Corrosion resistant chemical pump installed in the installation height is very critical, resistance to corrosion of chemical pump valve in the inlet pipe is not installed on the condition is not higher than the water level must be below the water surface is liquid must be poured into the pump body inside the can, the absorption process is appropriate to control within 6 meters in the valve installed condition.
The reason why the corrosion resistant chemical pump is able to send water out is due to the effect of centrifugal force. Corrosion resistant chemical pump before work, corrosion resistant chemical pump and the inlet tank full of water to form a vacuum, when the impeller rotates fast, rapidly rotating blades to promote water, role of water in rotating centrifugal force from the impeller flew in corrosion resistant chemical pump was thrown out of the water, the central part the impeller formed vacuum region. The water of the water is pressed into the inlet pipe through the pipe network under the action of atmospheric pressure (or water pressure). In this way, continuous pumping can be achieved. It is worth mentioning is that after resistance must be full of water to the pump casing corrosion chemical pump before the start, can start, otherwise the corrosion resistant chemical pump will not be able to finish the imbibition caused by corrosion resistant chemical heat pump, vibration, water, &ldquo, ” idling; damage to the chemical corrosion pump (“ gas bound ”) cause the accident of the equipment.
Calculation method of installation height for corrosion resistant chemical pump
The centrifugal pump allows the suction height of the vacuum height Hs to be the maximum vacuum that can be reached at the inlet pressure of the pump P1.
The Hs value of the centrifugal pump is actually not allowed to be sucked on the vacuum height. It is not the value calculated according to the formula, but the value measured by the pump manufacturer. This value is attached to the pump sample for users to check. It should be noted that the Hs value given in the pump sample is the use of water as the working medium. The operating conditions are 20 C and the pressure is 1.013&times. The value of 105Pa will be converted when the operation conditions and working media are different.
(1) transportation of clean water, but the operating conditions are different from the experimental conditions, which can be converted to the next type.
Hs1 = Hs (Ha10.33) - (Hυ 0.24)
(2) when transporting other liquids, when transporting liquid and villain condition are different from the experimental conditions, we need to do two steps conversion. First step is the Hs1 which is detected in the pump sample based on the upper form, and the Hs1 is converted to H/s by second steps.
