消火栓泵远距离控制分析

译文：
“水是生命之源”，在一次次火魔乱舞、热浪袭人的火灾事件中，人们总会不自觉的产生这样的感慨。事实证明，即使在科技如此发达的今天，水仍然在不同场合继续与火魔抗争。作为水灭火重要形式之一的室内消火栓灭火系统，其控制要求对于建筑电气设计人员来说，就无可争议地摆在了重要位置。对于室内消火灭火栓系统的电气控制，主要表现为对消火栓泵的电气控制。消火栓泵的电气控制分为远距离控制和就地控制。就地控制作为远距离控制的辅助手段及消火栓泵控制的最后保护措施，其重要性，就不再表述：现分析消火栓泵远距离控制如下： 1消防控制中心控制屏控制启停 消防控制中心内的火灾报警控制器在接收到火灾现场的报警设备(如火灾探测器、手动报警按钮以及消火栓报警按钮等)送至的火灾报警信号后，再由控制屏发出联动控制信号，起停消火栓泵。 此种控制方式是根据消防控制屏内部信号处理和逻辑编程来自动实现消火栓泵的起停功能的，布线和控制都比较简单，当然消防控制屏除了自动功能外，屏上还设置有手动控制，能够进行手动操作。 2消火栓报警按钮控制消火栓泵启动 (1)消火栓报警按钮启动消火栓控制电路按消火栓报警按钮的接线形式可分为两类即串联和并联接法： A．串联接法：按钮表面装有一有机玻璃，按钮盒内有一常开触点和一常闭触点，利用其常闭触点实现报警和启动消火栓泵。 B．并联接法：按钮表面装有一有机玻璃，按钮盒内有一常开触点和一常闭触点，利用其常开触点实现报警和启动消火栓泵。 下面以消火栓报警按钮通过消防控制屏启动消火栓泵(另有消火栓报警按钮直接接在消火栓泵控制箱控制回路的接法)分析其控制过程。 火灾报警控制系统运行时，消防控制屏的消火栓控制部分转换开关切换至自动位置。正常状态下，继电器线圈KA2得电，常闭触头KA2变为常开，继电器线圈KAl无法通电，对消火栓泵无控制输出。火灾状况下，按下任一消火栓报警按钮，则使继电器KA2失电，常闭触头KA2复位，使得继电器KAl得电，其常开触头KAl闭合，接通消火栓报警按钮上的启泵指示灯，同时对消火栓泵实现启泵操作。停泵可由消防控制屏上的转换开关切SAl换至“零位”，实现消防控制屏上停泵。 火灾报警控制系统运行时，消防控制屏的消火栓控制部分转换开关切换至自动位置。正常状态下，继电器线圈KA2失电，继电器线圈KAl无法通电，对消火栓泵无控制输出。火灾状况下，按下任一消火栓报警按钮，则使继电器KA2得电，常开触头KA2闭合，使得继电器KAl得电，其常开触头KAl闭合，接通消火栓报警按钮上的启泵指示灯，同时对消火栓泵实现启泵操作。停泵可由消防控制屏上的转换开关SAl切换至“零位”，实现消防控制屏上停泵。 (2)消火栓报警按钮启动消火栓泵控制电路按消火栓报警按钮的接线路径可分为两类：即消火栓报警按钮直接与消防泵控制箱相连接法和通过消防控制屏启泵接法(通过消防控制屏启泵接法上面已分析)。 以下分析消火栓报警按钮直接引入消火栓泵控制箱的控制方式。 现在消火栓报警按钮直接接入泵控制箱的做法，绝大部分采用了变压器将泵控箱的交流220V变送为安全电压方引入消火栓报警按钮盒(避免高电位在灭火现场产生伤人事故)。而其串联接法也是利用常闭触头，使线圈KA2在失电状态下，由其常闭触头接通控制电路(与通过消防控制屏进行控制消防泵的原理相同，不再详述；并联接法亦然。)。但值得注意的事，此种接法中尚有不足之处，即利用消火栓报警按钮直接启泵后，在按钮未复位的情况下，无法在消防控制屏上进行停泵操作，不满足现行规范要求。 综合以上分析，不难看出，在消火栓报警按钮工作方式不同的情况下，由消火栓报警按钮直接启泵的控制显然有所差别，设计和施工中应引起重视。消火栓泵远距离控制不仅涉及消防报警系统也对强电设计提出一定要求，控制电路的选择或设计还应考虑各自系统工作方式的不同点，进行有针对性的处理。

"Water is the source of life", in a second Huomo Flurry was very hot fire incident, there will always be unconscious have such a feeling. Facts have proved that, even in science and technology is so advanced today, the water still continues to work with Huomo fight on different occasions. As one of the important forms of water, indoor fire hydrant fire fighting system, its control requirements for the building electrical design staff, as far as the undisputed placed in an important position. Fire extinguishing for indoor elimination bolt system, electrical controls, mainly for the electrical control of the fire hydrant pump. Fire hydrant pump G Series Inline Centrifugal Pumpelectrical control into remote control and local control. Local control as a remote control, auxiliary means and the last fire hydrant pump control protection measures, its importance, is no longer presentation: We now analyze the fire hydrant pump remote control is as follows: A fire control center control start-stop control panel Within the fire control center receives a fire alarm controller in the field of fire alarm equipment (such as fire detectors, manual alarm button and the alarm button, fire hydrant, etc.) sent to the fire alarm signal, and then sent by the control panel linkage control signal, since Stop fire hydrant pump. This control method is based on the fire control panel within the signal processing and logic programming to automatically stop the fire hydrant from the pump function, wiring and controls are relatively simple, of course, the fire control panel addition to automatic functions, screen is also installed with manual control, capable of manual operation. 2 alarm fire hydrant fire hydrant pump start button control (1) fire hydrant alarm button to start the fire hydrant fire hydrant alarm button control circuit wiring according to the form can be divided into two categories namely, serial and and join law: A. Series Connection: Button with a plexiglass surface, the button box there is a normally open contact Model IR Single Stage Single Suciton Hot Water Centrifugal Pumpand one normally closed contact, normally closed contacts to achieve using its alarm and start the fire hydrant pump. B. And the connection method: the button with a plexiglass surface, the button