Grease Press Test: The best grease guns in comparison
A grease gun is an excellent tool for performing lubrication operations in a variety of job sites. These include, in particular, machines, engines or transport systems. Often in these areas you have to deal with hard to reach hubs, joints, rails or bearings that require special lubrication requirements. In order to grease the devices and machines properly, grease guns are used.
For intact machines Good lubrication is indispensable for the maintenance and longevity of aggregates and components in various sectors of industry, as well as in motor vehicles. With a grease gun can be pressed on the so-called grease nipple grease , for example, a bearing point. In principle, a grease gun works much like a pump, whereby a distinction is made in the design between shock and lever grease guns, which are operated manually, electrically or by compressed air. How does a grease gun work? A grease gun is composed of a solid metal housing, in the middle of which a cartridge with grease is inserted and secured. Depending on the model is usually still the slot for the compressed air tank or the battery, and the trigger. The grease guns available on the marketwork essentially the same: pressing the trigger lever creates a high pressure in the integrated cartridge. By this pressure, the lubricant through the attached grease hose, at the end of a lubrication device is attached, pressed. The lubricating device allows the grease to be safely and easily attached to the designated place. An additional bleeder valve on the grease gun ensures that the excess pressure is released.
What differences are there with grease guns? For manually operated grease guns , the lubricant must be metered by hand. In contrast, the electric grease pressesdeliver a precisely metered amount of lubricant at the touch of a button. Shock-grease presses are very easy to operate because the pressure exerted on the lubricating pipe increases the internal pressure of the press. The fact that the grease exits the mouthpiece of the press, the pressure is reduced. Similarly, the hand lever presses work, with the difference that the pressure is higher due to the leverage effect. When buying a grease gun, it should be noted that the supplied mouthpiece also fits the grease nipple of the machine to be machined. Finding the right mouthpiece can sometimes be very complicated. One way to get around this is to replace the machine's grease nipple with a standard one.
Bleed screws for easy operation Some machines are equipped with bleed screws, through which the old grease can escape as soon as it is pushed out by the newly entering grease. For other machine types, the amount of grease to be introduced periodically is defined very precisely. The most common type of grease gun is the hand lever grease gun, which has the advantage that with a stroke, a larger amount of grease can be introduced, as for example with a shock press. In addition, there is another advantage of the manual lever grease press in the filling method. Most pad presses need to be filled by hand, whereas the tube-type hand lever presses are uncomplicated using standard 400 gram cartridgesclean and comfortable can be filled. Hand lever presses are made of a wide variety of materials. From plastic models to sheet metal grease presses to stainless steel models.
Stable models for high pressure If the grease has to be introduced into the machine via a very high pressure, a very stable grease gun is required, otherwise there is a risk of the grease escaping from the rear screw cap or tearing the housing of the tool. If the grease presses are to be used continuously, for example in the industrial sector, and exact filling quantities are required, then usually electrical grease presses are used. Different versions To enable the application of lubricating greases even under difficult conditions, grease guns are available in different versions as a battery grease gun, compressed air grease gun or as a one-hand grease gun or hand lever grease press. For particularly heavy equipment, larger high-pressure grease presses are suitable, which work with very high performance and a large filling quantity. When choosing grease for grease gun, as well as filling the grease gun, the pressure resistance, water resistance and temperature requirements must be taken into account. Greases are usually added to substances, through which the susceptibility to corrosion is lowered and the devices are protected against premature wear. Mineral oil, which is usually thickened with a soap mixture, usually serves as a base material for the lubricant. A suitable grease is, for example, the Hightec Multipurpose Greasewhich can be used from minus 30 degrees to plus 130 degrees.
