What are the advantages of submersible sewage pumps? Compared with the centrifugal pump, the submersible sewage pump has fewer blades and wider flow channel, which is more convenient for conveying sewage with fiber or other suspended impurities. So what are its advantages? The following is the introduction of its advantages. Advantage 1 Compact structure and small footprint. The vertical sewage pump can be directly installed in the sewage tank because it works under the water, without the need to build a special pump room for the installation of the pump and machine, which can save a lot of land and infrastructure costs. Advantage 2 Easy to install and maintain. Small vertical sewage pumps can be installed freely, while large vertical sewage pumps are usually equipped with automatic coupling devices for automatic installation, making installation and maintenance quite convenient. Advantage 3 Long continuous operation time. The vertical sewage pump has a short shaft and light rotating parts because the pump and motor are coaxial, so the bearing load (radial) is relatively small, and the service life is much longer than the general pump. Advantage 4 There is no cavitation damage and water injection problems. Especially the latter point brings great convenience to the operators. Advantage 5 Vibration noise is small, motor temperature rise is low, no pollution to the environment.

When purchasing a water pump, head is an important consideration. Head refers to the vertical height to which the pump can lift water. However, does this mean that a higher head is always better? To some extent, a higher head does have its advantages. It ensures that water can be delivered to a higher location or overcome greater resistance, which is crucial in certain applications. For example, in a water supply system that needs to deliver water to high-rise buildings, a higher head can meet the water needs of users on higher floors. However, simply pursuing a higher head isn't always a wise choice. First, high-head pumps are typically more expensive, which increases the purchase cost. If your actual needs don't require such a high head, purchasing a high-head pump may result in unnecessary waste of money. Second, high-head pumps often require more power to operate, which means higher energy consumption. In the long run, this can result in higher electricity bills and increased operating costs. Furthermore, high-head pumps can have some disadvantages in some situations. For example, in some applications where water velocity and pressure requirements are low, excessive head may cause excessive water turbulence, impacting and damaging pipes and equipment. Therefore, when purchasing a water pump, we shouldn't simply assume that higher head is better. We need to comprehensively consider actual usage needs, cost, and other factors. When determining head, we should accurately calculate and evaluate the specific application scenario, such as water supply height and pipe resistance. Other pump parameters should also be considered, such as flow rate, power, and efficiency. These parameters are interrelated and require a comprehensive balance when selecting a pump. In short, head is an important consideration when purchasing a water pump, but it's not the only one. We should make a reasonable choice based on our actual situation to ensure we purchase a pump that meets our needs and offers the best value for money. Don't blindly pursue high head; instead, consider a comprehensive approach based on the specific situation to achieve optimal performance and economic benefits.
Flange interface leakage Cause: This is typically caused by excessive strain on the fastening screws. Solution: Tighten the screws diagonally, not all at once. Ideally, the gasket between the two flanges should be the same size as the flanges. The motor is running but no water is being pumped out. Check the motor's direction of rotation Cause: The motor may be running in the wrong direction, or there may be air leaks at the inlet. Solution: Check the motor's direction of rotation and check for air leaks at the inlet. Mechanical seal leakage The mechanical seal is burned due to dry pumping without water Possible cause for new pumps: Dry running without water may damage the shaft seal. For older pumps, there are several possible causes: 1. Wear on the dynamic and static seal surfaces Cause 1: Overtightening. Observe the dynamic and static seal surfaces. If there is severe burning, blackening, or deep marks, or if the sealing rubber has hardened and lost its elasticity, this is due to overtightening. Cause 2: Too loose installation. Observe the surfaces of the dynamic and static seal rings. A thin layer of scale can be wiped off, and the surfaces are largely unworn. This is caused by a loss of spring elasticity, improper assembly, or axial movement of the motor. Cause 3: Poor water quality containing particles. Poor water quality, containing small particles and a high hydrochloric acid content in the medium, can cause abrasive wear on the seal surfaces or strain, creating grooves and annular grooves. Cause 4: Dry wear damage caused by water shortage. This phenomenon is often seen in bottom-valve installations with negative inlet pressure, air in the water inlet pipe, and air in the pump cavity. After the pump is started, the friction of the seal at high speed generates high temperatures, preventing cooling. Check the seal to see if the spring tension is normal, the friction surface is charred and blackened, and the rubber is hardened and cracked. Cause 5: Cavitation. Cavitation primarily occurs in hot water pumps. Because the medium is hot water, the high water temperature generates steam. Steam in the pipes enters the high areas of the pump chamber, where it cannot be expelled. This causes water shortages, dry wear of the mechanical seal, and cavitation. An automatic exhaust valve must be installed and the mechanical seal replaced. Cause 6: Assembly issues. The pump cover may not be installed level, causing the shaft and cover to be misaligned, resulting in misalignment of the moving and static surfaces. Short operation can lead to wear on one side and water leakage. It's also possible that the rubber components or surfaces of the moving and static rings may be damaged during installation. 2. Mechanical sealant failure Causes of mechanical sealant failure: Aging and deformation of rubber components, primarily in hot water pumps. Symptoms of mechanical sealant failure include excessively high water temperatures, which dissolve the rubber. Visually, the rubber surface appears loose and rough, losing its elasticity, leading to failure. 3. Causes of failure in the static ring chamber of the pump cover The primary cause is large dimensional errors in the machining of the inner bore of the static ring chamber, resulting in a rough surface. Symptoms include water spraying from the axial direction, a gap between the stationary ring and the inner bore, or a rough inner bore, causing the stationary ring to rotate with it and rubber wear. 4. Poor machining precision, undersized, rough, or rusty motor journals The motor journal (where the rotating ring rests) may be undersized, or the pump may be corroded by corrosive media, or due to prolonged downtime, with water acting as the medium. The electrode potential difference between the steel shaft and the cast impeller and pump cover creates a galvanic reaction, leading to journal corrosion. Symptoms include spotty corrosion on the surface.
