Development Trend of Industrial Electric Hydraulic Pushrod Brakes
With the development of equipment towards large-scale and ultra large-scale, as well as efficient automation, brakes are rapidly developing towards heavy-duty, multifunctional, intelligent, and maintenance free braking conditions. The overloading of braking conditions is to meet the matching braking requirements of large and ultra large heavy-duty mechanisms; Multi function mainly includes brake release interlocking function, manual release function, liner wear limit limit limit (interlocking) function, wear automatic compensation function, etc; Intelligence refers to the introduction of digital and computer technology into control systems; Maintenance-free refers to turning the manual adjustment function of the brake into an automatic adjustment function, while achieving high reliability of brake action and performance. In addition, achieving real-time maintenance of industrial brakes through remote monitoring is also an important development direction for brakes.
With the rapid development of lifting and loading and unloading machinery towards large-scale and ultra large-scale, specialized and efficient, as well as semi-automatic and automated directions, the application of safety brakes has also been rapidly developed. At present, safety brakes have been widely used in large-scale port specialized loading and unloading machinery, and large-scale specialized lifting equipment (such as power station gantry cranes, casting cranes, cable cranes, etc.) and inclined belt conveyors are being promoted and applied.

Oil for electric hydraulic thrusters
The thruster has been equipped with hydraulic oil according to regulations when leaving the factory. If the thruster has been stored for a long time (more than 6 months), screw out the plug (see Figure 1) before use to check whether the oil level is normal. If the oil level does not reach the specified level, hydraulic oil should be added to the specified level (see Figure 1), otherwise the thruster cannot work properly. The hydraulic oil grade can be found in Table 2 (Mobil, Shell, and other hydraulic oils equivalent to the grade in the table can also be used), and the hydraulic oil filled must not contain impurities or dirt (it should be filtered). When adding hydraulic oil, the push rod should be slowly pulled up and down several times to remove air from the hydraulic cylinder and ensure sufficient oil is added.

The hydraulic oil used in the hydraulic brake system is selected based on the working environment during system design, and the viscosity of the hydraulic oil is an important reference index. The weather in your area is relatively cold, which can affect the viscosity of the hydraulic oil. Therefore, a good solution is to ask the design manufacturer. Because the system is designed by them, the designer has the right to speak. I myself also study hydraulic design, But hello, don't use hydraulic oil indiscriminately. Because the hydraulic system is quite particular about using hydraulic oil
