Dear masters, the gears of the twin-screw pump keep breaking. Can the parallelism of the pump shaft be adjusted?
Thread Content
The twin-screw pumps produced by Tianjin Pump Industry are used with wax oil as the medium, and the gears in these pumps often break
Is there any grinding or binding between the screws? Are there any hard particles in the material? Has it been started with high torque?
Broken teeth indicate that the gear pair is overloaded. The reasons can be investigated using the following two suggestions: one is that difficult rotation of the driven screw due to shaft binding leads to overload of the gear pair and subsequent tooth breakage; the other is that the gear tooth profile chosen is too small, resulting in an insufficient capacity to handle the operating torque.
Of course, this first requires ruling out the possibility of proper installation in order to find the cause
Is it also related to the mass of the gear itself? Teeth had never broken before
First, measure the rotor meshing clearance and reduce it by half. Then install the two gears; the gear meshing clearance should be 12 microns. At the point where the two gears meet, insert a 5-micron stainless steel strip on each side. Tighten the bolts securing the driven shaft gear sleeve to lock the gears, allowing for easy rotation of the shaft
Of course, the quality of the gears certainly has an impact; for example, excessive quenching can result in a lack of resistance to impacts. By \"tooth damage,\" do you mean deformation of the teeth or their fragmentation?
