The important part of the plunger pump is the bearing. If there is
play in the bearing, the normal clearance of the three pairs of
friction pairs inside the hydraulic pump cannot be guaranteed. At
the same time, the thickness of the hydrostatic bearing oil film of
each friction pair will be destroyed, reducing the use of the
plunger pump bearing.
According to the information provided by the hydraulic pump
manufacturer, the average service life of the bearing is 10000h,
and it is necessary to replace the new port if this value is
exceeded. Bearings removed can not be detected without professional
testing equipment, and can only be visually inspected.
If scratches or discoloration are found on the roller surface, they
must be replaced.
When replacing bearings, attention should be paid to the English
letters and models of the original bearings. Most of the plunger
pump bearings use large load capacity bearings. Purchase the
original manufacturer and original specifiions. If you replace
another brand, you should consult a person who has experience with
the bearing to look up the table and exchange, the purpose is to
maintain the accuracy level and load capacity of the bearing.
Axial plunger pumps can also use frequency converters to save
electrical energy. In the actual production process, axial plunger
pumps are usually operated under pressure or flow to adjust the
operating state. When the actual pressure is greater than the
required pressure, it is adjusted through the relief valve to keep
its operating pressure stable and let the relief valve release the
excess. The motor has been running at full speed repeatedly, and
the power consumption remains unchanged.
The valve plate has two forms: plane flow distribution and
spherical flow distribution. The friction pair of spherical flow
distribution is repaired by grinding when the scratches on the flow
distribution surface of the cylinder are relatively shallow: when
the groove on the flow distribution surface of the cylinder is
deep, the groove should be filled with surface engineering
technology” before grinding Do not blindly grind to prevent the
copper layer from thinning or oil leakage from the steel base.
When using overflow to adjust the pressure and flow, some of the
excess overflows back to the original system, resulting in the
useless power of the plunger pump and low operating efficiency. If
a Chuangjie energy-saving inverter is used, the overflow valve can
be set Closed, through the energy-saving inverter itself
automatically adjusts the operating pressure to maintain the
stability of the operating pressure, and automatically tracks the
pressure of the device.
Realize automatic control, thereby saving energy consumption. The
biggest advantage of this adjustment method is that it can reduce
the operating energy consumption of the axial piston pump, and the
power saving effect can reach more than 30%.
