比泽尔活塞压缩机油压差怎么接线

大家好，和大家分享一下油压差开关接线，这个一号点接电源的火线，它受控于我们交流接触器的这个常开点，也就是说我们压缩机工作时这个一号点才有电，这个呢接零线 这个 l 一 l 二，它是长臂点，它是串联在我们保护电动当中，串联在高低压开关这个线路当中都可以的。 好，我们讲一下这个工作原理，也就是说确油或油过滤器堵塞我们的油牙擦开关，也就是说有一公斤的 保护值，低于油压，低于一公斤的加差，那么这块啊就会闭合，那么我们里面有一个发热电阻，大家看一下， 有这个电阻他就会加热，加热会让我们里面的有个双金属片让他变形，让我们的 l 一 l 二进行断开，起到切断我们保护电路当中的 这个工作，也就说起到一个电路一的一个功能，也就是让我们线圈失电 上就是油牙擦开关接线的视频，有什么不明白的地方可以在我们评论区进行留言，感谢朋友们的收听收看，再见。

show you how to properly disassemble the four vs seven four zero p compressor begin by depressurizing the compressor to do so you will need to extract the refrigerant via the schrader valve before disassembly， you also need to drain the oil the screws on the cover of the compressor terminal box are then loosened using a screwdriver the cover is taken off and the protective conductor on the cover unscrewed the motor protection device can then be removed and the terminal box taken off an impact wrench is used for disassembly the two screws on the discharge shut off valve are loosened and the valve removed the suction shut off valve is also unscrewed and the suction gas filter in the middle of the housing cover removed to start with two screws at the top of the housing cover are removed two m ten parallel pins are mounted on opposite sides to ensure proper removal and prevent the cover from falling off at that point all other screws can be loosened the housing cover is loosened by carefully hitting it on the side with a rubber mallet and the cover pulled off over the parallel pins below it is the rotor which is removed next now loosen the hexagon head screw of the rotor with the impact wrench and take off the balance weight pull the rotor out of the compressor housing using pliers then pull the spacer sleeve off the eccentric shaft and remove it mark the cylinders and valve plates using a water soluble pen to avoid mixing them up when mounting them later on the screws of the cylinder head's opposite each other are loosened using the impact wrench the cylinder heads and valve plates can then be taken off the rubber mallet is hit likely against the cylinder head and valve plate in order to loosen them all the screws are removed using the impact wrench in order to take off the bearing cover the bearing cover is hit likely with the rubber mallet to reduce the pressure of the eccentric shaft on the bearing cover take off the bearing cover and set it aside along with the bearing ring the screws on the oil centrifuge are loosen carefully remove the oil centrifuge and balance weight now it's time to remove the eccentric shaft carefully shift the connecting rods and pull the eccentric shaft out of the connecting rods with light turning movements in order to remove the cylinders the pistons are first taken out of the cylinders one after the other pull from the inside side and press from the outside clean any oil residue from the pistons and carefully place them on a soft surface to check a piston the zig rings are pulled off on both sides and the wrist pins removed loosen the screws on the terminal plate using the impact wrench the terminal plates can then be lifted pull off the cable lugs for the ptc sensor and then remove the six screws in the final step， the terminal plate can now be removed we'll show you how the stator is removed from the housing at the internal bitser service facility we screw the first part of our special tool and the state together then we place the second device on the thread and the stator is pulled out slowly using hydraulics in the final step， the stator is removed high quality bits of components guarantee professional disassembly of our compressors if you have any further questions， please contact our service department。

光电油位开关接线方法，棕色接电源按火线，蓝线接电源按零线， 棕线合成线是长开 no 触点，灰线和粉色线是长 bnc 触点。现在会使用了吗？

千里冰封，一路同行。大家好，我是千里，咱们这一期继续介绍这台比赛压缩机，这是个机械的油位开关，正好有这么一个配件样子的话就是这样子啊，这边是个插头，然后这边是个浮球房，满油的时候 这个浮球阀会上来，浮起来之后这边两个就是个通信号，当缺油的时候掉下去，这边就断开了，断开就机组就油位保护了。现在讲一下这个模块啊，这个模块是这整台压缩机上面一个重要的保护单元，几乎在电气系统没有其他的保护， 只有这个。在机组运行的时候，很多机组会配一个过流保护，但是相当一部分机组连过流保护都不带配的啊，只能通过对电机温度和这个油温或者排气温度这三个参数来进行 一个压缩机的全面保护。所有参数都反映到这个电机保护模块上面，叫 ln， 这是个零线，一二是保护线接点啊，十二是不接的啊，一般接保护的时候是接十四跟十一，直接送到 prc 主板中。 蓝黑这是项序保护，分别接在这一二三上面啊。启动之后，电机保护模块会检测他的项序对不对，如果项序不对，他一样会报压缩机内保护。有些机器会报项序保护， 但是像素保护一定不来自于他，一般像素保护直接来自于机组的控制单元里面的一个像素保护器，这个模块报出来警，一律就叫压缩机内保护。在机组故障检修中， 设备有压缩机内保护，故障的时候基本上就来自于这两个点和通断信号。如果在极端情况下没有这个同型号的这个电机保护模块， 可以用像类似的汉中富盛的模块都可以来替代啊，只是替代的时候把功能点需要接对，更多故障等你来问。感谢关注，再见。
