Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to an integrated pump station with a prefabricated steel water inlet channel. Background Art

[0002] As a new type of stormwater and sewage treatment equipment, prefabricated pump stations differ from traditional concrete pump stations in terms of structure, installation, and operation and maintenance. They have been widely and successfully applied in related fields, including urban stormwater and sewage pipe network upgrading, municipal waterlogging drainage, underpass drainage, rural sewage disposal, urban river management, landscape water intake, and farmland irrigation. Composed of a cylinder system, pump units, pressure piping, electronic control systems, and other auxiliary components, prefabricated pump stations are complex flow systems.

[0003] In the prior art, such as the "integrated pump station" with patent application number CN201811166965.2, it includes an electrical cabinet control center and a hollow cylinder. The bottom of the cylinder is fixed on the base, and an upper head is placed on the top. An inlet pipe and an outlet pipe are provided on both sides respectively. The cylinder is an integrally injection-molded HDPE reinforced corrugated plastic wall tube, which consists of a cylindrical pipe body, a hollow corrugated reinforcement tube spirally wrapped around the outer wall of the pipe body, and reinforcing tendons therein; a submersible sewage pump and a submersible sewage pump autocoupling device are provided inside the cylinder, and the submersible sewage pump and the submersible sewage pump autocoupling device are installed on the base of the cylinder, and the submersible sewage pump is connected to the outlet pipe through a pipeline; the signal of the electrical cabinet control center is connected to the remote monitoring platform, and the remote monitoring platform collects data through GPRS or wired communication. This pump station can perform preliminary pretreatment of sewage, and has the advantages of being safe and reliable, unmanned, safe and convenient to maintain, energy-saving and environmentally friendly materials, low cost, and long service life.

[0004] In the existing technology, vortex-eliminating devices such as anti-vortex plates or water baffles are mostly used to optimize the flow state at the water pump suction port, but the water diversion method inside the prefabricated pump station is not optimized. When the liquid level in the prefabricated pump station drops too low, or the installation distance of multiple pumps is too close, it is still easy to have uneven medium flow and turbulence, which are not conducive to the operation of the water pump. If this continues for a long time, it will cause cavitation, mechanical vibration, reduced water pump performance, and damage to pump components. To solve the above problems, an integrated pump station with a prefabricated steel water inlet channel is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide an integrated pump station with a prefabricated steel water inlet channel to solve the problem that the existing technology proposed in the above background technology mostly uses vortex-eliminating devices such as anti-vortex plates or water baffles to optimize the flow state at the water pump suction port, and does not optimize the water diversion method inside the prefabricated pump station. When the liquid level in the prefabricated pump station drops too low, or the installation distance of multiple pumps is too close, it is still easy to have uneven medium flow, turbulence and other phenomena that are not conducive to the operation of the water pump. In the long run, it will cause cavitation, mechanical vibration, reduced water pump performance, and damage to pump components.

Powered by the water pump, it is pumped out through the water pump well to the pipeline connected to the outlet. The flap door can prevent the medium from flowing back. The steel water inlet channel can effectively regularize the turbulent flow state of the medium entering the cylinder. The size and shape of the steel water inlet channel can be adjusted to achieve the change of the flow rate of the conveying medium, stabilize the flow state at the water pump suction port, improve the stability of the submersible electric pump, and at the same time avoid two or more submersible electric pumps from grabbing water due to being too close to each other.

The electric control system facilitates the start and stop control of the equipment, thereby realizing automatic control. The electric control system can accurately control the start and stop, speed and other operating parameters of the water pump in the pump station. Through preset programs and algorithms, the water pump can be accurately operated according to factors such as water level changes and flow requirements, ensuring that the drainage or water supply function of the pump station is realized efficiently and accurately. The realization of automatic operation of the pump station is an important advantage of the electric control system, which can enable the pump station to operate normally without supervision. Through the data collected by various sensors, the electric control system can independently judge and execute the corresponding operations, greatly improving the operating efficiency, reducing the workload of manual operation and possible human errors. In addition, when it is detected that the water pump has an overload current, the voltage is too low or the motor temperature is too high, the electric control system will take timely measures, such as cutting off the power supply or sounding an alarm, to prevent equipment damage and extend the service life of the equipment.
