1. After creating the concrete pump, make complete study of concrete pump along with the examination content includes the next aspects: find out if the oil quantity of hydraulic oil is inside the specified range, find out if the text within the hydraulic rubber hose connector and pipe clamp permanent chair is loose otherwise, check whether there's oil leakage phenomenon, check whether you will find break line and off-line for electric components cables, find out if the contact bolts losing and check whether you will find materials and harmful pollutants within the hopper.Henan Daswell Machinery is a professional manufacturer of mining machine for almost 30 years in China.

Study of electrical appliance. To begin with, think about the present of construction sites whether it is (380±10％)V and concrete pump needs to be fitted with special control switch along with the specs of people cables must be will i think the the primary cables of pump machine and they're associated with ground well. Then perform following examination: (1). Turn on the switch of control line along with the energy indicator light will most likely perform. At the same time, the prrr-rrrglable controller PLC module connects with electricity. Get sucked in in the indicator light across the PLC module (it may be classified into start, operation and problems) when beginning the system, when the operation indicator light is on along with the problems indicator light is off SICOMA Planetary Concrete Mixer, readily stored away typical and may operate normally. Other smart, pump machine doesn't work. Concrete Pump (2). Press the beginning button of electrical motor concrete mixers, check whether ac contactor of electrical motor whether or not this works based on techniques and check once the energy indicator light is on. (3). Press the moving button, anti-moving button diesel engine concrete mixer, pressure test button and mixing button correspondingly, find out if the prrr-rrrglable controller has input signal and output signal. 3. If all above aspects are normal, operators can begin the pump machine.
