Overview of operation principle of integrated prefabricated pump station and products of integrated pump station
The pump station of gravity pipe network should adopt automatic liquid level control; Pump station drainage after lifting the medium relying on fluid gravity as power transmission network pump station should adopt automatic liquid level control, most of the current situation is this kind of control. That is, when the water level gradually rises, the liquid level float also rises with the rise of the water level. When the water level rises to the set high water level (start the pump), a water pump starts to run. Then the water level drops. When the water level stops to the low water level (stop the pump), the water pump stops running and the operation is repeated alternately. At this time, if the water level does not fall but rises, when it reaches (ultra-high water level), the two pumps will run at the same time. When the water level drops to the low water level (stop pumping), the two pumps will stop, and the above process will be repeated when the water level rises.
Integrated prefabricated pump station, integrated pump station product overview equipment control
◎Hardware: The pump station adopts programmable controller PLC combined with the touch screen with excellent performance, combined with multiple pumps flexible combination of automatic drainage lifting pump station, according to the detection of water level to automatically adjust the operation of single pump or multiple pumps to meet the needs of drainage, the whole system is always in the state of high efficiency and energy saving. The control system program adopts modular design.
◎Controller (optional) : with very high cost performance, can give full play to its powerful function in small automation system, can expand the digital quantity and simulation of the module, can connect the touch screen, responsible for handling all the system logic switching and operation, fault display and automatic operation，
◎BA interface (optional) : The standard signals provided by the pump station control system include all pump operation signals, fault signals, manual/automatic signals (all dry contacts) and level signal outputs (4~20mA). The system provides standard total start/stop signals (24VDC or 24VAC relays & GT).
◎Software: The standard 4~20mA signal is transmitted through the sensor, which can realize the automatic control of the each pump.
◎Three working modes: Manual-Stop-Automatic: Each water pump has three working modes: manual-stop-automatic. Each water pump can be started manually, but the water pump will not run when stopped

Integrated prefabricated pump station, integrated pump station product overview performance parameter description
◎The pump head used by the pump station is not conventional according to customer requirements.
◎The number of pumps used in the pumping station is determined according to the actual demand. There is no conventional supporting system, and single or multiple pumps can be used simultaneously or in rotation.
◎The diameter and height of the pump station are not the key, but the effective volume of the pump station, which can be modified according to the actual needs of the customer.
◎According to the national drainage pumping station design requirements of comprehensive consideration, the effective volume calculation. The effective volume between pump start and pump stop liquid level should be determined according to the number of starts and stops 6~7 times per hour. The starting water level needs to consider the operating conditions of the pump. Therefore, the effective volume of the pump station is only related to the number of start and stop of the supporting pump and the design flow of the pump station. The effective volume shall not be less than the flow of a single pump in 5 minutes, as long as it meets the formula, which is also the difference between the integrated pump station and the traditional pump station, the effective volume is small, reduce investment.

Integrated prefabricated pump station, integrated pump station product overview perfect automatic control system
In addition to the functions of self-detection, self-control and self-protection necessary for outdoor or field work environment, the integrated prefabricated pump station also has intelligent functions such as data remote transmission, automatic storage, automatic alarm, manual intervention, log recording, historical data query, remote login and hierarchical management.
Through various sensors installed in the internal of pump and pump station to transmit signals to the data acquisition and control module, data acquisition control module to filter out comprehensive judgment, after take out the useful signal interference signal of water pump control instruction, at the same time, the collected data through the GPRS module to wireless data flow on the way to the remote server. After receiving the data from the pump station, the remote server classifies and stores the data. Authorized users can log into the server through the client anywhere to consult the real-time and historical data of the sensor, and can forcibly intervene the operation of the pump station according to the actual situation. The system reserves automatic alarm setting options, through wired or wireless signals to the specific personnel's computer or mobile terminal alarm.
