Abstract
The invention discloses a hydraulic air-free pump for equipment painting. The hydraulic air-free pump comprises a pump body, a piston module, a base seat and a sucking module. The pump body is connected with the piston module, the piston module is connected with the sucking module through the base seat and comprises a draw bar, a second draw bar nut, a piston, a piston seal and an assembling cap, wherein the piston, the piston seal and the assembling cap form a closed space; a draw bar spring and a first draw bar nut in arranged inside the piston, the first draw bar piston is connected with the draw bar through the draw bar spring, and the other end of the draw bar is connected with the second draw bar nut and arranged inside the pump body. During the work of the hydraulic air-free pump, the motion stroke of the hydraulic air-free pump is greatly improved, accordingly the number of movement times of the seal is reduced and the service life of the seal is improved; meanwhile, the hydraulic air-free pump is small and cleverish in structure, low in noise and capable of greatly improving the product flow under the premise of not changing the painting performance.
Description
Technical field
The present invention relates to a kind of hydraulic pressure for the equipment spraying without air pump.
Background technique
Existing without air pump because movement travel is low, thereby the times of exercise that has increased Sealing shortens its working life, and complex structure, weight is heavier, can produce than high noisy in use, therefore is necessary to be improved.
Summary of the invention
The objective of the invention is provides a kind of structure small and exquisite in order to solve above-mentioned the deficiencies in the prior art, and noise is low, and the hydraulic pressure of augmented flow is without air pump.
To achieve these goals, the designed hydraulic pressure of the present invention is without air pump, comprise the pump housing, piston assembly, pedestal and suction assembly, the pump housing is connected with piston assembly, piston assembly is connected by pedestal with the suction assembly, described piston assembly comprises pull bar, the second pull-rod nut, piston, piston seal and spelling cap, piston, piston seal and spelling cap form a seal space, be provided with pull-rod spring and the first pull-rod nut in piston, the first pull-rod nut is connected with pull bar by pull-rod spring, the other end of pull bar is connected with the second pull-rod nut and is positioned at the pump housing.
The hydraulic pressure that the present invention obtains is without air pump, when work, thereby makes its movement travel times of exercise that has reduced Sealing that is greatly improved extend working life, and structure is small and exquisite, noise is low, under the prerequisite that does not change spraying property, has improved greatly the flow of product.
The accompanying drawing explanation
Fig. 1 is embodiment 1 overall structure schematic diagram;
Fig. 2 is embodiment 1 sectional view.
In figure: silently 1, the pump housing 2, piston assembly 3, oil inlet pipe 4, commutator 5, suction assembly 6, pedestal 7, the first pull-rod nut 8, pull-rod spring 9, pull bar 10, piston 11, piston seal 12, spell cap 13, the second pull-rod nut 14, plunger 15.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
Embodiment 1:
As Fig. 1, shown in 2, the hydraulic pressure that the present embodiment provides is without air pump, comprise the pump housing 2, piston assembly 3, pedestal 7 and suction assembly 6, the pump housing 2 is connected with piston assembly 3, piston assembly 3 is connected by pedestal 7 with suction assembly 6, described piston assembly 3 comprises pull bar 10, the second pull-rod nut 14, piston 11, piston seal 12 and spelling cap 13, piston 11, piston seal 12 and spelling cap 13 form a seal space, be provided with pull-rod spring 9 and the first pull-rod nut 8 in piston 11, the first pull-rod nut 8 is connected with pull bar 10 by pull-rod spring 9, the other end of pull bar 10 is connected with the second pull-rod nut 14 and is positioned at the pump housing 2.
During work, hydraulic oil liquid flows into from the A mouth of oil inlet pipe 4 by oil hydraulic pump, first flow into the C place, drive the first pull-rod nut 8, pull-rod spring 9, pull bar 10, piston 11, piston seal 12 and spelling cap 13 move to silently 1 direction that is arranged on the pump housing 2 one ends, when pull bar 10 top to silently after 1, hydraulic oil liquid flow into B from oil inlet pipe 4, part the second pull-rod nut 14 is moved to 1 direction silently, commutator 5 is connected with the pump housing 2 and contacts with the second pull-rod nut 14 surfaces, hydraulic oil liquid flow into the G place by commutator 5 moves down part piston 11, thereby generation linear reciprocating motion.Motion by piston 11 drives plunger 15 and suction assembly 6 carries out linear reciprocating motion, and recycling one-way valve technology is drawn into H place generation pressure by raw material and discharges by discharge port.When do not work or oil liquid pressure while arriving to a certain degree fluid can be back to oil hydraulic pump from F, like this can be under the prerequisite that does not change spraying property, improved greatly the flow of product, thereby also make its movement travel times of exercise that has reduced Sealing that is greatly improved extend working life, and simple in structure, lightweight, also reduced noise.
