Definitions
- the invention relates to a metering system for metering a liquid.
- Downstream SCR catalyst up to 80% of nitrogen oxides in harmless nitrogen and in water to.
- urea solution is a chemically aggressive and very fluid medium that tends to crystallize
- special pumps are used to promote it, in which the urea solution does not come into contact with the drive units of the metering pump.
- the pumping room is z. B. separated by a membrane or other flexible part.
- the pump runs continuously and builds a pressure of z. B. 5 bar.
- the urea In the pipes and systems is the urea. If, after the vehicle is parked, the ambient temperature falls below freezing, the system will freeze completely. Since not all components can withstand freezing, the urea solution must be pumped back into a reservoir after the vehicle has been parked. In known systems, this is done by means of a 4/2-way valve, which reverses the conveying direction.
- this object is achieved by the subject matter of claim 1. It thus succeeds to provide a dosing system which has a very compact structure, and which sucks in one direction of rotation of the electric motor, the liquid to be dosed from the reservoir and the consumer transported, and in the other Direction of rotation sucks this liquid from the lines of the system and transported back to the reservoir.
- Fig. 1 is a perspective view of an embodiment of a metering system 30, which serves in this example for the metering of urea, wherein the
- Direction of conveying by the direction of rotation of a multiphase brushless external rotor motor 32 and the flow rate per second is determined by the speed of this electric motor 32, which allows a very sensitive and economical setting of the desired dose
- FIG. 2 is a plan view from above of the dosing system of FIG. 1, seen in the direction of the arrow II of FIG. 1,
- Fig. 3 is a longitudinal section through the metering system 30, viewed along the line III-III of
- FIG. 2 4 is a plan view showing the metering system of FIG. 3 from the right, viewed along the line IV-IV of FIG. 2,
- FIG. 5 is a plan view, taken along the line V-V of Fig. 2,
- Fig. 6 is an enlarged section, taken along the line Vl-Vl of Fig. 5; this section applies to the rotor position of FIG. 5 and looks different in other rotor positions,
- Fig. 7 is an enlarged section, taken along the line VII-VII of Fig. 5; as well as the section of FIG. 6, this section for the rotor position, which is shown in Fig. 5,
- FIG. 8 is an enlarged sectional view taken along the line VIII-VIII of FIG. 5; FIG. as well as the sections according to FIGS. 6 and 7, this section applies to the rotor position of FIG. 5,
- Fig. 9 is an enlarged section, taken along the line IX-IX of Fig. 5; as well as the sections of FIGS. 6, 7 and 8, this section applies to the rotor position of Fig. 5, and
- Fig. 1 shows a three-dimensional representation of a preferred embodiment of a dosing system 30, as e.g. is used to inject a urea solution as needed in the exhaust stream of a diesel engine.
- the dosing system has a multiphase brushless motor to drive it
- External rotor motor 32 whose speed behavior can be controlled by means of a PWM control signal, as the e.g. is known from EP 1 41 3 045 B1.
- the dosing system 30 allows the speed and direction of rotation of the motor to be controlled according to the speed and power requirements of the vehicle on which the metering system 30 is located located.
- the elements for this are determined by the manufacturer of the engine control according to the needs of the respective vehicle and can vary greatly depending on the type of vehicle (car, truck, airplane, helicopter, ship, etc.). It is a merit of the present invention that the dosing system 30 for very different
- the motor 32 has drive electronics, e.g. a three-phase inverter. This electronics is in turn controlled by an arrangement that serves to
- Duty cycle pwm of a PWM signal which is supplied via a line to decode and thereby control the engine in terms of direction and speed. If the duty cycle is referred to as pwm, the following assignments result as a non-binding example: pwm operating state
- Fig. 1 shows an example of a simple mechanical construction of a dosing system 30, which is naturally suitable for a variety of applications, e.g. also in the
- the system 30 here has a base 40 on which a first support 42 is arranged on the right, which carries a bearing element 44, which is shown here as a ball bearing. At a distance from the carrier 42, a second carrier 46 is arranged, which carries a bearing element 48 as shown in FIG. 3, which is also shown as a ball bearing.
- the bearing elements 44, 48 are arranged so that they are aligned with each other.
