Based on drainage requirements, scale, topographical and geological conditions, pipe burial depth, pump type, and construction conditions, a comprehensive selection is made after technical and economic comparisons. Common types of sewage pump stations include:
Jointly constructed, self-priming sewage pump stations are designed with the collection pool and machinery room located within the same building, separated by partitions. The pumps are self-priming, offering convenient operation. The pump stations come in various shapes, including circular, rectangular, and bottom-circular-top-rectangular. The circular pump station has favorable structural stress conditions, making the sinking well method of construction suitable, with lower costs. However, due to the semi-circular machinery room, the arrangement of the unit and equipment is challenging, making it suitable for medium and small-scale pump stations. When dealing with large amounts of sewage and numerous pumps, rectangular pump stations are preferable. These stations have a well-arranged machinery room, with the length determined by the pump model and quantity. For large sewage volumes, numerous pumps, and poor geological and hydrological conditions requiring the sinking well method, bottom-circular-top-rectangular pump stations can be used. Jointly constructed pump stations utilize horizontal or vertical pumps. When horizontal pumps are used, the motor is placed below the shed, making it prone to moisture and inconvenient for operators to climb stairs. Vertical pump systems can avoid these issues but require the unit's axis to be kept vertical during installation to prevent vibration during operation, which can lead to wear and reduce the lifespan of the machinery.
2. Separate Construction Pump Stations. When the soil bearing capacity is poor and the groundwater level is high, separate construction wastewater pump stations are commonly used to save on engineering investment and facilitate construction. These pump stations are constructed with the collection pond and machinery room being built separately. The water pump's suction method is non-self-priming. The floor level of the machinery room can be higher than the water level of the collection pond, but must be lower than the actual allowable suction vacuum height of the pump. The advantages of separate construction pump stations include simple construction, ease of construction, and low investment. The disadvantages are that before the pump can start, air in the suction pipe must be removed using a vacuum system, making the operation cumbersome.
