-type reciprocating pump with function of diaphragm breakage alarm, comprises pump head, diaphragm and the back lamina membranacea installed successively; Described diaphragm is made up of two individual layer diaphragms that stack; Between two individual layer diaphragms, the guide ring of an annular is set; Guide ring is connected with a pressure transducer.
As a kind of improvement, the truncation surface of described guide ring is " mountain " font, and middle outstanding position is stretched between two individual layer diaphragms, and outstanding position, both sides surrounds the outer rim of two individual layer diaphragms.
As a kind of improvement, cuticula plate and back cuticula plate before establishing respectively on described pump head and the back lamina membranacea, the guide rod of preceding cuticula plate is arranged in the guide rod through hole at pump head middle part, and the guide rod of back cuticula plate is arranged in the guide rod through hole at lamina membranacea middle part, back.
As a kind of improvement, described pressure transducer is connected to warning device by signaling line.
Compared with prior art, the beneficial effects of the utility model are:
1, when any one diaphragm breaks, high pressure oil enters guide ring along the gap between two individual layer diaphragms, triggers the pressure transducer that joins with guide ring; Pressure transducer sends a signal to warning device, can point out the user to prepare to change.
2, the design of two individual layer diaphragms, even if some rupture of diaphragm have taken place, the still sustainable operation of metering pump also is unlikely to cause technology to generate the stoppage in transit of breaking down at once, operator have time enough to take standby technological operation scheme, can continue to use after to the diaphragm maintenance update.
3, product process structure of the present utility model is simple, has extensive practicability, has great popularizing prospect.
Description of drawings
Fig. 1 is the longitudinal profile structural representation that has the hydraulic diaphragm-type reciprocating pump of function of diaphragm breakage alarm among the utility model embodiment.
Embodiment
With reference to the accompanying drawings, below the utility model is described in detail.
The hydraulic diaphragm-type reciprocating pump that has function of diaphragm breakage alarm in the present embodiment comprises pump head 1, diaphragm and the back lamina membranacea 2 installed successively.Cuticula plate 7 and back cuticula plate 8 before establishing respectively on pump head 1 and the back lamina membranacea 2, the guide rod of preceding cuticula plate 7 is arranged in the guide rod through hole at pump head middle part, and the guide rod of back cuticula plate 8 is arranged in the guide rod through hole at lamina membranacea middle part, back.
Described diaphragm is made up of individual layer diaphragm 3 that stacks and individual layer diaphragm 4; Between individual layer diaphragm 3 and individual layer diaphragm 4, the guide ring 5 of an annular is set.Guide ring is connected with a pressure transducer 6, and pressure transducer 6 is connected to warning device by signaling line.
The truncation surface of guide ring 5 is " mountain " font, and middle outstanding position is stretched between individual layer diaphragm 3 and the individual layer diaphragm 4, and the outstanding position on both sides surrounds the outer rim of individual layer diaphragm 3 and individual layer diaphragm 4.
The main cause of breaking of diaphragm is that diaphragm material fatigue under long-term operating mode causes, and does not therefore generally have the situation appearance that two diaphragms break simultaneously.When any one diaphragm broke, the high pressure oil in its outside entered guide ring along the gap between two individual layer diaphragms, triggered the pressure transducer that joins with guide ring; Pressure transducer sends a signal to warning device again, can point out the user to prepare to change.Because two individual layer diaphragms are arranged, even if some rupture of diaphragm have taken place, the still sustainable operation of metering pump also is unlikely to cause technology to generate the stoppage in transit of breaking down at once, operator have time enough to take standby technological operation scheme, can continue to use after to the diaphragm maintenance update.
At last, it is also to be noted that what more than enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
