How Does A Vacuum Pump Actually Work?

maj News Hydro Vacuum Excavation, vacuum excavation

We don’t really think about vacuum pumps and how important they are until we need them. For the average person, you only think about a vacuum pump when you are having trouble with your plumbing, especially the toilet, right?

Outside the usual residential plumbing problems, vacuum pumps are used in many things, mostly in construction.

They work by pumping or moving gas or liquid and in some cases solid, molecules out of one area by using pressure. They work on three principles – entrapment, momentum, and positive displacement.

Following are the

1). Entrapment Pumps

Entrapment pumps use chemicals and apply them to the container or area that needs to be vacuumed. They also use cold temperatures to condense gases into a solid or absorbable state.

Once the molecules react to the chemicals, they are then removed by the entrapment pumps. Entrapment pumps are usually used alongside momentum transfer pumps and positive displacement pumps.

2). Momentum Transfer Pumps

Momentum pumps use high pressure to pump out the materials you want to vacuum. They use high-speed jets of fluids or gas depending on the need. There are two types of momentum transfer pumps:

Diffusion pump – blows out jets of oil
Turbomolecular pump – uses high-speed fans

3). Positive Displacement Pumps

Positive displacement pumps create low vacuums by expanding the volume of a container. They expand a cavity to allow clogged materials to flow out.

The expansion reduces the pressure allowing the molecules to flow out of the container.

4). Regenerative Pumps

Regenerative pumps are rotodynamic machines that utilise vortex behaviour of fluid or air. It uses the principle of energy transfer from a moving rotor to gas in the channel of the pump.

They are usually used to increase pressure in water networks in car wash installations. They are popular in the chemical industry and mechanical engineering.

5). Venturi Vacuum Pump

A venturi vacuum pump or aspirator works by using compressed air running through the pump. It has no moving parts. It reduces pressure from a “choke” or constricted area so fluid can flow through.

Venturi nozzles and tubes are used alongside the pump to elongate the exhaust section of the pipe.

The vacuum effect becomes stronger when the exhaust section of the pipe is extended longer. The longer the pipe the stronger the vacuum.

6). Steam Ejector

A steam ejector has no moving parts. It is a simple pumping device. This is a simple, reliable, and affordable vacuum device.

It uses fluid or gas as a source of force which is called steam jet ejector. Steam ejectors are most popular in the chemical industry.

Two major functions of Steam Ejectors:

Single-stage steam ejectors
Multi-Stage steam ejector

These types of vacuums are further classified into the following:

Liquid Ring Vacuum Pump
Single Cone Vacuum Pump
Close Couple Vacuum Pump
Two-Stage Vacuum Pump
Chemical Process Pump
Twin Lobe Roots Blower
Rotary Vane Pump
Diaphragm pump
Piston Pump
Scroll Pump
Screw Pump
Wankel Pump
External Vane Pump
Roots Blower or Booster Pump
Multi-Stage Roots Pump
Toepler Pump
Lobe Pump

The measure of the performance of vacuum pumps is its pumping speed. Achieving a high vacuum can be challenging because of factors like outgassing and vapour pressure changing constantly.

Materials like grease, oil, rubber, or plastic gaskets, also affect the efficiency and strength of the vacuum.

The good news is, you do not have to worry about the technical processes. There is no need to worry about what type of pump you need.

What Are The Main Benefits Of Vacuum Loading?

Are you looking for a safe way to remove and dispose of sludge, hazardous liquids, and even fine loose materials? Are you limited by space and unable to use traditional methods of removing debris? If so, you should look no further than vacuum loading.

Vacuum loading uses a vacuum truck consisting of a pump and a tank. The pump provides suction with enough power to suck materials and deposit it in the storage/carrier tank.

The truck transports the debris to the approved deposit site for safe disposal. By using vacuum loading, you stand to accrue the following benefits:

It is cost-effective
Vacuum loading is faster than traditional loading methods
It accords personnel with better safety
Vacuum loading is versatile enough to in use a wide variety of scenarios

Vacuum Loading Is Cost-Effective

For debris recovery, vacuum loading has the notable benefit of being cost-effective. The main contributing factor is that vacuum loading does not involve the deployment and use of many machines.

The vacuum loader truck comes fitted with everything it needs to complete a job. For instance, the vacuum pump and debris tank are installed onto the truck. As such, you can vacuum material and transport it using a single truck.

Therefore, the associated cost of recovering and disposing of materials is reduced significantly. Additionally, the improved efficiency associated with vacuum loading increases the cost-saving for end users.

Vacuum Loading Is Fast

Unlike other material recovery methods, vacuum loading is exceptionally fast. Since the process of vacuuming uses a single truck for the entire process, it is much quicker.

