A float switch in a lubrication system is a type of level sensor used to monitor the oil or lubricant levels in various industrial machines and equipment. It plays a crucial role in maintaining proper lubrication levels, which is essential for the smooth and efficient operation of machinery.

Here's how a float switch typically works in a lubrication system:

• Float: The float is a buoyant object that floats on the surface of the lubricant. It is usually made of a material with low density, such as plastic or foam.
• Switch mechanism: The float is connected to a switch mechanism. When the lubricant level is at an optimal or normal level, the float remains buoyant, keeping the switch in its default position.
• High level detection: If the lubricant level rises above the desired level, the float will also rise, triggering the switch to change its position. This position change activates an electrical signal indicating a high-level condition.

A pressure switch in a lubrication system is a device used to monitor and control the pressure of lubricating oil or fluid within the system. It is commonly employed in machinery, engines, and other equipment that require proper lubrication to operate effectively and prevent damage from friction.

The pressure switch typically consists of a sensing element, which can be a diaphragm or a piston, and electrical contacts. When the pressure of the lubrication system reaches a certain predetermined level, the sensing element responds by activating or deactivating the electrical contacts. This change in the status of the contacts can trigger various actions, such as turning on or off a lubrication pump, activating an alarm, or shutting down the equipment to prevent further operation without adequate lubrication.

A pressure gauge in a lubrication system is a device used to measure and display the pressure of the lubricating oil or fluid within the system. It provides real-time information about the pressure levels, allowing operators to monitor and maintain optimal operating conditions.

The pressure gauge consists of a pressure-sensitive element, usually a bourdon tube or a diaphragm, and a calibrated scale that indicates the pressure reading. As the lubrication system operates, the pressure of the oil or fluid exerts a force on the pressure-sensitive element, causing it to deform. This deformation is then translated into a pressure reading on the gauge's scale.

It's important to note that pressure gauges should be selected and installed based on the specific requirements of the lubrication system and the operating conditions. Factors such as pressure range, accuracy, durability, and compatibility with the fluid being measured should be considered.

An oil filler in a lubrication system is a component that allows for the convenient and controlled addition of lubricating oil or fluid into the system. It serves as a port or opening through which fresh oil can be added to replenish the system and maintain the proper oil level.

The oil filler typically consists of a cap or cover that secures the opening and prevents contaminants from entering the lubrication system. It may have a built-in vent or breather to equalize pressure inside the system during the filling process. Some oil fillers may also incorporate a filter or strainer to remove any particles or impurities present in the oil being added.

When the lubrication system requires additional oil, the oil filler cap is removed, and fresh oil is poured or pumped into the system through the opening.

A suction strainer, also known as a suction filter or intake strainer, is a component commonly used in lubrication systems to remove contaminants and debris from the incoming oil before it enters the system's pump or other components. It is typically positioned at the inlet of the pump or suction line to protect the system from potential damage caused by particulate matter in the lubricating oil.

The primary function of a suction strainer is to prevent solid particles, such as dirt, metal shavings, and other debris, from entering the lubrication system. These particles can cause wear, abrasion, and clogging of components, leading to reduced system efficiency and potential failure.

A suction strainer is typically constructed using a mesh screen or perforated metal filter element housed in a casing.

A relief valve in a lubrication system is a safety device designed to protect the system from overpressure. It is responsible for preventing excessive pressure build-up within the system by releasing or relieving the excess pressure when it exceeds a predetermined set point.

The relief valve consists of a valve mechanism, a spring, and an adjustable pressure setting. The valve is normally held closed by the force of the spring, keeping the lubrication system pressurized within a safe range. When the pressure within the system exceeds the set point, the force exerted by the excess pressure overcomes the spring tension, causing the relief valve to open and divert the excess fluid or oil flow.

Once the relief valve opens, the excess fluid is typically directed to a low-pressure area, a reservoir, or back to the oil sump, depending on the system's design.
