⑺Check whether there is any debris that hinders its operation when the moving roller shaft system moves horizontally, and whether it may interfere with other equipment, especially whether there are foreign objects or iron blocks between the two grinding rollers and the four bearing seats that hinder the movement of the moving roller;
⑻主機架各聯(lián)接部分安裝就位,聯(lián)接螺栓組均已按規(guī)定擰緊力矩均勻擰緊;
⑻The connecting parts of the main frame are installed in place, and the connecting bolt groups have been evenly tightened according to the specified tightening torque;
5.液壓系統(tǒng)中各壓力控制閥和壓力表參數(shù)的設定關系(參照液壓系統(tǒng)圖).
5.The setting relationship of the pressure control valve and pressure gauge parameters in the hydraulic system (refer to the hydraulic system drawing).
設:⑴電接點壓力表上限壓力為PD上;
Set: ⑴The upper limit pressure of the electric contact pressure gauge is PD;
⑵電接點壓力表下限壓力為PD下;
⑵The lower limit pressure of the electric contact pressure gauge is PD;
⑶蓄能器充氣壓力為Px;
⑶The charging pressure of the accumulator is Px;
⑷電磁液流閥調(diào)定壓力為Pv1;
⑷The set pressure of the electromagnetic liquid flow valve is Pv1;
⑸泵站溢流閥調(diào)定壓力為Pv2;
⑸The setting pressure of the overflow valve of the pumping station is Pv2;
⑹壓力傳感器調(diào)定壓力為PcY;
⑹The set pressure of the pressure sensor is PcY;
⑺低壓腔溢流閥調(diào)定壓力為Pv3;
⑺ The setting pressure of the relief valve in the low pressure chamber is Pv3;
則:⑴PD上-PD下=1.2～2.0Mpa;
Then: ⑴PD up-PD down=1.2～2.0Mpa;
⑵PD下-Px≥0.6～1.5Mpa;
⑵ PD under -Px≥0.6～1.5Mpa;
⑶Px≥0.6PD上;
⑶Px≥0.6PD;
⑷PcY-PD上=2.0～2.2Mpa;
⑷PcY-PD upper=2.0～2.2Mpa;
⑸Pv1-PD上=1.5～2.0Mpa;
⑸Pv1-PD upper=1.5～2.0Mpa;
⑹Pv2-PD上=1.5Mpa;
⑹Pv2-PD upper=1.5Mpa;
⑺Pv3=3.5～4.0Mpa;
⑺Pv3=3.5～4.0Mpa;
設定依據(jù):電接點壓力表上,下限壓力差值越小,擠壓出的物料物理性能一致性越好,但液壓系統(tǒng)工作時有壓力波動,因而一般差值大小按三倍于波動壓力調(diào)定。
Setting basis: On the electric contact pressure gauge, the smaller the lower limit pressure difference, the better the consistency of the physical properties of the extruded material. However, the hydraulic system has pressure fluctuations when it is working, so the difference is generally set at three times the fluctuation pressure.
蓄能器的充氣壓力與電接點壓力表下限越接近,系統(tǒng)加壓的時間就越短,但它們的差值不應小于波動壓力的1.5～2倍,充氣壓力同時不應小于電接點壓力表上限壓力的60%,否則蓄能器內(nèi)的皮囊易損壞。
The closer the charging pressure of the accumulator is to the lower limit of the electric contact pressure gauge, the shorter the time for the system to pressurize. But their difference should not be less than 1.5 to 2 times of the fluctuating pressure, and the inflation pressure should not be less than 60% of the upper limit pressure of the electric contact pressure gauge, otherwise the bladder in the accumulator is easily damaged.
從以上各參數(shù)的設定關系還可看出PY1、PY2、PCY的大小關系為PCY＞PV1＞PV2,這亦反映出系統(tǒng)的三重保護措施:1.當系統(tǒng)壓力超過泵站溢流閥設定壓力PV2時,則通過該溢流閥卸壓,對系統(tǒng)起保護作用;2.若泵站溢流閥失靈,則通過電磁溢流閥對系統(tǒng)卸壓,同樣起到保護作用;3.若以上兩溢流閥都失靈,則通過壓力傳感器將系統(tǒng)壓力傳給控制系統(tǒng),由控制系統(tǒng)實行聯(lián)鎖停機。
From the setting relationship of the above parameters, it can be seen that the size relationship of PY1, PY2, and PCY is PCY>PV1>PV2, which also reflects the system's triple protection measures: 1. When the system pressure exceeds the set pressure PV2 of the overflow valve of the pumping station, the pressure is relieved through the overflow valve to protect the system; 2. If the overflow valve of the pumping station fails, the electromagnetic overflow valve is used to relieve the pressure of the system, which also plays a protective role; 3. If the above two overflow valves fail, the system pressure is transmitted to the control system through the pressure sensor, and the control system implements interlocking shutdown.
根據(jù)原理圖可看出,系統(tǒng)的最高壓力為16.0Mpa,工作壓力依據(jù)具體情況而定,一般為7～9Mpa。
It can be seen from the schematic diagram that the maximum pressure of the system is 16.0Mpa, and the working pressure depends on the specific conditions, generally 7-9Mpa.
