Embodiment Construction

[0021] A hydraulic oil cooling system for a crusher, including a hydraulic station, a shell-and-tube heat exchanger, a delivery pump, pipelines, valves, and an exhaust port. The hydraulic station and the shell-and-tube heat exchanger are connected through pipelines, and the pipeline is set Control valve: use a shell-and-tube heat exchanger with a design pressure of 0.5Mpa, the tube side uses Ф19×2 304 seamless tube, and the shell side is Ф214×5 and the material is 20 (GB / T8163-2008) Seamless pipe; the shell side of the heat exchanger uses cooling water, and the tube side uses hydraulic oil. The vertical installation method is adopted. The lower end of the shell side is connected to the cooling water inlet, and the lower end of the tube side is connected to the hydraulic oil inlet (connected to the hydraulic fuel supply port of the station).

[0022] When working, the temperature of the cooling water is controlled to be 28°C; the flow rate of the cooling water is 5m³ / h; the pre...

Abstract

The invention discloses a hydraulic oil cooling system of a crusher, and belongs to the technical field of heat exchange. The hydraulic oil cooling system of the crusher comprises a hydraulic stationand a shell-and-tube heat exchanger, a conveying pump, pipelines, control valves and an exhaust port, wherein the hydraulic station and the shell-and-tube heat exchanger are connected through pipelines, and valves are arranged in the pipelines; and in the heat exchanger, hot oil in the tube pass and tap water of the shell pass through a temperature gradient between the tube pass and the shell pass, part of heat in the hydraulic oil is transferred to the cooling water, so that the purpose of reducing the temperature of the hydraulic oil is achieved, and the working stability and reliability ofthe crusher are improved.

Description

technical field [0001] The invention belongs to the technical field of industrial heat exchange, and in particular relates to a hydraulic oil cooling system of a crusher hydraulic system. Background technique [0002] After the hydraulic oil of the crusher has been working continuously for a period of time, its high-speed flowing fluid converts kinetic energy into heat energy in a specific space to directly heat the surrounding environment, making the temperature of the entire working space rise. The more intuitive performance is hydraulic pressure. The temperature of the working medium in direct contact with the oil rises sharply, showing that the various components of the crushing system are not working stably, and shutdowns often occur, which affects work efficiency and production effects. The conventional cooling system of the crusher is designed as water-cooled. By using an industrial water cooler, the industrial water cooler cools the water to the range of 0-5°C, and t...
