- the duty cycle of 100% corresponds to a direct coupling the pump motor to the battery.
- a switching element In the control device between a battery connection and a switching element is inserted into a connection for the pump motor be, in particular an electronic switching element, for example a Field effect transistor. This is switched on and off by switching cycles.
- control element a certain duty cycle in the control circuit set, with discretely adjustable positions on the control element for the duty cycle 0% - position "off", battery is completely from Pump motor separated -, approx. 33%, approx. 67% and 100% - direct coupling the battery to the pump motor - are present.
- the electrical power drawn from the battery better matches that in the various Required mechanical power adapted to applications battery life is extended.
- control device is provided with a standard connection with which the Control circuit with a corresponding low voltage connection can be connected to a motor vehicle. This allows the for the operation of the pump required power from a vehicle electrical system be removed.
- the control device can also be used to charge a rechargeable battery Accumulator can be controlled. For example, it can made an adjustment to different large DC voltages become. Furthermore, it is possible to connect one Provide power cord and the switching element with another part train the control circuit as a charger with a rectifier. So an accumulator could be charged at a mains connection.
- Fig. 1 shows a conventional pump 1, for example as a submersible pump is carried out with a pump housing 1.1 and a length-adjustable vertical outlet pipe 1.2. Instead of the outlet pipe 1.2 can also connect other types of cables to a corresponding connection be connected to the pump housing 1.1.
- a pump motor not shown, is arranged, of a supply line 1.3, with an inventive Control device 2 can be connected by the control device 2 Energy is supplied.
- the control device 2 is for better illustration the connections in the opposite position to an operating position shown.
- the control device 2 which is generally made watertight can, in the illustrated embodiment includes an output connection 2.1, which is designed as an electrical connection socket. she is can be connected to the supply line 1.3 via the mating connection 1.4, to power the pump motor. Furthermore are an operating element 2.2 for setting a for an application Power output required, an input port 2.3 for a external power supply to the control device 2, which as a socket for Connection of a charger is executed, and one shown in the Position to the rear can be folded out by approx. 90 ° for hanging the control device is provided on a container wall and a housing 2.5.
- control device is inside the housing 2.5 2 a control circuit designed as a pulse width modulator 2.6 with a switching element 2.7, and a rechargeable battery 2.8 arranged, as shown on corresponding electrical Connections are interconnected.
- the switching element 2.7 is preferably designed as an electronic switching element, for example as a field effect transistor.
- control element 2.2 a certain duty cycle in the control circuit 2.6 set, with which the control circuit 2.6, the switching element 2.7 switches on and off by means of appropriate clock signals.
- the power output setting is to simplify Designations provided a position '0' - duty cycle 0% or pump is switched off -, one position, 1 ' - Duty cycle approx. 33% -, one position, 2 '- Duty cycle approx. 67% - and a position, 3 '- duty cycle 100% or direct connection of the Battery with the pump motor - designate.
- the maximum power output - 100% - is for example for an application the pump is provided as a sprinkler at a high pressure and a large flow is required.
- a medium power output - 67% - is for example for an application of the pump as a sprinkler or provided as a syringe in which a medium pressure and a medium Flow is needed.
- a low power output - 33% - is for example, for an application of the pump for filling watering cans or intended for other water withdrawals where a low pressure at a pump outlet is required.
- the motor input voltage is typically 12 volts in the 1 'to 8 volt position and in the 2' to 10 position Volts reduced.
- the levels are advantageous in ascending order Service sequence arranged. In the illustrated embodiment, this is accessible to the user arranged on the control device housing 2.5
- Control element 2.2 as a rotary switch with fixed locking positions executed, via which the power output for the pump motor can be set in several discrete steps from the battery 2.8.
- a control element can also be used with which the settings are made continuously without discrete levels and thus the power output is also continuously adjustable is.
- the counter-connection arranged at the end of the electrical supply line 1.3 1.4 is preferably designed as a plug, which is not fits into a mains voltage socket.
- the connector can be designed in this way be that it fits on a common 12-volt connection and such for example, can be connected to a vehicle electrical system can, so that the pump without the control device and without own battery can be operated.
- the input port 2.3 to charge the battery 2.8 so that it can be used with also with a charger via a corresponding connection line a vehicle electrical system can be connected. So that's from Motor vehicle electrical system output power with the control circuit 2.6 also adjustable.
- any known 12 volt DC pump can be used be connected to the control device.
- Fig. 3 shows a diagram in which - based on the flow rate - Pressure profiles and efficiency profiles ( ⁇ ) for different ones Control unit settings (motor input voltage is 8 volts, 10 volts, 12 volts) are entered above the flow rate. Along the pressure curve are still values for the battery currents selected measuring points.
- a standard DC motor in this For example, it can be a Mabuchi RS-555SH-4525.
