Excavator filter if the differential pressure is too high for a long time, can cause the center pipe crushed, excavator filter deformation, and, in turn, impact work, and if you use time is too long, the service life of the excavator filter and quality will be affected, has been in a state of differential pressure is too high, can cause abnormal filtering effect.

In recent years, a few small manufacturers using small sewing machine for processing equipment, and process using inferior line as raw material, the setup, the level of processing is also far behind. Make the filter bag in the use of time is not long appears the phenomenon such as line, fissure, off bottom.

2. Excavator filter in the use of the scope of the above should have a certain way and method of reasonable maintenance mode can increase the using time of the filter and the fixed number of year

When the filter in the system work after a period of time, the hydraulic oil filter filter pollution has intercepted a certain amount of impurities, then pressure increases, the flow will decrease gradually, transmission device will remind alarm, then need to clear in time the impurities inside the filter, clean the filter.

In the process of cleaning filter, we must pay attention to the hydraulic oil filter deformation or damage is not allowed. Otherwise, cannot be used again, lest affect filtration efficiency, so as to bring the entire system damage. Right to choose suitable for the corresponding temperature of dust filter is the key. If the temperature is too high, chooses the dust bag to beyond normal use of temperature, light, shorten the service life of filter pocket, the serious will be destroyed in a short time. Therefore, when choosing filter bag must compute the determination of dust collector inlet temperature, in chooses the corresponding filter
