A portable generator set (1) comprises an engine (6), a generator (7), a fuel tank (8), and a housing (5). The engine (6), the generator (7), and the fuel tank (8) are accommodated in the housing (5). The fuel tank (8) is constructed by a fuel tank housing (805), a fuel tank port (801), a fuel tank cap (802), and a fuel tank top surface (808). A protrusion structure protruding outward is provided on the fuel tank top surface (808). A hollow cavity (809) communicated with the inner cavity of the fuel tank (8) is formed on the inner side of the protrusion structure, such that fuel in the fuel tank (8) can enter the hollow cavity (809) when the generator set (1) is obliquely reclined. The generator set can be obliquely reclined, thereby improving security and facilitating transportation and storage of the generator set.

A portable generator includes a CO sensor module to sense CO levels in the environment surrounding the portable generator. The CO sensor module senses high levels of CO and sends a signal to shut down the engine on the portable generator. The CO sensor module alerts the user by emitting an LED light whether the CO sensor module is functioning properly, improperly or if high CO levels are detected. The CO sensor module is removable from a control panel of the portable generator to be replaced or maintained by the user per a replacement or maintenance schedule.

A power generation system including a controller area network (CAN) bus and a first power source having a first electrical generator, a first controller connected to the CAN bus, and a first resistor. The power generation system also includes a second power source having a second electrical generator, a second controller connected to the CAN bus, a second resistor, and a user-activated switch. The user-activated switch is movable between a first position, so that the second resistor acts as a terminating resistor to signify another end of the CAN bus and a second position so that the second resistor is prevented from acting as a terminating resistor.

The present invention discloses a method of a mobile power generation system. A power generation apparatus is respectively quickly connected, through expansion joints, to an intake assembly and an exhaust duct which are separately transported, to implement the quick installation and connection of the power generation system at the fracturing operation site. Two conveyances are respectively provided for the intake assembly and the exhaust duct to achieve more flexible adjustment during connection. While the position of the power generation apparatus is fixed, the intake assembly is moved to connect to an intake chamber of the power generation apparatus, and the exhaust duct is moved to connect to an exhaust collector of the power generation apparatus.

A device conveying a solid material into a radially-arranged stockpile. The device has a trailer chassis, with at least one wheeled axle at a first end thereof and, at a second end thereof, means provided for attaching the chassis to a tractor in a mobile condition and for fixed mounting in an operational condition. A stacking conveyor is mounted near the first end of the chassis. A power unit for generating electrical and hydraulic power is positioned on the chassis. A feed system is mounted to the chassis and extends generally along the length thereof from the second end to the first end, to receive the solid material at the second end and transport the solid material to the stacking conveyor.

A generator system comprising a generator and an engine positioned within an enclosure, the engine having an engine coolant system and an air intake; a fan positioned to force air through the heater core; a low temperature fluid circuit comprising a heater core positioned within the enclosure, a first coolant heater in fluid communication with the heater core, and a first pump in fluid communication with the first coolant heater and configured to pump heated coolant from the first coolant heater to the heater core; and a high temperature fluid circuit comprising a radiator, second coolant heater, and a second pump in fluid communication with the second coolant heater and configured to pump heated coolant from the second coolant heater through the high temperature fluid circuit, wherein the low temperature fluid circuit and the high temperature fluid circuit are each in fluid communication with the coolant system of the engine.

The present invention discloses a system for providing mobile power, in which the required equipment for the power supply system at fracturing fields as well as connection cables and connection hoses are integrated properly, assigned onto three transport vehicles for movement and effectively connected. An intake component and a turbine generation system are combined on a first transport vehicle and installed together, then transported to customer sites directly, thus saving the installation time at the user sites. The two different designs on the locations of an exhaust stack and an exhaust silencer not only meet the requirements of road transportation, but also meet the requirements of exhaust gas emission during operations.
