Japan Yamada YAMADA company launched a printing ink supply pump. The pump has the following characteristics: 1, a stable mechanical supply conversion system; 2, a great elimination of exhaust noise, conversion of metal noise; 3, through the piston rod lubrication constitutes a smooth spray system; 4, improved Air flow structure, not easy to freeze; 5, the pump mechanism emphasis on quantitative; 6, compact design; 7, induction plate easy to insert the ink tube, and easy to replace, the outer diameter of the variable sealing system. The following system has been patented pump: induction plate structure is inserted into the barrel can be effectively sealed within the wall. In the replacement of ink barrel, the outer diameter of the envelope will be reduced, can be successfully removed. In the exchange of ink, the ink will not fly, will not be dirty around, will not waste ink.
Gate Valves are called "full-flow" valves; there's a direct unobstructed path for flow right through the middle of the valve. A wedge-shaped brass gate is lowered into a machined slot to close the valve. They should either be completely open or completely closed. Water flowing through a partially open gate valve wears away the metal and causes the valve to fail over time.
