With the help of the principle of vacuuming, the suction truck is able to provide daily cleaning services. With the extension of the use time, such machines will also encounter breakdowns. So, how do we troubleshoot the problem of the vacuum pump of the suction truck in daily use?

First of all, we need to check whether the valve of the suction truck vacuum pump is open. If we don't open the outlet in the process of use, it may cause garbage to clog in the machine and cause the machine to malfunction.

The second part is to see if the mouth of the suction pipe of the suction truck and the position of the filter are blocked by foreign matter. If the suction nozzle is blocked by a foreign object, it may cause the machine not to operate normally and eventually cause an internal failure.

The third step is to check if there is a leak in the suction truck . Because the normal operation of such machines is mainly due to the vacuum state formed by its pressure to move, once the machine leaks, then the machine will not be able to run properly, the correct way is to find the location of damage, and timely maintenance.

The fourth step in the investigation work is on the speed of the suction truck. In order to be able to suck items, the rotational speed of the machine must meet certain requirements, otherwise it will affect its degree of vacuum and may cause malfunctions. Under normal circumstances, the normal suction truck vacuum pump is 1500 rpm.

During the investigation, we must avoid the fact that the machine does a vacant movement of the vacuum pump for a long time, which will cause its temperature to be too high, which may burn out the sliding plate of the vacuum pump and ultimately affect its life.

The suction pump vacuum pump is the main engine for the operation of the machine, so its quality and failure problems are the main areas that need to be solved. While safeguarding quality, we also need to regularly troubleshoot its failures. This will not only ensure the operation of the machine, but also protect the life of the machine.


ZXZ Automotive Bearings have good quality and long life, they are performance design projects summary.

Different kinds of auto bearings are customized to meet the various working conditions, and all of them need good quality and long life:


1. Alternator bearing:inner ring rotation with high sealing performance, can bear high speed rotation.high & low temperature environment.low starting torque and long life.

2. Tensioner pulley bearing:outer ring rotation with low load, but high requirement for temperature rising, grease leakage, anti-dust and anti-water in different conditions.

3. Electromagnetic clutch bearing:mostly are double row angular ball bearings, low radial load, rotation speed ≤6000rpm, according to the working principle of electromagnetic clutch, as the bearing need to bear axial force intermittent and surrounding with water and dust, so high requirement for grease leakage, anti-dust and water proof.    

ZXZ design different types of auto bearings to meet the specific need of applications, and provide excellent solution to ensure that our clients derive maximum benefits from our products.
