The RY-type air-cooled high-temperature heat-conducting oil pump, often referred to as a heat-conducting oil pump, high-temperature heat-conducting oil pump, or heat-conducting oil circulating pump, is highly versatile due to its robust structure and excellent performance. This pump is extensively utilized across various industries, thanks to its ability to handle extreme temperatures and maintain superior sealing capabilities. This represents a major advancement in oil pump technology.
Heat pumps can be classified into single-acting and double-acting types. A single-acting heat transfer oil pump performs suction and discharge operations during one reciprocating cycle of its piston. In contrast, a double-acting heat transfer oil pump completes two suction actions per cycle. Depending on the number of cylinders, these pumps come in single-cylinder, double-cylinder, and triple-cylinder models.
Regarding sealing options, the RY heat transfer oil pump offers several choices:
1. **Metal Bellows Mechanical Seal**: Known for its compact design and ease of installation, this seal typically lasts 2 to 3 times longer than conventional seals when using the same auxiliary systems.
2. **Double-Ended Mechanical Seal**: Utilizing a circulation system with external cooling, this seal's lifespan is 1.5 to 2 times that of a single-ended seal.
3. **Single-Ended Seal**: Employing injection flushing with a flushing fluid at approximately 100°C (usually paraffin oil), the pressure exceeds the sealed cavity by 0.05 to 0.15MPa. External cooling with hot water (soft water) further enhances cooling efficiency, allowing the pump to operate effectively for cycles lasting up to ten months.
4. **Hard and Soft Friction Pairs**: Options like YG6/YG8 or SiC/SiC are ideal for handling media with high viscosity, small solid particles, or crystallization, ensuring optimal performance.
To analyze the cooling mechanisms for hot oil pumps, consider the following:
- Around the sealed chamber, a cooling water jacket is installed, allowing cold water to circulate and reduce the chamber temperature to between 200°C and 250°C.
- For single-end seals, injection flushing with wax oil (around 100°C) is employed. This not only cools the pump but also improves the working environment, making it an efficient solution.
- External quench water is used to further cool and prevent blockages in the system.
In summary, the RY-type heat-conducting oil pump combines advanced sealing technologies and cooling methods to ensure reliable operation under demanding conditions, making it a standout choice in the oil pump industry.
