In agricultural production, pumps are the main irrigation and drainage machinery. my country's rural areas are vast, and a large number of pumps are needed in rural areas every year, and agricultural pumps account for more than half of the total pump output. In the mining and metallurgical industries, pumps are also used more equipment. The mine needs to be drained by pumps, and in the process of beneficiation, smelting and rolling, pumps are needed to supply water.
Cavitation corrosion: The corrosion caused by the cavitation of the pump is called cavitation corrosion. A practical and easy way to prevent cavitation corrosion is to prevent cavitation from occurring.
Commonly used dry batteries (such as 1.5V No. 1 battery) have a large internal resistance and provide a small current, and a large part of the voltage is consumed by the internal resistance, so the voltage drops faster, from the power and use time. Considering it is suitable to supply power to a good Kaide vacuum pump.
A water pump is a machine that transports or pressurizes a liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the liquid energy, and is mainly used to transport liquids including water, oil, acid-base liquid, emulsion, suspoemulsion and liquid metal.
In the process of opening and running, you need to pay attention to observe the meter readings, whether the bearing heating, filling water leakage and heating, and the vibration and sound of the pump are normal. If abnormal conditions are found, they should be dealt with in time;
The rusty and uneven surface will reduce the pump water volume by 7%-8%; only need to use a steel brush and iron sandpaper or grinding wheel to smooth the pump, you can reduce the fuel consumption or power consumption during work by 9%-14%.
The water pump heats up: the reason is that the bearing is damaged, the gap between the rolling bearing or the bracket cover is too small, the pump shaft is bent or the two shafts are not concentric; the tape is too tight; the oil is lacking or the oil quality is not good; the balance hole on the impeller is blocked, and the impeller loses balance. Increased the thrust to one side.
After the pump is transported to the installation location, the equipment is hoisted and installed, and it is accurately located on the inertial pedestal of the equipment that has been completed. The concrete strength, coordinates, elevation, size, and bolt hole position of the front foundation must meet the requirements of the detailed design drawing. The anchor bolts should be vertical, tightened, and be in close contact with the equipment base during installation.
The cavitation phenomenon of the pump is caused by the vaporization of water in the pump. The main cause of the cavitation caused by the vaporization of water is related to temperature and pressure. Under a certain pressure, when the temperature rises to a certain value, the water Began to vaporize and transform from liquid to vapor;
