Volume measurement type concentrated oil spray lubrication system

Abstract

The invention relates to a volume measurement type concentrated oil spray lubrication system which comprises an oil spray lubrication machine oil tank, an oil pump, an overflow valve and a plurality of combined nozzles, wherein each combined nozzle is provided with an electromagnetic valve used for controlling; the oil in the oil spray lubrication machine oil tank is conveyed into the plurality of combined nozzles by the oil pump through the overflow valve; the overflow valve is connected with the oil spray lubrication machine oil tank by a return pipe; a volumetric flow meter is also arranged behind the overflow valve, and is used for measuring the quantity of oil flowing into the combined nozzles; when the quantity of the oil sprayed by one combined nozzle reaches the set oil quantity, the oil is transferred into the next combined nozzle for lubricating a lubricating point. After the volume measurement type concentrated oil spray lubrication system is adopted, the pressure of all the nozzles is uniform.

Description

technical field [0001] The invention relates to the technical field of oil injection lubrication, in particular to a volume metering centralized oil injection lubrication system. Background technique [0002] Traditionally, open gears use three types of lubrication methods: oil pool lubrication, oil drop lubrication and manual lubrication at intervals. The oil pool lubrication method is to set a large oil pool at the bottom of the large gear, and when the gear teeth pass through the oil pool, excess oil is brought up to lubricate the gear surface. In this lubrication method, the problem that often occurs is that when the gear turns to the upper part, the excess lubricating oil will splash to other parts, resulting in leakage of lubricating oil and pollution of equipment, and at the same time, impurities will be mixed into the lubricating oil. Causes the lubricating oil pollution in the oil pool, seriously affects the lubricating effect. The dripping oil lubrication method ...

AI Technical Summary

Problems solved by technology

Since the lubricating oil of the overflow valve needs to return to the oil tank, an oil return pipe must be installed, and the diameter of the oil pipe should not be too small, otherwise it will form a "back pressure" on the overflow port of the overflow valve far away, thus affect its normal work

This solution is costly and complicated, so it is not suitable for use
