| 摘要 |
<p>The invention relates to an apparatus for high pressure pumping or homogenizing liquids. The apparatus comprises a drive motor (1) with transmission mechanism and a pump section. The transmission mechanism comprises a belt train (6), a gearbox (7) and a crank mechanism which is housed in a crankcase (5). The pump section includes a pump block (8), valves and pistons (4) which are connected to the crank mechanism. The transmission mechanism caters for the conversion of the rotary movement of the drive motor (1) into the reciprocating movement of the pump pistons (4). The drive motor (1) is placed directly above the crankcase (5) and is surrounded on two sides by partitions (15, 16) which are interconnected by means of roof (17). The partitions (15, 16) form, together with the roof (17), an air channel such that the driving parts of the apparatus may be cooled in a simple and efficient manner. By means of various arrangements peripheral to the apparatus, the air may be led off or recycled after cooling and recovery of the heat.</p> |
