High and low temperature hot oil circulation pump is a type of circulation pump specifically used for transporting high or low temperature hot oil. Due to its excellent performance under high, low, and corrosive conditions, it has become an important equipment in the thermal industry. This article will introduce its characteristics, scope of application, and maintenance.

1、 Characteristics:

The high and low temperature hot oil circulation pump has the following characteristics:

1. Wide working temperature range: capable of transporting hot oil at high or low temperatures, with a working temperature range of -30 ℃ to 350 ℃;

2. Energy saving and efficient: The use of high-efficiency, leak free mechanical sealing devices and new turbine pump impellers has improved efficiency and energy-saving effects;

3. Stable operation: Adopting a negative pressure self-priming structure, it ensures normal operation under low or high temperature conditions;

4. Low sound and vibration: The well-designed and finely manufactured pump body and motor reduce noise and vibration;

5. Easy maintenance: compact structure, small size, convenient installation and maintenance.

2、 Scope of application:

At present, this pump is widely used in industries such as chemical, oil, plastic, textile, printing and dyeing, medicine, and food. It is mainly used for heating and constant temperature control systems, heat collection, cooling, and transportation of high-temperature liquids in chemical processes. The media used in different industries also vary, such as acid and alkali resistant chemical liquids such as hydrochloric acid, nitric acid, sulfuric acid, hydrofluoric acid, as well as solvents such as toluene and xylene used in petroleum processing.

3、 Maintenance:

The high and low temperature hot oil circulation pump needs to be maintained normally during use, including the following:

Before use, it is necessary to check whether the pump body leaks oil and whether the motor is normal;

2. Regularly clean the pump body, extract residual media from the pump, avoid crystallization of media residue in the pump, and maintain the pump;

3. Regularly replace vulnerable parts such as mechanical seals, bearings, and shaft seals to ensure the stability and efficiency of the pump;

When shutting down, the residual liquid in the pump body should be drained and cleaned to prevent the medium from damaging the pump body.

In short, as an advanced energy-saving equipment, the high and low temperature hot oil circulation pump has the advantages of a wide range of medium temperature, long service life, and easy maintenance, and is one of the indispensable equipment in industrial production. In the future, with technological innovation and expanding demand, the potential of this device in the market will be even greater.
