Principle one
1. The power of the air compressor is taken out of the gearbox and the air compressor starts to compress the air;
2. After the air is compressed by the air compressor, it enters the air chamber through the check valve and the air intake pipe, and enters the charging warehouse through the fluidized bed; when the air speed reaches a certain value, the cement in the tank
Begin streaming. When the pressure reaches 0.18 MPa, the unloading dish valve is opened, and the fluidized cement material is discharged through the discharge pipe under the influence of the difference in the pressure inside and outside the tank.
3, tank pressure can be displayed by the pressure gauge (10).
4. When the pressure is greater than 0.22 MP, the safety valve opens automatically, keeping the pressure in the chamber below 0.22 MPa.
Principle two
1. Compressed air is connected by an external air source interface, enters the air chamber through the check valve and the air intake pipe, and enters the charging warehouse through the fluidized bed; when the airflow speed reaches a certain value,
The cement in the tank began to fluidize. When the pressure reaches 0.18 MPa, the unloading dish valve is opened, and the fluidized cement material is discharged through the discharge pipe under the influence of the difference in the pressure inside and outside the tank.
2, the pressure can be displayed by the pressure gauge (10).
3. When the pressure is greater than 0.22 MP, the safety valve opens automatically, keeping the pressure in the chamber below 0.22 MP.
Subframe
The sub-frame is formed by welding two riveted beams with L-shaped cross-sections and beams with the same cross-section. The structure is shown in the following figure:
a、Bulk cement truck operation essentials
(I) Loading:
1. Before the charge, one feed inlet is opened, and the other feed inlet is closed;
2. Close the discharge disc valve and external air source interface;
3, open the exhaust valve;
4. Select one of the bins and close the bin's feed inlet after loading one bin;
5, open another warehouse feed inlet, loading;
6. After the two bins are charged, close the exhaust valve and the feed inlet;
7. Tighten the feed inlet.
(b) Discharging:
a, unloading steps
1. Before discharge, check whether the unloading disc valve, the external air source interface, the exhaust valve, and the two inlets are closed and tightened. If they are not tightened, tighten them first to prevent air leakage.
2. Start the engine and shift the transmission to neutral. At the same time, depress the clutch pedal to completely separate the transmission from the engine.
3, open the power take-off solenoid valve switch, while slowly releasing the clutch pedal, so that the air compressor rotation;
4, adjust the operating mechanism of the operating handle, the air compressor speed adjusted to 900r/min or so, and stabilized;
5, when the pressure reaches 0.18MPa, first open the blowing pipe, and then open the front and rear warehouse discharge disc valve, start unloading, after which the air compressor pointer will stabilize a certain value;
6, when the pressure dropped to 0.04Mpa, after the warehouse has been unloaded, close the blowpipe, after opening and closing the disc valve a few times, and then the rear compartment valve and the rear compartment intake valve is closed, that is, only the front warehouse discharge ,
After that, the pressure will rise and stabilize to a certain value;
7. When the pressure of the barometer reaches 0 MPa, the unloading is completed, the air compressor is turned off (closing the power switch), and the unloading disc valve is closed.
b. Precautions
1. When loading, care should be taken not to fill the powder tank. Part of the space should be reserved for the expansion of the powder.
2. When loading, avoid mixing the impurities into the tank, so that the discharge tube is blocked, affecting the discharge speed and remaining rate;
3. When the unloading operation is performed in step 3, if the air compressor has abnormal noise, the clutch pedal should be depressed, the engine shut off, and the power takeoff solenoid valve switch closed.
Until the troubleshooting, can work;
4. During step 6 of discharge operation, special attention should be paid to changes in the pressure gauge. Operators cannot leave the site to avoid excessive pressure.
5, daily should keep the tank dry, avoid powder agglomeration;
6. When the vehicle is being repaired, it is necessary to prevent the parts from falling and avoid knocking, so as to prevent the parts from being damaged, deformed, bumped, scratched, etc. The parts must be cleaned carefully when they are loaded;
7. When the air compressor is working, the air compressor side should avoid standing people;
8. When speeding up, do not add too much pressure on the accelerator and use even force.
9, suction mouth and bottom distance can be adjusted, generally 30 ~ 50mm.
10, remember that you can not use the external air source exhaust.
11. When the compressor is stopped for other reasons due to other reasons during the construction of the compressor, the front and rear compartments should be closed and the external air source should be opened.
After a while, turn off the external air supply and open the balloon valve in the front and rear compartments.
12. Special attention: After the first unloading, it is necessary to check the fulcrum bolts and U-bolts, and fasten the bolts.
Afterwards, each bolt should be inspected on a regular basis. If loosening is found, tighten it.
c. Handling of emergencies
1. When air pressure is built up, when the pressure inside the tank is too high and the safety valve opens, the exhaust valve can be opened and depressurized;
2. When the tank is filled with water, the water should be discharged in time through the two drain valves at the bottom of the tank. If the fluidized bed canvas gets wet,
The fluidized bed canvas should be replaced in time to avoid cement clumping on it;
3. During the unloading process, if there are other abnormalities that require terminating the unloading, the unloading dish valve may be closed first, and then the pressure in the fluidization chamber may be unloaded by opening the exhaust valve.
