Rotary blower: commissioning after installation
2021-03-25
Summary
After the rotary blower device, the trial operation is required. In fact, after the fan is repaired, it is also required to carry out an empty load test operation. What is the empty load test operation: during the test operation, time should be paid attention to the splashing condition of the lubricating oil on the pipe. if it is too much or too little, the oil quantity should be adjusted immediately.
rotary blowerAfter the installation, trial operation is required. In fact, after the fan is repaired, it is also required to carry out an empty load test operation. What is the empty load test operation: during the test operation, time should be paid attention to the splashing condition of the lubricating oil on the pipe. if it is too much or too little, the oil quantity should be adjusted immediately.
Carefully check whether there is any abnormal smell, smoke, bump or conflict. If there is, stop the machine in time to check. The radial amplitude of the bearing part should be less than 0.08mm, and the empty load operation should be carried out for about 30 minutes. If there is no return to normal phenomenon during the period, the load operation can be put into operation. If there is a return, you should check the discharge problem and then short the load until the normal stop.
After the empty load operation of the rotary blower is normal, the additional load cannot be adjusted at one time when the load operation is put into operation, and the load on the load shall be gradually and slowly adjusted as required until the additional load. Under the condition of normal exhaust port pressure, in order to prevent overload, it is necessary to pay attention to the pressure change of the intake port.
In order not to affect the stable operation of the rotary blower, the gas at the exhaust port is not allowed to flow back directly into the air inlet of the fan for a long time. When the normal operation of the fan, the inlet and exhaust port to listen to the valve demand all closed, also can not overload operation. When operating the rotary fan under additional working conditions, the surface temperature of the bearing should be lower than 85 ℃, the lubricating oil temperature in the oil tank should not be higher than 65 ℃, and the radial oscillation near the bearing position should not exceed 0.08mm. At the same time, attention should be paid to the splashing condition of the lubricating oil and the amount of oil. If there is a return, check it in time, and increase the amount of oil in time.
