Although there are many reasons why the motor is burnt out, the proper use of the pump is one of the important reasons.
When using the pump, after the power is turned on, carefully observe the operation of the pump, the water should be continuous and uniform, the pump without vibration and noise before use. If suddenly shut down during operation, immediately disconnect the power and check the cause. Pump start time interval between two should be all the water pump back to the limit. If you start too early, the motor will be burned due to excessive resistance and water hammer in the water pipe. In addition, if the pump installed in the well, pay attention to the pump flow should be consistent with the normal well water, otherwise it will cause the empty machine running, burning motor.
In order to ensure the normal operation of the pump, it should be checked before use again. 1, with a multimeter to check whether the pump motor winding circuit. Insulation can be used for 500 V megohmmeter measurements, insulation resistance is less than 0.5 megohm, the pump can not be used. 2, remove the filter, rotate the pump shaft is flexible, if not flexible, should be adjusted before use. 3, gate fuse capacity selection is appropriate, do not use other wires instead of fuses. 4, turn on the power, check the impeller operation is normal (power on time not allowed more than 3 to 5 seconds, otherwise easy to burn the motor).

The so-called Pharmaceutical Intermediates are actually some chemical raw materials or chemical products used in the process of drug synthesis. This kind of chemical product does not require a pharmaceutical production license and can be produced in an ordinary chemical plant. As long as it reaches a certain level, it can be used for the synthesis of pharmaceuticals.
Our country needs more than 2,000 kinds of raw materials and intermediates for chemical industry every year, and the demand is over 2.5 million tons. After more than 30 years of development, the chemical raw materials and intermediates required for the country's pharmaceutical production can basically be matched, and only a small part of it needs to be imported. Moreover, due to my country's abundant resources and low raw material prices, many intermediates have been exported in large quantities.
On the one hand, product updates in this field are fast. Generally, after a product has been on the market for 3 to 5 years, its profit margin will drop significantly. This forces companies to continuously develop new products or continuously improve production processes in order to maintain a high production profit; on the other hand, due to the production profit of pharmaceutical intermediates Higher than chemical products, the production process of the two is basically the same, so more and more small chemical companies have joined the ranks of producing pharmaceutical intermediates.
