Guide for use, installation and maintenance of hydraulic motors
1. Matters needing attention
1.1 Output steering (with photos)
1.2 The correct use of the hydraulic motors will directly affect
the working life. Therefore, the following basic
requirements must be met.
1.2.1 System requirements
The system should be equipped with a corresponding oil filter to
ensure the cleanliness of the system oil.
The hydraulic circuit must be equipped with a cooling system to
prevent excessive oil temperature.
Pressure gauges and thermometers must be installed in the oil inlet
lines.
A pressure gauge should be installed in the hydraulic circuit of
the hydraulic pump.
1.2.2 System hydraulic oil requirements
According to the different ambient temperature and usage, the oil
used should have good viscosity
temperature performance, good defoaming properties, anti-oxidation,
anti-rust, high flash point, etc. During the
operation of the motor, its viscosity is between (25-70)*10-6m2/s,
and the water, alkali and mechanical
impurities in the oil must not exceed the allowable value.
It is recommended to use YB-N46, YB-N68 anti-wear hydraulic oil.
The filtration accuracy of the system is better than 20μm.
Normal working oil temperature is 25-55℃, short-term working oil
temperature is not higher than 65℃.
2. Hydraulic Motors installation
Before installation, check whether the motor is damaged. The motor
oil stored for a long time needs to be
drained and rinsed to prevent the internal moving parts from
sticking.
The motor mounting bracket must have sufficient rigidity to prevent
shock and vibration during rotation.
The mounting bolts must be tightened evenly.
Connection method of drain pipe:
The BMR motor has two built-in check valves, and the leaked oil can
return to the oil return pipe through the
check valve, (with photos)
A) When the oil return pressure is ≤1Mpa, there is no need to
connect the drain pipe;
B) When the oil return pressure is greater than 1Mpa, the drain
pipe must be connected. (Drain pipe location
diagram)
The motor is unstable when running at low speed and can be
eliminated by applying back
Pressure, the back pressure value is not less than 0.2 Mpa
This type of hydraulic motors can not be operated under the pump
working conditions, nor can it be
used as a pump
The installation surface should be flat
The installation should determine the connection flange, the stop,
and the output connection
shaIt size is accurate.
Ensure that the output shaft and the device onnected to the
transmission have good
concentricity. When the output shaft is installed, it is necessary
to prevent the axial thrust of
the output shaft and the interlocking devide. ( the hydraulics
motors BMR bears a small radial
force.)
During the installation process, the smoothness and parallelism of
the connecting plate part
of the oil inlet and outlet are protected to prevent the oil
sealing effect caused by the pumps
from being bad, resulting in oil leakage
The screws and the rear cover of the rear of the hydraulic motors
must not be hit during
installation. If you want to tap, please tap the mounting flange (
with photos )
The motor cannot be installed forceIully or twisted.
Do not remove the plastic plugs above the Spiplines and oil pipes
before they are installed
When the system is connected, the relationshpS between the
installation position of the hydraulic motors
inlet and outlet on the installation drawing and the rotation oI
the hydraulic motors should be recognized
During the installation, it was found that the oil inlet and outlet
are not suitable Ior the
corresponding positive and negative rotation directions oI the
output shaft. Replacing the
installation of the oil inlet and outlet pipes for the A and B
chambers can achieve the opposite
effect to the original working rotation direction.
3. Use of the hydraulic motors
3.1 Use of hydraulic motors
The pressure, flow and output power of the hydraulic motors must
not exceed the specified values.
When running for a long time, the oil temperature dose not exceed
65 ℃
Motor limit working temperature: -30℃ - 70 ℃
3.2 Commissoning
Before starting, check the hydraulic motors installation, whether
the connection is correct and firm and the system is correct
Check whether the oil inlet and outlet directions and hydraulic
motors rotation direction meet the requirements of working
conditions
The pressure of the relief valve of the oil supply line is adjusted
to the lowest value, and gradually adjusted to the required
pressure
after opration. Tighten the inlet and outlet pipes and the drain
pipe.
After running the motor under no load for at least 10 minutes,
gradually increase the pressure to the working pressure,
and observe whether the hydraulic motors is running mormally at any
time during the operation
During operation, the working conditions of the hydraulic motors
and system should be checked frequently.
If abnormal temperature rise, leakage, vibration and noise or
abnormal plusation of pressure are found, the machine should
be stopped immediately to find our the cause.
During use, when the temperature of the oil inlet is >=65 ℃,
please check whether the cooler works normally.
To ensure the mormal working temperature of the hydraulic motors
surface.
Motor transportation should be equipped with appropriate wooden
boxes and cardboard boxes according to the size of the hydraulic
motors and plastic paper packaging on the surface of the hydraulic
motors to prevent the moisture and moisture from invading the
hydraulic motors and causing the hydraulic motors to rust and cause
hydraulic motors failure.
Avoid placing the hydraulic motors directly on the fround, No need
to apply anti-rust oil for a long time
Hydraulic motors storage envionment: 10-9%RH, -20 - 65SC.
During transportation and storage, the hydraulic motors should
avoid moisture.
