Dual oil electromagnetic hydraulic power unit

1、 Product Overview

This DC hydraulic power unit is an integrated small hydraulic pump station with dual electromagnetic directional valves. It adopts an integrated compact structure design and integrates a DC motor, gear pump, electromagnetic directional valve, oil circuit integrated block, and integrated oil tank. It is specially designed for small and medium-sized hydraulic actuators such as lifting platforms, car tailboards, flying wing cargo vehicles, boarding bridges, small lifting equipment, environmental sanitation equipment, and automatic chemical equipment. It can achieve independent lifting control of two oil cylinders and is the core oil supply power assembly of lightweight hydraulic systems.

2、 Core structure composition

DC drive motor

Standard configuration of 12V/24V DC permanent magnet motor, stable power output, high starting torque, and excellent low-temperature performance; The motor casing is coated with anti rust coating, sealed to prevent dust and water, suitable for outdoor use of vehicle mounted mobile devices, with low no-load noise and minimal vibration during operation.

High pressure gear oil pump

Equipped with high-precision aluminum alloy gear pump, it has high volumetric efficiency, stable output oil pressure, and a rated working pressure of up to 16MPa. It is pressure resistant and wear-resistant, not easy to leak internally, and can continuously supply oil without attenuation. It is suitable for small and medium-sized lifting loads.

Dual channel electromagnetic directional valve group

Equipped with two sets of electromagnetic directional valves (B1 and B2 ports are independently controlled in the figure), it can drive two sets of hydraulic cylinders respectively, switch the direction of oil flow through electronic control signals, and accurately control the rising, falling, and pressure holding actions of the cylinders; The valve block integrates an overflow pressure regulating valve, which can adjust the maximum pressure of the system as needed, automatically release pressure when overloaded, and protect the equipment from bursting pipes and overloading.

Integrated oil circuit block

Precision forging of oil circuit integrated blocks, optimization of internal oil circuit layout, reduction of external oil pipes, and reduction of oil leakage risk; Surface rust proof electroplating treatment, reserved standard hydraulic oil port, simple installation, and convenient maintenance.

Thickened sheet metal hydraulic oil tank

Black thick cold-rolled steel plate fuel tank, formed by integral bending and welding, with strong sealing and no oil leakage; The top is equipped with a red explosion-proof oil injection breathable cap and an oil level observation plug, making it convenient to add hydraulic oil and observe the liquid level; The bottom comes with an installation base, which can be directly bolted onto the frame or rack for stable installation.

Electric control wiring assembly

Standardized electromagnetic coil wiring leads, compatible with external handle switches and remote controllers, simple wiring, support remote control lifting, neat wiring, and less prone to short circuits.

3、 Core advantages of the product

Dual independent control

The dual solenoid valve and dual oil circuit design allows one power unit to simultaneously control two sets of hydraulic actuating components, saving the procurement cost of two pump stations and significantly reducing equipment installation space. It is suitable for double-sided lifting, synchronous/independent action conditions.

Compact integrated design

The motor, pump, valve, and fuel tank are horizontally integrated, with a compact size that does not occupy extra space in the equipment. It has strong adaptability for installation in vehicles and small devices.

Multiple safety protections

Built in overflow pressure protection, explosion-proof breathable oil cover, motor overload tolerance design, automatic overload pressure relief to avoid damage to oil cylinders, pipelines, and equipment; Power off automatically resets, and the load can smoothly fall back.

Durable and low maintenance

Gear pump wear-resistant structure, valve block integrated without redundant joints, greatly reducing oil leakage points; The fuel tank is rust resistant and corrosion-resistant, suitable for dusty and humid environments such as trucks, construction sites, and factory areas.

Customized flexibility

Support voltage customization (12V/24V/48V DC), customized fuel tank capacity, adjustable pressure, single/dual valve group adjustment, optional manual emergency descent function, can be matched with various non-standard hydraulic equipment.
