Application ScopeThis electro - hydraulic pusher is suitable for many industrial fields due to its stable performance. It is often used as a supporting component for plows and unloaders. Besides, it has a wide range of applications in metallurgy, mining, electric power, coal, machinery, grain processing, chemical industry, water conservancy and transportation industries. For example, it can provide power for the opening and closing of material conveying equipment in coal - fired power plants, and drive the action of related mechanisms of smelting auxiliary equipment in steel enterprises. It is also applicable to remote and high - altitude dangerous areas and can be connected with computers for centralized program control.
Prominent Advantages
Overload automatic protection: When the external force on the piston rod exceeds the rated output force or the piston reaches the end of its stroke, the oil pressure in the oil circuit will rise to the set pressure. At this time, the overflow valve will overflow quickly and accurately, which can prevent the motor from being burned out even if it is still running, thus realizing automatic overload protection.
Pressure self - locking function: The oil circuit integrated block of this model is designed with a pressure self - locking mechanism. When the motor stops running, the piston rod can immediately stay at the current position, and the pressure oil in the oil circuit maintains pressure. This feature can avoid the displacement of the pushed component due to external forces and ensure the stability of the equipment in the static state.
Convenient stepless adjustment: Within its rated output force, stroke and speed ranges, users can perform stepless adjustment according to actual working requirements. This flexibility enables it to adapt to different working conditions and matching equipment needs, which is an advantage that ordinary electric push rods and air cylinders do not have.
Easy installation and maintenance: As an integrated structure, it has a compact overall design. Unlike pneumatic or hydraulic transmission systems that require configuring air compressors, hydraulic stations and complex pipelines, this electro - hydraulic pusher can be installed directly, saving installation space and initial investment costs. Meanwhile, its closed structure is not easy to absorb dust or enter water, which reduces daily maintenance workload.
Working PrincipleIt realizes power transmission and mechanical action based on the integration of mechanical, electrical and hydraulic technologies, and the specific process is as follows:
Pushing action: When the motor is powered on and rotates forward, it drives the bidirectional gear pump to operate. The gear pump outputs pressure oil, which is delivered to the working oil cylinder through the integrated oil circuit block. Under the pressure of the hydraulic oil, the piston rod in the oil cylinder extends outward to complete the pushing action and drive the connected mechanical components to run.
Pulling action: When the motor reverses after the power supply is adjusted, the bidirectional gear pump will change the direction of oil output. The pressure oil enters the corresponding oil chamber of the oil cylinder through the oil circuit integrated block. Under the action of the oil pressure, the piston rod retracts inward to realize the pulling action.
Stopping and locking: When the motor stops working, the pressure self - locking mechanism in the oil circuit integrated block starts to work. The pressure oil in the oil cylinder is kept in a pressure - maintaining state, and the piston rod is fixed at the current position without displacement, so as to ensure the stable state of the whole equipment system.
