low pressure vacuum hot water boiler

Vacuum gas boiler can not be successful ignition, general root cause of several vacuum gas boiler using diesel fuel as the source, we need to run in the ignition process using vacuum gas boiler, sparking an unsuccessful run it is also the most general lying nest. Vacuum gas boiler in the adoption process, the most likely to cause ignition operation is not successful, produce vacuum gas boiler can not run normally, the authors introduce you to vacuum gas boiler can not be the root cause of several ignition general. Vacuum gas boiler ignition can not be the root cause of several general: First, the gas valve problems: pulse gas valve and controller such as those caused by unilateral lying nest, vacuum gas boiler is no way to work. Second, battery failure: If the battery should be mainly to check the batteries are not too old. Insufficient voltage, it makes vacuum gas boiler ignition operation is unsuccessful. Third, the failed pressure: inflow gas boiler vacuo clogging of the filter can not usually generate water circulation cleaner clearing on it. Fourth, miniature solenoid valves problems: vacuum gas boiler to run if the ignition when the ignition is running only to hear the sound of little miniature solenoid valves "despair" ci ci sound, perhaps aging-related injuries as miniature solenoid valves, miniature solenoid valves aging, will not by operation, when the ignition switch can be started at the point of a fire, but the flame and the speed i.e. confinement; determining whether miniature solenoid valves in the previous question has to be determined whether the usual gas valve operating module, if the problem can not operate miniature solenoid valves pull. Fifth, the ignition operation failure needle or needle sensors: a vacuum gas boiler ignition operation pin misalignment. You can change or correct needle placement of the ignition run; if failed induction of senescence, just to clean up the placement of good sense will be enough. Six, not the usual flue emissions. Vacuum gas boiler flue clogging, clog clearing flue flue too long, the formation is not correct. The instructions may form a double coaxial flue hot water unit. Seven water vapor collaboration assembly problems: vacuum gas boiler, water and gas valve cooperating aging or injured intimal flap will not push the operating state controlling means is weak; weak operating state controlling means bad.

The principle of a low pressure vacuum hot water boiler, hot water boiler works vacuum: a vacuum hot water boiler had already appeared in the early 1970s, first in the finished product is available in Japan. Development of domestic hot water boiler in a vacuum there are some manufacturers in the late 1980s, but due to technical issues, has not been promoted. Now that Japan has more mature models in China has also been a joint venture factory, the author is the choice of a dual-loop vacuum hot water boiler of the plant. The structure of vacuum hot water boiler, by the combustion chamber (furnace), water, vacuum vapor chamber, heat exchanger, heat medium consisting of water or the like. Vacuum state within the body, from the outside air, a sealed state is formed. HTM furnace and covered with water in a sealed tube and within the body, by the pressure of the negative pressure in the steam chamber is maintained below atmospheric pressure, when the heat medium water confined in the inner combustion heating, boiling up immediately, generating heat medium water steam of the same temperature. Steam generated in the machine during the ascent, the contact surface of the heat exchanger is disposed in the negative pressure of the steam chamber, since the water temperature in the heat exchanger is lower than the steam temperature, steam condenses on the heat exchanger surface and release a large heat of vaporization , the water heating heat exchanger, the condensed water under the action of the policy back to the heat medium water again. Accordingly, the heat medium water is constantly "boiling evaporated = = = heat medium condensed water" in a closed loop body. No need to supplement the condensed water, no air burning danger. Water heat exchanger is supplied to the user for heated sanitary hot water and air conditioning. To ensure the reliability of the vacuum hot water boiler operation, the three manufacturers to ensure: 1. In order to ensure a degree of vacuum inside the boiler, at the factory to create a rigorous inspection, the quasi gas leak detection, to ensure that the production process boiler airtight tank. To maintain the degree of vacuum, and to prevent the event, the plant is equipped with a standard suction pump. When the vacuum tank hot water boiler body, the heat medium water is heated to 90 ℃, according to the degree of vacuum exhaust pump automatic operation of the tank, not only the air out of the tank, also the presence of dissolved oxygen in water to remove the heat medium, to keep certain negative pressure, produced inside the tank will not corrode. 2. The heating medium water through a special manufacturing plant impurity, oxygen, water softening treatment, in the production of disposable infusion, can be recycled at runtime, without generally no special filling. I visited the plant in the design of the user survey, a Shanghai Electrical Machinery Plant, 87 years put into operation a vacuum hot water boiler, use a decade overheated media never raise water, which can still work normally. 3. The heat exchanger of the boiler with special requirements, using SUS444 stainless steel tube, which requires a special process during tube processing. The tubing is difficult to furring, high heat transfer efficiency, will not rust, the heat exchange tubes in a more than ordinary quality restrictions, flow rate.

How to make hot water boiler and water connections on the distinction between physical on specific types of boilers, in the following explanation will be involved in, this kind of boiler for hot water boiler, and this is a common and popular types of boilers , there is a wide range of applications, so we should take seriously and carry out, in order to make yourself have achieved, and at the same time, learning to have good results, and grasp its associated knowledge content. 1. pressure hot water boiler make up water in, and how to connect? Up in water pressure hot water boiler, which can be connected in a variety of ways. Generally, it will configure the expansion tank, therefore, can fill pipe into the tank from the upper portion of the tank, the fill pipe may be connected to the suction pipe of the circulation pump, it may also be a complement to the return water pipe of the opening and closing valve Behind. DETAILED select which mode is determined by the actual requirements and boilers. 2 large bath hot water boiler use, the tonnage of the boiler is determined by what? Hot water boiler large bath used, which is the actual tonnage of the boiler water to the decision, and, to avoid waste of boilers, boiler or can not meet the requirements to use the issue. Generally, use is 0.5 tons of hot water boiler or hot water boiler 2 tons. 3. hot water boilers and steam boilers, on how to distinguish between real? Which water quality requirements higher? Hot water boiler and a steam boiler distinction in kind, mainly to see that the following two aspects, one plate thickness, the plate thickness is less than the hot water boiler steam boiler plate thickness. Second, to see if there is steam separator drum boiler, the steam boiler is available, and vice versa for the hot water boiler. While on the water quality, the steam boiler is higher. 4. Vacuum hot water boiler, okay? Vacuum hot water boiler, hot water boiler which is a specific kind, and it is some of their own characteristics, so can not say okay this kind of hot water boiler, can only say that the circumstances under which the right to use this kind of boiler. In addition, we need to know is, well after the low pressure vacuum hot water boiler design, can not arbitrarily change the drawings, in case problems arise in the manufacture and use.
