The grease addition system plays a crucial role in compound feed mills by introducing liquid nutrients such as oils and fats into the mixer. This process enhances the palatability of the feed, increases its energy content, and improves overall product quality. As a result, the proper functioning of the grease addition system is essential for maintaining smooth production and consistent product standards. The following text provides an analysis of common faults that may occur during operation, along with troubleshooting methods for reference.
One of the most frequent issues is the system’s inability to spray liquid. This fault typically manifests through increased motor current, excessive drag, loud noises from the fuel injection pump, rising pressure on the pressure gauge, automatic opening of the relief valve, and backflow of liquid into the tank. Additionally, the intelligent flow meter may display error messages. These symptoms often indicate blockages in the pipeline or improper valve operation.
Blockages can occur due to various reasons, including a closed plug valve (including the solenoid valve), clogged nozzles, or low ambient temperatures—especially during winter. When the temperature drops, the oil may become too viscous or even solidify, increasing friction within the pipes. To resolve this, it's important to inspect and repair the solenoid valve, clean or replace the nozzle, ensure all valves are fully open, and consider preheating the pipeline if necessary.
Another common issue involves the solenoid valve losing control. If the valve cannot open, it will block the flow; if it opens but doesn’t close properly, it may cause overfeeding. This can lead to errors in both the solenoid valve and the intelligent flow meter. Faults in the solenoid valve may include a broken coil, an open circuit in the power line, or a damaged return spring. In such cases, replacing the spring or the movable core is usually required.
Regarding the intelligent flow meter, there are three main start modes: manual, high-level control machine, and short-delay terminal. Each mode should function correctly to initiate the flow measurement. If the flow meter fails to start, it could be due to internal faults, communication issues, or problems with the hopper door sensors. Checking the wiring and ensuring all components are functioning properly is key to resolving these issues.
Uneven atomization from the nozzles can also affect the mixing process. Dust particles in the mixer may mix with the grease, forming clumps, while insufficient injection pressure can lead to uneven distribution. Regular cleaning of nozzles, adjusting the overflow valve, and optimizing injection pressure are effective solutions. Reducing pipeline length and improving the overall design can further enhance uniformity.
Inaccurate oil delivery is another concern. Smart flow meters use two methods: closed-loop control and time-based control. For accurate measurements, parameters such as oil density, pulse equivalent, and hourly equivalent must be correctly entered. Miscalculations or interference in the communication lines can lead to discrepancies between the actual and specified oil volume. Adjusting these settings according to the manufacturer’s guidelines ensures reliable performance.
Overall, the grease addition system is vital for maintaining the efficiency and quality of feed production. Regular maintenance, timely troubleshooting, and proper calibration are essential to prevent operational disruptions. By understanding and addressing these common issues, operators can ensure the system runs smoothly and consistently.

What is solar monitoring?
Solar safety camera, also known as solar panel safety monitoring, uses solar energy to supply power for compatible monitoring.
How does the solar surveillance camera work?
Solar powered surveillance cameras use solar panels to harness sunlight and convert it into direct current (DC). The inverter then converts direct current to alternating current (AC), which can then be used to power the solar monitoring.
What happens when it rains or it's cloudy -- can solar surveillance cameras work?
Most solar cameras are also equipped with alternative or backup power supplies, usually rechargeable batteries. The solar panel not only powers the Security Camera, but also charges the battery. When there is no direct sunlight (i.e. at night or in rainy days), the solar powered security camera will be powered by rechargeable batteries. Once there is direct sunlight, the battery will start to charge.
Benefits of Solar Monitoring Cameras
The main advantage of the solar monitoring camera is that the solar panel charges the battery powered camera, creating a renewable power supply. Although a Wi Fi connection is required, these cameras can be used in areas of the home that are difficult to access, such as roofs. For places that are not suitable for using wired security systems, the solar safety monitoring camera provides a reliable choice of security systems without the trouble and additional costs of running cables.
