Description
技术领域technical field
本发明涉及一种加热型工业液压油制冷机用于设备热源的降温方法。The invention relates to a heating type industrial hydraulic oil refrigerator used for cooling the heat source of equipment.
背景技术Background technique
众所周知，工业液压系统油温最佳工作温度是在35~55摄氏度之间，一旦温度升高到60摄氏度以上，液压系统的性能将大幅度的下降，机器设备故障不断出现，造成设备的稳定性严重下降，无法保证机器设备的正常运行。尤其是在夏季，空气温度较高，液压油的温度持续升高会使得机器设备常常处于停机状态。因此寻求一种对液压油冷却效果好，操作方便，能耗较低的加热型工业液压油制冷机用于设备热源的降温方法尤为重要。As we all know, the best working temperature of industrial hydraulic system oil temperature is between 35 and 55 degrees Celsius. Once the temperature rises above 60 degrees Celsius, the performance of the hydraulic system will be greatly reduced, and the failure of machinery and equipment will continue to appear, resulting in the stability of the equipment. Serious decline, unable to guarantee the normal operation of machinery and equipment. Especially in summer, the air temperature is high, and the temperature of the hydraulic oil continues to rise, which will make the machinery and equipment often shut down. Therefore, it is particularly important to seek a heating-type industrial hydraulic oil refrigerator with good hydraulic oil cooling effect, convenient operation and low energy consumption for cooling the heat source of the equipment.
发明内容Contents of the invention
本发明的目的在于克服上述不足，提供一种对液压油冷却效果好，操作方便，能耗较低的加热型工业液压油制冷机用于设备热源的降温方法。The object of the present invention is to overcome the above disadvantages and provide a heating-type industrial hydraulic oil refrigerator with good cooling effect on hydraulic oil, convenient operation and low energy consumption for cooling the heat source of equipment.
本发明的目的是这样实现的：The purpose of the present invention is achieved like this:
一种加热型工业液压油制冷机用于设备热源的降温方法，所述加热型工业液压油制冷机包括一根液压油输送管路，该液压油输送管路上从液压油进油口至液压油出油口之间依次设置有液压油输送管路输送泵和换热装置，所述换热装置的冷却出口至冷却进口之间的冷却管路上依次设置有气液分离器、压缩机、冷凝器、储液器、干燥过滤器、冷却管路电磁阀以及节流装置，压缩机至冷凝器之间的冷却管路和节流装置至换热装置之间的冷却管路之间设置有一个冷却管路旁通阀，所述换热装置两端的液压油输送管路上并联设置有一根液压油旁通管路，所述液压油旁通管路上设置有液压油旁通阀，所述液压油输送管路上设置有液压油输送管路温度传感器；A heating-type industrial hydraulic oil refrigerator is used to cool down the heat source of equipment. The heating-type industrial hydraulic oil refrigerator includes a hydraulic oil delivery pipeline, and the hydraulic oil delivery pipeline is from the hydraulic oil inlet to the hydraulic oil A hydraulic oil delivery pipeline delivery pump and a heat exchange device are arranged in sequence between the oil outlets, and a gas-liquid separator, a compressor, and a condenser are arranged in sequence on the cooling pipeline between the cooling outlet of the heat exchange device and the cooling inlet. , liquid receiver, dry filter, cooling pipeline solenoid valve and throttling device, a cooling pipeline is set between the cooling pipeline between the compressor and the condenser and the cooling pipeline between the throttling device and the heat exchange device A pipeline bypass valve, a hydraulic oil bypass pipeline is arranged in parallel on the hydraulic oil delivery pipeline at both ends of the heat exchange device, a hydraulic oil bypass valve is set on the hydraulic oil bypass pipeline, and the hydraulic oil delivery pipeline The pipeline is equipped with a hydraulic oil delivery pipeline temperature sensor;
加热型工业液压油制冷机用于设备热源的降温方法包括以下步骤：The cooling method of the heating type industrial hydraulic oil refrigerator for the heat source of the equipment includes the following steps:
步骤一、连接设备热源和加热型工业液压油制冷机；Step 1. Connect the heat source of the equipment and the heating type industrial hydraulic oil refrigerator;
