To introduce high efficiency steam boiler with 4 tons capacity pressure gauge and hydraulic press accumulator using steam boiler pressure gauge should pay attention to: 1, rated steam pressure is less than 2.45MPa steam boiler, the accuracy of pressure gauge must not be 2. 5; Rated steam pressure large or equal to 2.45MPa boiler, pressure must not be less than 1. 5 class. The diameter of the dial of the pressure gauge shall not be less than 100 mm to ensure that the operator can see clearly the surface pressure indicator value. 2. A red line should be drawn on the pressure dial of the steam boiler pressure gauge, indicating the maximum allowable working pressure. Steam boiler pressure gauges should be installed in a place that is easy to observe and wash. 4. Steam boiler pressure gauges should be checked at least once every six months, and should be sealed with lead after calibration. 5. Steam boiler pressure gauges should not have leakage of water and steam leakage in the connecting tubes of the pressure gauges of steam boilers. (4) the steam boiler pressure gauges should be checked at least once every six months and sealed with lead. 5. Otherwise, the pressure indicator value will be reduced. 6. The measurement range of the steam boiler pressure gauge should be adapted to the working pressure of the measured components, usually 1.5 times of the working pressure, preferably 2 times of the working pressure. Steam boiler does not have pressure gauge, the pressure gauge is damaged or the installation of pressure gauge does not meet the requirements, steam boiler pressure gauge should be stopped when one of the following conditions: 1, broken surface glass or dial calibration mold There is no clear paste; 2, no lead seal, lead seal damage or beyond the calibration period; 3, without pressure, the pressure gauge of the finite pin can not be restored to the limit pin, the infinite position of the gauge pointer deviated from zero data beyond the allowable pressure clothing; 4, gas leakage or pointer jump in the meter; 5, other defects that affect the accuracy of the gauge. Purpose of the accumulator: the accumulator is used in the hydraulic system of intermittent machinery, which stores the oil output of the hydraulic pump during intermittent or low-speed movement of the actuator, and when the rapid movement of the actuator requires a large flow rate, As an auxiliary energy source, together with the hydraulic pump, the oil pump is supplied to the system, thus the oil pump and the hydraulic pump are realized. The miniaturization of the whole hydraulic device absorbs the quick opening and closing of the impact hydraulic reversing valve and the sudden change of the load. The system will produce shock pressure, the darling will lead to vibration and noise, and even damage the machine. The accumulator can mitigate the impact pressure absorption pulsation of these fluids absorb and reduce the flow pulsation and pressure pulsation of various hydraulic pumps thus reducing the system noise and vibration. The damped accumulator acts as a gas spring and can be used to absorb the vibration between the fuselage and wheels of walking machinery such as vehicles. The balanced accumulator absorbs the gravitational potential energy of the vertical actuator (hydraulic cylinder) and its load as it falls. When the vertical actuator rises, the accumulator releases the original absorbed energy and supplies oil to the hydraulic cylinder together with the pump, thus realizing the balance and energy saving.
