Anonymous users2024-02-11Based on what you said, I think you should be using a liquid ring vacuum pump (water ring vacuum pump).
The functions of its individual parts are as follows:
1. Pipeline pump (optional): mainly used for the working fluid of the water ring vacuum pump, its flow rate can be selected according to the working fluid flow requirements of the vacuum pump, such as the working fluid is recycled and the pipeline resistance is small, the pipeline pump can be used without the water ring vacuum pump.
2. Thermometer (optional): installed in the working fluid pipeline to measure the inlet water temperature of the vacuum pump, if the inlet water temperature of the water ring vacuum pump is too high, it will affect the ultimate vacuum and pumping rate of the water ring vacuum pump.
3. Liquid resistance device (necessary parts): The function of the liquid resistance device is equivalent to a one-way valve, but it is a one-way valve without resistance, and its main function is to close the pipeline between the vacuum pump and the system when the water ring vacuum pump is shut down unexpectedly.
If there is no such liquid blocker (also known as vacuum check valve, vacuum check valve, etc.), please refer to it.
When the water ring vacuum pump is stopped unexpectedly or normally, because the system is in a vacuum state, and the water ring vacuum pump changes to atmospheric pressure in an instant, the water in the water ring vacuum pump will be pumped into the system.
4. Gate valve (necessary parts): mainly used to control and close the suction port pipeline and working liquid pipeline of the water ring vacuum pump.

Anonymous users2024-02-08Vacuum system. It is a complete set of vacuum system composed of vacuum pump, PLC program control system, air storage tank, vacuum pipeline, vacuum valve, overseas filtration assembly, etc. At present, the system is widely used in the electronic semiconductor industry, photoelectric backlight module, machining and other industries.
Do you mean that the pressure decrease is that the gauge hand is shifting in the direction of 0, it should be said that the pressure is rising, right? The reason may be that when the gas in the container is pumped out to negative pressure, the temperature of the container will decrease, and the surface of the container will absorb heat during the period of maintaining pressure, and the gas in the container will expand, and the watch hand will shift to the 0 direction.
1. Dynamic positioning system (dynamic positioning system) is a closed-loop control system, which uses thrusters to provide environmental forces that resist wind, waves, currents and other acts on the ship, so that the ship can be kept in the required position on the sea level as much as possible, and its positioning cost will not increase with the increase of water depth, and the operation is also more convenient. >>>More

Through the operation of the workshop management system, the quantity of work-in-progress has been effectively controlled and reduced, the work efficiency of the workshop has been improved, and some workshop positions have changed the working mechanism and simplified the operation procedures. The documents have been reduced to about 30% of the original, and the relevant management departments have also cooperated with the introduction of the relevant workshop management system. Therefore, more adjustments and changes of relevant systems are reflected in workshop management. >>>More
