Hydrostatic Pressure Testing Machine and Its Components
Hydrostatic pressure (HP) measurement is the scientific process used to evaluate how well the equipment is able to resist the force of water exerted on it. This testing process is often performed when equipment parts are new or when they are undergoing repair or maintenance. It is often required to determine whether an apparatus can work properly given its age and the current conditions it finds itself in.
Hydrostatic pressure measuring device is a very common testing process to check that certain equipment or devices do not possess manufacturing defects or leaks. The hydrostatic pressure measuring machine’s vessel to be tested normally is placed inside an airtight sealed chamber. Typically, the sealed chamber is filled with either water or incompressible fluids. A hose, usually fitted to the machine’s output port is attached to the other end of the hose. This test is often done when new equipment is being installed or when it is being repaired or maintained.
The hydraulic pressure testing machine’s output port is equipped with an output hose that supplies hydraulic fluid to the other end of the sealed chamber. The impeller is usually located on the outer side of the plastic pipe fittings assembly. The impeller performs a vane operation that forces the hydraulic fluid against the impeller blade. As the fluid moves towards the output, it forces the blade against the fluid thus measuring the amount of hydraulic pressure being produced.
Hydraulic pressure measuring equipment consists of various other parts which are used in the process. One of the other important parts of the hydrostatic pressure testing equipment is the Hydraulic isolation valves. These valves are intended for use only for specific pipe connections and are available in different sizes to suit the applications.
A specific pressure measuring device for hydrostatic pressure testing equipment is the pressure transducer. This is a special device which is used to measure the pressure of the hydraulic fluid. The transducers are usually made up of a column of mercury material and are suspended over the area that is to be measured. A flexible metallic tube or hose is fixed to the column of mercury material and extends out beyond the area to be measured.
An important component for the hydrostatic pressure testing machine is the computerised control system. This control system provides a user with a complete graphical user interface which enables easy configuration and execution of the machine operations. Different types of commands for different types of tests can be executed by using the appropriate keys. It also contains many parameters, which when reconfigured in the proper manner will enable the machine to return to the initial conditions after a test is completed successfully. Some other useful parameters in the computerised control system are the rate at which water flows through the pipes, the rate at which the pressure falls and the length of the pipes that are to be measured.
