High pressure pump for pneumatics with their own hands
This air rifle stand has a lot of advantages. In addition to its compact size, an excellent plunger mechanism deserves attention. In total, the device uses two filters of through-type. The boom is designed with a circular cross section. If you believe the reviews of experts, then the rod is deformed very rarely. The stabilization system is provided by the manufacturer of the second class. You can buy the model for 21 thousand. What should always be in the glove compartment of any car is a table of fines for traffic violations. Even if you do not violate the rules, there may always be a situation in which they want to attribute a violation and not a small fine.
Often on the roads there is a situation where you need to report to where it should be about the unscrupulous employees of the traffic police but it is very difficult to find the right phone number, and distract emergency services such as 911 and 02 on this issue is simply not correct. Below is a list of places to call on this issue.
On many auto forums there is a debate about where to get maintenance on a new car. Some people who have an expensive car and have a purse with a pretty sum, say that only the official dealer, others who do not have a super-cool car and can not especially luxurious, say that in a private service, t.к.
High Pressure Pump from a Jack by His Hands
Did the squeaky air gun, born in 1963, at the time of 10 meter shooting galleries, technical superiority of the Soviet Union, knew that on the 45th year of its existence, being a grey-haired old lady and unable to compete with the young Murka, it will be exchanged for a gas spring to an evil, pneumatic sawing amateur and will turn from an ugly duckling into a white swan. Can anybody imagine the chilling horror that gripped the poor fellow when CarrMan the Ripper was examining the state of his giblets and scratching his head at what he could make out of it:
The years had not spared the fracture: its main joint was suffering from terrible arthritis, there was no tightness at all, and severe lung cancer in the form of a tattered cylinder hinted at organ transplantation. What are we going to do?? a high-powered PPP with a big cylinder volume and a gas spring?. puzzled the pneumatic builder. there were two types of GPs, but there is a third type, so disliked by all GPs. central hitch of the piston: its immense power is not exactly what the son of a hunting Siberian with a good shot from nature aspired to All he wanted was a new rifle that would be if not more accurate than his, then at least at the same level as his. And this is possible where? In the pacEPE! Yes, but a PSR is 200-300 atm. where to get that kind of pressure? Well, in the process of researching website materials, the knowledge set, the pundit stumbled upon Muzzy’s article https://forum.guns.ru/forummessage/30/216338.html. (I highly recommend reading it, without it much will be incomprehensible). Here it is. That’s it, and with a pump. Strange why the topic stalled? I’ve seen what a man is doing and how he ended up with this life. Yikes. Mother, mother. habitually echoed ECHO. The standard way of developing an airgunner, was very similar to CarrMen’s. The first letter flew: (to my great regret my outgoing letters are gone, only : Re: incoming, most of which only part of my message)
How to make a powerful hydraulic drive from a starter motor and an oil pump from a tractor
Nothing gives you more compression than hydraulics. That’s why it is used in the construction of bending machines, elevators for cars, presses. Let’s see how to make a universal hydraulic drive from tractor parts, for almost any installation.
- Car or tractor starter;
- hydraulic pump 10 l/min;
- sheet steel 4-6 mm;
- 50 mm pipe;
- Profile pipe 150×150 mm;
- hydraulic distributor;
- Using a piece of pipe and a high-pressure hose;
- oil filter;
- hydraulic oil;
- hydraulic cylinder;
- fittings and adapters.
Manufacturing process of the hydraulic drive
The first thing to remove from the starter drive with an overrunning clutch.
It is disassembled to resharpen its pinion to mate with the hydraulic pump shaft. To do this, it will have to be heated to a red heat to release the metal. This will facilitate further machining and improve welding.
The pinion on the shaft is turned on a lathe. Then an adapter is welded to it for the splines of the hydraulic pump shaft. The drive with the overrunning clutch is then reassembled and installed in the starter motor.
Two adapter plates must be cut out of sheet steel, one for the starter motor and the other for the pump. They are then welded together using a piece of pipe. This provides a firm grip.
