I. Introduction:
The vacuum pump is a clean vacuum pump that can be operated without oil lubrication and will not pollute the environment and the processed product. Suitable for vacuum drying, vacuum concentration operations, can be widely used in pharmaceutical, chemical, food, medical equipment, printing, book binding, packaging, plastic injection and laboratory and other fields.
Second, the scope of application:
The vacuum pump is a clean vacuum pump that can be operated without oil lubrication and will not pollute the environment and the processed product. Suitable for vacuum drying, vacuum concentration operations, can be widely used in pharmaceutical, chemical, food, medical equipment, printing, book binding, packaging, plastic injection and laboratory and other fields.
Second, the scope of application:
1. Suitable for vacuum pumping of closed systems. Such as vacuum packaging, vacuum forming, vacuum suction.
2. Inlet pressure range: 100Pa~100000 Pa. Outside this range, the vacuum pump exhaust port will have oil mist. Working environment temperature and suction gas temperature should be between 5 °C ~ 40 °C.
3, vacuum pump can not remove water or other liquids. Do not remove explosive, flammable, oxygen-rich, corrosive gases.
4, the general supply of the motor is not explosion-proof, such as the requirements of explosion or other special requirements when the motor must meet the relevant standards.
Third, daily maintenance and maintenance:
Third, daily maintenance and maintenance:
1. Check the position of oil level frequently. If it does not meet the requirements, it must be adjusted to meet the requirements. When operating with a vacuum pump, the oil level is subject to the center of the oil standard.
2. Regularly inspect the condition of the oil and discover that the oil should be replaced with new oil in a timely manner to ensure that the vacuum pump is working properly.
3, the oil change period according to the actual conditions of use and whether it can meet the performance requirements, etc., decided by the user's discretion. When a new vacuum pump is generally used to remove clean and dry gas, it is recommended to change the oil once in about 100 hours of operation. After the ferrous metal powder is not visible in the oil, the oil change period can be appropriately extended later.
4. Under normal circumstances, the vacuum pump shall be overhauled after 2000 hours of operation to check the aging degree of the silicon rubber seal, check whether the exhaust valve piece is cracked, and clean the dirt deposited on the valve plate and the exhaust valve seat. Clean the parts inside the entire vacuum pump cavity, such as rotors, rotors, springs, etc. It is usually cleaned with gasoline and dried. After cleaning the rubber parts, dry it with a dry cloth. Clean the assembly with care and bruises.
5. Conditionally clean up the pipes to ensure that the pipes are unblocked.
6, after the re-assembly should be trial run, generally required to run for 2 hours and change the oil two times, due to cleaning in the vacuum pump will leave a certain amount of volatile matter, to be normal operation, and then put into normal work.
7, check the vacuum pump pipe and joints have no loosening phenomenon. Turn the vacuum pump by hand to see if the vacuum pump is flexible.
8. Add bearing lubrication oil to the bearing body. Observe that the oil level should be at the centerline of the oil mark. The oil should be replaced or supplemented in time.
9. Unscrew the water diversion plug of the pump body of the vacuum pump and inject the water (or feed the slurry).
10. Close the gate valve, outlet pressure gauge and imported vacuum gauge of the outlet pipe.
11. Move the motor to see if the motor steering is correct.
12. Start the motor. When the vacuum pump is running normally, open the outlet pressure gauge and the inlet vacuum pump. After seeing the proper pressure, gradually open the gate valve and check the motor load condition.
13. Try to control the flow rate and lift of the vacuum pump within the range indicated on the label to ensure that the vacuum pump operates at the highest efficiency point in order to obtain maximum energy savings.
14. During the operation of the vacuum pump, the bearing temperature must not exceed the ambient temperature 35C, and the maximum temperature must not exceed 80C.
15. If abnormal sound is found in the vacuum pump, stop immediately to check the cause.
16. When the vacuum pump is to be stopped, close the gate valve and pressure gauge first, and then stop the motor.
17. In the first month of work, the vacuum pump will be replaced with oil after 100 hours. After each 500 hours, the oil will be changed once.
18. Regularly adjust the packing glands to ensure that the drip chambers are in normal condition (in case of drip leakage).
19. Regularly inspect the bushings for wear, and replace them when they are worn out.
20, when the vacuum pump is used in winter season, after parking, it is necessary to screw the lower water release screw plug of the pump body to release the medium. Prevent freezing cracks.
21. When the vacuum pump is deactivated for a long period of time, all the pumps need to be disassembled, the water must be wiped dry, and the rotating parts and joints should be greased and stored properly.
