大國匠芯：國產(chǎn)壓力變送器/差壓變送器日常維護(hù)國際通用版
工業(yè)自動變送器廠家是在工業(yè)生產(chǎn)過程中，對工藝參數(shù)進(jìn)行檢測、顯示、記錄或控制變送器廠家。 工藝生產(chǎn)過程的檢測是了解和控制工業(yè)生產(chǎn)的基本手段，只有在任何時刻都能準(zhǔn)確地了解工藝過程的全貌，并進(jìn)行控制，才能保證生產(chǎn)過程順利，并以高的生產(chǎn)率、小的消耗生產(chǎn)出合格的產(chǎn)品
Industrial automatic transmitter manufacturers are in the process of industrial production, process parameters detection, display, record or control the transmitter manufacturers.The detection of technological production process is the basic means to understand and control industrial production. Only when the overall picture of technological process can be accurately understood and controlled at any time can the production process be smooth and qualified products be produced with high productivity and small consumption
1、檢查安裝孔的尺寸：如果安裝孔的尺寸不合適，傳感器在安裝過程中，其螺紋部分就很容易受到磨損。這不僅會影響設(shè)備的密封性能，而且使壓力傳感器不能充分發(fā)揮作用，甚至還可能產(chǎn)生安全隱患。只有合適的安裝孔才能夠避免螺紋的磨損（螺紋工業(yè)標(biāo)準(zhǔn)1/2-20 UNF 2B），通?？梢圆捎冒惭b孔測量儀對安裝孔進(jìn)行檢測，以做出適當(dāng)?shù)恼{(diào)整。
1. Check the size of the mounting hole: if the mounting hole is not the right size, the threaded part of the sensor will be easily worn during installation.This will not only affect the sealing performance of the equipment, but also make the pressure sensor not fully play a role, and may even cause safety risks.Wear of threads can be prevented only by a suitable mounting hole (thread industry standard 1/2-20 UNF 2B), and the mounting hole can usually be tested with a mounting hole gauge to allow for appropriate adjustments.
2、保持安裝孔的清潔：保持安裝孔的清潔并防止熔料堵塞對保證設(shè)備的正常運行來說十分重要。在擠出機(jī)被清潔之前，所有的壓力傳感器都應(yīng)該從機(jī)筒上拆除以避免損壞。在拆除傳感器時，熔料有可能流入到安裝孔中并硬化，如果這些殘余的熔料沒有被去除，當(dāng)再次安裝傳感器時就可能造成其頂部受損。清潔工具包能夠?qū)⑦@些熔料殘余物去除。然而，重復(fù)的清潔過程有可能加深安裝孔對傳感器造成的損壞。如果這種情況發(fā)生，就應(yīng)當(dāng)采取措施來升高傳感器在安裝孔中的位置。
2. Keep the installation hole clean: it is very important to keep the installation hole clean and prevent the block of melt to ensure the normal operation of the equipment. All pressure sensors should be removed from the barrel to avoid damage before the extruder is cleaned. When the sensor is removed, the melt may flow into the mounting hole and harden. If the residual melt is not removed, the top of the sensor may be damaged when the sensor is reinstalled. The cleaning kit is able to remove the residual material. However, repeated cleaning processes may exacerbate damage to the sensor caused by mounting holes. If this happens, measures should be taken to raise the position of the sensor in the mounting hole.
3，選擇恰當(dāng)?shù)奈恢茫寒?dāng)壓力傳感器的安裝位置太靠近生產(chǎn)線的上游時，未熔融的物料可能會磨損傳感器的頂部；如果傳感器被安裝在太靠后的位置，在傳感器和螺桿行程之間可能會產(chǎn)生熔融物料的停滯區(qū)，熔料在那里有可能產(chǎn)生降解，壓力信號也可能傳遞失真；如果傳感器過于深入機(jī)筒，螺桿有可能在旋轉(zhuǎn)過程中觸碰到傳感器的頂部而造成其損壞。一般來說，傳感器可以位于濾網(wǎng)前面的機(jī)筒上、熔體泵的前后或者模具中
Select the appropriate position: when the pressure sensor is installed too close to the upstream of the production line, the unmelted material may wear the top of the sensor. If the sensor is installed too far back, a stagnation zone of the molten material may be created between the sensor and the screw stroke, where the molten material may degrade and the pressure signal may be distorted. If the sensor is too deep into the barrel, the screw may touch the top of the sensor during rotation and cause damage. Generally speaking, the sensor can be located on the barrel in front of the filter screen, front and rear of the melt pump or in the mold
仔細(xì)清潔；在使用鋼絲刷或者特殊化合物對擠出機(jī)機(jī)筒進(jìn)行清潔前，應(yīng)該將所有的傳感器都拆卸下來。因為這兩種清潔方式都可能會造成傳感器的震動膜受損。當(dāng)機(jī)筒被加熱時，也應(yīng)該將傳感器拆卸下來并使用不會產(chǎn)生磨損的軟布來擦拭其頂部，同時傳感器的孔洞也需要用清潔的鉆孔機(jī)和導(dǎo)套清理干凈。
Careful cleaning; All sensors should be removed before cleaning the cylinder with a wire brush or special compound. Both cleaning methods may cause damage to the vibration membrane of the sensor. When the cylinder is heated, the sensor should also be removed and wiped at the top with a soft cloth that will not cause any wear and holes in the sensor should be cleaned with a clean drill and guide sleeve.
