Self-starting 50KW three-phase diesel generator price


Starlight manufacturer provide self-starting 50KW three-phase diesel generator price, brand can be Cummins, Volvo, Perkins, Deutz, Yuchai, Shangchai etc.


Most are driven by lower speed turbines or diesel engines. The number of motor poles ranges from 4 poles to 60 poles, and even more. The corresponding rotational speed is 1500 to 100 rpm and below. Due to the low rotational speed, salient-pole rotors that require less material and manufacturing processes are generally used.

Each pole of salient-pole rotor is usually overlapped by 1-2 mm thick steel plate, which is integrated by rivets. Excitation windings are arranged on the pole. The excitation winding is usually made of flat copper wire. The pole shoe of the pole is often equipped with a damping winding. It is a short circuit formed by the bare copper strip in the damping groove of the pole shoe and the copper ring welded at both ends. The pole is fixed on the rotor yoke, which is made of cast steel. Salient pole rotors can be divided into horizontal and vertical types. Most synchronous motors, synchronous cameras and generators driven by internal combustion engines or impulse turbines are of horizontal structure, while low-speed and large capacity hydro generators are of vertical structure.

The rotor of the horizontal synchronous motor is mainly composed of a main magnetic pole, a yoke, a field winding, a collector ring and a rotating shaft. Its stator structure is similar to that of asynchronous motor. The vertical structure must bear the gravity of the rotating part of the unit and the downward pressure of water with the thrust bearing.In the large capacity hydrogenerator, the force can be as high as four or fifty meganewtons (about equal to the gravity of four or five thousand tons of objects), so the structure of the thrust bearing is complex, and the processing technology and installation requirements are very high. According to the location of the thrust bearing, the vertical Hydrogenerator can be divided into two types: suspension type and umbrella type. The suspension type thrust bearing is placed on the upper or middle part of the upper frame, and it runs stably on the machine when the rotating speed is high and the ratio of rotor diameter to core length is small. The umbrella type thrust bearing is placed on the lower frame under the rotor or on the top cover of the water turbine. The load-bearing frame is a smaller lower frame, which can save a lot of steel and reduce the height of generator and workshop from the base.

Technical Parameters of Boduan 500KW Weichai Generator Set 6M33D572E200

  The 6M33D633E200 diesel engine is a special-purpose diesel engine for land-based power generation in the M33 series. It is a new-structure power generation diesel engine with a centrally - located turbocharger developed by Weichai Power Co., Ltd. in 2016. Continuous Power (COP): The maximum power at which the diesel engine can run continuously under a constant load with no limit on the annual operating hours. It is the ISO standard power. Prime Power (PRP): The maximum power at which the diesel engine can run continuously under variable loads with no limit on the annual operating hours. It is an ISO standard power that allows a 10% overload. Standby Power (ESP): The maximum power in a certain variable - power series that the diesel engine can operate for up to 200 hours per year. It is an ISO standard power with limited fuel consumption.   Operating Conditions and Applications of Baudouin  500KW Weichai Generator Set  Diesel Engine Power Classification Operating Co...

Yuchai Is Super Confident in Its Innovation

Founded in 1951, with 30 wholly-owned, holding and joint-stock subsidiaries, Guangxi Yuchai Machinery Group Co., Ltd. (hereinafter referred to as the Yuchai Group) is an internal combustion engine manufacturing base with the most complete spectrum of products in the country. In recent years, machinery manufacturing industry has been dropped off influenced by domestic and foreign economic situations, especially domestic overcapacity and unreasonable product structure. Reversely, Yuchai has sold over 3 million engines with the annualized revenues amount to RMB 40 billion. Over the years, as China ’ s largest engine R&D manufacturing base, Yuchai adjusts and optimizes its industrial structure and constantly strengthens its capacity for independent innovation. Therefore, the key technology continues to be the top in the sector for further keeping its own top leader in the industry. Innovation-Driven In 2013, seven world-class diesel-engine products for high-s...
