Hey there! As a supplier of ordinary pressure gauges, I often get asked about pressure shock absorption. So, let's dive right in and talk about what it is and why it matters for an ordinary pressure gauge.
What is Pressure Shock?
First off, we need to understand what pressure shock is. Pressure shock, also known as water hammer (even though it can happen with other fluids too), occurs when there's a sudden change in the flow velocity of a fluid in a pipeline. This can be caused by things like quickly closing a valve, a pump starting or stopping abruptly, or a sudden change in the system's operating conditions.
When pressure shock happens, it creates a high - intensity pressure wave that travels through the fluid. This wave can reach pressures much higher than the normal operating pressure of the system. For example, in a water system, a sudden valve closure can cause the pressure to spike to several times the normal pressure.
Why is Pressure Shock a Problem for Pressure Gauges?
Ordinary pressure gauges are designed to measure the normal, steady - state pressure of a system. When a pressure shock occurs, the sudden increase in pressure can damage the delicate internal components of the gauge. The Bourdon tube, which is a common sensing element in pressure gauges, can get over - stressed and deformed. This deformation can lead to inaccurate readings or even complete failure of the gauge.
Also, the mechanical linkages and gears inside the gauge can be subjected to excessive forces during a pressure shock. These forces can cause the gears to strip, the linkages to break, or the pointer to get misaligned. As a result, the gauge becomes unreliable, and you can't trust the pressure readings it provides.
Pressure Shock Absorption in Ordinary Pressure Gauges
Pressure shock absorption is the process of reducing the impact of pressure shocks on the pressure gauge. There are several ways to achieve this, and different ordinary pressure gauges may use one or more of these methods.
1. Snubbers
One of the most common ways to absorb pressure shock is by using snubbers. A snubber is a small device that is installed between the pressure source and the pressure gauge. It works by restricting the flow of fluid into the gauge. When a pressure shock occurs, the snubber slows down the rate at which the high - pressure wave reaches the gauge. This gives the gauge more time to adjust to the pressure change and reduces the peak pressure that the gauge has to withstand.
There are different types of snubbers, such as orifice snubbers and needle valve snubbers. Orifice snubbers have a small hole (orifice) that restricts the flow, while needle valve snubbers allow you to adjust the flow restriction by turning a needle - shaped valve.
2. Liquid - Filled Gauges
Another effective method of pressure shock absorption is using liquid - filled gauges. These gauges are filled with a liquid, usually glycerin or silicone oil. The liquid acts as a damping medium. When a pressure shock occurs, the liquid absorbs some of the energy from the pressure wave and dissipates it as heat. This reduces the impact of the shock on the internal components of the gauge.
The liquid also provides lubrication to the moving parts inside the gauge, which helps to reduce wear and tear. Additionally, it protects the internal components from corrosion and environmental damage.
3. Flexible Connections
Using flexible connections between the pressure source and the gauge can also help with pressure shock absorption. Flexible hoses or bellows can absorb some of the vibrations and pressure fluctuations caused by pressure shocks. They act as a buffer, isolating the gauge from the full force of the shock.
Benefits of Pressure Shock Absorption
The main benefit of pressure shock absorption in ordinary pressure gauges is increased reliability. By protecting the gauge from the damaging effects of pressure shocks, the gauge can provide accurate and consistent pressure readings over a longer period of time. This is crucial in many industrial applications where precise pressure measurement is essential for safe and efficient operation.
It also reduces the need for frequent gauge replacements. Since the gauge is less likely to be damaged by pressure shocks, you don't have to spend as much money on buying new gauges or on maintenance and repair. This can result in significant cost savings for your business.
