1. Shaft seal flow switch (sealing water flow switch)
Detailed explanation of shaft seal flow switch (sealing water flow switch) Shaft seal flow switch, also known as sealing water flow switch, is an important device used to monitor and regulate the water flow and pressure in the shaft seal device. It is widely used in various equipment with shaft seal devices (including mechanical shaft seals and packing), such as pumps, reactors, sieves, agitators, etc. The working principle of the shaft seal flow switch is based on fluid dynamics and mechanical principles. When the filtered cooling lubricating water enters the system distribution plate from the inlet, it enters the flow measurement unit. Inside the measuring unit, a cylindrical float embedded with a white ring moves under the action of fluid. When the flow rate remains constant, the float is in a stationary state, and the white ring points to a determined flow scale value. This flow rate value is used to monitor the water flow inside the shaft seal device, ensuring that it is within the normal range.
2. Structure Composition: The shaft seal flow switch is mainly composed of the following components: hose joint: used to connect the water pipe and the flow switch.
. Flow regulating valve: used to regulate the water flow entering the shaft seal device. Target traffic indication: Display the preset target traffic value. Scale flow indication: displays the actual flow value. Alarm switch: When the actual flow rate is lower than the preset value, an alarm is triggered. Alarm switch mounting seat: used for installing alarm switches. Flow meter core components: including core components such as float and measuring tube. Cleaning knob: used for cleaning me_600x400.jpg)
III. Function and Characteristics Monitoring and Adjustment: The shaft seal flow switch can monitor the water flow and pressure inside the shaft seal device in real time, and automatically adjust the water flow and pressure as needed to ensure the normal operation of the shaft seal device.
. Alarm function: When the actual flow rate is lower than the preset value, the alarm switch will trigger an alarm to remind the operator to take timely measures. Resource saving: The shaft seal flow switch is a water resource energy-saving product that can reduce the waste of water resources. Easy to maintain: The measuring tube and internal components can be easily cleaned by cleaning the knob, keeping them clean and accurate. Shouting rent4. Application examples: Shaft seal flow switches are widely used in various industrial fields, such as chemical, petroleum, pharmaceutical, etc. In these fields, the shaft seal device is an important component of the equipment, and its performance and stability directly affect the operational efficiency and safety of the equipment. The shaft seal flow switch ensures the normal operation of the shaft seal device by monitoring and adjusting the water flow rate and pressure in real time, thereby improving the operational efficiency and safety of the equipment. 5. Precautions for Use Before installing and starting the shaft seal flow switch, carefully check whether the instrument is installed correctly, whether
