Statistics show that around 70 percent of damage caused to diesel generators is the result of pollution of the hydraulic system or debris in the computer system. Any professional engineer knows that the purity of the hydraulic oil is the key to lasting performance of hydraulic machines. But cleanliness – it is not all.

It’s equally important to choose the correct hydraulic fluid and to replace it properly (and regularly). This is what we will discuss today.

General recommendations

So, when selecting the hydraulic fluid two options should be considered. First of all – ambient temperature during operation. Secondly – the viscosity of the fluid in the operating temperature range. The second parameter is specified in the documentation of every individual machine. Some sources state that the viscosity of the hydraulic fluid depends on the type of pump that is used in the computer system. This is not entirely correct. The viscosity at operating temperature is calculated based on the bandwidth of the narrowest station in the hydraulic system, since the hydraulic fluid must have a certain rate of flow through these channels, otherwise hydraulics won’t operate properly.

Consequently, for many construction machines, using the very same versions of hydraulic pumps different types and manufacturers of hydraulic fluid are frequently utilized.

By way of instance, in contemporary hydraulic excavators, so-called “proportional” valves with very little cross section of the channel are used. The system is quite complex, with electronic control components. If you pick the wrong viscosity of hydraulic oil to your machine, the machine will not operate at full capability.

The recommended oil type is usually indicated in the cockpit on the particular information labels or directly to the tank of this hydraulic system near the filler neck. Now the modern machines frequently recommends utilizing high viscosity grade oil HVLP. This is hydraulic oil with a more contemporary package of additives compared to in oils class HLP. Oils of this class have more stable viscosity-temperature performance, and in severe cold conditions they work better. Manufacturers of these oils suggest the temperature range from – 30 to + 60 degrees Celsius.

In addition to stable temperature characteristics …


Before you know it you’ll be able to repackage China like a pro with our help.

When packing your china you’ll need a few materials, a stack of clean packing paper or unprinted newsprint a dish carton, a roll of packing tape,and a permanent marker. Now that you know what you need let’s jump right in!

China is packed in stacks,with paper layered in between.

Start by placing your first piece of china in the center of a stack of packing paper. Fold one half of a sheet or two of paper over it, and then place the next plate on top of the paper and the plate. Continue this process until you finish the stack:4-8 plates, depending on thickness. With delicate items like these don’t skimp on the paper. Fold a few extra pieces over the top plate,and roll the package together by bringing in the two sides in over the top and then rolling it over itself.

China should be packed standing upon its side in a dish carton. This is where the dishes have the most integrity. Also, notice that this carton has been padded at the bottom with crumpled paper and, as you can see, these types of boxes are extra thick and sturdy. You can pack lighter delicate items onto in the dish carton, like stemware but the heavier, sturdier china should be the base of your box. Use crumpled paper to fill in any gaps in the box; nothing should shift around. The box should be labeled”fragile” and “this end up.

Then, seal the dish carton with tape. Finish by labeling the carton with its contents and destination. By now, you should be an expert in packing china.
