When we see the water control industry, we will think of pump products. There are many types of pumps. How to make the pump run safely is more important. It is necessary to make the machinery work for you seriously. It is the key to the pump installation and protection. Introduce device skills in terms of device usage.
The technical skill of the centrifugal pump is to confirm the height of the pump unit. This height refers to the vertical distance from the water source to the centerline of the pump impeller. It is not comparable to the allowable vacuum height. The allowable vacuum height indicated on the pump nameplate or product manual refers to the vacuum value on the pump inlet section. Is at 1 standard atmosphere;
When the water temperature was 20 degrees Celsius, the experiment was carried out. It does not consider the flow of water after the suction pipe is matched.
The slurry pump and the height of the centrifugal pump device should be the part of the remaining value that allows the suction vacuum height to be deducted from the lost lift of the suction pipe. It must overcome the actual groundwater absorption height. The height of the pump unit should not exceed the calculated value. Otherwise, the pump will not be able to pump water.we are gravel pump for sale,you can know it.
In addition, the influence of the accounting value is the loss of the suction pipe of the suction pipe. Therefore, it is advisable to use the shortest pipe arrangement and minimize the installation of elbow fittings. It is also conceivable to equip the pipe with a larger diameter to reduce the flow rate inside the pipe.
When the elevation and water temperature of the pump unit address are different from the experimental conditions, such as the local altitude above 300 meters or the water temperature of the pumped water exceeds 20 degrees Celsius, the slurry pump will be corrected. That is, the atmospheric pressure at different elevations and the full steam pressure above 20 degrees Celsius. However, when the water temperature is below 20 degrees Celsius, the full steam pressure is negligible.
From the skill of the pipeline installation, the suction pipe requires strict sealing, and it cannot leak or leak water. Otherwise, the vacuum at the water inlet of the pump will be destroyed, so that the water output of the pump will be reduced, and even if it is serious, the water will not be pumped. Therefore, the slurry pump should carefully do the interface work of the pipeline to ensure the construction quality of the pipeline connection.
The pump industry is producing a slurry pump together with improved quality: corrosion resistance, acid resistance and wear resistance.
