Often the problem piezoelectric hot three pass industrial water boiler sale pump cavitation in the process often piezoelectric hot water boiler operation, the pump cavitation problems also one of the factors boiler fault, then how the hair phenomenon, when producing cause What kind of harm, and how to avoid, below, small series to do a simple analysis. 1. Cause cavitation generated:. A circulating pump installation height of the inlet static pressure does not meet the normal level, the pump is too small. b. When the boiler water temperature rose to a high temperature, before opening the pump is running, it will produce cavitation. c. Install the shut-off valve, to enhance the resistance of the tube, but also easily cause cavitation phenomena. 2. harm caused by cavitation: d the pump does not work properly. E. pump vibration and noise occur during running. F. affected piping material, it can be damaged. 3. Prevention measures: (1) ensure that the inlet pipe section rational design, to reduce drag pump inlet, to avoid the phenomenon of cavitation to some extent. (2) mixing apparatus may also be provided at the inlet of the pump, is introduced to the return portion, for hot and cold water are blended reduce the water temperature (water temperature should not exceed 75 degrees C.), thereby reducing the frequency of occurrence of cavitation, but may be avoid pump failure. (3) do not seal the expansion tank, while the suction pipe sections to tightly to prevent air suction. (4) at the same time be noted that, when the boiler temperature is low, that is, open the pump operation, avoid high temperature cavitation, resulting in damage to the pump.

It is reported that in the phase-out of coal-fired boiler reconstruction project, Jinan City, Shandong Province Finance Bureau has appropriated out of the transformation of coal-fired boilers municipal county area of ​​awards and subsidies 310 million yuan for the enterprises, units out of coal-fired boilers and special awards subsidy.

The allocation of financial awards complement funds, aims to accelerate the transformation of the city's coal-fired boilers out of work, to further improve air quality, according to the municipal government office "on accelerating the transformation of the city's coal-fired boilers out of work notice" (Ji Zheng Ban word [2017] 4) the requirements of the embodiment.

According to the municipal environmental protection department statistics, in 2017 the transformation range Jinan included in the elimination of 35 tons of steam and the following business units of coal-fired boilers 323 units, 1605 tons of steam coal-fired boiler units of 69, 189 tons of steam; the need for ultra-low emissions the transformation of more than 35 tons of steam coal-fired boilers of 94, 14 960 tons of steam. The issued rewards and subsidies, the Municipal Finance Bureau to take "the first disbursement, after the liquidation," the way out of the transformation of the inclusion of ultra-low emissions and transform the scope of coal-fired boilers in 2017 the implementation of full coverage, in accordance with the award criteria make a one-time pre dial counties and districts, counties and districts in the implementation of rehabilitation programs out of the boiler can award up early disbursement of funds of enterprises and units, to be enterprise, unit after the completion of the transformation carried out of funds liquidation.

Meanwhile, the Municipal Finance Bureau called on counties and district financial departments should closely cooperate with the environmental protection department, the main responsibility for the effective implementation of good out of the transformation of coal-fired boilers, will award up funds earmarked for municipal 35 tons of steam coal-fired boilers and substitution and elimination more than 35 tons of steam coal-fired boiler reconstruction project of ultra-low emissions (including troops out of coal-fired boiler replacement) cash incentives and subsidies, strengthen capital management, give full play to the financial capital efficiency.

Pet food factory steam boiler

Pet food factories provide a variety of food for pets, and boilers are needed in the production process. More and more people are starting to raise pets and use it as a spiritual comfort, which is very good for pets. This has also led to the rapid development of various pet food companies. This has promoted the development of pet food factories steam boilers from the side.

First, choose a good reputation in cooperation with boiler manufacturers, boiler manufacturers reputation is every sign, harvest a good reputation in the user groups manufacturers of boilers, must also be good quality. Whether exhaustive corrosion resistant, energy-saving aspects of life or doing good effect.
