The environmental performance of the living room floor is better than the "F4 star"

Recently, according to the latest sampling results of the National Wood-based Panel and Wood Bamboo Products Quality Supervision and Inspection Center, the living room multi-layer parquet has passed all the testing items, and the measured value of formaldehyde emission is only 0.2mg/L, which is completely excellent. The standard of F4 star ≤ 0.3mg / L.

The quality sampling inspection was carried out by the State Forestry Administration and commissioned by the National Quality Supervision and Inspection Center for Wood-based Panels and Wood Bamboo Products. The center is a state-authorized national statutory professional inspection agency for wood-based panels, bamboo and wood products and related products. This sampling is mainly for core indicators such as static bending strength, water content, surface wear resistance and formaldehyde emission.

F4 Star is the highest standard for formaldehyde control in household products in Japan. It is also recognized as one of the most stringent standards for formaldehyde content in homes. Achieving the F4 star standard means that the product can pass the most stringent import inspections in developed countries in terms of environmental performance.

Hydraulic Pump

Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). It generates flow with enough power to overcome pressure induced by the load at the pump outlet. When a hydraulic pump operates, it creates a vacuum at the pump inlet, which forces liquid from the reservoir into the inlet line to the pump and by mechanical action delivers this liquid to the pump outlet and forces it into the hydraulic system. Hydrostatic pumps are positive displacement pumps while hydrodynamic pumps can be fixed displacement pumps, in which the displacement (flow through the pump per rotation of the pump) cannot be adjusted, or variable displacement pumps, which have a more complicated construction that allows the displacement to be adjusted. Although, hydrodynamic pumps are more frequent in day-to-day life. Hydrostatics pump which are of various types works on the principle of Pascal's law. It states that the increase in pressure at one point of the enclosed liquid in equilibrium of rest is transmitted equally to all other points of the liquid, unless the effect of gravity is neglected. There are different types of hydraulic pumps as below:

1.    Gear Pumps

2.    Piston Pumps

3.    Vane Pumps
