The advantage of the stainless steel self-priming pump in the low-level conveying of corrosive liquids Generally, when the liquid is delivered, the centrifugal pump needs to pump the pump to discharge water when the liquid level is lower. For this purpose, a bottom valve is required at the pump inlet. When the long-bottom valve is corroded or stuck, it is inconvenient to exchange or repair it.
The advantage of stainless steel "target=_blank> stainless steel self-priming pump in the low-level conveying of corrosive liquids. Generally, when the liquid is delivered, the centrifugal pump needs to pump the water to discharge the water when the liquid level is lower. To do this, install the bottom valve at the pump inlet. When the long-bottom valve is corroded or stuck, it is inconvenient to exchange or repair. The submersible pump is generally used to transport clean water and river water, and it is prone to motor corrosion when used for transporting corrosive liquids such as acid and alkali. The leakage phenomenon is very unsafe. It is very inconvenient to pull the pump when it is blocked by the garbage, so it is rarely used in practical applications. So people have created a submerged pump for low-level transportation, and the submerged pump solves it. The problem of low position conveying. However, due to the long axis and the unbalanced radial force of the impeller, the whole shaft is a cantilever structure, so the rotation of the impeller end causes a large deflection axis and the greater the deflection. The repair and installation of the lower pump is very cumbersome, especially when transporting corrosive media without lifting tools. The submerged pump solves the problem of low transport, but it also brings a lot of The trouble in use. Shanghai Yiling Pump Co., Ltd. introduced stainless steel "target=_blank> stainless steel self-priming pump produced by foreign advanced technology, which is specially designed for low-level liquid transportation for the above disadvantages of the submerged pump. It can replace the long-axis submerged pump on the ground with a self-priming height of up to 8 meters. It can be used as a bottom pump or a sweeping pump on board.
First, the advantages of stainless steel "target=_blank> stainless steel self-priming pump instead of submerged pump
1. Compared with the submerged pump with the same parameters, the pump has a vertical structure and the weight is greatly reduced while occupying less space. Since the shaft is installed in the vertical direction, the shaft seal is not easily leaked.
2. The self-priming pump cancels the long axis and also cancels the bearing problem, which greatly prolongs the maintenance and reduces the vibration.
3. The parts that may be damaged and need to be repaired are on the ground, which brings great convenience to the maintenance. The inlet of the pump is only a hollow tube that does not require a bottom valve. If the inlet is blocked by garbage, the hollow tube can be cleaned by pulling it out, while the submerged pump requires the entire pump to be lifted.
4. The submerged pump needs to determine the depth of pumping when purchasing. If the depth of the liquid does not match the length of the pump shaft, the pump needs to be replaced. The vertical self-priming pump can pump different depths as long as it is equipped with hollow tubes of different lengths. Need to change itself.
5, the empty pump operation can still be maintained for a long time, in order to facilitate detection and take measures to prevent damage to the motor, reduce the loss caused by misuse and safety.
6. The submerged pump must be installed directly above the liquid. The self-priming pump can be installed either on the top or on the side, and even the vacuum-resistant hose can be used to suck the liquid that cannot be reached by the straight pipe, and the mobility is very strong.
Second, save investment
Due to the frequent maintenance of the submerged pump, generally two pumps are required for one tank (tank), one pump is used for maintenance and backup, the investment is huge, and the maintenance is large. The self-priming pump can realize multi-cell (slot) string and parallel sharing of one pump to save investment. The self-priming pump can be used for intermittent operation of gas and liquid, and is not afraid of pumping out. It can save some intermediate equipment in the process flow, greatly simplifying the process flow and saving you money.
Third, the principle and application of stainless steel "target=_blank> stainless steel self-priming pump
The self-priming pump principle uses a unique patented impeller and separation disc to force the gas-liquid separation to complete the inhalation process. Its shape, size, weight and efficiency are similar to those of pipeline pumps. Vertical self-priming pumps do not require auxiliary equipment such as bottom valves, vacuum valves, and gas separators. The normal production start-up does not require a strong self-priming ability, and can replace the currently widely used submerged pump (low-level liquid transfer pump), and can be used as an auxiliary device such as a separator. It does not need to be filled with normal liquid to have a strong self-priming ability. It can replace the widely used submerged pump (low level liquid transfer pump) for circulating pump, tank truck, self-priming pump, motorized pump, etc. .
