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 aspectDisposable 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;???????Fifth, the agricultural class such as heat greenhouses, anti-weed growth, abundance of cloth, cloth and other pest control preservation;Sixth, spunlace composite processing can also be used, it is possible to produce a "sandwich" type construction products, the development of new composite materials more useful.There are many local to watch for. So in accordance with the pressure to pick it, so what's pump selection matters watching it? Today, we look at it together now.Pump selection methods, usually by hydraulic pressure, displacement and driving power to decide.Required pressure (1) hydraulic pressure of the hydraulic pump pressure slightly higher than the executing agency selected the best, China's machine tool profession hydraulic pump is usually calibrated pressure of 6.3MPa or less. For a detailed working conditions are not the same, the selected pressure pay attention to the following situation: 1) according to a certain output power, under the same pressure and flow condition, the volume of the pump or motor should be as small as 2) With increasing pressure, the oil to heat, oil temperature increases, valves and seals. etc. leak increases. 3) high pressure valve and transmission structure will increase, it is difficult to achieve weight reduction and miniaturization of the pump.(2) displacement hydraulic pump displacement based approach to the selection of actuators (hydraulic cylinders, motors) size and load demand.(3) hydraulic pump drive power of resolution, based on the work of the hydraulic pump discharge pressure and useful to determine the oil pump drive power??1, fuel pump method straight axis swashplate pressure cylinder power plugs from the sucking-two oil types. Pressure for large liquid-type oil pump has a pressure tank are selected, there are also supplemented with hydraulic oil with the body of the cylinder inlet port to supply pressure oil pump liquid type oil absorption since. Strong pressure from the sucking pump ability, without external oil supply. If found to reduce cylinder speed or stuffy that should be made, when the car hydraulic pump repair, check the impeller marginal whether existing injury blow is like, the internal gear pump space is not too large. About suction fluid from the inner, cylindrical plunger pressure oil tank shall not be less than the lower limit of the oil standard sufficient
