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;
???????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 enough to maintain insurance, the number of hydraulic oil. Cleanliness of the hydraulic oil pump pressure fluid, high life expectancy longer apply.
????2, hydraulic piston bearing the heaviest axis is to support member unit, assuming the bearing clearance occurs, you can not pump fluid within the Department of friction normal space permits three pairs, also deputy rub together all bad break The hydrostatic bearing oil film thickness, reduce the number of bearing shaft pump plunger used to make a life. According to data supplied by the pump manufacturer are flat bearing axis, using life expectancy is 10000h, but also to go beyond this need to change the value of the new port. To the axis of the discharge under split bearings, no professional inspection equipment is unable to check the bearing axis gap swim out, can only use visual, such as found in the table change or roller marks marked with pale, it must be replaced. In more should, when bearing axis change note bearing the letters and the type of the original column are large selection of plunger shaft bearing large load bearing capacity, the best gauge of the original acquisition of the former grid, home plant products, assuming that the replacement of another brand, Please bearing axis due to the experience of teaching staff look-up table on the exchange, the intent is to uphold the like of fine grade and load capacity of the bearing axis.
Fixed displacement due to construction constraints, usually only for that gear pumps use the constant flow of hydraulic source. However, the attachment into the threaded connection on the progress of its planned combination valve function, decrease system cost and system reliability of progress is useful, therefore, the gear pump function can come near the price of expensive, messy piston.
