Abstract
The utility model discloses a plunger piston diaphragm pump comprising a pump body, a diaphragm, a water cavity, a water inlet pipe and a water outlet pipe, wherein the diaphragm and the water cavity are connected with the pump body by connecting bolts; a spring is arranged in the water cavity; the right end of the spring is connected with the diaphragm; the lower part of a connecting pipe is welded and communicated with the water cavity, and the upper part of the connecting pipe is welded and communicated with a water conveying pipe; a group of fins are welded and fixed on the outer wall of the connecting pipe; the left side of the water conveying pipe is connected with the water inlet pipe, and the right side of the water conveying pipe is connected with the water outlet pipe; and a water inlet check valve is arranged on the water inlet pipe, and a water outlet check valve is arranged on the water outlet pipe. The utility model aims at overcoming the defects of traditional plunger piston diaphragm pump and providing the plunger piston diaphragm pump for conveying high-temperature hot water. In the plunger piston diaphragm pump, the high-temperature hot water does not pass through the diaphragm, and the temperature of the diaphragm is low, so that various problems of short service life, cavitation, vibration and the like caused by high temperature are solved.
Description
Technical field:
The utility model relates to a kind of plunger membrance pump, relates to a kind of plunger membrance pump of carrying high-temperature-hot-water in particular.
Background technique:
At present, the water that traditional plunger membrance pump the is carried barrier film of directly flowing through, when carrying high-temperature water, the barrier film temperature is high, and working life is short; When pump absorbs water, form certain vacuum simultaneously around the barrier film, high-temperature water is prone to gasification and produces cavitation, directly influences the use of pump, causes the periodic vibration of pump when serious.
The model utility content:
The purpose of the utility model is in order to overcome the deficiency of traditional plunger diaphragm pump, a kind of plunger membrance pump of carrying high-temperature-hot-water to be provided, and its high-temperature-hot-water is without barrier film, and the barrier film temperature is low.
The technological solution of the utility model is following:
The plunger membrance pump; Comprise the pump housing, barrier film, water cavity, intake pipe and outlet pipe, piston is housed in the pump housing, barrier film is connected with the pump housing through connecting bolt with water cavity; One spring is housed in the said water cavity; The spring right-hand member is connected with barrier film, and a connecting tube bottom is communicated with the water cavity welding, and top is communicated with the conduit pipe welding.
In the technique scheme, fixing one group of fin of welding on the outer wall of said connecting tube.
In the technique scheme, said conduit pipe left side is communicated with intake pipe, and the conduit pipe right side is communicated with outlet pipe, and the intake pipe place is provided with into water one-way valve, and the outlet pipe place is provided with out water one-way valve, the one-way valve and go out water one-way valve and conduit pipe through being threaded of intaking.
The beneficial effect of the utility model is:
The plunger membrance pump of the utility model, it has solved variety of issues such as weak point in working life that traditional plunger diaphragm pump causes because of high-temperature water, cavitation, vibration.The barrier film left side of this plunger membrance pump connects the water cavity that an inside has spring, welding one connecting tube on the water cavity, welding one fin on the outer wall of connecting tube; Water during work in water cavity and the connecting tube only transmits pressure and does not flow; Be delivered to the interior heat of water cavity seldom, simultaneously because the heat sinking function of fin makes barrier film remain low temperature; The barrier film so the water of carrying is not flowed through, the working life of having improved the plunger membrance pump.Around barrier film, can not form vacuum simultaneously, high-temperature water does not produce cavitation, does not influence the use of pump, just can not cause the periodic vibration phenomenon of pump, stable performance, and safe and reliable, cost is low.Simultaneously simple in structure, easy for installation.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation of the utility model.
Embodiment:
The following stated is merely the preferred embodiment of the utility model, is not that scope to the utility model limits.
Embodiment sees accompanying drawing 1, and the plunger membrance pump comprises the pump housing 1, barrier film 3, water cavity 4, intake pipe 8 and outlet pipe 12; In the pump housing 1 piston is housed; Barrier film 3 is connected with the pump housing 1 through connecting bolt 2 with water cavity 4, is set with a spring 5 in the said water cavity 4, and the spring right-hand member is connected with barrier film; One connecting tube, 6 bottoms are communicated with water cavity 4 welding, and connecting tube 6 tops are communicated with conduit pipe 10 welding.
In the technique scheme, fixing one group of fin of welding on the outer wall of said connecting tube.
In the technique scheme; Said conduit pipe 10 left sides are communicated with intake pipe 8, and conduit pipe 10 right sides are communicated with outlet pipe 12, and intake pipe 8 places are provided with into water one-way valve 9; Outlet pipe 12 places are provided with out water one-way valve 11, water inlet one-way valve 9 with go out water one-way valve 11 and conduit pipe 10 through being threaded.
Working procedure: the plunger of plunger pump suction hydraulic oil forms vacuum, and to the hydraulic oil lateral movement, the volume of water cavity 4 one sides becomes the big negative pressure that forms at the acting in conjunction lower diaphragm plate 3 of spring 5, and high-temperature-hot-water gets into conduit pipes 10 through water inlet one-way valve 9; The plunger of plunger pump extruding hydraulic oil, the pressure of hydraulic pressure cavity raises, and barrier film 3 is to the water lateral movement, and the water in water cavity 4 and the conduit pipe 10 are raise by pressure pressure, go out water one-way valve 11 during to certain pressure and open outside conveying high-temperature water; So back and forth constantly outwards carry high-temperature water.Water in water cavity 4 and the connecting tube 6 only transmits pressure and does not flow, and is delivered to the interior heat of water cavity seldom, and 7 thermolysiss of fin of welding on the outer wall of connecting tube 6 simultaneously make barrier film 3 remain low temperature.
