How to make vacuum pump?[2 details method]

Are you facing a problem with making a vacuum pump? Don’t worry!!! Many people face this problem. I think you don’t face this difficulty after reading this article.

Vacuum pumps pull out the air inside an enclosed area, creating the appearance of a vacuum or an area in which the pressure is extremely low.

The purpose of the vacuum pump is to produce and draw a vacuum in a particular amount of capacity provided. It creates the vacuum through the drawing of gas molecules in a specific size and then leaving an incomplete vacuum.

How does a vacuum pump work?

In the end, each vacuum pump functions exactly the same way. A vacuum is created through means of transporting the majority of liquids or gas molecules out of a particular area through a change in pressure from another area.

In the end, the region left with fewer molecules will experience lower pressure or a vacuum; in contrast, the region that has more molecules will have a higher pressure.

This is the reason why the Magdeburg hemispheres were not disintegrated by the immense forces imposed on them by horses’ teams. They weren’t kept together by the low pressure inside of them. Instead, they were compressed due to the pressure of the air around them.

The vast majority of the vacuum pump function in accordance with three fundamental concepts that are the foundation of positive displacement, or momentum transfer, also known as entrapment.

Both acceleration transfer or entrapment pumps are utilized to create a high and ultra-high vacuum; however, they require a large amount of energy and upkeep and, consequently, are expensive to run.

However, most commercial and industrial vacuum pump applications are met through positive displacement pumps like the Rotary screw vacuum pumps manufactured by Kaishan.

With the reliable, stable force from twin-screw or helical screws to remove a sealed chamber and create a vacuum. The demands of everything from the production of high-precision semiconductors and packaging in the food and beverage industry are met with a high degree of reliability and cost-effectiveness.

Furthermore, our vacuum pumps are an essential part of glass and metal processing, printing, stone cutting, plastic injection molding, and manufacturing of aviation equipment — to name some of the latest processes that depend upon Kaishan equipment and technologies.

2 methods to make a vacuum pump

Method 1: Using a Syringe and Tubing to Make a Pump

Get a syringe, three one-way valves, a hot knife, and some tubing:

Choose 3 tiny 1-way valves that are used for bicycle tires. Then take out a hot knife that has an edge that is the same dimensions of valves. Also, pick up a needleless syringe of 50-60mL and 12-inches (30 centimeters) or more tubing made of plastic that is the same size as the valve.

  • Certain valves measure 6 millimeters, while others have 8 millimeters. Both are fine; However, the plastic tubing should be the same.
  • They are available at many drug stores. Select the one that doesn’t have needles that are leaking out.
  • Find hot knives in craft shops or at home improvement stores.
Burn a hole in the syringe’s side:

Replace the tip on the knife that is hot to a round trip, which is similar to the size of the valves. The knife should be plugged in to get it heated up. Carefully pull the plunger back onto the syringe for approximately one inch (2.5 millimeters). When the knife is heated and hot, you can place it on the syringe’s side and create a hole in the space created by shifting the plunger. The exact position does not matter. Just make sure it’s nearer to the edge of the syringe rather than the plunger’s edge.

  • Make sure that the hole is as small in order for the valve to fit inside the syringe with a snug fit.
Place the valve in the hole you just created:

Remove the cap that is black from the valve’s top. Turn the threaded portion in the valve to the entry point. Continue turning it to the left (clockwise) until it is deep as it can go inside the hole. You’ll have the top of the valve hanging in the syringe. In this instance, it might assist in squeezing a tiny superglue on the valve to help seal the pump.

Slip a one-inch (2.5-centimeter) piece of plastic tubing over the syringe:

It is not necessary to be exact with the length. After cutting it, place it on the syringe’s top to ensure it is positioned with a tight fit. It is helpful to put some superglue around the edges to help keep it in position.

Insert another valve’s non-threaded side into the tubing:

Make sure you push it to its limits. It will eventually touch the lip. When you see it, let it stop. You might need to use pliers to assist in putting through the pipe.

Some individuals skip the tubing entirely and simply put the valve in the tip of the syringe. It is possible to test both methods to determine which one works best for you.

Attach tubing to the valve’s threaded end:

You can use the length you want to use you want, but make sure it’s enough to get to the pressure chamber after it’s been threaded onto the tubing it to the valve on the pressure chamber to finish the process.

  • A quick and easy method to build a pressure chamber to fit the vacuum machine is to make an opening in the top of a canning container and then place the thread of a bicycle valve inside the hole. The edges will be sealed with superglue or silicone gel.
  • To make use of the vacuum, begin by pulling the plunger almost to the top and then pulling it out until close to the top of the syringe in order to create the vacuum.

Method 2: Using a Bicycle Pump to Make a Pump

Remove the bicycle pump’s top section:

In most cases, you’ll only have to locate the screws that secure it in position. It could only have one screw. Make use of a screwdriver to pull the screw, then pull the inner components of the pump to reveal them.

Rotate the packing to the opposite side of the piston rod:

When you turn on the bicycle pump, the rod will be on the inside, so the moment you take the rod out, you’ll notice it. If you take out the rod, you’ll notice a small disc on the other side. This is what creates the vacuum inside the tube. 

