Doing a good job in the maintenance of imported vacuum pump equipment during the high temperature season in summer can reduce equipment maintenance costs and other abnormal expenses, lower operating costs, extend service life, and help improve enterprise efficiency. Wenzhou Youyijing Clean Equipment Technology Co., Ltd. has put forward targeted maintenance suggestions for the faults that are prone to occur in vacuum pump equipment in summer.

1. Mechanical equipment failures that are prone to occur in summer

1) Hydraulic system malfunction

Hydraulic systems often experience malfunctions such as pipe bursting, joint oil leakage, solenoid valve coil burnout, hydraulic valve jamming, and high noise in high-temperature environments; The system using an accumulator may cause damage to the accumulator due to high hydraulic oil temperature; Circuits that age in summer are more prone to cracking of the outer skin due to the thermal expansion and contraction of metals, resulting in short circuit faults; The electrical components in the control cabinet are also prone to malfunction during high temperature seasons, and key control components such as industrial computers may also experience malfunctions such as crashes, slow operation, and control failures.

2) Lubrication system malfunction

Long term operation of construction machinery at high temperatures will lead to poor lubrication system performance, oil deterioration, and wear of various transmission systems such as chassis. At the same time, it will also affect the appearance paint layer, braking system, clutch, throttle control system, and metal structure.

3) Engine malfunction

The impact of high temperature on the engine is mainly manifested in the rapid temperature rise of the engine. Under high external temperature conditions, it is easy for the engine to "boil over", causing the viscosity of the oil to decrease, resulting in mechanical failures such as cylinder pulling and tile burning, and also reducing the output power of the engine; The continuous high temperature has strict requirements for the permeability of the radiator, requiring the cooling system to continuously operate at high loads, reducing the lifespan of components such as fans and water pumps in the cooling system. The frequent use of air conditioning compressors and fans can also easily lead to their failure.

4) Other faults

In summer, the temperature is high and the humidity is high. If the vent hole of the battery is blocked, it will cause an explosion due to the increase in internal pressure; Working in high temperature environments during summer not only increases tire wear, but also causes tire blowouts due to increased internal air pressure; The transmission tape will become longer in summer, leading to transmission slippage, accelerated wear, and failure to adjust in a timely manner, such as tape breakage. Small cracks on the driver's cabin glass can expand or even burst in summer due to large temperature differences between the inside and outside or splashing water.
