2. Good sealing

In order to make the quality of the seal. there is an oil supplier on the end face of the mixing cylinder.

3. Stirring strong

The two output shafts of the reducer drive the two horizontally configured stirring shafts to rotate back at equal speed respectively through two pairs of open gears.

4. Easy operation

The electric control system adopts components with more functions. stable performance and easy to operate and use.

JS concrete mixer maintenance and maintenance

1. every shift to check whether the shaft end sealing cavity. distributor import and export and sealing pipeline is smooth. whether it is full of grease. whether there is enough lubricating oil (grease) for each lubrication point and reducer box body.

2. reducer box once put into use 50 hours. need to replace the lubricant. in future production. every 1000 hours or half a year also need to immediately replace the reducer box lubricant.

2. the concrete mixer should be implemented two leakage protection. before going to work after the power is connected. must be carefully checked. by the empty test run that qualified. before use. Test run should test the mixing cylinder speed is appropriate. in general. the empty speed than the car (after loading) slightly faster than 2 ~ 3 revolutions. such as the difference between more. should adjust the ratio of dynamic wheel and transmission wheel.

3. The direction of rotation of the mixing cylinder should be in line with the direction indicated by the arrow. if it does not match the reality. the motor wiring should be corrected.

4. Check whether the transmission clutch and brake are flexible and reliable. whether the steel wire rope is damaged. whether the track pulley is good. whether there are obstacles around and the lubrication of each part. etc.

5. After starting the machine. often pay attention to the normal operation of the concrete mixer components. When the machine is stopped. often check whether the concrete mixer blade is bent. whether the screws are knocked down or loosened.

6. when the concrete mixing is completed or expected to stop for more than 1 hour. in addition to the residual material out of the net. the application of stones and water into the shaking cylinder. turn on the rotation of the machine. the sticky mortar on the barrel rinsed clean after all unloaded. There should be no water in the barrel to avoid rusting of the barrel and blades.