Instead of being able to blow air into the tube, it is necessary to pull it out. The packing should form an u-shape that is facing downwards when you take it out. You can remove it by unscrewing the disc’s bottom part of the disc, then turning it to face upwards instead. Fix the disc’s bottom back in the correct.

If your model doesn’t include this component, another alternative is to remove the disc, then flip it over to screw it back in. If the hole doesn’t extend all the way around the disc, it’s possible to cut it through using an identical dimension.

Replace the rod in the canister:

The disc should be lined up to the rod’s inner side. Start at a 45-degree angle first when you pull it in so you will feel less pressure to the tube. Push it in the opposite direction back to your cylinder, making sure it is straighter as you go further down.

  • Take your time if you have to, as you don’t want to cause damage to the bicycle disc or pump in the process.
Disassemble the tube’s head that usually connects to the bike tire:

Continue the tube until the end and locate the head. Utilize your fingers to loosen it. If it isn’t able to be unscrewed, easily take the head off instead by cutting through the tubing that lies below it.

  • Make sure you create an even cut on the tubing so that it can be able to connect better to the vacuum chamber with greater ease.
  • Once the cutting is done after which the vacuum pump is finished.
Connect the vacuum chamber valve to the pump with the hose:

Once connected, lift the pump to create the vacuum inside the chamber. Then, pump it down and up multiple times to build up the strength of the vacuum.

  • If you’re creating the vacuum chamber, consider making a hole in the lid on a canned container that is just large enough to hold the straw. Put chewing gum in it to secure it, and then connect the tubing from the bike pump onto the straw.

The technology of a vacuum pump

Milking equipment consumes a significant amount of energy in dairy farms. However, there’s a method to cut these energy costs by half. Variable Frequency Drive (VFD) controllers are devices controlled by computers that modify the velocity of the motors the pump utilizes to maintain the vacuum level. 

Pressure sensors are positioned in the vacuum line that is close to the receiver’s jar. It connects with the VFD controller, which continuously checks the level of vacuum and adjusts the speed of the motor in accordance with the level of vacuum. 

Research has found that energy consumption during milking could be reduced by 60 %. It makes the use of a variable speed vacuum pump one of the most effective choices you can make to improve your dairy.

The benefits of using a variable speed vacuum pump are the following:

A milk pump consumes at least half as much energy as a car:

It is the VFD that determines the speed of the motor needed to maintain the value of the point vacuum level within the vacuum system. The VFD reacts to this by reducing or expanding the velocity of the motor.

The pump could be operating at a small fraction of its capacity in normal operation, which is almost all the time. This could drastically reduce the energy consumed. Research has found energy savings can range between 30 percent and 80 percent, with an average saving of 60 percent. Variable-speed drive systems can differ in appearance.

Only as rapidly as is required by the motor:

Prior to the time that variable speed vacuum pumps were created, the dairy owners were forced to operate the pumps at an incredibly high speed. Usually 7-10 cubic feet every minute (cfm) for each milking machine. It was widely believed that a fast motor is essential to regulate the pump’s level, enhance vacuum stability, and clean the system. 

Recent research has revealed that the volume of airflow required to ensure “steady-state” milking -which is where the milking units are all connected with no squawking teat cup or air leaks is as low as 1.5 to 2.5 CFM per unit.

Maintaining a constant vacuum:

A vacuum pump that is connected to the VFD responds quickly and generates the vacuum level with minimal variation. Also, the level of vacuum remains constant even when the motor’s speed fluctuates. 

If a milking device is damaged or the system is in need of repair or leak, the VFD immediately accelerates the motor of the vacuum pump to get rid of air. Variable-speed vacuum pumps keep the level and are often better than traditional systems.

The life of your vacuum pump will be extended:

The vacuum pumps running at their maximum speed will have less time to run when compared with one operating at a lower speed. Running a vacuum pump with lower RPMs is less demanding on bearings as well as other internal components, which could prolong the lifespan of the pump.

The motor will make significantly less noise:

A vacuum pump with VFD controllers can often perform at half the RPMs it would work without a VFD. Also, lower RPMs are more gentle on the ears.

In just two years, it will pay for itself:

The amount of money you save when installing a VFD relies on a variety of factors. The most important is the size and the type of the vacuum pump, the size and kind of milking system, and the time needed to milk and wash every day.

 A typical dairy milking three times per day or longer than 6-8 hours per day is sufficient to justify a variable speed pump based on energy savings.

Reduce costs by using less electricity in your dairy. A WPS agricultural advisor will help you estimate the potential savings and address questions regarding VFDs with variable speeds. The VFD pays for itself within just a few years; you’ll pay less for electricity throughout the process.

Final thought

It is possible to make an air pump to seal packages or even conduct experiments in science. The most simple method to make a vacuum pump involves using tubing in a syringe and turning the disc around on the bicycle pump.

A vacuum pump is quite complicated to maintain. This article not only shows you how to construct an air-tight vacuum pump but how to maintain it easily.
