Construction irrigation concrete, pumping active, proper process, mastery; Preparation, pumping, cooperation, closing work, step by step, often successful. ready: Check to work, the whole machine intact, mixing hopper, foreign body emptying; Inventory tools, according to chapter refueling, the main oil unloading, electric door opened. Standby operation, careful observation, clear movements, key lubrication; Shutdown power, unloading handling, warning safety, waiting to start. Pumping: Guide cloth tube, be sure to kiss, pump tube connected, not plugging loose; Level with the right, a matter of fact, pump water slurry, pulp thick easy to pass. Uniform command, failed to pass avoidance, slow steady, pumping smooth; Stop pump timely, before and after the convergence, taking the time to check, be prepared. Cooperation: Irrigation construction, pumping center, echoes before and after blocking; Do not block fast, do not panic only pass, see material pump, pump in all. Case of no urgency, clear thinking, find out the reason, clever clears up; Elbow easy to block, cone pipe difficult, shut down too long, good vibration. Leakage separation, fastening pipe card, stop pump sabotage, timely anti-pumping; Pipeline is too long, to be fixed, broken pipe, pump back pumping. Broken tube connected, timely exhaust, safe operation, should not be stormed; Pump is dead, people need well-informed, full knowledge, everything is easy. knock off: Pumping is completed, did not forget the pump, pipe cleaning, operation stress; Disconnect the pump port, flushing equipment, piston refueling, lubrication open up. Repeatedly check, stop unloading, fill in the form realistic, shut down and shut down; Pumping method, from practice, promotion should be, improve and improve.