Grease presses with plastic pipe are very handy due to their low weight and can be operated pleasantly even in cold temperatures. The robust and corrosion-free material is particularly dimensionally stable and also withstands falls or other external influences. Hand lever presses with a shortened press tube, for example made of galvanized steel, can be stored in a particularly space-saving manner. The offered grease pressesThe different manufacturers sometimes differ greatly in their structure, in their field of application and in the requirements of the material. The material load on lubrication and the frequency of use are important aspects that should be considered when buying grease guns. It is possible to mount electronic controls on manually operated models, with which the desired amount of grease can be precisely metered. By means of hand lever presses, the amount of lubricant can generally be entered very precisely.
Headphones Meters Music OV-1B Ponte and (not) only?
I think it’s not necessary to explain, why are the headphones ideally suited to “stand up”? Unlike a smartphone, which you need to get out of your pocket, and watches that you need to look closely to understand what brand and how much they stand, headphones are always on their heads, they are big, bright, they are visible to everyone and at a glance Immediately clear: there is a dude babosiki or he is a “bum”. That's why people are wearing Beats, more precisely, so I wear Beats Studio 3 Wireless: purely to show that throwing 200-300 bucks on headphones is like blowing my nose.
Recently, however, too many people began to walk with expensive headphones, and although I have a Böse QC35, Sony 1000x and, as I mentioned, Beats Studio Wireless, no matter what I put on, I am still in the crowd outside I won't stand out for anything, because, well ... Everyone goes with them. And I want not like everyone else. And so I bought myself Meters Music OV-1B.
Headphones Meters Music developed by Ashdown Engineering, which is a manufacturer of concert equipment. In particular, their bass amps are used and used by bass players U2, TheWho, Black Sabbath and many others. As written on the official website: "The bass is in their blood." And yes, all their products are distinguished not only by brand quality, but also by firm style. On the front panel, in addition to all the switches and toggle switches, there is an analogue VU-meter installed (a “volumeter” is a device that shows the amount of sound) with backlight, and you won't confuse these bass amps from Ashdown Engineering with anyone.
And in the headphones Meters Music OV-1B there is also an analog “volumeter”, and, unlike bass amplifiers, in the headphones Meters Music OV-1B there is not one, but two analog VU-meters. Cool, in short! Here you walk down the street, listen to the music, and the "volumeter" arrow oscillates and shows how loudly you listen to the music. There is no practical use, because you yourself can not see the testimony of a "volumeter" while the headphones are on your head. And as it is clear that all these troubles only in order that the owners of Beats, Sony and Böse feel their inferiority, and they feel it to the full, they have no “volumetre”.
But not a "volumeter" single. Meters Music headphones have other nice features. They are available in two versions: wired OV-1 and wireless OV-1B. They do not differ in design, except that the "bluetooth version" buttons on the case anymore. Well, the design itself, of course, is impressive, it looks stunning from the side. Metallic chrome, all these smooth rounded lines - elegant and stylish at the same time. Headphones look massive, but they weigh a little (because they are not exactly metal, most of the body elements are made of plastic and simply painted with metal), but they sit very comfortably on their heads, well, just ... like you put a cloud on ... chic. Despite the fact that my head is not small and many headphones crush me, but here is just a holiday of comfort and relaxation.
Another important feature of the Meters Music headphones is the built-in active noise control. Both versions have this ANC, it works quite effectively (not as efficiently as Böse QC35, but much more efficient than Beats Studio 3 Wireless). But with this noise there are several problems. If you use headphones on a cable with the ANC turned off, the "volumeter" does not work and does not glow. Ie the on / off button of the ANC, it also looks like the on / off button of the headphones;
If Böse QC35 and Sony 1000x have an active “smart” ANC that adapts to external noises and approximately “understands” which frequencies are currently being suppressed, in Meters Music OV-1B the noise is not adaptive and does not compensate for individual frequencies of street noise, but “ stupidly cleans everything below 1kHz. Thus, street noise continues to make its way through the overall sound in some proportional amounts and you still hear the slight hiss of a working noise in the pauses between the melodies, and the sound itself changes greatly when the ANC is on, which can be clearly seen on the graph above.
