Embodiment Construction

[0015] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0016] The fixed-point automatic refueling device for the shaft seat of the marine pump shown in the accompanying drawing includes an oil storage tank 1 , an oil guide pipe 2 , a bearing 3 and a shaft seat shell 4 . The axle seat shell 4 is a shell with a "D" shape in cross section, bearings and lubricating oil are placed in the inner cavity of the shell, the top layer is provided with a venting screw plug 4.1, and the bottom layer is provided with a draining screw plug 4.2. The oil guide pipe 2 is a "L" shaped pipe in a lying position, and the longer end is connected horizontally to the through hole at the bottom of the side of the shaft seat shell 4, and the upper inner hole wall of the horizontal oil guide pipe 2 and the shaft seat shell 4 set the upper limit of the oil level equal height. The short end of the oil guide pipe 2 is be...

Abstract

The invention discloses a fixed-point automatic oiling device of a marine pump shaft seat. The fixed-point automatic oiling device comprises an oil storage tank, an oil guiding pipe, a bearing and a shaft seat shell; the shaft seat shell is a shell with the D-shaped cross section, the bearing is placed in an inner cavity of the shell, lubricating oil is reserved in the inner cavity of the shell, aventilating screw plug is arranged on the top layer of the shell, and a discharging screw plug is arranged on the bottom layer of the shell; the oil guiding pipe is a lying L-shaped pipe, the longerend of the oil guiding pipe is transversely connected with a through hole in the bottom of the side face of the shaft seat shell, a pipe opening of the shorter end of the oil guiding pipe is bent upwards, and the vertical oil storage tank is hinged to one side edge of the pipe opening; and the oil storage tank is a cylindrical thin-walled container, the middle of the downward end of the vertical storage tank is provided with an oiling pipe penetrating through the interior and the exterior, and the downward oiling pipe is in butt joint with the upwards-bent pipe opening of the oil guiding pipeto constitute an oiling channel communicating with the oil storage tank and the shaft seat shell. The configured oil storage tank can store much more lubricating oil than the shaft seat shell, thus byconfiguring the fixed-point automatic oiling device, long-term fixed-point automatic oiling can be achieved, and the maintenance frequency and workload can be significantly decreased.

Description

technical field [0001] The invention belongs to the technical field of lubricating devices for shaft seats. Specifically, the invention relates to a shaft seat lubricating device, in particular to a fixed-point automatic oiling device for a shaft seat of a marine pump. Background technique [0002] The pump shaft seat is one of the basic structures of the centrifugal water pump, which directly bears the rotation of the pump shaft. The rotating quality of the pump shaft seat mainly depends on whether the internal lubrication structure is advanced, so the industry attaches great importance to the structural design of the pump shaft seat. In order to improve the running quality and maintenance-free period of the pump shaft seat of the centrifugal water pump, a certain oil storage space is usually reserved in the pump shaft seat in the prior art to increase the maintenance-free period. Due to the limitation of the structure, the reserved space in the pump shaft seat is very lim...
