Hydraulic system in the operation process will produce impurities, metal particles, etc., if not cleaned up in time, dirt, sludge and other pollutants will also accumulate inside the hydraulic system, which will have many adverse effects on the normal operation of the hydraulic system. This article will take the hydraulic pump suction port clogging as an example, for you to introduce in detail to identify and deal with such problems.
When the hydraulic pump suction port is clogged, it will often show some obvious signs, such as: pressure drop, noise increase, temperature increase, system efficiency is reduced, system efficiency is reduced, and so on.
Pressure Drop: If the suction port is clogged, the hydraulic pump may not be able to draw enough fluid, resulting in a drop in system pressure. This may be reflected in the pressure gauge or shown by sluggishness and weakness in the operation of the equipment.
Increased noise: A clogged suction port can cause the hydraulic pump to have difficulty drawing in oil, which may cause the pump to make unusual noises, such as sucking or cacophonous noises, during operation.
Increased temperature: As the hydraulic pump constantly struggles to draw in oil but is unable to get enough, this may cause the pump to overheat, which in turn increases the temperature of the entire system.
Reduced working efficiency: Due to insufficient oil supply, the working efficiency of the whole hydraulic system will be reduced, which will be manifested as slower running speed of the equipment and incoherent action of the executive elements.
Prolonged insufficient oil suction will lead to excessive wear and tear inside the hydraulic pump, which may eventually lead to pump damage if the problem is ignored. And when the suction port is obstructed, it may cause air to enter the hydraulic system, thus forming air bubbles in the fluid, and these air bubbles flowing in the system may cause vibration and noise.
Solutions to these common failures include regular inspection and maintenance of the hydraulic system, replacement of seals and hydraulic oil, strengthening equipment operation and maintenance, and the establishment of a sound equipment management system. Daily attention should be paid to cleaning the hydraulic components, cleaning can be done in accordance with the following steps:
(1) selected cleaning oil: when the system piping tank is cleaner, you can use the same viscosity with the working fluid or the same kind of oil cleaning; such as found in the system is not too clean, you can use a slightly lower viscosity cleaning oil for cleaning.
(2) heating cleaning oil: hot oil so that the system is easy to free off the adherents, cleaning oil flow rate as large as possible, in order to help take away the dirt.
(3) Installation of filters: In the cleaning circuit, the inlet is installed with a 50-100μ coarse filter, and the return port is installed with a 10-50μ filter. At the beginning of the coarse filter, rinse for a period of time and gradually change to a fine mesh oil filter, filtering in stages. Seriously contaminated equipment is first cleaned with low-viscosity oil with good washing effect, and then cleaned with cleaning oil with similar viscosity to the used oil.
(4) Tapping with a wooden hammer while cleaning can promote the speed of pollutant shedding. Pipe bending and welding parts should be knocked more, but not too hard to avoid pipe deformation and rupture.
(5) discharge cleaning oil and add new hydraulic oil: cleaning oil excluded, should be added as soon as possible to the new hydraulic oil, and immediately carry out a short test run, so as to avoid corrosion in the pipeline and other adverse effects.
