Refrigerant pressure gauge

Refrigerant pressure gauge

The refrigerant pressure gauge is used to measure the working pressure of the refrigeration unit at present. The key is to monitor the working pressure of different refrigerant links in the system

Refrigerant pressure gauge detail:

Refrigerant pressure gauge is also called refrigerant gauge or fluorine gauge. It is to enable the actual operation and maintenance personnel of the machine and equipment to clearly grasp the management status of the machine and equipment

一、怎样载入高压低压表的工作压力值:
1、底压表的五圈为工作压力标值鲜红色线,要以MPa为企业的工作压力标值线,如表针指到“0.2”即当今的工作压力为0.2MPa。
人们再讨论一下髙压表有怎样读值,五圈为工作压力标值鲜红色线,要以MPa为企业的工作压力标值线,如表针指到“3”即当今的工作压力为3MPa。
2、不一样压力单位的变换
1(MPa)=145(psi)=10.2(kg/cm2)=10(bar)=9.8(atm) 。
1(psi)=0.006895(MPa)=0.0703(kg/cm2)=0.0689(bar)=0.068(atm) 。
1(bar)=0.1(MPa)=14.503(psi)=1.0197(kg/cm2)=0.987(atm) 。
1(atm)=0.101325(MPa)=14.696(psi)=1.0333(kg/cm2)=1.0133(bar)。
兆帕(MPa),磅/平方英寸(psi),公斤/公分(kg/cm2),巴(bar),大气压力(atm)
二、怎样载入高压低压表的溫度值
无论是高压低压充油气压表,其从外向里数。
第一圈为R22冷媒翠绿色 。
第二圈为R134a冷媒深蓝色。
第三圈为R404a冷媒鲜红色。
第四圈为R407c冷媒翠绿色。
五圈为工作压力标值鲜红色线,要以MPa为企业的工作压力标值线。
最后圈为工作压力标值灰黑色线,要以Psi为企业的工作压力标值线。
1、底压表,如每台冷冻设备冷媒应用R22,运作时底压工作压力0.27MPa相匹配的溫度约为-9度,如每台工业冷水机冷媒应用R134a,运作时底压工作压力0.3MPa相匹配的溫度约为9度。
2、髙压表,如每台工业冷水机冷媒应用R22,运作时髙压工作压力1.8MPa相匹配的冷疑溫度约为50度,如每台工业冷水机冷媒应用R134a,运作时髙压工作压力1.4MPa相匹配的冷疑溫度约为55度。
填补表明:
1、兆帕(MPa),磅/平方英寸(psi),公斤/公分(kg/cm2),巴(bar),大气压力(atm) 。
2、不一样的气压表的压力单位将会不同,读工作压力前需看前表壳上的标志
3、中央空调通常应用:R22、R134a、R407C、R410a、R32(易燃易爆物品);冷冻冷藏通常应用:R22、R404a、R717氨(易燃易爆物品)。
4、在制冷压缩机沒有运作时工作压力为均衡工作压力,即高矮工作压力同样,其工作压力值与工作温度或储水箱温度相匹配。
如:R22工作温度30度时,气压表的均衡工作压力约为1.1MPa。
如:R22工作温度10度时,气压表的均衡工作压力约为0.6MPa。
