Abstract
The utility model relates to a mechanical driven membrane pump, comprising three parts of a transmission organ, a pump head and route adjusting system, the transmission organ comprises an electric motor, a case, a coupling, a worm, a worm wheel shaft, an eccenter, and a guiding axle; the pump head comprises a pump cover, a membrane, a middle conjoining, an inlet one way valve, and an outlet one way valve; the route adjusting system comprises a limit rod, and adjusting handle. Contrasting with the prior art, the utility model has the advantages of simple structure, convenient operation, low manufacture and maintenance cost, which can fast monitor the membrane failure and so on.
Description
Technical field
The utility model belongs to device for transporting objects, is specifically related to a kind of Mechanical Driven diaphragm pump.
Background technique
At present, along with the continuous development of chemical industry technology, people improve day by day to environmental requirement in addition, require to guarantee not have under many operating modes to leak as the pump of mass transport.At present, the no-leakage pump of technology comparative maturity mainly contains magnetic drive pump, diaphragm pump, peristaltic pump etc.These pumps and valve are through the development of decades, and technology is comparatively ripe.But all there is corresponding narrow limitation in these pumps.
1) the magnetic force driving pump magnetic force driving pump adopts plug-type magnetic structure, realizes the non contact transmission of moment, and change is sealed into static seal, reaches no leakage effect.Because himself structural feature, magnetic drive pump is to small flow and contain granule materials and carry and be not suitable for.
2) the diaphragm pump diaphragm pump adopts hydraulic transmission to promote diaphragm movement, realizes medium transport.Because barrier film separates medium and Sealing, can guarantee that the material of being carried does not have leakage fully.But the pump operation process may cause the hydraulic oil vaporization and can leak to some extent, therefore recharging oil device and means of deflation must be housed, the diaphragm pump structure complexity, and complex operation, processing cost is higher, and maintenance is inconvenient.
The peristaltic pump peristaltic pump mainly relies on rotor rotation to come squeezing tube to reach conveying material, and it can guarantee not have leakage problem fully, so it is widely used in clean environments such as food, medicine, biochemistry, is essentially the laboratory and uses.But its working method has limited its using scope, and it is not suitable for containing solid particle material.
Summary of the invention
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of simple in structure, easy to operate, can leak the Mechanical Driven diaphragm pump that use under the working condition not having.
The purpose of this utility model can be achieved through the following technical solutions: a kind of Mechanical Driven diaphragm pump, comprise driving mechanism, pump head, stroke adjustment system three parts, it is characterized in that described driving mechanism comprises motor, casing, coupling, worm screw, worm gear, worm-wheel shaft, eccentric wheel, the axis of guide; Described pump head comprises pump cover, diaphragm, middle conjuncted, import one-way valve, outlet one-way valve; Described stroke adjustment system comprises limit rod, regulating handle; Described motor links to each other with worm screw by coupling, adorn a cam on the worm-wheel shaft, refill bearing on this cam, the axis of guide is promoted by eccentric wheel, the answer of the axis of guide relies on spring, the to-and-fro motion of the axis of guide promotes the to-and-fro motion of diaphragm, and described stroke adjustment system is adjusted the move distance of the axis of guide by a limit rod.
Also comprise the diaphragm support ring, described diaphragm and diaphragm support ring directly are contained on the axis of guide.
Also comprise the rupture of diaphragm alarm actuating contact, this alarm actuating contact directly is connected with alarm.
Compared with prior art, the utlity model has following advantage:
One, simple in structure.The utility model has been abandoned three control valve units, hydraulic oil and the diaphragm confinement plate of hydraulic diaphragm pump.Optimized structure to a great extent.The stroke adjustment structure is also simplified greatly, makes overall structure more reasonable.
Two, manufacturing and maintenance cost are low.Material and processing cost have been saved in the minimizing of component.The easily damaged parts diaphragm is changed as long as the dismounting pump head just can be backed out diaphragm easily, simplified service procedure.
Three, easy to operate.This model utility is easy to adjust.
Four, set up the rupture of diaphragm alarm actuating contact, can lose efficacy by the fast monitored diaphragm.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of Mechanical Driven diaphragm pump, mainly contain motor 12, casing 1, coupling 11, worm screw 5, worm gear 16, worm-wheel shaft 14, eccentric wheel 17, the axis of guide 7 mutual group become the diaphragm driving mechanism, pump cover 4, middle conjuncted 9, import one-way valve 3, outlet one-way valve 10 have been formed pump head jointly, and limit rod 13, regulating handle 15 have been formed the stroke adjustment system.This embodiment has also possessed rupture of diaphragm alarm actuating contact 2 in addition.
