Annotation. The article discusses the advantages and disadvantages of hydraulic shock in water 
supply networks. Experiments have been carried out on hydraulic pump based on hydraulic 
forging. The hydraulic shock was calculated by controlling the flow of water using a calculation 
method recommended by L.F. Moshnin. In addition, the causes of hydraulic shock in water 
supply systems have been identified and simple and reliable methods have been proposed to 
reduce the effects of hydraulic shock. 
Key words: Hydraulic shock, pump aggregate, gate valve, valve. 
Introduction. Hydraulic lifting devices are named differently in different sources, such as water 
lifts, hydraulic pumps, and hydraulic pumps. According to scientists working in the field of 
hydraulic scanners, their history goes back a long way. 
In 1772, the English engineer J. Whitehurst was the first to create a hand-operated device 
resembling a hydraulic crane called the Whitehurst Device[1]. The first prototype of an 
automatically controlled hydraulic device was patented in 1797 by a British patent in 1797 for a 
joint invention by French scientists J. Mongolier and F. Frgand. The U.S. patent was granted in 
1809 to researchers J. Serneau and S. S. Hallett. In 1839, Strawbridge, an American 
businessman, began industrial production of hydraulic presses. In Russia, Professor SD 
Chistopolsky described the theoretical methods of calculating hydraulic shock absorbers based on 
N.Yu. Zhukovsky's theory of hydraulic shock in his 1930 book "Hydraulic shock"[2], [3]. 
The advantage of hydraulic ram devices is that, unlike pump units, no electric motor or 
muscle power is required for their operation. But the efficiency of such devices does not exceed 
0.2-0.5. Therefore, any research to improve the efficiency of their use has become one of the most 
pressing issues in the development of engineering devices that lift water upwards.
The principle of operation of the experimental device. The principle of operation of a hydraulic 
ram based on a hydraulic shock event was studied using the device shown in Figure 1.
