Product details

YG explosion-proof pipeline oil pumpThe import and export flanges are on the same centerlineISG pipeline pumpThe extended product can be directly installed on the pipeline, with a vertical structure and integrated pump, occupying a small area and making installation very convenient. YG type explosion-proof pipelineoil pumpAdopting high-quality mechanical seals, there is no leakage, effectively reducing the oil and gas content in the pump room, improving the working environment, and enhancing the safety and reliability of the pump room operation.

YG explosion-proof pipeline oil pumpWhere are the advantages?

1. YG explosion-proof pipeline oil pump can operate outdoors without building a pump room.
2. The import and export flanges are located on the same centerline and can be directly installed on the pipeline. The vertical structure integrates the machine and pump, occupying a small area and making installation convenient.
3. By using high-quality mechanical seals, there is no leakage at the shaft end, effectively reducing the oil and gas content in the pump room, improving the working environment, and enhancing the safety and reliability of the pump during high operation.
4. The key components are made of high-quality new materials, which improve the reliability and service life of the pump according to the corrosiveness and temperature requirements of the conveying medium.
5. The EX explosion-proof motor with explosion-proof grade dIIBT4 is selected, which has excellent explosion-proof performance.
YG explosion-proof pipeline oil pumppurpose
1. YG explosion-proof pipeline oil pump is suitable for transporting media without solid particles, such as gasoline, kerosene, diesel and other petroleum products, with a temperature range of -20 ℃ -+120 ℃;
2. When the temperature of the transported oil medium T is greater than 120 ℃ or contains trace particles, high-temperature YG explosion-proof pipeline oil pump structure or chemical pump structure can be selected.
Working conditions of YG explosion-proof pipeline oil pump
1. YG explosion-proof pipeline oil pump suction pressure ≤ 1.0MPa, or the maximum working pressure of the pump system ≤ 1.6MPa, that is, the pump suction inlet pressure+pump head ≤ 1.6MPa, the pump static pressure test pressure is 2.5MPa, please specify the system working pressure when ordering. When the working pressure of the pump system is greater than 1.6MPa, it should be separately stated when ordering, so that the overcurrent and connection parts of the pump can be made of cast steel materials during manufacturing.
2. The ambient temperature is less than 40 ℃ and the relative humidity is less than 95%.
3. The volume content of solid particles in the conveyed medium shall not exceed 0.1% of the unit volume, and the particle size shall be greater than 0.2mm.
Note: If the medium used is with small particles, please specify when ordering so that the manufacturer can use wear-resistant mechanical seals.
YG explosion-proof pipeline oil pumpINSTALLATION REQUIREMENTS
1. Before installing the YG explosion-proof pipeline oil pump, the fastening body of the unit should be checked for looseness, and the flow channel of the pump body should be checked for foreign objects to prevent damage to the impeller and pump body during pump operation.
2. The weight of the pipeline should not be added to the water pump during installation to avoid deformation of the pump.
3. The foundation bolts must be tightened during installation to avoid the impact of vibration on pump performance during start-up.
4. For the convenience of maintenance and safety of use, a regulating valve is installed on the inlet and outlet pipelines of the pump, and a pressure gauge is installed near the pump outlet to ensure that it operates within the rated head and flow range, ensuring the normal operation of the pump and extending its service life.
5. After installation, the pump shaft should be moved, and there should be no friction sound or jamming phenomenon of the impeller. Otherwise, the pump should be disassembled to check the cause.
6. There are two types of pump installation: rigid connection installation and flexible connection installation (see connection method).

