Hydraulic power unit with pressure gauge valve block

1、 Product Overview

This is a horizontal AC industrial hydraulic power station, which adopts a horizontal integrated layout of motor, pump valve block, circular steel oil tank, and is equipped with an external precision pressure gauge. It is compatible with AC220V single-phase/AC380V three-phase industrial mains power and is specially designed for fixed hydraulic equipment that requires real-time pressure observation. It is widely used in lifting platforms, boarding bridges, tire treaders, hydraulic presses, automatic chemical equipment and other working conditions. It can intuitively read the system oil pressure, accurately regulate the pressure, and control the load.

2、 Core component analysis

Aluminum shell AC industrial motor

All aluminum alloy heat dissipation body, with fully covered heat dissipation fins for continuous operation and low temperature rise; Sealed junction box with high voltage warning label, protection level IP54, dust-proof and splash proof, supports long-term continuous start stop; The tail of the motor is marked with a turning arrow, which is easy to install and debug, with stable power output and low noise.

Integrated valve block+external pressure gauge assembly

Precision forging integrated oil circuit valve block, with reserved two standard hydraulic oil ports and built-in overflow pressure regulating valve; The radial oil pressure gauge is installed on the side of the valve block, which can display the working pressure of the system in real time and intuitively. No external instrument is required for pressure regulation, resulting in higher debugging efficiency; The valve group can be equipped with single/double electromagnetic directional valves to achieve the functions of oil cylinder lifting, pressure holding, and pressure relief.

High pressure aluminum alloy gear pump

High precision gear pump, high volumetric efficiency, rated pressure up to 16MPa, wear-resistant and anti leakage, stable oil supply, suitable for small and medium-sized lifting and clamping loads.

Horizontal circular thickened steel fuel tank

One piece cold-rolled steel plate welded cylindrical fuel tank, black anti-corrosion paint, pressure and deformation resistance; The top red explosion-proof breathable oil cap balances the air pressure inside the oil tank and facilitates the filling of hydraulic oil; The circular horizontal structure saves vertical installation space for equipment, adapts to narrow installation positions of the rack, integrates a bottom mounting base, and is firmly fixed and shock-absorbing.

Integrated installation bracket

The pump, valve, and fuel tank share a metal support base, making the overall structure compact, reducing assembly gaps, and minimizing operational vibrations. On site installation only requires bolt fixation, and the assembly process is simple.

3、 Core advantages of the product

✅  Comes with pressure gauge, pressure visualization

Equipped with an external oil pressure gauge as standard, the system pressure can be read in real-time and intuitively. No additional external instruments are required for pressure regulation and testing, ensuring precise and efficient debugging to avoid equipment damage caused by overpressure.

✅  AC industrial power supply, capable of long-term continuous operation

Adapt to fixed mains power supply in factories, distinguish from vehicle mounted DC pump stations, support 24-hour intermittent continuous operation, suitable for fixed equipment in assembly lines and workshops.

✅  Circular steel fuel tank is sturdy and durable

Thickened steel plates are impact resistant and not easily deformed. Compared to plastic fuel tanks, they are resistant to high temperatures and oil stains, with no risk of aging or cracking. The anti rust coating prevents oil circuit corrosion and blockage.

✅  Integrated valve block with few leakage points

The built-in integrated design of the oil circuit reduces the number of external copper pipe joints, greatly reducing the probability of oil leakage; The valve block is reserved with standardized oil ports, making it convenient to expand the accessories of directional valves and one-way valves.

✅  Multi specification flexible customization

Support motor power of 0.75-3kW, oil tank capacity of 3-8L, single/dual electromagnetic commutation, manual emergency descent, and customized pressure gauge range.
