Two high - quality titanium materials, TA2 and TA10, are available. They exhibit super - strong resistance to various highly corrosive media. Whether in strong acid, strong alkali environments or working conditions with corrosive particles, the equipment can be effectively protected from corrosion, greatly extending the service life of the equipment and reducing the equipment replacement and maintenance costs of enterprises.
It can easily adapt to a variety of complex working conditions and operate stably under extreme conditions such as high temperature, high pressure, and high humidity. Whether in the reaction processes of the chemical industry, the fine processes of the pharmaceutical industry, or the waste - gas treatment in the environmental protection field, it can exert its excellent performance and meet the diverse needs of different industries.
It adopts an advanced complete skid - mounted structure, integrating the screw pump and its supporting equipment on one skid. During installation, only the skid needs to be positioned as a whole, and after connecting the pipelines and lines, it can be put into use, which greatly shortens the installation period and reduces the on - site installation workload. At the same time, front/back - end condensation and recovery devices can be flexibly configured according to actual needs, achieving efficient resource recovery and utilization, reducing production costs, and conforming to the concept of green and environmental - friendly production.
It has an independently developed patented internal cooling structure. By ingeniously designing cooling channels inside the pump body, the cooling medium circulates in the channels, which can quickly and effectively take away the heat generated during the operation of the pump body. This ensures that the pump body always maintains a stable operating temperature during long - term continuous operation, avoids equipment failures and performance degradation caused by excessive temperature, and significantly improves the reliability and working efficiency of the equipment.
A large - scale chemical enterprise faced extremely harsh production conditions when producing a new chemical product. During the production process, a large amount of waste gas containing highly corrosive gases was generated, and the requirements for the corrosion - resistance of the gas - extraction equipment were extremely high. The ordinary screw pumps used in the past frequently malfunctioned due to severe corrosion shortly after being put into use, which not only affected the production progress but also led to high equipment maintenance and replacement costs.
After adopting the titanium - series screw pump (model LGB70D), the situation was fundamentally improved. The selected TA2 titanium material successfully withstood the erosion of highly corrosive gases. The equipment operated stably in the harsh working environment, and the pumping rate always remained at 70L/S (250m³/h), meeting the production demand for the rapid extraction of waste gas.
The complete skid - mounted design enabled the installation and commissioning of the equipment to be completed in a short time and put into production quickly. At the same time, the back - end condensation and recovery device configured according to the production process requirements effectively recovered the useful components in the waste gas, not only reducing production costs but also reducing environmental pollution.
The patented internal cooling structure ensured the stability of the pump body during long - term high - load operation. The motor power always remained at 7.5KW, and there was no power fluctuation or equipment failure caused by excessive temperature. The production efficiency of the chemical enterprise was greatly improved, and the equipment failure rate was significantly reduced, bringing significant economic and environmental benefits to the enterprise.

First, check whether the inlet pipeline is blocked and clean the impurities and foreign objects in the pipeline; check whether the seals are damaged and replace them in a timely manner if there is damage to prevent gas leakage from affecting the pumping; check the wear of the screws. Severe wear will reduce the pumping efficiency, and the screws need to be repaired or replaced; in addition, confirm whether the motor speed is normal. A decrease in the motor speed caused by a motor failure will also reduce the pumping rate.
Regularly check the quality and oil level of the lubricating oil and replace the lubricating oil at the specified time; check the sealing performance of the seals and replace the worn seals in a timely manner; clean the filter to prevent impurities from entering the pump body; check the wear and corrosion of the screws and repair or replace them if necessary; clean the appearance of the equipment to keep the equipment clean.
Select the appropriate titanium material (TA2/TA10) and reasonably select according to the strength of the medium's corrosiveness; avoid the over - temperature and over - pressure operation of the equipment, because extreme working conditions will accelerate corrosion; regularly inspect the equipment to check for signs of corrosion. If local corrosion is found, deal with it in a timely manner; use corrosion - resistant pipelines and connecting parts to ensure the consistent corrosion - resistance performance of the entire system.
Ensure that the installation foundation is flat and firm and can withstand the weight and vibration during the operation of the equipment; accurately position the skid - mounted equipment according to the installation drawings and adjust the levelness; pay attention to sealing when connecting the pipelines to prevent leakage; the electrical connection should be standardized and the grounding protection should be well done; after the installation is completed, check each component to ensure that the connections are firm and there are no loose phenomena.
