Excavators have many components, and hydraulic pumps are one of them.The hydraulic pump is the power component of the hydraulic system, its function is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, which refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system.
The structural forms of hydraulic pumps generally include gear pumps, vane pumps and plunger pumps.
Because the pump is an important part of the machine,we need to choose a high-quality pump to prolong its service life as much as possible, There are many factors affecting the service life of the hydraulic pump, in addition to the design and manufacturing factors of the pump itself, the selection of some elements related to the use of the pump (such as couplings, oil filters, etc.), and the operation during the commissioning process are also related.
Besides ,the choice of brand should also be carefully,The more common brands on the market are Handok, Kawasaki, Nachi,Rexroth,Parker and so on, Now our domestic brands are also guaranteed in quality, such as Xin Tongming, SKS, ZW,etc.
