How to use a small steam 10t boiler machine supplier estonia feed pump minimum energy consumption in the process we use small steam boiler, due to its many accessories are set, so it would be more convenient to use. But how can the use of small steam boiler feed pump minimum energy consumption, which is to pay attention to certain methods below to find out more to explain. Some literature also recommended the drive, but the high investment drive, and often not achieve the desired benefits. In this paper, horizontal multistage centrifugal pump, for example, to seek new ways of boiler feed water pump energy conservation. As China's 700,000 industrial boilers for the steam boiler about 2/3, so small steam boiler feed water pump energy-saving practical significance. Small steam boiler unit time refers to a small amount of the evaporation steam boiler, a steam boiler must be performed in accordance with the standards relevant state departments of production, manufacturing, testing pressure member to the film, after completion of the acceptance by the municipal supervision body inspection department, acceptance boiler boiler after passing the seal and issue a qualified procedures, formalities have qualified to go on sale. Refers to a pressure hot water boiler or body openings communicates with the atmosphere communicating pipe, in any case, the top of the boiler zero gauge pressure boilers, must also be sprayed in the apparent position of the furnace body "can not be confined to use" flag , pressure hot water boiler is not under pressure, while heating pipe system, with a pump with a valve, which can be used for bathroom, nursery, electroplating, chemical without high temperature does not exceed 90 ℃ places pressure hot water boiler pressure is prohibited to use, the non-opening communicating with the atmosphere communicating pipe or valve blockage or installation.
Pharmaceutical heating 10t boiler machine supplier estonia steam is how the selection of modern pharmaceutical companies to produce an important source of power. Main steam as a heat transfer medium, are widely used in heating and heating. Chinese medicine and its preparation extraction, concentration, dissolution, drying, sterilization, disinfection, heating, humidification, etc. should be widely applied. 1. How to choose type of boiler meet the technical requirements of the pharmaceutical production process, is an important factor affecting the normal operation of the modern pharmaceutical companies. Pharmaceutical companies not only need to be heated in the production process, also need to provide heating for the air-conditioning equipment. Clean air-conditioning systems not only need heating in winter, but also to raise the temperature of the air conditioning units in the summer after cooling, cooling and dehumidification, temperature and humidity to ensure a clean area. Major pharmaceutical companies for use in process heating, sterilization, washing, in addition to air conditioning, refrigeration, heating and the like.
Chongyang County, Hubei Province since the second half of 2015 to carry out the work out of small coal-fired 10t boiler machine supplier estonias, non-New 20 tons of steam / hour and below the coal-fired boilers, the full implementation of small coal-fired boilers out of work, with environmental protection, Development and Reform Commission, by letter and other related sector wages, work to strengthen the efforts to promote thorough investigation of strict control to ensure that the county's non-compliance of small coal-fired boilers have all been eliminated remediation. In the specified date (June 30, 2017) completed the small coal-fired boilers out of the task before. Up to now, Chongyang County is not a new coal-fired boilers.
It is understood that, recently, joint quality supervision department of Chongyang County People's Government of Hubei Province, a special selection of personnel to carry out "looking back" activities for the phasing out small coal-fired boilers, special personnel division of responsibilities is based on special teams, focus on examination paper, under chemicals, wine, agriculture, and several other sectors and enterprises of boiler equipment, non-small coal-fired boilers happen "resurgence" phenomenon.
Hot water 10t boiler machine supplier estonia circulating water system related issues: a hot water boiler circulating water system shall have the following to prevent the hot water circulation pump suddenly stopped, furnace water vapor and water hammer protection measures: 1 into the circulating pump, the a check valve provided with a bypass tube between the tube diameter should be similar and the manifold, and the bypass pipe cross-sectional area of not less than 1/2 of the cross sectional area of the main pipe; shall flow and a check valve flow direction of the pump in the same direction. 2. Set weight of formula inching valve in the inlet pipe section of the circulating pump, drain pipes which overpressure can open the access to the tank or drain. Second, hot water boiler circulating water system is also designed to meet the following requirements: 1 should be mounted on each cut-off valve or valve outlet pipe boiler, boiler feed water, the supply should be located on the water shut-off valve and check valve. 2. The hot water boiler is running in parallel, the control valve to be provided on each boiler inlet, so that the deviation of parallel boiler water temperature does not exceed 10 ℃. 3. The boiler water outlet pipe portion at the top and easy accumulation of gas should be installed and the exhaust gas collection means, not less than an exhaust valve DN20.4. Minimum system at low and recesses, should be arranged drainpipe and drain valve . The hot water system should be water pipe back to facilitate the installation position Qingtao decontamination, before and after the decontamination and closing the valve should the pressure gauge, and a small charge of 1 to 2 ratio of the bypass pipe. 6. The boiler should be provided with a plurality of trap and sump for hotspots, catchment trap and drain valve shall be arranged, thermometers, pressure gauges. Third, the hot water circulating pump of choice, shall meet the following requirements: a total flow pump shall be calculated: wherein G── pump flow (t / h); Q── total for the heat (kW); K1── net heat loss additional coefficients, k = 1.05 ~ 1.1; tg── water temperature (℃); th── return temperature (℃); G0── bypass flow rate (t / h), the bypass does not when G = 0.2 pump head should be calculated as follows: H = 1.1 (H1 + H2 + H3 + H4) H── wherein the pump head (m); H1── water boiler water pressure drop (m) provided by the boiler manufacturer, estimating 5.6MW or less forced circulation hot water boiler preferably H 8 ~ 15m =; H2── pressure loss in the boiler room of the water circulation system piping (m), according to the size of the system preferably H = 5 ~ 10m; H3── boiler room to the user the most unfavorable supply and return pipe pressure loss (m); pressure loss H4── most unfavorable internal system user (m). 3. The circulating pump flatter characteristic curve should be selected pump type, the parallel operation of the same pump model appropriate. 4. A pump circulating pump, the system should be able to withstand the hydrostatic pressure and increased pressure operation.
