Hot oil pump is a key equipment for conveying high temperature liquid, which is widely used in petroleum, chemical, electric power and other fields. Its working principle and structural characteristics make it stable and efficient in high temperature and high pressure environment.

The working principle of 1. hot oil pump

The working principle of the hot oil pump is based on the general principle of centrifugal pumps. It generates centrifugal force through the rotation of the impeller, and pushes the liquid from the inlet to the outlet at a certain speed and pressure. In the hot oil pump, because the high temperature liquid is handled, it is also necessary to consider the thermal expansion, thermal stress and other factors on the performance of the pump. In addition, in order to maintain the normal operation of the pump, it is also necessary to cool the bearings of the pump to prevent damage due to high temperature.

The working principle of the hot oil pump is based on centrifugal force and lubrication properties. When the motor is started, the pump rotor is rotated by the driving device to form centrifugal force. The centrifugal force causes the hot oil to be thrown to the outer periphery of the pump body and then into the flow passage of the pump body. At the same time, the volume inside the pump body decreases, forming a certain vacuum, so that the hot oil is sucked into the pump body. Then, as the pump rotor rotates, the hot oil is pushed to the outlet of the pump by centrifugal force and transported to the equipment or system that needs to be heated. In this way, the circulating transportation of the hot oil is realized.

Structure of 2. hot oil pump

The structural design of the hot oil pump is reasonable to ensure efficient and stable work. The pump body is usually made of cast iron or stainless steel, which has good strength and corrosion resistance. The motor is connected to the pump rotor through a shaft, which can provide sufficient driving force. In addition, the hot oil pump is also equipped with a sealing device to prevent the leakage of hot oil in the pump body or the entry of external impurities. Common sealing devices include two types of mechanical seals and packing seals, which are designed and selected according to specific working conditions and requirements. The structural design of the hot oil pump is to meet its working requirements as the core. Its main structure includes pump body, impeller, bearing, seal ring and so on.

1. Pump body: The pump body is the main part of the hot oil pump, usually made of cast steel or stainless steel to withstand the pressure and corrosion of high temperature liquids.

2. Impeller: Impeller is a key component of centrifugal force, its shape and material according to the nature of the transport liquid and temperature to choose.

3. Bearing: The bearing is a key component that supports the rotation of the impeller. It is usually made of high temperature resistant materials to ensure stable operation in high temperature environments.

4. Seal ring: In order to prevent liquid leakage, the hot oil pump adopts a special sealing structure. The sealing ring is one of the key components, which can effectively prevent the liquid from leaking from the pump shaft.

In addition, the hot oil pump is also equipped with auxiliary equipment such as temperature control system and pressure sensor to realize real-time monitoring and adjustment of the working state of the pump. These devices enable the hot oil pump to work stably and efficiently in high temperature and high pressure environments.

Hot oil pump is an important industrial equipment. Through its working principle and structural design, it realizes efficient and stable hot oil transportation. It is widely used in many fields, such as chemical, plastic, textile, food processing and other industries. The operation of hot oil pump can improve energy efficiency and reduce energy waste, so it has been widely concerned and applied.

In short, the working principle of the hot oil pump is based on the principle of a centrifugal pump, and its structural design is centered on meeting the working requirements of high temperature and high pressure environments. Through reasonable structural design and material selection, hot oil pump can play an important role in petroleum, chemical, electric power and other fields, providing stable and efficient liquid transportation services for industrial production.
