Abstract

The invention provides a vacuum pump analog loading system. The vacuum pump analog loading system comprises a measuring and controlling end, an gas-supplementing gas pump and a pressure-regulating gaspump; a pressure balancing module is arranged at the measuring and controlling end, a left cavity, a right cavity and a membrane located between the left cavity and the right cavity are arranged in the pressure balancing module, and the membrane deforms and deviates in the corresponding cavity according to the vacuum degree difference between the left cavity and the right cavity; the gas-supplementing gas pump provides supplementing gas from the outside to a vacuum tank, the pressure-regulating gas pump is in gas connection with the left cavity and provides or extracts the gas in the left cavity according to the vacuum degree in the left cavity, and the right cavity is in gas connection with the vacuum tank. Negative feedback control over the vacuum degree in the vacuum tank is achieved,and continuous and stable gas supplementing and pressure regulating are achieved.

Description

technical field [0001] The invention relates to a vacuum pump simulation loading system. Background technique [0002] The front end of a conventional engine will contain several power accessories: generator, air conditioning compressor, vacuum pump, etc. Each power accessory has its own function on the whole vehicle, for example: the generator is driven by the engine crankshaft to realize high-speed rotation power generation, and the electric energy generated is supplied to various electrical appliances of the whole vehicle (such as: lights, central control display screen, ECU, etc. ). [0003] Among these power accessories, the vacuum pump is also a relatively important accessory. It generates a vacuum effect through high-speed rotation driven by the engine (generally directly driven by the engine camshaft), and provides a certain degree of vacuum for the vehicle's brake booster. The whole vehicle needs to run under load, that is, to generate a certain degree of vacuum b...
