The way of taking water, that is, whether it is continuous or intermittent during the work period, whether there are special requirements for the water outlet pressure, water storage bucket, hose, etc .; 2. Water use during peak periods, that is, the duration of water intake peak and water consumption requirements, determine the machine specifications; 3.