Start stop specifications
（1） Preparation before starting YG explosion-proof pipeline oil pump
1. Rotate the motor fan blades by hand, and the impeller should have no jamming or grinding phenomenon, and rotate flexibly.
2. Open the inlet valve, open the exhaust valve to fill the entire pump chamber with liquid, and then close the exhaust valve.
3. Manually rotate the pump to allow lubricant to enter the mechanical seal end face.
4. Tap the motor to confirm if the steering is correct.
（2） Start up and operation
1. Fully open the inlet valve and close the outlet pipeline valve.
2. Connect the power supply, gradually open the valve on the discharge pipeline when the pump reaches normal speed, and adjust it to the desired working condition.
3. Pay attention to the instrument readings and check the leakage of the shaft seal. Under normal circumstances, the mechanical seal leakage is less than 3 drops per minute. Check that the temperature rise at the motor and bearing is ≤ 70 ℃. If any abnormal situation is found, it should be dealt with in a timely manner.
（3） Parking
l、 Gradually close the valve of the discharge pipeline and cut off the power supply.
2. Close the inlet valve.
3. If the ambient temperature is below 0 ℃, the liquid inside the pump should be drained to prevent freezing and cracking.
4. If the pump is not used for a long time, it should be disassembled, cleaned, packaged and stored.
YG explosion-proof pipeline oil pump maintenance
（1） Maintenance during operation
1. The imported pipeline must be filled with liquid, and the pump is prohibited from running for a long time in a cavitation state.
2. Regularly check the motor current value and ensure it does not exceed the rated current of the motor.
3. After long-term operation of the pump, if the noise and vibration of the unit increase due to mechanical wear, it should be stopped for inspection, and vulnerable parts can be replaced if necessary. The overhaul period of the unit is generally one year.
（2） Mechanical seal maintenance
1. Mechanical seal lubrication should be clean and free of solid particles.
2. Mechanical seals are strictly prohibited from working under dry grinding conditions.
3. Before starting, the pump (motor) should be turned a few times to avoid sudden starting causing damage to the graphite ring.
4. The allowable deviation for seal leakage is 3 drops/minute, otherwise maintenance should be carried out.
YG explosion-proof pipeline oil pumpFault causes and troubleshooting methods

Fault phenomenon

Possible causes

Troubleshooting

1. The water pump is not producing water

a. The import and export valves are not open, the inlet and outlet pipelines are blocked, and the impeller flow channel is blocked.

b. The motor is running in the wrong direction and has a slow speed due to phase loss.

c. The suction pipe is leaking air.

d. The pump is not filled with liquid and there is air inside the pump chamber.

e. Insufficient imported water supply, high suction, and leaking bottom valve.

f. Excessive pipeline resistance and improper pump selection.

a. Check and remove blockages.

b. Adjust the direction of the motor and tighten the motor wiring.

c. Tighten all sealing surfaces and eliminate air.

d. Open the pump cover or open the exhaust valve to exhaust the air.

e. Shutdown inspection and adjustment.

f. Reduce pipeline bends and reselect pumps.

2. Insufficient water pump flow

a. First, check the cause according to 1.

b. The pipeline and pump impeller flow passage are partially blocked, with scale deposition and insufficient valve opening.

c. The voltage is too low.

d. Impeller wear.

a. First, press 1 to exclude.

b. Remove the obstruction and readjust the valve opening.

c. Stabilize voltage.

d. Replace the impeller.

3. Excessive power

a. Exceeding the rated flow usage.

b. The suction distance is too high.

c. The pump bearings are worn.

a. Adjust the flow rate and turn down the outlet valve.

b. Reduce suction distance.

c. Replace the bearings.

4. Noise vibration

a. The pipeline support is unstable.

b. Liquid mixed with gas.

c. Generate cavitation.

d. The bearing is damaged.

e. The motor is overloaded and heats up during operation.

a. Secure the pipeline.

b. Increase suction pressure and exhaust.

c. Reduce the vacuum level.

d. Replace the bearings.

e. Adjust according to 5.

5. Motor overheating

a. Excessive traffic and overloaded operation.

b. Rubbing.

c. The motor bearings are damaged.

d. Insufficient voltage.

a. Close the outlet valve.

b. Check and eliminate.
