The Surface Cleaneris one of the most effective ways of cleaning surfaces that are mostly flat with power washers. This is a very modern machine that is normally designed with two or three arms. These arms extend from the top of the machine to the bottom where they are attached to shafts. These shafts spin around counter clockwise at very high speeds.
 
The shafts are equipped with spray nozzles on the bottom of each. The cleaning solution is expelled through the arms and out the sprayers as the shafts are spinning around. These shafts are located close to the surface to add to the intensity of the cleaning. Some of the Surface Cleaners have a shield around the bottom of the machine to help control the overspray. The surface cleaner gives the surface a deep cleaning that can not be achieved quicker then more traditional methods, such as power washers alone.
 
 
Using the Surface Cleaner
 
Using the surface cleaner is very simple. Once you have everything ready to go and have added the cleaning solution you are ready to start. Then all you have to do at this point is walk behind the machine and work the controls. The machine has a handle that releases the cleaning solution through the arms to the spray nozzles located on the bottom of the shaft.
 
Below is a list of some of the places that can be cleaned with power washers and a surface cleaner.

The surface cleaner will eliminate any streaking or missed spots that other cleaning methods can leave behind.


Benefits of Using a Surface Cleaner

There are a lot of benefits to using the surface cleaner. For starters, they are simple to use. They are also a very effective way to clean so when you are finished you will be able to look back and see the difference your efforts have made. When using a surface cleaner it will not take as long to get the job done as it does with other cleaning methods. This allows you more free time to take care of other vital business.
 
They are also very cost efficient to use. For instance, it takes less people to do same cleaning job so this can save you money and since they are so much quicker they also help to save on energy. power washers with surface cleaners can use hot or cold water depending on the job you need done. They help to keep flat surfaces looking clean and like new.

Complex aluminum parts often leave behind burrs during the manufacturing process. Burrs can be located deep within tough to reach holes, or in more accessible locations along grooves. No matter where they are located, it is necessary to remove these burrs before the product is finished. Hydro de-burring is a process that can the removal of these burrs more efficient, while also making that removal repeatedly consistent as well.
Hydro de-burring machines use high-pressure water jets, that direct water at pressures ranging anywhere from 1,500 PSI to 7,500 PSI using from 5 to 30 GPM solution flow to knock away burrs at their root, leaving the part burr free. These machines are able to break off the burrs and blow away the residual chips, but they are not a miracle solution to all problems. Hydro de-burring cannot mechanically machine off the burrs, it does not leave behind a smooth end, nor does it make rounded edges. The manufacturer will need to continue whatever process they are using to achieve those ends once the de-burring unit is installed.
Although a hydro de-burring unit is limited in its ability to accomplish the goals listed above, it is effective in many other areas. For example, it effectively removes heavy grease and oil. Also, high pressure spray impingement can take off paint and knock out embedded sand and dirt. Pockets of embedded chips are also removed from the part, along with solvents left over from the cleaning process.
Hydro de-burring uses a system of hydraulically powered rotary high pressure water jets, which shoot water at a straight, 0 degree angle. This allows the water to hit the part at a right angle, ensuring that the jets will travel into any hole on the part as deep as possible.
The effectiveness of hydro de-burring depends on three factors. First, the volume of water used. It must be enough to have the power to knock off the burrs. Second, the speed of the water propelled through the jets must be sufficient. And finally, the thickness and type of burr that is being attacked. The thinner the root of the burr, the more effective the process will be. Larger burrs will require more water and higher pressures to be removed. A excellent test to determine if the burr being removed is of the right size is the pencil test. If a burr can be removed by a . 5mm diameter pencil lead that is 9. 00mm long without damaging the lead itself, then the burr can be removed with high-pressure water.
Hydro de-burring is an effective and efficient process, but it is not ideally suited for all manufacturers. Not all metal cutters leave burrs in the same location every time. In these cases, brushes and media tumblers are a better choice for the company. Hydro de-burring is effective, but it should not automatically be considered the best option. If the burr is not consistently placed, the jets will not be able to remove the burr all the time. If it is, the hydro system will remove it consistently and effectively.
Therefore, if a part has consistent placement of burrs, a high-pressure direct spray system is appropriate. An example of this can be found in an automotive transmission plant. An aluminum valve body, once milled, is left with a consistent roll over bore in the spool bore. A power brush cannot access the hole where the spur is located. A probing brush may be able to access the burr, but there is the chance that it will hurt the machined surface of the part and render it scrap.
A high-pressure water stream can shoot into the hole and knock the bore off with precision. It can then flush the burr out, and do no hurt to the machined surface. Assuming the burr is formed in the same spot in the prior stages, the high-pressure water system will deliver the best quality possible every time.
With this quality comes a high cost. Properly engineered high pressure deburr systems cost at least $500,000 or more. The high cost can be attributed to the bought components and customer driven plant safety regulations. Many of the parts necessary for a high-pressure system can cost upwards of $5,000. Hydro de-burr systems require parts such as:
-High Pressure Pump
-High Pressure nozzles and manifolds
-High Pressure tubing and hoses
-Filtration
-Oil Separation
-Fixtures to hold part in place
-Sound dampening measures
All of these parts can be expensive. But, if the hydro de-burr system is able to remove burrs quicker and simpler than a wire brush system on a particular part, it is well worth the cost to invest in the unit. The guaranteed removal of burrs combined with the lack of hurt to the part itself (wire brushes can remove burrs but also inflict hurt on the part) will help the manufacturer recoup their initial investment through production of high quality parts.
The high pressure system comes in many different types of machines. Manufacturers can pick from robotic transfer, conveyorized pallet, rotating dial table, chain driven, belt driven, manual, and automated machines, depending on the needs of their specific plant and part. They also include part drying and blow off stations, to ensure that the part received when finished is clean, burr-free, and dry.
Hydro de-burring is especially well loved within the automotive industry. Producers of oil pumps, engine blocks, valve bodies, transmission components, and crankshafts are among the users of hydro de-burring units. Any company with a repeatable, consistent burr production in their parts should consider a hydro system to make their production process better. If the money they will make from delivering a high-quality end product is worth the cost of the machine, then it may be time to invest in a hydro-deburring unit.

