Lincoln automatic lubrication system maintenance and troubleshooting common problems

Lincoln automatic lubrication system has provided lubrication protection for construction machinery and mining machinery for more than a century

Lincoln quicklub progressive system and Centro matic single line lubrication system have become the lubrication standards of construction machinery and mining machinery industry

users of construction machinery and mining machinery all over the world choose Lincoln lubrication system, which is attributed to its reliable performance and wide application under severe working conditions

in view of the problems encountered by users in practical applications, we summarize the following points:

1) the fault lubrication pump does not output oil

reasons:

· the oil tank is empty

· bubbles in the grease

· the oil inlet of the pump core is blocked

· the pump in China is still in the process of industrialization, information dissipation, urbanization, marketization During the deep development stage of internationalization, the core is worn

· the one-way valve of the pump core is invalid or blocked

treatment:

· fill oil into the oil tank and start the lubrication cycle until the oil injection at each lubrication point is normal

· start the lubrication cycle, loosen the connection between the safety valve and the main pipe until there are no bubbles in the grease

· take out the pump core, check the sundries at the oil inlet of the pump core and clean it

· replace the pump core

· replace or clean the pump core

2) fault: the downstream pipeline of the progressive distributor is blocked

cause:

· the distributor is blocked

· the pipeline from the distributor to the lubrication point is blocked or the bearing is blocked

treatment:

· replace the distributor or clean it according to the manual

· clean the blockage of the pipeline or check and clean the bearing

3) fault: the pump is running, but the oiler does not operate

reason:

principle · low system pressure

· empty oil tank

· there is air in the pump or main pipeline

treatment:

1) ensure that the air pressure or hydraulic pressure of the pump is set correctly

2) if the supervisor has leakage, check and eliminate the leakage

3) the oiler is worn or damaged, repair or replace it

· fill the oil tank

· exhaust the pump or main pipe

4) fault: the pump is running, and only some oilers act

reason:

· low system pressure

· empty oil tank

· there is air in the pump or main pipeline

· the system is not fully depressurized

· the wrong type of oiler is installed on the system

treatment:

· increase the system pressure, and check the pressure of the oiler farthest from the pump

· fill the oil tank

· exhaust the pump or main pipe

· check the system pressure at the intermittent time to ensure that the system pressure is low enough for all injectors to recycle

· ensure that all oilers are correct

5) fault: the pump stops running before all oilers act

reason:

· the setting of pump running time is too short

· the position of pressure switch is too close to the pump

· system pressure is too low

fault:

· increase the running time of the pump

· set the pressure switch to the farthest end of the pipeline

· increase the system pressure and check the oiler at the farthest end of the pipeline

6) fault: at the end of all oiling, people in the industry said that the device completed the cycle, the pump could not stop, and the controller gave an alarm

reason:

· the pressure switch was not set correctly according to the decision-making procedures of listed companies at that time

· there was no electrical connection between the pressure switch and the controller

· the pressure switch was damaged, worn or blocked

processing:

· adjust the pressure switch to the correct pressure

· repair the electrical connection of the pressure switch

· repair or replace the pressure switch

7) fault: the oiler does not discharge oil

reason:

· the oil discharge of the oiler has been adjusted to the minimum

· the pipeline is blocked or the bearing clearance is too tight

· the oiler spring is damaged or worn

· injector plunger wear

· injector check valve leakage or blockage

treatment:

· adjust the oil discharge of the injector

· clean the blockage or check the bearing

· replace the spring

· replace the oiler

· replace the sealing ring or clean up sundries
