Abstract

The invention discloses a magnetic fluid electric water pump for an engine. The magnetic fluid electric water pump comprises a shaft assembly, a driving disc, an impeller and a belt wheel. The driving disc and the impeller are arranged at the two ends of the shaft assembly respectively, and the belt wheel is installed on the shaft assembly. The magnetic fluid electric water pump further comprises an end cover, a coil block, a spacer bush and a terminal pad. A sealed space is formed by the end cover, the coil block, the spacer bush and the terminal pad in an enclosed mode. The driving disc is located in the sealed space, and the sealed space is filled with magnetic fluid. An electromagnetic coil with the magnetic field direction perpendicular to the driving disc is arranged in the coil block. The belt wheel is connected with the terminal pad. A rotating speed measuring device is further arranged in the end cover. An electric contact element is arranged at the top of the end cover. An electronic control unit of the engine is connected with the electromagnetic coil and the rotating speed measuring device through the electric contact element. The invention further provides a control method based on the magnetic fluid electric water pump. According to the magnetic fluid electric water pump for the engine and the control method thereof, control accuracy is improved effectively. Meanwhile, the water pump can be controlled to be at the optimal speed according to the temperature conditions of the engine, and thus efficiency is higher, and energy is saved.

Description

technical field [0001] The invention belongs to the field of engine cooling systems, and in particular relates to a magnetic fluid electric water pump for an engine and a control method thereof. Background technique [0002] It is widely used in all internal combustion engines used in mechanical engineering such as automobiles, tractors, ships, generator sets, and construction machinery. The water pumps in the cooling system are mechanically driven and have a fixed transmission ratio. No matter how your load changes, whether the water temperature is high or low, whether the discharge is good or bad, whether you need the pump to pump water, how much water to pump, etc., the pump works by pumping water according to a fixed transmission ratio. This design obviously cannot adapt to the requirements of the changing working process of the engine, and causes excessive cooling in many cases, causing damage to the engine, and a lot of time is a large amount of wasted energy. There i...
