Purge kit

Types of Purge Kit

A purge kit contains tools and equipment designed to help professionals in many industries. It allows them to remove unwanted materials and substances from a specific system. It can be used to rid a system of contaminants, debris, and particulates. The purge kit can also eliminate excess air, moisture, and residual process materials from a system. There are different types of purge kits for various industries:

• Pneumatic Purge Kit

  A pneumatic purge kit is a portable air purge kit that uses compressed air to clean and purge equipment. The kit contains an air compressor, hoses, and various nozzles. The operator connects the kit to the equipment that needs purging. The compressed air flows through the nozzels and into the equipment. It dislodges any dirt, dust, and particulates from the surfaces and removes them. The pneumatic purge kit is widely used in industrial machinery and manufacturing equipment.

• Liquid Purge Kit

  Liquid purge kits are commonly used in chemical plants and laboratories. The kits use liquids, mostly solvents, to purge and clean equipment. The kit contains a pumping system, purge solvents, and a flushing system. Operators fill the purge kit with the required solvents. They may be water, ethanol, or any other compatible solvent. Then, they connect the flushing system to the equipment that needs purging and start the purging process. The operators flush the equipment using the liquid solvents. The solvents flow through the system, removing any contaminants. They could be particulates, residual chemicals, or any other unwanted material.

• Oil Purge Kit

  Oil purge kits are used to purge and clean oil and lubrication systems in heavy machinery and engines. The kits ensure the oil and lubrication systems are clean and contaminant-free. This guarantees optimal flow and performance. The oil purge kit contains a pumping mechanism and purging oil. Mechanics and technicians connect the oil purge kit to the oil system that needs purging. Then, they use the pumping mechanism to dislodge any contaminants from the oil systems. They may be particulates, dirt, or debris. The kit ensures the oil systems are clean.

• Gas Purge Kit

  Gas purge kits are used to remove unwanted gases from a system. They are very crucial during gas transfer operations. The kits ensure the desired gas composition is achieved before the transfer process begins. The gas purge kit contains gas cylinders, regulators, and purification gases. Technicians and operators connect the gas cylinders to the system that needs purging. Then, they use the gases from the cylinders to purge the system. This process helps to remove any residual gases and achieve the required gas composition.

Specification & Maintenance of Purge Kits

Here are some specifications one will find in a typical purge kit:

• Capacity: Purge kits come in different sizes and volumes, which are suitable for different sizes and scales of applications. The capacity of a purge kit is the maximum amount of liquid or gas it can hold.
• Purge Valve: The purge valve is the most important component of the purge kit as it controls the release of the gas or liquid during the purging process. The purge valve has different sizes, pressure ratings, and materials, which should be compatible with other components of the purge kit.
• Purge Pressure: The pressure used during the purging process is a key specification that must be considered. Depending on the application, purge pressure can be low or high, and it is important to ensure that the pressure is constant throughout the process.
• Flow Rate: Purge kits have different flow rates, which affect the efficiency and speed of the purging process. A purge kit with a higher flow rate is more efficient and reduces the time taken to purge a system or vessel.
• Purge Time: The time taken to complete the purging process is an important specification in a purge kit. Depending on the application, the purge time can be short or long.
• Material: Purge kits are made with different materials, such as stainless steel, brass, and carbon steel. Each material has its advantages and disadvantages, such as corrosion resistance, durability, and compatibility with other components.

Here are some maintenance tips for purge kits:

• Regular inspection: Carry out regular inspections to check for leaks, damage, or wear on the components of the purge kit.
• Cleanliness: Ensure that the purge kit is clean and free from debris, dirt, or contaminants that may affect its performance.
• Lubrication: Ensure that all moving parts of the purge kit are properly lubricated to reduce wear and tear and prevent damage.
• Replace worn components: Replace any worn-out or damaged components in the purge kit to ensure its proper functioning.
• Follow manufacturer's instructions: Carry out all maintenance procedures as instructed by the manufacturer.

How to choose purge kits

When buying a purge kit for resale, it is important to consider the target market. Are customers likely to purchase a standard purge kit or a more advanced programmable kit? Standard kits are affordable, but they might not have all the features that customers are looking for. Go for kits with multiple functions, such as the purge and fill kit, because they offer more value to customers.

Check the material construction of the purge kit. Nylon and copper are some of the common materials used to make purge kits. Kits made of nylon are affordable, but they are not very durable. Copper kits are durable, but they are heavier. It also takes a longer time to cool the purge kit when using copper. A brass purge kit is a better option because it is more durable than nylon and offers quick cooling compared to copper.

The size of the purge kit is another factor that affects the choice of purge kits. There are small and large kits. Small kits are portable, which makes them easy to carry around and perfect for on-site services. Large kits have more tools and are suitable for heavy-duty work. Some manufacturers give customers the option of choosing between small and large kits. This is a great way of meeting customer needs.

Look for purge kits that have been manufactured to high standards. The quality of the tools in the kit should be superior so that they can serve the customers for a long time. It might be hard to determine the quality of the tools, but reading reviews and going through the supplier's product samples can give some insights. Also, consider the warranty period offered by the supplier. A long warranty period is a show of confidence in the quality of the products.

How to DIY and replace Purge kit

Before attempting to replace a purge valve solenoid, it is important to have the right tools on hand. Mechanics and car owners will need a 10mm socket ratchet extension, a flathead screwdriver, and a new purge valve as they prepare to fix a vehicle's emissions system.

With the right tools, follow these steps:

• Disconnect the battery: It is advisable to disconnect the battery before doing any work in the engine bay. This will help avoid any electrical shorts and error codes from being triggered.
• Locate the purge valve: The purge valve is generally located near the back of the engine bay close to the firewall. It will have a couple of 10mm bolts holding it down. The purge valve will also have a few hoses connected to it. One hose comes from the gas tank and is routed to the evap pressure sensor. The other hose goes to the intake manifold.
• Remove the hoses: Use a flathead screwdriver to loosen the clamps holding the hoses to the purge valve. It may also be necessary to use the screwdriver to pry the hoses off the valve.
• Unscrew the purge valve: Use a 10mm socket to remove the bolts holding the purge valve. Once the valve is loose, pull it out of its mounting location. Be careful not to drop the bolts into the engine bay, as they may be hard to retrieve.
• Replace the valve: Take the new purge valve and install it into the mounting location. Tighten the bolts down with a 10mm socket. Do not over-tighten the bolts, as this may cause the plastic purge valve to break.
• Reconnect the hoses: Reconnect the two hoses to the purge valve. Make sure the clamps are tight so no air can get into the gas tank and throw off the evap pressure sensor readings.
• Connect the car battery: Reconnect the car battery and make sure the connections are clean.

After replacing the purge valve, it may take a few days of driving for the car's computer to fully complete the purge valve test. If the check engine light is still on, use an OBD2 scanner to read the codes and clear them. The emissions system should pass the test after a successful valve replacement.
