Industrial Laser Distance Sensor
Industrial
Laser Distance Sensor, we also call it secondary development laser distance
module, which support TTL level and CMOS. The laser range sensor can be widely
used in professional surveying, mapping, construction, robots, hunting arrows,
industrial monitoring and automated measurement applications in electricity,
transportation, etc. Our laser distance module supports data communication with
RS232, USB with a simple adapter. The results of laser distance sensor can be
evaluated with Arduino. We are always looking ahead, hoping we can make every
measurement simple in life!

2. Lift the heat pipe evaporator on the foundation and level it. The horizontal error is not more than 50mm (the low point is at the drain outlet), and then welded with the base pre-embedded iron (the inlet side is the flue gas inlet).
3. The flue gas inlet of the heat pipe evaporator and the inlet of the flue are connected by pipeline (the pipe diameter matches the diameter of the flue gas hood flange of the heat pipe evaporator), and the inlet connection of the outlet and the draft fan (the diameter of the pipe diameter and the induced draft fan) The size is consistent), the outlet of the induced draft fan is connected to the kiln flue.
Note: A simple ram should be installed at the inlet of the heat pipe evaporator and at the exit of the draft fan. A ram should also be installed at the main flue of the kiln between the two slabs.
4. Before installing various valves on the steam drum, check whether the valve is defective and whether the starting is flexible. The safety valve should go to the technical supervision department to check the pressure value (the safety valve discharge pressure should be greater than the working pressure, less than the design pressure, and the specific value should be carried out according to the standard).
5. The orientation of the valve port of the safety valve and the vent valve should be set on the back of the operation area.
6. Connect water, steam, and sewage lines as required, and check for leaks.
7. Install the water level gauge as required. The water level gauge should be cleaned before installation to achieve brightness, clarity and smoothness. Install the pressure gauge as required, and correct the pressure gauge for flexibility before installation.
8. The installation of various pipeline valves is completed and the water pressure test is carried out. Before pressing, it should be cleaned to avoid debris and dirt. When the water pressure hits the design pressure, hold it for 30 minutes and check for leaks everywhere. After the leak-free point, the pressure is reduced to the working pressure. Under this pressure, the pressure is maintained for 4 hours. At the pressure holding time, the pressure can be reduced by less than one pressure, and the pressure is released and the water is discharged. Then add soft water to the water level gauge between 1/2 and 2/3 as required.
9. Check the induced draft fan, whether the motor is filled with lubricating oil, whether the operation is normal, whether there is noise or vibration, and if there is any shutdown, it is excluded. Check if the motor starting appliance is normal, otherwise it will be excluded.
10. When everything is normal, proceed as follows: first open the ram at the exit of the induced draft fan, start the induced draft fan, open the ram at the inlet of the heat pipe evaporator, and gradually lower the sluice of the flue. Pressure fluctuations to determine the extent to which the shutter is lowered). The flue gas is passed through the heat pipe evaporator, and the heat in the flue gas is absorbed by the heat pipe. The heat pipe heats the soft water in the steam drum by the principle of phase change heat transfer, and evaporates to generate steam for production and daily use.
11. Regularly remove ash, according to the instruction manual.
12. The heat pipe evaporator to the technical supervision department shall be registered according to the pressure vessel.
How to install RBL series heat pipe evaporator
1. Prefabrication of the foundation at a determined location, the basic dimensions are based on the size of the paper provided by the supplier. The thickness of the foundation is determined according to local geological conditions (generally, the thickness is about 150 to 200 mm).
