What Role Do Hydraulic Cylinders Play In Tunnel Mucking Machine Work?

The hydraulic cylinder of the slag scraper belongs to the actuator at the end of the hydraulic system, and it is also the power support for the action of the Tunnel Mucking Machine when scraping materials. Therefore, the hydraulic cylinder of the Tunnel Mucking Machine is very important, which directly affects its quality. performance of the hydraulic system. So how to judge the quality of cylinder products?

The buffering effect of the hydraulic cylinder of the crawler Tunnel Mucking Machine: a buffer mechanism is set at the end of the Mucking Machine hydraulic cylinder stroke, which can decelerate the piston component to near zero when it reaches the end of the stroke, thereby reducing the pressure of the piston and hydraulic pressure caused by the inertial force and hydraulic pressure of the piston component. Mechanical impact between end caps, thereby reducing noise and preventing damage to TBM Mucking Machine hydraulic cylinders. The general requirements of the buffer mechanism are: the buffer mechanism should be able to absorb a large kinetic energy with a short buffer stroke. During the buffering process, the pressure change in the buffer chamber is relatively gentle, and the peak pressure is less than 1.5 times the rated pressure of the Mucking Machine hydraulic cylinder. When the kinetic energy is converted into heat energy and the oil temperature rises, the maximum temperature of the oil should not exceed the allowable limit of the seal.

Internal leakage and external leakage of the hydraulic cylinder of the belt Tunnel Mucking Machine: Internal leakage refers to the leakage of hydraulic oil from the high pressure chamber to the low pressure chamber in the two chambers of the Mucking Machine hydraulic cylinder. The internal leakage of medium and high pressure double-acting hydraulic cylinders is regulated by quality classification. External leakage refers to the leakage of hydraulic oil from the cylinder piston rod or other places. The leakage of medium and high pressure double-acting Mucking Machine hydraulic cylinders and single-acting Mucking Machine hydraulic cylinders shall be regulated by quality classification. These two points are the key to judging the quality of the Mucking Machine hydraulic cylinder of the Tunnel Mucking Machine, and also an important guarantee for the mechanical action of the hydraulic cylinder when the Tunnel Mucking Machine is working.
