The vacuum conveying equipment produced by Shanghai Donggeng Engineering Technology Co., Ltd. is imported from Germany today. It uses a multi pole Venturi tube vacuum pump to generate negative pressure to transport materials from one location to another through pipelines. The entire conveying process is completed in a closed state, eliminating the harm caused by dust to the working environment, surrounding environment, and operators. It is suitable for industries such as food and chemical.
As a dust-free conveying equipment, the vacuum feeder is a conveying device used in the powder industry for material transportation in various links, so its frequency of use is very high. Some devices are prone to malfunctions after prolonged use. Therefore, as the technical leader. We should strive to solve problems within time to avoid production issues caused by equipment failures and delays in production.
Inspection steps: Check the power source. Touch screen manual testing interface for vacuum feeding equipment, start the vacuum pump, and observe whether the vacuum gauge and pressure relief port airflow are normal. In addition, it is also necessary to check whether the vacuum degree and gas flow rate meet the requirements. If the vacuum degree exceeds the normal value, there may be material blockage in the surface conveying pipeline of the equipment; When the vacuum degree is lower than the normal value, there will be air leakage on the surface of the equipment.
Step 2: Check the sealing of the pipeline. After starting the vacuum feeding equipment, check if there is suction at the feeding port. Check for material blockage in the absence of suction, check for filter blockage in the presence of low suction, and check for air leakage in the pipeline.
Step 3: Check the sealing ring of the butterfly valve. As a moving part of the feeding machine, the butterfly valve is inevitably worn out after long-term use. If there is air leakage, it may be due to low vacuum degree, slow suction, or direct failure to suction at the site. At this point, the feeding machine cover should be opened to observe if the sealing ring is worn. If there is wear and tear, it should be replaced in a timely manner.
Step 4: Check if the feeding machine operates normally. According to the working principle of the feeding machine, rule out whether the actions of each butterfly valve are normal one by one. Check if the compressed air pressure is sufficient. This probability is extremely low, and it cannot be ruled out that compressed air may contain excessive impurities that can damage solenoid valves and cylinders.
In addition to troubleshooting and inspecting vacuum feeding equipment, it is also crucial for users to carry out daily maintenance, cleaning, and upkeep of the feeding machine. The author has compiled three steps for maintenance and upkeep.
Maintenance steps: Before starting up, conduct a preliminary inspection of the vacuum feeding equipment. Mainly check whether the suction valve, pipe joints and other related parts of the vacuum pump are sealed. Only with good sealing can the equipment ensure that it will not malfunction during subsequent work, enabling stable operation.
Step 2 of maintenance: Observe the internal working condition of the feeding machine. Once abnormal conditions or a decrease in internal vacuum occur, the machine should be stopped in a timely manner and inspected. If any damaged parts are found, they should be replaced immediately. In addition, vacuum pumps also need to be cleaned at all times to keep the inside of the pump clean.
Step 3 of maintenance: After the equipment is used up, it is necessary to pay attention to cleaning the feeding machine comprehensively and inspect all components.
