PE-M1730 Fourier transform infrared spectroscopy reuse pen
Including the Epson-I \The use of pen plotter for the special one-time supplies from the U.S. company specializing in P-E. In recent years,[link widoczny dla zalogowanych], due to the upgrading of equipment, this pen has been unable to buy the domestic market is no substitute products. The special pen ink filling shall be done using the original waste, but other parts of the intact, providing the possibility for reuse. The analysis of the structure and principles of the drawing pen, and multiple tests, and finally groped a realization by re-drawing pen ink filling method of recycling. This method is simple, low cost, space pen can be different colors of ink filling and re-use, not only to ensure the normal operation of the instrument, but also to solve the original problem of a single color pen. (1) the structure and working principle of the pen cartridge parts than a little metal inclusions, the drawing pen for the plastic products, a good seal between the parts, no opening of the office. Pen structure shown in Figure l. Ink leaking from the cartridge with the ink of the steady decline in cavity pressure decreases, this time, and gas from the opening along a pen into the swing by the gas b c, d into the ink chamber, and external pressure balance,[link widoczny dla zalogowanych], so that a smooth ink leaking. Figure l Schematic drawing pen '1,[link widoczny dla zalogowanych], cover 2, the ink Mu 3, 4 pneumatic swing,[link widoczny dla zalogowanych], pen Su '5,[link widoczny dla zalogowanych], pen metal shell gas rh_. r. d,} Ir (2) document the methods, materials and specifications re-use: kerosene lamp, fine wire (<0.8mm), rubber, syringes soft soap. How: The thin wire on top of the pen after burning (1) hot out of two small holes, with the rubber to the bottom of the seal. Slowly from a small hole with a syringe injected the ink color selected, with another syringe to the corresponding rate from the other holes to the ink out of gas filled. The top two holes and then sealed with soap, gently remove the rubber seal, place the moment you can use. (3) Note seal: Select a small dog with a rubber seal to fit, sealing to be strict, otherwise the ink will be under gravity into the gas line, causing leaks. In as much as possible when removing the rubber stable to avoid vibration caused by increased pressure on the ink into the gas line. Top hole: the top hole is small and can accommodate injection needle can be. Its role is to help seal and removing the gas. Note the ink, the exhaust rate should be appropriate. Note halo of water too quickly, the pressure increased, the ink will be into the popular road. (4) Summary of the experiment, using the method re-use pen the same effect as the original pen, drawing a considerable amount. The age of the drawing pen 9o international market price of $ 9.2 each, according to a dosage of 200 instruments per year calculated using the original document to be spending $ 1,840, equivalent to 14,720 yuan (1: , while the cost of re-use only the ink costs, expenses less than RMB 50, savings effect is obvious. Repeat this method on the original document using the drawing pen almost no damage, runs out of ink, wash away the soap sealed holes, repeat the above operation, you can achieve the purpose of repeated use.
