Intake bypass valve performance detection device using speed and oil pressure to accurately leak

Abstract

The invention discloses an air intake bypass valve performance detection device based on rotation speed and oil pressure accurate leakage. The structure of the air intake bypass valve performance detection device comprises a connecting valve, an air intake pipe and a performance detecting device; a rotating blade is driven by means of the rotation speed of air flow inside an air intake bypass valve, so that the rotating blade and a connecting shaft can be in linkage with each other so as to make a rotation quantitative disc inside a quantitative oil pressure device to rotate, so that an oil pipe can be squeezed, and therefore, oil inside the oil pipe flows to an oil pressure matching device; a pointer is matched with an oil pressure alarm and corresponding rotation speed matched oil pressure, the pointer of the oil pressure matching device records the corresponding change value of an induced oil pressure quantity; when the connecting valve leaks air, the internal airflow of the valve will be disturbed, and the speed rotation of the performance detecting device is affected, and a reading indicated by the pointer is smaller than a normal rotation speed matched value, it is indicatedthat an air leakage fault occurs on the air intake bypass valve; the rotation speech limit of the air intake bypass valve can be detected on the basis of a corresponding relation between a rotation speed and an oil pressure value indicated by the pointer, and therefore, classification can be facilitated, and the installation of vehicles with different horsepower can be facilitated.

Description

technical field [0001] The invention relates to a performance detection device for an air intake bypass valve which utilizes rotating speed and oil pressure to accurately leak, and belongs to the field of bypass valve detection devices. Background technique [0002] Many cars are equipped with turbochargers. In order to protect the engine and turbine to a certain extent, an electronically controlled intake bypass valve is generally installed next to the intake for protection. Inspection processing is required to know whether there is air leakage in the electronically controlled intake bypass valve. [0003] However, the existing valve performance detection device has the following disadvantages: [0004] Due to the different speeds, there will be different differences in the air flow inside the intake bypass valve, and then there will be different air pressure values. If there is a gap, different air leakage phenomena will occur under different air pressure values, that is,...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an intake bypass valve performance detection device that utilizes rotating speed and oil pressure to accurately leak, so as to solve the problem that the air flow inside the intake bypass valve is different due to different rotating speeds. If there is a gap, there will be different air leakage phenomena under different air pressure values, that is, the greater the speed, the greater the air leakage, but the detection is mostly simple to detect whether the intake bypass valve is There is an air leakage phenomenon, and it is impossible to carry out statistical processing on the corresponding speed leakage phenomenon, that is, it is impossible to carry out effective statistics on the performance of the intake bypass valve, and it is impossible to know the limit speed that the device can withstand to classify, and then it is impossible to correspond Corresponding car model to match the installation problem
