Sunward SWE385ES hybrid excavator has many advantages

Now, energy saving, emission reduction, green environmental protection, has become a hot key to promote the sustainable development of Chinese economic health, as engineering machinery as trailbreaker in the infrastructure construction, the implementation of a mandatory policy has also ushered in the "country of three" emissions, engineering machinery industry officially entered the era of environmental protection and energy saving ".

With the three phase of the new emission model quietly listed, Sunward Intelligent as "China's construction machinery industry pacesetter", comply with the requirements of the times, developed SWE385ES hybrid excavator.

Sunward SWE385ES is in a large excavator platform in the tradition, developed a hybrid system model of boom structure and hydraulic energy storage unit based on the key breakthrough multi cylinder self balancing arm driven interaction and potential energy recycling, rotary flow, self energy recycling, energy recovery and operation performance of the collaborative optimization control technology based on authorization to a "boom", "work unit energy recovery hydraulic system" as the core of the 14 invention patents, developed a series of energy-saving excavator patented products, to achieve energy efficient recovery of vehicle recycling, optimization, high pressure storage engine fuel economy energy system safe and arm and the rotary composite movement good coordination capability, improve work efficiency in excavator and reduce vehicle fuel consumption. Engine power 183.9kw/2000rpm, standard operating conditions, the overall fuel consumption decreased by 18.2%, smoke emissions reduced by 58%.

1, fuel saving

Sunward SWE385ES hybrid excavator has the hydraulic hybrid power system with independent intellectual property rights. It can recycle the potential energy of the working device, improve the energy utilization of the whole machine, and significantly reduce the fuel consumption. In addition, sunward pioneered the FSM flow self matching rotary energy saving technology, effectively eliminating the energy loss in the operation project.

2, efficiency

Sunward SWE385ES hybrid excavator has a series of bucket with different 1.6~2.4m3 capacity, the maximum bucket capacity can be increased by more than 30%, more earthwork per bucket. The new boom structure with multi hydraulic cylinder and high density and large capacity accumulator can increase the boom faster and shorten the time.

3, environmental protection

The engine power 183.9kw/2000rpm of sunward SWE385ES hybrid excavator, under the standard operating conditions, the fuel consumption of the whole engine is reduced by 18.2%, and the smoke emission is reduced by 58%. Balance engine load fluctuation, engine work in high efficiency range, greatly improve overload "black smoke" phenomenon. The engine works smoothly and has little vibration, which can effectively reduce noise over 3db.

4, economy

Under the standard operating conditions, compared with the traditional hydraulic excavator, the maximum fuel consumption can be reduced to 30%, and the average energy saving fuel cost per hour is 45 yuan, which can save nearly 230 thousand yuan of fuel cost per user per year.
