materials for making water tube boiler pipes
Why gas hot water materials for making water tube boiler pipes tube rupture it: ① water quality does not meet the formal standards, initiative without treatment, leading to the formation of scale pipe wall, affect the heat transfer effect, produce overheating tubes, strength weakens; ② boiler structure is not ideal, no circulation good, leading to local temperature is too high or because of improper manipulation start, so that the outer tube is formed coke; ③ at regular wear, thinning of the pipe wall; ④ tube mainly the mass, coarse material, or if the quality of the weld; ⑤ mentioned effect of temperature or cool down too fast down the drain, so that uneven heating pipes, resulting in breakage of the weld; ⑥ heat feed water is too low, so that the line is generated due to uneven heat changed appearance, resulting in seepage of the expansion port. Suddenly no electricity when the gas hot water boiler operation how to do gas-fired boiler | fuel boilers | steam boiler Environmental Equipment Co., Ltd.
Wuhan Yu Dahua Group Co., Ltd. is a cotton based, weaving, knitting and textile car decoration installation in one of the cross-industry, diversified and comprehensive export-oriented enterprise groups. 2017, the Group expanded production scale textile processing, the number of new production lines, the Group's original steam materials for making water tube boiler pipes can not meet the growing demand of orders in urgent need of a new steam boiler purchase. When selecting vendors steam boiler, the boiler output device side fast sustainable high quality steam attracted, decided to cooperate with the fast boiler. Fast art by side to the user site needs analysis, to provide two integrally condensing gas steam boiler (WNS4-1.25-Y.Q).
1, the working principle
Circulation pump: Its main role is to use up the water cycle, such as plumbing heating pipes in the hot water circulation pump is by cycling up. Low head and large flow, plays a significant role in the hot water boiler.
Premix module up and running off all power to the materials for making water tube boiler pipes 1. The premix boiler modules, opening the inlet valve of the gas pipe, drain valve. 2. Check the gas concentration in the gas pipeline, the check valve on the pipe flange connections without leakage phenomenon, if any should be handled immediately. 3. After the inspection is completed, the power sent to the controller module premix boiler, close the power switch of the burner. 4. Check that the controller parameters are normal, the system comprises a gas supply, water supply system, ignition system and flame protection, water protection system control, pressure control and protection system, electronic control box and the like. 5. Open premix boiler circulating pump module, observe thermometers, pressure gauges, and the corresponding water level gauge pipe fittings for water leakage. 6. The furnace boiler ignition should choose different methods of operation, after prolonged shutdown should be small fire. 7. After ignition must closely monitor the boiler water level. Ensure the water level is maintained at normal level. 8. When the premix module system pressure close to the operating pressure of the boiler, check the connections for leakage, disassembled flange connecting bolts, need to tighten again, should operate sideways, the force should not be excessive, to prevent the bolts off. 9. The premix normal operation of the boiler module (1) should be in the water level gauge in the visible range, the operation should be adjusted with changes in load level gauge must be washed once per shift. (2) boiler blowdown, should be carried out at high level, low load, the operation should make protective measures. . (3) periodic testing demineralized water, softened water boiler system to ensure that qualified.
