Gebin.com manufacturer introduces the application of ecological green grid in spring farmland water conservancy construction
Gebin network ecological green grid processing process 1. Raw material selection (wire rod) 2. Cold drawing, galvanizing / plastic coating 3. Heavy-duty hexagonal net machine weaving 4. Manual cutting, nesting 5. Box body composition 6. Folding and packaging, transportation ecological green grid assembly process:
1. Stagger the cage in place to avoid longitudinal through seams.
2. Raise the four sides of the box and lock the adjacent edges with the binding line. When the lock is tied, tie the binding line around the two overlapping frames (when stitching the edges) or the double twisted edges of the frame and the cage ( When sewing the grille) Spiral tightly to avoid heavy galvanizing damage, the pitch is not more than 50 mm.
3. When installing the gabion cage on the completed bottom layer, apply the binding line to the bottom cage along the lower frame of the newly installed cage, and the adjacent layers of the same layer are also tied to each other by the binding line. It is integrated into one.
4. In the construction of the same horizontal layer of a unit project, the gravel shall be filled after all the stone cage nets are in place. In order to prevent the deformation of the cage, the height difference of the adjacent two tanks should not exceed 35 cm.
The manufacturer of Gebin.com recommends that the size of the ecological grid be reasonably matched to achieve the voidage of the design requirements and to ensure the straight shape of the gabion net.

Chemical Industry Mass Flow Meter
Sealand is a professional supplier of Chemical Mass Flow Meter, Chemical Mass Flowmeter, Chemical Flowmeter, Chemical Flow Meter, Chemical Coriolis Meter, ATEX, IECEx & CE approved.
The meter can work with a pulse receiver(Count). The connection is as follows. The resistance value is up to the cable length & the max. input pulse frequency of receiver. Current 10mA is suitable for most receivers; however, you can reduce the resistance value when the cable is long. The max. current could be 50mA. Please use the fixed frequency output function to check if the cable length & resistance value is suitable.
Please check following items before operation, and operate according to relevant rules.
a) If the meter is damaged during shipment and installation;
b) If the voltage is same as marked on nameplate;
c) If the fuse is correct;
d) If the meter is grounded properly.
e) If the Meter SN on the nameplate of sensor and transmitter are the same.
If everything is fine, please open all valves, make the pipeline full of liquid and then power on
the meter for warm-up for 20min before operation. Finally, conduct zero calibration after first
start, and shall do it again if the meter is moved to another site.
Preparation for zero calibration:
a) Power on the meter for approximately 20min for warm-up;
b) Run the process fluid through the sensor until the sensor temperature reaches the normal
process operating temperature.
c) Close the shutoff valve downstream from the sensor.
d) Ensure that the sensor is filled with fluid and the process flow has completely stopped.
