Description
Technical field
The utility model relates to a kind of heating type fuel tank fuel sucking pipe that is used for the diesel locomotive fuel oil supply system.
Background technique
Prior fuel oil case fuel sucking pipe, employing be not heat fuel sucking pipe, fuel oil waxization and ice knot can not ensure the unimpeded supply of fuel oil under low temperature environment.Part heating type fuel tank fuel sucking pipe; Its fuel sucking pipe and return tube are and set up single-column type separately; Both caused the increase of fuel tank mounting hole site; Again because of dividing if between return tube outlet and the fuel sucking pipe inlet distance elongate, to making the oil return that has heat energy can not effectively import fuel sucking pipe, and make increase heating time bring electric energy loss.Because of the full oil condition of fuel tank is few, fuel sucking pipe all is that total length heats with power, and inlet port is being blocked up by the ice slag of waxization, and fuel delivery is not smooth.Do not have filter, make the oil circuit easy blocking.
Summary of the invention
In order effectively to utilize oil return heat energy fast; Around the inlet port of heating fuel sucking pipe reaches; Reduce power consumption, realize under low temperature (40 ℃) environment, use high grade (0#) fuel oil energy is separated cured fast and is thawed; Guarantee unimpeded supply of oil circuit and primary filter, the utility model proposes a kind of heating type fuel tank fuel sucking pipe.
For realizing above-mentioned purpose, the utility model adopts following technical proposals:
A kind of heating type fuel tank fuel sucking pipe comprises flange seat, fuel sucking pipe, return tube and electric heating apparatus, and fuel sucking pipe and return tube are installed on the flange seat side by side; The upper end of fuel sucking pipe and return tube is communicated with fuel-displaced connecting bolt and oil return connecting bolt respectively; The lower end of said fuel sucking pipe is equipped with filter, and said electric heating apparatus places in the fuel sucking pipe, and also is looped around in the filter; This electric heating apparatus one end is fixed in the tube wall of fuel sucking pipe oiler through rivet, and the other end is connected with the positive source line.
Upper half part that said heater is positioned at fuel sucking pipe is straight, lower half portion shape in the shape of a spiral.
Said flange seat lower end is provided with fuel sucking pipe side by side and return tube is installed tapped hole, and fuel sucking pipe and return tube are fixed on the lower end of flange seat through screw thread and sealer sealing.
Said fuel sucking pipe and return tube vertical axial are respectively equipped with fuel-displaced connection screw thread hole and oil return connection screw thread hole; Fuel-displaced connection screw thread hole and fuel sucking pipe connect; Oil return connection screw thread hole and return tube connect; Said fuel-displaced connecting bolt and oil return connecting bolt respectively with go out, the oil return tapped hole is tightly connected, fuel-displaced connecting bolt is corresponding with the transport pipe and the return tube of motor respectively with the oil return connecting bolt simultaneously.
Fuel sucking pipe at flange seat is axially arranged with the power supply introducing tapped hole that connects with fuel sucking pipe; Stretch out this power supply introducing tapped hole on the said positive source alignment and link to each other with the cathode power supply splicing ear, the positive source line is introduced tapped hole envelope means of press seals through cover sealing plug and envelope pressure bolt and power supply.
The utility model is confirmed the length of fuel sucking pipe and return tube according to the height of fuel tank, confirms heater power according to fuel sucking pipe length, when guaranteeing that fuel sucking pipe is uneven in length, and the conformity of heating function.The positive source splicing ear is connected with vehicle power, and negative pole constitutes the loop through the coupled negative pole conducting that connects part of flange seat.If the heating Out let of power input terminal and Integrated electromagnetic pump is pegged graft, can receive the unified control of temperature control system of Integrated electromagnetic pump, realize opening and closing automatically of heating and compensation heating.Formed the integral body heating oil circuit of a conducting from the fuel sucking pipe oiler to oil out port, because this design proposal is set up in parallel fuel sucking pipe and return tube, heating power concentrates on around fuel sucking pipe lower half portion and the filter; When fuel oil waxization is tied with ice; At first energising heating fuel sucking pipe starts locomotive, and the oil return that operation process will have heat energy again imports around the fuel sucking pipe, has made full use of effective application of the gentle electric energy of oil return thermal compensation oil; Reduce heating time, reduce power consumption.Thereby constituted whole rapid heating oil circuit and primary filter, guaranteed the unimpeded supply of oil circuit.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Like Fig. 1, Fig. 2, (wherein Fig. 2 is Fig. 3 A-A sectional view) shown in Figure 3; A kind of heating type fuel oil of the utility model fuel sucking pipe presses bolt 8, negative pole rivet 9, fuel-displaced connecting bolt 10, oil return connecting bolt 11 and cathode power supply splicing ear 12 to constitute by flange seat 1, fuel sucking pipe 2, return tube 3, filter 4, electric heating apparatus 5, positive source line 6, sealing plug 7, envelope.Flange seat 1 lower end is provided with fuel sucking pipe 2 side by side and with return tube 3 tapped hole is installed; Fuel sucking pipe 2 installs and fixes through screw thread and sealer sealing with return tube 3; Fuel sucking pipe lower end mounting filtering device 4; Fuel sucking pipe 2 sets out respectively with return tube 3 vertical axials, the oil return connection screw thread hole, and fuel-displaced tapped hole and fuel sucking pipe 2 connect, and oil return tapped hole and return tube 3 connect; Fuel-displaced connecting bolt 10 and oil return connecting bolt 11 respectively with go out, the oil return tapped hole is tightly connected with compound gasket, the transport pipe that is connected to motor is connected with return tube is corresponding with it; Axially establish electric heating apparatus 5 power supplys at the fuel sucking pipe of flange seat 1 and introduce tapped hole; Connect with fuel sucking pipe 2, electric heating apparatus 5 overcoat heatproofs, oil resistant, spaghetti place in fuel sucking pipe 2, the filter 4, and upper half part is straight in the fuel sucking pipe 2; Lower half portion is a helical; In the filter 4 also around electric heating apparatus 4 arranged, electric heating apparatus 4 one ends are fixed in the tube wall of fuel sucking pipe 2 oilers through negative pole rivet 9, an end is connected with positive source line 6.Positive source line 6 outer ends cover sealing plug 7 presses bolt 8 and its power supply to introduce tapped hole lock means of press seals through envelope, and positive source line 6 the other ends connect cathode power supply splicing ear 12.The utility model is confirmed fuel sucking pipe, return tube length according to the height of fuel tank, confirms heater power according to fuel sucking pipe length, when guaranteeing that fuel sucking pipe is uneven in length, and the conformity of heating function.The positive source splicing ear is connected with vehicle power, and negative pole constitutes the loop through the coupled negative pole conducting that connects part of flange seat.Formed the integral body heating oil circuit of a conducting from the fuel sucking pipe oiler to oil out port, because this design proposal is set up in parallel fuel sucking pipe and return tube, heating power concentrates on around fuel sucking pipe lower half portion and the filter; When fuel oil waxization is tied with ice; At first energising heating fuel sucking pipe starts locomotive, and the oil return that operation process will have heat energy again imports the fuel sucking pipe oiler, has made full use of oil return thermal compensation oil temperature; Reduce heating time, reduce power consumption.Thereby whole rapid heating oil circuit and primary filter have been constituted.
