In a complete set of units, it also includes all auxiliary equipment required for the closed - loop system, such as condensers, filters, and circulating water pumps.
Check whether all components of the equipment are firmly connected, whether the lubricating oil, coolant, etc. are sufficient, and whether the electrical system is normal. Inject an appropriate amount of working fluid, generally water or other suitable liquids, into the pump.
First, start the motor to drive the pump shaft to rotate, causing the working fluid to form a rotating liquid ring inside the pump. As the liquid ring rotates, the volume of the pump cavity changes periodically, thus achieving the processes of suction, compression, and exhaust.
During the operation of the equipment, real - time monitor parameters such as the vacuum degree, pressure, and flow rate of the pump through instruments such as vacuum gauges and pressure gauges installed on the pipeline. At the same time, check the operating sound and vibration of the equipment to ensure its normal operation.
Adjust the operating parameters of the pump according to different process requirements. For example, in the vacuum drying process, adjust the vacuum degree and temperature according to the characteristics of the material and the drying requirements; in the distillation process, control the vacuum degree and heating temperature to achieve the separation and purification of the material.
First, stop the motor, then close the inlet and outlet valves, and drain the working fluid in the pump. Clean and maintain the equipment, check the wear of seals, bearings, and other components, and replace vulnerable parts in a timely manner.

Selecting the appropriate model requires considering multiple factors, such as the vacuum degree required by the process, the pumping rate, the nature of the working medium, and the temperature and pressure of the working environment. If the process requires a high vacuum degree, a model that can achieve a higher vacuum degree can be selected; if the pumping rate requirement is high, a pump model with the corresponding pumping rate should be chosen. At the same time, the appropriate material should be selected according to the corrosiveness and other characteristics of the working medium.
First, check whether the working fluid of the pump is sufficient. Insufficient working fluid may lead to a decrease in sealing performance and affect the vacuum degree, and the working fluid should be replenished in a timely manner. Secondly, check whether there is leakage in the pipeline, which can be detected by methods such as applying soapy water. If there is leakage, it needs to be repaired in a timely manner. In addition, check whether components such as the impeller and seals of the pump are worn. If the wear is severe, the components need to be replaced.
Daily maintenance is recommended to be carried out every day, including checking the operating status of the equipment, the liquid level and quality of the working fluid, and the vibration and noise of the equipment. Regular maintenance can be carried out every 1 - 3 months, including changing the lubricating oil, cleaning the filter, and checking the seals. Comprehensive maintenance can be carried out every six months or a year, comprehensively testing and repairing the equipment and replacing vulnerable parts.
The pump body is made of materials that meet food hygiene standards, such as stainless steel, to avoid contamination of food. The working fluid also needs to be a food - grade liquid, and the quality of the working fluid should be regularly replaced and tested. At the same time, in the design and installation of the equipment, ensure that there are no dead corners, which is convenient for cleaning and disinfection to prevent the growth of bacteria.
Select appropriate materials according to the corrosiveness of the medium, such as stainless steel, duplex steel, titanium, or special materials Ni - Resist D2B, Hastelloy B, CUranus B6, etc. Special treatment should be carried out on key components such as the seals and impeller of the pump to improve their corrosion resistance. During use, regularly inspect and maintain the equipment to discover and handle corrosion problems in a timely manner.
The TXV series itself has energy - saving advantages, saving 15% - 20% energy compared to traditional products. During use, reasonably adjust the operating parameters of the pump to make it operate under the best working conditions and avoid unnecessary energy consumption. For example, adjust the pump speed according to the process requirements or use variable - frequency control to reduce the power consumption of the motor while meeting the pumping requirements.
During installation, ensure that the foundation is firm and can withstand the weight and vibration of the pump during operation. The connection of the inlet and outlet pipelines of the pump should be correct to avoid pressure buildup or leakage. At the same time, ensure that the supply and discharge systems of the working fluid are normal to ensure the smooth circulation of the working fluid. The installation of the electrical system should comply with relevant standards to ensure the safe operation of the equipment.
In addition to ensuring that the pump body materials and working fluid meet the requirements of pharmaceutical production, the equipment also needs to be regularly cleaned and disinfected to ensure that there are no residual impurities and microorganisms inside the equipment. During the operation of the equipment, strictly control parameters such as the vacuum degree and temperature to ensure the stability and consistency of the pharmaceutical production process. At the same time, establish a complete equipment maintenance and management record for easy traceability and supervision.
The pumping rate is mainly affected by factors such as the pump speed, the temperature and flow rate of the working fluid, the nature and pressure of the gas, and the pipeline resistance. A decrease in pump speed will lead to a decrease in the pumping rate; too high a temperature or insufficient flow rate of the working fluid will affect the sealing performance and pumping efficiency of the pump; a high viscosity, high pressure of the gas, or large pipeline resistance will all hinder the flow of gas and reduce the pumping rate.
Although the price of the TXV series vacuum pump may be relatively high, its excellent performance can bring long - term benefits to enterprises. Its advantages such as high - efficiency, energy - saving, convenient maintenance, and strong adaptability can reduce the operating costs of enterprises, improve production efficiency and product quality. In the long run, its cost - performance ratio is much higher than that of ordinary vacuum pumps, making it an ideal choice for enterprises to enhance their competitiveness.
