Censtar 3100 display board pressure test was carried on.2, line corner should be fuel dispenser electronic board as little as possible, tankers and underground tank horizontal distance should not be commonly more than 30 meters, the lowest surface and oil tank tankers oil inlet of the vertical distance should be not more than 6 meters, lest affect suction.

The fuel dispenser electronic board oil pipeline between the mouth and the machine suction tubing triangle flange with oil seal.3, within the tank into the bottom of the tubing check valve should be installed 1.5 inch (two-door bottom valve), the lower check valve is apart from the tank bottom 10 cm, cleaning tank carefully before install the check valve and check valve in sundry, 3100 display board one-way valve sealing performance and oil testing, lest machine enabled one-way valve block and leak happens.

In order to prevent the crosstalk between wire PCB circuit boards, we should be avoided when designing wiring the equality of long-distance line, the distance between the lines to open and as far as possible, signal wire and ground wire and the power cord as far as possible, don't cross.In some very sensitive to interference signal lines between a grounded printing line, 3100 main board can effectively restrain crosstalk.

Censtar circuit board according to the layer to points, divided into the single panel, double panel and multilayer circuit board of three big categories.
First is single panel, on the most basic of PCB, parts on one side, conductor is focused on the other side. Because wires only appear on one side, so I said this kind of PCB is called single sided PCB.Single panel circuit board is usually simple, low cost, but the downside cannot be applied to complex products.
Is an extension of the 3100 main board single panel, double panel when single wiring cannot satisfy the need of electronic products, 3100 main board is about to use double panel. Both sides have copper clad wire, and 3100 main board can through the hole to turn-on, the line between the two layers of the network connection required circuit board.
Sandwich plate is a three layer above the conductive graphics and insulation materials to be apart in laminated, and meantime conductive graphics interconnect PCB as required. Multilayer circuit board is electronic information technology to high speed, multi-functional, large capacity, small volume, thin, lightweight, a product of the direction.

Keypad display board of fuel dispenser

(5 digit)(11*11*4;NW:65g)

Board circuit electronicto replace measuring microprocessors, through background gas station modification parameters, such as increasing the number of pulse encoder sends, the purpose of these methods is to steal oil.When measuring personnel to the gas station inspection, they need only carried out on the tanker off electricity to a remote control of electrical operation or keypad display board handlers (or background) controller, tanker returned to normal immediately, keypad display board make the measurement personnel do not know how to start.

Censtar board circuit electronic metrological administrative department of the government, it is difficult to investigate.For gas stations to steal oil broad topics in society, from 2001 to 2006, the central television station gas station entrap consumer focus interview program many times reported, metrological administrative department of the government a lot of pressure.General administration of quality supervision, inspection and quarantine the metrological department technical institutions research as soon as possible by technical means contain oil theft behavior of gas station.

3100 power board

(10*12*8;NW:300g)

Tankers exports increased year by year in our country in recent years, some of the tanker aircraft manufacturer specializes fuel dispenser display board in the international market, products with its high quality, low price welcome in developing countries, is developing gradually from developing countries to developed countries. Believe in the near future our tankers power board to reach the international advanced level, and will occupy the international market.

Flow detection circuit is fuel dispenser display board shown in figure 1.Light code disc measurement device for the flow sensor, the casing channel switch fixed to the controller, spins disc (slotted) via flexible shaft directly with the gauge on the tanker shaft connection again.When refueling tanker, rotating disk by meter shaft drives the rotation, triode BG1 output pulse sequence, the hair oil on the number of liters proportionally converted to pulse count, after this, the 74 ls14 schmidt circuit, pulse shaping into single chip microcomputer internal counter, can be measured by 3100 power board counting value amount.

Electronic totalizer board

(7*8*2;NW40g)

Censtar electronic totalizer board when quantitatively refueling, first press the quantitative/random refueling selection switch, the system is in standby mode.Through the keyboard input amount, and then the machine automatically converts the hair amount circuit boards under pulse quantity timer/counter T0, to counter the T1 please zero at the same time.At this point, when the oil gun down from the rack, photoelectric switch conduction.

Circuit boards boot internal signal is sent to the CPU.Drive circuit with explosion-proof contactor to start the motor start hair oil, motor drives the pump from the tank in oil and gas absorption into the filtration apparatus, pure oil flowing into the flow meter and moves the pistons, electronic totalizer board synchronous drive as photoelectric coding dish of flow sensor, produce a series of pulse signals sent to the CPU counter to count, CPU count value read from the counter T1 and after processing.

Driver Board of fuel dispenser

Fuel dispenser driver board explosion-proof contactor to start the motor start hair oil, motor drives the pump from the tank in oil and gas absorption into the filtration apparatus, pure oil driver board flowing into the flow meter and moves the pistons, synchronous drive as photoelectric coding dish of flow sensor, produce a series of pulse signals sent to the CPU counter to count, CPU count value read from the counter T1 and after processing.

Fuel dispenser driver board display synchronously displays the current actual amount hair oil.When overflow T0 count, that is, when sending the preset amount of hair oil, hair the interrupt signal and closed by a contactor motor, the CPU according to T1 count after processing according driver board to the actual amount of hair oil, hair oil.Here is the purpose of using a T1 prevent impulse, make the both sides do not suffer, and simplify the display part programming.

6300 communication board of fuel pump

Motor start-stop control fuel dispenser communication board is mainly the choice of intermediate driving element, thyristor trigger the RMB and the exchange of solid state relay is widely used.This system adopts the AC solid state relays (AC - SSR) as a power drive components.As a kind of non-contact electronic switch components, using photoelectric isolation between its input and output, no electricity contact each other, which can realize non-contact no spark, connect 6300 communication board and disconnect the motor input only requires the drive current of the small.

Fuel dispenser communication board is suitable for gas station the occasion of this sample request for fire and explosion prevention.Due to the perceptual load, lost out at its termination zno varistor RT to protect it.When P2. 6 entered a "1", the triode conduction, AC - SSR on explosion-proof contactor, electric machine electricity work, 6300 communication board began to come on;Conversely, AC - SSR shut off, the motor stopped electricity, stop for gas
