First, inspection and debugging 1. Before the oil pump test, first add clean mechanical oil or vegetable oil in the fuel tank, and press the handle up and down to see if the piston of the oil press rises. If the piston does not rise or the handle is not stressed when it is pressed, check the valves in the tank and remove the air from the line. Second, maintenance and repair 1. The pressure oil in the oil pump should be filtered. The concentration should not be too large. It is best to use rapeseed oil, soybean oil and peanut oil. It is forbidden to use gasoline, kerosene and other easy fuel materials.
Joint replacement is a medical treatment in which an artificial joint is used to replace a painful joint that has lost function.Our joint replacements are divided into Hip Artificial Prosthesis and Total Knee Artificial Prosthesis System.
The artificial femoral stems are also available in a plain type (which requires cement) and a coral type without cement. Indications for joint replacement include osteonecrosis, irreducible comminted fractures and dislocations, osteoarthropathy with pain and mobility disorders, rheumatoid arthritis with rigidity or difficulty in mobility, and bone tumors. Complications of replacement include loosening of the prosthesis, wear or fracture, deep infection, foreign body reaction, and soft tissue calcification that impedes movement. hip Replacements,Hip Implants,Hip Artificial Prosthesis,Artificial Prosthesis Jiangsu Aomed Ortho Medical Technology Co.,Ltd , https://www.medthofixation.com
2. Carry out the pressure test of the whole machine. The pressure used in the test is 1.25 times of the working pressure. Check that the piston extends to the maximum working stroke, and the voltage is reduced for 15 minutes. The drop of the pressure gauge reading shall not exceed 4% of the test pressure; All oil passages shall have no leakage; after all pressures are removed, the pressure gauge pointer shall return to the “0†position, the parts shall be free from damage, the tie rods shall not be significantly deformed, and the moving parts shall be free from sticking.
3. Carry out the reliability test on the safety valve, adjust the safety valve to the working pressure (+5 on the upper left, +1 on the lower left), and continuously test 5 times. The needle valve is sensitive to opening and closing. The pressure gauge reading should not be read after each jump valve. Below rated operating pressure.
2, the fuel tank should be kept clean, clean the fuel tank every 3 months or so, and replace the new oil, or take out the oil in the tank and filter it before use. Impurities in the oil can cause the oil pump to wear and cause oil blockage, which affects the operation of the oil press.
3. The coupling pin of the handle and the oil pump should be lubricated frequently to reduce wear.
4, the oil press should be installed indoors to avoid the open air wind and rain, causing rust and cooking oil pollution.
5. When parking for a long time, clean, oil, and cover the machine.
