Increased. Others such as bearing improper assembly, damage. When the shaft and ancillary equipment installed coaxial ultra-poor also make noise to increase. It should be
checked. Replace if necessary.
Hydraulic pump, pump bearings how to check and how to repair!
1. Life hydraulic pump inside the plunger rod and the cylinder bore bearings, sliding shoe and the swash plate, valve plate and cylinder with flow surface normal three pairs of
friction pair gap, but also undermine the friction pair hydrostatic bearing oil film thickness reduce piston bearing life. Use process, to regular maintenance and periodic replacement of
bearings in accordance with the instructions. According to manufacturer data, the average life of the bearing is about 10000h, more than this value will need to be replaced with new
bearings.

2 Bearing Detection
????Bearing test items bearing clearance, bearing clearance to use professional testing equipment to detect, therefore. Repair process, only use a simple visual inspection
methods, such as found in the roller bearing surface scratches or discoloration, you must replace the bearing.

3 Note the replacement of bearings
????When replacing the bearing, should pay attention to the original bearing the letters (representing precision grade) and model used on the piston bearing mostly by
large
Load bearing capacity of the child. When replacing the hydraulic pump is best to buy good quality factory standard specifications. If not able to buy, you need to substitution,
should lookup substitution. The purpose is to keep the level of accuracy and load bearing capacity, otherwise it will affect the results of the pump. Severe will reduce pump life.
YCY14-1B swash plate type axial piston pumps into pressure oil type and from the sucking-two!
1. Pressure oil hydraulic pump used
????Pressure type oil pump pressure tank have mostly used, but also bring up the oil pump itself cylinder to the hydraulic pump inlet to provide pressure oil.
????(1) against the pressure of the hydraulic oil tank after each time you start the machine, have to wait for the air pressure to use the hydraulic reservoir pressure, in
order to speak
For machinery. Such as insufficient hydraulic pressure to operate the machine tank will cause abnormal wear of the pump body board and return the platen.
????(2) the supply of fuel boost pump piston, after use 3000h, work process, the operator needs to YCY14-1B swash plate type axial piston pump check 1-2 times a day, mainly to
check the sound operation of the pump is it normal. Such as the hydraulic cylinder speed drops or stuffy car phenomenon found dealing with the disintegration of the charge pump inspection,
check whether the impeller edge scratches phenomenon, the internal gear pump gap is too big.

2. Since the suction-type pump use
????Self-suction-type pump self-absorbing ability is very strong, no external oil supply. Use should pay attention to often check the hydraulic oil within the hydraulic
reservoir, oil
Not less than the lower limit of the oil standard, to maintain a sufficient number of hydraulic oil.

3. The hydraulic system uses Notes
????Construction machinery use, should pay attention to maintaining clean hydraulic oil pressure line station. Cleanliness higher the hydraulic system of hydraulic oil,
hydraulic pumps
The longer service life.
