如何判讀羅茨鼓風機是超負荷和正常負荷運轉呢？
羅茨鼓風機在工作的過程中如何判斷他是超負荷和正常負荷呢？這對于羅茨鼓風機非常重要，下面Roots BlowerI'll take you through it.
一、鼓風機空負荷試運轉。
(1) Newly installed or overhauled fans should undergo an empty load test run.
(2) The concept of Roots blower no-load operation: put into operation under the condition that the inlet and outlet valves are all open.
(3) test run should pay attention to observe the lubricant splash situation is normal, such as too much or too little should be adjusted oil.
(4) There is no abnormal odor or smoke phenomenon and collision or friction sound, the radial amplitude of the bearing parts is not more than 0.08mm.
(5) No-load operation for about 30 minutes, such as the situation is normal that is put into operation with load. If found that the operation is not normal should be immediately checked, troubleshooting still need to be empty load operation.
二、鼓風機正常帶負荷運轉
(1) Adjust gradually and slowly as required to bring the load up to the rated load. It is not allowed to adjust to the rated load at one time.
(2) The so-called rated load refers to the static pressure difference between the intake and exhaust ports as indicated on the nameplate. If the pressure at the exhaust port is normal, attention must be paid to the pressure change at the intake port to avoid overloading.
3) Due to the characteristics of the Roots blower, it is not permitted to return the gas from the exhaust port directly into the air inlet of the blower for a long period of time, otherwise the safety of the machine will be affected.
(4) fan normal work, it is strictly prohibited to completely close the air inlet and outlet hear valve, also not allowed to overload operation.
(5) blower rated operating conditions, the surface temperature of the rolling bearings generally does not exceed 85 ℃, the oil temperature of the lubricating oil in the oil tank does not generally exceed 65 ℃, near the bearing parts of the radial vibration does not exceed 0.08mm.
6) Always pay attention to the splash condition of the lubricant and the position of the oil level.
