A vertical sewage pump is a type of vertical drainage equipment used to convey wastewater and other liquids that contain solid particles, fibers, and other impurities.
I. Features of Vertical Sewage Pumps
Vertical sewage pumps are characterized by anti-clogging, non-blocking, and energy-efficient performance. They can pass large solid particles and long fibers, making them suitable for conveying sewage and corrosive media.
II. Huaquan Power is a professional vertical sewage pump manufacturer in China.
Huaquan Power Company was established in 2010. Its business spans multiple fields, including power generation equipment, new energy storage equipment, high and low voltage complete sets of equipment, and electric power engineering. It has created three major brands: "HQ-POWER," "HUAQUAN," and "Huaquan." Currently, the company has developed into a strong global brand in the power industry, with cumulative global sales exceeding 1 million units.
III. Advantages of Vertical Sewage Pumps
1. Vertical sewage pumps are highly efficient and energy-saving in terms of performance. They are reasonably designed and paired with high-efficiency motors, resulting in significant energy savings and relatively low operating noise. Their unique impeller structure gives them anti-clogging and anti-winding capabilities.
2. In terms of structure and installation, vertical sewage pumps have a compact overall structure and small size, requiring no dedicated pump room. They can operate submerged in water, greatly reducing construction costs.
3. Vertical sewage pumps operate stably and reliably. The rotor components, balanced through calibration, and the reasonable bearing arrangement effectively balance radial and axial forces, ensuring long-term stable operation with minimal vibration.
IV. Precautions for the use of vertical sewage pumps
1. Vertical sewage pump installation and inspection before starting
During installation, the vertical sewage pump body should be placed horizontally and reliably fixed, and the suction and discharge pipelines should be independently supported and should not be directly load-bearing by the pump body. Before starting, it is necessary to check whether the power supply voltage is consistent with the requirements of the motor nameplate, and ensure that the insulation resistance of the motor winding to the ground is not lower than the specified value (such as 50 megaohms). At the same time, the vertical sewage pump shaft needs to be manually discussed to confirm that the rotation is flexible and there is no jamming, and check whether there is any blockage or leakage in the pipeline. For three-phase electric pumps, jogging should be checked whether the motor steering is correct, and any two-phase power cord should be replaced if it is reversed.
2. Operation and monitoring
When the vertical sewage pump starts, the outlet valve should be closed first, and then opened slowly after the motor speed is stable to reduce the starting current. During operation, it is necessary to closely monitor whether the current, voltage, flow rate and pressure are normal, and the bearing temperature should not exceed 35°C of ambient temperature, and the maximum should not exceed 75-80°C. At the same time, pay attention to whether there is any abnormal sound or vibration in the pump body of the vertical sewage pump, and if there is, stop the machine immediately for inspection. It is strictly forbidden to overflow or exceed the rated head range to avoid overloading the motor.
3. Shutdown and special environmental treatment of vertical sewage pumps
When the machine is stopped, the outlet valve should be closed first, and then the power supply should be cut off to impact the vertical sewage pump with waterproof backflow. After stopping the pump in the cold season, it is necessary to unscrew the water screw plug to drain the accumulated water in the pump to prevent freezing and cracking. If it is stopped for a long time, the water in the vertical sewage pump should be dried, and grease should be applied to the rotating part to prevent rust. In addition, the vertical sewage pump should not be started frequently, and the interval between the two starts should be about 5 minutes to avoid the motor starting with load due to the backflow of water in the pipe.
V. Q&A on Vertical Sewage Pumps
1. What key parameters need to be monitored during the operation of a vertical sewage pump?
It is necessary to closely monitor whether the current and voltage are normal, observe the flow and pressure, and pay attention to any abnormal vibrations or noises from the pump body. The bearing temperature generally must not exceed 75°C.
2. What are the main points of daily maintenance for vertical sewage pumps?
Regularly check and tighten connections, clean debris from the pump and pipelines, and replace bearing lubricating oil or mechanical oil periodically as required.
3. What are the common installation methods for vertical sewage pumps?
There are mainly two types: a fixed automatic coupling installation system and a mobile free installation system. The former is convenient for installation and maintenance.
VI. Application Areas of Vertical Sewage Pumps
1. Industrial Sector: Vertical sewage pumps are used for wastewater discharge in industries such as chemical, petroleum, pharmaceutical, mining, paper-making, cement, and power plants, as well as for transporting chemical liquids in processes like etching lines and washing towers.
2. Municipal and Construction Sector: Vertical sewage pumps are key equipment in urban sewage treatment plant drainage systems, civil defense projects, subways, and basement drainage stations. They are also used for sewage discharge in hospitals, hotels, high-rise buildings, and residential areas.
3. As Water Supply Equipment in Water Treatment Plants: Vertical sewage pumps are also used for discharging thin mud in construction and municipal engineering projects.
4. Agriculture and Other Areas: Vertical sewage pumps are suitable for rural biogas digesters, field irrigation, livestock farm sewage discharge, and can even replace manual labor for suctioning river sludge.
Vertical sewage pumps have the advantages of high efficiency, energy saving, compact structure, and easy maintenance, and they are widely used. Users should select the appropriate vertical sewage pump according to specific operational requirements.
