Abstract
The utility model relates to the technical field of lubricating systems, in particular to a lubricating device of a negative-pressure oil line for a kneading and refining machine, which is provided with a main oil tank connected to a lubricating part through an oil line; the oil line is provided with a negative-pressure oil return system; the negative-pressure oil return system comprises a main motor, a gear oil pump driven by the main motor, a relief valve for adjusting working pressure and an oil outlet pipeline of the oil line, wherein the main motor is fixedly installed on the upper part of the main oil tank, the gear oil pump is installed on the oil outlet pipeline of the oil line, the relief valve is connected to pump-out end of the gear oil pump on the oil outlet pipeline of the oil line, and an oil return pump is installed on an oil return pipeline of the oil line and is driven by an oil return motor fixedly installed on the upper part of the main oil tank; and by adopting the negative-pressure oil return system, the obstinate oil leakage problem of a thin oil lubricating system is avoided.
Description
Technical field
The utility model relates to the lubricating system technical field, especially a kind of lubricating arrangement that is used for the negative pressure oil circuit of kneading conche.
Background technology
Lubricating system is mainly used on the rubber kneading conche, and kneading and refining that it is mainly used in reclaimed rubber are used to develop a circular economy.What wherein play a major role is roller, uses alloy chilled cast iron, surperficial hard wear resistant, and the working face of roller is level and smooth smooth roll.Need very big bearing capacity during roller work, carrying its structure is base bearing, the bearing capacity of base bearing commonly used is limited at present, and in the base bearing lubricant grease sealing property a little less than, the leakage of oil problem often appears, need replenish a large amount of lubricant greases when causing work, waste a large amount of lubricant greases.
The utility model content
The technical problems to be solved in the utility model is: for shortcoming and the deficiency that solves above-mentioned existence, provide a kind of lubricating arrangement of negative pressure oil circuit.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of lubricating arrangement of negative pressure oil circuit, have by oil circuit and be connected main fuel tank on the kneading conche lubricant housings bearing, oil circuit is provided with the negative pressure oil return system, the negative pressure oil return system comprises main motor, by main motor-driven gear oil pump, set up the overflow valve of operating pressure and the fuel-displaced pipeline of oil circuit, main motor is fixedly mounted on main fuel tank top, gear oil pump is installed on the fuel-displaced pipeline of oil circuit, the gear oil pump that overflow valve is connected on the fuel-displaced pipeline of oil circuit pumps end, the oil return oil pump is installed on the return line of oil circuit, the oil return oil pump has prevented the problem of a large amount of leakage of oils by being fixedly mounted on the oil return motor-driven on main fuel tank top.
The beneficial effects of the utility model are that the lubricating arrangement of a kind of negative pressure oil circuit of the present utility model adopts the negative pressure oil return system, stops the persistent ailment leakage of oil problem of oil lubricating system.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an overall structure schematic diagram of the present utility model.
Among the figure 1, oil circuit, 2, main fuel tank, 31, main motor, 32, gear oil pump, 33, overflow valve, 34, the oil return oil pump, 35, the oil return motor.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Fig. 1, the lubricating arrangement of a kind of negative pressure oil circuit shown in Figure 2, have by oil circuit 1 and be connected main fuel tank 2 on the kneading conche lubricant housings bearing, oil circuit 1 is provided with the negative pressure oil return system, the negative pressure oil return system comprises main motor 31, gear oil pump 32 by main motor 31 drivings, set up the overflow valve 33 of operating pressure and the fuel-displaced pipeline of oil circuit 1, main motor 31 is fixedly mounted on main fuel tank 2 tops, gear oil pump 32 is installed on the fuel-displaced pipeline of oil circuit 1, the gear oil pump 32 that overflow valve 33 is connected on the oil circuit 1 fuel-displaced pipeline pumps end, oil return oil pump 34 is installed on the return line of oil circuit 1, and oil return oil pump 34 drives by the oil return motor 35 that is fixedly mounted on main fuel tank 2 tops.
During work, main motor 31 driven gear oil pumps 32 are sent the lubricating oil in the main fuel tank 2 into the lubricant housings, simultaneously oil return motor 35 starts synchronously with main motor 31, drives oil return oil pumps 34 by oil return motor 35 and will be forces to extract out by bearing and the fluid that flows out the lubricant housings and handle utilization again.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
