Knowledge of using horizontal pipeline centrifugal oil pump:
Preparation before startup
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 causing mechanical tightness
Seal and wear.
2. Open the exhaust 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 ℃/hour 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 outlet should be adjusted by adjusting it
The valve opening allows the pump to operate at the rated point listed in the performance parameter table. If the user has a flow or pressure gauge installed at the pump outlet, it should
By adjusting the opening of the outlet valve and measuring the motor current of the pump, the motor can operate within the rated current, otherwise it will cause the pump to overload
Run (i.e. high current operation) until the motor burns 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 should first cool down, 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.
Installation Instructions for ISWHB Stainless Steel Horizontal Centrifugal Oil Pump
1. Before installation, check if the fasteners of the unit are loose and if there are any foreign objects blocking the flow channel of the pump body to avoid damaging the blades during the operation of the water pump
Wheel and pump 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, install one regulating valve on each inlet and outlet pipeline of the pump, and install one near the pump outlet
Only pressure gauges are used to ensure operation within the rated head and flow range, ensuring the normal operation of the pump and increasing 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).
