With the continuous updating and progress of science and technology, many traditional equipment and products have been gradually moving toward modernization. All kinds of equipment have become more and more intelligent and convenient, and the use effect and service life Continuous improving. Our pump has developed for a long time to become more suitable for our production needs. At the same time more information needs our understanding, such as water pump turbine speed test measures what? Pumping Turbine Overspeed Test Measures Feedwater Pump Turbine Overspeed Test Measures mainly include the following steps: First, the prerequisites should have the requirements and requirements 1, inspection of small machine overhaul has been completed, on-site equipment intact and available. 2. Confirm that the back wheel of small machine and feed pump has been unlocked, the static test of the small machine speed regulation system is qualified, and the local and MEH emergency stop button is in the normal operation. 3, check to confirm the small shaft seal system, the vacuum is normal. 4, the main pump, accident pump interlock protection test qualified, host EH oil system, the vacuum system is operating normally. Second, the test process 1, first hand drive disk drive device, check the flexible into the electric disk drive, carefully listen to whether there is a metal friction, keep the disk drive running for more than 2 hours. 2, Turn on the auxiliary steam to the small machine and debug the isolation valve with auxiliary steam, and connect it to the manual steam valve of small machine, and the auxiliary steam pipe to the front of the low pressure main steam valve. 3, Click "LATCH MEH" on the MEH operation screen to lock up the small machine, check the high pressure of the low pressure main valve, and keep the pressure in front of the door keep 0.15MPa and the steam temperature reaches above 300 ℃. Through the above analysis, we have preliminary understanding of the water pump turbine speeding test measures, but these are only a small part of the actual production process and use of a lot of content. This requires more discoveries and conclusions from users and experts and scholars.
Overhead Sectional Door
Overhead sectional door most widely used for loading areas on all types of industrial premises and Designed with a curved overhead track, these vertically-opening sectional doors can be installed in areas with reduced head room. They provide heat and sound insulation with its composite panel construction.
The counterbalance and cable system provides quiet and straight forward operation for manual doors. Electric operation is available for larger applications that can incorporate many alternative operator options to suit all client requirements.
The standard outer panels are manufactured from 0.5mm thick, high quality zinc coating to BS EN 10147
For the best weather protection the sectional door panel has an interlocking hinged joint integrating a high quality seal the full length of the panel.
A counterbalance system is incorporated into the sectional overhead door to ensure efficient and effortless operation.
The counterbalance comprises of springs mounted on a steel shaft that are high tensile helical wound steel. It has been heat treated for enhanced performance for around 50,000 cycles.
Reducing shaft friction is achieved with the aid of brackets and guide rollers incorporating highest quality sealed bearings.
