The BYT1 series explosion - protected electro - hydraulic thrusters are specialized drive control devices applicable in explosive environments. The following is a detailed description:
Application: Mainly used for operating electric - hydraulic block brakes, as well as for driving cylinders, ratchets, valves, etc. It can also operate various types of lever devices, enabling movements such as reciprocating, swinging, and circular motions. It is suitable for industries such as lifting and transportation, metallurgy, mining, ports, construction, and coal mines, especially for belt conveyors and mine hoisting equipment in coal mines.
Operating Conditions
Altitude: Below 2000m.
Ambient Temperature: - 20°C to + 40°C.
Relative Humidity: ≤90%.
Duty Cycle: Intermittent (S3 - 60%) and continuous (S1).
Power Supply: Three - phase AC, with a frequency of 50Hz. The rated voltages are 380V/660V or 660V/1140V, and the voltage fluctuation should not exceed - 10% to + 10%.
Explosion - Proof Features: The explosion - proof performance complies with the provisions of GB 3836 - 2010, and the explosion - proof mark is "Exd I Mb", which is applicable to explosive gas hazardous locations in coal mines and Class I, Class IIA, Class IIB, with a temperature group of T1 - T4.
Structural Characteristics: The shell is made of cast aluminum alloy, which is lightweight and beautiful in appearance. The motor is of a non - oil - immersed structure, with B - class or F - class insulation (according to user requirements), having good heat resistance and a long service life. The motor shaft and push rod are surface - treated by hard chrome plating, which can significantly extend the service life of the seals. The electrical enclosure protection level reaches IP55.
Model Specifications: There are various models such as BYT1 - 18ZB/2, BYT1 - 25ZB/4, BYT1 - 45Z/4, BYT1 - 90Z/6, etc. Different models have different rated thrusts, rated strokes, and motor powers. For example, the rated thrust of BYT1 - 18ZB/2 is 18kg, and the rated stroke is 25mm, with a motor power of 0.06kW; while the rated thrust of BYT1 - 90Z/6 is 90kg, and the rated stroke is 60mm, with a motor power of 0.25kW.
