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(huì)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***。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 </p> <p> UNF 2B），通常可以采用安裝孔測(cè)量?jī)x對(duì)安裝孔進(jìn)行檢測(cè)，以做出適當(dāng)?shù)恼{(diào)整。 </p> <p> 保持安裝孔的清潔：保持安裝孔的清潔并防止熔料堵塞對(duì)保證設(shè)備的正常運(yùn)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(shí)，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(shí)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(duì)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。雅安壓力變送器銷售</p><div
