3. Structure and Performance
①Image 1 indicates:
Vibrating part is made up of glass board(1),scale division board(2),3
clips(3),circle plate(4),pole(6). Gross weight is 3.45±0.01Kg
②Transmission part( see image 1)
After going through the power source, electric machine rotates with cam by 60 rotations in one second. Other rotational part rotates by 1 time in one second.
③Self-Stop Part (See Image 2)
In the left side of cam main axle nose is loaded with the drive gear (15) to mesh with another driven, Two gears end surfaces are loaded with a hitting block,When cam rotates 30 times, two hitting block meet,Through hanging foot, the axis and horizontal pole (17) to the limit switch (16) the severance of action electric motor electric current, achieves self-stop request.
④ Electricity schematic drawing (Image 2), Electricity Installment drawing(Image 1)
Resistance, Electric capacity “c1”,”c2” and device J(12) are installed on the machine frame Ledger wall(5). The buttons TA(13) ,QA(14)is installed on the cover (11) board. The limit switch (15) is installed on the front box cover. 3-cores plug connects with power 200V. Press green button QA(14), J（12）is powerful，The permanent magnetism slow-speed motor starts to revolve, After Inspiring part inspires 30 times, Automatically cut power with the limit switch and stop working. Continue working in the same method. Press red button TA（13）to stop it.
⑤Setup Requirement
The machine installes horizon on the firm base foundation and is fixed with three foot bolts
4. Experimental material and Test Condition
GB177-77
5. Flows Determination
①Material and Quantity
Cement : 300g
Standard Sand:750g
Water: According to request
Attention：Reference GB177－77
②Manufacture Cement Sand
Reference GB177－77 15th list
6. Note: Measuring board sees image 3
7. Flows value scope
In November, 1981 the cement rubber granulated substance flowed according to the building maintenance section institute cement physics room the experimental study material to have as follows stipulated that:
①In five big cement other four kind of cement had all stipulated flows besides the silicate .
②Stipulated content as follows:
These four kinds of cement categories respectively are the pulverized coal ash cement, the puzzolana cement and common cement mixed with the pulverized coal ash and the volcano gray matter and the slag cement. They conform to GB197-77. If value determined is lower than 125. need to add water to cause the cement sand flows to achieve in 125-135 millimeter scope. That is needed water volume.
8. Device Maintain
Clean up the glass board surface with soft cloth. And add some oil on the machinery parts to avoid rusty
