Recently, when I was helping a friend repair an excavator, I had my first close contact with the buzzing hydraulic motor. The mechanic kept saying to me while screwing in the screws: "This thing looks simple, but there is a lot of knowledge in it!" Today, let's talk about what is so special about hydraulic motors.
First of all, we have to talk about its "strongman" attribute. Last time I saw a concrete mixer driven by a hydraulic motor on a construction site, it was mixing two tons of concrete like dough, with an absurd amount of strength. The mechanic said that this is because the hydraulic system can easily generate high pressure, which is much greater than the torque of ordinary motors, and is particularly suitable for work that requires great strength.
Another particularly practical feature is speed regulation. I remember when I visited the factory, the assembly line controlled by the hydraulic motor could adjust the speed at any time according to the product requirements. When it was slow, it was like a snail crawling, and when it was fast, it was like a cheat. This stepless speed change function makes many precision operations particularly flexible.
However, hydraulic motors are not perfect. Once I saw a maintenance worker changing hydraulic oil at a mine, and his hands were covered with oil. The master complained that this thing has high environmental requirements, the oil must be changed regularly, and the pipeline must be leak-proof. If you don't pay attention, it will easily cause problems. But then again, the new intelligent hydraulic motor can automatically monitor oil pressure and temperature.
What surprised me most was its "reversal" ability. Ordinary motors can only rotate forward, but hydraulic motors can easily switch between forward and reverse. Last time I saw a crane controlled by a hydraulic motor at the dock, the up and down switching was particularly smooth. The operator said that this function increased their efficiency by at least 30%.
The hydraulic motor is like a low-key and powerful one. It may look inconspicuous on the outside, but it can always be of great use at critical moments. Next time you see those oily metal lumps in construction machinery, don't underestimate them!
The above is a popular interpretation of the characteristics of hydraulic motors written according to your requirements, using life scenes to bring out the technical characteristics. If you need to add specific technical parameters or adjust the expression angle, you can tell me at any time.
