Steam boiler pressure gauge should pay attention to matters 1, rated steam pressure less than 2.45MPa hot sale diesel steam boiler and pressure gauge accuracy not only in 2.5; rated pressure steam boiler child or equal to 2.45MPa, the pressure is too spread made not less than 1.5 level. Dial gauge diameter of not less than 100mm, in order to ensure the operation of the operator to see the surface of the pressure value shown. 2, should draw the red line on the dial gauge steam boiler, he pointed out that the maximum allowable working pressure. 3, the steam boiler pressure gauge should be provided at a convenient place to observe and purging, and to prevent the high temperature affected, freezing and vibration. 4, steam boiler pressure gauge should check at least every six months once the check should seal. 5, the pressure gauge connection tube steam boiler should leaks steam leakage phenomenon, otherwise it will reduce the pressure instruction value. 6, a steam boiler gauge scale element should be compatible with the measured working pressure, working pressure, typically 1.5; 3 times, preferably 2 times. When no steam boiler gauges, pressure gauges or pressure damage did not meet the requirements of the apparatus, boiler steam pressure gauges of the following circumstances, should stop using: 1, the surface glass breaking or blurred dial scale; 2, no seals , damage or seal verification period exceeded; 3, no pressure gauge pointer finite bit staple staple can not be restored to the limit at infinite set of bits from zero gauge pressure exceeds the pressure data bits garment allowable difference?; 4, the jump table or a pointer leak; 5, other effects gauge accurate defect. The use of the accumulator: the accumulator for a hydraulic accumulator system intermittent mechanical, hydraulic fluid may be stored in the actuator output when a batch or a low speed, and the actuator requires a large flow of fast-moving, as an auxiliary energy providing oil to the system together with the hydraulic pump, oil pump and thereby achieve miniaturization of the entire hydraulic system, to achieve the object of absorbing the impact energy sudden change fast opening and closing valve and the hydraulic load, the system generates a pressure shock, pet cause vibrations and noise, and even damage the machine. The accumulator can be alleviated, which absorb fluid shock absorber pressure pulsation absorbing accumulator, and reducing the pressure pulsation and flow pulsations of various pump, thereby reducing system noise and vibration. Having a damping effect of the gas spring accumulator, it can be used to absorb the mechanical vibrations between the body and the traveling wheel of the vehicle and the like. The accumulator can be balanced upright actuator (hydraulic cylinder) and gravity load decreases when the potential absorption into hydraulic energy store, while generating the rate-limiting resistance; upright when the actuator rises, releasing the original absorbing energy accumulator , together with the pump oil to the hydraulic cylinder, in order to achieve balance and energy.

Parties were quick to go to Shanxi Changzhi, boiler security popularize knowledge of this year, fast boiler should Changzhi City, Shanxi Province Special Equipment Supervision and Inspection (referred to Changzhi City, the special prosecutor) was invited for Changzhi City, more than 200 enterprises use boilers unit representatives of the gas boiler safety and technical training. Fang fast professional engineers with many years of use awareness of the boiler, in simple terms, the boiler eleven points to secure technical knowledge, has won numerous praise.

Increase productivity boiler system must first be optimized for verification, including the entire steam system for a complete analysis, and focus on some of the energy waste places. Via check can often find opportunities to save energy, increase productivity, and environmental protection have a positive contribution of. Check includes a steam generation, distribution, use and condensate recovery. The main steam waste requiring special attention place: exhaust gas boiler: boiler efficiency emissions system the most important indicators, the loss of energy is the most important place. Combustion air: general air enters the combustion furnace of the genus room temperature, require a lot of heating energy, i.e., the most commonly used power saving mode using a high temperature exhaust gas to preheat the combustion air of boiler, boiler efficiency can be significantly improved. The fuel / air ratio: Proper oil / gas mixture can only complete combustion, if the lack of air, combustion is incomplete, not only smoky pollution, environmental protests caused nearby residents, and easy carbonized grease gun and boiler heating tubes affect performance. If excess air is formed wasted energy, reducing boiler efficiency. Via the oxygen content of the tail gas can appropriately adjust the oil / gas ratio. Oil-fired boiler exhaust gas which content 3%, i.e., the excess air of about 15%, as the standard combustion control.

Pressure test must be carried out before the oil and gas boiler operation: either hot sale diesel steam boiler or hot water boiler in the boiler installation must be pressure test (ie, play water pressure). Because after long-distance transport, handling, installation, it is inevitable collisions and injuries through the boiler pressure test to discover defects promptly take appropriate measures in order to ensure the safe operation of the boiler. The following fuel gas-fired boiler to pressure test as an example:
