And hot water boiler furnace pressure gauge how should choose?

Recently a lot of industrial boiler, hot water boiler plant manufacturers find us, such as asking where with pressure gauge, a lot of people for the use of these pressure gauge is not very understanding, instrument today about the specific talk about: selecting should choose according to boiler pressure, the scale range limit shall be the working pressure of 1. 5 - 3. 0 times. In the work of boiler, the actual situation is the job of the boiler operation pressure is always lower than the rated pressure on the nameplate, industrial steam boiler and hot water heating boiler. For example 4 t/h steam boiler, pressure rated 1 mpa, factory if according to 1. 5 times come equipped with a pressure gauge shall be equipped with 1. 6 mpa manometer. If the user with the need of production process, the actual operation in 0. 5 mpa pressure which can satisfy the technological requirements, the operating range, pressure gauge pointer in range of less than a third of the position, the pointer turning Angle is small, the selection of pressure gauge measuring range is too big. So is a hot water boiler, such as heating boilers rated pressure of 0. 7 mpa, equipped with a pressure gauge shall be 1 mpa or 1. 6 mpa, is equipped with 1 mpa pressure gauge, be afraid of the hydrostatic test pressure gauge is used when the overload, and equipped with a range of 1. 6 mpa pressure gauge. The actual runtime, as long as 0. 2 mpa can meet the heating requirements, the location of the pressure gauge pointer refers to the range of one 8, it is hard to believe that the accuracy of the pressure gauge and sensitivity. Should be adopted to solve the above problem, two kinds of pressure gauges, namely when the water pressure test, the boiler plant according to the rated pressure of the pressure gauge; From the above introduction, both in the boiler pressure gauge and pressure gauge used in the hot furnace must have a certain pressure range to the correct use of pressure gauge, boiler work can run efficiently right!
