before installation should check whether the oil seal of the pump is good, and check the pump is damaged in transportation, turn the coupling usable hand card trouble phenomenon, if there is any should tear open pump for cleaning, repair and calibration.2, installation of pump suction and discharge of oil pipe, the pipe diameter shall not be less than the oil inlet of the pump and the oil outlet diameter, inlet pipe shall not be too long, elbow shall not too much, otherwise will affect the pump working condition.3, when more than two head of pump installed in the same line, to facilitate pump start-up, in close to the oil drain pump must be installed on a non-return valve.4, for under high temperature (above 60 ℃) conveying the viscosity of oil (such as: heavy oil) of the standby pump, it must be hot standby pump, otherwise the pump at low temperature can cause the damage of motor overload or pump.(suggest near the exhaust non-return valve on the tubing pump, a small return valve installed in parallel, differentiable and the backflow preventer to standby pump, the pump slow reversal, the reverse speed 100 r/min or less, often make some hot oil flows through the pump, to pump hot standby purposes).5, mechanical impurity is contained within the transmission medium.Will seriously affect the operation and reduce the service life of pump, so before the pump installation, must be carefully clean up the feed tube welding slag, impurities such as grains of sand, and shall be installed in the inlet pipe near the pump filter, filter mesh size, is decided according to the working condition and medium viscosity.Available (40 ~ 80 mesh net), filter area generally shall not be less than 20 times into the cross-sectional area of the tubing.6, as far as possible in the pump suction and discharge of oil on the threaded hole mouth connect pressure gauge and vacuum gauge, in order to observe the pump running state.7, prime mover and the pump shaft must be in the same center line, available ruler feeler gauge in the coupling of the circumference of a circle by 90 ° in check.8, steering engine and pump must be consistent, strictly prohibited prime motor driven pump reversal.Electrical wiring, should first release coupling of motor and pump, a test run on the motor.The steering pump and steering sign agreement. 3G型(xing)三螺杆(gǎn)泵的使(shi)用1、泵啟(qǐ)動前，必(bì)須全開(kai)進油和(he)排油閘(zha)閥。2、首次(ci)啟動泵(bèng)或再次(cì)使用長(zhang)期封存(cun)的泵時(shi)，泵内無(wu)介質，應(ying)在泵的(de)進油腔(qiāng)灌注适(shi)量輸送(song)介質，避(bi)免泵幹(gan)啟動。3、泵(beng)啟動後(hou)，應密切(qiē)注意電(diàn)流表，壓(yā)力表和(hé)真空表(biǎo)的數值(zhi)，超出規(guī)定值時(shí)，應停泵(beng)找出原(yuan)因後，再(zài)行啟動(dòng)。4、軸封處(chù)點滴洩(xie)露，應屬(shǔ)正常現(xiàn)象，當洩(xie)露量大(da)量增加(jiā)時，對軟(ruan)填料密(mì)封應壓(ya)緊填料(liào)壓蓋，對(duì)機械密(mi)封應停(ting)泵修複(fú)後，再行(háng)啟動。5、用(yòng)高溫蒸(zhēng)汽清掃(sao)管線時(shi)，應避免(miǎn)高溫蒸(zhēng)汽通過(guo)泵内。6、如(rú)果泵長(zhǎng)期不工(gong)作時，應(yīng)進行油(yóu)封，并定(ding)期檢查(chá)油封情(qíng)況，必要(yào)時重新(xin)油封。The use of 3 g type three-screw pump 1, before starting the pump, oil inlet must be fully open and oil discharge gate valve.2, start the pump for the first time or again for a long time use of the pump, the pump inside without medium, should be in the inlet of the pump cavity perfusion amount transfer medium, avoid dry start pump.3, the pump starts, should pay close attention to current meter, pressure gauge and vacuum gauge value, beyond the specified value, should stop pump after find out, start again.4, shaft sealing drip leakage, should belong to the normal phenomenon, when the leak amount of increase, the soft packing seal should be compression packing gland, to pump mechanical seal shall be shutdown after repair, start again.5, with high temperature steam cleaning pipeline, should avoid high temperature steam through the pump.6, if the pump is not working for a long time, should carry on the oil seal, and regularly check oil seal, oil seal again if necessary.
