Problems solved by technology

Because these methods are independent of the accelerator control system, the parking stop time is long, and the structure is complicated, or it needs power supply to be implemented. In case of abnormality in the circuit, the emergency stop will fail. Such an emergency stop device is not only complicated to operate, but also reliable. Sex is not high

Abstract

The invention discloses an emergency shutdown device for an air-cooled diesel engine. The emergency shutdown device comprises a speed adjusting seat and a fuel spraying pump. The throttle of the fuel spraying pump is provided with a throttle pull rod provided with a baffle. A solenoid valve is arranged on the diesel engine, by opening and closing of the solenoid valve, a connected stirring rod is driven to move to stir the baffle to the minimum position of the throttle so as to cut off the fuel and shutdown the diesel engine. The device has the advantages that when abnormal situations, such as galloping, cylinder scoring and bearing score, occur during operation of the diesel engine, emergency shutdown can be performed, and safeties of the diesel engine, matching devices and operators are guaranteed.

Description

technical field [0001] The invention belongs to engine technology, in particular to an emergency stop device for an air-cooled diesel engine. Background technique [0002] Diesel engines are widely used in all aspects of life and production, but diesel engines may have mechanical failures when they are running at high speed, such as flying, cylinder scuffing or pulling. When there is a failure, we need to stop in time to ensure that the diesel engine And its supporting equipment and the safety of operators. At present, there are two kinds of emergency shutdown methods for diesel engines in China: gas cut-off and oil cut-off, including installing control valves at the inlet and exhaust ports, which can control the valve to cut off gas in emergency situations; or installing oil cut-off devices on the oil road, Oil can be cut off in an emergency when a fault occurs. Because these methods are independent of the accelerator control system, the parking stop time is long, and the...
