introduction：Most greases are stored for a period of time，consistency（It refers to the measurement value of conical degree）Hardening can occur in the variable assembly，If not more1A consistency number，Ready to use，Does not affect the general lubrication。If the consistency changes greatly，It means that the base oil is too much，It will harden slowly，May increase the friction resistance of mechanical parts during lubrication、Increased consumption of mechanical power，Not suitable for direct use。Some people add base oil to the hardened grease to dilute it，Makes the lipid scheduling smaller（Instant softening）After use，This approach is not recommended。Because of the lack of necessary homogenization work，The colloidal stability of grease becomes poor。Grease that has thickened，Other physical and chemical properties change little，The same base oil can be added at the production plant。After homogenizing work treatment and analysis and testing qualified，It can be used。

introduction：The level controller power should be matched with the motor。The reason is that the switching signal output of the level controller generally has only a small current through it（Milliampere level），Then the power in the start and operation of the motor is very large amperage（Ann），Then directly use the level controller to control the operation of the motor at stop will directly burn to the level controller。The solution is between the level controller and the motor，Add a relay，That way there wont be a lot of trouble，And affect the normal life of the level controller。
