Abstract
The invention discloses a high-power gas engine air cylinder provided with a pressure measuring device. The high-power gas engine air cylinder comprises an air cylinder head (1). A cylinder pressure sensor adapter (2) is arranged on the air cylinder head (1). The cylinder pressure sensor adapter (2) is tubular. One end of the cylinder pressure sensor adapter (2) stretches into the air cylinder and is communicated with the air cylinder, and the other end of the cylinder pressure sensor adapter (2) stretches out of the air cylinder. The high-power gas engine air cylinder has the beneficial effects that the channel effect is eliminated, the interference of pressure waves is eliminated, and thus measurement data are more accurate; meanwhile, mounting and dismounting become convenient and rapid by means of the cylinder pressure sensor adapter, and the damage to equipment is reduced.
Description
Technical field
The present invention relates to high power gas machine technology field, specifically, is a kind of high power gas machine cylinder with pressure-detecting device.
Background technique
For high power gas machine, the cylinder pressure that can measure gas engine is accurately particularly important, the cylinder pressure measured is too high or too low all can cause larger impact to the operation of gas engine, cylinder pressure detects too low, gas engine constant temperature is easily caused to raise the danger such as even blast, cylinder pressure detects higher, and gas engine may cause cisco unity malfunction again.
For existing gas engine cylinder pressure detection facility, often through the aperture that cylinder head is communicated with cylinder, be connected with cylinder pressure sensor through connection set, the wave interference but this mode is easily stressed, thus cylinder pressure testing precision is low, and this device connects complicated, dismantle loaded down with trivial details, dismounting also easily causes device damage frequently.
Summary of the invention
In order to solve the problem, the present invention proposes a kind of high power gas machine cylinder with pressure-detecting device, cylinder head arranges cylinder pressure sensor joint, one end of cylinder pressure sensor joint is stretched into cylinder and is communicated with cylinder, after the other end assembling of cylinder pressure sensor joint, height passes top surface of cylinder cover, eliminate the interference of pressure wave, improve signal element output accuracy, make cylinder pressure sensor convenient to disassembly.
For achieving the above object, the concrete technological scheme that the present invention adopts is as follows:
A kind of high power gas machine cylinder with pressure-detecting device, comprise cylinder head, cylinder head is provided with cylinder pressure sensor joint, described cylinder pressure sensor joint in a tubular form, one end of described cylinder pressure sensor joint is stretched into cylinder and is communicated with cylinder, and the other end of described cylinder pressure sensor joint passes cylinder.
By above-mentioned design, cylinder pressure sensor joint is connected with high power gas machine cylinder, and when carrying out cylinder pressure and measure, directly by stretching out the cylinder pressure sensor joint of cylinder, be connected with cylinder pressure sensor, convenient disassembly, testing precision are high.
Further, described cylinder pressure sensor joint overall length 220 millimeters.
Further describe, described cylinder pressure sensor joint vent internal diameter is 5 millimeters to 7 millimeters again.
Further describe, conveniently dismounting, the length that described cylinder pressure sensor joint passes cylinder is 70 millimeters again.
Preferably, the material of described cylinder pressure sensor joint is stainless steel material.
Further describe again, conveniently dismounting, the other end termination of described cylinder pressure sensor joint is provided with internal thread and outside thread and square toes.
Beneficial effect of the present invention: cylinder pressure sensor joint and cylinder head are threaded connection and end face seal, the channelling effect existed when the joint of this length can eliminate measurement, namely eliminates the interference of pressure wave, improves output accuracy.Meanwhile, cylinder pressure sensor joint makes dismounting become convenient and swift, decreases the injury to equipment.
