The role of the vacuum piping system
Manufacturers doubt whether the quality of home-made electromagnetic valve is reliable, but the cost of 200,000 to replace all the electromagnetic valve with imported brand-name electromagnetic valve can not solve the problem of air leakage. In order to completely solve the problem of air leakage, the manufacturer made the following analysis: We can use this feature to make the contact of the vacuum electric contact pressure gauge with the upper electrode and start the water pump, without having to pump until the entire vacuum piping system rises to a very high vacuum. Only turn on the pump. In this way, the purpose of power saving can be achieved, the waiting time for Sheung Shui can be reduced, and work efficiency can be improved.
A check valve is installed behind the solenoid valve to prevent the solenoid valve from leaking and ensure that the pump can pump water for a long time. An electric contact pressure gauge shall be installed on the water outlet pipe of the pump and set on the control circuit. When the water pump is put into normal operation, it is tested whether the water pressure of the water pump is normal. If the water pressure is not normal, immediately control the water valve and stop the operation. At the same time, the sound and light signals of the alarm should be issued to prevent the water pump from idling to protect the pump and save power. Whether the automatic control operation is smooth or not is often affected by the controlled object.
In practice, as an engineering and technical personnel, especially the installation and commissioning of engineering personnel, not only have a strong solid foundation for the professional, but also have a good theoretical foundation and a variety of technical knowledge. In the production practice, full consideration is given to the technical coordination and effective linking between professional and work types, so that a project can be put into operation smoothly.
