Posted On: 06/07/2017 | Posted by: Haomei Concrete Pumps

Inspection and maintenance of  concrete pump electrical equipments:

1.Check whether the voltage of electric pump is normal; check the storage battery and circuit of diesel pump;

2.Check whether the instrument, indicating lamp and all the operating pieces work normally;

3.Operate in accordance with stipulated the sequence, avoid starting with load;

4.Keep cleanness and dryness of electrical equipments;

5.Protect the cable and remote control wire.

Inspection and maintenance of hydraulic system:

1.Ensure that the level, quality and temperature of oil in the oil tank meet the requirement;

2.Ensure that the oil pump, pressure of oil motor, flow, noise and temperature rising are in normal range;

3.All the valves, accumulators and pressure gauges should work well;

4.The connection of concrete mixer with pump hydraulic pipeline should be reliable without leakage.

Inspection and maintenance of water tank:

1.The water in the tank should be replenished in time, when the water consumption is too fast, check to find the reason and dispose it;

2.Keep the water clean. If the water is muddy or there is oil floating on the water surface, change the water in time; if the water pollution is serious, clean the water tank; the general water tank cleaning frequency is once per 5～8 shifts. If the water polluting speed is too fast, check to find the reason and dispose it;

3.Pay attention to heat preservation during cold seasons, or add 20I antifreeze solution to prevent the water tank being frozen.

Inspection and maintenance of cement pump machine hopper:

1.Clear the oversize aggregate or other sundries on the grid away at any time, don’t remove the grid arbitrarily;

2.Wash the cement paste that spills to the external of hopper in time;

3.Prevent the reinforcing steel bar and other foreign matters entering into the hopper; check the reason in time if the mixer shaft is blocked and eliminate the fault;

4.Lubricate the mixer bearing in time.

Inspection and maintenance of S pipe:

1.Wash the concrete splashed on the external of the valve box away by water in time;

2.Keep the valve window airtight, if there is water leakage, mortar leakage or air leakage, check and dispose it immediately; after opening the valve window, it is necessary to clean the sealing surface and seal ring and close it tightly;

3.Ensure that each lubricating point of distribution valve, and the bearing pedestals of big end and small end are lubricated.
