Cylinder pressure measurement device

Abstract

Disclosed in the invention is a cylinder pressure measurement device comprising a connecting pipe (1). An indicator valve (2) and a sensor adapter (3) are connected to one end of the connecting pipe (1). And a pressure sensor (4) is connected to the sensor adapter (3). The device has the following beneficial effects: when an air cylinder pressure needs to be measured, the connecting pipe of the device is communicated with the air cylinder through a small hole formed in a cylinder cover directly. The device with a simple structure can be used conveniently; the damage on the sensor is reduced; the pressure wave interference is reduced; the cylinder pressure measurement precision is improved; and the damage on the pressure sensor is also reduced.

Description

technical field [0001] The invention relates to the technical field of high-power gas engines, in particular to a cylinder pressure measuring device. Background technique [0002] For high-power gas engines, it is particularly important to be able to accurately measure the cylinder pressure of the gas engine. If the measured cylinder pressure is too high or too low, it will have a great impact on the operation of the gas engine. If the cylinder pressure is too low, it is easy to cause gas The engine temperature continues to rise or even explode, and the cylinder pressure detection is too high, and the gas engine may not work normally. [0003] For the existing gas engine cylinder pressure detection equipment, the pressure sensor is often directly installed on the cylinder through the small hole in the cylinder head that communicates with the cylinder, but it is often easy to damage the pressure sensor due to frequent disassembly and assembly. , It is troublesome to disassem...
