16 maintenance methods of the hottest roots pump

There are 16 maintenance methods for Roots pump

1. Check the oil level frequently. If it does not meet the requirements, adjust it to meet the requirements When the roots pump is running, the oil level shall be subject to the center of the oil level gauge

2, the oil change period is considered according to the actual service conditions and whether it can meet the performance requirements, which is at the discretion of the user Generally, when the new roots pump is pumping clean and dry gas, it is recommended to change the oil every 100 hours When ferrous metal powder is not visible in the oil, the oil change period can be extended appropriately in the future

3, check the oil quality frequently. If the oil is deteriorated, replace it with new oil in time to ensure that the roots pump works normally

4. Generally, roots pump should be overhauled after 2000 hours of operation, check the aging degree of rubber seal, check whether the exhaust valve disc is cracked, and clean up the dirt deposited on the valve disc and exhaust valve seat Clean the parts in the whole roots pump cavity, such as rotor, rotor, spring, etc It is usually washed with gasoline and dried Clean the rubber parts and wipe them dry with a dry cloth When cleaning and assembling, handle with care to avoid bumping

5, add bearing lubricating oil into the bearing body, observe that the oil level should be at the center line of the oil standard, and the lubricating oil should be replaced or supplemented in time

6, check the roots pump pipeline and joint for looseness Turn the roots pump by hand to see if it is flexible

7, the test run should be carried out after reassembly. Generally, it must run empty for 2 hours and change the oil twice, because a certain amount of volatile substances will be left in the roots pump during cleaning, and it can be put into normal operation after normal operation

8, start the motor. When the roots pump operates normally, open the outlet pressure gauge and the inlet roots pump. After it shows appropriate pressure, gradually open the gate valve and check the motor load at the same time

9, try to control the flow and head of roots pump within the range indicated on the label, so as to ensure that roots pump operates at the highest efficiency point, so as to obtain the maximum energy-saving effect

10, when roots pump is to be stopped, close the gate valve and pressure gauge first, and then stop the motor

11, during the operation of roots pump, the bearing temperature shall not exceed the ambient temperature of 35C, and the maximum temperature shall not exceed 80C

12, within the first month of operation, the lubricating oil of roots pump shall be changed once every hour after 100 hours

13, adjust the packing gland frequently to ensure that the leakage in the packing chamber is normal (it is appropriate to form a drip consisting of upper and lower copper plates)

14, regularly check the wear of the shaft sleeve, and replace it in time after heavy wear

15, roots pump is out of service for a long time, so it is necessary to complete the pump and it is the most economical and reasonable process scheme; At the same time, disassemble and wipe dry the water. 2. Type inspection: coat the rotating parts and joints with grease, install them, and keep them properly
