Abstract
The utility model relates to a water pump room control system used for automatic production; the method is characterized in that: the system comprises a master controller, a frequency converter, a motor, a water pump and a water supply control circuit between the frequency converter and the motor; wherein, the frequency converter has two, and also include the pressure sensor; the master controller is used for controlling a control circuit of the whole system; and the second frequency converter completes the water supply control task under the low-pressure condition or combines the first frequency converter to realize the control of the two water pumps under the high-pressure condition. The control system can ensure that the motor can run stably under low load all the time, ensure that normal production is not influenced when the motor or the frequency converter breaks down, and also ensure that maintenance personnel can not generate safety problems when maintaining.
Description
Technical Field
The utility model relates to an automated control system field specifically is a water pump house control system for automated production.
Background
Generally, the water pressure control system of water pump room is by total controller, the motor, the water pump, the water supply circuit between converter and the motor constitutes, whole system is connected many water pumps by a converter, but can only let one of them water pump work in the same time at every turn, can make a water pump of work always be in a high load's state when needs higher pressure makes the life-span of water pump and converter shorten, and when the converter appeared damaging, whole water supply system all can be paralysed, when one of them motor broke down, whole circuit anyhow is in the circular telegram state, can produce the security threat during maintenance of maintainer.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned defect, provide a water pump house control system for automated production that reliability, security and life all obviously promoted.
A water pump house control system for automated production; the system comprises a master controller, a frequency converter, a motor, a water pump and a water supply control circuit between the frequency converter and the motor; wherein, the frequency converter has two, and also include the pressure sensor; the master controller is used for controlling a control circuit of the whole system; among the two frequency converters, the first frequency converter completes the control of any one water pump of the main circuit part according to the requirements of the control circuit, and the second frequency converter completes the water supply control task under the low-pressure condition or combines the first frequency converter to realize the control of the two water pumps under the high-pressure condition; the water pump is connected with the frequency converter through the water supply control circuit and is controlled by the frequency converter to complete corresponding actions; the pressure sensor measures different pressure values according to the change of water pressure, feeds the pressure values back to the master controller, sends signals after being processed by the master controller, and then two frequency converters make corresponding reactions to complete the supply.
The control system can enable the two frequency converters to work simultaneously when high pressure is needed, so that the two motors work under low load; moreover, when one frequency converter fails, the other frequency converter can ensure that the production is continued; when one motor breaks down, the circuit where the motor is located can be completely closed and maintained, safety threats cannot be caused to maintenance personnel, and the other frequency converter can work normally.
Drawings
Fig. 1 is a schematic connection diagram of the control system.
Detailed Description
The invention is further illustrated by the following specific examples.
As shown in figure 1, a water pump house control system for automated production comprises a general controller 1, a frequency converter 2, a motor 3, a water pump 4, a water supply control circuit between the frequency converter and the motor 5, a second frequency converter 6 and a pressure sensor 7.
Wherein, the master controller 1 can send out commands and receive feedback signals to realize the control of the whole system, as shown in fig. 1; the 2 first frequency converter can complete the control of any water pump in the main circuit part according to the requirements of a control circuit, such as the frequency converter 1 shown in the figure 1; the 4 water pumps are connected with the frequency converter through a water supply control circuit and controlled by the frequency converter to complete corresponding actions, and the three water pumps in the figure 1 complete the functions; the 5 water supply control circuit is connected with the frequency converter and the water pump, and the frequency converter and the water pump can work orderly and stably as shown in the part between the frequency converter and the water pump in figure 1; the 6 second frequency converters, such as the frequency converter 2 shown in fig. 1, can complete the water supply control task under the low pressure condition, and can realize the control of the two water pumps by combining with the first frequency converter under the high pressure condition; the 7 pressure sensors, such as the pressure sensor in fig. 1, can measure different pressure values according to the change of water pressure, feed the pressure values back to the master controller, send signals after being processed by the master controller, and then make corresponding reactions by the two frequency converters to complete the supply.
The control system can enable the two frequency converters to work simultaneously when high pressure is needed, so that the two motors work under low load; moreover, when one frequency converter fails, the other frequency converter can ensure that the production is continued; when one motor breaks down, the circuit where the motor is located can be completely closed and maintained, safety threats cannot be caused to maintenance personnel, and the other frequency converter can work normally.
