    Product Parameters

    Technical Parameters and Model Meaning of YG Type Vertical Explosion-Proof Pipeline Centrifugal Oil Pump:

    　　1. Explosion-proof pipeline pump suction pressure <1.0 MPa, or the pump system's maximum working pressure <1.6 MPa, that is, pump inlet pressure + pump head <1.6 MPa, pump static pressure test pressure is 2.5 MPa. Please specify the system working pressure when ordering. If the pump system working pressure is greater than 1.6 MPa, it should be separately specified when ordering so that the pump's flow parts and connection parts can be made of cast steel during manufacturing.

    　　2. Ambient temperature <40 ℃, relative humidity <95%.

    　　3. The volume content of solid particles in the conveyed medium does not exceed 0.1% per unit volume, particle size >0.2 mm.

    　　Note: If the medium contains fine particles, please specify when ordering so that the manufacturer can use wear-resistant mechanical seals.

    　　2. This explosion-proof pipeline oil pump is mainly used for pipeline boosting and long-distance transportation of gasoline, kerosene, diesel, aviation oil, and other oils. It can also transport other non-corrosive liquids. Suitable for oil depots, gas stations, chemical industry, mining, petrochemical, enterprises, and institutions.

    Structural Diagram and Structural Features of YG Type Vertical Explosion-Proof Pipeline Centrifugal Oil Pump:

    YG Type Vertical Pipeline Pump Structural Diagram

    　　1. The YG type explosion-proof pipeline oil pump has a vertical structure, with the inlet and outlet diameters the same and located on the same centerline. It can be installed in the pipeline like a valve, with a compact and beautiful appearance, small footprint, and low construction investment. With a protective cover, it can be used outdoors.

    　　2. The impeller is directly mounted on the motor's extended shaft, with a short axial dimension and compact structure. The pump and motor bearing arrangement is reasonable, effectively balancing the radial and axial loads generated during pump operation, ensuring smooth operation with very low vibration and noise.

    　　3. The shaft seal uses mechanical seals or a combination of mechanical seals, with imported titanium alloy sealing rings, medium high-temperature mechanical seals, and wear-resistant seals made of hard alloy materials, effectively extending the service life of the mechanical seal.

    　　4. Easy installation and maintenance without dismantling the pipeline system; all rotor components can be pulled out by simply removing the pump coupling seat nuts.

    　　5. The pump can be operated in series or parallel according to flow and head requirements.

    　　6. The pump can be installed vertically or horizontally according to pipeline layout requirements.

    Starting and Stopping of Explosion-Proof Pipeline Oil Pump:

    　　Preparation before Starting:

    　　1. Test whether the motor rotation direction is correct; viewed from the motor top towards the pump, it should rotate clockwise. The test time should be short to avoid dry wear of the mechanical seal.

    　　2. Open the exhaust valve to fill the entire pump body with liquid, then close the exhaust valve after filling.

    　　3. Check whether all parts are normal.

    　　4. Manually rotate the pump to allow lubricating liquid to enter the mechanical seal end face.

    　　5. High-temperature types should be preheated first, with a heating rate of 50℃/hour to ensure uniform heating.

    　　Starting:

    　　1. Fully open the inlet valve.

    　　2. Close the discharge pipeline valve.

    　　3. Start the motor and observe whether the pump operates normally.

    　　4. Adjust the outlet valve opening to the required operating condition. If the user has a flow meter or pressure gauge installed at the pump outlet, adjust the outlet valve opening so that the pump operates at the rated point listed in the performance parameter table; if no flow meter or pressure gauge is installed, adjust the outlet valve opening and measure the motor current to ensure the motor operates within the rated current. Otherwise, the pump will operate overloaded (i.e., high current operation), causing motor burnout. The adjusted outlet valve opening size depends on pipeline conditions.

    　　5. Check the shaft seal leakage; under normal conditions, mechanical seal leakage should be less than 3 drops per minute.

    　　6. Check the motor; bearing temperature should be ≤70℃.

    　　Stopping:

    　　1. For high-temperature types, cool down first at a rate of <10℃/minute until the temperature drops below 80℃ before stopping.

    　　2. Close the discharge pipeline valve.

    　　3. Stop the motor.

    　　4. Close the inlet valve.

    　　5. If stopping for a long time, drain the liquid inside the pump.

    Maintenance of Explosion-Proof Pipeline Oil Pump:

    　　　1. Maintenance during operation:

    　　(1) The inlet pipeline must be filled with liquid; long-term operation under cavitation is prohibited.

    　　(2) Regularly check the motor current value; it must not exceed the motor's rated current.

    　　(3) After long-term operation, due to mechanical wear, if noise and vibration increase, stop and inspect. Replace worn parts and bearings if necessary. The general overhaul period is one year.

    　　2. Mechanical Seal Maintenance

    　　(1) Mechanical seal lubrication should be clean and free of solid particles.

    　　(2) Mechanical seals must not operate under dry friction conditions.

    　　(3) Before starting, manually rotate the pump (motor) several turns to avoid sudden start causing graphite ring breakage.

    　　(4) Allowed seal leakage is 3 drops per minute; otherwise, inspection is required.

    Q

    Can you help me choose a model?

    A

    Of course! If the water pump model is not selected accurately, it can cause significant problems. After you take it back, it might be either too small to meet the usage requirements or too large, resulting in higher electricity and fuel costs, increasing the operating expenses.

    Q

    Why is the price quotation so slow?

    A

    Because centrifugal pumps are non-standard custom products with many models and a wide price range. Even for the same model, the price varies greatly depending on the materials and configurations used. Taking the most common pump accessory—the impeller—as an example, the price of a stainless steel impeller is several times that of a cast iron impeller. Therefore, we need to clearly confirm the relevant information to provide you with an accurate price. Normally, if you provide comprehensive information, we can quote within 5 minutes.

    Q

    What information should I provide when I need a quote?

    A

    Usually, if you want to get an accurate quote, it is recommended that you provide us with the following information: pump flow rate, head, on-site operating voltage, frequency, temperature of the conveyed liquid, pH value, solid particle content, on-site installation conditions (horizontal or vertical installation), and other related details. If you are not very familiar with these, it’s okay; our sales manager will assist you in determining them.

    Q

    Do you have centrifugal pumps in stock?

    A

    There are many models and configurations of centrifugal pumps. Except for a small number of commonly used standard models that are in stock, the vast majority of models and configurations are not stocked and are customized products. We need to first select the pump based on your site conditions such as flow rate, head, medium temperature, pH value, and installation conditions. After determining the pump model and configuration, we can then place an order with the workshop for production.

    Q

    What is your usual delivery time?

    A

    Models in stock can be shipped by the next day at the latest. Others are custom-made, and depending on the product size and specific project conditions, the delivery time is generally between 7-90 days. Please consult our sales manager for details: 0731-88632200 。
