An important application of plug-in ultrasonic flow meters is ultrasonic heat meters. Install a heat meter in the heat exchange system. When hot water flows through the system, the temperature compensation of the ultrasonic flow meter and the ultrasonic heat meter involve the measurement of fluid temperature based on the flow rate, supply and return water temperature measured by the heat meter, as well as the time of hot water flow** The measurement of temperature is also very important for improving the accuracy of ultrasonic flow meters. Ultrasonic heat meters have become increasingly popular among heating companies due to their advantages such as high cost-effectiveness, high accuracy, and easy installation and maintenance. Here, the process of using ultrasonic flow meters for heat measurement is briefly explained from the implementation of its flow rate measurement. The flow rate of the medium fluid can be indirectly measured by measuring the time difference between the reverse and forward transmission of ultrasound in the fluid, and the measurement of fluid flow rate is converted into a measurement of time. To improve the measurement accuracy of ultrasonic flow meters, it is necessary to achieve high-precision time measurement. With the rapid development of the semiconductor industry and the maturity of IC technology, time difference ultrasonic flow meters can achieve high-precision measurement. To achieve high accuracy in ultrasonic flow meters, it is necessary to measure the propagation time interval of ultrasonic waves# Plug-in ultrasonic flow meter#
Plug-in ultrasonic flow meter
According to the characteristics of this project, in order to meet the requirements of quality, construction period, and safety in the bidding documents, the configuration of various measuring and testing instruments and construction machinery must meet the following conditions:
1. Various construction instruments and tools must have complete functions, and the degree of novelty must meet the construction needs.
2. The quantity should be sufficient, and different types of instruments and tools should be configured reasonably.
3.During the peak construction period, on the one hand, it is necessary to consider the factor of meeting the quantity, and on the other hand, it is necessary to consider effective turnover and utilization.
4. Ensure the use of construction instruments and tools for important processes and parts. Various measuring instruments not only require advanced functionality, but also require accuracy and effectiveness. Without rules, no square or circle can be formed. Without accurate measurement data for axis and elevation control lines, high-quality engineering cannot be discussed.
5. Configure necessary maintenance tools and perform reasonable maintenance and repair of various instruments and equipment during the construction period.
6. The following factors should be considered when equipping mechanical equipment:
Technical progressiveness: superior technical performance and high productivity of machinery and equipment.
Reliability of use: Mechanical equipment can stably maintain its expected technical performance and operate safely and reliably during use.
Easy maintainability: Mechanical equipment should be easy to inspect, maintain, and repair.
Operational safety: Mechanical equipment has a guarantee performance for construction safety during use.
Economical and Affordable: Machinery and equipment should achieve the lowest cost while meeting technical and production requirements, which can further reduce engineering costs.
Adaptability: A mechanical device that can adapt to different working conditions and work content.
In addition, it should meet the requirements of completeness, energy conservation, environmental protection, flexibility, etc.
Therefore, our company has selected the best and most advanced mechanical equipment for the construction of this project, and will allocate and supplement them at any time according to the needs of the project.
Management system for mechanical equipment installation of plug-in ultrasonic flow meters:
Mechanical equipment and tools need to be managed by professional personnel. According to the construction organization design, prepare the entry and exit plan for mechanical equipment. Any adjustments to lifting equipment and equipment used in special processes during the construction process must be submitted to the original approval department for approval. Responsible for filling out the “Mechanical Equipment Handover Acceptance Form”, “Equipment Maintenance Inspection Form”, “Equipment Maintenance Record Form”, and “Annual Mechanical Equipment Inventory Registration Form”;
Each construction team should carry out regular maintenance of machinery in accordance with the “National Unified Cost Quota for Construction Machinery Teams” and the “Technical and Economic Quota for Maintenance and Repair”, taking into account the actual situation. We should adhere to the “cross operation” method in daily life, which includes cleaning, tightening, adjusting, lubricating, and anti-corrosion. If problems are found, they should be dealt with in a timely manner to keep the mechanical equipment in good condition throughout the construction process.
Mechanical operators, especially those for special types of work, must undergo safety operation technical training and assessment, and hold certificates to work. Non mechanical operators are strictly prohibited from getting on the machine. Machine operators must obey the correct command of construction personnel, strictly implement the “Technical Regulations for Safety in the Use of Construction Machinery”, be responsible for filling out the “Mechanical Equipment Operation Record” form and the “Mechanical Equipment Resume”, and carry out daily maintenance work.
Construction machinery and equipment belonging to special processes must be sent to qualified inspection units for identification before use.
After a major accident occurs, it is necessary to report it to the superior supervisory department in a timely manner by phone or telegram within 24 hours, and then make up the accident report. Dealing with accidents should adhere to the principle of “three not letting go”, that is, not letting go if the cause of the accident is not analyzed clearly; Not letting go of cadres and the masses who have not received education; Do not let go without practical and feasible preventive measures.
Anyone who operates various mechanical equipment without a certificate, once verified, will be fined 100 yuan. If the leader is responsible for using the unlicensed operator to operate the mechanical equipment without a certificate, the leader will be fined 100 yuan. And circulate a notice of criticism.
To purchase mechanical equipment, it is necessary to combine it with the actual production situation and conduct feasibility studies from technical and economic aspects. Only after approval according to the procedures can it be processed.
The backlog of mechanical equipment and equipment that cannot meet the requirements of use and safety due to severe wear and tear or have no value for renovation and need to be scrapped must be approved by the leadership before the scrapping procedures can be processed.
