When replacing the bearing, should pay attention to the type of original letters and bearing, mostly piston bearing use large load bearing capacity, the best acquisition of the former factory, the original specification of goods, assuming replacement of another brand, you should seek advice on the bearings resume The staff look-up table on the exchange, the intent is to uphold the level of accuracy and load bearing capacity.
Selection charge pump supply piston pump, the use of 3000h, the operator need 1-2 times a day on the piston view, dynamic view of the hydraulic pump is not a normal job. Found cylinder speed drops or stuffy car, you should pump up the collapse of view, is not a view of the impeller edge scratching appearance, internal gear pump room is not too large. For self-suction-type piston pump, the hydraulic oil tank must not fall below the lower limit of the oil standard, should adhere to meet the amount of hydraulic oil. The higher the cleanliness of hydraulic oil, the use of the longer life expectancy of the hydraulic pump.
Piston length of life using the number, and the usual protection protection, quality and quantity of hydraulic oil, oil cleanliness and so on. Avoid the oil particles on the piston friction and wear vice constitute an effective way to extend piston life expectancy is. Repairing parts replacement should try to use the original production of parts that sometimes more than other parts of the offer imitation expensive, but the quality and stability is better, assuming that offer cheap imitation parts, seems to be cost savings in the short term, but thus bringing out the risks, it may pose a greater use of piston damage.
The main component is a piston pump bearing, assumed bearing presents clearance, there is no guarantee internal pump three vacancies on the normal friction pairs together can damage the hydrostatic bearing oil film thickness of each friction pair, down piston pump bearings use life expectancy. According to the hydraulic pump factory supplied material, even using the number of bearing life for 10000h, this value would need to be replaced over the new port. Open bearing down, no professional view instrument is unable to view the bearing clearance, the only use visual, such as found in the roller surface scratches or discoloration, it must be replaced. Valve plate has a plane equipped with a flow and spherical flow two ways. Deputy spherical friction with the flow in the cylinder with a relatively shallow stream surface scratches after polishing method of correction; cylinder with flow surface grooves deeper, should be the choice of "surface engineering technology" approach to fill the trench, then grinding , not blindly grinding ,, to prevent copper layer thinning or spill out of the steel substrate.
?Before using the high-pressure pumps to clear the pipeline should pay attention to what?
????1, between the high-pressure oil pump pipe cleaning, we must first check the nozzle, the nozzle to ensure that it does not appear the phenomenon of clogging.
????2, during the cleaning and construction time, we need to pay attention to is the location to place the nozzle. Usually the nozzle should pipe approximately 30 cm into place, and then the pressurization of the nozzle, the nozzle is fed into the pipeline which, in this position the placement and pressing operations are very important.
????3, after completion of the cleaning work, we have even pulled out of the nozzle from the pipe, in order to avoid nozzle swinging staff harm, should the pressure of the high pressure pump to zero as soon as possible.
????Spunlace use high-pressure pump:
First, the medical aspect
Disposable surgical gowns, surgical cover cloth, surgical cloth, surgical aprons;
Wound applicator material, bandages, gauze, Band-Aid and the like;
Second, clothing such as garment interlining, baby clothes, training clothes, carnival night-time color clothes, all kinds of protective clothing such as gowns and the like;
Third, the wipes category such as a home, yourself, beauty, industrial, medical and other dry wipes;
??Fourth, the decoration cloth such as automotive interiors, home interior, stage decoration;
