Abstract
The utility model relates to an oil cup with a constant liquid level, which belongs to the technical field of lubricating devices. The utility model solves the technical problem that an apparatus is damaged because of the dry friction of the bearing of a rotating machine due to oil starvation. The utility model is mainly composed of an oil cup, a cock with a beveled edge oil nozzle and an oil cup seat. According to the principle of pressure equilibrium, the utility model can automatically supplement the consumed oil quantity when a rotating machine works, which causes the oil surface in an oil chamber to keep a constant value. The utility model can stably supply the oil for a bearing, as long as the oil cup is periodically filled with the oil and certain oil is preserved in the oil cup.
Description
The utility model belongs to the lubricating fitting technical field.
Known to the claimant, the bearing of the dynamic and static part of rotating machinery (as the pump class) mostly is that turbine oil is lubricated.Rotating machinery in service continuously, owing to be subjected to thermal wear, seepage loss etc. reduce the oil in the grease chamber gradually, must check and replenish, to guarantee the normal operation of machinery.But in fact because a variety of causes, the oily moment oil-break or more long oil starvation in the grease chamber, Nobody Knows, thereby cause sound to burn out a bearing in friction, and the accident of damage equipment frequently takes place.
The purpose of this utility model provides a kind of constant level lubricating cup, it can refuel in the grease chamber continuously, and can keep liquid level constant in the grease chamber, whether transparent lubricating cup can clearly illustrate in the grease chamber oil starvation, thereby remind the operator to refuel, like this device damage accident with regard to having avoided causing because of oil starvation in good time.
The utility model is design like this: form a kind of constant level lubricating cup by lubricating cup 3, cock 4, oil cup seat 8 three parts.
Lubricating cup 3 usefulness transparent materials are made, and are carved with the metering sign on it, and top is rotary with oil cup cap 1, and for guaranteeing the two sealing, lid has a diaphragm seal 2 with the cup junction, and lubricating cup 3 bottoms link by screw thread and cock seat 5.
4 apertures are arranged at oil cup seat 8 tops, guarantee that the oil cup seat inner chamber communicates with outside atmosphere, and oil cup seat 8 is spun in the required lubricated bearing grease chamber 9 by screw thread in the horizontal direction.
Of the present utility modelly be: can in the grease chamber, refuel continuously, keep constant liquid level in the grease chamber, thereby avoided the device damage accident that causes because of oil starvation than point; Especially along with the raising of mechanical automation degree, the operation maintenance personnel reduce, and adorn the utility model on the rotating machinery, have guaranteed the operation of device security stable continuous, and it is significant.The utility model can be applicable in the grease chamber of all rotating machineries.Be installed on the bearing chamber of all kinds of water pumps, oil pump best results.
The contrast accompanying drawing describes in detail below.
Fig. 1 is the vertical profile schematic representation of constant level lubricating cup.
The grease chamber of 1-1 oil cup cap, 1-2 diaphragm seal, 1-3 lubricating cup, 1-4 cock, 1-5 cock seat, 1-6 aperture, 1-7 angle oil nozzle, 1-8 oil cup seat, 1-9 swivel bearing.
Its working procedure and principle are: the constant level lubricating cup that assembles is installed in the required lubricated bearing grease chamber.Screw off oil cup cap 1, cock 5 is slept in opening state, directly to grease chamber's 9 oilings, when oil overflows from 4 apertures 6 of oil cup seat 8, cut-out tap 5.Continue oiling, after the assigned scale of pasta to the transparent lubricating cup 3, stop oiling, screw oil cup cap, make cock 5 be in opening state again.This moment lubricating cup in the pasta pressure P
1Press H with the oil column of the height H that is higher than grease chamber's liquid level.It (is barometric pressure P that sum equals grease chamber's pressure
0(time, P
1+ H
0=P
0Pressure balance.After rotating machinery consumed parts of lubricating oil at work, pasta descended in the grease chamber 9, when the angle of reducing to angle oil nozzle 7 exposes pasta, because pasta pressure P in the lubricating cup
1＜P
0(barometric pressure), air enter lubricating cup top from the angle oil nozzle, make P
1Increase, enter grease chamber 9 again, make pasta rising in the grease chamber, until rising to the angle that floods oil nozzle 7 with entering oil cup seat 8 under the lubrication pressure in the lubricating cup.At this moment, pasta pressure P in the lubricating cup
1With oil column pressure H
0Sum and barometric pressure P
0Equate (P
1+ H
0=P
0), pressure balance stops oiling, so repeatedly circulation.After pasta drops to a certain degree in the lubricating cup 3, cock is closed, take off oil cup cap, add lubricant oil again, and then screw oil cup cap 1, open cock 5.As long as intermittent oiling, guaranteeing has a certain amount of oil in the lubricating cup, and 4 apertures 6 on the oil cup seat 8 keep unimpeded, and this constant level lubricating cup just can stably be supplied with bearing with oily, and can automatically replenish the oil mass of loss in the rotating machinery work, make that pasta keeps a constant value in the grease chamber 9.
