The goal of the grinding and polishing step is to prepare the final polished sample without deformation and suitable for analysis. This can be done in a number of ways depending on the overall objectives of the laboratory. Whether the lab is looking for the fastest overall process, the best surface finish or the versatility to prepare many different materials, Buehler can provide the solution for your grinding and polishing needs.

YYZ30 type oxygen filling pump Introduction: YYZ30 type oxygen filling pump used to boost the oxygen in the gas source bottle to another cylinder, so that the oxygen in the cylinder to achieve the required pressure oxygen filling equipment, is also suitable for the Oxygen, nitrogen, carbon dioxide and other gases from the gas source bottle and filled into the bottle to be filled. YYZ30-type oxygen filling pump works: YYZ30-type oxygen filling pump works by the piston on the compressor constantly reciprocating motion to complete the filling of the oxygen bottle filling work in the first and second cylinder are equipped with suction at both ends Valve, exhaust valve, its role is to control the direction of airflow, suction, exhaust valve of the quality of the inflatable efficiency has a more significant impact. When the primary piston moves downward, the gas in the primary cylinder expands and the pressure decreases. When the pressure in the primary cylinder is lower than the pressure of the gas in the large oxygen cylinder, the primary suction valve opens automatically. The gas When the primary piston moves upwards, the gas in the cylinder is compressed and the pressure rises. When the pressure is higher than the gas pressure in the secondary cylinder, the exhaust valve of the primary cylinder and the exhaust valve of the secondary cylinder When the piston in the secondary cylinder moves upwards, the gas in the secondary cylinder is compressed and the pressure rises. When the pressure of the secondary cylinder is higher than that of the secondary cylinder, When the gas pressure in the gas bottle is inflated, the two-way exhaust valve passes the one-way valve on the gas-water separator and inflates the gas into the inflated bottle to complete the inflation. YYZ30 oxygen filling pump Specifications: Maximum exhaust pressure: 30MPa Exhaust gas intake conditions: 3L / min Compressor Series: 2 maximum compression ratio; 8/9 Number of crankshaft rotation: 440rmp
