Multistage High Pressure Water Pump is suitable for water supply and drainage in mines, factories, and cities. They are used to transport clean water without solid particles or liquids with physical and chemical properties similar to clean water, and have a wide range of applications and areas. Equipment shaft seals generally use packing seals, and mechanical seals can also be used according to user needs. The direction of equipment operation is clockwise when viewed from the motor end to the pump. How to use mining multi-stage pumps safely and efficiently? This is a question that many initial users often ask.
First of all, let's introduce from the pump itself: the pump has a good sealing performance - the static joint surface between the water inlet section, middle section and water outlet section is sealed with Molybdenum disulfide, and it is also sealed with paper gasket. After disassembly, it must be sealed with raw materials when reassembling. In order to prevent water from entering the bearings at both ends, "O" type rubber rings and water retaining rings are used for sealing. The rotating and fixed parts of the pump are sealed by a sealing ring, guide vane sleeve, and packing. Water with a certain pressure is introduced into the packing chamber, which serves as a water seal and cooling effect. During operation of the Multistage High Pressure Water Pump, it is important to pay attention to the following points:
1. Observe the Ammeter, listen to the sound, and judge whether the operation is normal;
2. Pay attention to observing whether the motor is overloaded, and it is strictly prohibited for the motor to run over current;
3. Observe the leakage situation at the shaft seal and adjust it. Sometimes, it is necessary to adjust the injection water to ensure continuous dripping;
4. Check if the oil ring of the sliding bearing rotates. The temperature of rolling bearings should be less than 75 ℃;
5. Regularly check the gap between the two couplings, and replace the balance device when approaching close proximity;
6. Observe the outlet temperature of the balance pipe. When the water temperature rises rapidly, the pump should be stopped to check if the balance pipe is blocked;
7. Observe the pressure gauge and vacuum gauge, and promptly identify the cause when the gauge pressure of both is abnormal;
8.观察前的水位vent no-load;
9. When the water level is low, pay attention to whether there will be suction into the pump at the two shaft seals;
10. Pay attention to the operating conditions and cooling water conditions of the pump.
It should also be noted that Multistage High Pressure Water Pump should not operate for a long time with the outlet valve fully closed; It should not operate at the hump in the performance curve. During operation, it should be ensured that the valves on the inlet pipeline are fully open. The valve should not be closed for a long time during startup. Do not exceed 2-3 minutes, otherwise, the temperature rise may cause vaporization and damage the water pump.
