Description
Technical field
The present invention relates to a kind of hydraulic air-free pump for equipment spraying.
Background technology
Existing air-free pump is low due to movement travel, thus the service life that the times of exercise increasing sealing member makes it shortens, and structure is complicated, heavier-weight, can produce relatively high noisy in use, it is therefore necessary to improve.
Summary of the invention
The invention aims to solve above-mentioned the deficiencies in the prior art and provide a kind of compact structure, noise is low, increases the hydraulic air-free pump of flow.
To achieve these goals, hydraulic air-free pump designed by the present invention, including the pump housing, piston component, pedestal and suction assembly, the pump housing is connected with piston component, piston component is connected by pedestal with suction assembly, described piston component includes pull bar, the second pull-rod nut, piston, piston seal and spells cap, piston, piston seal and spelling cap form one and seal space, pull-rod spring and the first pull-rod nut it is provided with in piston, first pull-rod nut is connected with pull bar by pull-rod spring, and the other end of pull bar and the second pull-rod nut connect and be positioned at the pump housing.
The hydraulic air-free pump that the present invention obtains, operationally so that it is movement travel is greatly improved thus decreases the times of exercise of sealing member and extend service life, and compact structure, noise is low, on the premise of not changing spraying property, greatly improves the flow of product.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of embodiment 1；
Fig. 2 is the sectional view of embodiment 1.
In figure: silently 1, the pump housing 2, piston component 3, oil inlet pipe 4, diverter 5, suction assembly 6, pedestal the 7, first pull-rod nut 8, pull-rod spring 9, pull bar 10, piston 11, piston seal 12, spell cap the 13, second pull-rod nut 14, plunger 15.
Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Embodiment 1:
Such as Fig. 1, shown in 2, the hydraulic air-free pump that the present embodiment is provided, including the pump housing 2, piston component 3, pedestal 7 and suction assembly 6, the pump housing 2 is connected with piston component 3, piston component 3 is connected by pedestal 7 with suction assembly 6, described piston component 3 includes pull bar 10, second pull-rod nut 14, piston 11, piston seal 12 and spelling cap 13, piston 11, piston seal 12 and spelling cap 13 form one and seal space, pull-rod spring 9 and the first pull-rod nut 8 it is provided with in piston 11, first pull-rod nut 8 is connected with pull bar 10 by pull-rod spring 9, the other end and second pull-rod nut 14 of pull bar 10 connect and are positioned at the pump housing 2.
During work, hydraulic oil liquid is flowed into from the A mouth of oil inlet pipe 4 by hydraulic pump, first flow at C, 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 being arranged on the pump housing 2 one end, after pull bar 10 top is to silently 1, hydraulic oil liquid is flowed at B from oil inlet pipe 4, part the second pull-rod nut 14 is made to move to silently 1 direction, diverter 5 is connected with the pump housing 2 and contacts with the second pull-rod nut 14 surface, hydraulic oil liquid is then flowed at G by diverter 5 and makes part piston 11 move down, thus produce linear reciprocating motion.Driving plunger 15 and suction assembly 6 to carry out linear reciprocating motion by the motion of piston 11, raw material is drawn into generation pressure at H and is discharged by discharging opening by recycling check valve technology.When not working or oil liquid pressure arrives to a certain degree, fluid can be back to hydraulic pump at F, so can be on the premise of not changing spraying property, greatly improve the flow of product, also make its movement travel be greatly improved thus decrease the times of exercise of sealing member and extend service life, and simple in construction, lightweight, also reduce noise.
