1. Overview.
Rietschle vacuum pump is a kind of equipment widely used in chemical, pharmaceutical, food, environmental protection and other fields, with the characteristics of high vacuum and high efficiency. However, due to prolonged use, improper maintenance, etc., vacuum pumps may experience various failures. This article will introduce in detail the common faults and maintenance measures of Rietschle vacuum pumps.
2. Analysis of common faults and causes.
1.Insufficient vacuum: The cause of this failure may be leakage inside the pump body, deterioration of the pump oil, too much or too little pump oil, blockage of foreign matter in the pump chamber, etc.
2.Overheating of the pump body: It may be caused by too much pump oil, blocked or interrupted cooling water circuits, bearing wear, etc.
3.Abnormal noise: It may be caused by foreign matter blockage in the pump chamber, insufficient or deterioration of pump oil, bearing wear, loose pump body, etc.
4.Excessive vibration: It may be caused by loose pump body, weak pipe support, foreign body blockage in the pump chamber, etc.
5.Electrical faults: such as power switch tripping, motor overheating, fuse blowing, etc., may be caused by motor overload, circuit short circuit, etc.
3. Maintenance measures.
1.Maintenance measures for insufficient vacuum: first check whether there is leakage inside the pump body, and if leakage is found, it should be repaired;Secondly, check whether the pump oil is deteriorated, if it is found to be deteriorated, it should be replaced with new oil;Check again whether the pump oil volume is too much or too little, and if any abnormalities are found, adjustments should be madeFinally, check whether there is any foreign matter blockage in the pump chamber, and if foreign matter is found, it should be cleaned.
2.Maintenance measures for overheating of the pump body: first check whether the cooling water channel is unblocked, if it is found to be blocked or interrupted, it should be repaired;Secondly, check whether the pump oil volume is too much, if it is found to be too much, it should be adjusted;Check the bearing again for wear and replace it if it is found.
3.Maintenance measures for abnormal noise: First, check whether there is a foreign object in the pump chamber, and if it is found to be blocked, it should be cleaned upSecondly, check whether the pump oil quantity is insufficient or deteriorated, and if any abnormalities are found, it should be adjusted or replacedCheck the pump body again to see if it is loose, and if it is found to be loose, it should be tightened.
4.Maintenance measures for excessive vibration: first check whether the pump body is loose, if it is found to be loose, it should be tightened;Secondly, check whether the pipe support is firm, if it is found to be not firm, it should be reinforced;Check again whether there is any foreign matter blockage in the pump chamber, and if it is found, it should be cleaned.
5.Maintenance measures for electrical faults: first check whether the motor is overloaded, if overload is found, it should be step-downed;Secondly, check whether the circuit has a short circuit, if a short circuit is found, it should be repaired. In addition, for problems such as tripping of power switch, overheating of motor, and blown fuse, the power supply should be disconnected immediately for inspection and repair.
IV. Conclusions. Rietschle vacuum pump is an important industrial equipment, which is of great significance for the normal production and operation of enterprises. When the equipment fails, timely and effective maintenance measures are the key to ensure the normal operation of the equipment. This article makes a detailed analysis of the common faults and causes of Rietschle vacuum pumps, and proposes corresponding maintenance measures. It is hoped that it can help the relevant technicians to better maintain and use the equipment.
