Construction of Product

LKT series ventilators are mainly consisted of scroll, impeller, frame bearing and shaft.
1. Scroll
The scroll is made of hot galvanizing steel sheet. Its side plate has an outline complying with aerodynamics. The scroll plat fixed to the side plates by means of “electric spot welding”.
On the side plate of the scroll there are a series of holes drilled in advance for riveting nuts to carry out installation according to air outlet direction needed by the customer.

2.Impeller
The impeller is made of high grade hot galvanizing steel sheet and is designed to a special configuration according to aerodynamics to make the efficiency highest and the noise lowest. The impeller is fixed on the middle disk plate and on the end ring with riveting grippers. The impeller has enough rigidity during continous rotation with maximum power. Before leaving factory, all impellers have passed all-round dynamic balance test according to the Company Standard which is higher level than National Standard.

3.Frame
The frames for type R ventilators are made of galvanized steel angle iron bars. Thecutting and bending of the frame parts, as well as the TOX connections, are formed with the use of molds to assure their high accuracy and the rigidity of the frames.

4.Bearing
LKT series ventilators are made of ball bearings of high quality, which are chosen according to the lowest noise produced. These bearingsare air-sealed, with preset lubricating oil, and of automatically alignment.The bearings are assembled on the support and vibration-proof rings arealso provided.

5.Shaft
The shafts are made of 40Cr of C45 carbon steel bars. The shafts are rough machined and then stress relieved before final machining. The shaft diameters are machined to very accurate tolerance levels and they are fully checked to assure precision fits, they are coated after assembly in order to provide corrosion resistance.

1.Direction of Rotation
Series ventilator can be devided into two direction of rotations, left-hand rotation (LG) and right hand rotation (RD); Viewing from end of motor outlet line,if the impeller rotates clockwise, it is called right hand ventilator; If the impellerrotates anti-clockwise, it is called left hand ventilator. The pulley can adjust its direction, left or right, therefore there is no limitation in directionality.

2.Direction of Air Outlet
According to Fig 1, LKT Series ventilator can be made in four air-outlet directions:0° ,90° ,180° , and 270°

3. Type of structure
According to Fig 2, LKT series ventilators can be divided into Category L . LK . R . RK Category L2 . R2.

Instructions

1.Prior to installation, all parts of the ventilator should be inspected. Greatand careful attention should be taken to shaft, bearings and main parts for checking. If there is some damage, recovery should be made, then to install again for use.

2.Check the internal space of the scroll and other casings, tools and other extra matters should not be left inside.

3.After installation, turn its impeller by hand or by means of lever to check for tightness or shock. Make sure that there is no such phenomenon over there, trial operation can be carried out.

4.Matching electric motor power of ventilator denotes internal power plus mechanical loss during driving and safety coefficient of electric motor capacity in special operating condition, it does not denote the power required during full opening of air outlet. Therefore no-load running of ventilator without any applied resistance including connecting pipelines on air-inlet or aor- outlet is strictly prohibited in order to avoid burning out of the motor caused by its operation at over rated power.

5.Soft connection between air pipe and ventilator air-outlet should be made.The joints should not be tightened too much.

6.Prior to official operation of ventilator, it is necessary to check the relating direction of both motor and ventilator for their coordination.

7.During ordering it is necessary to state the type of ventilator, speed, air volume, air pressure, direction of air outlet, rotating direction, type of electric motor and its specifications.
If the customer needs matching belts, pulley, electric motor, mountingframe and other parts and requirements, please state at that time
