The cause of failure is:
(1) Baotou beiben heavy truck parts of the air compressor intake valve plate drop or pad of a foreign body, close lax. The phenomenon is to touch the inlet by hand, the temperature is higher, exclusion measures are: the removal of foreign body, the valve plate is mounted on the back. If the valve plate is deformed or damaged, replace the new.
(2) the exhaust valve piece is loose or broken. The valve plate is broken or can not be opened completely, and the surface temperature of the air compressor is very high.
(3 Baotou beiben heavy truck accessories) air compressor cylinder pad flush, leakage. Cylinder gasket should be replaced.
(4) Baotou beiben heavy truck parts of piston ring and cylinder wear, or broken piston ring, cylinder. The piston ring and cylinder liner can be replaced according to the situation.
(5) air compressor gear slip. Air compressor gear and shaft is to taper and high torque by pressing to torque transmission, no keyway, slip the reasons for fastening nut loosening caused by torque enough. It can be installed on the fastening nut tightening torque is 200 ~ 300Nm.
The judgment method of press gear slip is hard to withstand the piston (upward), the flywheel disc, piston compressor will be bearish upward, such as movement, the gear has slip.
(6) when installing the cylinder head mounted against the inlet into the exhaust, reverse pump. In the inlet and outlet of the air compressor cylinder head casting marked “S” for “D” for the air intake, exhaust port. Should be removed to re install.
(7) the partition wall of the inlet and outlet chamber is perforated and communicated. Replace the cylinder head.
(8) the pressure regulating valve cup rupture, with the continuous “Chi Chi” leak sound card; or the piston in the key slot, cannot create pressure. Need to change the leather bowl assembly, cleaning pressure regulating valve.
(9) pressure regulating valve to adjust the pressure is too low, or adjust the pressure of the spring break. Screw the adjustment screw to 8bar with a screwdriver, the pressure regulating valve begins to exhaust to the atmosphere, or replace the adjusting spring.
(10) from the air compressor outlet pressure regulating valve to the pipeline leak, “Chi Chi” sound, should replace the connecting pipe.
(11) the air pressure indicator circuit fault or failure. The braking performance is not affected, the normal. Pressure gauge should be replaced.
