Description
Technical Field
[0001] The invention relates to the technical field of plunger pump parts processing, in particular to a novel pump bladder grinding machine. Background Art
[0002] At present, the plunger pump relies on the reciprocating motion of the plunger in the cylinder body to change the volume of the sealed working chamber, thereby realizing the process of oil suction and oil pressure. The oil pressed out by the plunger enters and discharges through the waist-shaped holes on the oil distribution plate. Before mass production of a plunger pump, it is necessary to conduct repeated tests many times until the plunger pump reaches the expected output power. Each time the test fails to achieve the expected output power, the plunger pump needs to be disassembled to observe the curved contact area between the cylinder body and the oil distribution plate and whether there are scratches. Because most cylinder bodies are made of steel contact surface clad with copper alloy, and the oil distribution plate is made of steel, the hardness of the oil distribution plate is greater than the hardness of the cylinder body. Therefore, the scratches on the oil distribution plate of the cylinder body are not dents, but marks left by the rotation and friction of the material of the cylinder body itself on the oil distribution plate. The output power of the plunger pump is mostly affected by the contact accuracy between the cylinder body and the oil distribution plate. The technicians can judge the matching degree between the oil distribution plate and the cylinder body by observing the location of the contact mark. In addition, before reassembling the oil distribution plate on the plunger pump, the oil distribution plate needs to be ground. After the scratches are removed and the thickness of the oil distribution plate is reduced to a certain extent, it is reassembled on the plunger pump to continue the test until the plunger pump reaches the expected output power. When the expected output power is reached, the thickness of the oil distribution plate is detected at this time, and the oil distribution plate is mass-produced with this thickness to complete the batch assembly of the plunger pump. When grinding the oil distribution plate, it is batch-ground on a grinder. However, if a single oil distribution plate needs to be ground during the test, it needs to be ground manually. Manual grinding is inefficient and it is easy to get tired after grinding for a long time, which reduces the grinding accuracy. Therefore, an electric grinding device is needed to improve efficiency.
