The hydraulic oil press has a large area, consumes less power, and has a good quality of oil cake. It is widely used in rural areas in China. It is used to squeeze oils such as peanuts, soybeans, cottonseeds, and rapeseed oil for food. Now its use of knowledge is introduced as follows: 1, inspection and debugging 1.1 Before the oil pump test, first add clean mechanical or vegetable oil in the oil tank, press the handle up and down to see if the piston of the oil press machine rises. If the piston does not rise or the handle is effortless when pressed, check the valves of the tank and remove air from the lines. 1.2 Perform pressure test of the whole machine. The pressure used in the test is 1.25 times the working pressure. Check that the piston extends to the maximum working stroke. Regulate for 15 minutes. The drop value of the pressure gauge shall not exceed 4% of the test pressure; There should be no leakage phenomenon; after all the pressure is removed, the pressure gauge pointer will return to “0†position, the part shall be not damaged, the tie rod shall not be significantly deformed, and the moving parts shall not be stuck. 1.3 Reliability test of the safety valve, adjust the safety valve to working pressure (upper left + 5, lower left + 1 MPa), continuous test 5 times, needle valve opening and closing sensitive, pressure gauge reading should not be low after each jump Rated working pressure. 2, using the operation 2.1 According to different oil, grasp the billet into the pressing temperature and moisture content. 2.2 When pressing, lower the lower top plate to the lowest position, loosen the movable tie bar nut, pull out the two movable pin shafts, and turn the movable pull bar on one side. After the cakes are loaded into the squeezing clams, the movable levers are turned back to their original positions, pre-pressed until the oil is finished and freshly stored, the pistons are returned, and the rest of the cakes are loaded into the formal squeezing (generally the hydraulic oil press can hold the cake 20 Piece). 2.3 When pressing the handle, pressure should be light pressure and pressure must be applied evenly. Do not use excessive force. Otherwise, accidents may occur easily. 2.4 Press oils with high oil content (such as peanut kernels and rapeseed). Use the low-pressure pump to work for the first time and use the high-pressure pump to work after the oil is discharged. 2.5 If it is found that the pointer of the pressure gauge is not back to zero during work, it shall be verified, repaired or replaced in time. 2.6 When the oil return valve is opened, the oil will flow back to the tank automatically and the piston will drop automatically and it can be unloaded. 3. Maintenance and repair 3.1 The pressure oil in the oil pump should be filtered for water-saving irrigation. The concentration should not be too large. It is best to use rapeseed oil, soybean oil and peanut oil, etc. The use of gasoline, kerosene and other flammable oils is prohibited. 3.2 The fuel tank should be kept clean. Clean the fuel tank every 3 months or so, replace the oil, or remove the oil from the tank before use. Impurities in the oil will cause the oil pump to wear and cause blockage in the oil circuit, affecting the operation of the oil press.
Tattoo flash are prepared tattoo designs which are intended for use in rapid tattooing. Most visitors to tattoo shops have seen tattoo flash, as they are typically displayed in the walls and in portfolios to give customers an idea of the kind of work they can receive. Tattoo flash encompasses a wide range of styles and designs, and it can come from a variety of sources.
Originally, tattoo flash were designed by the artist, who would display flash so that customers could pick a tattoo they wanted. Artists would also modify flash or create custom pieces on request. Over time, artists started trading flash with each other, and also also selling tattooflash, disseminating styles and designs across a broad community. Ultimately, companies started hiring tattoo flash designers, who produce a high volume of pieces for commercial sale on individual sheets or in books of collected tattoo flash.
Some people look down upon tattoo flash, arguing that while it's fine to use flash for inspiration, tattoos really ought to be custom designed, to create a unique and original piece. Copying from flash can also have complex copyright implications; for example, a client who prints out a piece from the Internet and asks to get it as a tattoo might potentially be violating copyright laws, unless he or she has been given explicit consent to use the work.
