Embodiment Construction
[0013] Such as figure 1 , 2 As shown, the water hammer protection device suitable for large-scale deep-buried long-distance water delivery pump stations according to the present invention includes a pressure water tank 1 installed on the outlet branch pipes of each water pump outside the pump room for confluence, and a pressure water tank 1 installed above the pressure water tank 1. The replenishment water tank 2. A plurality of intake and exhaust pipes 4 are installed on the top of the water supply tank 2, and each intake and exhaust pipe 4 extends vertically upwards from the central axis of the water supply tank 2 to the outside of the water supply tank 2, and the top of the intake and exhaust pipes 4 is installed. Valve 3; the lower part of the replenishment tank 2 is equipped with a plurality of replenishment resistance pipes 5 with a nominal diameter of DN720 connected with the pressure water tank 1, and each replenishment resistance pipe 5 extends vertically downward fr...

The invention discloses a water hammer protecting device suitable for a large deeply buried long-distance water delivering pump station. The water hammer protecting device suitable for the large deeply buried long-distance water delivering pump station comprises a pressure water tank, wherein the pressure water tank is arranged at a branch pipe junction position of an outlet of a water pump; a water replenishing tank is arranged above the pressure water tank; an air inlet and outlet tube with an air inlet and outlet valve is arranged on the top of the water replenishing tank; and a water replenishing resistance tube which communicates with the pressure water tank is arranged on the lower portion of the water replenishing tank. The water inlet and outlet tube and the water replenishing resistance tube are arranged in a staggered manner. compared with another water hammer protecting scheme, the scheme has obvious advantages in principle, safety and convenience of a long-distance water delivering system can be improved effectively, construction, running and maintaining costs for a water hammer protection measures are reduced, and engineering investment is saved.
Description
technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a water hammer protection device suitable for large deep-buried long-distance water delivery pump stations. Background technique [0002] With the development of my country's economy and society, the contradiction between supply and demand of water resources has become increasingly prominent. In order to ensure the water demand of various places, there are more and more water diversion projects for long-distance water transfer through large deep-buried pressurized pumping stations. For this type of pump station, it is usually required that the outlet pipe of the water pump is installed at an elevation about 3m lower than the water level of the inlet pool. However, since the design of the pump station is often limited by objective conditions such as terrain and geology, the actual installation elevation of the pump outlet pipeline is usually similar to or hi...
