Automatic centralized circulating lubrication system for screw press

Abstract

The invention discloses an automatic centralized circulating lubrication system for a screw press. The automatic centralized circulating lubrication system for the screw press comprises an oil tank, ahydraulic motor oil pump, a multi-lubricating-oil-passage distributor, multi-passage oil injecting branch pipes, a main oil returning pipe, a lower oil returning branch pipe and an upper oil returning branch pipe, wherein the hydraulic motor oil pump is installed on the oil tank, the multi-lubricating-oil-passage distributor is connected with the hydraulic motor oil pump, the multi-passage oil injecting branch pipes are connected between the multi-lubricating-oil-passage distributor and a plurality of lubricating points, the main oil returning pipe is connected with the oil tank, the lower oil returning branch pipe which is used for collecting dripping lubricating oil is connected between the bottom of a lower cavity of a sliding block and the main oil returning pipe, and the upper oil returning branch pipe for collecting the dripping lubricating oil is connected between the bottom of an upper cavity of the sliding block and the main oil returning pipe. According to the automatic centralized circulating lubrication system for the screw press, automatic centralized lubrication is achieved, recycling is achieved, the energy is saved, the consumption is reduced, oil pollution does not exist, clean environment and environmental protection are achieved, the abrasion of moving parts is reduced, the operation of equipment is reliable, the service life of the equipment is long, the production cost is reduced, the maintenance time is reduced, fully lubrication is achieved, the operation cost is reduced, cooling is achieved, the operation of the equipment is safe, sealing is used for preventing corrosion and rusting, damping and cushioning are achieved, and the automatic centralized circulating lubrication system for the screw press is widely used in the lubrication of the screwpress.

Description

technical field [0001] The invention relates to an automatic centralized circulation lubricating system for a screw press, which can be widely used in the lubrication of the screw press. Background technique [0002] The relative movement between any parts will inevitably produce friction and wear, and lubrication is the most direct and effective way to reduce friction and wear. The traditional manual lubrication method is affected by factors such as its oiling method, maintenance specifications, and personnel responsibility, and has many shortcomings, such as ①The interval between grease injection is too long; Difficult heat dissipation and damage; too little grease, the friction pair is easily damaged due to dry friction; even some lubrication points are artificially omitted; ③The grease nipple is exposed, and dust and sand are easily brought in during oiling, which accelerates the wear of the friction pair. Manual lubrication is difficult to ensure continuous and effecti...

Problems solved by technology

The traditional manual lubrication method is affected by factors such as its oiling method, maintenance specifications, and personnel responsibility, and has many shortcomings, such as ①The interval between grease injection is too long; Difficult heat dissipation and damage; too little grease, the friction pair is easily damaged due to dry friction; even some lubrication points are artificially omitted; ③The grease nipple is exposed, and dust and sand are easily brought in during oiling, which accelerates the wear of the friction pair

Manual lubrication is difficult to ensure continuous and effective lubrication of the friction pair and screw pair. Many friction pairs of the equipment are in a dry friction state for a long time due to insufficient lubrication. What's more, the grease nipple is damaged or blocked and cannot be greased, which seriously affects the equipment. normal operation and life

[0003] At present, the lubrication of the screw, nut, and slider of the screw press is lubricated by oil immersion. The screw, nut, and slider are soaked in lubricating oil. The upper beam is a large oil tank, and each piece of equipment requires an average of high The strength of the lubricating oil is about 1000 kg, the energy consumption is high, and the lubricating oil will deteriorate after being stored in the equipment for a long time, and the sealing ring will be soaked in the oil for a long time to age and cause oil leakage, which seriously pollutes the environment
