Background technology
Under some equipment needs to carry out fluid environment at present, hydrophobic metal surface abrasion resistance is tested, existing conventional equipment is similar to angle of rake equipment substantially, can only measure by single flow velocity, but the flow rate of liquid in existing actual environment changes at any time, because flow velocity is different, also be vicissitudinous to the erosion of metal surface, so existing equipment cannot record hydrophobic metal surface abrasion resistance experiment under various environment accurately.
Summary of the invention
The purpose of this utility model is to provide the adjustment of a kind of air pressure by pneumatic cylinder and converts the integrated form adjustable speed drop generating device of regulator solution drip speed.
Pneumohydraulic pressure-cylinder of the present utility model is arranged on upper junction plate, is connected between upper junction plate with lower connecting plate by back-up block, and lower connecting plate is connected with fluid cylinder, and fluid cylinder lower end has been threaded connection drop and has formed cylinder cap; The piston rod front end of pneumohydraulic pressure-cylinder is placed in the cavity of upper junction plate, lower connecting plate and back-up block formation, and this cavity communicates with fluid cylinder, is provided with packed-piston head in piston rod end, and the external diameter of packed-piston head is identical with fluid cylinder internal diameter; Fluid tank is communicated with fluid cylinder by pipeline; Formed on cylinder cap at drop and have droplet-shaped member, droplet-shaped member has through drop extrusion; The frame that drop is formed below cylinder cap is provided with sample support axle, and the sample support axle other end stretches out frame and fastening by fastening bolt, and sample support axle has slide, and sample is placed on slide.
On sample support axle of the present utility model, cover has angle indicator.
The utility model is provided with droplet counter in frame.
The utility model structure is simple, easy to use, and the utility model is by the pressure of adjustable pressure cylinder, thus adjustment is to the liquid conversion pressure of fluid cylinder inside, makes the liquid extruded velocity of its inside variable adjustable.The utility model has integration: device can provide the droplet cluster with certain impact speed (pressure), and impacts super hydrophobic surface; Intelligent: device has tally function, energy accurate recording impacts the amount of droplets of super hydrophobic surface.

Detailed description of the invention
Pneumohydraulic pressure-cylinder 1 of the present utility model is arranged on upper junction plate 18, is connected between upper junction plate 18 with lower connecting plate 15 by back-up block 17, and lower connecting plate 15 is connected with fluid cylinder 3, and fluid cylinder 3 lower end has been threaded connection drop and has formed cylinder cap 5; Piston rod 2 front end of pneumohydraulic pressure-cylinder 1 is placed in the cavity of upper junction plate 18, lower connecting plate 15 and back-up block 17 formation, and this cavity communicates with fluid cylinder 3, be provided with packed-piston head 16 in piston rod 2 end, the external diameter of packed-piston head 16 is identical with fluid cylinder 3 internal diameter; Fluid tank 7 is communicated with fluid cylinder 3 by pipeline; Formed on cylinder cap 5 at drop and have droplet-shaped member 14, droplet-shaped member 14 has through drop extrusion 13; The frame 4 that drop is formed below cylinder cap 5 is provided with sample support axle 10, and sample support axle 10 other end stretches out frame 4 and fastening by fastening bolt 12, and sample support axle 10 has slide 8, and sample 9 is placed on slide 8.
On sample support axle 10 of the present utility model, cover has angle indicator 11.
The utility model is provided with droplet counter 6 in frame 4.
Test fluid is contained in fluid tank, when piston rod moves upward, flows through check valve and stop valve enters cylinder barrel (fluid cylinder), and when piston rod moves downward, fluid forms cylinder cap by drop and drips to sample.
Form cylinder cap by changing drop, the internal diameter namely by changing rubber Water outlet changes liquid-drop diameter size.Common diameter is about 1 ~ 3mm.
Utility model works process
(1) sample holder part
Sample support axle is fixed in frame by plain washer, angle indicator and nut by each and every one locating hole of two in frame.
Sample is pasted onto on slide, and slide is fixed by screws on sample support axle.
Unclamp nut, back shaft can Arbitrary Rotation, makes angle indicator localization part concordant with end gap on back shaft, angle when namely reading now droplet impact sample by angle indicator and the angle scale be engraved in frame.
(2) drop forming section
