Troubleshooting Guide for Dalian Chemical Pump

Dalian chemical pumps play an important role in various industries, and their performance and usage directly affect production efficiency and product quality. Therefore, when purchasing, using, and maintaining chemical pumps, it is necessary to choose the appropriate model and specifications according to actual needs to ensure their normal operation. And attention should be paid to safe operation, regular inspections and maintenance should be carried out to ensure the reliability and stability of the equipment, thereby providing guarantees for production.

The types of chemical pumps are very diverse and can be classified according to their structure and working principle. Common chemical pumps include centrifugal pumps, positive displacement pumps, submersible pumps, and magnetic pumps. Centrifugal pump is a common chemical pump, which works by generating centrifugal force through a rotating impeller, sucking liquid into the pump and delivering it under pressure. A positive displacement pump is a type of pump that sucks in and discharges liquids by changing the volume of the chamber, and is suitable for transporting high viscosity liquids. Submersible pumps are suitable for handling deep water and corrosive liquids. Magnetic pumps use magnetic force to drive impellers for liquid transportation, avoiding the use of mechanical seals, making them suitable for handling corrosive liquids.

Troubleshooting Guide for Dalian Chemical Pump

The pump cannot start: it may be a power failure. Check if the power cord has poor contact or if the motor has a short circuit; It is also possible that the motor is damaged and needs to be replaced; In addition, it is necessary to check whether the direction of operation of the host is correct.

After starting the pump, there is no liquid flowing out: first check if there is enough feed liquid at the pump inlet, and then check if the pump is blocked, which may cause the pump to fail to operate.

Pump outlet pressure too high: It may be due to the pump speed being too fast, causing the outlet pressure to be too high. At this point, the outlet pressure can be reduced by adjusting the pump speed or replacing the appropriate impeller.

Excessive pump vibration: It may be due to damaged parts of the pump itself, causing imbalance, and requiring repair or replacement of parts.

Excessive pump noise: It may be due to damaged bearings or poor lubrication, and bearings need to be replaced or lubrication needs to be strengthened.

Pump leakage: The reason for pump leakage may be due to aging or wear of the seals, which need to be replaced. In addition, it is necessary to check whether there are cracks or poor welding in the pump body.

Excessive pump temperature rise: It may be due to the large gap between the pump rotor and the pump casing, which leads to an increase in leakage and subsequently causes excessive temperature rise. Need to readjust the clearance of the pump.

The selection of chemical pumps should be determined based on specific process requirements and medium properties. When selecting, it is necessary to consider factors such as the properties of the medium, flow rate, head, pressure, temperature, concentration, etc., and combine them with working conditions and requirements for comprehensive consideration. In addition, it is necessary to choose the material and sealing form of the pump reasonably to adapt to the requirements of different media transportation and different working environments. For example, pumps made of corrosion-resistant materials can be used when transporting corrosive media; When transporting high-temperature media, high-temperature resistant materials can be selected and insulation measures can be taken.

The application fields of chemical pumps are very extensive. They are widely used in industries such as petrochemicals, pharmaceuticals, food and beverage, and metal smelting. In the petrochemical industry, chemical pumps are used to transport crude oil, petroleum products, and chemicals. In the pharmaceutical industry, chemical pumps are used to transport drugs and chemical reagents. In the food and beverage industry, chemical pumps are used to transport food and beverage raw materials. In the metal smelting industry, chemical pumps are used to transport molten metal and coolant. The application of chemical pumps in these industries is crucial as they ensure the safe and efficient transportation of liquids.
