1. The sharp side of the orifice should face the fluid flow as the inlet end and the flared side as the outlet end. If installed backwards, the display will be much smaller. Solution: Check the orientation of the orifice plate and properly install the orifice plate.
The hydraulic cylinder sealing kit is an important component in the hydraulic system, used to prevent hydraulic oil leakage and protect the pistons and rods inside the hydraulic cylinder.

2. The edge of the orifice plate is worn. If the orifice plate is used for a long time, especially if the measured media is mixed with solid particles and other impurities, it will cause changes in the geometry and size of the orifice plate, if the opening is enlarged or The edge of the opening becomes dull, the measurement pressure difference will become smaller, and the flow display will be lower.
Solution: Reprocess the orifice.
3, transmitter zero drift:
If it is used for a long time, the zero point of the transmitter may drift. If it is negative drift, the display pressure difference will decrease and the displayed flow will also decrease.
Solution: Correct the zero point of the transmitter.
4. If the length of the upper and lower straight pipes is not long enough for the upper and lower straight pipes, the gas will not be fully developed if it is not long enough. This will cause large errors in the measurement result. If there are multiple elbows in the upstream straight pipe, the measurement results of the zombie will be biased. low.
Solution: The transformation of the steam pipe is to ensure that the length of the upstream and downstream straight pipe sections meets the specified requirements. Add a rectifier before the throttling device.
Three-Valve Differential Pressure Transmitter Gas Leak If the high-pressure valve cargo balance valve in the three-valve manifold leaks, the measured differential pressure will decrease, and the measurement result will be low.
Solution: If the high pressure valve in the triple valve group leaks, tighten the valve and replace it if necessary. If the balance valve in the three valve group leaks, tighten the valve and replace if necessary.
Choosing the correct hydraulic cylinder sealing kit can extend the service life of the hydraulic system and improve work efficiency.
The following are some key points for purchasing a hydraulic cylinder sealing kit:
1. Determine the model and specification of the hydraulic cylinder: The size and model of the hydraulic cylinder sealing kit must be completely matched with the hydraulic cylinder, otherwise it may cause poor sealing or damage to the sealing components.
2. Choose appropriate sealing materials: The sealing materials for the hydraulic cylinder sealing kit should be selected based on factors such as the type of hydraulic oil, temperature, pressure, etc. The commonly used sealing materials are fluororubber, Butyl rubber, polyurethane, etc.
3. Choose a reliable supplier: Choose a legitimate hydraulic cylinder sealing kit supplier to ensure product quality and after-sales service.
4. Pay attention to installation and maintenance: Proper installation and maintenance of the hydraulic cylinder sealing kit can extend its service life and reduce maintenance costs.
