Short construction period? Hurry? Again busy, every day before starting, do not forget to carry on the whole view of the mixing pump! Preventive inspection can reduce the failure rate of the machine and ensure the safety of the construction. Problems by early detection and early processing will be good. We will be specific to discuss about the whole process of concrete mixer pump inspection:
1. Body view
1.1 The screen on the hopper should be placed smoothly.
1.2 It is necessary to put the protective cover of the pump chain in place.
1.3 It is necessary to close and lock the water tank cover plate.
1.4 The water tank should be filled with cold tap water or other fresh water. Remember: the injection of seawater or other salt water can avoid chrome layer corrosion of main cylinder piston rod and cylinder transport!
1.5 Pay attention to: the concrete mixer pump track should be fixed, and the lower end contact with the ground, no suspension.
1.6 The hopper climbing safety positioning bolt wheel has been pulled out.
2. Electrical system view
1.1 The main switch of the power supply shall be in the off position.
1.2 The control of the switch panel should be in vacancy; “remote control / control knob switch should be in the” control “range.
1.3 All electrical components, joints and wires should not be broken or loose.
1.4 The electrical box is closed and can not be opened during operation.
1.5 External high voltage power supply should ensure safety and reliability. Cable, wiring number one, protection is outstanding.
3. Hydraulic system view
3.1 Check the liquid level indicator, indicator level should be in 2/3 above, the lack of need to add oil, hydraulic oil, new products to meet the application requirements, must not have water or other liquid mixing, filling before filtration.
3.2 View grease bucket, grease should be about 2/3 of the barrel volume, if the need for filling.
3.3 Make sure that the control rod of the mixing valve and the multi leg valve of the concrete mixer pump is in the middle position.
3.4 Ensure the hose and steel pipe joint do not leak oil or oil leakage. If oil or oil spills, tighten.
