Zhengzhou Du Fu Instrument Factory is located in the hometown of Du Fu, the famous city of Gongyuan in the Central Plains. Our main products are: circulating water vacuum pump, hydrothermal synthesis reactor, low temperature coolant circulation pump, glass reactor, rotary evaporator, low temperature constant temperature reaction bath, fast dissolved oxygen tester, double glass reactor, rotary evaporator Glassware airflow dryer, electric, magnetic heating stirrer, constant temperature water bath, electric centrifuge, electric heating sleeve and other products are carried out by universities, research institutes, pharmaceutical and chemical engineering, bioengineering, petroleum exploration and other laboratories. The ideal equipment for research and analysis, the products have the domestic level of ling first, and the leading products have passed ISO9002 quality certification.
The flow regulation of the circulating water vacuum pump is regulated by two "8" shaped rotors. The principle is: two "8" shaped rotors (you can see the position change on the dial), the axial transformation through the adjustable shaft and the sliding shaft, this movement is transformed into an eccentric through the chute on the sliding shaft The radial displacement, pushing the piston through the connecting rod, achieves the purpose of flow regulation due to the change of the stroke of the piston. How to adjust the flow and pneumatic diaphragm vacuum pump maintenance of the pneumatic diaphragm vacuum pump.
The maintenance of the circulating water vacuum pump is different from other types of pumps. The main points are as follows:
1. Check the pump valve should pay attention to whether the seal ring is aging and deformation, whether the spring elastic force is seriously reduced, whether the valve port and the valve core have any defects such as wear and corrosion. When installing, the valve end surface should be flush with the pump body flange surface and cannot be recessed;
2. When the diaphragm is replaced, the disassembly and assembly pump head should be lifted in advance to prevent falling damage;
3. When the adjustment mechanism is disassembled, the stroke length position (stroke length is 5mm) should be calibrated. Remove the scale holder and slide the scale ring into the calibration position. The measured stroke length should be exactly the same as the scale.
4. When disassembling the piston, use a special pointed tool to remove the packing ring from its slot, taking care not to damage the ring groove;
5. The worm and worm gear should be inspected, the teeth should be intact, there should be no cracks or broken teeth, and the meshing contact should be checked during installation.