The red line is the sound with ANC turned on, and the black line is turned off ... And these frequency response is just heaven and earth ... It turns out that if you use headphones with ANC turned on (well, so that the "volumeter" burned and jerked), you doom yourself to distorted sound with bulging low frequencies ... And if you turn everything off to get a neutral sound, you can forget about Ponts ... Frankly speaking, an unpleasant situevina ... But there is one positive point in all this: I like the bass head, sound with ANC and bulging bottom really like it and I'm roofing on this mode, use headphones, not paying attention to the "rustling" shumodava and street noise, this is easily possible to struggle, making the volume a little higher. And with the sound ... Well, damn, that's how I love. I just got an apple with these headphones. Yes, this is not a natural sound, but embellished,
Well, now the most burning question, which certainly worries everyone who reads it ... But are the headphones of Meters Music OV-1B worth the money that is asked for them, and they ask for nothing at all € 350 (I bought cheaper during discounts for 250 €) ... No, of course, they don’t cost 250 € ... First, they are too plastic, and the worst thing is that the hinge fixing the iron cups to the iron headband is made of plastic, and what happens over time where there are two iron parts connect one plastic, you yourself must understand. This is a clearly “programmed” defect. This hinge is the most mobile part of the design, and it is without a retainer, it collapses by itself ... In general ... only because of this I cannot recommend these headphones to anyone else to buy.
The second problem is the arrangement of the ANC and bluetooth buttons on the case: the impression is that the engineers were specifically looking for the most inconvenient place where these buttons could be plugged in so that they could not be switched while the headphones were on the head. And they stuck next to the holder so that you can grope, but you can not switch. Also, Meters Music OV-1B does not have NFC and you can’t quickly connect them to your smartphone using the “approach method”. For this price segment, the lack of NFC is strange. Well, here I am, buying headphones for € 250-350, I expect that they have their own smartphone application, where you can customize the language of the voice assistant, for example, or look at the battery charge, I'm not talking about the equalizer presets and other proprietary sound settings. I, using Böse and Sony, got used to the fact that a lot can be changed through a smartphone.
These obvious flaws seem to hint that the manufacturer does not yet have experience in developing headphones for mobile devices and does not quite understand that now there is a trend in the market, although the same Meters Wireless OV-1B wireless headphones already have support for the AptX HD codec , I mean technically they are at the most modern level. Even too modern: this AptX HD codec exists somewhere in nature, but I don’t have a smartphone, receiver or HiFi player that would support it. And I can’t enjoy its quality, I can only transfer music through the usual AptX codec, and in order to listen to music with it, I have other headphones and not for 250 €, but just for 50 €, and I understand how that all these references to AptX HD codecs are purely marketing and advertising. Again,
Well, this time the review will be short, the main thing I have already outlined. What I liked was a comfortable fit on the head, sound, as I like with an emphasis on the bottoms, and then you have a choice, if you need a neutral "symphonic" sound, then simply turn off the ANC, and they will sound like at a concert in Philharmonic. And, of course, Ponte 80lv in the form of two analog "volumeters". The name, of course, is cool, like “will” is measured, but I would call them as they are: “lamentmeter.” In fact, you are the one who fights with the owners of Beats, Sony and Böse, and you have more - look at the readings of the “lavemetra” arrow. This, of course, is a major plus.
But the minuses in the form of "a lot of plastic" in the finish and artificial leather, what ?! At a regular price of € 350, you could undress and pull a pair of bulls or sheep, this is a premium product, it should not only look beautiful, but also be felt in the hands of the upper class. And so it is a failure, but the main file is, a pancake, fastening hinges. They were confused with the handle of the cups fixing: it is casting, aluminum, this type is not so easy to make and needs to be processed later, but the hinge from cheap black plastic is so Deshmansky, I don’t rub it ... price category with Bowers & Wilkins PX and Bang & Olufsen H9, whose manufacturers did not save on pins, and specifically and clearly invested in the materials so that their users can enjoy the full and not participate in the lava-metrics.
