The specific embodiment
Shown in Figure 1 is a kind of embodiment of basic model, it mainly is made up of the continuous feed mechanism 3 of normal pressure slurry and high-pressure abradant jet current membrane pump 1 two parts, connect by slurry suction inlet pipeline 4 between two parts, pressure duct 5 is connected between high-pressure abradant jet current membrane pump 1 and the nozzle 6, described high-pressure abradant jet current membrane pump 1 also with leakage fluid case 2 with on put fluid infusion case 7 and be connected.
Described high-pressure abradant jet current membrane pump 1 has the pump housing 1A of two cavitys that are interconnected, and the pump housing plays and bear pressure, surrounds pressure chamber and support cavity volume, provides functions such as other component installation locations.Wherein, be provided with piston 1B in the cavity, be provided with potted component 1D between the sliding contact surface of pump housing 1A and piston 1B.The center fixed of another cavity has flexible diaphragm 1E, and this cavity is divided into high drive sap cavity 1J with this barrier film and high pressure is driven sap cavity 1H.In high pressure is driven the chamber of sap cavity 1H, be provided with an end and be supported in pump housing inwall, the back-moving spring 1G that the other end is connected with flexible diaphragm 1E core, this cavity also is communicated with slurry suction inlet pipeline 4 by unidirectional feed liquor valve 1F, is communicated with pressure duct 5 by unidirectional liquid valve 1I.Have the fluid infusion mouth and be equipped with on the wall of cavity of piston 1B, connect by fluid infusion check valve 1K and put fluid infusion case 7, the cecum of this cavity also has and leaks leakage fluid dram 1C, and is communicated with leakage fluid case 2.
The continuous feed mechanism 3 of described normal pressure slurry has normal pressure slurry box 3A, be provided with agitator 3B in it, agitator is by motor or fluid motor-driven, abrasive material in the slurry in the slurry box and water are mixed, one end of described slurry suction inlet pipeline 4 stretches into the bottom of normal pressure slurry box 3A, the slurry that mixes sucks high-pressure abradant jet current membrane pump 1 by slurry suction inlet pipeline 4, realizes the function of slurry supply.
Described flexible diaphragm 1E has fluid partitioning, transmits functions such as pressure, breakage alarm, be to form with the multilayer rubber compacting, the material of the both sides outer surface layer of this sandwich construction adopts acrylonitrile-butadiene rubber, accompany the conductive rubber layer of mutually insulated in it, conductive rubber layer is drawn the pump housing by lead-in wire and is connected the two ends of warning electric control gear 1L.When barrier film generation disrepair phenomenon, owing to there is water to pass through damaged section, so the resistance between the conductive rubber layer will reduce rapidly, and warning electric control gear 1L detects this resistance variations and reports to the police or make whole device out of service.
The opening pressure of described fluid infusion check valve 1K is greater than the opening pressure of unidirectional feed liquor valve 1F, and the pressure reduction between the two is between 0.04MPa-0.06MPa.
Shown in Figure 2 is another kind of embodiment, when the needs automation is supplied with continuously, can also increase abrasive material loader 3C, normal pressure slurry box 3A is aimed in its outlet, electric control gear 3D and the electrically-controlled valve 3E in addition that are connected with the abrasive material loader, the water inlet pipe 3F that inserts from the outside is located at the top of normal pressure slurry box 3A behind electrically-controlled valve 3E.The flow of water is by electric control gear 3D Collaborative Control among the rate of feed of abrasive material loader 3C and the water inlet pipe 3F, makes that the ratio of abrasive material and water keeps constant within the specific limits in the slurry of normal pressure slurry box 3A the inside.
The course of work of the present invention is: 1) prepare slurry, before system brought into operation, the water and the abrasive material that have prepared ratio among the normal pressure slurry box 3A stirred under the effect of agitator 3B, and becoming can be by the slurry of high-pressure abradant jet current membrane pump 1 suction.If because the operation of system, slurry reduces gradually, when needing to add, abrasive material and water proportionally need be mixed earlier, to going in the normal pressure slurry box 3A, change suddenly then with the composition that prevents slurry, the quality and the speed of cutting is exerted an influence.When the needs automation is supplied with continuously, then install according to structure shown in Figure 2.
2) high-pressure abradant jet current membrane pump 1 sucks the process of slurry, system brings into operation, and when the piston 1B of pump moved left under external force, it is big that the volume of high drive sap cavity 1J becomes, therefore pressure reduces, and makes high pressure be driven the interior pressure of sap cavity 1H greater than the pressure in the high drive sap cavity 1J.The pressure differential promotion flexible diaphragm 1E that high pressure is driven between sap cavity 1H and the high drive sap cavity 1J is out of shape (flexible diaphragm 1E is inhaled to left by the piston 1B of pump in other words) left.Like this, the pressure that high pressure is driven in the sap cavity 1H will reduce owing to the expansion of this chamber internal volume, thereby is lower than extraneous atmospheric pressure.Under external atmospheric pressure and high pressure are driven pressure differential effect between pressing in the sap cavity 1H, slurry in the normal pressure slurry box 3A flows in high pressure is driven sap cavity 1H by slurry suction inlet pipeline 4 and unidirectional feed liquor valve 1F, thereby has filled owing to flexible diaphragm 1E is out of shape the volume-variation that causes left.
3) high-pressure abradant jet current membrane pump 1 high pressure is discharged the process of slurry, when the piston 1B of pump moves to the right under external force, the volume of high drive sap cavity 1J diminishes, so pressure increases, and makes that the pressure in the high drive sap cavity 1J is driven pressure in the sap cavity 1H greater than high pressure.The pressure differential promotion flexible diaphragm 1E that high drive sap cavity 1J and high pressure are driven between the sap cavity 1H is out of shape (flexible diaphragm 1E is pressed to right-hand by the piston 1B of pump in other words) to the right.Like this, the pressure that is driven in the sap cavity 1H of high pressure will increase owing to dwindling of this chamber internal volume.Because slurry can be counted as can not compressed fluid, therefore the slurry in this cavity volume is just by unidirectional liquid valve 1I and pressure duct 5, under high pressure be pushed to nozzle 6 places, produce high-pressure abradant jet current, just can aim at the workpiece or the material that will cut or clean, clean, eliminate rust or operation such as drilling, cutting.
4) leakage and the additional process of liquid in the high drive sap cavity 1J of high-pressure abradant jet current membrane pump 1, when the piston 1B of pump moves to the right under external force (high pressure is discharged in the process of slurry), because the pressure of liquid is higher in the high drive sap cavity 1J, and because the potted component 1D between piston and the housing is movable sealing, so more or less, understand some liquid in high drive sap cavity 1J, infiltrate the sap cavity on the piston 1B left side of pump through the potted component 1D between piston and the housing, leakage leakage fluid dram 1C by pump flows out the high-pressure abradant jet current membrane pump, enters leakage fluid case 2.When above-mentioned seepage process accumulation is more, because the liquid volume in the high drive sap cavity 1J reduces, cause flexible diaphragm 1E to be forced to depart from the normal position left, change with the liquid volume in the compensation high drive sap cavity 1J.To be forced to depart from the normal position left more and more far away along with flexible diaphragm 1E, and the pulling force of flexible diaphragm back-moving spring 1G is just increasing, will cause the pressure in the high drive sap cavity 1J to reduce; When the pressure ratio external atmosphere pressure in the high drive sap cavity 1J was much lower, fluid infusion check valve 1K will be opened by this pressure reduction, and liquid will flow into high drive sap cavity 1J from putting fluid infusion case 7, the reducing of the liquid volume that causes because of seepage with compensation.