For instance, the recovery equipment does not have to recover and load the material into a different vehicle, which is a time-consuming process. After the recovery of the material, it is diverted into the tank in a single operation.

It Is Much Safer For All Involved

The safety credentials of the vacuum loading process is another significant benefit. The personnel need only direct the vacuum hose to the material, and the vacuum pump sucks the material.

This reduces the risk of materials hitting users. The personnel can even set up the vacuum hose for remote material removal, further increasing their safety.

Vacuum Loading Is Versatile To Use In A Wide Variety Of Extreme Environments

In some cases, vacuum loading is the only material recovery method you can use. For instance, if you are working in confined spaces, traditional methods of debris recovery such as using diggers or a backhoe are quite simply untenable.

However, it is in such environments that vacuum loading comes stands out on its own. It allows users to excavate material in confined spaces without the need for a lot of space for the equipment.

The same applies to excavation projects involving hazardous materials and gases. As mentioned above, vacuum loading is much safer for the personnel as they do not have to come into contact with excavated material.

In some cases, the excavation personnel can work remotely, reducing the chances of inhaling hazardous gases. Vacuum loading also has the unique advantage of helping negate the adverse effects of spillages.

If a spillage is left unchecked, dangerous material percolates into the ground, affecting groundwater and soil quality. Vacuum loading allows emergency personnel to recover the material efficiently.

Additionally, you can use vacuum loading in projects such as hydro mud, marble slurry, concrete and drill slurry removal, drain cleaning, vessel, and tank cleaning, pile, pier, and bore cleaning, and much more.

As such, even when you cannot use other excavation/recovery methods, you can still rely on vacuum loading for your project.

Conclusion

Vacuum loading has excellent utility in industrial, commercial, and construction projects. As a material recovery method, it has a lot of benefits that other excavation and recovery methods cannot attain.

Why Use Vacuum Loading In Confined Spaces?

maj News high powered vacuum systems, Hydro Vacuum Excavation, vacuum excavation, Vacuum Loading Confined Spaces

Do you a confined space that needs cleaning or clearing? Confined spaces are not only difficult to access but they can also be very hazardous. Let’s take a look at the best method to use in these situations.

Confined spaces are completely or partially enclosed areas that have restricted entry. Often there is a lack of oxygen or a space that contains atmospheric hazards such as toxic gases.

In areas where machinery cannot gain access to a confined space, vacuum loading and excavation is an extremely economical and efficient solution.

It allows work to be carried out safely and efficiently with minimum risk to workers or property. Materials are vacuum loaded from a vessel or open restricted space and transferred to a holding tank for safe disposal.

Work may be undertaken on a worksite or in a public space.

What Are Confined Spaces?

Confined spaces may or may not be big enough for workers to enter and include areas such as:

Pump stations
Manholes
Drains
Wet wells
Gross pollutant traps
Highly congested vehicle or pedestrian areas
Areas with overhead obstructions
Sumps
Storage tanks
Pits
Silos

Access to confined spaces is usually required for cleaning, inspection, repair, maintenance, or construction.

Vacuum loading services are employed where access is limited to remove materials such as waste stored in pits or tanks, for pit cleaning, during plant maintenance, or in flooding situations.

Cleaning of confined spaces such as drains, cesspits, and sumps requires specialised knowledge and equipment such as advanced, self-contained vacuum loading trucks for the safe removal of materials which may include liquids, lump or particulate solids, or gases.

Some materials may be hazardous such as flammable or explosive materials, chemicals or materials with carbonaceous particulates.

Why Confined Spaces Are A Concern

Working in confined spaces can be extremely dangerous for workers with high risk from things like trench subsidence and collapse or exposure to contaminated atmospheric substances.

The risk of potential financial burdens can be minimised by making use of qualified and highly experienced technicians and equipment to gain entry to confined spaces.

Benefits of Vacuum Loading in Confined Spaces

Using vacuum loading in confined spaces:

Eliminates the need for workers to enter restricted or dangerous areas to perform high-risk tasks.
Saves time and costs involved in obtaining permits as well as training required to perform high-risk tasks in confined spaces.
Is an extremely efficient and cost-effective alternative to manual labour which is often the only method employed in situations such as cleaning out tanks, pits or sumps.
Allows work to take place in restricted areas where conventional machinery cannot be used.
Materials are vacuum loaded and safely transferred into tanks with minimal threats to the environment or disturbance of the worksite and surrounding areas.
Quickly and accurately exposes damaged areas for inspection and repair.
Efficient and accurate operation minimises turnaround time and overall costs.

Applications

Vacuum loading services are excellent for the removal or recovery of wet or dry heavy products such as:

Brick dust
Concrete and marble slurry
Pit, waste, and stormwater clearing
Drill slurry, hydro mud, or NDD
