Grease Gun Choose
Lubrication with grease, which is widely used today and is among the three different lubrication methods; It undertakes main tasks such as reducing friction, protecting against corrosion and transferring heat.
Of course, our biggest assistant while performing these operations is grease pumps. Grease gun; It is classified under four main groups as air, mechanical, hand-push and electric. The most frequently used and encountered pump group are air grease pumps.
It alleviates the workload of our customers and offers solutions in maintenance workshops, construction sites and stages, mines, agriculture sector, aviation industry and various industrial industries.
HORUSDY Grease Gun are divided into four groups as 10 kg bucket, 16 kg can type, 30 kg bucket, 50 kg bucket and barrel type according to their capacity, and two groups as 45:1 and 70:1 according to the pressure ratio. The advantage of the air grease pump is that it can be adapted with many optional parts to maximize its capability.
Grease Gun
Bucket capacity should be selected according to grease consumption and pressure ratio should be preferred according to workload. For example, if a user’s lubrication frequency is once a week and the amount of grease used is very low, tin-type pumps should be preferred.
Thanks to our models that can be easily adapted to standard grease cans, ease of transport and storage is offered to our customers. It is the pressure ratio preference that is more important than the capacity in the grease pump selections and most of our customers have had problems as a result of the wrong selection.
Pressure ratio, also known as compression ratio, is a factor that affects grease lubrication and directly contributes to the success rate of lubrication.
So what is meant by the pressure ratio?
The volume of the cylinder movement is determined by the product of the piston diameter of the pump and the dimensions of the piston movement distance. And the value obtained at this distance affects the efficiency/pressure ratio at the exit point of the pump. Therefore, while the pressure is high and the efficiency value is low in large diameter pistons, the pressure is low and efficiency is high in low diameter pistons.
Starting from this point, our pumps with a compression ratio of 70:1 should be used at points requiring high pressure, while pumps with a compression ratio of 45:1 should be used in low pressure and simple operations.
45:1 pumps can be easily used in maintenance workshops, auto services (passenger cars), small-scale enterprises, lubrication of equipment such as lathe, cnc, drill and bearing lubrication.
On the other hand, 70:1 pumps should be preferred in construction sites, concrete mixers, concrete plants, wind turbines, mines, aviation industry and industrial enterprises.
For example, on the dumper of the earthmoving truck or while lubricating the trailers, the grease gun connected to the grease nipple is exposed to counter resistance during the lubrication process. High pressure is needed to break this resistance and to make the lubrication process continuous.
Problems
Another feature that makes air grease pumps useful is their easy use. Working with 6-8 bar air pressure, these pumps provide lubrication without applying excessive force thanks to the grease gun.
Thanks to the spiral hose that can be adapted to the grease gun, access to difficult points can be achieved. In addition, the grease hose, which can be extended up to 20 meters, allows lubrication without moving the pump to another point within the maintenance area.
In addition to the above-mentioned function types, high-speed grease transfer can be performed from one point to another with pumps with lower pressure and higher efficiency options.
With pumps with a 1:1 pressure ratio, the grease flow has been increased up to 15 kg per minute. With these pumps, not only grease, but also liquid oils with very low viscosity can be transferred.
Another type of grease pump is mechanical or hand-push grease pumps. These types of pumps are used in simpler areas that do not require pressure. It is often seen in repair shops and companies that make mechanical repairs around you. It is preferred due to its ease of use, easy portability and functionality. However, it cannot be used for the pressure values mentioned above and the corresponding lubrication processes.
Result
Electric grease pumps, on the other hand, are generally used for filling the lubrication chambers of construction machinery or lubricating certain parts of construction machinery.
The fact that it does not need compressed air due to its working principle brings your productivity to the fore under adverse conditions. It adapts to all working conditions with its 24V, 220V and 380V options. The compression ratio is lower than that of air grease pumps. For this reason, its lubricating ability is limited to certain parts.
