Device function

1. Learn the measurement method of direct tube friction resistance △ PF, direct tube friction coefficient λ.

2. Master the relationship between the friction coefficient and Renault number re -Rennie in different flows and its changes. Verify the relationship curve of λ and RE in the turbulence, transition, and turbulence areas.

3. Determine the local resistance coefficient when the fluid flows through the valve in turbulence.

4. Precisely measure local resistance with a four -point pressure measurement method.

5. Integrated control, high -stable data transmission, hardware encryption.

Specification (L × W × H): 1500 × 720 × 800mm

Technical structure parameters:

The overall steel plate structure is adopted: configure the drawing desktop, the computer display platform, the m--n cabinet, tool drawing and keyboard pumping, etc.;

Left and right desktop substrate: The m--n desktop on the left adopts the standard No. 1 (900 × 600 × 20mm thick) Northeast beylum thick drawing special board. The desktop flat, synchronous control adjustment adjustment tilt 0-70 °. Turn the handle with the hand shake by the side, which is convenient and reliable.

3) Multiple storage space: the left and right configuration tools of the lower part of the desktop and the keyboard pump to meet the needs of d--ly teaching drawings and computer operations; the open m--n cabinet on the right side of the desktop body is convenient for placing the host;

4) Stability adjustment foot pads: The bottom is used to adjust the screw foot pad or universal wheel with plastic wood levels at the bottom. It can be anti -slip and noise, and has the regulatory function to ensure the stability of the desktop and the strong structure.

M--n material specifications and surface treatment:

1) Drawing desktop brackets use high -quality torque pipe materials (30 × 60 × 1.0mm) and steel plate materials above 0.8mm; all desktop structure or component steel are national standard products, and the welding parts must be carbon dioxide protection welding process. Welded, the solder joints are firm, smooth, and beautiful, with no bubbles, burrs and leakage welding, and fake welding. They have the resistance to wear resistance and scratch. Oil removal, rust removal, and pickled phosphorus treatment to ensure that no plastic peeling and anti -rust are occurred.

2) The desktop substrate uses the northeast beef wood thickened professional drawing board (900 × 600 × 20mm thick), which has the performance of durable and difficult to deform. The melamine desktop tablet is formed with high frequency thermal pressure at one time. The n--ling force is strong, it is not easy to expand, it is not easy to deform, and it is firm and durable. The edge of the high -quality PVC plus imported thermal solution fully automatic mechanical border seal is adopted by 1.5mm. The edges are neat and smooth, and the layers are clear.
