1. Conditions of use

The double cooler is designed and manufactured in accordance with the GB151 standard and with reference to the West German AD and American TEMA standards. It adopts an all-steel and partial brass structure. The working pressure on the oil side is 1.6MPa, the working temperature is 150℃, and the working pressure on the water side is 1.0MPa. Temperature 100℃. The product has the advantages of energy saving, high efficiency, safety and reliability; it is suitable for oil cooling systems in turbine generator units, compressor units, fans, pump units and petrochemical industries, and can also be used in other oil cooling systems.

2. Characteristics

1. The data listed in the table are for two-process tube-type double oil coolers. If necessary, four-process, six-process, bare tube or fin cooling tube coolers can be selected.

2. The cooler is usually installed horizontally. If the user needs it, two vertical arrangements can be used, one with the water inlet chamber at the bottom and the other with the water inlet chamber at the top to facilitate the disassembly of the pipe bundle.

3. The oil-water interface flange standard is according to JB/T81-94. When matching non-standard flanges according to user requirements, the piping requirements should be met.

4. According to the API 614 standard, the cooler adopts a double structure, consisting of two coolers of the same area and a three-way valve device. One is working and the other is standby. Each cooler can withstand the cooling load of the entire system. One end of the plate is fixed and the other end is floating. The removable pipe bundle and water chamber cover facilitate cleaning, inspection and maintenance during operation. The material of the cooler can be selected in many ways according to the place of use and water system conditions.Process lubrication, the water chamber, shell, and three-way valve can be selected from carbon steel or all stainless steel, and the tube plate can be made from carbon steel, stainless steel, or brass plate; the tube material can be ordinary brass tube H68, arsenic brass tube HSn70-1A, aluminum yellow Copper tube HA177-2A, stainless steel tube 1Cr18Ni9Ti, B10, B30, etc.

5. The three-way valve adopts a steel welded structure continuous flow switching valve. This kind of valve will not cause interruption of the oil circuit when the internal structure fails or during valve switching. The appearance is as shown in the figure.
