Description
Technical Field
The invention relates to the field of oiling equipment, in particular to a special oiling pipe for an air cooling motor.
Background
The evaporative air cooler, also called closed cooling tower, is a long efficient energy-saving cooling device integrating water cooling, air cooling, heat transfer and mass transfer processes, and is widely applied to industries such as metallurgy, petrochemical industry, electric power, chemical industry and the like. The cooling water in the circulating water tank is conveyed to a water spraying system positioned above a process tube bundle by utilizing a circulating water pump, the cooling water is sprayed downwards to the surface of the tube bundle by the water spraying system, a layer of thin water film is formed on the surface of the tube bundle, and meanwhile, an axial flow fan sucks air to enable the air to transversely sweep the tube bundle which is obliquely arranged from the lower part of the tube bundle to the upper part of the tube bundle, so that the air flow is accelerated to enable the thin water film outside the tube bundle to evaporate rapidly, and the purposes of heat dissipation and temperature reduction of the tube bundle are achieved. The working process effectively meets the process production requirement, but is very unfavorable for the maintenance and the maintenance of the subsequent axial flow fans, the air outlet and the axial flow fans are arranged at the uppermost part of the whole set of air cooler, after the thin water film on the surface of the tube bundle is quickly vaporized, a large amount of water vapor with heat is discharged by the axial flow fans, so that the whole set of axial flow fan unit is always exposed to the high-temperature vapor environment, when an operator refuels and maintains the motor of the axial flow fan, the operator needs to probe the body into the movable radius of the fan, and the protection net is arranged, so that the operation difficulty is very high due to strong wind force and the water vapor with high temperature, and the high-temperature water vapor can influence the sight of the operator and even cause dyspnea under the action of strong wind force. The conventional solution is to stop maintenance or prolong the oil filling pipeline, although the method can achieve the purpose of filling oil in a safe area, because the maintenance period is longer (the bearing grease of a two-pole motor is filled for 1440 hours generally), the grease in the lengthening pipe of the running machine set can be liquefied and deteriorated under the moist high-temperature environment, the grease remained in the lengthening pipe of the standby machine set can be coagulated to block the oil filling pipe, the deteriorated grease can not be discharged during the oil filling maintenance, and the deteriorated grease can be directly filled into the bearing chamber of the motor together, so that the deterioration of the grease in the bearing chamber is accelerated, the bearing is damaged or the service life is shortened, and the normal production of the device is affected by the damage of an air cooling motor when serious damage exists; the motor is filled with lubricating grease in the running process to ensure that the lubricating grease is injected uniformly, so that the shutdown maintenance is firstly unfavorable for the oiling maintenance of the motor, secondly, the shutdown maintenance not only increases the process operation, but also is unfavorable for the production stability, for example, the production device has very high requirement on cooling in a high-temperature season, and the shutdown maintenance is basically not implemented at the moment.
