Technical parameters of fault protection inspection cabinet 3
/> , The multi-line fire telephone system does not have a telephone receiving module [fault protection inspection cabinet 3].
The water pump control cabinet fully absorbs the advanced experience of water pump control at home and abroad. After years of production and application, After continuous improvement and optimization, it is carefully designed and produced. The product has various protection functions such as overload, short circuit, phase loss protection, pump body water leakage, motor overtemperature and leakage, and complete status display. It also has single pump and multi-pump control working modes, multiple main and backup pump switching methods and various Class startup mode. It can be widely used in automatic control of water supply, drainage, fire protection, sprinkler pipe network pressurization, HVAC hot and cold water circulation and other occasions in industrial and agricultural production and various buildings. The water pump control cabinet has excellent internal quality, beautiful and durable appearance, and is easy to install and operate. It is a safe and reliable companion for all types of water pumps.
Customers often ask when receiving quotations from Zhenjiang Ouling Electrical Automation System Equipment Co., Ltd.
We can try to explain from the following aspects: There are drive systems and control systems in the fire inspection cabinet. , input and output system. The control module in the fire inspection cabinet cannot alone command the fire inspection cabinet to perform inspection actions.
After receiving the fire command, the programmable controller will automatically and instantaneously stop the inspection, start the fire pump, and manually shut down the fire after the fire. .
In the next few years, my country's fire protection industry will continue to show a rapid growth trend, with an annual growth rate of up to
. Number of control motors: - units
. There is no basic platform software with independent intellectual property rights. For this reason we have to spend a lot of money to buy from abroad. As a result, Chinese companies in the fire protection industry not only make less money, but are also subject to the international market.
The low-frequency and low-speed digital intelligent fire automatic inspection control cabinet solves this problem very well, providing enterprises and countries with the best quality products and services to meet actual needs.
When a large current flows through the stator coil and rotor cage bars of the motor, the maximum current is reduced by about half, and the instantaneous heat generation is only about 1/2, and the insulation life will be greatly extended
Fault protection inspection cabinet 3 functions Features
Power frequency inspection can reflect the actual operating conditions of the fire pump, but it consumes a lot of power during inspection, has high cost of use and may have adverse effects such as overpressure in the pipe network, so this inspection method Not used often.
The one-way valve disc of the system is damaged or stuck by debris
The damage rate of closed stairwells and smoke-proof stairwell doors in high-rise buildings with densely populated places exceeds 1.
. According to the characteristics of high integration and small size of the single-chip microcomputer, the main program of the control system is written into the single-chip microcomputer chip.
Using microcomputer control technology, it has advanced technology, high reliability, strong functionality and easy operation. Simple
The fire intelligent digital inspection equipment outputs inspection instructions to inspect the main circuit one by one [fault protection inspection cabinet 3]. The inspection return signal is taken from the main auxiliary contacts of each electrical component.
The digital intelligent fire inspection control equipment will provide data remote transmission, image monitoring, fault alarm, information printing and other functions for all the above functions.
It consists of a frequency converter, a pressure transmitter and a pressure transmitter and several auxiliary components.
. Mode conversion: Press the mode key to cycle between automatic mode and manual mode.
. Check the power incoming line to ensure that the three-phase power supply is connected to the control equipment.
Working principle of fault protection inspection cabinet 3
Fire hydrant system: This system is one of the main equipment for fire fighting. When the system is operated.
, with automatic and manual inspection functions, the automatic inspection cycle should be set as needed.
Overview of fire control cabinet: With the continuous improvement and development of the construction industry, Liangbang Company has launched a series of water pump inspection fire control cabinets in accordance with national standards and using the latest achievements in control technology.
Factory inspection requires companies to provide many documents, and colleagues have strict requirements for factories. We will send professional engineers to the factory site to prepare the necessary documents
to destabilize the power grid. The starting current contains a large number of high-order harmonics, which will cause high-frequency resonance with the power grid circuit parameters, causing relay protection malfunctions, automatic control failures and other faults. .
It can also realize hot backup dual control system for fire inspection (optional) or remote computer real-time image display of system status.
, Thermal relay should meet the requirements of relevant clauses. The bidder should provide time current characteristic curve. Curve tolerances should not be exceeded. The set current range of the thermal relay should include the rated current of the motor.
, Inspection execution [fault protection inspection cabinet 3] mechanism is a low-speed drive fan unit, which will not cause mechanical impact on the fan, especially for high-power fire fans
, ramp voltage starting, constant current Soft start is optional
, and this pressure switch has a signal line that is interlocked with the fire pump, and the pump starts automatically. Then the sprinkler pump supplies the water from the pool to the pipe network through the pipes, and the entire fire protection system starts to work.
