Hydraulic steering gear Common Troubleshooting

Of oil; cleaning or replacement of filters. ⑦ excessive wear and tear pump oil pump failure, the pass undetected large. Check the pump work, repair or replace pump. ③ human steering check valve is not installed; debris Court, paving the way to ball and ball seat Mifengbuyan; check valve ball off one valve cover and valve ring groove of the question, when these can lead to a single power steering to the valve closed, and out of port connectivity. Check the check valve installation; check the oil is clean. Cleaning steering; check check valve ball and seat sealing case, when strict repair by grinding, and then dress up the new ball. ④ diverter valve failure, premature opening. Check the valve spring is not deformed or failure. If the lack of spring tension, spring and spring seat can be asked to increase the gasket. ⑤ spool and valve sleeve deformation, resulting in both stuck. Installed at the inlet a small amount of hydraulic oil filling, and then turn the valve should be flexible, if cable wiring should be grinding. Sometimes the bottom of the steering bolt tightening when the force is uneven, the phenomenon also appears stuck spool, the correct approach is to sub-Q every 2 to 3 times tighten the bolts evenly. (2) because the steering deviation of steering wheel and the valve core suite cabinet position spring break, the valve cover does not automatically return to neutral position,[link widoczny dla zalogowanych], lost steering servo function. At this point,[link widoczny dla zalogowanych], must be replaced positioning spring (3】 steering wheel rotation, can not return to neutral position to start the engine, the driver moves the steering wheel without rotation, led to a shift failure. This failure occurred in the repair or maintenance of steering gear off and re-open assembly the rotor and the relative position of linked devices installed wrong, causing confusion between steering with oil. reassembled linkage device. the linkage device mark on the splines align the mark on the rotor splines. If there is no mark,[link widoczny dla zalogowanych], the top of linkage call off the center line should be aligned with the rotor slot any teeth in the concave center line. (4) ① steering wheel shaking a serious mechanical failure. such as connecting pins and connecting pin seat of the question, the gap increased wear, steering wheel bearings wear. By examining the clearance and replacement parts to restore the system normal operation. ② steering cylinder with air. the fuel tank side of the port connector loosen, turn the steering wheel, steering to the steering cylinder to loosen the joints without a cavity filled, until the release of the joints are not exposed to fluid flow only when the bubbles, then tighten the fittings. (5), mainly due to the steering wheel rotation is not dead in two-way diverter valve malfunction or a buffer cylinder piston ring damage. replace the oil piston ring; check the bidirectional buffer valve, valve core and valve seat so tight junction station. (Shihezi City Farm Machinery Training Station Lin Hui) single function are included. whether the body make, specifications, models. pay attention to different machines type of timber on the different manufacturers. If the size of pipe wall thickness, metal thickness and so on. (4) purchase when purchased in person inspection ① check whether a table format film machine card, instructions and other relevant technical documents; ② Check the accessories and spare parts are complete random tools; ③ request purchase invoice, manufacturer contact information and service to understand the situation. (5) should pay attention to the technical performance of plastic film machine ① northern regions should be used in plastic film machine plastic tube before the configuration of the triangle earth-moving device, pay attention to the depth adjustable bulldozing bulldozing plate, there must be sufficient strength ② machine Bunch device is a key component of film, working especially fine, pay attention to whether the shape Ischaemum Ischaemum and fixed rules, is there burr,[link widoczny dla zalogowanych], duckbill blade should be sharp, it is best stamping, fixed beak should use 2mm cold rolled sheet, the top of ribs,[link widoczny dla zalogowanych], one soil should be slightly triangular, easy to point people into the soil. Activities Application 2.5mm cold duckbill rolled sheet metal forming, the mouth parts and the duck plate at the stiffener should be. This is not easy to break, Ischaemum should spring, compression spring is best, so easy to clip soil, 50 species of spoon Bunch control access to a small fine, the check kinds of institutions to meet the strict demand, no leakage seeds, Dibble installed after the rack rotating flexible, reliable sealing, special attention must be enough weight, unit weight than the best in the 13kg. ③ larger diameter casing flower field, metal should be thick, 2ram as well, when the diameter is best for the clay, 400mm, earth leakage gap should be adjustable and have a knock soil device. ③ ditching the best use of manganese steel manufacturing wafer diameter 250ram, secondary wafer diameter casing the best in the 250 ~ 300ram, best of all discs are dual bearings, seals should be set bearing seat. ⑤ laminated conical wheel is best, but also with bearings, seals. ⑥ all rotating parts Butter should be set mouth. ⑦ second best single wafer floating casing and equipped with a pressure spring. ⑧ wheel to be heavier repression, general 3kg or so, to bring the best leather, so hard clay.
