Grease press function: How does this tool actually work?

Lubricating presses are tools that are used to refill and apply lubricants , more precisely, lubricating grease. The achieved lubrication is essential for the low-wear operation of machines of all kinds. The application is not limited to the industrial sector, but also in the leisure sector, a sufficient lubrication of bearings and sliding surfaces is of crucial importance. Are you in possession of a bicycle, an excavator, a trailer, a tractor or a construction machine? Then you should take a closer look at the current models.

Grease guns function as a pump by delivering the much-needed lubricant to the machine's wear-prone components. The energy required for the pumping process can be provided by muscle power, by compressed air or by electrical energy in the form of a battery. Each variant has, as so often on advantages as well as disadvantages, which are briefly listed below.

To really get the grease into place, most machines have so-called grease nipples to attach the grease gun . No worries, these are usually very recognizable. So that even hard-to-reach grease nipples can be achieved safely and without acrobatic master lines, most presses have a flexible hose tube.

The hand-operated lubricating presses: Price / performance champions in the grease gun comparison
These models are the simplest and cheapest variant of this tool class. These lubricators require muscle power to apply the necessary energy to move the grease from the cartridge to the appropriate sliding surface of the machine or vehicle via the grease nipple. Therefore, it is not surprising that only a relatively low pressure can be built and lubrication of several lubrication points can be quite exhausting. For this reason, the manual lubrication press is mostly used only for smaller, less demanding applications. Below you will find the best selling models in comparison.

Battery Presses: Maximum mobility and flexibility
In this variant, the lubricant is pressed out of the tube via an electric motor . The energy is thus no longer based on the muscle power of the user, but on electrical energy that is provided via a battery available. The battery is as mobile as with the hand-operated grease guns, but the higher and more even pressure can lubricate many and complex lubrication points. By eliminating the lever system, these models are also still very compactand thus well suited for confined spaces. Thus, these tools are always well suited, for example, if you have to lubricate hydraulic cylinders in the field, or apply grease to frequently changing vehicles.

Rating of DVRs with a radar detector - choose a high-quality device

Criteria for selecting a reliable DVR with built-in detector
Before choosing among the variety of models and manufacturers an appropriate device with parameters and capabilities with a detector that will be able to simultaneously and most accurately perform several tasks at once, you need to pay attention to a number of criteria, namely:

Design features and dimensions.
Hybrid DVRs can be of several types and differ in the type of mounting and capabilities. The most common standard options are of a compact type, which are installed on the windshield or rear-view mirror, but some car owners prefer remote cameras with which you can receive and process several signals from different cameras at once.

Viewing angle
One of the most important parameters that you definitely pay attention to when buying a DVR. It depends on him how much information will simultaneously enter the frame. The angle should not be too large and not too small; the optimal indicator is 130–170 degrees. Such devices read all road signs in the direction of travel, clearly see the markings and some of the cars in the neighboring lanes. Increasing the angle leads to reduced opportunities for detailing the resulting image, especially for DVRs, which belong to the budget options.

Display and video recording quality.
A good and easy-to-read display with optimal diagonal, brightness, clarity and convenient functionality allows you to quickly and efficiently adjust the camera position, adjust the GPS, radar, photo mode and other useful functions of the device. The resolution of the image obtained during the recording process depends on the power of the processor installed in the DVR and other technical features of a particular model.

When choosing a recorder 2 in 1 or 3 in 1, you should pay attention to the presence of the function of the loop recording, which allows you to save on the SD memory card. An important factor will be the price of the device. As practice shows, the most expensive devices are not always the most effective in work, while a properly selected model (based on expert opinions and car owners' reviews) from the budget category with a modern processor and optimal parameters can last much longer.

Rating of DVRs for reliability and quality
When choosing the best devices from different price categories for comparison and drawing up the final rating, our specialists paid attention to such basic parameters as:

the level and quality of identification of cameras and radars of mobile and stationary standards;
viewing angle and resolution of the recorded video;
recording speed and sensitivity indicator of the built-in detector;
uninterrupted operation and clarity of the GPS device;
