Energy -saving pretreatment equipment that sprays includes: the end in the input/output of valve is connected to valve, motor, circulating pump, detecting element, analog -to -digital conversion module, main control unit and converter, detecting element to be connected with the main control unit through analog -to -digital conversion module, main control unit, converter, motor and circulating pump connect gradually. The utility model discloses an accommodate motor power is come to the flow or the pressure difference that detect the valve both ends, can be in time the flow of automatic adjustment circulating pump as required, avoided equipment still to keep the high -power to turn round under the low discharge, greatly reduced the consumption of equipment, lengthened the life of equipment.
Description
Technical field
This utility model relates to a kind of energy-saving spray pre-processing device, belongs to surface powder paint coating equipment technical field.
Background technology
Powdery paints is a kind of novel without solvent 100% solid powdery coating, has solvent-free, pollution-free, recyclable, environmental protection, the saving energy and resource, reduces labor intensity and film mechanical strength high. Powder spray is the surface of powder paint to workpiece with powder spraying apparatus, and under electrostatic interaction, powder can be adsorbed in surface of the work uniformly, forms the coating of powdery; Powdery coating solidifies through high-temperature baking levelling, becomes the final coating that effect is different; The spraying effect of powder spray mechanical strength, adhesive force, corrosion-resistant, ageing-resistant etc. in be better than lacquer spraying technique, cost is also under the spraying paint of same effect.
In powder feeder unit, powder is in the state of a kind of fluidisation, and this is realized by compressed-air actuated effect, afterwards powder by siphonage by swiftly flowing air-flow with, formed powder gas mixing, through venturi powder pump, duff pipe, eventually arrive on spray gun. It is transported to the powder on spray gun can regulate and control, specifically can adjust the parameter of powder and air exactly respectively, change the spray pattern of powder outlet quantity and powder, such that it is able to realize different coating thicknesses, meet the needs of different product. For various alloy workpieces, in order to obtain high-quality application product, spray mode generally can be adopted to carry out pre-treatment, spray pre-treatment pump flow is by nozzle flow rate calculation under a certain pressure out, and the general type selecting of pump flow is bigger than normal, common valve on pipeline is utilized to open size to regulate flow and pressure. No matter and this mode uninterrupted is offered to peak power, power consumption is excessive, causes the wasting of resources.
Utility model content

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, this utility model is described further.
Embodiment one
As shown in Figure 1, energy-saving spray pre-processing device includes: valve, motor, circulating pump, detection unit, analog-to-digital conversion module, main control unit and converter, detection unit is connected to the input/output terminal of valve, and is connected with main control unit by analog-to-digital conversion module; Main control unit, converter, motor and circulating pump are sequentially connected with. Described detection unit is pressure transducer, and pressure transducer I is connected to valve output, and pressure transducer II is connected to valve input, is respectively used to the force value of detection valve input/output terminal. Described main control unit is PID controller.
During use, pressure transducer I and pressure transducer II are connected to the valve output on spray pipeline and input, the pressure size at detection valve two ends, the pressure signal recorded transmits to main control unit after analog digital conversion, if valve input pressure is more than outfan, and pressure difference value exceedes certain threshold value, then send signal, by Frequency Converter Control motor reduction, reduce output, make circulating pump hydraulic performance decline, and then make valve input flow and pressure reduce. If valve input pressure sets threshold value less than one, then illustrate that circulating pump output pressure is too small, not up to technological requirement, now send signal, raised speed by Frequency Converter Control motor, improve output, make circulating pump performance boost, and then make valve input flow and pressure raise.
Embodiment two
As in figure 2 it is shown, described detection unit is flow transducer, flow transducer I is connected to valve output, and flow transducer II is connected to valve input, is respectively used to the flow value of detection valve input/output terminal. All the other are with embodiment one.
During use, flow transducer I and flow transducer II are connected to the valve output on spray pipeline and input, the uninterrupted at detection valve two ends, the flow signal recorded transmits to main control unit after analog digital conversion, if valve input flow is more than outfan, and flow difference exceedes certain threshold value, then send signal, by Frequency Converter Control motor reduction, reduce output, make circulating pump hydraulic performance decline, and then make valve input flow and pressure reduce. If valve input flow sets threshold value less than one, then illustrate that circulating pump output flow is too small, not up to technological requirement, now send signal, raised speed by Frequency Converter Control motor, improve output, make circulating pump performance boost, and then make valve input flow and pressure raise.
