A surge tank (or surge drum) is a standpipe or storage reservoir at the downstream end of a closed aqueduct or feeder or a dam or barrage pipe to absorb sudden rises of pressure, as well as to quickly provide extra water during a brief drop in pressure.

In mining technology, ore pulp pumps use a relatively small surge tank to maintain a steady loading on the pump.

For hydroelectric power uses, a surge tank is an additional storage space or reservoir fitted between the main storage reservoir and the power house (as close to the power house as possible). Surge tanks are usually provided in high or medium-head plants when there is a considerable distance between the water source and the power unit, necessitating a long penstock. The main functions of the surge tank are: 1. When the load decreases, the water moves backwards and gets stored in it. 2. When the load increases, additional supply of water will be provided by surge tank.

In short, the surge tank mitigates pressure variations due to rapid changes in velocity of water.

Operation

Consider a pipe containing a flowing fluid. When a valve is either fully or partially closed at some point downstream, the fluid will continue to flow at the original velocity. In order to counteract the momentum of the fluid the pressure will rise significantly (pressure surge) just upstream of the control valve and may result in damage to the pipe system. If a surge chamber is connected to the pipeline just upstream of the valve, on valve closure the fluid instead of being stopped suddenly by the valve will flow upwards into the chamber hence reducing the surge pressures experienced in the pipeline.

Upon closure of the valve, the fluid continues to flow, passing into the surge tank causing the water level in the tank to rise. The level in the tank will continue to rise until the additional head due to the height of fluid in the tank balances the surge pressure in the pipeline.[1] At this point the flow in the tank and pipeline will reverse causing the level in the tank to drop. This oscillation in tank height and flow will continue for some time but its magnitude will dissipate due to the effects of friction

surge tank缓冲罐我也不知道是干嘛的求解

surge tank泥浆混合的地方。至于重晶石，膨润土，盐水、基油都是调配泥浆的原料

surge tank 叫缓冲罐，有cement surge tank和bulk mud surge tank,一般cement surge tank 有一个，bulk mud surge tank有两个，他们是将p- tank(灰罐）里面送过来的散灰通过surge tank下面的hopper打到泥浆池或者水泥池进行混合！

缓冲罐，也是平台的一个系统
