Description

Heating device for lubrication station

Technical Field

The utility model relates to the technical field of lubrication systems, in particular to a heating device of a high-capacity lubrication station for conveying high-viscosity lubricating oil.

Background

Since the viscosity of the lubricating oil varies with temperature. The temperature of the lubricating oil increases, and the viscosity of the lubricating oil becomes small; conversely, the temperature of the lubricating oil decreases and the viscosity of the lubricating oil increases. The lubricating oil used in the lubricating stations matched with some heavy equipment has higher brand and higher viscosity. And when the ambient temperature is above 20 ℃, the oil supply of the lubrication station is normal. When the air temperature is reduced, especially in winter, the ambient temperature is close to about 0 ℃, the viscosity of the lubricating oil in the oil tank of the lubrication station is increased sharply, the fluidity of the lubricating oil is deteriorated, the flow resistance is increased, the suction capacity of the oil pump is reduced, the back pressure of the lubrication system is increased, the oil quantity output to the lubrication point of the lubrication pump is reduced greatly, and the lubrication system alarms.

In order to ensure that the lubrication system works normally at low temperature, the lubrication station generally adopts a heating device to heat the lubricating oil in the oil tank of the lubrication station to reduce the viscosity of the lubricating oil so as to meet the use requirement. The heating mode used at present is to set up the heater in the oil tank, heat the whole case oil in the oil tank to the suitable temperature to satisfy normal operating requirement.

The heating time of the lubricating oil is related to the oil storage quantity of the lubricating oil, the power of the heater, the temperature difference between the temperature before heating and the temperature to be reached, and the like. The ideal working state is that the equipment is ready to use, i.e. the lubricating oil can be heated to reach the proper working temperature quickly. Some heavy equipment requires large amounts of lubrication oil, and the correspondingly equipped lubrication station oil tanks can be up to thousands of liters in volume. Because the structural size of the oil tank and other factors such as power distribution, economy and the like are comprehensively considered, the power of the configured heater is insufficient to meet the requirement that lubricating oil in the oil tank can be quickly heated to reach the required working temperature, the lubricating system can reach the normal oil supply state only after heating for 15-30 minutes or longer; in order to ensure that the equipment can work normally when being started the next day, the lubrication station heater needs to work continuously for heat preservation after the equipment is stopped. The existing heating mode of the lubrication station has low heating speed, so that the working efficiency is affected; the shutdown heat preservation work increases energy consumption, and increases the security risk.
