Product details

2CY gear oil pumpSuitable for transporting various oils such as heavy oil, diesel, and lubricating oil. Equipped with copper gears, it can transport low point liquids such as gas oil and benzene. Our unit also produces stainless steel gear pumps that can transport beverages and corrosive liquids. The 2CY gear oil pump is not suitable for those containing hard particles or fibers, and is suitable for viscosity of 5 * 10-5~1.5 * 103m2/s. The temperature is not high at 70 ℃. If you need to transport high-temperature liquids, please use a high-temperature resistant gear pump, which can transport liquids below 300 ℃.

2CY gear oil pumpWhat are the advantages?

1.2CY gearoil pumpThe structure is simple and compact. It is easy to use and maintain,
The 2.2CY gear oil pump has good self-priming, which means that no liquid needs to be injected before each pump start,
3. The lubrication of the pump is automatically achieved by the conveyed liquid, so there is no need to add additional lubricating fluid during daily operation.
4.2 CY gear oil pump can compensate for small deviations caused by installation by transmitting power through elastic couplings. When the pump is inevitably subjected to hydraulic shock during operation, it can play a significant buffering role.

2CY gear oil pumpInternal structure principle
The 2CY gear oil pump is equipped with a pair of rotating gears in the pump body, one active and one passive, which rely on the mutual meshing of the two gears to divide the entire working chamber inside the pump into two independent parts. A is the suction chamber, and B is the discharge chamber. When the pump is running, the active gear drives the passive gear to rotate. When the teeth shift from meshing to disengagement, a local vacuum is formed on the suction side (A), and the liquid is sucked in. The liquid sucked in fills the various tooth valleys of the gear and is carried to the discharge side (B). When the gear enters meshing, the liquid is squeezed out, forming high-pressure liquid and discharged outside the pump through the discharge port of the pump.
2CY gear oil pumpStructural advantages
The 2CY gear oil pump is a horizontal rotary pump, mainly composed of pump body, gears, bearing seat, safety valve, bearings, and sealing devices.
The pump body, bearing seat, etc. are made of gray cast iron, and the gears are made of high-quality carbon steel. Copper or stainless steel materials can also be used according to the special needs of users.
There is a packing chamber on the bearing seat, which plays an axial sealing role. 2CYl00/3, 2CYl20/3, 2CYl50/3, KCB-300-960 pumps use skeleton sealing devices. The bearing adopts a single row radial ball bearing. KCB-18.3-83.3 pumps are composed of three oil resistant rubber rings and a retaining ring with a middle lining. The sealing degree is adjusted by adjusting the two nuts on the compression cover, and the bearings are copper based powder oil containing bearings. In addition, this series of pumps can all use flexible graphite with good elasticity, high and low temperature resistance, stable chemical properties, and self-lubricating properties as packing for sealing.
The pump is equipped with a safety valve. When the pump or discharge pipeline malfunctions or the discharge valve is accidentally completely closed, resulting in high pressure and high pressure shock, the safety valve will automatically open to discharge some or all of the high-pressure liquid back to the low-pressure chamber, thereby providing safety protection for the pump and pipeline.
Connect the drive motor directly with an elastic coupling and install it on a common cast iron chassis.
2CY gear oil pumpCorrect operation method
install
Before installation, it is necessary to check whether the pump has been damaged during transportation, such as whether the motor has been affected by moisture, whether the dust covers at the pump inlet and outlet are damaged, and whether dirt has entered the pump chamber.
Before installing the pipeline, the inner wall of the pipeline should be cleaned with clean water or steam. During installation, the weight of the pipeline should be avoided from being borne by the pump, so as not to affect the accuracy and service life of the pump.
The oil pump should be as close as possible to the oil tank; The connection parts of the pipeline must not leak air or liquid, otherwise there may be a phenomenon of not being able to absorb liquid.
To prevent particles, impurities, and other contaminants from entering the pump, a metal filter screen should be installed at the suction port with a filtration accuracy of 30 mesh/in, and the filtration area should be more than three times the cross-sectional area of the inlet pipe.
It is recommended to install vacuum and pressure gauges on the import and export pipelines to monitor the working status of the pump.
When the oil pool is deep, the suction pipeline is long, or the medium viscosity is high, causing excessive vacuum, the inlet pipe can be thickened by one gear. When the oil suction pipeline is long, a bottom valve should also be installed.
2CY gear oil pumpPre work inspection
Are the fasteners of the pump secure.
Whether the rotation of the active shaft is uniform and consistent in weight.
Is the valve of the inlet and outlet pipeline open.
Whether the rotation direction of the pump meets the requirements.
Before initial use, an appropriate amount of medium should be injected into the pump.
2CY gear oil pumpMaintenance during work
The readings of the pressure gauge and vacuum gauge of the pump should comply with the technical specifications specified for the pump.
When there is abnormal noise or high temperature rise during the operation of the pump, the pump should be stopped immediately for inspection.
In general, safety valves should not be adjusted arbitrarily. If adjustment is necessary, instruments should be used for calibration. Make the cut-off pressure of the safety valve equal to that of the pump
1.5-2 times the rated pressure.
Stop the pump and cut off the power supply.
Close the inlet and outlet pipeline valves.
2CY gear oil pumpFault cause handling

phenomenon	cause	Troubleshooting
No oil discharge or low oil discharge volume	1. Inhalation height exceeds the rated value 2. Inhalation pipeline leakage 3. The rotation direction is incorrect 4. Suction pipeline blockage or valve closure 5. The safety valve is stuck or scratched 6. Low liquid temperature and increased viscosity	1. Raise the suction liquid level 2. Check all joints, preferably with encrypted sealing materials for sealing 3. Correct in the direction indicated by the pump 4. Check if the pipeline is blocked and if the valve is fully open 5. Disassemble the safety valve, clean it, and grind the valve hole with a finely ground abrasive to ensure a tight fit 6. Preheating liquid or reducing non outlet pressure
Sealing oil leakage	1. Wear of sealing ring 2. Packing seal packing wear 3. Mechanical seal wear or defects such as scratches 4. Mechanical seal spring failure	1. Replace the sealing ring 2. Adjust the tightness of the packing gland to prevent leakage and allow the shaft to rotate; Supplement fillers 3. Replace the dynamic and static rings or regrind them 4. Replace the spring
High noise or vibration	1. Blockage of suction pipe or filter screen 2. The suction pipe extends shallowly into the liquid level 3. Air enters the pipeline 4. The resistance of the discharge pipeline is too high 5. Severe wear of gear bearings or side plates 6. The viscosity of the inhaled liquid is too high 7. Inhalation height exceeds the rated value	1.
