The structural representation of the device of the hydraulic support surface high pressure airless spraying that Fig. 1 provides for the utility model embodiment.
Among the figure: 1, stock chest, 2, booster pump, 3, pressurized cylinder, 4, pressure sensor, 5, movable board, 6, the board pushing hands, 51, universal wheel, 31, hydraulic means, 32, high-pressure outlet.
The specific embodiment
To combine accompanying drawing that the utility model embodiment is done to describe in detail further below.
The device of the hydraulic support surface high pressure airless spraying of the utility model, its preferable specific embodiment is:
Comprise stock chest, booster pump, pressurized cylinder, movable board; The import of said booster pump is connected with said stock chest; The import of said booster pump is connected with the import of said pressurized cylinder lower end; Be provided with pressure sensor between said booster pump and the pressurized cylinder, said pressure sensor is electrically connected with the control module of said booster pump;
The upper end of said pressurized cylinder is provided with hydraulic means, and the middle part is provided with high-pressure outlet;
The bottom of said movable board is provided with travelling wheel, and an end of movable board is provided with the board pushing hands, and the travelling wheel of this end is a universal wheel.
When the pressure of the paint between said booster pump and the pressurized cylinder during less than setting value, booster pump starts; When the pressure of the paint between said booster pump and the pressurized cylinder during more than or equal to setting value, booster pump cuts out.
Adopt the device of above-mentioned hydraulic support surface high pressure airless spraying that application is carried out on the hydraulic support surface.Application pressure is 6-30MPa.
The structural member of hydraulic support is box-structure (cylinder, sphere etc. that are different from plate or rule), and a lot of places are difficult spraying such as turning, narrow shelves, groove positions, and requirement has enough pressure and just can spray to.Being sprayed in the pressure 6-30MPa of the utility model chosen; Mainly see the viscosity (i.e. the flowability of paint, the ability of atomizing) of paint; And viscosity is a uncertain parameter by the factor affecting such as diameter that receive its chemical composition, environment temperature, nozzle, only on-the-spot adjustment when spraying.Certainly pressure is high more, and effect is good more, but can bring that energy consumption is big, noise big, can shorten equipment life, has the potential safety hazard of high pressure simultaneously.
The utility model adopts supercharging device that coating is increased to high pressure (6-30MPa); Through very thin spray orifice ejection, it is fan-shaped vaporific that coating is formed, and can spray thicker coating; Because entrained air not in the coating; And higher coating transmission efficiency and production efficiency, thereby form fine and close coating in the metal surface, make the airless spraying surface quality significantly be superior to aerial spraying.
Airless spraying has the following advantages:
High coating efficiency, spray efficiency is up to 500-1200m per hour
2, be more than 10 times of conventional rollers construction, be more than 3 times of air compressor spraying;
