Pressure gauge refers to the instrument that uses elastic components as sensitive components to measure and indicate higher than ambient pressure. It is widely used in hydraulic systems, thermal pipe networks, oil and gas transmission, water supply and gas supply systems, and vehicle maintenance and repair shops. Due to the high mechanical strength and ease of production of the elastic sensitive components of mechanical pressure gauges, mechanical pressure gauges are becoming more and more widely used. The working principle of the pressure gauge is to deform the elastic deformation of the sensitive components in the watch, and then the deformation mechanism of the movement inside the watch transmits the pressure deformation to the pointer, causing the pointer to rotate to display the pressure. How to maintain the pressure gauge in daily use? When the pressure gauge is found to be out of alignment during operation, it must be replaced in time. The specific operation is as follows: 1. The replaced pressure gauge must be a sealed seal that has passed the calibration of the metrological department, a pressure gauge that is valid for verification, or a new one with a certificate of factory qualification. 2. Before changing the meter, the three-way cock should be screwed to the position of the flushing pressure gauge to clean the dirt in the trap. 3. Turn the three-way cock to the position where the trap is stored. Use a wrench to remove the old watch and replace it with a new one. 4. Turn the three-way cock to the normal working position to put the new watch into operation. The pressure gauge is operated for three months for a first-level maintenance. The specific operations are as follows: 1. Check the three-way cock and trap pipe joint to eliminate leakage. 2. Check if the pressure gauge can return to zero. 3. Check and flush the trap to ensure smooth flow. After one year of operation, the pressure gauge is subjected to secondary maintenance. The specific operations are as follows: 1. Disassemble the pressure gauge and send it to the metrology department for verification and sealing. 2. Disassemble and check the trap and the thread should be intact. 3. Disassemble and inspect the three-way cock, grind the sealing surface to ensure strict leakage, and the connecting thread should be intact. 4, water trap, three-way cock rust, paint and paint. ----- Responsible Editor: Dalan Oil Pump Motor 02- Purchasing Consultant Copyright http:/(Dalan Motor) Reprint, please indicate the source http://news.chinawj.com.cn Indoor Lighting is an important part of indoor environment design, and indoor lighting design is conducive to people's activities and safe life.
