The special generator set for oil field system is a special power generation equipment tailored according to the operating environment and working conditions of the oil field. The equipment uses Hanma engines and Mecc Alte generators. The top hoisting frame and chassis hoisting multiple hoisting methods are convenient for installation and transfer. The chassis cover is made of thick steel plate with high wear resistance. Heavy-duty door locks and hinges. The track-type isolation wind and sand system can prevent sand, dust, and fly insects according to different operating conditions, and is convenient for maintenance and replacement. In view of the special oilfield environment, the humanized ladder-climbing design of the outer cover, the design of multiple emergency stop buttons, the design of the smoke suppressor, the design of the built-in fire extinguisher, the design of the fuel port, and the design of oil level display greatly improve the operating safety of the unit. The high-efficiency soundproof enclosure is equipped with LED inspection lights. The internal space of the outer cover is reasonably arranged. The diagonally-drawn side panels isolate the space from the independent muffler system and the fuel tank system. The bending design and the installation of insulation cotton are adopted for each shift to ensure strength and heat insulation. The muffler is installed on the upper part of the side panel to facilitate the smoke and rain to dissipate heat in time. The independent fuel tank is designed to be installed on the lower part of the side partition panel and above the chassis. It does not directly contact the outside to prevent direct contact of gravel on the oilfield ground when the unit is running. , Thereby reducing friction and increasing the service life of the fuel tank, and the independent fuel tank can be replaced at any time for easy maintenance. The fuel system pipeline joints are mostly detained. The big brand Goodyear fuel pipes have long life and corrosion resistance, and the fuel in the fuel system first passes through the pre-designed water tank The cooling core in the engine is cooled before entering the engine to ensure the safety and reliability of the fuel supply system. The installation of a rigid sleeve outside the flexible shock absorber can reduce the resonance of the machine during uneven subgrade operation.
