1. When the soybean is processed, the puffing chamber discharge port is not discharged.
Reason: too much feed in a short period of time, causing blockage of
Remedy: Reduce feed rate.
2, the soybean powder puffed out when processing soybeans, there are watercress
Reason: The raw material is not pulverized or the pulverization particle size is too large, and the sieve piece is leaked and damaged.
Remedy: Check the shredder and replace with a new one.
3, the temperature inside the expansion chamber does not reach the required rated temperature
Cause: The pressure ring ratio is too small or the amount of steam added is insufficient, the quenching temperature is too low, or the pressure ring or screw is worn.
Remedy: Change to a larger pressure ring or increase the quenching and tempering temperature. The temperature of the quenched and tempered material should be between 80 °C and 90 °C. Maintain the oil in the expansion chamber jacket: the first table temperature is 60 ° C, the second table temperature is 100 ° C, the third table temperature is 125 ° C, and the fourth table temperature is 145 ° C.
4. When processing powdery puffed material, it will not block or produce paste-like thinner.
Cause: The water supply and steam pressure are too small or too large, and the steam volume is too small.
Remedy: Adjust the water or steam pressure.
5, the output declines, can not reach the capacity
Cause: The tapered pressure ring or wear ring is worn, or the screw head is severely worn.
Remedy: Replace worn parts.
6, suddenly do not discharge during normal work
Reason: 1) Too much feed in a short time. 2) Foreign matter blocks the discharge hole.
Remedy: 1) Slow down the feeding speed. 2) Stop, disassemble and clean up.
7. Puffed particles are too large or too small.
Cause: The die end hole is too large or too small.
Remedy: Configure the appropriate size of the discharge die hole as required.
8. When the soybean is processed, the expanded bean powder is sprayed back from the feed port.
Reason: 1) Too much feed too fast. 2) The discharge is not smooth or blocked. 3) The screw head and pressure ring are not properly configured. 4) The puffing chamber is seriously worn.
Remedy: Control the feed rate and feed amount, and adjust the distance between the discharge screw plug and the shaft end tapered nail according to the fault 1 requirements; reassemble after inspection and replace the new expansion chamber.
9. The product is blocked before the discharge of the die hole.
Reasons: 1) The particle size of the raw material is too large relative to the die hole size. 2) The amount of water is insufficient, which makes the material flow. 3) The structure of the extrusion chamber is unreasonable. 4) The diameter of the pressure ring may be too large.
Remedy: 1) Smash to the appropriate fineness. 2) Water is added at the beginning of the product entering the expansion cylinder. 3) Arrange the pressure ring and the screw head in a reasonable manner. 4) Replace the pressure ring with a smaller diameter.
10, the product is poorly formed (suckling pig material)
Reasons: 1) The raw material formula is not appropriate. 2) The temperature is too high or too low during processing. 3) The amount of material entering is not constant (sudden or small). 4) The moisture content of the product is too high or too low. 5) Blade wear (poor cutting effect). 6) The particle size of the raw material is too large.
Remedy: 1) Change the original formula. 2) Adjust the quenching and tempering temperature and the amount of steam entering. 3) Adjust the tempering pulp to make the material evenly enter. 4) Reduce or increase the amount of water and steam added. 5) Replace the cutting blade. 6) The raw material is pulverized to a suitable particle size.
FAG Bearing
Does it look glossiness?Does it feel smooth?Does it make any noise?
A high quality Deep Groove Ball Bearing must be hypefine grinded with smooth surface, no burrs on the edges,running fast &noiseless, that is the feature of our products.
They have low friction and are optimized for low noise and low vibration which enables high rotational speeds.They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing
types.
