Precautions for Using Chemical Centrifugal Pumps

Time：2026-01-27 15:29:54 Edit：HuaQuan Traffic Index：90

A chemical centrifugal pump is a fluid transport device that uses the rotation of an impeller to impart centrifugal force to a liquid, thereby increasing its mechanical energy for transportation. It is one of the most commonly used liquid fluid conveying equipment in chemical plants.

I. Characteristics of Chemical Centrifugal Pumps
Chemical centrifugal pumps have the characteristics of corrosion resistance, high temperature resistance, and high pressure resistance. They use a reliable sealing structure (such as mechanical seals) and can safely transport toxic, flammable, explosive, or highly corrosive chemical media. They are core fluid transport equipment in chemical production.

II. Huaquan Power is a professional chemical centrifugal pump manufacturer in China.
Huaquan Power Company was established in 2010. Its industries involve power generation equipment, new energy storage equipment, high and low voltage complete sets of equipment, power engineering, and multiple other fields. The company has created three major brands: "HQ-POWER," "HUAQUAN," and "Huaquan." Currently, the company has developed into a strong global brand in the power industry, with cumulative global sales exceeding 1 million units.

III. Advantages of Chemical Centrifugal Pumps
1. Simple and reliable structure of Chemical Centrifugal Pump: Compact design, smooth operation, and easy maintenance.
2. Large and uniform flow: Suitable for continuous and stable high-flow transportation, easy to adjust.
3. Strong corrosion resistance: Chemical centrifugal pumps can transport various corrosive media by using special materials.
4. Wide range of applications: Can meet various conventional transportation needs in chemical production with high cost-effectiveness.

IV. Precautions for Using Chemical Centrifugal Pumps
1. Strictly Prohibit Dry Running: Before starting the chemical centrifugal pump, it must be fully filled with liquid. During operation, ensure there is no gas at the inlet.
2. Correct Start and Stop: Close the outlet valve when starting to start under light load. Before stopping, first partially close the outlet valve.
3. Prevent Cavitation: Ensure adequate inlet pressure and avoid blockage in the inlet pipe or too small a valve opening.
4. Monitor Operation: Closely monitor the Chemical Centrifugal Pump pressure, flow, vibration, noise, and bearing temperature, and address any abnormalities immediately.
5. Regular Maintenance: Check and maintain mechanical seals and bearing lubrication, and regularly clean the filter.

V. Q&A on Chemical Centrifugal Pumps
1. Which key parameters need to be monitored during the operation of a chemical centrifugal pump?
The pump's outlet pressure, flow rate, motor current, and bearing temperature should be closely monitored to ensure they remain within normal ranges.
2. How is the flow rate of a chemical centrifugal pump adjusted?
The most common method is to adjust the opening of the valve on the outlet pipeline. A more energy-efficient way is to change the pump's speed (e.g., using a variable frequency drive).
3. What is the core working principle of a chemical centrifugal pump?
The driver rotates the impeller, and the blades in the impeller drive the fluid to rotate as well, generating centrifugal force. The fluid is thrown toward the impeller outlet and delivered into the discharge pipe through a diffuser or volute casing.

VI. Application Areas of Chemical Centrifugal Pumps
1. Petrochemical Industry: Chemical centrifugal pumps are used to transport petroleum products such as crude oil, gasoline, and diesel, as well as media like acids, alkalis, and catalysts.
2. Chemical Pharmaceuticals: Widely used for conveying chemical drugs, pharmaceutical raw materials, and organic solvents, meeting the needs for continuous transport and metering.
3. Metallurgy and Power: Used in the metallurgy industry and thermal power plants to transport various process liquids and cooling water.
4. Environmental Technology: Chemical centrifugal pumps are used in the treatment of wastewater and waste gas to convey sewage and waste liquids, enabling the collection and treatment of pollutants.
5. Food Processing: Used to transport various liquids, semi-liquid foods, and food additives, requiring good hygiene and safety characteristics.
6. Municipal and Construction: Chemical centrifugal pumps are applied in water supply, heating, air conditioning cooling circulation systems, fire protection, and irrigation.

Chemical centrifugal pumps are suitable for transporting highly corrosive media and also play an important role in fields such as new energy chemical engineering. Users should select the appropriate chemical centrifugal pump based on specific operational needs.