box there is a normally open contact and one normally closed contact, normally open contacts to achieve using its alarm and start the fire hydrant pump. Buttons below to fire hydrant by the fire alarm control panel to start the fire hydrant pump (fire hydrant otherwise directly connected to the alarm button, fire hydrant pump control box control loop of the next method) analysis of the control process. Fire alarm control system is running, the fire control panel switch control part of the fire hydrant to switch to the automatic position. The normal state, the relay coil KA2 have electricity, and often close contact KA2 into a normally open, relay coil KAl no electricity, no control of the fire hydrant pump output. Fire conditions, press any one fire hydrant alarm button, so that relay KA2 lost electricity, and often close contact KA2 reset, making relay KAl have electricity, its normally open contact KAl closed, connected to the fire hydrant alarm button the Kai pump light, while achieving Kai hydrant pump pump operation. Pump shut down by the fire control screen for the conversion to open concerns SAl to "zero" and realize the fire control panel on the pump shut down. Fire alarm control system is running, the fire control panel switch control part of the fire hydrant to switch to the automatic position. The normal state, the relay coil KA2 loss of electricity, relay coil KAl no electricity, no control of the fire hydrant pump output. Fire conditions, press any one fire hydrant alarm button, so that KA2 was electric relay, normally open contact KA2 closed, making relay KAl have electricity, its normally open contact KAl closed, connected to the fire hydrant alarm button the Kai pump light, while achieving Kai hydrant pump pump operation. Pump shut down by the fire control panel on the switch SAl switch to "zero" and realize the fire control panel on the pump shut down. (2) The alarm button to start the fire hydrant fire hydrant pump control circuit wiring according to the fire hydrant alarm button, the path can be divided into two categories: alarm button fire hydrant and fire pump control box directly connected to law and the adoption of the fire control panel Kai Pump Connection (through the fire control Ping Kai pump has been connected in the above analysis). The following analysis alarm button fire hydrant fire hydrant pump control box directly into the control mode. Now fire hydrant alarm button and direct access to the practice of pump control box, most used transformer to 220V AC pump control box for secure transmission voltage side into the fire hydrant alarm button box (to avoid high-potential injury accident resulting in fire-fighting scene). And its series-connection makes use SG Series Inline Centrifugal Pumpof the often close contact, so that the coil KA2 in the loss of power state, its normally closed contact connected to control circuitry (with the adoption of the fire control panel to control the fire pump on the same principle, will not speak; and mindful of the Law no different.). It is noteworthy that matter, then such laws are still inadequate, that the use of fire hydrant Kai pump directly after the alarm button, the button does not reset the circumstances, can not stop the fire control panel on the pump operation, does not meet the current standards requirements. Summarizing the above analysis, it is easy to see that work in the fire hydrant alarm button, under different circumstances, from the fire hydrant alarm button on the control of the direct Kai pump, apparently, differences in design and construction should be attention. Fire hydrant pump remote control not only the fire alarm system is also designed to make certain of the strong electricity demand, the control circuit to select or design their own system of work should also take into account differences in the way points, carry out targeted processing.
