文檔簡介

1、<p><b>  附錄</b></p><p><b>  中文翻譯</b></p><p>  乳化液泵站 這個乳化液泵站由4個乳液泵,兩個水箱和一個蓄能器組成。每個水箱模塊包含一個離心泵為四個乳化液泵供應(yīng)乳化液。清水通過過濾器和電液灌裝閥進(jìn)入第一水箱,這個水箱里有沒有混合的油,水進(jìn)入這個水箱時形成乳化液。第一水箱配備有3等

2、級(最大,最小和低-低) 和一個溫度報警器。溫度報警器防止乳化液溫度過高產(chǎn)生氣泡。 每個乳化液泵配備了一個電液卸荷閥和彈簧加載卸荷閥。這個彈簧加載卸荷閥使乳化液泵在沒有PLC的控制下通過彈簧的加載和卸載維持泵的壓力。在正常運行情況下電液卸荷閥運行在此模式下通過機械操作使卸載閥不再工作。 為了保證乳化液泵不在沒有乳化液的情況下運行,每個乳化液泵都配備了增壓報警器。該報警器是為了油溫和油壓過高,此外該加壓油路配備了機油濾清

3、器。從高壓泵流出的乳化液通過高壓過濾器這樣保證了乳液泵的清潔。 </p><p>  PLC控制 PLC控制單元位于乳化液泵站和能夠在兩邊控制的泵站的蓄能模塊。通過壓力顯示PLC是完全防爆的。 一個完整的系統(tǒng)包含一個主要的BBCM單元,BBCM包含PLC和20個DPM - C1的總線模塊。PLC的外部防爆裝置是完全安全的。防爆的PLC的本質(zhì)作用是使總線系統(tǒng)安全。   </

4、p><p>  系統(tǒng)的總線包含所有的輸入和輸出。經(jīng)由PLC的輸出在本質(zhì)上都是安全的。 所有的報警系統(tǒng)和高壓泵,增壓泵的控制和設(shè)置都是由PLC控制的且所有信息都是數(shù)字顯示的。</p><p>  此外沒個動力裝置的啟動和停止都獨立的模塊,為了安全起見動力裝置都是電子隔離的。</p><p>  如圖所示PLC的輸入輸出報警和啟動系統(tǒng) 動力裝置的操作的由PLC監(jiān)

5、控的,如果PLC發(fā)出啟動信號同時發(fā)出監(jiān)測信號。</p><p>  每臺HP泵里都有油溫油壓報警器和增壓報警器來保護(hù)齒輪箱,如果正在運行的泵報警將會停止運行PLC使備用泵自動運行,且所有的報警線路同一時間被檢查。</p><p>  水和乳化液箱配備了電子指示儀。這個指示儀會指示出液面的高,低,低-低水平,如果低-低報警,泵將停止運行否則泵將會在沒有乳化液的情況下運行。如果在液面高時報警電

6、液伺服閥停止運行,通過手動球閥控制液面高度油箱是乳化液泵箱的一部分。它配備了高低液面報警器,這個報警器只會顯示液面的高度,不會使泵停止運行。 水箱和乳化液箱的溫度高于50 ℃ 報警器將會報警。報警不會使泵停止運行,但報警信號會在PLC上顯示。 水泵站配備了壓力傳感器如果壓力太低將會報警,因此操作者應(yīng)經(jīng)常檢查泵站。 </p><p>  通過PLC操作者可以設(shè)置泵的最高和最低壓力。將泵編號從1-3。

7、4號泵是備用泵。系統(tǒng)的壓力由壓力傳感器監(jiān)測,如果系統(tǒng)的壓力低于1號泵的壓力則1號泵觸發(fā)電磁閥控制卸荷閥。如果系統(tǒng)的壓力不上升,2號泵將會延遲啟動。如果壓力還不上升,3號泵啟動。如果三臺泵里有任何一臺報警4號泵啟動。 可以通過PLC改變泵的編號。這樣可以確保每臺泵在相同的負(fù)載情況下運行。1號泵運行的時間比2號泵長,2號泵比3號泵長,在正常情況下備用泵不運行 。 泵的壓力調(diào)節(jié)。 泵均設(shè)有手動壓力調(diào)節(jié)器。這就要求沒