From 150×150 mm profile pipe to make an oil tank. Its capacity should match the parameters of a hydraulic cylinder to be used later. The piece of pipe should be welded at the ends with stopping plugs cut from sheet steel.
A window is cut into the tank for the filler. A lid is sawed out of a sheet of steel onto it. It and the tank itself to be drilled and threaded in the holes. Then the gasket is cut out, which will hermetically screw the cover.
The tank is shined through in two places. High pressure hose fittings are screwed into the holes. An oil filter is screwed onto one of them inside the tank.
Next pump is connected to a nozzle on the tank. To increase mounting rigidity it is necessary to weld a crosspiece between the tank and the transition pipe between the pump and the starter.
Using adapters and high-pressure hoses, you must connect the second fitting in the tank to the hydraulic pump through the valve.
The latter, in turn, should be connected to the hydraulic cylinder.
Thus, after filling up the tank with oil and connecting the starter to the batteries, it is possible to operate the hydraulic cylinder. To do this, start the engine, then use the lever of the hydraulic valve to supply oil to the cylinder. As a result, the hydraulic actuator can be used as a power unit in various designs. This could be a bending machine, a press or a hoist.
How to make a high-pressure pump
There are threads in the end of the rod, and you can turn out adapter bits for different needs. bending metal, pressing, drawing, etc. Double-acting cylinder. Working pressure, not more, MPa: 10 Working diameter of the cylinder, mm: 80 Stem diameter, mm: 28 Total stroke of rod, mm: Weight, not more, kg: 13,5. Although initially the tubes are sold flared
Although suitable for something else! I am attaching the drawing of the nozzle. But it’s a true 12.5 ton force, not the Chinese 25, 30, etc. By the way the press originally wanted to buy, but looked at all this crap that is sold for a lot of money from 15 to 40 thousand.
Generally speaking, it is a health hazard. If the thing blows up in your face, it will not be good for your health.
Variants of use in home conditions
The use of a hydraulic press in a garage or home workshop is quite common. This compact press is ideal for use in car repairs and other applications.
In particular, with such a compact equipment you can perform pressing out of bearings or silent blocks, as well as press new parts in their place. In addition to automotive repair, the hydraulic press can be used for bending metal parts, creating the required pressure when gluing surfaces, briquetting waste, for squeezing oil and liquids. Factory equipment for this purpose (even a manual hydraulic press) costs a lot of money and is not available to everyone. Meanwhile, you can make such a press with your own hands, spending money only on the purchase of the necessary materials.
Using the press as a juicer
Remarkably, the design of the home-made hydraulic press can be immediately adapted to solve a particular problem with a particular part or workpiece. The handmade press will not take much space, for its placement will be enough to allocate a little space in the workshop or garage. Detailed instructions on how to make a hydraulic press are given below. At the end of the article there is also a video on this topic.
WHAT KINDS OF MANUAL HYDRAULIC PUMPS ARE THERE
The simplest of all designs is a hydraulic hand pump, which is actuated by the efforts of the hand. Thanks to such actions can be used:
Note. This is not the complete list of devices that are powered by handheld hydraulic pumps.
In the case of acquiring a hydraulic pump with manual drive, you should consider some indicators:
- External dimensions and weight.
- The viscosity level of the working fluid.
- Handle forces.
- The pressure of the stages (first and second).
- Tank capacity.
- The cost of goods.
Tip. Before purchasing equipment, it is recommended to get acquainted with the operational properties and technical characteristics.
The tool is selected depending on the power of the entire system and equipment in general, to which the hydraulic pump with manual drive is connected.
Hand-operated hydraulic pump with your own hands (hydraulic handbrake)
The basis of the manual hydraulic pump includes a support, where the tank for the oil fluid and the body with a handle are located. This kit includes a pressure gauge to control all readings. So:
- There are designs that are supplemented with a special foot drive, which facilitates all stages of work.
- Oil tank made of plastic.
- The internal parts are made of brass.
