Abstract
The invention discloses a high-pressure pump assembly for an airless sprayer which is reliable in operation, long in service life and saved in manufacturing cost. The high-pressure pump assembly for an airless sprayer comprises an upper pump seat, a lower pump seat connected with the upper pump seat, and piston rods disposed in the upper pump seat and the lower pump seat; a material storage cylinder is disposed at the lower end of the lower pump seat; an output joint is disposed at one side of the upper pump seat; a suction valve body is disposed on the lower end part of the material storage cylinder; the end parts of the piston rods can stretch into the material storage cylinder; the end parts of the piston rods are hermetically matched with the inner wall of the material storage cylinder; a sealing ring is disposed on the inner circumference of the material storage cylinder; and the inner circumference of the sealing ring is hermetically matched with the outer circumferences of the piston rods. The high-pressure pump assembly for an airless sprayer disclosed by the invention is suitable for an airless sprayer.
Description
Technical field
The present invention relates to a kind of airless sprayer, relate in particular to a kind of high-pressure pump assembly that is used on the airless sprayer.
Background technology
High pressure airless spray equipment utilizes high-pressure plunger pump that coating is pressurized to 3000PSI (210kg/cm), and the coating that obtains high pressure is transported to spray gun through high-pressure hose, forms atomizing via the nozzle release pressure, thereby forms fine and close coating at surface of wall.Because the coating atomizing does not need compressed air, so be called airless spraying.High pressure airless spray equipment under the effect of gas, makes the piston up-down in the cylinder when work; Paint medium gets into from sucking valve body, and successively through coating cylinder, pump seat, the air pressure that is produced by cylinder extrudes the coating in the coating cylinder through out splice going splice; Because the piston rod that is connected with piston needs to keep being sealed and matched with coating cylinder casing wall, thereby the piston rod end is provided with multiple-sealed ring usually, because joint ring need frequently contact with coating cylinder casing wall; Obscission takes place easily; Cause fluctuation of service, influence coating quality, even produce pull-cylinder phenomena; Simultaneously owing to be full of coating in the coating cylinder; Under the extruding of piston rod end, coating cylinder casing wall is easy to generate wearing and tearing, thereby the coating inside wall of cylinder need adopt case hardening to handle; Cause cost to increase; And common application life is shorter, and is especially when inorganic nature such as carrying out the epoxy zinc-rich lacquer is coated with lacquer operation, all the more so.
Summary of the invention
The technical problem that the present invention will solve provides the airless sprayer that a kind of reliable, long service life, manufacturing cost economize and uses the high-pressure pump assembly.
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme:
The following pump seat that the present invention includes upper pump seat, is connected, be located at the interior piston rod of upper pump seat and following pump seat with upper pump seat; Said pump seat lower end down is provided with accumulator, and said upper pump seat one side is provided with out splice going splice, and said accumulator bottom is provided with the suction valve body; Said piston rod end can be stretched in the accumulator; Said piston rod end cooperates with the accumulator inner wall sealing, week is provided with sealing ring in the said accumulator, and week is sealed and matched with the piston rod periphery in the said sealing ring.
As preferably, in the said accumulator week no hard coat.
As preferably, be provided with cavity in the middle of said piston rod the latter half, said cavity upper end is provided with one way valve, and cross through hole is established in said one way valve top, and said cross through hole is connected with out splice going splice.
As preferably, be provided with one way valve above the said suction valve body.
The present invention compared with prior art has following obvious advantage and beneficial effect:
1, reliable, long service life.Because piston rod end of the present invention is not provided with joint ring, thereby avoids the generation of joint ring obscission, and week sealing ring is set in the employing accumulator, can effectively improves application life.
2, manufacturing cost is economized.Because all no hard coats in the accumulator of the present invention, thereby can save manufacturing cost.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
Shown in accompanying drawing: the present invention includes upper pump seat 1, the following pump seat 2 that is connected with upper pump seat 1, be located at the piston rod 3 in upper pump seat 1 and the following pump seat 2, following pump seat 2 lower ends are provided with accumulator 5, and upper pump seat 1 one sides are provided with out splice going splice 6; Accumulator 5 bottoms are provided with and suck valve body 7, and piston rod 3 ends can be stretched in the accumulator 5, and piston rod 3 ends cooperate with accumulator 5 inner wall sealings; The accumulator 5 interior sealing rings 8 that are provided with in week, week is sealed and matched with piston rod 3 peripheries in the sealing ring 8, all no hard coats in the accumulator 5; Piston rod 3 peripheries do not have joint ring; Be provided with cavity 9 in the middle of piston rod 3 the latter halfs, cavity 9 upper ends are provided with one way valve 10, and cross through hole 11 is established in one way valve 10 tops; Cross through hole 11 is connected with out splice going splice 6, sucks valve body 7 tops and is provided with one way valve 12.
The present invention is when work, when moving upward under the effect of piston rod 3 at piston, owing to form negative pressure in the accumulator 5; Thereby coating gets into from sucking valve body 7; Enter in the accumulator 5 through one way valve 12, and when moving downward under the effect of piston rod 3 at piston, under the extruding of piston rod 3; Coating in the accumulator 5 gets in the cavity 9, and exports from out splice going splice 6 through one way valve 10 and cross through hole 11.
