In terms of ventilators, the main reason is to improve the efficiency of the fan by increasing the actual operating efficiency of the fan. The specific way is to develop a high-efficiency fan. Further study the theory of ternary flow and expand its application range. Expand the adjustment range to improve the efficiency of the fan under variable load conditions. The ternary flow theory is applied to develop a high-efficiency ternary impeller; the ternary flow theory is used in the design of the stationary element of the vane diffuser to improve the efficiency of the whole machine; the high-efficiency area of ​​the fan is enlarged to ensure that the fan can also operate efficiently under variable load conditions. For example, a small humpless axial fan that has been successfully developed. The main fan is selected correctly during the design. According to the use of the site, ensure the use of air volume and wind pressure, and select high-efficiency and low-noise fans based on this; select the adjustment scheme and energy-saving scheme according to the given working conditions and the changing working conditions in operation.
Reasonable choice of fan adjustment program. Speed ​​control energy-saving research has become the main direction of fan energy-saving research. The method of changing the impeller speed mainly adopts multi-speed or two-speed motor, frequency conversion speed regulation, cascade speed regulation, hydraulic coupler speed regulation, etc. Matching motor type selection speed control scheme. The frequency conversion speed regulation technology has the best energy saving scheme, and has the advantages of obvious energy saving, high precision control speed and torque, high speed driving, soft start, etc., and has been adopted by many mines. The ventilation network is reasonably arranged with ventilation network to reduce air leakage, increase ventilation section, reasonably distribute wind and air, clean and repair leaky roadway, increase ventilation section and reduce network resistance.
As the demand to control diesel engine emission increase, the in-cylinder optimisation technology is not satisfied with the standard request; In order to achieve the standard IV or higher standard level, it need to use SCR technology, SCR is mainly technology to reduce the emission of diesel engine emission.
Zhejiang Ailipu Tsingtech Exhaust Purification Technology Co.,Ltd is focus on innovation.production and sales of SCR equipment. during years, they developed general 1 and 2 air-assisted AdBlue Dosing pump and Injection Nozzle, general 1 non-air assisted AdBlue Dosing pump and Injection Nozzle
