GZYB high pressure residue pump usage
The main system of gear main efficiency depends on the volumetric efficiency of GZYB high-pressured residue pump. When the volumetric efficiency drops to 72%, it needs to be repaired, replaced with bearings and aged seals. Clearance pair of friction, so that its performance has been restored.
1, GZYB high pressure residue pump oil supply form
Straight shaft swash plate pressure for the type of self-priming oil pump plug force two. The pressure for large pump hydraulic fluid are used with pressure tank, there are GZYB high pressure residue pump oil fill with this sub-pump to GZYB high pressure residue pump inlet to provide pressure oil liquid oil suction from. Pump self-priming oil capacity is strong, no external oil supply.
After the tank oil starts the machine for a second time, it is necessary to wait for the gear box to reach the back pressure to operate the machine. Such as the gas tank gas load on the time enough not to pressure machinery, will GZYB high pressure residue pump and slip whip made, like now off into the pump will cause the pump body back plate and platen non-mining. Wear often used to fill pump piston pump, use 3000h, the operation on the daily piston pump examination 1-2 times, check whether the GZYB high pressure residue pump is normal sound transmission. If you find the gear cylinder speed decreased or boring should be, when the car disassemble the charge pump check, check whether the edge of the impeller scraping is like, whether the internal gear pump clearance is too large.
For self-priming fluid, the oil in the pump plug-type pressure tank shall not be lower than the lower limit of the fuel oil enough to hold the amount of gear oil required. The more fluid cleanliness of the pump fluid, high service life.
2, GZYB high pressure residue pump bearings
Piston pump is the most important part of the shaft bearing, if the bearing appears clearance, you can not guarantee that the Department of internal fluid pressure card three pairs of normal wear vice, but also Vice-scrub all broken broken gear support oil film thickness , Reduce the piston bearing bearing pump life. According to GZYB high pressure residue pump manufacturer information provided by the bearing shaft, the service life of 10000h, more than the need to change the value of the new port.
Shaft to unload bearing, there is no professional testing equipment is unable to detect gap travel bearing out, can only be used for visual inspection, such as roller table change or mark scratching look, it must be replaced.
In the more should be replaced when bearing bearing the original bearing the English letters and models, the column bearing bearing large bearing capacity with large bearing capacity, it is best to buy the original rules of the original factory products, if the replacement of another brand, There should be a bearing on the experience of teaching staff look-up table swap, the purpose is to maintain the same degree of precision bearing-level and load capacity.
