Rain quickly extinguishing equipment in the Chemical Production Line


/ O control, spray intervals. For example,[link widoczny dla zalogowanych], suspended second spray l5 l5 seconds. Discharge disk: 360 spray angle. . Spray time by the MC / o the electronic switch control,[link widoczny dla zalogowanych], the action time of less than 4O milliseconds, but the design of a one-time use of the occasion in a selected discharge tray detonation. Use in explosive situations pilot nozzle. Fourth, the application cited cake with the development of industrialization, industry, fires and accidents, just to forecasting and detection of protection system can not meet the needs of production and protection. Fire protection systems must be rapid fire, the destruction of the equipment reduced to a minimum. Kazuya devices with fast rain off the fire as soon as possible to play the role of fire. Chemical manufacturer of fire, security barrier distance can be reduced to reduce the footprint. Production line speed of a chemical system to indicate rain circle, as shown in Figure 6.1 occurs when the transport of materials spark, then measured by infrared expel M-C / o control treatment, the pilot solenoid valve spray 5.1 release fixed field System Field waist 5-2PN bite first join Tianzuo, PN nozzle sprinkler media. Since the electromagnetic valve control by three water spray nozzle, thus constituting a suppression range, run the sprinkler system is very reliable links. If the process is not very strict requirements, you can not interrupt process, spraying dozens of seconds, the solenoid valve closed,[link widoczny dla zalogowanych], spray stop, the production continues. When the process is demanding and can immediately stop the process, to ensure production safety barrier. When the fire chemical production line, there are dangers of large, easily lead to dangerous city of alkaline processes used to vent comb plate (EDD), as shown in Figure 6.2. , Instead of using the discharge valve plate guillotine can probe the distance between devices and the fire area reduced to 3 meters. Thrust measured particle detector when the spark, MC / o control the release of fire water discharge valve to form a protection zone,[link widoczny dla zalogowanych], and immediately stop the process, the release time of less than 4O ms. Fifth, fast rain spray test time can play a role in rapid fire, in addition to its accuracy, there is an important - 25 - I., Chen cried the first 55 pilot 1. Si core 2. Gasket 3. Body 4 - connection head 5. Connection pipe 8. Connection nut 7. Xiao body spray 8. Float Film shunt block 0l 0 Ji exposed pad anonymous structure field 5.4FEDD technical indicators, the spray time. Spray time means: to detect the source of fire to the nozzle opening time. Information requirements, PN action nozzle Tian ship should be less than lOO mm. EDD operating time of the nozzle should be less than 40 milliseconds. 26 from the field for a l1010Z050/60 old f 6. 'Cried the production dimension first and then release the power PN few home from October 1987 to May 1990, we have repeatedly PN nozzle on the production line were tested. January 1987 1O now the test results and methods are described below guillotine by the probe onto the MC / o control the membership for the electronic transmission speed, time of less than l ms. Figure 7.1 shows the open 『] signal source for the l10-volt soap. Electronic pressure switch close signal from the record of action milliseconds asked. Jia left the test results, see Table 27. After several guillotine test, the time could keep 40rns below. EDD technical complexity of the test nozzle. However, in theory, should be less than 40ms. Sixth, there is a hard thing to ask Si Yuan note ring nozzle 6.2 EDD line electronic pressure switch to indicate ring】 0v I sprayed electrical Wei Tin 7.1 {l 'Pa when the business model l1PNN number of field test of time mB13.8l8.92o l234512345 . 719.3l4.6l1.1llI. 414.618.7l5.56.1 problems 6.1.1EDD: sprinklers have detonator misfire problem of broken glass or breakable. 6.1.2 detector malfunctions. 6.1.

Therefore, to increase the regulator. 6.2.2.2 Access to the system requirements for a strong establishment of a separate grounding do not side with the work of grounding, lightning protection in connection with wires. 6.2.2.3 Radio playing away from strong, strong radio signal is likely to cause afternoon on the detector.
