The new regulations began to implement the window is strictly prohibited reflective stickers
The tangential pump is divided into two types: vertical and horizontal. Its biggest feature is that the flow-head curve is very flat, that is, in the full flow range, the head does not change much, and when the pump flow changes from zero to the required maximum flow range, its The head change is within 5%, and there is no overpressure at low flow or zero flow, thus avoiding the phenomenon that the ordinary Centrifugal Pump is overpressured at medium and small flow and cannot supply water at large flow at the fire scene, greatly improving the fire extinguishing efficiency and firefighters. safety and reliability.

Window glass visor film
The new "Technical conditions for the safe operation of motor vehicles" is implemented today. The new national standard stipulates that the visible light transmittance of the front windshield glass and the glass other than the wind window should be greater than or equal to 70% for the driver's view area (where the driver used to observe the rearview mirror). All glass windows must not be mirrored with reflective visors. Visible light transmittance of all windows of road passenger cars, tourist buses and school buses shall be greater than or equal to 50%, and no colored paper or insulation paper with opacity and any specular reflective material shall be posted.
The motor of the thread tangent pump is an ordinary motor and does not need to be changed. It effectively solves the pressure fluctuation when the flow rate changes in the water supply process, and the problem of serious overpressure when the flow rate is small. Compared with the parallel operation of multiple pumps, it can reduce the number of pumps, reduce the floor space, and is easy to operate and manage; compared with the variable frequency speed control pump, it can save investment, facilitate management, and has many advantages. It is a more complete solution to overpressure. Method.
