Chemical pump use precautions

The operator should remember that protecting the chemical pump and its equipment is their responsibility. The various factors that affect the operation of the pump should always be checked and the life of the pump can be significantly reduced due to operator carelessness. 1. In order for the pump to operate normally and extend its service life, routine inspection and maintenance should be done to make it a system. The emergence of failure will have an impact on the production, so the daily inspection is indispensable, must not be ignored. 2. Something went wrong during pump operation and it looks like the equipment still seems to be running. In most cases, however, there has been a warning of an accident, and early detection of anomalous precursors is an important factor in preventing an accident. To detect anomalies early, we need to know the normal operation of the situation, and inspection, maintenance and so detailed records, in addition to the basic information on the inspection failure is indispensable, but also contribute to routine maintenance and early detection of anomalies . 3. In recent years, pump operating environment has greatly improved, but there are still a considerable number of pumps are operating in poor conditions, both good and bad operating environment should be frequently rubbed to improve the environment and keep the pump and its Auxiliary equipment cleaning, especially in the poor operating environment pump should pay attention. 4. Pump in normal operation, even if the degree of automation does not require monitoring of the pump, at least once or twice each class to be checked, as mentioned earlier this is one of the important work of early detection of anomalies, in addition, according to Need to do regular roving inspection. The contents of routine inspection table, for some pump according to the manual appropriate trade-offs. 5. In the daily inspection, in addition to fully operational control, test instruments, but also to play the role of subjective and active physicians, like the doctor's diagnosis, "look, smell, ask, cut" that check the pump anomalies. "Look" is to look at each instrument to indicate the pressure, flow, temperature, current, voltage is normal, whether the deformation of the pump parts, discoloration, sample change and leakage, with or without blockage; "smell" is to use Smell, smell abnormal odor, liquid hydrocarbons, gasoline, benzene and other leaks smells, equipment paint, rubber insulation, such as baking scorching paste flavor; "ask" is to listen to hear the sound of the rotating part, with or without Abnormal sound, such as water hammer sound, friction noise, percussion sound, vortex sound, broken sound, etc .; "cut" is touch, touch with or without overheating, vibration and so on. Only in this way can operators play a role. With the help of various test instruments and instruments, the daily inspection can be done well and anomalies can be detected early enough to take preventive measures.
