Electric hydraulic block brakes are mainly used for mechanical braking of driving devices in lifting, transportation, metallurgy, mines, ports, and construction machinery. They have the advantages of smooth braking, safety and reliability, convenient maintenance, low power consumption, long service life, and no noise.
Usage conditions
Environmental temperature: -20 ℃~+50% using DB-25 hydraulic oil: below -20 ℃ using YH-10 aviation hydraulic oil, air relative humidity not exceeding 90%, generally used for three-phase AC power supply, 50HZ, 380V, sea level in accordance with GB755-87 standard
The use of electric hydraulic block brakes may result in the pushrod of the thruster not being able to be pushed up and the brake not being able to release normally. This article is based on the normally closed electric hydraulic brake and analyzes the reasons for the brake to not loosen from the aspects of design method and structural form, and proposes improvement measures.
