SDS series tunnel jet fan
SDS series tunnel jet fan overview
Our company is the earliest manufacturer of jet fan for tunnel, has many years of production experience and a number of project performance, has accumulated a variety of different types of jet fan design and manufacturing experience, and according to the test of jet fans and the use of working conditions, established the jet fan technology database, so you can continue to improve the jet blower turbine blade manifold and size. The key parts of my company production of jet fan has been achieved in mould making. To determine the role of noise rectifier by forming hydraulic press 315 tons, to ensure that the wind has the best streamline structure. The key parts of the fan impeller is made of ZLG114 aluminum alloy by low pressure casting machine, J453A die-casting molding, molding after annealing and aging treatment and tensile test, after testing y ray flaw detection machine detection, through the high precision dynamic balancing machine balancing check, ensure that the fan can be long-term reliable operation. The company jet fan has won Shenzhen Fulong tunnel, Guizhou Huaxi tunnel, Shandong gold mining tunnel, Lanzhou military depot (explosion-proof fan), ventilation engineering of Xiamen Jimei bridge tunnel, tunnel, for the company brand wood a good market reputation, and has won the "quality, Shou credibility", "Zhejiang Province integrity business enterprise" and other honorary.
Jet fan is mainly used for longitudinal ventilation system of highway and railway tunnels, fan general suspension and tunnel top or sides, does not occupy the traffic area, does not need to be built. The construction cost low, ventilation in a very economic.
Fan works, from the given energy, produce higher thrust. A part of total amount of air flowing through the tunnel when the suction fan, impeller, export told jet. Based on the principle of shock transmission, high-speed airflow will transfer energy to the tunnel air, promote the tunnel air flow forward together. When the flow velocity attenuation to a certain value, the next group of fans to continue working, thus, the inhalation of fresh air from the entrance of the tunnel, eliminating pollution air from the outlet end.
I set the company many years of design, production experience of tunnel ventilation equipment, based on the original SDS type fan, in order to make the jet fan better and tunnel ventilation requirements are matched, and the new design 7 machine, and the original machine, improved design, SDS type I company jet the wind machine has the following characteristics:
1, a wide range of performance, more choice.
2, low energy consumption and high thrust.
3, special design. Impeller
4, a finely balanced, the fan running smoothly.
5, special motor, the fan can be long-term reliable operation, more than 20000 hours of operation.
6, T type bidirectional ventilation equipment, and wind speed are equal, only need to change the motor rotation, can realize the anti wind.
7, can be equipped with double speed motor, when natural ventilation is strong, low speed operation can reduce the operation cost.
8, easy to maintain.
Two, SDS series tunnel jet fan model description
SDS-90K-4P-D4 said the impeller diameter of 90cm, with 4 pole motor, fourth kinds of blade installation angle, one-way ventilation type SDS type jet fan.
Three, SDS series tunnel jet fan typical structure
The SDS type jet fan a package including: nozzle, muffler, rectifier, the fan section and the motor, as shown below.
1, the nozzle: Streamline nozzle improves the flow, the wind machine with high efficiency.
2, fan section ends with muffler. The silencer is two cylinder structure, or into the perforated plate, simply by the steel plate rolling. The middle filling special waterproofing sound-absorbing material
3, the fan section: with steel plate rolling, welding shell, flanges at the two ends of the muffler is conveniently connected with the fan section. Internally mounted motor and impeller, the impeller positioning flange to ensure consistent fan blade tip clearance. Airfoil blade by pressure casting aluminum alloy material.
4, fan section ends with muffler. The silencer is two cylinder structure, or into the perforated plate, simply by the steel plate rolling. The middle filling special waterproofing sound-absorbing material
5, the fan section: with steel plate rolling, welding shell, flanges at the two ends of the muffler is conveniently connected with the fan section. Internally mounted motor and impeller, the impeller positioning flange to ensure consistent fan blade tip clearance. Airfoil blade by pressure casting aluminum alloy material.
6, money, after the entire fluid: rectifying body similar to streamline model, efficiency improves the flow fan has the advantages of high.
7, the motor: sealing grease lubrication motor of special design, can be normal operation for 20000 hours, and meet the requirements of operation of high temperature fan. Rated voltage of 380V motor, frequency of the insulation class is F, protection class IP54. junction box and a fan casing body, can be easily connected with the user cable.
Four, SDS series tunnel jet fan technology
1) reliable data data in this chapter is based on years of practical experience, the aerodynamic field work and published.
2) K type jet fan the air when the air of 0.72~0.78 times. The air and air jet fan is equal to T.
3) SDS jet fan to -0.25~+50 ℃ temperature environment, can work reliably for a long time. Then the high temperature of 250 DEG C, continuous and reliable operation of 60min. The jet fan operating at high temperature should be repaired or replaced.
4) all parts after anticorrosion pretreatment, two coats of primer, a layer of paint. But for special circumstances, can be made of stainless steel, electroplating, etc.
5) noise sound level A to field, from the fan to export 10 meters, 45 degree angle measurement of the parameters listed in the table properties.
Five, series of jet fan performance parameters table

eight, SDS series jet fan installation, operation and maintenance
The installation quality of jet fan is particularly important, should print requirements embedded embedded parts, installation shall not bump and damage the fan, no welding on fan.
Install the fan, in addition to meet the requirement of tunnel boundary should ensure that the center line of the fan axis and the parallel tunnel. Otherwise, it will decrease the efficiency of fan.
The jet blower operation control according to CO concentration increased to decide on-off device or group, told or low speed. Jet fan is started, in order to reduce the impact on the power grid, by Taiwan to start, under the power of a fan is connected again that a Typhoon aircraft reaching the rated speed. Such as direct initiation interval of 120 seconds.
Jet fan is the reverse direction, such as impeller should be completely stopped, and then turn on the power supply.
Fan without special maintenance work. In order to maintain the cleanliness of fan, according to the pollution situation, regular cleaning air blower outer surface.
