Complies with the latest national standard requirements of JB/T53058-93 of the Ministry of Machinery. The product is designed and manufactured according to the international ISO2858 standard.

Main characteristics of high-temperature oil pump
1. It is a vertical structure with the same inlet and outlet diameters and located on the same centerline. It can be installed in pipelines like a valve and is equipped with an
Bottom foot installation increases the stability of the pump, with a compact and beautiful appearance, small footprint, and low construction investment.
2. The impeller is directly installed on the extended shaft of the motor, with a short axial dimension and compact structure. The pump and motor bearings are reasonably configured, which can effectively balance the radial and axial loads generated by the pump operation, ensuring smooth pump operation and low vibration noise.
3. The shaft seal adopts mechanical seal or a combination of mechanical seals, using imported titanium alloy sealing rings, medium-sized high-temperature resistant mechanical seals, and hard alloy seals
Gold material, wear-resistant seal, can effectively extend the service life of mechanical seals.
4. Easy installation and maintenance, no need to disassemble the piping system, simply remove the pump coupling nut to extract all rotor components.
5. Pumps can be operated in series or parallel according to the requirements of flow rate and head.
6. Vertical and horizontal installation of pumps can be adopted according to the requirements of pipeline layout.

Main purpose of high-temperature oil pump
1. ISG type vertical pipeline centrifugal pump is used for conveying clean water and other liquids with physical and chemical properties similar to clean water. It is suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden sprinkler irrigation, fire protection pressurization, long-distance transportation, HVAC refrigeration cycle, bathroom and other cold and warm water circulation pressurization and equipment matching. The operating temperature is T ＜ 80 ℃.
2. The IRG type hot water pipeline circulation pump is widely used in energy, metallurgy, chemical, textile, papermaking, hotels, restaurants and other boiler high-temperature hot water pressurized circulation transportation and urban heating system circulation pumps. The IRG type uses a temperature T<120 ℃, and the GRG type uses a temperature T<240 ℃.
3. IHG type vertical chemical centrifugal pump is used for conveying liquids that do not contain solid particles, are corrosive, and have a viscosity similar to water. It is suitable for industries such as petroleum, chemical, metallurgical, power, papermaking, food and pharmaceutical, and synthetic fiber. The operating temperature ranges from -20 ℃ to 120 ℃.
4. YG type vertical pipeline centrifugal oil pump is used to transport petroleum products such as gasoline, kerosene, diesel, etc. The temperature of the transported medium is -20 ℃~+120 ℃.
Note: The suction pressure of the pipeline pump is ≤ 1.0MPa, or the maximum working pressure of the pump system is ≤ 1.6MPa, that is, the suction inlet pressure+pump head is ≤ 1.6MPa, and the static pressure test pressure of the pump 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. The ambient temperature is less than 40 ℃ and the relative humidity is less than 95

Preparation and operation before starting the high-temperature oil pump
Preparation before starting:
1. Test whether the motor rotation is correct. When viewed from the top of the motor towards the pump, it rotates clockwise. The test time should be short to avoid dry grinding of the mechanical seal
Loss.
2. Open the drain valve to fill the entire pump body with liquid, and then close the exhaust valve when it is full.
3. Check if all parts are normal.
4. Manually rotate the pump to allow lubricant to enter the mechanical seal end face.
5. High temperature type should be preheated first, with a heating rate of 50 ℃ for hours to ensure uniform heating of all parts.

start:
1. Fully open the inlet valve.
2. Close the valve of the discharge pipeline.
3. Start the motor and observe if the pump is running correctly.
4. Adjust the opening of the outlet valve to the desired operating conditions. If the user has a flow meter or pressure gauge installed at the pump outlet, the opening of the outlet valve should be adjusted
Run the pump at the rated point listed in the performance parameter table. If the user has a flow meter or pressure gauge installed at the pump outlet, the motor current of the pump should be measured by adjusting the outlet valve opening to ensure that the motor operates within the rated current. Otherwise, it will cause the pump to operate at overload (i.e. high current operation) and cause the motor to burn out. The opening size of the outlet valve that is adjusted correctly is related to the working conditions of the pipeline.
5. Check the leakage of the shaft seal. Normally, the mechanical seal leakage should be less than 3 drops per minute.
6. Check that the temperature rise at the motor and bearings is ≤ 70 ℃.
parking:
1. The high-temperature type needs to cool down first, with a cooling rate of less than 10 ℃/minute, and then lower the temperature to below 80 ℃ before parking.
2. Close the valve of the discharge pipeline.
3. Stop the motor.
4. Close the inlet valve.
5. If parking for a long time, the liquid in the pump should be drained completely.
Reasons and Solutions for High Temperature Oil Pump Malfunctions

Installation instructions for high-temperature oil pump
1. Before installation, check if the fasteners of the unit are loose and if there are any foreign objects blocking the pump body flow channel to prevent damage to the impeller and pump during operation
Body.
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 each inlet and outlet pipeline of the pump, and a pressure regulator is installed near the pump outlet
To ensure the operation within the rated head and flow range, to ensure the normal operation of the pump, and to extend the service life of the pump.
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
