Product details

XH-CM-G11 Medium pressure centrifugal fan

Product Introduction 
The XH-CM-G11 Medium pressure centrifugal fan is suitable for the air supply system of the 2~670t/h steam boiler in the thermal power plant and meets the requirements of the performance parameters of the high pressure head of the fluidized bed boiler. This series of fans can also be used for dust removal, mine ventilation and general ventilation systems.
The fan conveys air, and the induced fan conveys gas or gas containing impurity particles. When the impurity depth is less than 200mg/m3, it can be used for more than 4 years. It can also be used if it contains large impurity, but its service life will be shortened. The maximum operating temperature of the draft fan shall not exceed 250 ℃.

Performance and selection
1)The draft fan is made into a single suction form. There are 40 specifications for №8~29.5 each 20 machine numbers.
2)Each fan can be made into left or right rotation two forms.
3)The outlet position of the fan is expressed by the outlet angle of the housing.
4)Fan drive mode is D type (cantilever structure), the connection between motor and fan adopts elastic coupling and direct transmission.
5)Examples of full product names are as follows:
XH-CM-G11 18D 90 degrees right
XH-CM-G11 18 D 0 degree left
The pressure coefficient of the highest efficiency point is 10 times, 51 is the specific speed, 1 is the first design, and the other 18 is the impeller diameter of 1800mm.

XH-BI- 11 Boiler fan Fan structure
1)This series of fans adopts advanced technical achievements such as high strength wear-resistant impeller, oil-proof bearing box, joint axial adjusting door and so on.
2)Wide range of high-efficiency operating conditions, fan machine number arranged closely, easy to select high-efficiency operating point.
3)Adopt adjustable air inlet. The axial and radial clearance of the inlet and impeller are adjusted when the fan is installed.
4)High strength wear-resistant impeller. The impeller adopts the backward veneer blade to reduce the airflow impact, the stability is good, the motor is not easy to overload, and the service life of the fan is greatly prolonged. This type of fan has high pressure coefficient, low cycle speed and low noise, so it has good practicability.
5)Oil leakage proof bearing box. The lap oil jitter ring is used to throw the oil from the high speed rotating bearing into the inner wall of the bearing box, and the semi-open aluminum oil seal can increase the resistance along the axial direction to cut the partial thin oil back to the tank, except for the convenience of repair and prevention of friction accidents. The outer pressure plate is blocked by a small amount of thin oil, and the upper part of the bearing box is equipped with a ventilator to reduce the micro-positive pressure in the bearing box, ensuring no oil leakage and good dust-proof performance.
6)Joint type axial adjusting door. There are joint bearings at the fulcrum of the guide vane and the regulating rod of the regulating door. There is no "dead" point in the operation and adjustment process, so the adjustment is flexible and labor-saving, and the installation is reliable, which ensures that the actuator does not carry any load.
7)The fan is an integral or split assembly type. The transmission group of the series fan below 16D, the coupling cover and the motor are assembled on a complete base before leaving the factory; The housing, inlet and adjusting door are another component, the small type fan is assembled into two components when it leaves the factory, and the large model is decomposed and assembled into multiple components for transportation and installation.
8)The fan has cantilever structure, convenient arrangement, direct transmission of motor, uniform transfer of torque, reduction of vibration, and reliable operation of the fan.
9)The fan is convenient for installation and maintenance. The fan has two parts complete base shaft and transmission group, the housing has middle or vertical face, it is especially convenient to disassemble and assemble, the rotor can be suspended vertically, if the impeller is replaced only, it can also be disassembled in axial direction.
