Into the winter, most of the areas have entered the cold weather, this is a severe test of our concrete batching plant. So, in order to ensure the normal operation of concrete batching plant, it is necessary to carry out maintenance of concrete batching plant. The following is a detailed maintenance steps:

1 Condensate discharge

The condensed water discharge involves the whole pneumatic system, from the air compressor, air tank, piping system and air filter and automatic drainage device etc.. At the end of the operation should be discharged all over the water, in case the night temperature is below zero, resulting in condensation of water ice. Due to the temperature drop in the pipeline at night, will further precipitation of condensate, so the pneumatic device in the daily operation of the condensate should also be discharged.

2 Check the lubricating oil

A. In the pneumatic device operation should be whether the oil drop test oil mist quantity to meet the requirements, color is normal, the oil should not be mixed with dust and water etc..

B. Oil mist is the best one to fill the oil once a week: oil to pay attention to the amount of oil to reduce the situation. If the fuel consumption is too small, should adjust the amount of oil drops; the adjusted amount of oil is still little or no drop of oil, oil mist device should check whether the import and export of anti loaded, pipeline is blocked. To understand the content of lubricating oil is appropriate, its method is a clean white paper placed near the outlet valve of the valve, in three to four cycles, if only white light spots, show good lubrication, suitable for oil mist content.

3 Air compressor maintenance

A. Leak check to see if there is a leak.

B. Motor drive belt is loose, aging.

C. Pays special attention to supplement air compressor crankcase oil, oil oil sight glass shall not be less than the lower limit, and according to the air compressor nameplate to supplement or replace the winter oil with viscosity.

The maintenance of concrete batching plant in winter is a way to improve the production efficiency.
