China now has more than 90 branches in Japan, Chinese mainland, Taiwan,Australia, Southeast Asia, Europe and North America.
Founded by Yamada Chao in Osaka under the name of "Osaka Metal Industry Institute" on February 11,
1934 (Showa 9), it is now committed to the manufacturing of chemical industry, hydraulic machinery,
special machinery and air conditioning system. It is a comprehensive professional manufacturer of fluorine chemistry.
Installation and alignment
1, Ensure that the eccentricity of the drive shaft and pump shaft is no greater than 0.05 mm (TIR), and run the pump with no force acting perpendicularly on the pump shaft. Misalignment between the shaft centers will cause damage to bearings and oil seals, generate noise and vibration, and lead to pump accidents.
2,Avoid crosswise drive using a belt, chain or gears (it will cause noise generation or damage to the bearings).
3,The pump shaft can be installed vertically.
4, Restrict the clearance between the spigot joint of the flange and the hole to +0.01 to +0.05 mm in diameter.
5,Restrict the clearance between the key shaft and the coupling hole to +0.003 to +0.025 mm in diameter.
Operating principle of variable displacement piston pumps
1,When the shaft is rotated by an electric motor or an engine, the cylinder block is rotated on the valve plate surface while maintaining a slight clearance, and the pistons contained in the cylinder block reciprocate
following the swash plate. The volume of the oil chamber varies with the reciprocating movement of the pistons, sucking in and discharging oil.
2,During the suction process, an amount of oil corresponding to the piston stroke is drawn through the suction port of the endcap, passing through the valve plate port of the cylinder block, while the piston moves from the bottom dead point to the top dead point. In this process, the cleanliness of the oil should be ensured.
