Found at the scene of the spill point in both sides of the pressure pump hinge base and the junction of the threaded sleeve, hinged seat and at the connection of the threaded sleeve, as well as plug and threaded sleeve junction

, Then observe the pressure gauge, oil pressure is normal. The O-ring seal is damaged, combination washer disassemble pressure oil pump and put new seals

, The beginning of oil spills, running about 15 minutes, the original spill point and oil spills, and so repeatedly china solenoid valve ; What is more, a user-site pressure oil pump

The pump body turned out to be near the hinge base fracture.

Through observation, research, discussion, and found that the long spring hinge base, so that when the hole drain plug screwed into place, the spring is compressed over

Deformation, the gap between the turns is too small, the preload is too large, so that the check pneumatic accessory (ball) the opening pressure is too large, the opening is too small, the steel ball and

Ball between Block crevice flow - press ure characteristics of the steel ball in front of a great pressure, the pressure led to the O-ring and combination washer

Destruction of oil spills. Local stress concentration in the pump body, causing serious consequences of the pump body fracture; gauge shows a gap after

The surface pressure, which shows the value of the pressure value is reduced due to the slits role reason no problem, and therefore single point of view from the pressure gauge.

Repair measures the hole drain plug screw up, remove the spring and truncated appropriate length (approximately truncated half) and replace it with a new O-ring

And combination washer broken pump body also needs to be replaced, and then reassembled attention to cleaning these parts, assembly, The system is to prevent pollution. This

Kind of repair, no oil leakage, the system is operating normally.

Effect, according to the observation of the scene, before restor ation daily about oil spills 0.5kg, roller press extrusion barrel roller bearing grease value (about

180kg) of about 10,000 yuan, oil spills loss of about 830 yuan a month; repair oil spills, no longer significant economic benefits.

More importantly, since the pump is a metering pump system to bearings for the grease, oil spills amounted to less than the original design requirements, ie

The sufficiently lubricated bearings can not get to the long run, will reduce bearing life, increase the cost of operation and maintenance; bearing lubrication in good condition after the repair

, To ensure normal use of the bearing, extending the bearing life.
