Description
Hydraulic Piston Pump is an important device in the hydraulic
system. It has the advantages of high rated pressure, compact
structure, high efficiency and convenient flow adjustment. It is
widely used in high pressure, large flow and occasions where flow
needs to be adjusted. In daily use, it should be maintained in a
timely manner in order to make it perform its best function.
The plunger pump that uses the charge pump to supply oil, after
3000 hours of use, the operator needs to check the plunger pump 1-2
times a day to check whether the sound of the hydraulic pump is
normal. If it is found that the speed of the hydraulic cylinder
decreases or the car is stuffy, the charge pump should be
disassembled and checked to check whether the edge of the impeller
is scratched and whether the clearance of the internal gear pump is
too large. For self-priming plunger pumps, the oil in the hydraulic
oil tank should not be lower than the lower limit of the oil mark,
and a sufficient amount of hydraulic oil should be maintained. The
higher the cleanliness of the hydraulic oil, the longer the service
life of the hydraulic pump.
Characteristic
1. The parts constituting the sealing volume are cylindrical
plungers and cylinder holes, which are easy to process and can
obtain high matching accuracy;
2. Good sealing performance, still high volumetric efficiency under
high pressure;
3. The flow rate can be changed only by changing the working stroke
of the plunger, which is easy to realize the variable;
4. The main parts in the plunger pump are all subject to
compressive stress, and the material strength properties can be
fully utilized.
5. Because the plunger pump has high pressure, compact structure,
high efficiency and convenient flow adjustment, it is used in
systems requiring high pressure, large flow and high power and in
occasions where the flow needs to be adjusted, such as gantry
planers, broaching machines, hydraulic presses, construction
machinery , mining metallurgical machinery, ships have been widely
used. According to the arrangement and movement direction of the
plunger, the plunger pump can be divided into two egories: radial
plunger pump and axial plunger pump. There are two types of plunger
pumps in the distribution device, which can be divided into
quantitative plunger pumps and variable plunger pumps according to
whether the displacement is variable.
