Low Pressure Industrial Gas Fired Steam Boiler Price for Hotel
Car accessories types of complex processing, such as the interior wall Peng, floor, seats, instrument panels, sound systems, many processes required in a high temperature environment, the temperature becomes optional metrics wind Visteon hot water boiler. It is reported that Dongfeng Visteon existing boiler equipment can not reach the growing production needs, the introduction of fast boiler production of two parties often piezoelectric hot water boiler (CWDR1.8-95 / 70-II) in 2017.
The low pressure industrial fired steam boiler price for hotel can be divided into three kinds according to the fuel (electricity, oil, gas), such as electric steam boiler, oil steam boiler, gas steam boiler, etc. According to the structure can be divided into vertical steam boilers, horizontal steam boilers, small steam boilers are single, double-return vertical structure, large-scale steam boilers are mostly three-way horizontal structure. If according to the classification criteria above, there are a lot of steam boilers, take an ordinary fast-packed 4-ton steam boiler. Water is heated into steam in the drum and heat is emitted by fire in the furnace, which is the principle of the steam boiler. Steam The combustion part of a steam boiler consists of a chain grate and a drive device, together with a combustion chamber composed of a boiler rack on the grate frame. Surrounded by refractories. Coal from coal hopper, there are coal gate to control the thickness of coal seam while sealing the front of the air. The lower part of the combustion chamber is the place where the blast enters. This steam boiler has great resistance and needs forced blast. The cinder of a steam boiler, discharged from the back of the grate through Eagle's mouth iron and sent out of the furnace by a slag extractor. Steam boiler flue gas from the back of the boiler, by the steam boiler drum one-way smoke pipe forward, from the two-way smoke pipe back to the rear, then into the dust collector to separate ash, and then through the induced fan from the chimney exhaust Out. The above is the working principle of steam boiler, of course, the operation of steam boiler without other equipment, such as the induced fan not only undertake the task of exhaust flue gas, but also the steam boiler negative pressure operation necessary. There are also pressure vessels, thermometers, safety valves, pressure gauges, pumps, steam pumps, etc. All are essential for steam boiler work. Pump leak problem. The actual output flow rate of gear pump is smaller than that of theoretical flow due to the leakage of gear pump in the process of operation. The main leakage channel of gear pump is through the gap between the two sides of gear and the cover plate on both sides of the gear, which is 75% / 85% of the total leakage of the pump. Radial clearance leakage between gear top circle and inner hole of pump; clearance leakage through gear meshing. Because of the leakage of gear pump, the output pressure does not go, which affects the range of use of gear pump. In order to solve the problem of low output pressure of gear pump, the way of adding floating sleeve or elastic baffle on both sides of gear pump is adopted to reduce the leakage of gear pump and improve the output pressure of gear pump. Radial force imbalance problem. In the working process of the gear pump, the pressure on the outer circle of the gear is not equal, which results in the radial unbalance force at the shaft and bearing of the gear. This radial imbalance will accelerate the wear and tear of the bearing, reducing the bearing The service life also may cause the gear shaft to deform, causes the tooth top and the pump body inner hole friction, damages the pump body, causes the pump not to work normally. The common solution is as follows: (4) opening pressure balance slot on pump, leading high pressure oil to low pressure area, but it will increase pump leakage and affect pump volume efficiency; (2) reducing the size of the pressure chamber, reducing the pressure area acting on the gear teeth, and thus reducing the radial unbalanced force.
The following are the nine safety devices gas low pressure industrial fired steam boiler price for hotel. 1, water level monitoring: the original four water level is detected on the basis of a new fifth level detection, water level in cooperation with electronic detection devices, more comprehensive monitoring of boiler water level. 2, set the time: the user can set the starting time required to stop the boiler, free combination, convenient and flexible. 3, leakage protection: when the control system detects leakage electric heating elements, will automatically cut off power to prevent leakage fault occurs. 4, water protection: When the boiler water promptly cut off the gas burner control circuit to prevent the occurrence of dry damage the burner, while the controller sends water alarm indication. 5, power anomalies protection: Upon detection of a power failure, the boiler will stop running immediately. 6, the interlock overpressure protection: When the boiler pressure exceeds the user set value, the burner operation is prohibited and the alarm. 7, pressure controller, water level alarm, safety valve, low water level alarm and other multiple security. 8, a complete gas valve and protection system: providing a gas valve and accessories from whole filter, regulator and solenoid valve, ensuring safety gas. 9, real-time monitoring of flue gas: exhaust gas temperature of the boiler can be automatically monitored more easily grasp the combustion boiler.
How do I care after the low pressure industrial fired steam boiler price for hotel shutdown method Recently, many users did not know how to call maintenance shutdown after steam boilers, boiler maintenance is very simple in fact, today we explain the steam boiler and hot water boiler after shutdown maintenance. Since the cause of boiler failure or power shutdown required boiler, a steam boiler before travel should stop combustion boiler, the boiler slowly lowering the temperature until no pressure boiler, should pump before shutdown, induced draft fan and turn off the blower. After the maintenance shutdown home for boiler, furnace divided into external corrosion and home for the pot. Pot corrosion enjoying, enjoying their home for two kinds of wet and dry selected based on the length of shutdown time. When long-term disabled boiler, furnace should be paid close attention to external corrosion problems take care of themselves. First, the boiler shutdown cooling is necessary as far as possible completely eliminate fouling and ash grate heating surface of the upper, the lower portion of the furnace. Then have to adhere to certain natural ventilation flue. Under normal conditions, should be placed to dry moisture-proof agent in the furnace, flue. The dry quicklime as used, the furnace or the flue gas per cubic meter of ordinary should be placed about 3kg. After placing all the ventilation should be tightly closed doors. Lime powder to change after change. Such as boiler rooms in low-lying position, the air during shutdown severe flood tide, the method should be used regularly and placed a small fire to dry dry agent phase separation. If the boiler boiler long time, in order to thoroughly clean the soot topcoat red lead oil furnace or other metal surfaces in the anti-corrosion paint. As for the way home for corrosion inside the furnace shutdown, the shutdown Yaoan the length of time to be. Under normal circumstances, no more than one month shutdown of the available wet home for a month or more should take care of themselves dry. Dry to pay attention when enjoying the following questions: Do not dry agent in direct contact with the metal outer boiler, can be housed in a container such as an iron plate; dry agent after standing, for shutting the hole and the other hand hole cover, the vapor, the water pipe necessary to cut off valve; variant lime powder should be replaced. . Enjoying while wet, to pay attention to boiler water condensate is preferably used, followed by the available existing boiler water, demineralized water again; after adding the base, with a slow fire boiler water is heated to 80 [deg.] C the pressure rose to 100 0.2 when the 0.3MPa to maintain 2-3 hours, alkalinity boiler water circulated reach equilibrium, reduced pressure, then filled boiler water, a certain gauge, and continue to adhere to this pressure throughout the home for, alkalinity should Regular testing, decreases should be added at any time; in winter, wet enjoying pay attention to antifreeze, especially the local sewage channel and economizer; before re-use should release all the pot boiler lye, best prepared sump, in order to facilitate then. At the same time should be rinsed with clean water.
