Definitions

  • the invention relates to a double pump with two impellers arranged in a housing, which convey a conveying medium, each impeller being driven by an electric motor, and by means of a higher-level control and / or regulation, the speeds of the two electric motors each independently of one another between the motor standstill and the nominal speed can be set or regulated.
  • double pumps are preferred today.
  • Two impellers are arranged in one housing, each impeller being driven by an electric motor.
  • the electric motors usually have 3-4 speed levels that can be set by means of a control. If the flow rate changes, different delivery levels result.
  • Pump systems are also known in which a delivery head can be predetermined and a regulation by switching over to the individual speed stages ensures the delivery head in a certain range. However, relative pressure fluctuations disadvantageously occur here.
  • individual pumps are known, in which the speed by means of a Regulation is continuously changeable.
  • the electronics of the control can usually be connected to a pump control computer via a digital interface.
  • the master computer specifies the required speeds for the motors.
  • the pump control computer can also specify which electric motor should drive the respective pump at what speed at a specific time. In multi-pump systems, for example, a load-dependent connection and disconnection of another pump can be carried out if the setpoint deviates.
  • a double pump which has a superordinate pump control for a double pump.
  • the speed of both motors of the double pump is regulated continuously, ie without speed jumps according to need
  • the higher-level control system is fastened together with other switching devices centrally on a wall in the room.
  • the object of the invention is therefore to provide a double pump which avoids the disadvantages of the prior art listed above, as a result of which the double pump is easier, cheaper and faster to install.
  • This object is achieved in that the higher-level control and / or regulation is arranged directly on one of the two electric motors. This eliminates the otherwise necessary cables or transmission facilities for the Control data, which not only reduces installation costs, but also the space required for the pump and control.
  • each of the two electric motors has a control, the respective control regulating the motor speed of the associated electric motor in accordance with the command variable specified by the higher-level control and / or regulation, and the controls being designed as modules, each based on the associated one Electric motor are in particular releasably attachable and are in electrical connection with the respective electric motor by means of electrical contacts.
  • the controls are arranged in a housing. This housing is in particular releasably attachable to one of the electric motors and is in electrical connection with the two electric motors by means of electrical contacts. This eliminates the need for a housing, which in turn reduces production costs.
  • the speed of the second pump can be increased continuously from standstill to the required speed, thereby avoiding pressure jumps.
  • the command variable is advantageously the delivery head or pressure difference between the suction and outlet side of the respective pump.
  • the pressure difference can be determined using a conventional pressure meter.
  • each electric motor is preferably determined by the respective associated control, the actual delivery head or pressure difference between the intake and outlet side of the respective pump being able to be determined from the pump and motor characteristic curve from the current consumption of the motor, and the pressure difference determined being the actual value for the respective regulation.
  • the control values can be given different reference values, which means that any delivery head or pressure difference can be adjusted.
  • the pump is advantageously operated in double operation, with the higher-level control unit switching on both pumps at the same time in order to achieve a desired delivery head, and both controls specifying the same values for the reference variable, in such a way that both pumps deliver at the same speed.
  • Both pumps advantageously have the same pump characteristics, which means that both pumps run at the same speed in the same operating points. As a result, both pumps are operated with the same operating times, which means that both pumps can wear evenly.
  • the maintenance interval is then the same for both pumps, whereby maintenance can be carried out for both pumps at the same time.
  • both pumps deliver at the same speed, the speeds of the two pumps are lower than the speed of a single pump with the same delivery head to be provided.
  • the pump running noises are significantly lower.
  • the pump runs quieter and quieter.
  • Another advantage of this method is that no switching or switching is necessary, which advantageously avoids pressure and volume flow jumps.
  • the controls are modules, each of which can in particular be releasably attached to the associated electric motor and are in electrical connection with the electric motor by means of electrical contacts. It is also advantageous if the controls are arranged in a housing and the housing is in particular releasably attached as a module to an electric motor.
  • the higher-level control system should also be designed as a module, the module should in particular be releasably attachable to a control module.
