The utility model discloses an industry fat liquoring control system has realized can carrying out accurate control to the spraying oil mass of oiling machine to the accurate control of oiling machine atomizing oil mass, and the oil mass too much or the circumstances too little when having avoided the spraying to can guarantee also that the antirust oil on the work piece is even, still simplify the backflow structure among traditional open loop control system simultaneously, very big degree has improved the oil -coated quality of work piece, has improved the finished product qualification rate, has reduced manufacturing cost.
Description
Technical field
This utility model applies the control system of antirust oil to metal works in being related to commercial production.
Background technology
The Main Function of oiler is the surface that antirust oil is coated in the metal works such as strip steel in the industrial production at present, is prevented
Only workpiece gets rusty.Its working method is that the antirust oil in fuel tank is entered inflow pipeline by high-pressure pump, is flowed in dosing pump, meter
Antirust oil is transported to amount pump the high voltage electric field applied in grease chamber, and oil is by high-pressure electrostatic by corona.Corona technology is to improve at present
A kind of important technology of the surface of the work to ink, paint, binding agent and adherent coating, can make the surface tension of spraying oil droplet
Due to the effect disequilibrium of high-pressure electrostatic, then oil droplet is fully atomized.Antirust oil is entered through flow control system again and is applied
The upper and lower knife beam of oil machine, unnecessary oil pass back into fuel tank by oil returning tube.The unnecessary oil sprayed on knife beam is in oiler
Bottom of the frame is collected, stream to oil return fuel tank, then is flow back in fuel tank through scavenge oil pump and filter.This controlling party for applying oil mass
Formula belongs to opened loop control.Antirust oil should be uniformly sprayed in surface of the work, but the problem that oiler is present now is oiling
Amount number be by dosing pump calculate, because of situations such as dosing pump exist gas leakage or sky fuel tank, be easily caused metering
Pump is calculated oil, the situation for actually not having oil, causes belt steel surface not have oiling, causes workpiece to get rusty.Next to that oiling
It is oily uneven that machine is sprayed, and causing workpiece local does not have enough oil, or oil is too much, and these can all cause product quality to ask
Topic, causes business economic to lose.
Utility model content
This utility model provides a kind of industry and applies EFM Electronic Fuel Management, and the spraying oil mass of oiler is precisely controlled,
Oil mass excessive or very few situation when avoiding spraying, and make the antirust oil on workpiece uniform.
Industry of the present utility model applies EFM Electronic Fuel Management, with the fuel tank and input is connected with compression pump respectively
Lower dosing pump and upper dosing pump, are respectively equipped with flow switch, and lower metering in the output pipe of lower dosing pump and upper dosing pump
Pump and upper dosing pump are connected to control unit by converter plant respectively.When upper dosing pump and lower dosing pump receive compression pump
After oil transportation, by the actually detected flow of flow switch, and the detection signal of upper dosing pump and lower dosing pump is respectively transmitted to into control
Unit processed, is compared with value set in advance in control unit, then converter transmission speed is instructed by control unit
The lower dosing pump of control and upper metering revolution speed, accurately supply antirust oil in real time.Wherein flow switch can adopt baffle-type, float
The flow switch type conventional at present such as formula, metallic rotator formula or Spiralism type.Traditional open loop control mode is compared, this practicality is new
Type can realize accurately closed loop control, accurately control to apply the given of oil mass by control unit.Wherein in control unit
Relatively, the program those skilled in the art such as control can be arranged accordingly according to different types of control unit, be not belonging to
Invention section of the present utility model.
In order that the quantity for spray metering to antirust oil is more accurate, described flow switch is respectively arranged on into lower metering preferably
The output pipe of pump and upper dosing pump can so be evaded because of the oil mass in the output pipe near by one end of oiling workpiece
Error between the quantity for spray that causes of the reason such as loss and output, can more accurately detect actual spraying oil mass,
The rotating speed of corresponding measurement pump is controlled on this basis.
Further, control unit be also associated with show operation terminal, such as PC computers, panel computer, handheld terminal etc.,
It is by showing output and spraying state that antirust oil is can show that in operation terminal, convenient manually to be adjusted in real time
It is whole.
Optionally, described control unit is PLC (programmable logic controller (PLC)) devices, or single-chip microcomputer, service
The equipment with data-handling capacity such as device, those skilled in the art can carry out corresponding program setting according to physical device, and
Specific procedure content is not belonging to the present utility model content.
In order to simplify structure, lower dosing pump and upper dosing pump can be connected to the different ends of same converter plant
Mouthful, the signal of lower dosing pump and upper dosing pump is respectively transmitted to carry out in control unit point by the different port of converter plant
Analysis.
On this basis, oil level sensing device is additionally provided with fuel tank, for monitoring the high and low position of oil level.
Further, immersion heater is additionally provided with fuel tank, for antirust oil is heated to 45～60 degree, to reduce preventing
Rust oil viscosity.
Industry of the present utility model applies EFM Electronic Fuel Management, realizes the precise control that oil mass is atomized to oiler, can be right
The spraying oil mass of oiler is precisely controlled, it is to avoid oil mass excessive or very few situation during spraying, and also be ensure that
Antirust oil on workpiece is uniform, while also simplify the return-flow structure in conventional open-loop control system, high degree improves work
The quality of part oiling, improves product qualified rate, reduces production cost.
Specific embodiment with reference to embodiments, remakes to the above of the present utility model further specifically
It is bright.But this scope for being interpreted as the above-mentioned theme of this utility model should not be only limitted to Examples below.New without departing from this practicality
In the case of the above-mentioned technological thought of type, the various replacements made according to ordinary skill knowledge and customary means or change,
Should be included in the range of this utility model.
