The general self suction pump in the transportation of liquid when the liquid level is lower than when we need to pump irrigation water required for installation of the pump inlet valve. At the end of the valve a long time corrosion or by blocking the need for exchange or repair is very easy to use. The submersible pump is usually used to transport water and water, and it is unsafe for corrosion and leakage of motor under the condition of acid and alkali and other corrosive liquids. So it made the expanse and the fluid transport pump to be low, the liquid pump to solve the issue of low transmission due to the long axis combined with uneven impeller radial force of the shaft has a cantilever structure, the rotation of the impeller end of the deflection caused a great deal, the longer axis, the deflection is larger, in order to bearing the entire root axis for the flexible bearing wear under constant unilateral mounted on the shaft to solve this problem, a large amount of wear and wear bearing severe shaking speed and higher frequency of liquid pump damage. And the shaft should not be done too long, generally within 2 meters. The bearing of the pump is cooled and lubricated by the medium carried by the pump. If the medium is not refrigerated and lubricated by the pump, which will happen when the air pump is blocked with the imported material, it will burn or even burn the motor. And the repair and installation of the pump is very troublesome. In particular, there is no lifting tool that is difficult to complete when the corrosive medium is transported.
The advantages of stainless steel self-priming pump instead of subliquid pump are:
1, the vertical structure of the pump as a whole and the same parameters of the liquid pump compared to the weight greatly reduced at the same time less space. The shaft seal is not easy to leak because the shaft is installed in the vertical direction.
2, the self-priming pump cancels the long axis and also cancels the bearing problem, so that the maintenance of the same period is greatly extended and also reduces the vibration.
3. The parts that may be damaged and need to be repaired have brought great convenience to the maintenance of the ground. The pump inlet is only a hollow tube without bottom valve. If the inlet is blocked by the garbage, the hollow tube can be pulled out and the pump will need the whole pump to be cleaned.
4, the liquid pump to the pumping fluid to determine the depth at the time of purchase, if the liquid depth and the pump does not match the length of time you need to change to the pump, the pump provided with the hollow tubes of different lengths and different depths can be pumped without changing itself.
5, the operation of the air pump can still be maintained for a long time to help detect and take measures to prevent damage to motor in order to reduce the loss and safety caused by misoperation.
6, the liquid pump must be installed on the top of the liquid. This stainless steel self-priming pump can be installed on the top and can be installed in the side, and even can be used for vacuum hose suction pipe suction pipe can not reach the liquid mobility is very strong.