  • the control module is in electrical connection with the control module by means of electrical contacts. It is also advantageous if the higher-level control system is arranged in a housing together with the two controls and the housing can be detachably attached as a module to an electric motor.
  • the higher-level control is arranged in a housing together with only one regulation of an electric motor, the housing as a module on this electric motor being particularly releasably attachable and the control of the other electric motor as a module on the other electric motor being releasably attachable is.
  • Such a modular design allows various user-specific controls and / or regulations to be easily and quickly attached to the double pump, which means that additional cables are unnecessary and high operational reliability of the pump can be achieved.
  • the higher-level control system can advantageously be connected to a pump control computer by means of data and / or control lines or to one or more other higher-level control systems or controls of single or double pumps. This has the advantage that several double pumps can be controlled by means of a higher-level controller.
  • the higher-level controller can also be programmable. It can also have a programmable timer, by means of which the pumps can be switched on or off at predefinable time intervals, or their speeds or the level of the delivery head can be preset.
  • the higher-level control system can switch on the pumps alternately in chronological order, such that, apart from the switch-on phase, only one pump ever conveys the pumped medium. In this way, it can advantageously be achieved that both pumps are operated with the same operating times, so that the maintenance intervals for the pumps can be set the same.
  • the higher-level control system can also increase the speed of the other pump or switch off the defective pump, while the other pump takes over the work of the defective pump completely in order to keep the head constant or the pressure drop between the pump suction and Compensate the pump outlet side.
  • Such redundancy increases the functional reliability of the system, which advantageously keeps operating and maintenance costs low.
  • FIG. 1 shows a double pump with a housing 1, which has a pump suction side 2b and a pump outlet side 2a.
  • Two pump impellers are arranged in the housing 1 and are each driven by the electric motors 3a, 3b.
  • Regulations 5 are attached to the motor housing as modules by means of screw or snap connections.
  • the higher-level control module 4 is fastened on one control module 5, which in turn is fastened on the control module 5 by means of a snap or screw connection.
  • the higher-level control module 4 has display elements 4a and an input keyboard 4b for setting certain programs or pump circuits.
  • the higher-level control module 4 is connected to the control module of the second electric motor 3b by means of a transmission cable 6 and controls it via the cable 6.
  • FIG. 2 shows a side view of the double pump.
  • FIG 3 shows a possible block diagram of a double pump.
  • the higher-level controller 4 has a CPU, which has a memory, an input option for programming, a display of the program sequence, and the operating states, and a data bus, via which it is connected to the downstream Regulations or as shown in Figure 4 communicates with other pumps or controls them.
  • the actual control is arranged autonomously in the control modules 5 and regulates the engine speed in accordance with the specified target value.
  • the current consumption of the motor is determined by the control and, based on the known pump and motor characteristic curve, the pressure difference p 2 -p 1 currently generated by the pump between the intake port 2b and the outlet port 2a is calculated.
  • the calculated actual value of the pressure difference of the pump is compared with the target value of the delivery head (reference variable) specified by the higher-level control. If the two values deviate, the control tries to adjust the motor speed of the pump accordingly.
  • Each controller 5 is connected to the higher-level controller 4 via an additional communication interface.
  • the controls 5 exchange data with the higher-level control by means of the communication interface.
  • the control unit 5 can report to the higher-level control unit 4 that the respective pump or motor (3a, 3b) is defective.
  • the higher-level controller 4 can also switch the pump into certain operating modes. Possible operating modes are e.g. Standstill, maximum speed or control operation of the pump. So it is possible that one pump delivers at maximum speed and the other pump is operated in normal operation. Another mode of operation is the synchronization of the two pumps, such that both pumps are operated at the same speed. It is also possible that only one pump is in operation and the other is stopped.
  • a pump If a pump is defective, it will alarm the higher-level control 4 via the communication interface, whereupon the higher-level control 4 switches the pumps differently in accordance with the stored program or calculates new target values.
  • FIG. 5 shows a double pump, in which the controls for the two pumps are arranged in a housing together with the higher-level control and the housing is fastened on an electric motor 3.
