1, Chargement

1.1, Before open the manhole, Chargement, and check the inner tanker pressure is equal to atmospheric pressure, Chargement. the pressure gauge value is zero.

1.2, After open the manhole, Chargement, especially the tanker ever loaded powder material and was off duty for long time. Chargement, Chargement.

1.3, After material loaded, Chargement, Chargement, Chargement.

2, Chargement

2.1, Connect the discharge hose of tanker to the needed place, Chargement.

2.2, Close the discharge butterfly valve, outside air supply valve and the assistance air valve.

2.3, Start the engine of truck, Chargement, depress the clutch pedal, Chargement, puis relâchez lentement la pédale. After the compressor run smoothly, then accelerate to the rated speed and supply the pressed air to tanker.

2.4, When the pressure gauge value reaches to 196KPa, puis relâchez lentement la pédale. During the unloading period, puis relâchez lentement la pédale, that means the discharge pipe was blocked.

2.5, Control the gas pedal, keep the discharge pressure between 185 and 196KPa. The normal bulk cement discharge speed is 1.1mt/min. When the tanker is empty, the tanker’s pressure would be 9.8-19.6KPa, at this moment open the air assistance valve, make sure all the powder material in discharge pipe blew out.

2.6, Release gas pedal, depress the clutch pedal and disengage PTO, stop the compressor.

2.7, Open the relief valve of tanker, exhaust the remaining pressed air in tanker, make the inner pressure equal to atmospheric pressure.

2.8, When the unloading horizontal distance is over 5 meters or vertical height is over 15 mètres, after open the discharge butterfly valve, the assistance air valve would be open, so that dilute the density of powder material and raise the pumping height.

3, Daily maintenance

3.1, Often check the pressure gauge, if fail show the normal pressure, must be replaced at once.

3.2, Frequently inspect and adjust safety valve, make the safety valve work at the pressure of 180-200KPa.

3.3, Often check the air filter of compressor. puis relâchez lentement la pédale. La méthode de nettoyage utilise de l'air sous pression (puis relâchez lentement la pédale) souffler le filtre à air de l'intérieur vers l'extérieur. Si le compresseur a été utilisé dans un environnement très poussiéreux, la période de nettoyage doit être raccourcie. Après le nettoyage du filtre 5 fois ou très sale, alors il faut le remplacer par un neuf.

3.4, The engine oil of compressor need to be changed regularly, normalement tous les six mois
