Problems solved by technology
[0004] The vortex fan with the same volume provided by the prior art has too small exhaust flow, and the vacuum generated by the air inlet is relatively high. If it is used to adjust the internal pressure of the crankcase, the exhaust gas from the combustion chamber of the engine will enter the crankcase more easily, which is easier for the environment. Pollution and Energy Waste
Other types of equal-volume fans, such as: centrifugal type, axial flow type, etc., the flow rate can meet the demand, but the vacuum degree of the suction port is low, and the internal pressure of the crankcase cannot be adjusted

The invention provides a vortex fan. The vortex fan comprises a belt wheel, an electromagnetic clutch, a transmission shaft, a pump body, an impeller, a pump cover and air inlet and outlet pipes, an annular flow channel is formed between the pump body and the pump cover and used for containing blades of the impeller, air inlets and outlets used for being connected with the air inlet and outlet pipes are formed in the pump body, the electromagnetic clutch is installed on the pump body through bolts, the transmission shaft sequentially penetrates through central shaft holes of the belt wheel, the electromagnetic clutch, the pump body, the impeller and the pump cover, and the on-off of the working current of the electromagnetic clutch is controlled through an engine ECU according to the feedback of a pressure sensor in a crankcase. According to the technical scheme, the pressure of the crankcase of a large diesel engine can be adjusted.
Description
technical field [0001] The invention relates to a vortex fan. Background technique [0002] When a large diesel engine works, the unburned mixture in the combustion chamber leaks from the piston ring into the crankcase under high pressure. These blow-by gases will escape from the crankcase into the atmosphere and cause pollution. If not removed in time, it will also dilute the crankcase. The engine oil deteriorates and causes premature wear of the engine parts. Therefore, it is necessary to use a fan to ventilate the crankcase and adjust its internal pressure. [0003] Ordinary vortex fans are mainly used in light industry, food, textile, agriculture, etc., and mainly have the characteristics of small size, low weight, and high output pressure. However, the crankcase pressure adjustment of large diesel engines puts forward higher requirements for the vortex fan. It must be able to adjust the crankcase pressure in real time with fast response and low energy consumption. It a...
