As illustrated in FIG. 1, the lubricating oil L is mixed with the air A in a mixer (mixing block) 1, relays the distributors 2 and 3, and the lubricating oil is pressure-fed to a large number of oil supply portions 5 by an oil supply pipe 4. Supplied. When there are few refueling parts 5, no distributor is required, and when there are more refueling parts 5, more distributors are installed. In FIG. 1, only a part of the oil supply pipe distributor and the oil supply unit is shown. In this method, a relatively low-viscosity oil is used as the lubricating oil, and when pumped by air, it is transported along the wall surface of the oil supply pipe.

の信頼性を向上させることが重要である。The oil supply section is usually a large number of bearings and their seals. FIG. 2 is a simplified version of FIG. 1 showing an example in which the oil supply portion is a roller bearing. This lubricating oil pneumatic system generally supplies a small amount of oil continuously to the lubrication unit, so if a situation occurs where lubrication is stopped due to some accident, it will lead directly to a failure of the lubrication unit. It is important to improve the reliability of refueling.

6d is a bearing box, 6e is a lubricating oil-air supply port, 6f is an oil drain port, 6g is an oil drain pipe, and 6h is an oil drain receiver. In such a system, the detecting means 6j attached from the oil supply pipe 4a through the conduit 6i, or the oil discharge pipe 6g to the conduit 6i.
The refueling state is monitored by detecting the pressure of the air for pumping the lubricating oil by the detection means 6j or the like attached via the.

In a remarkably bad steelmaking facility, an abnormality in the detection means has occurred due to a poor installation environment of the detection means, which has hindered the oil supply abnormality monitoring and caused an increase in the cost of equipment maintenance.

FIG. 3 is a diagram showing the concept of the lubrication system of the present invention. In the system of the present invention, the lubricating oil L is mixed with the air A in the mixer 1, and relayed by the distributors 2 and 3 as shown in FIG. 1, or relayed by the distributor. Instead, the oil is supplied directly to a large number of oil supply portions 5 by oil supply pipes 4 that connect them. Figure 3
In FIG. 3, the distributor is omitted because it is not always necessary when the number of oil supply parts is small, and only part of the oil supply pipe is shown. When there are many refueling parts, as shown in FIG. 1, the plurality of refueling parts are piped in a branched manner from the mixer through the distributor. The lubricating oil is transferred from the mixer to the oil supply section by air along the pipe wall of the oil supply pipe.

位置に取り付けてあり、従来のような不便はない。Finally, the method for monitoring the lubrication system of the present invention will be briefly described. As shown in FIG. 1, in this lubricating system, lubricating oil is refueled by air along the pipe wall to a large number of refueling portions at the ends. In this state, the operator monitors the detector connected to the conduit group derived from the arbitrarily selected piping group in the middle of the piping and the oil supply section. This detector is centralized and mounted at a convenient location for monitoring, so there is no inconvenience as in the past.

ある。The detector has a structure as illustrated in FIGS. 5 and 6, and one of the inner and outer cylinders (inner cylinder in the example of FIGS. 5 and 6) is rotated or reciprocated, so that the conduit group is formed. By connecting each of the
The pressure of the air flowing in can be detected by the detection means connected to the discharge port, so that it can be known whether or not refueling is properly performed. The information on the refueling state may be viewed with a meter, or may be converted into an electronic form and used. If the refueling piping group is selected so as to correspond to each detector in advance, it is efficient to grasp the refueling state of the entire system.

ようになった。According to the present invention, in the lubricating oil pneumatic lubrication system, the detectors are connected to each detector collectively by a group of conduits from the middle of the oil supply pipe or from the oil supply destination. Therefore, unlike the conventional case, it is not necessary to detect the refueling states of a large number of refueling destinations at inconvenient positions in each individual refueling destination. As a result, the system installation cost and maintenance cost can be reduced, and the refueling status can be monitored easily and efficiently.
