A paper of oil station pressure cooling system installed on the oil tank of the station, including pump, three-way valve, heat exchanger and the three-way valve, the oil pump, three-way valve, heat exchanger, three-way valve connected in sequence by the pipeline before and after valve, three-way valve through pipe connection. The oil pump is connected with the liquid level in the oil tank through the pipe, and the rear three-way valve extends to the oil tank through the pipe. The utility model through both ends in the heat exchanger set and set the guide pipe is connected with the three-way valve, two or three way valve, so that when the heat exchanger is abnormal, the oil pressure pipe, respectively through the guide pipe and return pipe flow back to the oil tank, without heat exchanger, the relevant technical personnel can be directly on the hot and heat exchanger for maintenance, without stopping treatment, avoid downtime caused economic losses, improve production efficiency, strong practicability, and has strong promotion significance.

造纸机油站分压冷却系统
本技术涉及一种分压冷却系统,尤其涉及一种用于造纸机油站分压冷却的系统。
技术介绍
目前,大型的造纸生产车间通常都设置有专用油站,用于为生产现场各设备提供液压油或润滑油,以维持设备的正常生产。然而,造纸设备在工作过程中,系统压力会有变化浮动,当压力过高时容易造成油泵供油过多,从而影响造纸设备的正常工作,需进行停机处理。由于造纸机为联动设备,设备停机则会造成较大的经济损失。
技术实现思路
为此,本技术的目的在于提供一种造纸机油站分压冷却系统,以解决目前油泵供油过多导致油压过大影响造纸机正常工作的问题。为实现上述目的,本技术主要采用以下技术方案为:一种造纸机油站分压冷却系统,装设于油站的油箱上,包括油泵、前三通阀、热交换器、后三通阀、输入管、输出管、分压管、导油管及回流管,所述输入管一端连接于油泵上,另一端延伸至油箱内,所述输出管一端连接于油泵上,另一端延伸至现场生产设备,所述分压管一端连接于输出管上,另一端连接于所述前三通阀上,所述前三通阀分别连接分压管、热交换器及导油管,所述后三通阀分别连接热交换器、导油管及回油管,所述回油管的另一端延伸至油箱内。导 ...
