BYT1-320Z/12 Explosion-Protected Electro-Hydraulic Thruster

BYT1-320Z/12 Explosion-Protected Electro-Hydraulic Thruster

The BYT1-320Z/12 is a heavy-duty, Explosion-Protected (Flameproof) electro-hydraulic thruster. It is a specialized actuator designed to operate braking systems and valve mechanisms in hazardous environments where explosive gases or dust may be present.

The model number breakdown is as follows:

BYT1: The series designation for Explosion-Protected electro-hydraulic thrusters (distinct from the standard YT1 or Ed series).

320: The Rated Thrust of 3200 N (approx. 320 kgf). This is a high-force unit.

Z: Indicates the structural design (typically integral/straight type).

12: The Nominal Stroke of 120 mm.

💡 Key Features & Characteristics

Explosion-Proof Certification:
The defining feature of this unit is its flameproof enclosure, which prevents internal sparks or heat from igniting the surrounding atmosphere.

Certification: It typically carries ExdI (for coal mines) and ExdII BT4 (for factories with flammable gases) certifications.

Safety: The junction box and motor housing are reinforced to contain explosions. The cable entry uses a rubber seal to ensure no gaps exist, maintaining the防爆 (explosion-proof) integrity.

High Thrust & Stroke:
With a thrust of 3200 N and a stroke of 120 mm, this unit is designed for large industrial brakes (such as large YWZ series drum brakes) or heavy-duty gate valves.

Robust Construction:

Material: The housing is typically cast aluminum or steel, designed to withstand harsh conditions.

Sealing: Equipped with high-quality seals to prevent oil leakage and ingress of dust/moisture (IP55 rating).

Operating Principle:
Like standard thrusters, it uses a centrifugal pump driven by the motor to generate hydraulic pressure, pushing the rod upward. When power is cut, the rod returns via gravity and the brake's return spring.

Environmental Tolerance:
Designed to operate in extreme temperatures, typically ranging from -25°C to +40°C, making it suitable for outdoor hazardous locations.

🏭 Typical Applications

The BYT1-320Z/12 is specifically engineered for hazardous zones in heavy industry:

Coal Mining: Underground conveyors and hoists where methane gas is present (ExdI).

Petrochemical & Refineries: Loading/unloading platforms and pipe racks where flammable vapors exist (ExdII).

Ports & Terminals: Handling flammable bulk materials (grain, coal dust).

Metallurgy: Coke oven plants and gas production facilities.

📋 General Technical Specifications

表格

Note: Because this is an explosion-proof device, maintenance is critical. The防爆 (flameproof) surfaces must never be scratched or damaged during installation. The cable entry must be sealed tightly with the provided rubber grommets to prevent the loss of explosion protection. Always verify that your power supply voltage matches the motor nameplate (380V or 660V) before connection.
