when secondary high pressure direct connection portable compressor has just started, low pressure (LP) cylinder, pressure in high-pressure cylinder and gas holder is all zero (gauge pressure), the exhaust pressure and the suction pressure that are secondary high pressure direct connection portable compressor are all zero, work along with secondary high pressure direct connection portable compressor, the gas that secondary high pressure direct connection portable compressor is discharged enters gas holder, therefore, pressure in gas holder constantly raises, that is to say, the exhaust pressure of secondary high pressure direct connection portable compressor is constantly changing, when the pressure in gas holder is elevated to setting pressure, secondary high pressure direct connection portable compressor will quit work automatically.In the whole working procedure of this explanation secondary high pressure direct connection portable compressor, its operating conditions is all constantly changing, and pressure ratios at different levels also all are among variation.Study the transient working process of secondary high pressure direct connection portable compressor, will know the transient state air pressure of high and low pressure cylinder, storage tank and inter-stage copper pipe.The utility model provides a kind of interior transient state pneumatic shuttle of high and low pressure cylinder, storage tank and inter-stage copper pipe of testing secondary high pressure direct connection portable compressor for this reason.
The model utility content
The purpose of this utility model is for the deficiencies in the prior art, and a kind of secondary high pressure direct connection portable compressor transient pressure detection device for transient state air pressure in high and low pressure cylinder, storage tank and the inter-stage copper pipe of test secondary high pressure direct connection portable compressor is provided.
The purpose of this utility model is achieved through the following technical solutions:
Secondary high pressure direct connection portable compressor transient pressure detection device, it mainly contains computer, be located at the low pressure sensor on low pressure (LP) cylinder, the high pressure sensor that is located on high-pressure cylinder consists of, and described low pressure sensor and high pressure sensor send the pressure information in low pressure (LP) cylinder, pressure information in high-pressure cylinder to the computer II by datawire respectively.
Also comprise the computer I and be located at low pressure (LP) cylinder and high-pressure cylinder between connecting tube on baroceptor, described baroceptor sends the pressure information in connecting tube to the computer I by datawire.
Also comprise the sensor that is located on storage tank, described sensor sends the pressure information in storage tank to the computer I by datawire.
The beneficial effects of the utility model are: because above-mentioned detection device has been set up in employing, therefore can be easily carry out in good time detection to the transient state air pressure in high and low pressure cylinder, storage tank and the connecting tube (inter-stage copper pipe) of secondary high pressure direct connection portable compressor, thereby provide foundation for the optimal design of compressor.
