After a long period of use, the device may cause certain failures. The high and low temperature coolant circulation pump needs to be maintained after a long period of operation. Then, what aspects should be paid attention to during the operation of the high and low temperature coolant circulation pump.
To ensure that the high and low temperature coolant circulation pump can operate normally after starting, it must be ensured that the condenser has good heat dissipation, otherwise it will stop due to the action of the high temperature protection device of the high and low temperature coolant circulation pump unit due to the excessively high condensation temperature and corresponding condensing pressure. It can even cause malfunctions. During the operation of the high and low temperature coolant circulation pump unit, the parameter recording work should be done in time and correctly. If there is an alarm shutdown during the operation of the high and low temperature coolant circulation pump unit, the relevant personnel should be notified in time to check the unit. If the failure cannot be eliminated, you can contact the factory directly.
It is strictly forbidden to short-circuit the water flow switch during the operation of the high and low temperature coolant circulation pump unit, so as not to freeze the water pipe. The high and low temperature coolant circulation pump machine room should be equipped with corresponding safety equipment and maintenance testing tools, such as pressure gauges and thermometers. The tools should be Store in a fixed location. Do not turn off the main power supply after the high and low temperature coolant circulation pump unit is shut down. If the unit is in a long-term shutdown state, all the water accumulated in the wind part of the cold water system should be drained to prevent rust. The end cap of the water chamber should be sealed. When the high and low temperature coolant circulation pump unit is shut down for a long time, it should be well maintained.
It is recommended to replace the lubricating oil every four years or when the quality of the lubricating oil deteriorates and the impurities and moisture in the oil increase, and clean the condenser at least once a year. It is recommended to clean the condenser before use every year and once in hot summer days.
When controlling the temperature of the high and low temperature coolant circulation pump, it is necessary to quickly compensate for the heat absorption and release in the chemical reaction. When selecting the appropriate temperature control system, it is necessary to comprehensively consider various conditions and influencing factors. Most applications of temperature control will involve stainless steel, glass reactors and other reactors. Stainless steel reactors are more robust and durable, while glass reactors allow users to observe the reaction process in the reactor body. For glass reactors, in order to Application security requires many considerations. In order to control the temperature of the reaction kettle, the temperature control system continuously drives the heat transfer oil into the jacket of the reaction kettle through the circulation pump. The temperature inside the reaction kettle changes abruptly, which will be achieved by rapid heating and cooling of the temperature control equipment. Compensation is performed to achieve dynamic cooling and heating control, and the heat transfer oil is heated and cooled in the temperature control equipment.
The matters needing attention in the use of high and low temperature coolant circulation pumps are as shown above, and users should pay attention to maintenance during use, so that the high and low temperature coolant circulation pumps are better used.
