1, hot water steamed boilers shutdown operations
Boiler outdoor detection means mounted matter detection device can acquire the outdoor temperature of the outdoor will transmit a signal to the control room steamed boilers, the boiler operator may then adjust the output power of the boiler, to heat buildings better. Detecting means attached to outdoor some caveats, the following is a specific description. Correctly installed outdoor temperature is the basis of the detected control function. The detector must be installed outside the building heating, 1/2 height of the wall, facing north or northwest direction, away from the local flue, doors, windows and direct sunlight. 1, the detector should be mounted on a smooth, flat wall 2, the maximum length between the detector and the control panel are an outdoor 50m3, any user connection cable conduit must be away from the power cord (230v) 4, the detector and the control panel can not have joints between the wires, if unavoidable, these joints must be well outside the probe seal mounting step 1, the detector opens the protection cover, is an adapter plate is rotated counterclockwise and the fixing hole. 2, find a fixed point as a template with a protective case. 3, removed the protective box, punching, use of the expansion plug. 4, two plugs using the supplied protective box fixed to the wall. 5, two wires connected to the connection plate, no need to determine positive and negative. 6, the cable seal tightening nut sleeve, close protection cover. Outdoor temperature controlled heating profile formed water temperature set point for the water temperature to maintain a certain level. Adjust the heating profile in different ways can be used to meet the heat output and room temperature. When the heating curve slope increases, the water temperature as the outdoor temperature decreases. Or, in other words, if the indoor temperature is not displayed correctly when the cold outdoors, is displayed correctly when the outdoor temperature is high, the heating curve slope must be re-adjusted. Increase slope: especially when the outdoor temperature is low when the water temperature increase. Reduce slope: especially when the outdoor temperature is high, reduce the water temperature. Set the heating chamber 20 is a graph of reference, such as the set point changes, it will automatically change the heating curve. Heating curve parallel displacement for changing the average flow temperature of the day, in other words, if the room temperature is too high or low, must be parallel displacement curve. The condensing boiler control automatically the heating curve to apply to the weather conditions, without resetting the heating curve slope, as long as can be on or off. To use this feature, the following points must be observed: 1, must be connected to the indoor sensor 2, 3 indoor setting change must be selected between 1 and 99, with reference to a thermostatic chamber without installing radiator valves, with reference to the sensor chamber is to install an indoor place (the installation of such a valve must be fully opened or closed if the sensor is used indoors, the compensation variable weather compensation function is activated by this parameter.
First of all, we must be clear what the phenomenon steamed boilers when full of water failure. 1, the water level is not visible or not, a high level alarm; 2, steam temperature decreases, main steam isolation valves and the turbine inlet valves visible white steam; 3, turbine or steam pipe occurs water impact; 4, water flow is not normal is greater than steam flow. Causes gas boiler filled with water following points. 1, water supply is automatically jump manually, resulting in abnormal increase of water supply; 2, or drum set on the safety valve steam header, resulting in up water or with water; 3, more evaporation boiler overload occurred priming.
The United States is our national enterprise, one of the world's top 500, with very bright glory on the world stage. US air-conditioning as a subsidiary branch, with a very large market competitiveness. 2016, Hubei US air-conditioning due to market demand to expand production lines, need to purchase steam steamed boilers to provide energy support for the new production line. After the boiler industry for a number of enterprises contrast, is determined to cooperate with the fast boiler, buy a whole 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
