The decoration industry experts took the solid wood floor as an example, and made a small kick to "snap" some of the bad wood flooring businesses: If the floor area of ​​a certain industry is 80 square meters, and the medium-priced solid wood floor is about 250 yuan per square meter, the total floor price is 20,000 yuan. According to the general specifications of the floor on the market today, the calculation is 0.081 square meters (0.9 meters × 0.09 meters) per piece, then each floor is about 20.25 yuan. If you pack 12 pieces in each box, you need 82 boxes of floor to install 80 square meters of floor. In the actual installation process, the “sucking†method adopted by the unscrupulous wood flooring merchants is to randomly extract a floor from 82 boxes of floorboards, that is, to turn 12 blocks per box into 11 blocks per box. As for the 10 boxes or 20 boxes in the 82 boxes, "this depends on the degree of blackness of the sales staff," the expert said with emotion. If the above floor is taken out 10 pieces, that is to say, the owner is "stealed" by 200 yuan. On average, the floor merchants sell 3 households per day, which is 240 square meters. Floor sales merchants can “steal†600 yuan per day. If calculated according to the annual turnover of 330 days, in addition to the normal profits, these unscrupulous floor businesses can "steal" nearly 20 million yuan from the owner's floor every year, the value is equivalent to "a Passat". It is not difficult to see that these bad wood flooring merchants secretly extract a certain proportion of wooden flooring according to the so-called "convention" in the industry, which is undoubtedly equivalent to stealing money from the owner's pocket. - Hydraulic Diaphragm Metering Pumps 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/refineries hydraulic metering pump/Hydraulic Diaphragm Metering Pumps 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.
