The cold climate and environmental conditions pose a serious challenge to the use of our mixing plant products. In order to make the mixing plant work smoothly under the harsh climate conditions, we need to master some essential knowledge of winter maintenance of the products.

Water supply system maintenance instructions

1. 1、The water pump should be lubricated regularly as required.
2. 2、When the water pump is not used for a long time, the water inside the pipe should be discharged cleanly, if the shut-off valve is installed, special attention should be paid to emptying the water at the shut-off valve.
3. 3、winter use need to ensure the normal flow of water in the pipe, in order to prevent freezing can increase the insulation pipeline.
4. 4、regularly check the joints of the water supply pipeline, because the joints are prone to accumulate water.
5. 5、If the pump is stuck in the blade due to ice, please immediately turn off the pump power, use hot water to pour the pump shell until the motor shaft can move freely, do not forcibly open the pump to avoid damage to the parts.

Air supply system maintenance instructions

1.Condensate discharge.

Condensate discharge involves the whole pneumatic system, from air compressor, air tank, piping system and air filter and automatic drain. At the end of operation, condensate should be discharged from all places to prevent condensate from freezing at night when the temperature is below zero. As the temperature inside the pipeline drops at night, it will further precipitate condensate, so the pneumatic device should also discharge the condensate before the daily operation, pay attention to check whether the automatic drainer is working properly and the water cup should not store too much water.

Second, check the lubricant.

1. 1, in the operation of the pneumatic device, should check whether the amount of oil dripping from the oil atomizer meets the requirements, whether the oil color is normal, that is, the oil should not be mixed with dust and water, etc..
2. 2, the oil atomizer is best to replenish oil once a week: when replenishing oil, pay attention to the reduction of oil volume. If the oil consumption is too little, the amount of oil dripping should be readjusted; if the adjusted oil quantity is still little or no oil dripping, the oil atomizer should be checked whether the import and export are installed backwards and whether the pipes are blocked. To understand whether the amount of lubricating oil contained is moderate, the method is to put a clean white paper near the exhaust port of the reversing valve, the valve after working for three to four cycles, if there are only very light spots on the white paper, it shows that the lubrication is good and the oil mist content is suitable.

Third, the maintenance of air compressor.

1. 1.air leakage check to see if there is any air leakage.
2. 2.whether the motor triangle drive belt is loose and aging.
3. 3.Pay special attention to the replenishment of oil in the crankcase of the air compressor, the oil must not be lower than the lower limit of the sight glass, and replenish or replace the oil according to the nameplate of the air compressor that meets the viscosity for winter use.
