When concrete pumping construction after 50 hours or general construction of concrete between 1500 and 2,500 cubic meters, during this period needs to be maintained for the first time, after the concrete pump is to ensure that function properly, without loss of life, correct construction, maintenance is very important for the first time.

Maintenance maintenance the same as routine maintenance for the first time, require maintenance projects are:

1, check the hydraulic oil level, oil, check oil, which itself should be on yellow transparent, no emulsification or turbid, or should be replaced.

2, fill it up with grease, fill it up with water the water tank.

3, check the concrete piston, should seal well, no mortars into the water tank.

4, check the clearance of the cutting ring, glasses case, maximum 2mm.

5, check the lubrication system is working, you should see the progressive oil separator indicates the rod back and forth action. S tube swing arm bearing positions, stirring shaft bearing lubrication oil overflow.

6, check all electrical components for proper functionality.

7, check the distribution valve, Stirrers rotating correctly.

8, check the cooler outside of Po dirt cleaned immediately, otherwise easily lead to oil overheating.

9, in a striking manner to check the concrete pipe wear, check the pipe is sealed well.

10, check the hydraulic system for leakage, oil leakage.

11, check all screw connections, ensure that it is securely connected.

12, check the tank connection bolts for connecting rod in the middle is firm.

13, check the vacuum gauge and filter element.

Above is the construction work 50 hours later first maintenance of concrete pump machine, if you have questions, please feel free to consult.
