the bearing temperature and vibration are as follows: Loosen the coupling large, with a horizontal instrument were placed on the electric oil pump shaft and the base, by adjusting the wedge pad, correction unit level, tighten the bolt appropriate to Anti-around. In order to prevent pipeline debris into the pump, to the newly installed pipeline should be installed in the pump glue filter, the effective cross-section should be greater than 2 to 3 times the suction pipe section.??The main component is a piston pump bearing, if the bearing clearance occurs, you can not ensure normal internal pump three pairs of friction pair gap, but also the destruction of each friction pair hydrostatic bearing oil film thickness, so that the piston pump bearing reduced service life. According to information provided by the manufacturer of the pump, even bearing service life of 10000h, above the top of this he will need to exchange a new port value.Dismantled bearings, no professional testing equipment is unable to detect the bearing clearance, can only adopt the visual, such as roller scratched or discolored appearance of situation, it is necessary to replace.When replacing the bearing, it should pay attention to is the original English words bearing the mother and model, piston bearing most receiving large load bearing capacity, it is best to purchase the original factory, the original specifications of the product, if the exchange another brand, you should seek advice on bearing history lookup swap staff, in order to allow precision grade and load bearing capacity can be maintained.????Piston length of life, and the usual maintenance, number and quality, such as hydraulic oil clean-up of oil-related. Stop the oil particles to cause piston friction pairs wear, but also extend the life of the piston favorable way.Replacement parts in the repair should as far as possible with the original production of parts that sometimes imitation parts than other more expensive, but the quality and stability is better, if the purchase price of cheap imitation parts, feeling short term cost savings, but the resulting potential problems, but also on the use of piston cause more damage.????Oil in the form of a straight axis swashplate piston pump based????Straight axis swashplate piston pump into pressure from the sucking oil type and type two. Most oil pressure hydraulic pump with a pressure tank there, but also comes with its own pump to pump up the oil cylinder oil inlet supply pressure of the oil. Since self-absorbing capacity type hydraulic pump super suction, no outside help to supply.????After the required pressure of the hydraulic oil tank, after each time you start the machine, you have to wait to use the pressure of hydraulic stains box before they can start operating machinery. Once the hydraulic reservoir pressure is insufficient, served as the machine will pump and slip inside the whip phenomenon caused by the pull-off, then the cause is not normal wear and tear the body board and return the pump platen. After using the charge pump supply piston pump 3000h, operators need to check piston 1-2 times a day to check the pump operation is not a normal sound. If the cylinder speed drops or stuffy car situation, you should check the disintegration of the charge pump, check the impeller edge if there are scratches phenomenon, the internal gear pump gap is too big.For self-suction-type piston pump, the hydraulic oil tank must not fall below the lower limit of the oil standard, to maintain a sufficient amount of hydraulic oil. Cleanliness of hydraulic oil higher, longer pump life.View high-pressure pump job before the job is as follows:Before 1 primary electric pump equipment using first check the voltage status, and plugs, sockets to see is not connected;2, one end of the high-pressure pipeline, links on the electric pump device connector, the other end connected to the needs of the things;