8、有PLC。壓力的控制只能通過PLC。</p><p>  另外一到二個輸出壓力的調(diào)節(jié)可以低于系統(tǒng)的壓力。</p><p>  技術(shù)數(shù)據(jù) 技術(shù)數(shù)據(jù)乳液抽水站 主要參數(shù) 類型: K 35055 M – E 315 B 額定流量(升/分鐘) : 439升/分 額定壓力( MPa ) : 37.5兆帕 結(jié)構(gòu)類型:三缸柱塞泵\ 模型泵: K 3

31、water tanks and one accumulator module. Each tank module carries in addition a centrifugal pump to supply two of the four emulsion pumps with fluid. The fresh water is fed through a filter and an electro hydraulic fillin

32、g valve into the first tank. This tank includes a raw oil tank and a CONFLOW emulsion mixer. When the fresh water passes the mixer emulsion is produced. The first tank is equipped with three level (max. min and low-low)

33、and one te</p><p>  Each Emulsion pump is equipped with an electro hydraulic unloading valve and a spring loaded unloading valve. This spring loaded unloading valve allows to run the emulsion pumps without a

34、ny PLC control just by setting the spring on the spring loaded unloader to the desired pressure level. Normal operating mode will be running the electro hydraulic unloading valve. In this mode the mechanically operated u

35、nloading valve is not working at all.</p><p>  To assure that the pumps are not running dry each pump is equipped with a booster pressure alarm. The gear case is protected by an oil pressure and oil temperat

36、ure alarm. In addition the pressurized oil circuit is equipped with an oil filter.</p><p>  From the high pressure pumps the fluid is pumped through high pressure filters that assure that the emulsion pumped

37、 to the Longwall face is clean.</p><p>  PLC Control</p><p>  The central PLC unit is located on the accumulator module of the emulsion pumping station and can be operated from both sides of the

38、 pump station. In a pressure proof compartment the PLC is explosion proof installed.</p><p>  The complete system consists of one main unit BBCM that contains the PLC and 20 bus modules DPM-C1. Outside the c

39、ompartment of the PLC all elements are intrinsically safe. In the Compartment of the PLC the Power supplies and the dividing elements in between the intrinsically safe bus system and the PLC are located.</p><p

40、>  The bus system connects all inputs and outputs. Everything located outside the PLC housing is intrinsically safe. All functions and alarms of the system can be set or controlled at the PLC and all booster and high

41、pressure pumps can be started from here. Interfaces for all motors are available to trigger the power supply. All information is given on a digital display.</p><p>  In addition every motor can be started or

42、 stopped locally at the individual module. For safety reasons during service every motor can be electrically isolated.</p><p>  The enclosed schematic of the input and output structure of the PLC system show

43、s all alarms and starters. </p><p>  The operation of the motors is monitored by the PLC. If the start signal is given the PLC also monitors if the motors are running.</p><p>  Each HP-pump gear

44、 case is protected by an oil pressure and oil temperature alarm on the gear case as well as by a booster pressure alarm on the inlet of the pump. If on alarm is active the pump will be stopped and the stand-by pump will

45、be started automatically by the PLC. All alarm wires are all the time checked if they are all right.</p><p>  The water and emulsion tanks are equipped with electronic level indicators. This includes high, l

46、ow and low-low alarms for the fluid-level. The low-low alarm stops the pumps automatically otherwise they would run dry. The high level alarm closes the water inlet. If the electro-hydraulic inlet valve is not operating

47、it can be by-passed by a manual ball valve.</p><p>  The oil tank that is located in one of the emulsion tank is equipped with a low and a high level alarm. This alarm will only be indicated but will not sto

49、ay.</p><p>  The water pumping station is equipped with a pressure transducer to monitor the outlet pressure. If the pressure is too low an alarm will be indicated, so the operator should check the pump stat

50、ion. </p><p>  In the PLC for each pump a max and a min pressure can be set by the operator. The pumps are numbered from one to three. The fourth pump will be the stand-by pump. The system pressure is monito

51、red by a pressure transducer. If the system pressure sinks below the min pressure of pump one, the pump No. 1 is loaded by triggering the solenoid valve that controls the unloading valve. If the system pressure does not

52、rise, number two pump is started after a programmable time delay. If again the pressure </p><p>  It is possible to change the numbering of the pumps in the PLC. This should be done regularly to assure that

53、all pumps acquire the same running hours under load. The number one pump will run more frequently than number two. And number two will run longer than number three. The stand-by pump is stopped in normal mode.</p>

54、<p>  The water pumps are equipped with manual pressure regulators. This requires no PLC. The pressure is only monitored by the PLC.</p><p>  In addition the pressure of one of the two outlet can be re
