Nowadays, in order to put the screw pump into production as soon as possible, many manufacturers often fail to meet the conditions of the pump, or the installation is not correct, and iron scraps, welding slag, etc. in the tubing are easy to damage the pump. . In fact, this way, not only can not improve the efficiency of production or save costs, but also may lead to damage to the screw pump, resulting in production delays, and may even cause accidents! Therefore, in the process of using the screw pump, we must read the instructions in detail or install the operation according to the manufacturer's instructions.
1. The suction and discharge pipe diameter of the pump shall not be less than the inlet and outlet diameters of the pump, and the inlet pipe shall be short and reduce unnecessary losses (such as elbows, etc.). The installation height of the pump shall ensure that the pump does not exceed the allowable suction when working. Vacuum height.
2. The pipeline should have a pipe rack, and the pump is not allowed to bear the load of the pipeline.
3. Inhalation before installation. The discharge pipeline should be cleaned, especially the welding slag of the suction pipeline must be completely removed to avoid seizing after entering the pump.
4. Connect the vacuum and pressure gauge at the inlet and outlet of the pump to observe the working condition of the pump.
5, the suction pipeline should be equipped with a filter , the filter screen is 40-80 mesh, the effective filtration area should be 20-30 times larger than the pump suction diameter.
6. If there are more than two pumps connected in parallel on the same pipeline, a check valve must be installed at the pump outlet to ensure the normal operation of the pump.
7. Place the unit on the foundation with the anchor bolts. After tightening, tighten the anchor bolts.
8. The location of the pump should be spacious and easy to overhaul.
9. After connecting the pipeline and determining the steering of the motor, the coupling is connected to the coupling. The coaxiality tolerance of the outer circumference of the coupling is 0.1mm, and the tolerance of the end surface of the two couplings is 2mm.
10. After the unit is operated for 3-4 hours, make the final inspection. If there is no bad phenomenon, the installation is considered qualified.
11. The inlet and outlet pipes connected to the pump must be cleaned, and impurities and welding slag must be kept inside the pipe.
The above points are pointed out that you must pay attention to the use process! The correct operation method can not only improve productivity, but also prolong the service life of the screw pump and reduce the occurrence of accidents! Please be sure to install the requirements when you use it!
