Henan Henan boiler manufacturers boiler manufacturers of maintenance of the heat insulation layer and the soda boiler piping to be insulated to reduce heat loss. In the vertical boiler insulation cladding, and soda boiler shell type pipe line, after a period of operation, may come off the heat increased, the loss of both heat and increase the temperature of the boiler room, people sometimes burn. Thus, boiler manufacturers such as found in Henan insulation off, must be promptly repaired. Insulation and soda boiler tubes, generally divided into three layers, i.e. a heat insulating layer, the surface coating layer and the dressing layer. 1, the heat insulating material layer is mainly asbestos powder, vermiculite or perlite as raw materials, adding water mix into paste, when little heat pipe coated with or manufactured into a block shape suitable package outside the drum, the pipeline. The thickness of the insulating layer, according to the pipe diameter, the inner and outer cylindrical wall or tube wall temperature (i.e., steam and air temperature) may be. 2, with the general dressing layer 2x20x20mm barbed wire, a slight size specifications can also be used. 3, the surface coating layer is generally 50% to 50% incorporation of asbestos cement mixing add water and mix thoroughly, coated on the wire. Henan boiler manufacturers patch should be based insulation damage. In the case of partial loss can be partially removed at the drum, pipe wall cleaning brush, and then wrapped in the heat insulating layer, the surface coating layer and the dressing layer. The damage is not serious, the patch barbed wire (plus layer can), together with the surface coating layer. Steam piping is generally relatively high. Henan boiler manufacturers have spare word ladder repair, as with Zhuti, the bottom must have a non-slip facility, and there below a guardian to prevent Zhuti slide down. Prohibits a person climbing work.

1159, hot and cold air duct boiler and understand all kinds of applicable codes: boiler this important product website and keywords, I believe we will not feel strange, because the front of the product has been engaged in learning and understanding, and at the same time, so that we become familiar with and understand it, in turn, may be correct and reasonable use, and is expected to get the desired results. 1. gas boiler, which has its supporting devices, we must be clear? This kind of boiler gas boiler, which is on supporting devices, we need to know, there are mainly the following, are as follows: compensation device or system: automatically reduced when the water temperature is too high, too low water temperature rises automatically. Economizer: the condenser can be considered. Burner regulator: burning is mainly used for adjustment of the boiler in order to ensure good combustion. Exchanger: to increase the thermal efficiency of the boiler, so as to save energy for this purpose. 2. boiler, what is hot air and cool air duct channel? Road hot air boiler, which is specifically the case, it refers to the future after a warm-up channels, channels for hot air, and that part of the channel leading to the outside world preheater, it is cold Road. In addition, it flue, the flue gas flow passage means. Therefore, these three terms, should have a correct understanding, you can not go wrong.
Overpressure stop furnace and timely relief; low water level is not automatic replenishment, immediately replenishment manually; the (automatic or manual) stop switch transposed, and the relief after replenishment until normal reheating.
2, the control cabinet when overpressure occurs, phase, low water level, the high level alarm, press the mute button to check the cause of the malfunction and immediately removed; if the alarm is not more than 3 minutes in time, easy to burn bell.
3, in case when the phase indicated: A, to check whether the power supply phase. B, check the bell is burned out. C, check the contactor coil, a transformer, etc. is burned. After completion of the above problems troubleshooting timely replacement element, and the secondary fuse circuit, fault and inform the manufacturer in case of complex or repair guidance.
4, when the frequent replenishment, check whether the water supply pump check valve failure, fill the water tank upside down, shutdown should be promptly repaired or replaced.
5, regular (two weeks) to check the boiler water quality so that it meets the requirements, the need to frequently boiler blowdown.
6, on a regular basis (7-15 days) to check water level gauge scale and clean the electrode can be shutdown if necessary check.
