The boiler pressure gauge of how to choose in the mountains

Life everywhere have surprise. When we are in the process of arms hang road on foot, passing the farm rest, inadvertently see boiler pressure gauge on the hillside. For we do temperature and pressure gauge, the eye's instrument appear unusually sensitive. In the operation of the boiler pressure vessel, to avoid the soda pressure is too high and even exceed the maximum pressure of the container range values, or when handling error by pan an acute shortage of water in Shanghai, all can cause accidents such as the boiler exploded. In order to guarantee the safe operation of the boiler, must strengthen the monitoring of the boiler, so should be installed on the boiler pressure gauge. That we speak the choice of the boiler pressure gauge, by the way. 1, boiler pressure is less than 2. 5 mpa boiler, pressure gauge accuracy should not be less than 2. Level 5; Working pressure & ge; 5 mpa boiler, the precision of the pressure gauge should not be less than 1. Level 5; Working pressure & gt; The precision of the 14 mpa of boiler, pressure gauge should be level 1. 2, pressure on the dial scale value, should be the root of boiler working pressure, the pressure gauge measuring range should be selected according to the work of boiler pressure selection, scale range limit value shall be the working pressure of 1. 5 to 3. 0 times, had better be to 2 times. 3, the diameter of the gauge size, should guarantee the stoker personnel can clearly see that the pressure indicated value, the dial should not be less than 100 mm in diameter. Average height of up to 5 m boiler choose the diameter of the pressure gauge shall be not less than 200 mm; More than 5 m, the pressure gauge shall be not less than 300 mm in diameter. Height is high, it is best to 10 mm inner diameter seamless steel tube ( Such as phi 14 x2) , under the pressure measuring tube outlet led from the top of the boiler, the boiler the front or side before 1 from the ground. 7 m, fixed in the shell of the boiler for observation, and convenient for regular washing operation, loading and unloading of pressure gauge position. The interpretation of this to have some help?
