YG type oil pump
1、 Product Overview:
YG type oil pump is a combination of excellent domestic hydraulic models selected by our scientific and technological personnel in collaboration with domestic water pump experts. It adopts the performance parameters of IS type centrifugal pumps and is ingeniously designed on the basis of general vertical pumps. At the same time, suitable hot water, high-temperature corrosion-resistant chemical pumps, and oil pumps are derived from ISG type pumps according to different operating temperatures, media, etc. This series of products has the advantages of high efficiency, energy saving, low noise, and reliable performance, and meets the standard requirements of JB/T53058-93 of the Ministry of Machinery of China. The products are designed and manufactured according to the international ISO2858 standard.
2、 Usage and application areas:
YG oil pump is used forTransporting non corrosive, flammable, and explosive liquids. The temperature ranges from -20 to 120 degrees Celsius, suitable for industries such as petroleum, textiles, and machinery.

The motor is a Y2 series enclosed self fan air-cooled squirrel cage three-phase asynchronous motor, and the explosion-proof motor is a YB2 series.voltage:380V,phaseThree phase,Frequency: 50Hz (can be 60Hz, etc.),Installation location: indoor or outdoor, protection level: IP54, insulation level: F, installation type: V1.
4、 Advantages:
1. Significant reduction in land area: saving about 30-60% of infrastructure investment.
2. The motor and pump are coaxial: simplifying the intermediate connection structure, and the impeller has good dynamic and static balance, so it runs smoothly and reliably with low vibration and noise.
3. Easy installation: The import and export flanges are the same and on the same horizontal line.
4. No leakage: Adopting corrosion-resistant mechanical seals, there is no serious leakage problem caused by packing sealing, ensuring a clean and tidy operating site. The service life of mechanical seals is over 10000 hours.
5. Wide applicability: flow range from 1.5 to 2650m3/h, head from 7.5 to 150M, caliber from 40 to 500mm, divided into conventional flow type and expansion type; There are a total of 240 specifications for basic and cutting types.

7、 Model meaning:
YG100-250(I)A(B)
YG - Vertical Oil Pump
100-- Inlet and outlet diameter
250- nominal diameter of impeller
(I) Spread flow pattern (without this symbol indicating regular flow)
A (B) - The impeller undergoes the first (second) cutting
8、 YG pump type spectrum for you to choose from, making it easy for you to learn how to select

For example, when the flow rate of the water pump is 25m3/h and the head is 20 meters, we first find 25 (unit: m3/h) on the horizontal axis, and then find 20 on the vertical axis. The two lines converge to form a point, which is the model of this pump. The pump model is ISG65-125

10、 Installation instructions
During installation, the weight of the pipeline should not be borne on the pump body, otherwise it may damage the water pump.
2. The pump and motor are integrated structures that have been calibrated by the manufacturer before leaving the factory, and do not require adjustment during installation, making installation very convenient.
3. The installation must tighten the anchor bolts, and the pump should be inspected at regular intervals to prevent loosening and avoid vibration during pump start-up, which may affect the performance of the pump.
4. In order to maintain convenience and ensure safe use, a regulating valve should be installed on the outlet pipeline of the pump and a pressure gauge should be installed near the pump outlet. For high lift pumps, to prevent water hammer, a check valve should also be installed in front of the pump outlet gate valve to cope with sudden power outages and other power loss accidents, ensuring that the pump operates under optimal conditions.
5. When the pump is used in situations with suction, it should be equipped with a bottom valve, and the inlet pipeline should not have too many bends. At the same time, there should be no air or water leakage to avoid affecting the suction capacity of the pump.
To prevent impurities from entering the pump and blocking the flow path, a filter should be installed before the pump inlet to improve performance.
7. The pump should be tested regularly (usually 15-20 days) for about 1 hour to prevent the shaft from getting stuck and unable to operate in emergency situations.
11、 Instructions for use:
Before startup:
1. The hood should be opened and manually turned to check for flexibility.
2. Open the inlet valve and exhaust valve to fill the pump chamber with water, and then close the exhaust valve.
3. Tap the motor to confirm if the steering is correct.
Run:
1. Fully open the inlet valve and close the outlet pipeline valve.
2. Connect the power supply, and when the pump speed reaches normal, open the outlet pipeline valve and adjust it to the desired operating point.
3. Observe whether there are any abnormal situations after the pump is running. If there are any abnormal situations, stop the pump immediately for inspection, handle them before running again.
Parking:
1. After gradually closing the outlet valve, cut off the power supply.
2. Close the inlet valve.
3. If the ambient temperature is below 0 ℃, measures should be taken to keep warm.
