Ebyuma ebikuba ebifaananyi (die-casting machines) biyinza okuba n’ensobi ez’enjawulo mu kiseera ky’okukozesa. Okutegeera ensobi eza bulijjo n’ebiziviirako, era okukuguka mu nkola z’okuddaabiriza ezikwatagana kyetaagisa okukakasa enkola eya bulijjo ey’ekyuma ekikuba ebifaananyi (die-casting machine).
Ensobi eza bulijjo ez’ebyuma ebikuba ebifaananyi (die-casting machines):
Emmere emala .
The reasons may be multifaceted. During the conveying process, if the material channel is blocked, such as impurities and residues accumulated in the material pipe, it will hinder the normal conveying of the material, resulting in insufficient feed. Insufficient raw materials are also one of the common reasons. If the amount of raw materials in the hopper is too small to meet the die-casting requirements, insufficient feed Kijja kubaawo. Okugatta ku ekyo, ensengekera oba embeera y’ekibumbe nayo eyinza okukosa emmere. okugeza, obunene bw’omulyango gw’ekibumbe butono nnyo, omuddusi taseeyeeya, oba waliwo okuzibikira munda mu kibumba, ekijja okulemesa emmere.
Pampu ya woyiro tesobola kutandika .
Oluvannyuma lw’okunyiga button ya oil pump start, singa etunuuliddwa nti motor relay tesikiriza, kiyinza okuba nti motor thermal relay ekola oba okwonooneka, ekivaako circuit okulemererwa okukola mu ngeri eya bulijjo. incorrect power supply circuit, gamba nga line break, short circuit oba wiring error, era kiyinza okulemesa woy pump okutandika{1} okugatta, abnormal contact of starting ne stop curcuit, okuggulawo CORUCUL CORUCUL COURTRIC the start of the oil pump. If the relay is energized after pressing the oil pump start button, but the oil pump still cannot start, it may be that the oil pump itself is damaged and stuck, or the line from the relay to the motor is abnormal, or the oil pump is assembled too tightly, it is not easy to turn the coupling by hand, or the axial movement of the coupling gap is not appropriate (normal should be about 3-5mm) . .
Nywa ku bbaatuuni ya Oil Pump Start, The Thermal Relay Trips .
Kino kikwatagana n’ensonga nga current, load n’okumanya oba resistance ya phase essatu eba ya symmetrical. singa motor thermal relay eyonoonebwa oba seti current eba ntono nnyo, thermal relay ejja kugwa mu ngeri ennyangu. nga voltage eri wansi nnyo, current ejja kweyongera oba three-phase voltage ejja kuba unbalanced, cause the thermal winding to trip trip{} {4} un resistance of the three- winding to the thermal winding to trip to trip {4} Ebizibu. Okugatta ku ekyo, puleesa yonna oba okutereeza puleesa ya ppampu ey’emirundi ebiri kuli waggulu nnyo, ekivaako ekyuma okutikka ennyo, oba ppampu ya woyiro eyonoonebwa oba okukuŋŋaanyizibwa ennyo, ekireetera mmotoka okutikka ennyo, ekijja okuvaako thermal relay okutambula.
Tewali puleesa yonna .
After the oil pump starts, press the pressure start button, first observe whether the pressure and flow indicating ammeters have indications to determine whether the electromagnetic coil of the proportional pressure valve (proportional relief valve) has current, so as to distinguish whether it is an electrical or hydraulic fault. If there is current output, it may be due to the oil pump reversal (people face the direction of the oil pump shaft, clockwise rotation is positive rotation), or the relief valve is improperly adjusted or stuck, the stop valve is closed, the throttle valve of the proportional relief valve is lost or loose, etc. If there is no current output, it may be due to abnormal rectifier board, improper adjustment or damage of pressure proportional amplifier board, abnormal computer operation, abnormal line between pressure start button and computer, abnormal line between electric proportional board output and oil valve, abnormal electric proportional coil, code ya pressure dial etali ya bulijjo, etc.
Tewali kikolwa kya otomatiki .
Check whether the safety door limit switch is normal and whether the relevant action returns to the origin. For example, for the Lijin horizontal cold chamber die casting machine, before automatic action is performed, the safety door input signal, automatic input signal, clamping input signal, ejector return limit input signal, and return hammer arrival position should be satisfied. If the manual action is abnormal, the manual action fault should be checked and eliminated first.
Tekisoboka kutereeza kikuta .
Enkola y’okutereeza ekikuta bw’erondebwa okukola era ekyuma ne kitasobola kutuuka ku ntambula y’okutereeza ekikuta, sooka okebere oba embeera z’entambula y’okutereeza ekibumbe zituukirira, oba omuwendo gwa puleesa y’okutereeza ekibumbe guteekebwa wansi nnyo, era oba engeri y’okukola mu ngalo ntuufu. bwe waba tewali buzibu na birimu bino, kebera oba ekibumbe ekitereeza amazzi motor kisibiddwa oba ekikuta ky’okutereeza ekibumbe kyonoonese, oba enkola y’okutereeza ekibumbe ya valve ey’okutereeza ekikuta ekikwatiddwa, oba nga kikwatiddwa ekibumbe kya ttanibboodi kibeera kifuuse ekikuta ky’ekikuta ky’ekikuta ky’ekikuta ky’ekikuta ky’ekikuta kyonooneddwa, oba enkola ya wold adjustment adjustment valve Hydraulic Ekwatiddwa. .
