What are consumables for vacuum pump

Consumables for vacuum pump | Common Troubleshooting of Vacuum Pumps

1. High temperature failure

Oil pump, the place where the pump body is high temperature needs to be checked: the water supply is not in good condition, the oil is dirty, the oil contains a lot of water, the oil friction in the pump, the oil circulation is not smooth, etc.

Dry pump, the place where the pump body is high temperature needs to be checked: the water supply is not in good condition (low water pressure, waterway blockage), there are many internal impurities and friction occurs, and the rotor is beat due to bearing damage, etc.

2. Noise

The noise problem is judged in the same way for the oil pump or the dry pump: confirm the source of the noise, whether the motor, gear end, exhaust pipe, whether the fixing of the pump body is shaking, the inside of the pump body, etc.

3. Can't work

There are two situations in which the pump cannot be operated: the pump body is stuck and the electrical failure occurs.

If the pump body is stuck, you can manually rotate the rotor or the main shaft by manually intervening on the rotor of the pump body to see if it can be rotated.

Electrical failure: abnormal power supply, or abnormal motor.

Consumables for vacuum pump the water quality and operating temperature of the circulating water are higher than a certain index, which are the main reasons for the scaling of the vacuum pump.

Reducing the hardness of the water and controlling the temperature of the circulating water can solve the scaling problem of the vacuum pump. During the operation of circulating cooling water, the return water temperature and return water volume of each pump should be tested to ensure normal water supply. The temperature of the water. In addition, the pump body drain valve of the circulating water vacuum pump can not only discharge the accumulated water in the pump normally, but also use the water pressure generated by the pump body during operation to regularly flush and water the dirt in the pump, which can prevent dirt on the one hand. Accumulation, on the other hand, can prevent the slag from turning into scale.

Consumables for vacuum pump Causes of scaling of circulating water vacuum pump:

1. Thermal decomposition: After the circulating water containing hardness components enters the vacuum pump, a water ring is formed in the pump body with the rotation of the pump to do work and heat, so that the bicarbonate dissolved in the water is gradually decomposed, and precipitates that are not easily soluble in water are formed. limescale.

   2. Solubility decrease: Negative solubility temperature coefficient Some salts decrease with the increase of circulating water temperature, so as to precipitate and form scaling.

  3. Mutual reaction: The salts with higher original solubility and other salts in the circulating water undergo a physical chemical reaction when the circulating water vacuum pump is running to generate insoluble substances, thereby forming scale.

  4. Evaporation and purification: The continuous work and heating of circulating water will inevitably produce evaporation and concentration. When the concentration of dissolved salts in the water continues to increase to saturation, precipitation will precipitate to form scale.
