The lubricating device has the characteristics of recycling lubricating oil as well as being high in lubrication utilization rate and good in lubrication effect.

The invention discloses a fire prevention test device for a lubricating oil pump with an external circulation of oil and gas. The lubricating oil pump and the burner are arranged in the combustion chamber. The exhaust device is connected to the combustion chamber and is used for exhausting the combustion chamber. When the oil pump works, the heating oil tank supplies oil to the oil supply level of the lubricating oil pump through the pipeline, and the oil supply level outlet and the oil return level outlet of the lubricating oil pump pump the lubricating oil back to the heating oil tank; the heating oil tank is also connected to another pipeline, which passes through the variable The oil pump pumps the lubricating oil from the heating oil tank to the oil-air mixing device. The oil-air mixing device mixes the lubricating oil and air to generate an oil-air mixture. The oil return stage of the lubricating oil pump is connected to the oil-air mixing device and pumps the oil-air mixture back to the heating oil tank. Carrying out the fire protection test through this equipment can not only realize the operation of the lubricating oil pump, but also simulate the actual working conditions of the lubricating oil pump installed on the engine to extract the oil-gas mixture, and can more simply and accurately guarantee the lubricating oil supplied to the oil-gas mixing device. oil volume.

The invention discloses an automatic conveyor belt cleaning device, which comprises a conveyor belt, an oil rubbing roller and a cylinder, the cylinder is connected with the oil rubbing roller through a control rod, an oil dirt sensor is arranged on the conveyor belt, and the The cylinder and the oil pollution sensor are respectively connected with the controller. The oil rubbing roller adopted by the invention can greatly reduce the damage to the conveyor belt, and at the same time deeply clean the oil stain on the surface of the conveyor belt. The invention can realize full-automatic detection operation and stop, and the oil rubbing roller is embedded in the way of loose buckle, and the replacement operation can be completed quickly. At the same time, the setting of automatic cleaning is adopted to carry out routine automatic cleaning to ensure that the oil quantity of the conveyor belt is at the minimum standard throughout the process. The invention is a general-purpose cleaning device, which can be widely used in various vertical and horizontal cutting, blanking and other production lines, saving a lot of manpower, reducing safety hazards, reducing downtime, improving product surface quality, and indirectly improving production efficiency and customer satisfaction.

The invention discloses an oil-gas separated-type balancing block which is internally provided with a channel, wherein the channel penetrates through two end surfaces of the balancing block and is communicated with the outer side wall of the balancing block. By adopting a compressor equipped with the balancing block provided by the invention can separate refrigerating machine oil from gas refrigerant in the operation process, thus the oil discharge amount of the compressor is reduced, not only can the amount of refrigerating machine oil in the shell of the compressor be ensured, the service life and dependance of the compressor are improved, but also the heat transfer effect and energy efficiency of an air conditioner can be improved.

A lubricating device for an internal combustion engine, including a connecting rod, a first oil passage, a second oil passage and a groove. The connecting rod includes a first surface provided on one end portion in the longitudinal direction of the connecting rod, and a bearing for supporting a pin shaft of a crankshaft or a pin shaft of a piston is fitted to the first surface. The first oil passage is configured to supply oil between the outer peripheral surface of the pin shaft and the inner peripheral surface of the bearing. The second oil passage is provided at one end and configured to inject oil. A groove is formed on the first surface or on the outer peripheral surface of the pin shaft, extends in the circumferential direction of the pin shaft, and collects oil. The second oil passage is connected to the groove.

Disclosed is a driving axle shell. The driving axle shell comprises an axle shell body, a main speed reducer shell (9) and axle tube parts (10). The axle shell body and the main speed reducer shell (9) are arranged in the middle, and the axle tube parts (10) are arranged at the two ends correspondingly. A half axle (4) can be installed in an inner hole of each axle tube part (10). The surface of the inner hole of each axle tube part (10) is provided with a spiral structure (8). Each spiral structure (8) is a single-head or multiple-head spiral flange or spiral groove. In addition, when the half axles (4) installed in the inner holes of the axle tube parts (10) rotate in order to drive a wheel hub (7) and a vehicle to go forwards, the direction of lubricating oil conveying through the spiral structures (8) points to one side of a main speed reducer (1). The structure is simple, the design is novel, and manufacturing is simple and convenient. The oil quantity in all cavities can be kept stable, sufficient lubrication of all components is ensured, and oil gas discharging and cooling effects on a wheel end mechanism (2) are particularly good. The service life of a driving axle system is effectively prolonged, and the driving axle shell can be suitable for all driving axles of which the wheel end mechanisms adopt oil lubrication.

The invention belongs to the internal field of internal combustion engines and provides a dry type oil pan oil supply device applicable to a large-inclination-angle diesel engine. According to the dry type oil pan oil supply device applicable to the large-inclination-angle diesel engine, two partition plates perpendicular to the bottom face of a dry type oil pan are arranged at the bottom of the dry type oil pan; an oil storing groove is formed between the two partition plates, and the two sides of the oil storing groove are each provided with an oil collecting groove of an open structure; an oil inlet pipe is arranged in each oil colleting groove; the flange ends of the oil inlet pipes are connected with an oil inlet of a two-stage parallel connection gear pump; one end of an oil outlet pipe arranged in the oil storing groove stretches out of the oil storing groove and is connected with an oil outlet of the two-stage parallel connection gear pump; the dry type oil pan oil supply device is further provided with an oil sucking pipe communicated with an engine oil pump of a diesel engine lubricating system; and the other end of the oil sucking pipe is connected with a suction filter located at the bottom of the oil storing groove in an inserted connection manner. The dry type oil pan oil supply device applicable to the large-inclination-angle diesel engine effectively solves the problem that under the conditions that the speed change and the inclination are large during turning of the diesel engine, normal lubrication of the diesel engine cannot be achieved, and the inclination angle of work of the diesel engine is greatly improved.