The Firbimatic washer allows manufacturers to use solvent cleaning in their plants while still adhering to environmental regulations in place to limit solvent use. The Firbimatic is designed with these specifications in mind, and controls the environmental impact of the solvent used.
The machine is hermetically sealed. Parts are loaded manually or by an automatic pusher into the process area, where solvent spray is applied as a pre-wash/yucky cleaning cycle. Solvent for this first step is obtained from a storage tank, known as Tank #1.
The solvent spray removes up to 70% of the soil from the parts, and then is pumped into the still for the distillation process that separates oil from solvent. The still is heated via plate and frame steam heat coils, which warm the solvent until it becomes a clean solvent vapor. In the first still, the oil is reduced to a level with 15% solvent. The vapor is clean due to the fact that the oil (or lubricant) cleaned off the parts boils at a higher temperature than the solvent. The solvent is sent to a second still, where the remaining oil is boiled. In industrial applications, virtually all of the solvent is boiled out of the oil using this dual still system. When the sill is not cleaning solvent from the pre-wash cycle, it is still running. The still is operating continuously, drawing from Tank #1 and boiling the solvent to vapor, and then directing it to the condenser.
The soil not boiled in the still travels via closed plumbing system into a storage drum, where it waits to be hauled away by a licensed hauler. Using a qualified hauler keeps the soil (with less than 5% solvent content) from contaminating the surrounding environment.
The clean, vaporized solvent moves to a chiller, where a plate and frame exchanger uses chilled water to condense the clean solvent vapor back to liquid form. The liquid solvent is then stored in a second, smaller tank, where it is kept until the final fluid rinsing stage.
In the immersion stage, after the pre-wash stage, new solvent is drawn from tank #1 and pumped into the process area for submersion of the parts. The parts are covered completely in solvent, and at this point different mechanical actions can help in the cleaning process. The basket can remain still, it can oscillate back and forth to go parts in the basket, or the entire load can be completely rotated on a constant basis to provide a more aggressive action. Also, a vacuum can be used to remove air bubbles in the process house so that ultrasonic action can be more effective.
The process development team determines the appropriate mechanical action after evaluating the design of the part to be washed. Once the submersion is complete, the used solvent is returned to the holding tank #1, where it is eventually drawn into the distillation process.
In the next stage, the parts receive a final solvent fluid rinse. The solvent that has been cleaned, vaporized, re-chilled and directed to tank #2 is used to rinse the parts before being pumped back into storage tank #1.
Following this fluid rinse, the parts are then subjected to a clean solvent vapor rinse with that vapor which is generated from the still. The vapor becomes fluid again when it comes into contact with the parts and removes the remaining soil. The vapor also warms the parts to prepare them for drying, and the condensed vapor returns to tank #1.
Once this cycle is complete, the parts are ready for the drying cycles. Using an electric fan, airflow is generated across the heated steam coils and into the process area to facilitate drying. The air is driven out of the process house and moves along the chilling coils to cool back down before it passes through the fan again. This cycle of air continues for a pre-determined duration to assure adequate drying is accomplished.
The heated drying cycle is followed by the vacuum drying cycle. A vacuum pump lowers treatment chamber pressure, which allows for the solvent to boil at a lower temperature. Therefore, the remaining solution is evaporated from the parts at the lowest possible temperature.
Charcoal absorption is the next phase in the process. This process assures that no solvent fumes are able to exit from the process area to the operator area. A fan directs air circulation through a Coalperc activated carbon recovery unit, which filters the air to remove solvent fumes. Once the concentration in the chamber is below 1g/m3, or 150 PPM, the process area door can be opened and the parts are removed.