加热型工业液压油制冷机的液压油输送管路的液压油进油口和液压油出油口分别通过液压油进油口软管和液压油出油口软管连接设备热源的液压油排油管路和液压油回油管路；The hydraulic oil inlet and hydraulic oil outlet of the hydraulic oil delivery pipeline of the heating type industrial hydraulic oil refrigerator are respectively connected to the hydraulic oil discharge pipe of the heat source of the equipment through the hydraulic oil inlet hose and the hydraulic oil outlet hose road and hydraulic oil return line;
步骤二、设备热源开始运行后，储油箱第二个液压油室的液压油经过储油箱出油管路供给设备发热装置，设备发热装置内的液压油通过储油箱进油管路排至储油箱的第一个液压油室，第一个液压油室的液压油依次经过液压油排油管路、液压油进油口软管、液压油输送管路、液压油出油口软管以及液压油回油管路回至储油箱的第二个液压油室；Step 2: After the heat source of the equipment starts to operate, the hydraulic oil in the second hydraulic oil chamber of the oil storage tank is supplied to the heating device of the equipment through the oil outlet pipeline of the oil storage tank, and the hydraulic oil in the heating device of the equipment is discharged to the first part of the oil storage tank through the oil inlet pipeline of the oil storage tank. One hydraulic oil chamber, the hydraulic oil in the first hydraulic oil chamber passes through the hydraulic oil discharge pipeline, the hydraulic oil inlet hose, the hydraulic oil delivery pipeline, the hydraulic oil outlet hose and the hydraulic oil return pipeline in sequence Return to the second hydraulic oil chamber of the oil storage tank;
设备热源运行初期，液压油温度低，液压油在液压油输送管路的流动直接从液压油旁通管路流动，液压油不经过换热装置进行冷却，设备发热装置运行一段时间会导致其内部的液压油温度也随之升高，因此设备发热装置排出至储油箱内的第一个液压油室的液压油温度也升高，储油箱温度传感器或者液压油输送管路温度传感器检测到液压油的温度达到一定高温，液压油旁通阀关闭，换热装置启动，液压油经过换热装置进行冷却；In the early stage of equipment heat source operation, the temperature of the hydraulic oil is low, and the flow of hydraulic oil in the hydraulic oil delivery pipeline directly flows from the hydraulic oil bypass pipeline. The hydraulic oil does not go through the heat exchange device for cooling. The temperature of the hydraulic oil also increases accordingly, so the temperature of the hydraulic oil discharged from the heating device of the equipment to the first hydraulic oil chamber in the oil storage tank also increases. The temperature sensor of the oil storage tank or the temperature sensor of the hydraulic oil delivery pipeline detects that the hydraulic oil When the temperature reaches a certain high temperature, the hydraulic oil bypass valve is closed, the heat exchange device is activated, and the hydraulic oil is cooled by the heat exchange device;
或者设备热源运行初期，液压油旁通阀关闭，换热装置关闭，热管式加热器启动从而提高提高液压油输送管路内液压油的温度，直至储油箱温度传感器或者液压油输送管路温度传感器检测到液压油的温度达到一定高温，热管式加热器关闭，换热装置启动，液压油经过换热装置进行冷却；Or at the initial stage of equipment heat source operation, the hydraulic oil bypass valve is closed, the heat exchange device is closed, and the heat pipe heater is started to increase the temperature of the hydraulic oil in the hydraulic oil delivery pipeline until the temperature sensor of the oil storage tank or the temperature sensor of the hydraulic oil delivery pipeline It is detected that the temperature of the hydraulic oil reaches a certain high temperature, the heat pipe heater is turned off, the heat exchange device is activated, and the hydraulic oil is cooled by the heat exchange device;
液压油经过换热装置进行冷却，冷却管路上的冷却管路电磁阀启动，冷却管路开始运作，冷却管路在换热装置处与液压油输送管路内的高温液压油进行热交换，对高温液压油进行冷却，使得被换热装置冷却的低温液压油经过液压油输送管路为重新回至储油箱的第二个液压油室继续供给设备发热装置。The hydraulic oil is cooled by the heat exchange device, the cooling pipeline solenoid valve on the cooling pipeline is activated, and the cooling pipeline starts to operate. The cooling pipeline performs heat exchange with the high-temperature hydraulic oil in the hydraulic oil delivery pipeline at the heat exchange device, and The high-temperature hydraulic oil is cooled, so that the low-temperature hydraulic oil cooled by the heat exchange device passes through the hydraulic oil delivery pipeline and returns to the second hydraulic oil chamber of the oil storage tank to continue to supply the heating device of the equipment.
