The communications command vehicle is an indispensable equipment for us during disaster relief and drills. It is responsible for major rescue command tasks and can provide a powerful communication and communication tool for disaster relief sites. What are the functions of the communications command vehicle? Take a look at the specific introduction.
First, the communication security function. The basic function of the communication command vehicle is to ensure the smooth progress of the communication work. It is necessary to do a good job of sending and receiving information. The information on the rescue site is transmitted to the general command center through voice, pictures, video, etc., and the command center must also receive the information. Information to help better deal with the work of the disaster scene. The communication function is the most important function of the communication command vehicle. On the one hand, it must accurately record the situation on the scene, and it must also ensure the accuracy and security of the information. It must ensure that the information received and sent is not damaged or interfered. The modern communication command vehicle has very advanced equipment, radio systems, satellite communication systems, etc., which are necessary tools to ensure the smooth progress of communication. Advanced equipment can ensure the realization of communication functions.
Second, combat command function. Another great feature is the command communications command vehicle, the car has a separate area of the meeting room, control room, etc., to provide protection to give full play to the role of the command vehicle. The reasonable and effective command at the disaster site is of great significance for rescue work. The command vehicle is equivalent to a mobile platform. It can be transferred to different disaster-relief areas at any time as required. It assumes the task of issuing command orders to take over the entire situation and is used at the disaster relief site. Great effect.
Third, the basic functions of the vehicle. As a professional vehicle, the communication command vehicle has the basic transportation function of the vehicle. On this basis, it also needs to have good stability and adaptability. It must be able to adapt to different road conditions in order to be able to cope with the complicated disaster area environment. The safety of vehicles must also be ensured, and there should be good performance in terms of seismic stability, stability, etc., so as to provide a stable working platform for communications command.
Boiler auxiliary equipment mainly includes water supply equipment, ventilation equipment, fuel supply, slag removal and dust removal equipment, steam and water pipes and accessories, detection instruments and automatic control equipment.
1. Water supply equipment
It is composed of water treatment equipment, water supply tank and feed pump 24. Water treatment equipment is used to remove impurities in water, such as oxygen, calcium and magnesium ions, to avoid scaling and corrosion on the inner wall of steam boiler, and to ensure the quality of boiler water supply. The treated boiler feed water is lifted by the feed water pump and then sent to the upper drum through the economizer.
2. Ventilation
The ventilation equipment includes air supply fan, induced draft fan and chimney. Its function is to provide air for mule fuel combustion and lead out combustion product flue gas from the boiler, so as to ensure the normal combustion, and make the flue gas wash the heating surface at the necessary flow rate of 7a68696466fe78988e69d8331333433626465 to strengthen heat transfer. Finally, the stack with a certain height will exhaust the smoke to the atmosphere to reduce the smoke pollution and improve environmental health.
3. Fuel supply, slag removal and dust removal equipment
This is for conveying fuel to boiler, removing ash and purifying flue gas. Belt conveyor, ash conveyor, ash truck and dust remover, etc. For boilers that need to be pre processed with fuel, fuel preparation such as screening, crushing and coal grinding shall also be included. In addition, the dust remover or flue gas desulfurization and denitrification device installed in the flue at the tail of the boiler is an indispensable auxiliary equipment to reduce the smoke pollution and protect the environment.
4. Check instruments and automatic control equipment
In addition to water level gauge, pressure gauge, safety valve and other instruments installed on the boiler body, in order to supervise, regulate and control the safe and economic normal operation of the boiler equipment, a series of instruments, automatic boiler feed water regulating device, automatic fuel combustion control device, etc. are often installed. Some boiler rooms are also equipped with industrial television and remote control device and even more modern automatic control system, more Scientific supervision. Control boiler operation.
Boiler auxiliary equipment, not every boiler is equipped completely, but with the boiler capacity, type, fuel characteristics and combustion mode as well as water quality characteristics and many other factors to adapt to local conditions, adapt to the times, more practical requirements and objective conditions.
