如何维护您的Vezin采样器

While gearbox failures are a very rare occurrence with Vezin取样器, the oil within the gearbox should be replaced at regular intervals. 

The oil change interval will vary by application and depends primarily on the amount of time the sampler is in operation. A 24/7 operation will obviously require more frequent service than an eight-to-12-hour–a-day operation.

Regardless, a good starting point is approximately every six months. 从这个起点, you can simply adjust the oil change interval upward or downward based on the condition of the used oil.

即使在轻型应用中, the constant flow of material over the cutter lip assemblies will wear the edges of this component over time. 

While wear of this component does not affect the operation of the machine itself, worn cutter lips will have a negative impact on the samples collected. Excessively worn cutter lips will generate errors with samples collected.

Cutter lips are not a high wear item, but they should still be monitored at regular intervals. The length of the inspection interval is again determined by the amount of operating time and flow rate for a particular application. Higher operating times and higher flow rates result in increased wear, which in turn lead to shorter time periods between inspections.

A good starting time frame for inspection is every one to three months. Adjust the inspection interval from this point based on observations from previous inspections.

而它们不影响机器的运行, door and access panel gaskets play an important role in sealing the sampler from the outside environment and preventing the escape of fugitive material.

The gasket material itself is a stable material that could last a long period of time if it were simply installed and left alone. 在现实中, 然而, repeatedly removing and replacing access panels along with the opening and closing of inspection doors will cause accelerated wear of the gasket material. 

It is difficult to state a typical time frame for the inspection of gasket material since any one particular instance of access/maintenance to the sampler could result in damage to the seals.

而不是, it is likely better to simply perform a quick check of any gasket material that is present around an inspection panel or access door each time the panel is removed or the door is opened. In this way, any damaged gasket is noticed and can be replaced quickly. 

在下列情况下，应更换垫片材料:

• 有缺失的部分
• 有松散的部分 
• The gasket material has been abraded away to the point where a good seal is no longer possible

It is most common to see spray bars and nozzles in Vezin取样器 used for slurry sampling applications, but spray bars and nozzles are a fairly common option and do require some periodic inspection and maintenance. 

The maintenance issues involving these components are generally focused around whether or not the there is a blockage of some kind, or if the valve arrangement that operates the water flow is functioning correctly.

然而，最常见的是水流堵塞. 通常, this takes place at the nozzle itself and can be the result of buildup from either inside or outside of the nozzle, 但通常是两者的结合.

Buildup from splashing slurry can slowly accumulate on the outside the spray bar and nozzles, slowly building to the point where flow out of the nozzle is impeded, 然后最终停止了. 类似的, particulates that are suspended in the wash water will slowly build up inside the nozzle, 慢慢关闭喷嘴的开口.
