Description
Technical field
The utility model relates to a kind of energy-conservation constant oil supply pressure system, belongs to industrial fuel oil and supplies with the feedway class.
Background technique
The industrial fuel oil combustion system needs the fuel oil supply device of pressure stability, generally used the diesel oil gear pump to add that scavenger valve regulates oil pressure in the past, because the rotating speed of gear pump is relevant with electrical network power frequency and voltage, with fuel transfer pressure and irrelevant with oil mass, the result is in mains frequency and voltage change, when burner changes with oil mass, can cause pressure fluctuation, when especially several oven or many burners are worked simultaneously, its changes in flow rate is particularly evident, fuel feed instability when the result can cause burning, cause burning phenomenon such as insufficient to produce, for addressing this problem, when many oil inflame equipment shared overlap oil supply system, improve fuel feeding pressure (0.5Mpa) often earlier at present, the expensive decompression stable-pressure device of one cover is installed on every oil inflame equipment again, and on every stove the setting pressure detecting switch.Also have a problem: the burning capacity when the maximum combustion amount is gone up in the general design of combustion heating furnace all than insulation is big three times, so, oil supply system must satisfy the add up demand of maximum combustion amount of all devices, what the power of oil supply system oil pump just selected as a result is bigger, and the own energy consumption during like this with constant power operation is also bigger.
But, for many years the oil fired furnace technology is understood according to the inventor, in actual use, fuel quantity is relevant with the operating modes such as temperature of stove, this is a variable at random, obviously the oil supply system of this constant power of use had not both met the actual user mode of fuel oil industrial furnace, was a kind of waste to the energy of growing tension yet.
Therefore, exploring or propose a kind of more scientific and reasonable energy-conservation, constant oil supply pressure system has been the expectation that the fuel oil road produces practical producer.
The model utility content
Send out the purpose of the present utility model: be intended to propose a kind of new, have an oil supply system energy-conservation, the constant voltage function.
Foregoing invention has following technological scheme to realize:
This energy-conservation constant oil supply pressure system, oil tank 1, valve 2, filter 3, oil pump 4, automatic switch-over circuit 5, frequency variator 6,7, signal processing module 8, pressure transmitter 9, fuel-pressure switch 10 and pressure gauge, connecting tube etc. by the band relief opening are formed, it is characterized in that: the pipeline of all devices all is connected on the oil supply system house steward 15, to be divided into two-way from the oil pipe that oil tank 1 comes out, form each forms shape in parallel by a filter 3, oil pump 4 and valve 1 and in the centre two of UNICOM branch oil circuits again, the while all is equipped with valve 2 at oil pump 4 and filter 3 front and back; On total transport pipe of oil pump outlet, fuel-pressure switch 10, pressure gauge 11 and pressure transmitter 9 are installed; A frequency variator 6 and frequency variator 7 on the output pipe of two oil pumps, have been prepared simultaneously separately.
The return tube of a band throttle valve (14) also is housed in total transport pipe outlet in addition.
The energy-conservation constant oil supply pressure system of this kind according to above technological scheme proposition, pressure transmitter converts the fuel oil delivery pressure to electrical signal, send into the frequency control terminal of two frequency variators respectively, by setting to frequency variator, can be so that the oil pressure of oil transportation house steward output terminal maintains within the convenient pressure scope, by evidence, use this constant pressure frequency conversion oil supply system, can save electric energy 40%, can realize low pressure oil transportation (0.1Mpa), when flow changes significantly oil pressure stability is in ± 0.01Mpa, save decompression stable-pressure device and the pressure-detecting device installed on every stove, and combustion stability is improved.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure 1, oil tank 2, ball valve 3, filter 4, gasoline pump 5, automatic switch-over circuit 6, frequency variator 7 commonly used, standby variable frequency device 8, signal processing module 9, pressure inverting instrument 10, fuel-pressure switch 11, pressure gauge 12, ball valve 13, exhaust valve 14, throttle valve 15, oil supply system house steward
Embodiment
This energy-conservation constant oil supply pressure system as shown in the figure, it is a kind of improvement to original congenerous oil supply system.Oil supply system after this improvement, oil tank 1, valve 2, filter 3, oil pump 4, automatic switch-over circuit 5, frequency variator 6,7, signal processing module 8, pressure transmitter 9, fuel-pressure switch 10 and pressure gauge, connecting tube etc. by the band relief opening are formed, it is characterized in that: the pipeline of all devices all is connected on the oil supply system house steward 15, to be divided into two-way from the oil pipe that oil tank 1 comes out, form each forms shape in parallel by a filter 3, oil pump 4 and valve 1 and in the centre two of UNICOM branch oil circuits again, the while all is equipped with valve 2 at oil pump 4 and filter 3 front and back; On total transport pipe of oil pump outlet, fuel-pressure switch 10, pressure gauge 11 and pressure transmitter 9 are installed; A frequency variator 6 and frequency variator 7 on the output pipe of two oil pumps, have been prepared simultaneously separately.
Its working principle and effect are as follows:
Because the pipeline of all devices all is connected on the oil supply system house steward; the oil pipe that comes out from oil tank is divided into two-way; twin filter, two oil pump (is equipped with a usefulness); and valve is housed all before and after oil pump and filter; can not shut down filter rinsed and oil pump; on total transport pipe of oil pump outlet, pressure switch, pressure gauge and pressure transmitter are installed; pressure switch can be sent alarm signal when the pressure superelevation; and close the working power of oil transfer pump frequency variator commonly used automatically; enable emergency bearing oil pump this moment, allows emergency bearing oil pump start automatically and take over job.Pressure gauge is used to indicate pressure value, pressure transmitter converts the fuel oil delivery pressure to electrical signal, send into the frequency control terminal of two frequency variators respectively, by setting to frequency variator, can be so that the oil pressure of oil transportation house steward output terminal maintain within the convenient pressure scope, when flow occurring in many oil-using units work and change significantly, frequency variator is according to the variation in pressure of oil transportation house steward output terminal, automatically adjust the rotating speed of oil pump, both guaranteed the stable of oil pressure, saved electric energy again.Export the return tube that a band throttle valve also is housed at total transport pipe, all devices stops with behind the oil under emergency case, just in case cause the oil pressure superelevation, then can pass through the return tube release pressure.
By evidence, use this constant pressure frequency conversion oil supply system, can save electric energy 40%, can realize low pressure oil transportation (0.1Mpa), oil pressure stability was in ± 0.01Mpa when flow changed significantly, save decompression stable-pressure device and the pressure-detecting device installed on every stove, combustion stability is improved.
