Energy distribution of portable high pressure cleaning machine and improvement of cleaning efficiency

Author: admin Release time: 10:04, July 14, 2018 Number of visits:

In recent years, the development of portable high-pressure cleaning machine is relatively rapid, has been widely used in various industries, such as casting, machinery, oil field, household and other industries.
 
Portable High pressure cleaning machine The working principle is to use the high-pressure pump to change the mechanical energy of the power source into the pressure energy, and also has relatively high pressure water. Through the small hole of the high-pressure nozzle, the pressure energy can be transformed into kinetic energy, so as to form a relatively small water jet. Using the strong impact force of high-pressure water jet and the object being cleaned, the dirt is stripped from the object to achieve the purpose of cleaning,
 
So how can we more effectively use the energy of high pressure water jet to improve the cleaning efficiency to complete a new topic? Together with the portable high-pressure cleaning machine manufacturers to understand it!
 
According to Bernoulli equation, the total energy of portable high-pressure cleaning machine is composed of potential energy, static pressure energy and dynamic pressure energy. The potential energy can be ignored because it is too small. At the nozzle outlet, the static pressure energy is completely converted into dynamic pressure energy due to the infinite expansion of the flow channel. In this case, the total energy of the injection system of the portable high-pressure cleaning machine can be expressed by the following formula:
 
Formula for calculating total energy of injection system of portable high pressure cleaning machine (1)
 
In formula (1): total energy of portable high-pressure cleaning machine - total energy of injection system of portable high-pressure cleaning machine, m;
 
Energy loss of upper section of portable high pressure cleaning locomotive - energy loss of upper section of locomotive, m;
 
Energy loss of high pressure hose section of portable high pressure cleaning machine energy loss of high pressure hose, m;
 
Energy loss of nozzle section of portable high-pressure cleaning machine - nozzle energy loss, m;
 
Jet kinetic energy at nozzle outlet of portable high-pressure cleaning machine - jet kinetic energy at nozzle outlet, M.
 
In formula (1), instead of the calculation formula of the energy loss of the nozzle section of the portable high-pressure cleaning machine and the calculation formula of the jet kinetic energy at the nozzle outlet of the portable high-pressure cleaning machine, the formula (2) can be obtained
 
Formula for energy calculation of portable high pressure cleaning machine (2)
 
In formula (2), ζ is the energy loss coefficient of nozzle;
 
High pressure water jet nozzle outlet velocity - jet outlet velocity, M / S;
 
G-acceleration of gravity, M / S 2.
