How to judge the performance of Dalian Chemical Pump?

In chemical production, Dalian chemical pumps are indispensable and important equipment. It can not only improve production efficiency and achieve fast and stable liquid transportation, but also ensure safety and reliability during the production process. Therefore, when choosing chemical pumps, we should carefully consider selecting suitable equipment and regularly maintaining them to extend the service life of the pump and ensure the smooth progress of the production process.

Chemical pumps should be installed on a sturdy and flat foundation, with a size and strength that can withstand the weight of the pump and the vibrations generated during operation. Generally, the foundation should be inspected and accepted before installation to ensure that the flatness error of the foundation is within the allowable range. For example, for large chemical pumps, the foundation is poured with concrete and anchor bolt holes are reserved for fixing the pump body. During installation, the pump body should be accurately placed on the foundation and the levelness of the pump body should be adjusted with a spirit level to ensure that the pump shaft is in a horizontal state, in order to reduce vibration and wear during pump operation.

How to judge the performance of Dalian Chemical Pump?

The flow rate of chemical pumps is an important performance indicator. Flow rate refers to the volume of liquid delivered by a pump per unit time, usually expressed in cubic meters per hour (m ³/h) or liters per minute (L/min). The larger the flow rate, the stronger the pump's drainage capacity, and the corresponding increase in production efficiency. Therefore, the performance of the pump can be judged by testing its flow rate.

Secondly, the head of the chemical pump is another important performance indicator. Head refers to the maximum height at which a pump can transport liquid, and can also be understood as the conveying capacity of the pump. Usually expressed in meters (m), the higher the head, the stronger the pump's conveying capacity, and it can deliver to higher places. Therefore, the performance of the pump can be evaluated by testing its head.

In addition, the efficiency of chemical pumps is also an important indicator. The efficiency of a pump refers to the ratio at which mechanical work is converted into fluid work when the pump rotates, usually expressed as a percentage. The higher the efficiency of the pump, the higher the energy utilization rate of the pump, the smaller the loss, and the ability to save energy and costs. Therefore, the pump with better performance can be selected by comparing the efficiency of different pumps.

Furthermore, the operational stability of chemical pumps is also an important indicator for evaluating performance. The operational stability of a pump refers to whether it can maintain stable performance over a long period of operation, and is less prone to failure and damage. The operational stability of the pump can be evaluated by examining its design structure, materials, and manufacturing process.

In addition, the corrosion resistance and wear resistance of chemical pumps are also important performance indicators. Corrosive liquids and particles are often involved in the chemical industry, so the corrosion resistance and wear resistance of pump materials and coatings are very important. The corrosion resistance and wear resistance of the pump can be evaluated by examining its material and coating performance parameters.

Chemical pumps can be mainly divided into impeller type, plunger type, screw type and other types in terms of working principle. Different types of chemical pumps are suitable for different working conditions and environmental requirements. For example, in the process of chemical production, it is often necessary to transport corrosive liquids with high concentration and high temperature, which puts higher demands on the sealing, corrosion resistance, and high temperature resistance of chemical pumps.

Chemical pumps need to be inspected regularly, including checking the appearance of the pump body, whether the connection parts are loose, and whether the seal is leaking. For example, for pumps with mechanical seals, it is necessary to check whether there is liquid dripping at the seal. Under normal circumstances, the leakage of mechanical seals should be very small. If a significant increase in leakage is found, it may be due to wear or damage to the sealing surface, and it needs to be repaired or replaced in a timely manner. At the same time, it is necessary to check the bearing temperature and vibration of the pump. Excessive bearing temperature may be caused by poor lubrication or bearing wear, while excessive vibration may be caused by pump shaft imbalance, poor coupling alignment, and other reasons.