其中冷却管路的工作原理是：The working principle of the cooling pipeline is:
从压缩机出来的高温高压气体经过冷凝器后变为低温高压气液混合体，然后经过储液器进行气液分离形成低温高压液体，然后经过干燥过滤器进行除水除杂，然后经过节流装置形成低温低压液体，低温低压液体在换热装置内经过换热形成低温低压气液混合体，低温低压气液混合体经过气液分离器进行气液分离形成低温低压气体，然后低温低压气体再经过压缩机进行压缩形成高温高压气体，往复上述的循环，从而冷却管路对经过换热装置的液压油输送管路的液压油进行冷却。其中冷却管路中的冷却管路旁通阀的作用是在冷却管路中的压力持续升高达到一定值时，冷却管路旁通阀打开进行泄压对冷却管路起到保护作用；冷却管路电磁阀的作用是在冷却管路不运作时，放置冷却管路电磁阀前方的液体向后流至压缩机内，使得压缩机损坏，起到保护作用。The high-temperature and high-pressure gas from the compressor turns into a low-temperature and high-pressure gas-liquid mixture after passing through the condenser, and then passes through the liquid receiver for gas-liquid separation to form a low-temperature and high-pressure liquid, then passes through a dry filter to remove water and impurities, and then passes through throttling The device forms a low-temperature and low-pressure liquid. The low-temperature and low-pressure liquid undergoes heat exchange in the heat exchange device to form a low-temperature and low-pressure gas-liquid mixture. Compressed by the compressor to form high-temperature and high-pressure gas, and reciprocate the above cycle, so that the cooling pipeline cools the hydraulic oil passing through the hydraulic oil delivery pipeline of the heat exchange device. The cooling pipeline bypass valve in the cooling pipeline is used to protect the cooling pipeline by opening the cooling pipeline bypass valve to release pressure when the pressure in the cooling pipeline continues to rise to a certain value; The function of the pipeline solenoid valve is to prevent the liquid in front of the cooling pipeline solenoid valve from flowing backward into the compressor when the cooling pipeline is not in operation, so as to damage the compressor and play a protective role.
与现有技术相比，本发明的有益效果是：Compared with prior art, the beneficial effect of the present invention is:
本发明加热型工业液压油制冷机用于设备热源的降温方法具有对液压油冷却效果好，操作方便，能耗较低的优点。The heating-type industrial hydraulic oil refrigerator of the present invention is used in the cooling method of the heat source of equipment, and has the advantages of good hydraulic oil cooling effect, convenient operation and low energy consumption.

一种加热型工业液压油制冷机用于设备热源的降温方法：A heating-type industrial hydraulic oil refrigerator is used to cool down the heat source of equipment:
步骤一、连接设备热源900和加热型工业液压油制冷机；Step 1. Connect the equipment heat source 900 and the heating type industrial hydraulic oil refrigerator;
加热型工业液压油制冷机的液压油输送管路100的液压油进油口和液压油出油口分别通过液压油进油口软管和液压油出油口软管连接设备热源900的液压油排油管路904和液压油回油管路907；The hydraulic oil inlet and hydraulic oil outlet of the hydraulic oil delivery pipeline 100 of the heating type industrial hydraulic oil refrigerator are respectively connected to the hydraulic oil of the equipment heat source 900 through the hydraulic oil inlet hose and the hydraulic oil outlet hose Oil discharge pipeline 904 and hydraulic oil return pipeline 907;
步骤二、设备热源900开始运行后，储油箱902第二个液压油室的液压油经过储油箱出油管路905供给设备发热装置901，设备发热装置901内的液压油通过储油箱进油管路903排至储油箱902的第一个液压油室，第一个液压油室的液压油依次经过液压油排油管路904、液压油进油口软管、液压油输送管路100、液压油出油口软管以及液压油回油管路907回至储油箱902的第二个液压油室；Step 2: After the equipment heat source 900 starts to operate, the hydraulic oil in the second hydraulic oil chamber of the oil storage tank 902 is supplied to the equipment heating device 901 through the oil storage tank outlet pipeline 905, and the hydraulic oil in the equipment heating device 901 passes through the oil storage tank oil inlet pipeline 903 Drain to the first hydraulic oil chamber of the oil storage tank 902, and the hydraulic oil in the first hydraulic oil chamber passes through the hydraulic oil discharge pipeline 904, the hydraulic oil inlet hose, the hydraulic oil delivery pipeline 100, and the hydraulic oil outlet The mouth hose and the hydraulic oil return line 907 return to the second hydraulic oil chamber of the oil storage tank 902;
设备热源900运行初期，液压油温度低，液压油在液压油输送管路100的流动直接从液压油旁通管路300流动，液压油不经过换热装置102进行冷却；At the initial stage of operation of the heat source 900 of the equipment, the temperature of the hydraulic oil is low, and the hydraulic oil flows in the hydraulic oil delivery pipeline 100 directly from the hydraulic oil bypass pipeline 300, and the hydraulic oil does not pass through the heat exchange device 102 for cooling;
设备发热装置901运行一段时间会导致其内部的液压油温度也随之升高，因此设备发热装置901排出至储油箱902内的第一个液压油室的液压油温度也升高，储油箱温度传感器908或者液压油输送管路温度传感器103检测到液压油的温度达到一定高温（超过60摄氏度），液压油旁通阀301关闭，液压油经过换热装置102进行冷却，此时冷却管路200上的冷却管路电磁阀206启动，冷却管路200开始运作，冷却管路200在换热装置102处与液压油输送管路100内的高温液压油进行热交换，对高温液压油进行冷却，使得被换热装置102冷却的低温液压油经过液压油输送管路100为重新回至储油箱902的第二个液压油室继续供给设备发热装置901。The operation of the equipment heating device 901 for a period of time will cause the temperature of the internal hydraulic oil to rise accordingly, so the temperature of the hydraulic oil discharged from the equipment heating device 901 to the first hydraulic oil chamber in the oil storage tank 902 also rises, and the temperature of the oil storage tank The sensor 908 or the hydraulic oil delivery pipeline temperature sensor 103 detects that the temperature of the hydraulic oil reaches a certain high temperature (over 60 degrees Celsius), the hydraulic oil bypass valve 301 is closed, and the hydraulic oil is cooled by the heat exchange device 102. At this time, the cooling pipeline 200 The solenoid valve 206 of the cooling pipeline above is activated, and the cooling pipeline 200 starts to operate. The cooling pipeline 200 exchanges heat with the high-temperature hydraulic oil in the hydraulic oil delivery pipeline 100 at the heat exchange device 102 to cool the high-temperature hydraulic oil. The low-temperature hydraulic oil cooled by the heat exchange device 102 is returned to the second hydraulic oil chamber of the oil storage tank 902 through the hydraulic oil delivery pipeline 100 and continues to supply the heating device 901 of the equipment.
