DESCRIPTION_LONG

Tender text

Pressure boosting system as a fully automatic compact unit for fire fighting purposes in accordance with EN 12845. Consisting of 2 pumps (main/standby) with horizontal base frame - EN 733 - with spacer coupling, electric motor and multistage vertical electric jockey pump, diaphragm pressure vessel (capacity: 20 l) and one switch cabinet per pump, fixed to a robust support structure. Two models SC-Fire E for the electric motors, both equipped with Smart Controller, plus model SC-Fire J for the jockey pump, solid construction made of special profiled parts with cut-outs for forklift trucks and hooks to ensure trouble-free, safe transportation. Height-adjustable bracket for the outlet manifold, special base frame which reduces the transfer of vibrations considerably and increases the reliability and service life. A circuit with dual pressure switch, pressure gauge, non-return valve, valve (secured from use by unauthorised personnel) for the main pump and standby pump for automatic start. The cables are concealed in the construction and protected against bumps and cuts. Equipped with a diaphragm installed directly on the main/standby pump housing as standard, to prevent overheating in the event of zero flow. Two switchgears SC-Fire E and an SC-Fire J for fire extinguishing systems in accordance with EN 12845. Switchgears integrated in a sheet metal enclosure in accordance with protection class IP54. Very high quality control system and particularly easy operation thanks to SC Fire control, with symbol-based LC display, easy user interface with simple menu navigation, pressure and rotary switches for quick adjustment of parameters. Communicative control unit for monitoring system operation. The system has been mounted on the base frame with wires and pipes are ready for connection. Intake pressure: The maximum intake pressure must be taken into account when designing the system configuration (see Technical data). The maximum permissible intake pressure is calculated from the maximum operating pressure of the system minus the maximum delivery head of the pump at Q = 0. For sprinkler systems in accordance with EN 12845, the water pressure should not exceed 12 bar. In sprinkler systems with a pronounced slope, in which the difference in height between the highest and lowest sprinkler is more than 45 m, the water pressure can be higher than 12 bar at the pump outlet or in the piping, provided that all of the system components are designed for this pressure level. Installation of the pressure boosting pump under suction conditions. For the main/standby pump, it is necessary to install a supply tank with connection to the discharge pipe above the pump. Volume flow Up to 750 m³/h (208 l/s) system configuration for the main/standby pump. Switchgears/control devices for fire water supply systems Wilo-Control SC-Fire E (main pump or standby pump with electric motor) Hardware: Fully electronic central control unit, installed in a painted steel enclosure, protection class IP54, control and display devices on the front door Features and functions: The design of the control device depends on the power of the connected pump (start via DOL or star-delta connection). The device comprises the following components: *Main switch: For switching the switchgear on and off. (For unauthorised use in the event of a fire) *Display: Display built into the door of the switch cabinet for operation and display purposes. Shows the operating data and the operating status of the pump and control unit through a combination of symbols and numerical codes. Menu selection and parameter input is effected via the red button *Microprocessor with Soft PLC: Microprocessor PLC (Soft PLC), realised through programming, the power supply unit and the I/O wiring. The programming configuration depends on the system and the sprinkler system *Indicators: Longlife signal lamps indicate the operational readiness and operation of the pump, the activation of the pressure switch and the float switch, a false start, a collective error, manual start and manual stop *Buttons: Push buttons for manual start and manual stop, the lamp test and acknowledgement of alarms and warning messages *Fuse protection: Fuses which tolerate the starting current for at least 20 s *Motor startup: Contactor for direct-on-line starting, up to 22 kW, for higher power levels start via star-delta connection *Motor protection: Only for signalling *Monitoring of the water supply: By means of a float switch to ensure a minimum water level of 2/3 of the supply tank is always maintained *Performance monitoring: Power supply and performance of the pump *Combined signal report: All types of error are displayed via a common error indicator *Individual signal report: The important false start error message is displayed via an individual error indicator *Error message and acknowledgement: All error messages are displayed via LEDs, shown in the display as an error code and must be acknowledged Software: *Factory-programmed for fully automatic operation *Information regarding voltage, electric current and power of the pump *Menu navigation with symbol representation Conforms to the following standards: *Fixed firefighting systems - Automatic sprinkler systems (EN 12845), part for pumps with electric motor *Electrical equipment of machines (EN 60204-1) *Low-voltage switchgear and controlgear assemblies (EN 61439-1 and EN 61439-2) *Electromagnetic compatibility (EMC) — Immunity for industrial environments (EN 61000-6-2) *Electromagnetic compatibility (EMC) — Emission standard for residential, commercial and light-industrial environments (EN 61000-6-3) Function description: Wilo SC-Fire E control devices can be used to control pumps with an electric motor, sensors for pump management and the level of information. The SC-unit is controlled via a microprocessor with Soft PLC. It is used to control and regulate the necessary functions of pressure boosting systems for fire fighting in accordance with EN 12845 for test purposes and operation of the sprinkler system. The operating logic for the fire extinguishing system is based on the cascade calibration of the pressure switches for starting the pump. If a large amount of water is requested due to the opening of one or more circuits or due to a defective sprinkler, the pressure in the system decreases. The SC-Fire controller then initiates a startup of the main pump. If the electric main pump does not start in systems with multiple pumps (for example due to problems with the power supply), the pressure switch of the standby pump is activated by the drop in pressure and the pump starts. In some cases, two or more electric pumps can be used. As soon as the sprinkler circuit or gate valve via which the sprinkler heads are supplied is closed, holding pressure (static pressure) is built up in the system. The stop buttons on the SC-Fire must then be actuated to stop the main and standby pump. Additional information: A significant advantage offered by the Smart Controller SC-Fire is the user friendliness of the tried and tested Wilo red-button technology. At the heart of the SC is the Soft PLC programmable logic controller, which is based exclusively on Wilo's wealth of experience. All programming is implemented internally. These next generation control devices can therefore be used flexibly and fulfil customer-specific requirements in all markets. Wilo-Control SC-Fire J (jockey pump with electric motor) Hardware: Fully electromechanical control unit, installed in a painted steel enclosure, protection class IP54, control devices and buttons on the front door Features and functions: The design of the control device depends on the power of the connected pump. The device comprises the following components: *Main switch: For switching the switchgear on and off *Indicators: Longlife signal lamps, which indicate the operational readiness of the pump, operation of the pump and collective errors *Switches: Rotary switch for setting the manual mode or automatic mode *Motor startup: Direct contactor *Motor protection: Switch for protection against short-circuits and overloads *Individual signal report: Motor error message (short-circuit, overload) *Error message and acknowledgement: The motor error message is indicated via corresponding LEDs. The error is acknowledged when the motor protection switch is restarted Conforms to the following standards: *Fixed firefighting systems - Automatic sprinkler systems (EN 12845), part for jockey pumps *Electrical equipment of machines (EN 60204-1) *Low-voltage switchgear and controlgear assemblies (EN 61439-1 and EN 61439-2) *Electromagnetic compatibility (EMC) — Immunity for industrial environments (EN 61000-6-2) *Electromagnetic compatibility (EMC) — Emission standard for residential, commercial and light-industrial environments (EN 61000-6-3) Function description: Wilo-Control SC-Fire J units can be used to control jockey pumps with an electric motor and sensors according to EN 12845, as well as for test purposes and operation of the sprinkler system. The operating logic for the fire extinguishing system is based on the cascade calibration of the pressure switches for starting the pump. The jockey pump, which is used for pressure boosting, is started first and ensures that the system is filled with water and that it remains pressurised. It is activated in the event of a pressure drop in the system. A properly calibrated pressure switch is used for controlled starting and stopping procedures.
