Abstract
The utility model discloses a pasty fluid pumping stabilizer which comprises a barrel body, wherein one end of the barrel body is closed while the other end is provided with a feeding port, wherein a sliding piston is arranged in the cavity of the barrel body, the barrel body is divided into an inflation cavity close the closed end and a pasty fluid inlet cavity close to the feeding port by the piston, and an inflation valve communicated with the inflation cavity is connected to the barrel body. The pasty fluid pumping stabilizer with the structure has the advantages of long service life, high pressure endurance capability, low manufacturing and maintenance cost and simplicity and convenience in operation.
Description
Technical field
The utility model belongs to paste material high pressure pump feed technique field, relates to a kind of ointment pumping current stabilizer.
Background technology
It is the Novel clean conveying technology that development in recent years is got up that the high pressure remote pipe of paste material is carried.The nucleus equipment of this technology is generally reciprocating displacement pump.When the reciprocating displacement pump pumping mechanism convey materials such as application piston pump, plunger pump, membrane pump, can produce in the outlet of pumping mechanism the pulsation of fluid, the impact that this pulsation produces has aggravated the wearing and tearing of pipeline, also causes the vibrations of pipeline simultaneously and then produces adverse consequences.Be head it off, also there are the devices such as some diaphragm type expansion tanks and flexible pipe energy disperser to be applied in engineering practice in this technical field, but because barrier film and flexible pipe are difficult to bear high frequency time flexural deformation, cause that service life is short, replacement cost is high and be difficult to bear up to defectives such as the above high pressure of 5MPa.
The utility model content
The technical problems to be solved in the utility model is for above-mentioned deficiency, provides a kind of long service life and compression capability strong ointment pumping current stabilizer.
In order to solve the problems of the technologies described above, the utility model provides a kind of ointment pumping current stabilizer of following structure, comprise that an end sealing other end is provided with the cylindrical shell of inlet point, its constructional feature is to be provided with in cylinder lumen slidably piston, and piston is separated into cylinder lumen near the inflatable chamber of cylindrical shell closed end and the lotion of close inlet point and enters the chamber; Be connected with the charge valve that is communicated with inflatable chamber on cylindrical shell.
For the ease of reading the gas pressure value in inflatable chamber, be connected with the compression indicator that is communicated with inflatable chamber on described cylindrical shell.
For the ease of carrying delivery side of pump or be connected with the feed end of delivery duct with slurry, be connected with flange on the feed end of described cylindrical shell.
For the ease of assembling or maintenance, the sealing of described cylindrical shell closed end is by being screwed onto the end cap realization of cylindrical shell end.
In order to alleviate piston weight, be provided with cavity in described piston.
In order to obtain better sealing effectiveness, described piston is provided with the two seals circle.
In order to make piston keep the not deflection of moving in cylindrical shell, described piston is provided with mud-scraping ring and the guide ring between the two seals circle near inlet point.Mud-scraping ring also can strike off the lotion that is attached on cylinder inboard wall except playing the guiding role.
Occupation mode of the present utility model is as follows: the cylindrical shell inlet point is carried delivery side of pump or is communicated with the feed end of delivery duct with slurry, be filled with proper amount of gas by charge valve in inflatable chamber, such as air, nitrogen or carbon dioxide etc., the amount of being filled with of gas will be satisfied the pressure of inflation intracavity gas lower than slurry transmission pump delivery pressure; After completing, above-mentioned work can use.
Principle of work of the present utility model is as follows: when the material with fluctuation of pressure acts on piston by inlet point of the present utility model, piston passes to gas in inflatable chamber to this fluctuation of pressure, utilize the compressibility of gas to come the fluctuation of pressure of suction line, play the effect that significantly reduces fluctuation of pressure, make system pressure remain on a stable scope.
In sum, for the compressive deformation body of barrier film expansion tank and flexible pipe energy disperser, the utility model is realized the buffering of pressure by the change of piston position, thus make the utlity model has that long service life, voltage endurance capability are high, manufacturing and maintenance cost is low and operation is easier advantage.
Description of drawings
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the ointment pumping current stabilizer comprises cylindrical shell 1, cylindrical shell 1 one ends are realized sealing by the end cap 11 that is spirally connected thereon, cylindrical shell 1 other end opens wide and forms inlet point 12, be connected with flange 7 on the feed end of cylindrical shell 1, seal ring 15 is housed on the end face of flange 7, flange 7 be used for be located at the outlet of slurry transmission pump on or the barretter 14 that is located on the delivery duct feed end be connected.Be provided with slidably piston 2 in cylindrical shell 1 inner chamber, be provided with cavity 13 in piston 2, the outer peripheral face of piston 2 is provided with two seals circle 8, be provided with near the mud-scraping ring 9 of inlet point 12 and be provided with guide ring 10 between two seals circle 8.Piston 2 is separated into cylindrical shell 1 inner chamber near the inflatable chamber 3 of end cap 11 and the lotion of close inlet point 12 and enters chamber 4.Be connected with the charge valve 5 that is communicated with inflatable chamber 3 on cylindrical shell 1 and be connected with the compression indicator 6 that is communicated with inflatable chamber 3.
