< < < --Low-voltage cabinet series technical parameters<, can be programmed when a fire alarm occurs When the program controller receives the fire command, the inspection cabinet automatically stops working instantly and at the same time sends a signal to start the fire distribution cabinet to supply power to the fire water pump [--low voltage cabinet series] to achieve the function of extinguishing fire.
<, star-delta start control cabinet
<, start and stop of fire pumps. Traditional fire pump control cabinets generally realize this control method through multiple intermediate relays and time relays in the secondary circuit. Although the cost is Lower
<, timer setting. Press the timer key to enter the timer on function setting. At this time, the timer is on and the hour position is flashing. Press the r key to adjust the hour and then press the timer key again. The minutes are flashing
<. Design and production in accordance with "Code for Fire Protection Design of Buildings" and "Code for Waterproof Design of High-Rise Civil Buildings"
<. The installation beam can also be installed in the cabinet without using a mounting plate (optional).
< . The automatic fire alarm and fire linkage control system mainly consists of the following equipment: host motherboard, loop card, manual control panel, multi-wire control panel
< . When a trial alarm is required: remove the alarm port Control the locking device of the ball valve between the retarder and the retarder and close it.
< , Working environment temperature: -℃~+℃
< , Advantages: With single-chip microcomputer control as the core, low cost and high integration.
< < --Functional features of low-voltage cabinet series<, Electrical appliance inspection content: Electrical appliance main circuit monitoring, power supply voltage, current, phase loss, insulation resistance, voltage withstand, etc.
< , If we can master the core technology through independent research and development, on the one hand, we can improve and upgrade the existing automatic inspection control equipment
< , "Technical conditions for single and double-sided printing boards without metallized holes" 》
< , the integrity of fire-fighting equipment and fire-fighting systems. Whether the fire-fighting equipment of each department is well managed, used well and replaced when expired ensures that it is complete and usable.
<, in order to make up for the serious consequences of the fire pump not being able to start due to corrosion and other reasons due to long-term idleness, causing great losses to national property and people's life safety.
< , intelligent fire inspection complete set of cabinet components
< , fire alarm system and other fire alarm equipment are used to judge the fire situation and give alarms. The purpose of the alarm is to confirm the fire situation and provide early warning. Put out the fire.
< . Places for commercial activities should be set up in the passenger evacuation area, platform and evacuation passage of the underground station.
< , To make up for [--Low Voltage Cabinet Series] in the fire protection system, fire water pumps and fire fans will not be started due to long-term idleness due to corrosion and other reasons. Automatic rotation, etc. It is also equipped with a working status (manual, automatic) selector switch
< < --Working principle of low-voltage cabinet series<, and the mandatory requirements of industry standards can only be produced, sold and used after passing the certification.
< . The control equipment can inspect the fire pumps one by one according to the cycle and time set by the inspection controller. The running time of each pump should not be less than
< . The control cabinet box requires a control cabinet. There should be a functional label on the door. The label is a piece of colorless and transparent plastic material with a thickness not less than that after chamfering. The back of each label should be engraved and painted.
< . Automatic fire sprinkler systems are divided into two types: smoke-sensing type and temperature-sensing type.
< , Operators only need to operate the computer in the control center to learn the working conditions and various technical parameters of the outdoor pump unit and other equipment
< , D series fire pumps have passed the National Fire Equipment Quality Supervision and Inspection Center The test has been certified and qualified for sales in the Chinese market.
< ,: [--Low-voltage cabinet series] Alternate automatic switching/manual switching
< , But countless experiences and lessons have proven that the success of initial fire fighting mainly depends on the integrity of this part of the equipment. or not. The characteristic of fire water supply equipment is that it must function once it is not used normally or even for a long time.
< The main parameters of the water pump are: the unit of flow is / /. The unit of expression for lift is. The necessary NPSH parameters for clean water pumps are very important, especially when used in suction-type water supply equipment. The rated current parameters of submersible pumps are very important, especially when used in variable frequency water supply equipment.
< , Water pump inspection speed is adjustable (~r/min)
