Concrete pump daily maintenance tips

Concrete pump truck working environment is very bad, regular and proper maintenance is very important to ensure the efficiency and reliability of the equipment, as well as long working life and so on. In order to ensure the normal operation of equipment, not mistakenly construction, require the operator in the construction before the construction of ground inspection, ground maintenance. Concrete pump daily maintenance and inspection Check the hydraulic oil level, remain in the oil level more than 3/4, or should be filled with the same brand of clean hydraulic oil, the recommended filtering precision 20ude filter cleaning hydraulic oil. Check the quality of the oil: Shut down, after 30 minutes, with a clean cup then 0.5L oil, such as oil highly contaminated or emulsified, or stand for a few hours, the bottom of the precipitate, should immediately replace the oil. Remove the water tank cover, check the concrete piston should be sealed well, no mortar infiltration tank. Check the cutting ring and the lens plate gap. After each use is completed, thoroughly cleaned, check the condition of the wear parts, when the glasses and the cutting ring between the local clearance greater than 1mm, should be adjusted. Should be adjusted gap; when the gap is greater than 2MM, it is recommended to replace the cutting ring. Check the lubrication system work, S tube arm bearing position, bearing position lubrication bearings such as lubrication points overflow. Manual lubrication point Each class should be injected grease, see product lubrication signs. Check the distribution valve swing, mixing device is positive, reverse normal operation. (Power on check, check off after shutdown, and then other items of maintenance work). Check the cooler outside, if dirt immediately cleaned, otherwise easily lead to oil temperature overheating. Check hydraulic filter vacuum gauge is only, should be in the green area (vacuum is strictly prohibited more than 0.04Mpa). General suction vacuum should be less than 0.02Mpa. Back to the oil pressure vacuum value should be less than 0.35Mpa. Tap way to check the degree of wear of concrete pipe, pipe joints to check whether the production of a good seal. Check the hydraulic system for oil leakage, oil leakage, leakage phenomenon. (Editor: Li Juan)
