Case Description

A large petrochemical company specializing in the production of road asphalt, products are widely used in various types of highway construction projects. Asphalt production process requires different components of petroleum raw materials at high temperature mixing, reaction, raw material transportation and mixing uniformity requirements are extremely high. Before the introduction of Rotary Lobe Pump, enterprises use ordinary centrifugal pumps to transport raw materials, as asphalt raw materials at high temperatures still have a high viscosity, centrifugal pumps with low transport efficiency, and easy to flow fluctuations, resulting in batches of asphalt product quality is not stable. At the same time, the impeller of the centrifugal pump in the high-viscosity, impurity-containing raw materials under the scrub, wear and tear, frequent maintenance, greatly affecting the production schedule.

Solution

The company introduced 6 high temperature and high viscosity Rotary Lobe Pump from Bonve. These Rotary Lobe Pump are designed for the characteristics of asphalt production, with special materials that can withstand high temperatures, and a unique structure that can efficiently transport high-viscosity raw materials to ensure a stable and accurate flow rate. In production, the Rotary Lobe Pump transport different raw materials to the reaction kettle in precise proportions, and cooperate with the mixing equipment to make the raw materials fully mixed and reacted.

The equipment supplier provides detailed installation guidance, operation training and regular maintenance program for the enterprise. After the introduction of Rotary Lobe Pump, the quality of asphalt products has been greatly improved, and the quality difference between batches has been reduced, which fully meets the needs of high-standard road construction. The equipment failure rate is significantly reduced, the number of repairs is reduced, the production efficiency is greatly improved, saving a lot of costs for the enterprise and enhancing market competitiveness.
