Q:How to check the fire valve pressure gauge as normal?: Building regulations: hydrant mouth pressure should not be greater than 0.8MPa; the water pressure is not greater than 0.5MPa; the "high regulation": the building height of not more than 100 meters, the most unfavorable pressure should not be less than 0.07MPa; more than 100 meters should not be less than 0.15MPa; the water gun full water column general building should not be less than 7 meters, a and B class of workshop, more than 4 layers of workshop and warehouse, and high-rise building multi-storey buildings and buildings more than 6 storeys height of not more than 100 meters should not be less than 10 meters, high-rise buildings should not be less than 13 metres.Spray system is: the worst point of the system, the work pressure should not be less than 0.05MPaSome people love to see the fire pump room pressure, the pressure must be large, the requirements are not less than those of numerical pressure above the highest point on the line, a building with a fire hydrant with a pressure gauge, you see that the pressure gauge on the line. Spray, you go to the top end of the test water pressure gauge on the line.

Q:The pressure gauge 0.1 stands for a few kilograms of pressure: Look at the range of your pressure gauge. If the measuring range is 0-1Mpa, then the 0.1 is 1 kilograms force

Q:Can you use the precision pressure gauge of level 0.25, measuring range (0~10) and MPa to verify the general pressure gauge of level 1, measuring range (0~6) MPa? Why?: According to the verification regulation requirements, the measurement ratio is 1/4, that is, the basic error of the standard device is not greater than the basic error of the checked table 1/4.0-10MPa, the basic error of the 0.25 standard table is 10*0.0025%=0.025MPa0-6MPa, the basic error of the 1.6 stage general pressure meter is 6*0.016*=0.096MPa0.025>0.096/4So, if you follow the rules strictly, this is out of the question. You must use the 0.4 or 0.25 stage precision watch of range 0-6MPa as standardIn other words, if you need a formal and effective certificate of approval, you can't; check yourself for reference, or you can

Q:What is the state of the warranty period for the ordinary pressure gauge?: The warranty period is stipulated by the manufacturer, usually 1 years.Since pressure gauges are measuring instruments, the importance of the pressure gauges should be graded according to ABC, and the calibration period should not exceed half a year.

Q:Measurement data, installed in the normal position, do not know whether to reverse installation, please professionals to help answer! Thank you Urgently!: Yes, the location does not affect the accuracy of the data

Q:The outlet flow of centrifugal pump to adjust the valve closed small, vacuum gauge and pressure gauge change?: The flow rate decreases, the loss is small, the vacuum of vacuum table decreases, the head increases, and the pressure of outlet pressure gauge increases

Q:How to control three-phase motor with electric contact pressure gauge: Electric contact pressure gauge contact capacity is about 1A, and the pressure gauge installation position basically has vibration phenomenon, unfavorable, so pull on contact, the first thing to consider is the pressure gauge and the measured pipe connected by a hose, pressure gauge and pressure gauge with fixed contacts to control the intermediate relay coil, often open contact of the intermediate relay to control the AC contactor coil, AC contactor main contact with motor.

Q:Fix a false SUPOR electric pressure cooker E4 fault, after inspection, the pressure switch is not in good contact. Replacement repair, but do not know how to adjust, worry about not repair to the original machine state will explode! Ask the heroes what coup adjustment!!!: The pressure switch is adjusted to the air valve. When the gas is out, it should be broken off. A little gas can be closed and the air valve is broken. Handshake, that's how I got it

Q:Is the accuracy level, not the type, thank you all: Pressure gauge accuracy class grade A, equivalent to 1 of the standard in our country, is a medium precision level of pressure gauges. Pressure meter accuracy level: 0.1, 0.16, 0.25, 0.4, 1, 1.5, 1.6, 2.5, 4. Among them, 0.1 is the lowest precision level, and the 4 is the highest precision level.A pressure meter is an instrument that measures and indicates higher than the ambient pressure with an elastic element as a sensitive element. It is widely used in almost all industrial processes and research fields. In the heat pipe network, oil and gas transmission, water supply system, vehicle repair and maintenance shop, and other fields can be seen everywhere. Especially in the control and measurement process, because the elastic sensitive element of mechanical pressure gauge has the characteristics of high mechanical strength and convenient production, the mechanical pressure gauge is widely used.

Q:For example, a 1.6 mpa. How do you measure it?!: Multimeter hit 2K (digital table), measuring remote table above three terminals in any two terminals: if it is 400 Ou mother, these two is high-end, low-end, and the rest that is the sliding end (middle end). Next, the access line, if the clock indicating pressure increases, while the display is declining, the high-end, low-end swap line.In general, three terminals, the bottom is the middle end, the middle is high-end, and the top is the low-end. Consistent with the electric contact pressure gauge.Have a try.
