Furniture is the protagonist of home decoration. Its versatility and practicality determine its price, so people can't change furniture often, so its maintenance is especially important. In summer, the temperature is high, the humidity is high, the furniture is maintained and the summer decoration pollution is avoided. The experts gave some suggestions to remind the public to pay attention to the maintenance methods of summer wooden furniture.
Changes in moisture content tend to cause deformation of the wood, so care is especially needed, especially during this hot summer. For example, the sun can not be directly exposed for a long time, not too cold or too hot, too dry and humid environment is not suitable for solid wood furniture. If the temperature and humidity change is too large due to frequent switching of the air conditioner, even the qualified solid wood furniture products sometimes undergo deformation and cracking. However, in fact, if the furniture used is well-treated wood, the normal summer climate will not have much impact on it.
Today, most branded furniture processes moisture first. Professionals said that many furniture use solid wood in the stressed part and high-density board in other parts, in order to prevent seasonal expansion and contraction. Even if the humidity in the summer rises relatively, the wood will only expand slightly, and these natural changes will not affect the durability of quality furniture. However, if you choose Chinese traditional mahogany furniture, because this kind of furniture has a lot of carvings, and most of them have not been treated with moisture content, the first year of use needs to be reworked and polished.
In order to extend the life of the furniture, in the summer, it is necessary to prevent excessive changes in temperature and humidity and strong illumination. Experts advise consumers to keep furniture away from heat sources or air conditioning vents to avoid large temperature differences that can damage or prematurely age furniture. At the same time, the position of the furniture can be adjusted to avoid direct sunlight, and if necessary, cover with curtains. Solid wood drawers and sliding doors may be difficult to open and close due to excessive expansion. You can apply wax or paraffin on drawers, sliding door edges and bottom slides.
As
the name suggests, diaphragm metering pump using a special design and
processing of flexible diaphragm instead of the piston, under the action
of the drive mechanism to achieve reciprocating motion, complete the
suction - discharge process. Due
to the segregation of the diaphragm, the isolation between the metering
fluid and the driving lubrication mechanism is realized in the
structure. High-tech structural design and the selection of new materials has
greatly improved the service life of the diaphragm, coupled with
excellent corrosion resistance of composite materials, diaphragm
metering pumps become the main application of fluid measurement pump
type.
In
the diaphragm-type metering pump family members, the hydraulic
diaphragm metering pump as a result of the use of hydraulic oil evenly
drive the diaphragm, to overcome the mechanical direct drive mode under
the pump diaphragm too concentrated shortcomings, to enhance the
diaphragm life and working pressure ceiling. In
order to overcome the single diaphragm metering pump may occur due to
damage caused by the diaphragm damage, and some metering pumps equipped
with a diaphragm breakage sensor to achieve the diaphragm when the
automatic chain protection; with double diaphragm structure of the pump
head to further improve its safety Sex, suitable for security protection is particularly sensitive to the application.
As a kind of diaphragm type metering pump, the electromagnetic driven
metering pump generates the pulsating driving force with the
electromagnet, which saves the motor and the speed change mechanism,
makes the system compact and compact, it is an important branch of the
small range low pressure metering pump.
Precision metering pump technology has been very mature, the fluid metering capacity of up to 0-100,000l / h, working pressure up to 4000bar, the scope of work covers all areas of industrial production requirements.
