Chemical Pump Use Precautions

  Chemical pumps have been used in various chemical processing fields for a long time.

  At present, the chemical types of pumps produced by DUBAO pump manufacturers are stainless steel chemical centrifugal pumps, PD type fluoroplastic chemical pumps, PT type fluoroplastic chemical pumps, MD chemical magnetic drive pumps, MDH chemical magnetic pumps, PD self-priming chemical transfer pump, DBM chemical metering pump，etc.

  So, what problems must be paid attention to when using chemical pumps on a daily basis? look down:

  1. To make the pump run usually and continuously and prolong its service life, You should do daily inspection and maintenance to make it a system. The occurrence of failure will affect production, so the daily review is indispensable and must not be ignored.

  2. There is some abnormal phenomenon in chemical pump operations, and it seems that the equipment is still running. For example, during positive displacement pumps, the moving parts have a temperature rise. Even if there is no problem with the indicators during production, You should stop it immediately for an inspection. There are signs of accidents in most cases, and early detection of abnormal movements is essential in preventing accidents. To detect abnormalities early, it is necessary to master the regular operation and make detailed inspections and maintenance records. This basic information is indispensable for checking faults and helpful for daily maintenance and early detection of abnormalities.

  3. In recent years, the operating environment of pumps has been dramatically improved. However, there are still many pumps that operate in poor environments. Whether the working environment is good or bad, frequent rubbing tests should be carried out to improve the environment and maintain the pump and its operating environment. The cleaning of auxiliary equipment, especially the pump operating in a poor background, should be paid more attention to.

  4. When the pump is in regular operation, even if it is a pump with a high degree of automation that does not require monitoring, You should do at least one or two inspections every shift, especially the high-risk pumps used in the chemical industry as peristaltic pumps. It is one of the critical tasks for the early detection of abnormal phenomena. In addition, chemical pumps require regular inspections. The daily inspection contents are shown in the table. You can appropriately select some pumps according to the instruction manual.

  5. In the daily inspection, in addition to fully operating the control and testing the instrument, it is also necessary to give full play to the subjective function of the human being and to check the abnormal phenomenon of the pump like the traditional Chinese medicine doctor's diagnosis of "look, smell, ask, and cut." "Looking" is to see, to see if the pressure, flow, temperature, current, and voltage indicated by the various instruments of the pumping system are expected and whether the different parts of the pump such as the mechanical seal are deformed, discolored, altered, whether there is leakage, whether there is a blockage, etc.; "Smell" is to use the sense of smell to smell whether there is any abnormal smell, the smell of leakage of liquid hydrocarbons, gasoline, benzene, etc., the smell of burnt insulation such as equipment paint and rubber, etc.; "Ask" is to listen, listen to the rotating part. Sound, whether there is any abnormal sound, such as water hammering, friction, impact, eddy current, breaking sound, etc.; "Cut" is to touch, touch the pump bearings for overheating, vibration, etc. Only by playing the operator's role in this way, with the help of various test instruments and instruments, can the daily inspection be done well; you can detect abnormal phenomena early and prevent problems before they occur.