设备热源900运行初期，也可以液压油旁通阀301关闭，换热装置102关闭，热管式加热器启动从而提高提高液压油输送管路内液压油的温度，直至储油箱温度传感器908或者液压油输送管路温度传感器103检测到液压油的温度达到一定高温（超过60摄氏度），热管式加热器关闭，换热装置102启动。At the initial stage of operation of the equipment heat source 900, the hydraulic oil bypass valve 301 can also be closed, the heat exchange device 102 can be closed, and the heat pipe heater can be activated to increase the temperature of the hydraulic oil in the hydraulic oil delivery pipeline until the oil storage tank temperature sensor 908 or the hydraulic oil The delivery pipeline temperature sensor 103 detects that the temperature of the hydraulic oil reaches a certain high temperature (over 60 degrees Celsius), the heat pipe heater is turned off, and the heat exchange device 102 is started.
其中冷却管路200的工作原理是：Wherein the working principle of the cooling pipeline 200 is:
从压缩机202出来的高温高压气体经过冷凝器203后变为低温高压气液混合体，然后经过储液器204进行气液分离形成低温高压液体，然后经过干燥过滤器205进行除水除杂，然后经过节流装置207形成低温低压液体，低温低压液体在换热装置102内经过换热形成低温低压气液混合体，低温低压气液混合体经过气液分离器201进行气液分离形成低温低压气体，然后低温低压气体再经过压缩机202进行压缩形成高温高压气体，往复上述的循环，从而冷却管路200对经过换热装置102的液压油输送管路100的液压油进行冷却。其中冷却管路200中的冷却管路旁通阀208的作用是在冷却管路200中的压力持续升高达到一定值时，冷却管路旁通阀208打开进行泄压对冷却管路200起到保护作用；冷却管路电磁阀206的作用是在冷却管路200不运作时，放置冷却管路电磁阀206前方的液体向后流至压缩机202内，使得压缩机202损坏，起到保护作用。The high-temperature and high-pressure gas from the compressor 202 passes through the condenser 203 and becomes a low-temperature and high-pressure gas-liquid mixture, and then passes through the liquid receiver 204 for gas-liquid separation to form a low-temperature and high-pressure liquid, and then passes through the dry filter 205 to remove water and impurities. Then, the low-temperature and low-pressure liquid is formed through the throttling device 207. The low-temperature and low-pressure liquid undergoes heat exchange in the heat exchange device 102 to form a low-temperature and low-pressure gas-liquid mixture. The low-temperature and low-pressure gas-liquid mixture passes through the gas-liquid separator 201 to form a low-temperature and low-pressure gas-liquid mixture. Gas, and then the low-temperature and low-pressure gas is compressed by the compressor 202 to form high-temperature and high-pressure gas, and the above-mentioned cycle is repeated, so that the cooling pipeline 200 cools the hydraulic oil passing through the hydraulic oil delivery pipeline 100 of the heat exchange device 102 . Wherein, the function of the cooling pipeline bypass valve 208 in the cooling pipeline 200 is that when the pressure in the cooling pipeline 200 continues to rise to a certain value, the cooling pipeline bypass valve 208 is opened to release the pressure and the cooling pipeline 200 is affected. To protect the role; the role of the cooling pipeline solenoid valve 206 is to place the liquid in front of the cooling pipeline solenoid valve 206 to flow backward into the compressor 202 when the cooling pipeline 200 is not in operation, so that the compressor 202 is damaged and protects effect.
