三、安裝:
ZT-96型水泥膠砂振實臺的正確安裝對試件的制作和試驗結果至關重要,安裝時請按以下步驟進行。
★按 標準GB/T17671-1999中的4.2.5要求、振實臺安裝在高度約400mm的混凝土基座上。混凝土體積約為0.25m3、重約600kg。需防外部振動影響振實效果時,可在整個混凝土基座下放一層厚約5mm天然橡膠彈性襯墊。并注意機體應有良好的用電安全接地。
★將振實臺用地腳螺釘固定在基座上,安裝后成水平狀態,可用高度尺校正振實臺臺面四角的高度在1mm以內,長度方向水平在0.5mm以內、儀器底座與基座之間安鋪一層新鮮厚砂漿以保證它們*接觸。同時也可用此方法調整臺面和臂桿呈水平
★待水泥膠砂凝結硬化后擰緊地腳螺釘,注意擰緊力應基本一致,防止設備變形,然后將圖“1”所示中臺面(5)抬起,凸頭(4)與定位套(2)A應有卡阻現象,若發現有卡阻現象,一般是水平未校準、應尋找原因后校準。
★地腳螺釘位置如簡圖
Third, the installation of cement sand vibrating table
The correct installation of ZT-96 cement rubber sand vibrating table is very important for the production of test specimens and test results. Please follow the steps below during installation.
★ According to the national standard GB / T17671-1999 4.2.5 requirements, the vibrating table is installed on a concrete base with a height of about 400mm. The concrete volume is about 0.25m3 and weighs about 600kg. When it is necessary to prevent external vibration from affecting the compaction effect, a layer of natural rubber elastic pad with a thickness of about 5mm can be placed under the entire concrete base. And pay attention to the body should have a good electrical safety grounding.
★ The vibrating table is fixed on the base with anchor screws, and it is horizontal after installation. You can use a height ruler to correct the height of the four corners of the vibrating table within 1mm, the length in the horizontal direction is within 0.5mm, between the instrument base and the base Place a layer of fresh thick mortar to ensure that they are in full contact. You can also use this method to adjust the table and boom level
★ Tighten the anchor screws after the cement mortar has hardened. Pay attention that the tightening force should be basically the same to prevent the equipment from deforming. Then lift the middle table (5) shown in Figure "1", the raised head (4) and the positioning sleeve (2 ) A should have jamming phenomenon. If jamming phenomenon is found, the level is generally not calibrated, and calibration should be performed after finding the cause.
★ The position of the anchor screw is as shown in the figure
四、使用與維護:
★操作前應拿掉定位套(見圖1所示),檢查各運動部件是否運動自如,電控部分是否正常,加注潤滑油后開機空轉,檢查一切正常方可使用。每次使用前必須拿掉定位套。
★電氣原理請見附圖。接通電源前,帶鎖開關SW處于閉關狀態(即按鈕彈出位置)。按下開關并鎖住,電機運轉,電子計數器從零計數,當到60次時停轉。再次操作,可按放兩次SW,即能重復執行。
★本電路由于A用電源變壓器,電路部分都與電源電壓有關,外殼必須保證安全接地(認真檢查電源插頭座的PE黃綠線是否安全接地,而A是接電源零線)。
★有油杯的地方加注潤滑油,凸輪表面涂薄機油以減少磨損。
★使用后應清掃儀器上的各種雜物,保持清潔,并將定位套放與原位,以免臺面受力而影響 位置。
★儀器經過一段時間使用后,如振幅變大超差,可用隨機所附墊圈進行調整。具體方法是將止動器固定螺釘松開,取出止動器,將墊圈放入下面重新將固定螺釘上緊。
★振幅檢驗:
A、將隨機所附14.7mm檢驗塊放入圖“1”所示凸面與止動器之間,用手撥動凸輪,凸輪應與軸承相接觸。
B、同樣方法用15.3mm檢驗塊放入,則凸輪與軸承A應接觸,滿足以上兩個條件即儀器振幅為合格。方可進行工作
Fourth, the use and maintenance of cement rubber sand vibrating table
★ Remove the positioning sleeve before operation (see Figure 1), check whether the moving parts move freely, and whether the electric control part is normal. After filling with lubricant, turn on the machine and run idly. Check that everything is normal before use. The positioning sleeve must be removed before each use.
★ Please refer to the attached drawings for the electrical principle. Before the power is turned on, the lock switch SW is in a closed state (that is, a button pop-up position). Press the switch and lock, the motor runs, the electronic counter counts from zero, and stops when it reaches 60 times. Operate again, you can press and release SW twice to repeat the operation.
★ Because the circuit of A uses a power transformer, the circuit part is related to the power supply voltage. The shell must be safely grounded (carefully check whether the PE yellow-green wire of the power plug socket is safely grounded, and A is the power neutral line).
★ Add lubricating oil to the oil cup, and thin the cam surface to reduce wear.
★ After use, clean all kinds of sundries on the instrument, keep it clean, and put the positioning sleeve in place, so as not to be affected by the force on the table surface.
★ After using the instrument for a period of time, if the amplitude becomes too large, it can be adjusted with the enclosed gasket. The specific method is to loosen the stopper fixing screw, take out the stopper, put the washer underneath and tighten the fixing screw again.
★ Amplitude test:
A. Put the attached 14.7mm inspection block between the convex surface and the stopper as shown in Figure "1", and then move the cam by hand. The cam should be in contact with the bearing.
B. Put the 15.3mm inspection block in the same way, the cam and bearing A should be in contact, and the above two conditions are met, that is, the instrument amplitude is qualified. To work
五、工作原理:
水泥膠砂振實臺主要由振動部件,機架部件和接近開關程控系統組成。工作時由同步電動機帶動凸輪轉動,使振動部件上升運動,升到定值后落下,而產生振動使水泥膠砂在力的作用下振實,該儀器采用接近開關計數自動控制,60次后自動停止,使用方便,計數準確。
Fifth, the working principle of cement rubber sand vibrating table
The cement rubber sand vibrating table is mainly composed of vibration parts, frame parts and proximity switch program control system. The cam is driven by a synchronous motor during work to make the vibration component move up and fall after rising to a fixed value. Vibration causes the cement mortar to vibrate under the action of force. The instrument is automatically controlled by the proximity switch counting. Stop, easy to use, accurate counting.
