As a common pump, the mini metering pump is likely to be damaged during use. When it is damaged, the accessories of mini metering pumps need to be replaced. At this time, our technicians need to disassemble the mini metering pump. So what are the disassembly steps? The editor of Guangzhou Ascend Precision Machinery Co.,Ltd. will give you an introduction.
Disassembly of the hydraulic cylinder parts of the mini metering pump:
1. Before proceeding with the disassembly steps of the mini metering pump, it is necessary to clarify that the internal structures of the pumps produced by different manufacturers are different. There may be slight differences in the details of the disassembly, but the overall steps are similar.
If there is anything unclear, it is recommended to ask the micro The manufacturer of the metering pump.
2. Clean the parts of the mini metering pump first, and check whether there are damaged parts, and then disassemble the pump after ensuring the integrity of the parts. Remove the pipeline and accessories connected to the one-way valve of the mini metering pump;
3. Remove the pump head of the mini metering pump, unscrew the diaphragm (it is better to communicate with the manufacturer at this time), and then remove the hydraulic cylinder head connection from the transmission box;
4. Remove all parts of the tappet assembly in the following order: A. Remove the spring seat of the mini metering pump; take out the spring seat, spring, and tappet of the outsourcing parts in turn; remove the components that need to be replaced if the composite bearing is worn. Next, replace it with the same model. B. Remove the suction and discharge valve (flange) of the outsourcing component; sequentially remove the valve sleeve, limit piece, valve seat, and valve ball of the mini metering pump.
Disassembly of the transmission box of the mini metering pump:
1. Drain the lubricating oil in the box of the mini metering pump.
2. Remove the motor and motor seat of the mini metering pump, pull out the coupling, bearing pressure plate, etc., and pull out the worm assembly.
3. Remove the regulator assembly of the mini metering pump, and then remove the adjusting handwheel and adjusting ejector rod from the assembly.
4. Remove the cover at both ends of the main shaft to take out the worm gear, eccentric wheel and main shaft from the box.
The assembly is carried out in the reverse order of the disassembly. But note: After assembling the components of the mini metering pump, the assembly gap should be checked. After the assembly is complete, it should rotate freely without jamming.
1. When assembling the sliding sleeve adjuster seat, you must turn the adjusting top rod to the dead point, and at the same time turn the adjusting hand wheel to the scale of 20, and fine-tune the hand wheel to make the adjusting rod match the chute.
2. Adjust the tightness of the packing compression nut properly, and turn the miniature Li Jianbo's coupling for trial rotation. It should rotate freely without jamming.
Mastering the disassembly steps of the mini metering pump can facilitate regular maintenance of the pump and replacement of various mini metering pump accessories. The disassembly steps is not complicated. As a precision mechanical pump, you should keep your attention when we disassemble the mini metering pump, and follow the correct steps to disassemble it in detail to avoid the harm caused by the leakage of the medium. Manufacturers seek professional technical support.