- a shaft 50 is mounted, on which between the bearing elements 44, 48 an eccentric bushing 52 is attached, which also serves as a spacer between the bearing elements 44, 48.
- the bush 52 serves to drive a pump 53, which is thus arranged between the bearing supports 42 and 46.
- the inner ring 54 of an eccentric bearing 56 is fixed, the outer ring 58 is fixed on the inside of a ring 60 which serves as a support for a pumping ring 62.
- the pumping ring 62 is made of a suitable synthetic rubber (elastomer) and is fixed by plastic spraying in an annular groove 64 of the ring 60 so that it follows the movements of the ring 60.
- This can e.g. be made of steel, nickel or bronze.
- PEDM polyethylene-diene monomer
- the pumping ring 62 is surrounded on its outer side by a stationary ring 70, which is connected by means of screws 84 with the base 40 and has a T-shaped cross section, namely one, to the axis of rotation 74 of FIG .. the dosing system parallel edge portion 76, and a perpendicular to the axis of rotation 74 extending holding portion 78, whose radially inner edge is designated 80. / ⁇
- the stationary ring 70 is widened in its lower region and connected to the base part 40 by means of two screws 84.
- the stationary ring 70 is thus in the assembled state between the carriers 42, 46, ie the bearings 44, 48 are arranged close to each other and can therefore serve as a bearing for the entire metering system 30. - -
- a support tube 90 is provided, through which the shaft 50 extends, see. Fig. 3.
- the shaft 50 is thus supported only by the bearings 44 and 48.
- end of the cup-shaped magnetic yoke 92 of the rotor 94 of the motor 32 is fixed.
- On the inside of the yoke 92 is a magnetic ring 96, which is separated by an air gap 98 from the inner stator 100 of the motor 32.
- the inner stator 100 is mounted on the outside of the support tube 90.
- the motor 32 also has a printed circuit board 102 on which electronic components of the motor 32 are located.
- the printed circuit board 102 is connected to a plug 106 via a cable 104.
- the motor 32 is powered by the cable 104, usually with DC from a battery, and in the cable 104 is also a
- Control line are controlled by the speed and direction of rotation of the motor 32.
- a great advantage of a brushless motor, especially on a vehicle, is the high efficiency that can be achieved with such an arrangement.
- the motor 32 drives via the shaft 50 to the eccentric bushing 52, and this puts the eccentric 54 in an eccentric movement, so that the ring 60 is also placed in this eccentric movement.
- two ports 122, 124 are provided at a suitable location, which are connected to the local portions of the pumping chamber 120, cf. Fig. 5. -
- a wedge 140 which has two functions: a) He spreads the pump ring 62 in the radial direction, so that this with his
- the pump ring 62 has lateral extensions or flanges 142, 144, which extend along the flanks 146, 148 of the holding part 78 and are pressed by pressing plates 51 1, 52 against these flanks, so that the pumping chamber 120 held (fixed) and sealed against the holding part 78, cf. FIG. 8.
- the holding section 78 has in each case a bead-like broadening 145, 145 ', which further improves the seal there.
- the pressure plates 1 6, 148 are pressed by screws 150, one of which is shown in Fig. 6, in the direction against each other.
- the pumping chamber 120 which in one embodiment has a maximum height of less than one millimeter, is thus connected to the outside world only via the ports 122, 124 and is otherwise hermetically sealed.
- Figs. 10A to 10J serve to explain the operation.
- the reference numerals are the same as in Figs. 1-9. However, the ring 60 to which the pump ring 62 is attached is not shown separately.
- a position indicator 170 is shown in each figure, indicating the position of the maximum of the eccentric bushing 52 in a clockwise rotation, as follows:
- the pumping ring 62 By means of the eccentric bearing 56, therefore, the pumping ring 62, continuously advancing in the circumferential direction, successively at the points (for example) 12 o'clock (FIG. 10A), 1 o'clock 30 (FIG. 10B), 3 o'clock (FIG pressed together strongly that there the pumping chamber 120 is no longer permeable and thus the fluid in the pumping chamber 120 in
- Suction port, and the port 1 24 to the pressure port which is not shown, since it simply corresponds to a mirror of FIGS. 10A to 10J.
- the metering system 30 described is very easy to maintain because the pump 53 can be easily replaced. - Naturally, many modifications and modifications are possible within the scope of the present invention.