7.液壓系統(tǒng)試車
7. Hydraulic system commissioning
液壓系統(tǒng)主要可劃分為以下三個回路:加壓回路,退輥回路,壓力保護回路,在進行試車時,可按以下步驟進行:
The hydraulic system can be divided into the following three circuits: pressurization circuit, roll back circuit, pressure protection circuit, during the test run, the following steps can be carried out:
⑴調(diào)試泵站壓力,檢驗齒輪泵和油泵電機的工作性能
⑴ Debug the pressure of the pump station, check the working performance of the gear pump and oil pump motor
①將泵站溢流閥(件6)手柄調(diào)于最松狀態(tài);
① Adjust the handle of the pump station relief valve (part 6) to the most loose state;
②三位四通換向閥(件7)處于失電狀態(tài);
②The three-position four-way reversing valve (part 7) is in the power-off state;
③啟動油泵電機;
③Start the oil pump motor;
④確認電機及油泵運轉(zhuǎn)正常平衡后,緩慢擰緊溢流閥手柄,以1Mpa為一遞升速度,使油泵壓力為逐步上升至10Mpa,在此期間注意其調(diào)節(jié)是否靈活。
④ After confirming that the motor and the oil pump are running normally and balanced, slowly tighten the relief valve handle, and use 1Mpa as the step-up speed to gradually increase the oil pump pressure to 10Mpa. During this period, pay attention to whether its adjustment is flexible.
注:在調(diào)試過程中,若出現(xiàn)齒輪泵密封圈處往外冒油,則可考慮是否油泵電機反接。
Note: During the debugging process, if oil is leaking from the gear pump seal ring, you can consider whether the oil pump motor is reversed.
⑵用進輥油路給系統(tǒng)排氣
⑵Using the roller inlet oil circuit to exhaust the system
①根據(jù)設定的充氣壓力給蓄能器充氣;
① Inflate the accumulator according to the set inflation pressure;
②將各元件調(diào)至使移動輥推進的狀態(tài);
② Adjust the components to the state where the moving roller is pushed forward;
③起動油泵電機,以設定的壓力給系統(tǒng)充油排氣。注意觀察兩側(cè)排氣閥處(或壓力表開關安裝處)是否有油冒出。若兩側(cè)都沒冒油或只有一側(cè)冒油,都應繼續(xù)往系統(tǒng)中充油,直到出油為止。待系統(tǒng)中氣體都排出后,方可擰緊排氣閥(或裝好壓力表)。
③Start the oil pump motor and fill the system with oil and exhaust at the set pressure. Pay attention to whether there is oil coming out of the exhaust valve on both sides (or at the pressure gauge switch installation place). If there is no oil on both sides or only one side, you should continue to fill the system with oil until the oil comes out. Tighten the exhaust valve (or install the pressure gauge) after the gas in the system is exhausted.
注:在只有一側(cè)冒油的情況下,可將該側(cè)的排氣閥擰緊關閉,再往系統(tǒng)中充油。
Note: When only one side is emitting oil, the exhaust valve on that side can be tightened and closed, and then the system can be filled with oil.

⑵ Start the motor, pay attention to the positive and negative connection of the motor, and observe whether the pipe joints of each lubrication point are oily;
-
由于各個潤滑油路的長度不一致，當各個潤滑點的管接頭出油后，應立即關閉此油路的供油開關，并與各個潤滑點依次連接好，避免浪費潤滑油。
⑶ Since the length of each lubricating circuit is inconsistent, when the pipe joints of each lubricating point are out of oil, the oil supply switch of this oil circuit should be turned off immediately and connected to each lubricating point in order to avoid wasting lubricating oil.
-
在潤滑電機不發(fā)熱的前提下,將導軌,端蓋處充滿油脂,直到看到有潤滑油溢出來為止。
⑷ On the premise that the lubricating motor does not generate heat, fill the guide rail and end cover with grease until you see the lubricating oil overflow.
-
然后根據(jù)設備各個潤滑點的使用情況，在潤滑系統(tǒng)的控制柜中，依次設置好各個潤滑點的加油次數(shù)，加油時間。
⑸ Then according to the usage of each lubrication point of the equipment, in the control cabinet of the lubrication system, set the refueling times and refueling time of each lubrication point in sequence.

⑵將移動輥推到頭,檢測原始輥縫并作記錄;
⑵Push the moving roller to the end, detect the original roller gap and make a record;
⑶抽動位移傳感器的活動桿于不同位移量時,檢測二次儀表顯示的線性度;
⑶ The movable rod of the twitch displacement sensor detects the linearity displayed by the secondary meter when the displacement is different;
⑷找出感應式位移傳感器的線性工作段，將傳感器的外殼安裝于適合的位置上；
⑷ Find out the linear working section of the inductive displacement sensor, and install the housing of the sensor in a suitable position;
⑸以所檢測的原始輥縫為初始量，將位移傳感器的活動桿固定于移動輥軸承座上。并注意其安裝是否牢固。
⑸ Fix the movable rod of the displacement sensor on the bearing seat of the movable roller with the detected original roller gap as the initial quantity. And pay attention to whether its installation is firm.
2、軸承溫度檢測
2. Bearing temperature detection
⑴檢查端面熱電阻的接線和二次儀表接線是否正確；
⑴Check whether the wiring of the end surface thermal resistance and the secondary instrument wiring are correct;
⑵用標準溫度計檢驗端面熱電阻在0℃～80℃內(nèi)的溫度誤差值是否在產(chǎn)品規(guī)定的范圍內(nèi)；
⑵Use the standard thermometer to check whether the temperature error value of the end face thermal resistance within 0℃～80℃ is within the specified range of the product;
⑶將校驗后的端面熱電阻裝于主軸承外端蓋上。注意熱電阻元件端面應與主軸承外圈保持良好的接觸。而熱電阻上的彈簧又不可壓得過緊，以防損壞元件。
(3) Install the calibrated thermal resistance on the outer end cover of the main bearing. Note that the end face of the thermal resistance element should keep good contact with the outer ring of the main bearing. The spring on the thermal resistance should not be too tight to prevent damage to the components.
3、液壓系統(tǒng)壓力檢測
3. Hydraulic system pressure detection
⑴檢查確認壓力傳感器及顯示儀表的接線是否正確；
⑴Check whether the wiring of the pressure sensor and display instrument is correct;
