The units intended for pumping andensuring the parameters of the circulation of fluid environments require special monitoring during operation. Even the work of one pump sometimes needs to take into account several functional indicators, on the basis of which the decision is made to adjust the treatment of water. The tasks are complicated if several units of different types are involved in the working complex. In this case, it is necessary to use a pump control station, which, on the basis of readings coming through sensors monitoring, will regulate the technical and operational parameters of the system.
What is a pump control station?
By their construction device mostThe stations resemble traditional distribution boards. As a rule, this is a metal cabinet, which is fixed on the wall and, depending on the type of operation, may have access control systems. The internal content provides for the presence of a mounting panel on which the elements of direct control of the units are located.
В стандартной комплектации станции управления pumps have a switch, a microcontroller, a starting device, terminal blocks, transformers and signaling devices - for example, an LED lamp on the panel. Rarely there are panels that do not imply a change in the structure of work items. The configuration of a modern electrical panel allows the user to connect auxiliary sensors and external electrical circuits. This is a typical station performance. But there are other designs that regulate work in simpler and, on the contrary, complex systems.
What are the functions of pump control stations?
The main purpose of such devices is tomaintaining certain pressure parameters at the output of serviced units. The station also connects pumps to frequency converters and switches them in case of power outages. The control of the operating parameters of the frequency converter is carried out by the operator directly from the mounting panel. A separate function is to call the alternation of operating units, which can be performed by the well pump control station and systems designed for surface equipment.
If necessary, increase capacity itemmanagement can use and backup installations. This option is typically provided for systems that service more than two pumps. At the same time, control and management can be implemented either manually, by means of a dispatcher console, or in automatic mode, which deserves special attention.
Features automatic modes
Today, almost no stationscontrols that do not support automatic monitoring of pump operating status. Most of the tasks that are solved in such modes can be performed manually. But there are two categories of functions, designed only for automation. First of all, this is a remote control capability. The operator does not just start and shut down the system, but can also set time intervals until the moment of independent switching.
The second group of tasks concerns emergency modes.Works that support automatic pump control stations in virtually all versions. Thus, when one of the pumping devices fails, the system delivers the corresponding signal to the control panel. At the same time, the station can, without waiting for the operator's response, connect a backup pump or change the operating parameters of the faulty component.
Devices for borehole pumps
For maintenance of downhole unitsmost advanced systems are used. But the requirements for operating conditions are also quite high. As a rule, these are control and protection systems that regulate the water level, focusing on the readings of electronic devices. The indicators are gauges, pressure switches and other elements that monitor operating parameters.
To the most common types of such systemscan be attributed to the control station pump ECV, representing an extensive group of artesian plants. The features of such equipment include increased requirements for installation and enhanced control of the “dry run”.
Surface Pump Systems
Models of such stations are designed to work withsurface pumps. This does not mean that the requirements in this case are reduced, but the emphasis in the design and configuration is not so much on the level of system security as on energy efficiency. So, if the stations of control of submersible pumps provide means for protecting cables and wiring in general, connecting the control panel with electrical units of the units, the control of surface equipment does not at all imply the organization of multi-level networks.
This allows basic communication capacities to be directed to the tasks of optimized management of the water supply system.
Vibrating Pump Stations
In addition to the main functions that are found incontrol systems of pumps of other types, such stations have the means of effective protection against water hammer. In particular, for security measures of this kind, the possibility of a smooth start-up of equipment is used. Also during operation, such systems carefully control the pressure drops, which allows minimizing the risk of breakdowns. For the rest, the vibration pump control station duplicates the capabilities of other panels. It is worth noting that in the families of such systems one can find quite a few household devices designed to support the function of individual water supply lines.
Conclusion
The quality of the operating systempumping water aggregates, depends on many parameters. If we managed to choose the right design of the electrical cabinet and correlate the possibilities of its filling with the tasks, then the borehole pump control station will most likely cope with its functions.
Often there are errors in the organizationwater infrastructure In some cases, the installation crews incorrectly connect to the station, while in others the operators do not comply with the standards for controlling the operation of pumps. Actually, such situations and is due to the active introduction of automatic systems, allowing, if not to solve the problem, then, at least, to notify the service operation.
