Abstract
The utility model discloses an anti-leaking high-pressure inclined disc pump. The anti-leaking high-pressure inclined disc pump comprises a pump cover, wherein a water inlet valve, a water outlet valve and an exchanging valve communicated with the water inlet valve and the water outlet valve are arranged inside the pump cover. The water inlet valve is communicated with a liquid inlet cavity. A plunger doing reciprocating motions is arranged inside the exchanging cavity. A sealing ring seat is arranged on an outer ring of the plunger in a sleeved mode. The sealing ring seat is fixedly arranged on the pump cover. A main sealing assembly is arranged on the outer ring of the plunger in a sleeved mode. The sealing ring seat is provided with an auxiliary sealing ring and a first hole. The pump cover is provided with a second hole communicated with the liquid inlet cavity. The first hole is communicated with the second hole. Due to a double-sealing structure, the anti-leaking high-pressure inclined disc pump radically avoids the phenomenon of water leakage existing in the single-sealing structure before, ensures that the first hole and the second hole are communicated with the liquid inlet cavity to ensure that water leaked out from the main sealing assembly flows back to the liquid inlet cavity.

Background technique
Traditional swash plate pump comprises outlet valve of an inlet valve, and with the inverting chamber that is connected with them, be provided with the plunger that moves reciprocatingly in inverting chamber, when plunger towards leaving inverting chamber when motion, be negative pressure state in inverting chamber, this moment, outlet valve was closed, and inlet valve is opened, and the low-pressure water of admission chamber is sucked in inverting chamber by inlet valve; Towards entering inverting chamber when motion, be high pressure conditions when plunger in inverting chamber, this moment, inlet valve was closed, and outlet valve is opened, and the high pressure water in inverting chamber is pressed into hyperbaric chamber by outlet valve.Completed like this one and water has been uprised the complete cycle of pressure by low pressure.
because plunger can form high pressure to the extruding of water, therefore the sealing between plunger and inverting chamber has determined the effect of high pressure, for the sealing that improves between plunger and inverting chamber generally can be installed seal ring between plunger and inverting chamber, by finding out in the reciprocating process of plunger that the sealing circle has the time of half to be in high pressure conditions, it is subject to the squeezing action of high pressure water, and plunger surface is produced very large enclasping force, due to the motion of plunger reciprocal straight line motion still not, but also can rotatablely move and slight the swing, therefore have all the time a small amount of seepage at plunger surface and seal ring junction, these water might stockpile at the opposite side of inverting chamber, and may drain to outside the pump housing.
Summary of the invention
The utility model is not enough for prior art, provides a kind of and can prevent that sealing drains to a kind of anti-leak high-pressure swash-plate pump in the pump housing outside.
in order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of anti-leak high-pressure swash-plate pump, comprise pump cover, be provided with inlet valve in described pump cover, outlet valve and the inverting chamber that is communicated with them, described inlet valve is communicated with admission chamber, be provided with the plunger that moves reciprocatingly in described inverting chamber, described plunger outer ring sleeve is provided with packing holder, described packing holder is fixedly installed on pump cover, described plunger outer ring sleeve is provided with main sealing assembly, be provided with secondary seal ring on described packing holder, be provided with the first hole on described packing holder, be provided with the second hole on described pump cover, described the second hole is communicated with admission chamber, described the first hole is communicated with described the second hole.It is to be in high pressure conditions that main sealing assembly has half the time, and it is subject to the squeezing action of high pressure water, and plunger surface is produced very large enclasping force.Due to the motion of plunger linear reciprocating motion still not, but also can rotatablely move and slight the swing, therefore always have the Trace water film in plunger surface and main sealing assembly junction and leaked in the first hole by inverting chamber.Secondary seal ring is in low-pressure state all the time in whole cyclic process, so the sealing between secondary seal ring and plunger surface is fine, can prevent from continuing seepage outwardly from the water of main sealing assembly seepage.This double sealing structure has fundamentally been evaded the phenomenon that leaking appears in single sealing configuration in the past, and the first hole, second hole and admission chamber are communicated with make the current that ooze out from main sealing assembly get back to admission chamber.
In technique scheme, preferred, described main sealing assembly comprises support ring, primary seal circle and seal joint.Seal joint plays and makes the stressed stepless action of primary seal circle; Support ring plays and supports the primary seal circle, prevents under high pressure root generation of primary seal circle squeeze crack, twists off effect, comprehensively improves the sealing effect of main sealing assembly.
In technique scheme, preferred, be provided with O shape circle between described packing holder and pump cover, improve the sealing between packing holder and pump cover.
The utility model compared with prior art, have following beneficial effect: the utility model has fundamentally evaded by this double sealing structure the phenomenon that leaking appears in single sealing configuration in the past, and the first hole, second hole and admission chamber are communicated with make the current that ooze out from main sealing assembly get back to admission chamber.
