搅拌拖泵调试工艺介绍

三民重科搅拌拖泵都需要经过严格的调试后才能出厂,如何对搅拌拖泵进行调试了,三民重科小编告诉您:


调试前的准备工作


a、加注AW46(或低温AW32)液压(ya)油(you),应(ying)用滤(lv)油(you)机加油(you)。


b、加注润(run)滑(hua)(hua)脂,夏季(ji)用“OO”型(xing)(xing),冬季(ji)用“OOO”型(xing)(xing),摇动润(run)滑(hua)(hua)脂泵(beng),使润(run)滑(hua)(hua)脂到各(ge)润(run)滑(hua)(hua)点。


c、洗涤室(shi)必须加满清水。


d、主(zhu)油泵、防水阀排(pai)空(kong)气(qi)(qi),风(feng)冷马达排(pai)空(kong)气(qi)(qi),将排(pai)气(qi)(qi)螺堵(du)拧开,有油流(liu)出(chu)即将螺丝(si)拧紧。


e、电(dian)(dian)(dian)(dian)(dian)动(dong)机(ji)(ji)拖泵需接(jie)三相(xiang)电(dian)(dian)(dian)(dian)(dian)源并确(que)定(ding)电(dian)(dian)(dian)(dian)(dian)动(dong)机(ji)(ji)正反(fan)转,从(cong)泵座的(de)观(guan)察口(kou)看电(dian)(dian)(dian)(dian)(dian)机(ji)(ji)输(shu)出轴的(de)旋转方向——从(cong)电(dian)(dian)(dian)(dian)(dian)机(ji)(ji)轴端看电(dian)(dian)(dian)(dian)(dian)机(ji)(ji)逆时针方向旋转,若电(dian)(dian)(dian)(dian)(dian)机(ji)(ji)旋转方向不对,则将电(dian)(dian)(dian)(dian)(dian)源任意(yi)两面(mian)相(xiang)交(jiao)换位(wei)置接(jie)上即(ji)可。


f、在主阀(fa)块至主油缸(gang)之(zhi)间串入滤油车


各系统压力(li)调节方法,主油泵功率调节方法


各系统压力调节方法


将主(zhu)油(you)泵的(de)恒(heng)(heng)压(ya)(ya)(ya)阀(fa)(fa)调(diao)(diao)(diao)节(jie)(jie)杯全部拧(ning)紧(jin)(jin),恒(heng)(heng)功率调(diao)(diao)(diao)节(jie)(jie)杆(gan)按出厂时位置暂(zan)时不动(dong),按点(dian)动(dong)后(hou)退(tui)按钮,电(dian)动(dong)机转速升(sheng)到1500rpm左右(you),观(guan)(guan)看主(zhu)系统压(ya)(ya)(ya)力(li)(li)表(biao),慢慢调(diao)(diao)(diao)紧(jin)(jin)溢(yi)(yi)流阀(fa)(fa)调(diao)(diao)(diao)节(jie)(jie)杆(gan)直至压(ya)(ya)(ya)力(li)(li)显(xian)示为(wei)(wei)34mpa,锁紧(jin)(jin)溢(yi)(yi)流阀(fa)(fa)调(diao)(diao)(diao)节(jie)(jie)杆(gan)。接上(shang)(shang)步,慢慢拧(ning)松主(zhu)油(you)泵上(shang)(shang)恒(heng)(heng)压(ya)(ya)(ya)阀(fa)(fa)调(diao)(diao)(diao)节(jie)(jie)杆(gan),将压(ya)(ya)(ya)力(li)(li)降至31.5mpa,锁紧(jin)(jin)恒(heng)(heng)压(ya)(ya)(ya)阀(fa)(fa)调(diao)(diao)(diao)节(jie)(jie)杆(gan)。(若主(zhu)油(you)泵为(wei)(wei)2个,则(ze)需单独调(diao)(diao)(diao)节(jie)(jie),即在(zai)主(zhu)油(you)泵上(shang)(shang)测(ce)压(ya)(ya)(ya)接头上(shang)(shang)接压(ya)(ya)(ya)力(li)(li)表(biao),分别调(diao)(diao)(diao)节(jie)(jie)油(you)泵上(shang)(shang)恒(heng)(heng)压(ya)(ya)(ya)阀(fa)(fa)的(de)调(diao)(diao)(diao)节(jie)(jie)杆(gan),将压(ya)(ya)(ya)力(li)(li)降至31.5mpa.)以(yi)同样方法点(dian)动(dong)后(hou)退(tui)弊压(ya)(ya)(ya)调(diao)(diao)(diao)节(jie)(jie)换向溢(yi)(yi)流阀(fa)(fa),关闭(bi)(bi)蓄能器卸荷球阀(fa)(fa),将换向溢(yi)(yi)流阀(fa)(fa)的(de)调(diao)(diao)(diao)节(jie)(jie)杆(gan),慢慢拧(ning)紧(jin)(jin),观(guan)(guan)察换向压(ya)(ya)(ya)力(li)(li)表(biao),压(ya)(ya)(ya)力(li)(li)指示为(wei)(wei)16mpa时,停止调(diao)(diao)(diao)节(jie)(jie),锁定调(diao)(diao)(diao)节(jie)(jie)杆(gan);同样的(de)方法关闭(bi)(bi)搅拌球阀(fa)(fa),弊压(ya)(ya)(ya)升(sheng)速,然后(hou)调(diao)(diao)(diao)节(jie)(jie)搅拌溢(yi)(yi)流阀(fa)(fa)调(diao)(diao)(diao)节(jie)(jie)杆(gan),观(guan)(guan)察压(ya)(ya)(ya)力(li)(li)表(biao)为(wei)(wei)12mpa时,此时,各(ge)系统压(ya)(ya)(ya)力(li)(li)调(diao)(diao)(diao)节(jie)(jie)完毕。


主油泵的功率调节方法


此型(xing)拖(tuo)泵(beng)调功率(lv)时主要是(shi)观察电(dian)(dian)流值(zhi)来确(que)定(ding)主油泵(beng)的(de)功率(lv),具体方法如下(xia),将主油泵(beng)的(de)恒(heng)压调节(jie)(jie)(jie)杆(gan)锁死,然(ran)后(hou)调节(jie)(jie)(jie)恒(heng)功率(lv)杆(gan),点动(dong)后(hou)退弊压观察,电(dian)(dian)流表(biao)示(shi)值(zhi),当电(dian)(dian)流值(zhi)为140A时(此电(dian)(dian)流值(zhi)为电(dian)(dian)动(dong)机的(de)额(e)定(ding)电(dian)(dian)流,此型(xing)拖(tuo)泵(beng)所匹配电(dian)(dian)动(dong)机额(e)定(ding)电(dian)(dian)流一般为140A,在(zai)调节(jie)(jie)(jie)时可跟实际(ji)情况而(er)定(ding),)停(ting)止调节(jie)(jie)(jie),锁定(ding)恒(heng)功率(lv)调节(jie)(jie)(jie)杆(gan),此时功率(lv)调节(jie)(jie)(jie)完(wan)毕,拧松恒(heng)压杆(gan),调节(jie)(jie)(jie)压力和功率(lv)调节(jie)(jie)(jie)可同步进行。如下(xia)图
