Pump operation, the bearing temperature limit is 75 ℃. If the bearing temperature exceeds 75 ℃, it is a fault caused by fever, serious, it will burn the bearings. Causes of bearing fever in the following areas:
â‘ lack of oil or grease bearing too much. Bearing box to add the right amount of grease, can play a lubricating effect, reducing frictional resistance, but also play a cooling role. The lack of oil will increase the bearing frictional resistance, resulting in bearing fever, temperature, but too much oil will increase frictional resistance, poor heat dissipation, the same will make the bearing heat, the temperature increases.
Remedy: Add grease or reduce the amount of grease. Practice has proved that the bearing plate generally filled with 1/3 ~ l / 2 grease is more appropriate.
â‘¡ There is no gap at the bearing cover. After the bearing end cap is installed, there should be a certain gap at one end. If there is no gap, when the pump is running due to heat and the spindle elongation, the two bearings will be stuck with the bearing cap, the bearing temperature.
Remedy: Add paper pad, adjust the gap.
â‘¢ too tight belt pull. Belt is too loose, easy to slip. So that the pump speed decreased, causing the lack of water or no water, but too tight belt pull, will increase the pressure of the pump axial force to increase frictional resistance, bearing fever, temperature rise.
Remedy: Proper adjustment of belt tightness.
Perilla seeds (Fructus Perillae) are the seeds of perilla, a plant of the Lamiaceae family. It can be used as seasoning to remove fishy smell, increase freshness and enhance flavor. At the same time, it has certain medicinal value, and has the effects of lowering Qi, clearing phlegm, moistening the lungs, and widening the intestines.
Efficacy and role:
1. Lower qi and resolve phlegm, relieve cough and relieve asthma: Perilla seeds can relieve qi stagnation, relieve asthma and eliminate phlegm, treat cough with excessive phlegm, and chest and diaphragm fullness and tightness. They are often used with tangerine peel, pinellia, magnolia bark, etc. to lower qi and resolve phlegm. . For those who suffer from food stagnation and fullness, it can be used together with white mustard seeds and radish seeds to digest food and resolve phlegm.
2. Loose intestines and relieve constipation: Perilla seeds contain a large amount of natural oils, which can lubricate the intestines and have a good therapeutic effect on intestinal dryness and constipation. They are often used with hemp seeds, almonds, and trichosanthes seeds.
