General knowledge of excavator Mini Excavator Parts
In fact, there are a lot of stress in the use of excavators. As a good assistant to excavators, what should we pay attention to when using excavators? Let’s have a look.
1. correct parking posture
In case of rain, snow and thunder, it is recommended to stop the machine in this way to better protect the excavator oil cylinder. When the excavator does not work for a long time, or is shut down for holidays in the Spring Festival, the excavator must be stopped in this way, so that all the oil cylinders can be soaked in the hydraulic oil, so that the oil film can be spread on the oil cylinder, which greatly protects the service life of the oil cylinder and will not be corroded.
After the completion of each day, the jib is lowered vertically at nearly 90 degrees, the bucket cylinder is retracted, and the bucket teeth are parked downward to protect the cylinder piston rod.
2. pay attention to the idler position
When going uphill, make sure that the guide wheel is in front and the drive wheel is in the back, extend the forearm, open the bucket, and keep the bucket 20 cm away from the ground for operation and drive slowly. At the same time, it should be noted that the slewing action should be avoided during the uphill process to prevent danger. When going downhill, the drive wheel is in front and the guide wheel is in the back. Extend the jib forward to make the bucket teeth of the bucket work downward 20 cm from the ground, and slowly and vertically go downhill.
3. how to exhaust air from hand pump
Open the side door of the hydraulic pump, remove the dust cover of the diesel filter element, loosen the vent bolt on the diesel filter element base, press the hand pump until the air in the diesel system is exhausted, and tighten the vent bolt.
4. right / wrong posture for crushing
Wrong operation 1: during crushing operation, too small thrust of the big and small arms to the hammer will cause too large vibration of the crushing hammer body and the big and small arms, resulting in its failure.
Error operation 2: during crushing operation, the large and small arms give too much thrust to the hammer, and the crushed object will cause the hammer body and the large and small arms to collide at the moment of being crushed, resulting in its failure.
Wrong operation 3: the thrust direction of the big and small arms to the hammer is inconsistent, and the drill rod and bushing are always hard engaged during the strike, which not only aggravates the wear, but also makes the drill rod easy to break.
The correct operation is as follows: the thrust direction of the big arm and the small arm to the hammer is consistent with the longitudinal direction of the drill rod and perpendicular to the hit object.
