Cabinet hardware now plays a very important role in the kitchen. The quality of kitchen hardware also determines the overall function of the cabinet and the quality of the product. Therefore, when choosing a cabinet, consumers should not only pay attention to the quality of the cabinet and the countertop, but also the cabinet. The quality of the hardware. 1. Skirting board The skirting board is a relatively sma

At present, the muffler is mainly divided into the following types: Resistive muffler, also known as absorption muffler, uses sound-absorbing materials to absorb noise. The sound-absorbing material has a loose and porous structure. Sound waves enter the pores and cause small vibrations. Due to friction and viscous resistance, a considerable part of the sound energy is converted into heat and is absorbed. The re

In a closed space such as a room or a sound insulation cabin, ventilation and heat dissipation are often required, and it is necessary to design an opening or duct for air exchange with the outside in the indoor space. The opening or the air duct not only realizes the airflow exchange between the indoor space and the outside, but also forms a channel for sound propagation with the outside. In order to ensure the requ

In the machinery industry, the normal operation of machinery will produce a lot of noise. In order to create a more user-friendly working environment, mufflers have come into being. What types of mufflers are there? Today we will share the relevant basic knowledge for your reference. Types of muffler: There are many types of mufflers, but according to different muffler principles, there are resistive mufflers, res

1. Resistive muffler The resistive muffler uses the sound-absorbing material or sound-absorbing structure arranged on the inner wall of the tube, and relies on the pores of the sound-absorbing material to cause the sound wave to cause air and material vibration in it to generate friction and viscous resistance, and convert sound energy into heat energy. Absorption, so that the noise propagating along the pipeline

Since the muffler is installed on the equipment, it also allows the air to flow smoothly while silencing the sound, so there is a comprehensive performance requirement. basic requirements: Muffling performance: Under normal working conditions, there is a sufficiently large amount of muffling in the required frequency range. The amount of noise reduction is divided into the amount of dynamic spectrum noise reductio

ARO, an Ingersoll Rand brand, has introduced new conductive polyvinylidene fluoride (PVDF) pumps in the ARO EXP diaphragm pumps range Showcased at the recent Hannover Messe Pump trade fair, the 1- and 2-inch pumps are the latest addition to the EXP range of process and automation-ready diaphragm pumps. They are designed for fluid management involving highly corrosive fluids transfer in hazardous duty environments
