2CY horizontal ex-proof gear pump stainless steel gear oil pump high temperature gear oil pump
2CY series gear oil pump|Gear type lubrication pump is mainly used
for conveying lubricating oil in lubricating system in various
mechanical equipment. It is suitable for conveying lubricity below
10°E (75C.ST) and temperature below 80°C. Oil material is also
suitable for conveying corrosive, non-lubricating medium containing
solid particles. If high temperature is required, contact with the
unit can be used with high temperature resistant materials. For the
transportation of non-lubricating oils, beverages, and
low-corrosion water, please use the whole stainless steel gear
pump.
In addition to ordinary motors, this series of gear oil pumps can
also be equipped with explosion-proof motors of the same
specifications according to user needs. Users should propose
explosion-proof grades of explosion-proof motors (KB, B2d, B3d).
Gear oil pump structure description
This product consists of zero parts and components such as pump
body, gear, front and rear pump cover, safety valve, bearing and
sealing device.
1. The pump body, front and rear cover and other parts are gray
cast iron parts, the gears are made of high quality carbon steel;
they can also be made of copper or stainless steel according to
user needs.
2. Safety valve.
The 2CY series gear lubrication pump does not have a safety valve
itself. Users need to install a safety valve in the pipeline system
when using it. KCB, 2CY series gear-type oil pump is equipped with
a safety valve above the rear pump cover or pump body. When the
pump or discharge pipe fails or the discharge valve is completely
closed to generate high pressure and high pressure shock, the
safety valve will automatically open and unload. In addition to
some or all of the high pressure liquid returning to the suction
chamber, it provides a safe protection for the pump and the
pipeline.
3. Bearings.
2CY series gear lubrication pumps all use DU bearings; tin bronze
bearings can be used according to user requirements.
&0818.3-83.3, 2CY1.1 gear type oil pump adopts DU bearing; tin
bronze bearing can be used according to user requirements.
KCB133-960, 2CY8-60 gear type oil pump has three structures: DU
bearing, tin bronze bearing and rolling bearing, which need to be
specified when ordering. Those who are not indicated at the time of
ordering are supplied in accordance with the DU bearing structure.
The bearings are built-in and rely on the medium being conveyed for
lubrication; the 011 bearings and tin bronze bearings work in
non-lubricating media.
4, shaft seal.
The shaft end seals of this series have three structures: skeleton
oil seal, mechanical seal and packing seal.
a. Skeleton oil seal: The skeleton oil seal is characterized by
convenient maintenance and replacement, low cost, and short life.
Dingqing rubber skeleton oil seal is suitable for 1001: the
following working environment; fluororubber skeleton oil seal is
suitable for working environment below 200 °C.
b. 1 Mechanical seal: The mechanical seal is characterized by
reliable sealing, long service life and high cost. The mechanical
seal base is made of stainless steel, and the moving and static
ring-shaped media are made of YG8 cemented carbide or YG8-graphite,
respectively, and the use temperature is below 200 °C.
c. Packing seal: Packing seal is only used for high temperature oil
pump, which is characterized by high temperature resistance and a
small amount of leakage. During the use, it is necessary to adjust
according to the leakage condition. The use temperature is below
250 °C: below.
What type of sealing structure the user needs is specified when
ordering. All those who do not indicate when ordering are supplied
according to the Dingqing rubber skeleton oil seal structure.
5, Inlet and outlet port type:
The inlet and outlet of the 2CY series gear lubrication pump are
the British pipe thread (G) corresponding to the diameter, which is
directly made on the pump body.
KCB18.3-200, 2CY1.1-12 gear type oil pump is equipped with a waist
flange with pipe thread; the other pumps are not equipped with
flanges. When users need to wear flanges, they should be indicated
in the order.
6. The pump and motor are connected by a flexible coupling and
mounted on a common chassis.
Precautions when using
1, installation
a. Before installation, check whether the pump is damaged during
transportation, such as whether the motor is damp, whether the dust
cover of the pump inlet and outlet is damaged, and the dirt enters
the pump chamber.
b. Clean the inner wall of the pipe with clean water or steam
before installing the pipe. When installing, avoid the weight of
the pipeline to be borne by the pump, so as not to affect the
accuracy and life of the pump.
c. The oil pump should be as close as possible to the oil pool; the
joints of the pipelines must not leak or leak, otherwise there will
be no liquid absorption.
d. In order to prevent dirt such as particle shields from entering
the pump, a metal filter should be installed at the suction port
with a filtration accuracy of 30 mesh/in and a filtration area that
is more than three times larger than the cross-sectional area of
the inlet pipe.
e. Import and export pipelines It is recommended to install a
vacuum gauge and a pressure gauge to monitor the working condition
of the pump.
f. When the oil pool is deep, the suction line is long or the
medium viscosity is high and the vacuum is too high, the inlet pipe
can be thickened first. The bottom valve should also be installed
when the suction line is long.
2. Inspection before work
a. Whether the fasteners of the pump are secure.
b. Whether the rotation of the drive shaft is light and heavy.
c. Is the valve in and out of the pipe open?
d. Whether the direction of rotation of the pump meets the
requirements.
e. Inject the appropriate amount of media into the pump before
initial use.
3. Maintenance at work
a. Note that the pressure gauge and vacuum gauge readings of the
pump should be within the specifications specified by the pump.
b. When the pump has abnormal noise or excessive temperature rise
during operation, stop pump check immediately.
c. Under normal circumstances, the safety valve should not be
adjusted arbitrarily. If adjustment is needed, it should be
calibrated with the instrument. Make the shutoff pressure of the
safety valve the pump
d. 1.5-2 times the rated pressure.
4, The pump stops
a. Turn off the power.
b. Close the inlet and outlet piping valves.