Rugged hose connection for the hand pump and hydraulic system.
HYDRAULIC HAND PUMP: ADVANTAGES AND DISADVANTAGES
Advantages and disadvantages of hydraulic hand pumps
- Requires no electrical outlet. Can be used anywhere.
- The pump works perfectly without diesel and pneumatics.
- Requires simple human power to operate.
If small amounts of work are foreseen, then manual hydraulic pumps, this is the best option. But there is a disadvantage: not suitable for large volumes due to low capacity.
MANUAL HYDRAULIC PUMP: TYPES AND CHARACTERISTICS
The HP series includes single-stage and two-stage models with oil reservoir, ready to use. Working pressure of all models up to 700 bar.
Note. This series includes hydraulic hand pumps, suitable for use with hydraulic tools and single-acting cylinders.
Two-stage HP models are used when a small independent high-pressure source is needed:

The manufacturing process
When the drawing of your future hydraulic press is ready, and all necessary materials, tools, equipment and accessories are available, proceed directly to the manufacturing. The first thing to do is to cut all the metal, following the dimensions given in the drawing.
One of the variants of the drawing for making the press
Now you should make the base of the press, which is welded together prepared a square tube, and on the rectangle formed from them a steel plate is welded. Then the sides and the top of the frame are welded together, making sure that the resulting U-shaped structure is level and has strictly right angles in the joints. Now the resulting structure should be welded to the base, and you can consider that the frame for your hydraulic press is ready.
The next element you will need to make for the press is the moving platform. It can be made using a channel, square or rectangular tube. In the central part of the platform a piece of pipe is welded, which will serve as a socket for the head of the jack rod. To make the guides for the working platform, you will need two steel strips, whose length should match the width of the press frame on its outer contour.
Variant of press construction with movable lower platform, which is fixed by bolts
The bars are bolted to the sides of the mobile platform, first engaging it inside the frame. According to the same scheme, a removable support is also made, but in its guide strips holes are drilled in front of the frame pillars for fixation at the right height. Completes the process of making a hydraulic press with their own hands, installing the draw springs and the jack itself. Another good thing about this hydraulic press is that you can always take the jack out of it (for example, if you need to use it to repair the car).
The appearance of the finished homemade press
One of the rather economical variations of the hydraulic press, made by your own hands in your garage using simple devices, welding, a jack and channels.
Types, properties and characteristics of the hydraulic jack
The modern market of components and spare parts for cars is characterized by a variety of hydraulic elevators. Popular types of devices include the following:
Bottle lifters have a simple design, allowing it to be used in many applications.
They are used to lift loads, whose weight ranges from 2 to 100 tons, and most of the bottle models work in the vertical plane. To put the mechanism into action, you need to prepare a support platform with a large plane, and with the help of a double rod design, the height of lifting is regulated.

The bottle jack in action
Rack and pinion jacks, which function in the horizontal plane, have a wheeled cart, which should be placed under the object to be lifted. With the progressive movements of the lever to pump up the pressure for the output of the rod, as a result of which the arranged tumbler comes into action. In order to lower the load, it is necessary to unscrew the lever back, but it is strictly forbidden to hurry when doing this, because the car could fall sharply.
If there is no possibility to use a stationary model, you can use a hooking jack, which allows you to hook and raise the car to the desired height. But the distance under the load must be at least 15 mm, some towing constructions are equipped with a step regulation.
As for the lozenge elevators, they consist of four frame elements that are connected to each other by hinges. The process of lifting the vehicle is carried out by changing the angles between the elements of the carcass.
Hybrid jacks are so named because their design combines the bottle jack and the car jack type. Elevators with two lifting platforms are used in car repair shops where vehicles of different brands, classes and modifications are serviced.
One of the lifting platforms of the hybrid should be lifted not more than 375 mm above floor level, the second one. up to 700 mm. The drive is represented by a foot pedal or lever, and in order to facilitate the operation of hybrid models, it is recommended to use an electromechanical drive.
