Running direction and leakage protection of polyurethane mixing machine
Aug 23, 2018

The polyurethane mixing machine should be placed in a flat position during use. When operating, the front and rear axles are mainly padded with square wood, so that the tires can be placed overhead so as not to move when starting. The mixer should be equipped with secondary leakage protection. After the power is turned on before going to work, it must be carefully inspected. It can only be used after passing the empty car test. During the test run, it should be checked whether the speed of the mixing drum is suitable. Under normal circumstances, the speed of the empty vehicle (after loading) is slightly faster than 2~3 turns. If there is a large difference, the ratio of the moving wheel to the transmission wheel should be adjusted.

The direction of rotation of the mixing bowl of the polyurethane mixer should be in accordance with the direction indicated by the arrow. If it is not true, the motor wiring should be corrected. Check whether the transmission clutch and brake are flexible and reliable, whether the wire rope is damaged, whether the track pulley is good, the surrounding is unobstructed and the lubrication of each part.

After the polyurethane mixing machine is turned on, it is necessary to pay attention to whether the operation of the components of the mixer is normal. When the machine is stopped, it is necessary to check whether the mixer blades are bent or not, and whether the screws are knocked down or loose. When the concrete is stirred or expected to stop for more than 1h, in addition to the remaining material, the stone and water are poured into the barrel, turned on, and the mortar stuck on the barrel is washed out and completely discharged.
