Circulating pump vacuum pump is a kind of equipment often used in supporting equipment. Failure often affects the smooth operation of collective production. If you can understand the true principle of the pump, you can judge the cause of the failure and repair it yourself. Avoid the time to find experts, can be rapid production.

1. The circulating vacuum pump has been used for more than a year, but now the cooling speed seems to be getting slower and slower, which is more obvious when the temperature is higher?

A: water recycling is very simple, but regular maintenance work can not be ignored. There are many seemingly malfunctioning problems, which are caused by not doing regular maintenance. The electric power of the water cycle and the heat carried away by the refrigerant from the load need to be discharged from the radiator at the front ventilation hood. If the front ventilation hood is full of dust and willow cotton, it will hinder the heat emission, and the refrigeration effect will be greatly reduced. Generally speaking, the decrease of cooling capacity under normal use conditions is caused by poor ventilation and heat dissipation effect or high ambient temperature.

2. Water circulation used to be very normal, but now found that the noise is much bigger than before, what is the reason?

A: the daily maintenance of water circulation has been mentioned earlier, and this problem is also related to it. As we all know, there are a few impurities in the water. Even after the distilled water is added to the water tank, it is impossible to guarantee that there is no impurity at all. For the water cycle, the temperature is generally set at 20 ℃, which is especially suitable for the growth and reproduction of microorganisms. After a long time, these microorganisms will block the filter of the water path, causing backwater is not smooth, and the pump will have greater noise. Sometimes these microorganisms attach to the surface of the heat exchanger, resulting in poor heat transfer effect and cooling capacity. Therefore, it is necessary to do a good job in the daily maintenance of circulating water vacuum pump in strict accordance with the requirements of the manual, regularly clean the inner tank, stop using for a long time, and keep the tank dry.

3. There seems to be water leakage in the water circulation. Sometimes there are a few drops on the ground. Is there any leakage on the waterway?

A: Generally speaking, there will be no leakage in the waterway during normal use. When the ambient temperature is relatively high and the relative humidity in the air is too high, dew is easy to condense at the water pump, water pipe joint and external water pipe in the water circulation water path. After accumulating more dew will drip to the ground, so there is no need to worry about the water leakage. If you care about this, turn on the air conditioner to reduce the room temperature or dehumidification can avoid dew.
