1purpose

PCFThe series grate cooler fan is developed and designed based on the world's advanced fan manufacturing technology and the characteristics of grate coolers in the cement industry. Mainly used for forced ventilation of grate coolers in the cement industry. The working medium is air, and the temperature of the medium generally does not rise50℃The dust and hard particles contained in the medium shall not exceed150mg/m³

IIcharacteristic

PCFThe series of fans have the following characteristics:

High internal efficiency, wide high-efficiency zone, and can greatly save power, which is more suitable for other fans to save power10～30%.

The performance curve is flat and has good adjustability, avoiding the possibility of wheezing and ensuring safe operation.

Imported with pre rotating regulating door, which can be manually or automatically controlled to change the performance curve of the fan and ensure that the fan works at the optimal operating point.

The host adopts an integral base, and all components are adjusted and installed on the integral base before leaving the factory,

Customers can simplify the foundation design and construction work by using a horizontal foundation.

IIIstructure

The fan is mainly composed of an impeller, a casing, an air inlet, a transmission group, an integral bracket, and a regulating door.

leaf Wheel: composed of backward curved blades, curved wheel cover, flat disc welded together, and impeller

After dynamic balance correction, ensure smooth operation.

machine Shell: It is designed as a snail shaped shell with minimal flow loss.

Air inlet: Made into a convergent streamlined overall structure to provide optimal efficiency for the fan.

Transmission group: composed of main shaft, bearing box, coupling, etc. Mainly made of high-quality carbon steel, shaft

The bearing box adopts rolling bearings, lubricated with dry oil or thin oil, and adopts a new structure shaft end seal to achieve no leakage of lubricating oil and ensure a clean operating environment.

Integrated bracket: made of welded and processed steel sections and plates, with the fan main unit installed as a whole

On the bracket, the overall bracket is in planar contact with the foundation, simplifying the foundation design and construction for easy installation.

Adjustable door: circular petal shaped structure. By operating the handle with an electric actuator to change the blade angle

The inlet of the fan forms a pre swirl to change the performance of the fan with minimal loss, ensuring that the fan operates at its optimal state.

4type

PCFThe series of fans are designed as single suction type and are available in either forward or reverse rotation. Starting from the original motion

From the perspective of the machine, if the impeller rotates clockwise, it is called a clockwise cyclone machine, represented by "clockwise", and counterclockwise rotation is called a counterclockwise cyclone machine, represented by "counterclockwise". The outlet position of the fan is represented by the angle between the centerline of the air outlet of the casing and the horizontal plane, and can be made in both "forward" and "reverse" directions0⁰、45⁰、90⁰、135⁰、180⁰There are five forms in total, which can be specifically designed for other angles.

5Performance Requirement

For production volume1000t/d、2000t/d、3200t/d、400ot/dThe cement production line is equipped with a grate cooler

The specifications of the cooling fan are shown in the performance table (for reference). The performance parameters in the table refer to atmospheric pressure of101.3kPaThe intake temperature is32℃, intake density is1.154kg/m³The performance. If the usage conditions of the fan do not match the table, please convert according to the following formula:

P＝P₁×（B/101.3）×[（273＋32）/（273＋t）]（Pa）

N＝N₁×（B/101.3）×[（273＋32）/（273＋t）]（kW）

Q＝Q₁ （m³/h）

In addition to the above-mentioned products, we also undertake the design and manufacturing of cooling fans for grate coolers of other specifications.

Characteristics of cooling fan for high-pressure and low flow PCF grate cooler:

1. High internal efficiency, wide high-efficiency zone, can greatly save power, saving 10-30% of power compared to other fans.

2. The performance curve is flat, with a wide adjustment range and good adjustability and control. When adjusting, the vibration speed of the bearing box is not significant.

4. Advanced backward blade fans are selected to prevent motor overload.

5. Using patented technology RW cylindrical bearing box, the structure is simple, the operation is reliable, and the disassembly, assembly, and maintenance are convenient.

6. Adopting a short flow detection device, the detection accuracy is high and the footprint is reduced.

7. The use of a new type of double joint bearing axial adjustment door greatly reduces the static friction resistance torque, ensuring smooth and reliable operation.

The PCF series grate cooler cooling fan is a large-scale fan equipment used for forced ventilation cooling of grate coolers, which can be matched for cement production lines with a daily output of 1000-10000 tons.

Temperature: 0~80 ℃ Flow rate: 100~35003/h Pressure: 800~15600Pa
