The two-color water level gauge is widely used for monitoring liquid levels in pressure vessels and industrial steam boilers. It provides a clear visual indication of the water level, making it an essential tool in boiler systems.
Common issues with two-color water level gauges include:
(1) Mismatched center distances between the steam and water valves of the gauge and the corresponding outlets on the drum.
(2) Incompatibility between the working pressure of the drum and the rated pressure of the water level gauge.
The two-color water level gauge was developed by enhancing the traditional glass water level gauge with a prism. This prism uses the principle of light transmission and reflection through different media to distinguish between water and steam. As a result, the water appears green, while steam appears red, creating a sharp contrast that makes the interface easily visible. This design ensures that the colors do not mix, even under normal operation. However, improper installation or usage can cause the device to malfunction.
To ensure proper performance, the following steps should be followed during installation:
(1) Inspect all parts of the gauge for blockages or leaks before installation.
(2) Confirm that the center distance between the steam and water valves of the gauge matches that of the drum’s steam and water outlets.
(3) Ensure that the rated pressure of the water level gauge matches the operating pressure of the boiler. For example, 1.6 MPa gauges are suitable for pressures below 1.3 MPa; 2.5 MPa models work best for 1.3–2.0 MPa; and 2.0 MPa gauges are ideal for 2.0–3.5 MPa.
(4) After unboxing, store the water level gauge separately to avoid damage.
(5) During installation, clean the components carefully, avoid striking them, and apply bolts evenly to prevent stress or cracks.

Tamping Rammer
Tamping rammer:it is made according to the principle of two-stroke internal combustion engine, and there are two pistons in the cylinder, the upper piston is the internal combustion piston, and the lower piston is the buffer piston. The lower part of the cylinder is equipped with a rammer that slopes the bottom surface, so that the vertical axis of the cylinder is skewed forward. The upper piston rod stretches out from the through hole in the middle of the cylinder top cover, and the lower piston rod stretches out from the lower end face of the cylinder, and is integrated with the rammer, and the cylinder and the rammer are tightened by a spring, and a handrail is provided to control the forward direction of the rammer. The fire rammer is under the action of the ignition and explosion force of the combustible mixture, therefore, it jumps off the ground in front of the top and under the action of its own weight, and falls to the ground to ram the soil, and the rammer jumps and falls, and the fuselage moves forward step by step. The rammer product has a wide range of uses, not only suitable for tamping and leveling with various sand, gravel and triple soil, but also suitable for tamping and leveling asphalt gravel, concrete and clay, especially suitable for the construction of buildings, ground, courtyards, roadbeds, bridge piles, trenches, fields, narrow sites and other environments.
