Vertical self-priming pump low corrosive liquid delivery advantages

June 07, 2024

Advantages of Vertical Self- Priming Pump in Low Corrosive Liquid Delivery Generally, when the liquid level is lower than the centrifugal pump, the pump needs to be filled to discharge water. To do this, install a foot valve at the pump inlet. Over time, the end of the valve is corroded or stuck, you need to be replaced or repaired, it is very inconvenient to use. Submersible pumps are generally used to transport clean water and river water, but are prone to motor corrosion and leakage when used for transporting acids and other corrosive liquids. It is unsafe. Pump is blocked by garbage pump must be pulled to clean up, very inconvenient, so rarely used in practical applications. So people created a liquid pump for low delivery, liquid pump to solve the problem of low delivery. However, due to the use of the long axis, combined with the unbalanced radial impeller force, the entire shaft and cantilever structure, so the rotation caused a lot of deflection in the impeller. The longer the axis, the greater the deflection. In order to solve this problem, a bearing is mounted on the shaft. However, because the whole shaft is a flexible shaft, the bearing is subjected to unilateral wear and tear, large wear, bearing sway violently, wear faster, so the submerged pump higher damage frequency. And the shaft should not be done too long, generally within 2 meters. Underwater pump bearings are transported by the pump medium cooling and lubrication. If, once the pumped medium is not refrigerated and lubricated to the bearing (which happens when the pump is empty and when the inlet is clogged with debris), a bush or even a motor burn out. The liquid pump repair and installation is very troublesome. Especially in the delivery of corrosive media, it is difficult to accomplish without lifting tools.
Submerged pump to solve the problem of low delivery, but it also brings a lot of trouble in use. Shanghai Kai on the Pump Co., Ltd. to introduce advanced foreign technology patent vertical self-priming pump, is designed for the above shortcomings of liquid pumps, specifically designed for low-level liquid transport. It replaces the long-axis submerged pump on the ground, self-priming up to 8 meters in height and can be used as a bottom-bilge pump and a sweep-out pump on board.
A: The advantages of alternative liquid pumps:
1, the pump as a whole vertical structure, with the same parameters of the submerged pump, the weight greatly reduced, while occupying less. Due to the vertical shaft installation, shaft seal is not easy to leak.
2, self-priming pump canceled the long axis, but also canceled the bearing problems, so that maintenance over the same period greatly extended, but also reduce the vibration.
3, the parts that may be damaged and need to be repaired are on the ground, which brings great convenience to maintenance. Pump imports is only a hollow tube, do not need the end of the valve. If the entrance is blocked by garbage, the hollow tube can be pulled out to clean, and submerged pump you need to lift the entire pump to clean up.
4, the liquid pump to be determined at the time of purchase pumping depth, if the liquid depth does not match the length of the pump shaft, you need to change the pump, and vertical self-priming pump with different lengths of hollow tube, you can pump different depth and No need to change itself.
5, the air pump operation can still be maintained for a long period of time, in order to facilitate the detection and take measures to prevent damage to the motor, reducing misuse caused by the loss, good safety.
6, liquid pump must be installed directly above the liquid. The self-priming pump can be installed in the top, can also be installed next to, or even vacuum hose can be used to draw straight tube can not reach the liquid, mobility is very strong.
Second: save investment:
Due to the frequent maintenance of submerged pumps, the general pool (tank) need to set up two pumps, a pump for maintenance spare, huge investment, large amount of maintenance. The self-priming pump can achieve multi-tank (tank) string, a pump in parallel, saving investment. Self-priming pump can be used for gas, liquid intermittent operation, not afraid of taking the time to save some intermediate processes in the process, such as high slot or low slot, greatly simplifying the process for you really save money.
Three: Kai vertical self-priming centrifugal pump principle and application:
Self-priming pump principle Use a unique patented impeller and separation plate to force the gas-liquid separation and complete the inspiratory process. Its shape, size, weight, efficiency and pipeline pump similar. Vertical self-priming pump does not require the end valve, vacuum valve, gas separator and other auxiliary equipment. Normal production starts without need for irrigation, has a strong self-priming capability, can replace the currently widely used submerged pump (low liquid pump), can be used as a separator and other auxiliary equipment. Normal production starts without the need for irrigation, has a strong self-priming capability, can replace the currently widely used submerged pump (low liquid pump), can be used for circulating pump, tank truck pump, self-priming pipeline pump, motor pump Other uses.
