Pre-operation preparation of vacuum kneader


The vacuum kneading machine mainly consists of six parts: kneading part, frame part, hydraulic system, transmission system, vacuum system and electronic control system. The kneading part consists of cylinder block, slurry shaft, wallboard, cylinder head, etc. The hydraulic system operates two small cylinders and two large cylinders by a hydraulic station to complete the functions of opening and closing large caps and turning stirring cylinders. The system design pressure is 7.0 Mpa. The electronic control system has manual and automatic electronic control system, which is selected and required by users at will. It is convenient and reliable to operate. The transmission system consists of motor, reducer and gear, and matching motor according to kneader type. In the process of transmission, the speed can be synchronized by the motor, through the elastic coupling to the reducer, the output device can drive the fast slurry to achieve the specified speed, and also can be adjusted by the frequency converter.

Vacuum kneader preparation before operation:

1. After the machine is installed, clean, decontaminate and wipe the rust-proof grease first. Check all lubrication points and inject lubricating oil (grease).

2. Check the tension of the triangle belt before driving, and move the motor to the appropriate position by adjusting the bolts.

3. Check whether the fastener is loose, whether the steam pipeline is leaking, whether the circuit and electrical equipment are safe. Electric heating kneader must have grounding device.

4. Clean up the kneading room before testing. Make 10 to 15 minutes of empty operation, confirm the machine is running normally before feeding production. Generally, the noise of new gear (including reducer) is larger in initial use, and it will decrease naturally when it is running in and out for a period of time.

5. When using steam heating, safety valves and pressure gauges shall be installed at the intake pipeline. The steam pressure shall not exceed the requirements of the mixing cylinder indicated by the label.

6. When kneading propellers, the use of reversal should be reduced.
