Description
Technical field
The utility model relates to the device of the cooling of a kind of coal winning machine hydraulic oil and main oil pump bearing lubrication.
Background technique
Can produce heat when coal-mining machine hydraulic system normally works, can cause high oil temperature for a long time and make fluid rapid deterioration, oil viscosity reduces system effectiveness reduction simultaneously.Therefore keep oil temperature to be the necessary condition ensureing that hydraulic system normally works within the specific limits, generally all cooling unit must be housed.Cooling unit of the prior art is all too complicated, needs on different devices to design different oil-way systems, and function singleness, poor practicability, economical not.
Model utility content
For solving the problem, the utility model proposes a kind of structure simple, being convenient to install, the device of economical and practical and functional good coal winning machine hydraulic oil cooling and main oil pump bearing lubrication.
The technological scheme that the utility model adopts is: the device of a kind of coal winning machine hydraulic oil cooling and main oil pump bearing lubrication, comprise casing and be S-shapedly arranged in parallel two high pressure hoses in casing, one end of two high pressure hoses is connected with fuel inlet fitting and water supply connector respectively, the other end is connected with delivery connection and water output connector respectively, fuel inlet fitting is connected with the relief valve be located in coal winning machine, water supply connector is connected with coal winning machine cold water outlet, delivery connection is connected with transport pipe, the other end of transport pipe connects main bearing, the oil outlet of main bearing is communicated with coal winning machine fuel tank, water output connector is connected with the flexible pipe be communicated with water tank.
Further, the outlet port of described delivery connection and water output connector is equipped with one-way valve.
Further, the diameter of described two high pressure hoses is 10mm, and length is 5000mm.
Further, described fuel inlet fitting, water supply connector, delivery connection and water output connector are two type terminals.
Compared with prior art, it has following beneficial effect to the utility model:
The device overall structure of coal winning machine hydraulic oil cooling of the present utility model and main oil pump bearing lubrication is simple, reasonable, directly can install and use on all kinds of coal winning machine, very convenient; Lubricant oil centralized recovery in set relief valve release gear pump, flow to main bearing, play lubrication, hydraulic oil recycles, and prevents waste, and the hydraulic oil lubrication of cooling is better, simultaneously due to timely replenisher force feed, the advantages such as the life-span of main bearing is longer, has economical and practical, and function is strong and easy for installation.
