First, the working principle and use of ZSJZ water flow indicator :
ZSJZ series water flow indicator is used for automatic sprinkler system. It can be installed on the main water supply pipe or crossbar water pipe to give an electrical signal of water flow in a small area in a certain area. , Can also be used to start the fire pump control switch. The water flow indicator series products produced by our factory are ZSJZ (type A) with delay circuit and ZSJZ (type B) without delay circuit. Each model has: Six specifications for different pipelines. Water flow indicator with delay circuit. The delay time is adjusted to 58s at the factory. If the user needs other time, our factory can supply it according to requirements. The connection methods are: pipe thread, welding, method Three types of blue are available for users to choose.
Second, ZSJZ water flow indicator technology picture:
Main technical parameters of ZSJZ water flow indicator :
1. Voltage: DC24v 2. Control capacity: 10w 3. Action flow: 15-37.5Lmin 4. Rated working pressure: 1.2Mpa
5. Delay time: 2-90s (adjustable) 6. Power consumption: <200mA (when alarming)
Fourth, ZSJZ water flow indicator installation and maintenance:
1. ZSJZ type (thread type) installation of water flow indicator adopts T-shaped pipe thread connection. The middle thread of the T-shaped pipe is connected with the water flow indicator, and the other ends are connected with the pipe. This product is suitable for three diameters of 50, 65 and 80.
2. The ZSJZ type (welding type) water flow indicator is installed at a predetermined position, and the holes are drilled according to the product specifications. Then the water flow indicator base is removed and welded to the pipe, and the iron knob on the inner arm is removed. The drilling size is 80 For the following specifications, drill holes are 33mm, and drill holes above 100mm are 48mm.
3. The ZSJZ type (flange type) water flow indicator is installed with a tee flange directly connected to the pipe flange. It is suitable for pipe diameters of 100mm and above, and the length of the tee is 180mm.
4. Wiring, press the line end "+" red line to the power supply "+" DC24V, "-" end black line ground wire "normally open" end yellow wire to the alarm system signal end, the "common point" blue line can be used to reduce leads The "+" ends are connected.
5. When connecting the water flow indicator pipeline, it must be ensured that the length of the straight pipe before and after is not less than 5 times the diameter of the pipeline. During installation, ensure that the water flow indicator is perpendicular to the horizontal center of the pipeline. The direction of the arrow on the nameplate should be consistent with the direction of the water flow. Oral debugging and periodic inspection can open the end-of-zone test device, discharge the water flow for simulation test, and check whether the water flow indicator has been modified. If a failure is found, the water flow indicator and alarm device should be checked separately to eliminate the failure and put the system in a servo state. .
