Selection of oil filter: Generally, pollutants with a particle size of less than 10μm have little effect on the pump,hydraulic pump while those with a particle size of more than 10μm, especially above 40μm, have a significant impact on the service life of the pump. The solid pollution particles in the hydraulic oil can easily aggravate the surface wear of the relatively moving parts in the pump. Therefore,hydraulic pump it is necessary to install an oil filter to reduce the degree of oil pollution. Filtration accuracy requirements: 10~15μm for axial piston pump, 25μm for vane pump,hydraulic pump 40μm for gear pump. The contamination and wear of the pump can be controlled within the allowable range. The use of high-precision oil filters is increasingly widespread,hydraulic pump which can greatly extend the service life of hydraulic pumps.
The working principle of a hydraulic pump is a hydraulic component that provides pressurized liquid for hydraulic transmission,hydraulic pump which is a kind of pump. Its function is to convert the mechanical energy of power machines (such as electric motors and internal combustion engines) into liquid pressure energy. The working principle of a single plunger pump. The cam is rotated by a motor.
When the cam pushes the plunger upward, the seal volume formed by the plunger and the cylinder body is reduced,hydraulic pump and the oil is squeezed out of the seal volume and discharged to the place where it is needed through the one-way valve. When the cam rotates to the lower part of the curve, the spring forces the plunger down to form a certain degree of vacuum,hydraulic pump and the oil in the oil tank enters the sealed volume under the action of atmospheric pressure. The cam causes the plunger to rise and fall continuously,hydraulic pump the sealing volume is periodically reduced and increased,hydraulic pump and the pump continuously sucks and discharges oil.
