VIBRATION ANALYSIS OF A VERTICAL AXIS DRUM BASED WASHING MACHINE Churnika N. Narkhede1, Dr. K.K. Dhande2 S.P.Pune University, DYPIET,Pune nikki.narkhede@gmail.com Received xx/xx/xxxx; Revised xx/xx/xxxx; Accepted xx/xx/xxxx Abstract— Today, there is a rapid increase in the demand for saving energy in all industries and industrial applications and even in home appliances such as microwaves, refrigerators, air conditioners, power tools, vacuum cleaners and washing machines. In a fully automatic washing machine, an unbalanced mass of clothes in a spin drum can cause vibration problems. This causes not only wastage of energy but also noise and structural damage. Each time a washing machine enters its spin cycle, it begins to create high frequency vibrations. The unbalanced mass of clothes causes vibration because in the spin drying stage, the drum spins at a relatively high speed causing the clothes to be pressed against the inner wall of the spin drum and this can become a large unbalanced mass until the end of the stage. This paper focus on the study related to analysis and design of a control system for the …show more content…
Not only that but demand for energy saving is increasing rapidly in all industries and industrial applications and even in home appliances such as microwaves, refrigerators, air conditioners, power tools, vacuum cleaners and washing machines. A number of different parts which are used in a number of different ways can be found inside a machine. But the main goal is to have each part working correctly, cohesively and safely. If a machine is off balance or is vibrating more than it should, not only could it cause damage to the parts inside of it but also to the floor that it is sitting on. Reducing machine vibration reduces the damages that can be seen in the machines and the surrounding area while maximizing the working
wear smooth, certainly the machine will wear out. If the injustice has a spring, or a pulley, or a rope, or a
From the computations above, it is clearly illustrated that there is a disparity between the loading of the boards into the machines and the output of the cleaning and the coati...
The Car Wash industry began to start and grow across the U.S. after the conclusion of World War II. America’s economic rebirth and prosperity created a boom in the housing and automobile industry. What began as a business to satisfy Americans’ love of the automobile has grown over the past several decades into an international industry. From washing one’s car in the driveway with a water hose and bucket of soapy water, to the do-it-yourself, unattended coin operated high-pressure wand locations, to today’s professional car washing businesses which feature complex automatic equipment and technological systems to wash cars more safely and effectively than ...
In this approach, the focus will be on the internal control objectives so that the control design can be well assessed. First, the auditor will define the control measures and objectives and then find out which measures already installed meet the objectives (Tyrer, 1994).
Energy efficient motors use more copper and iron than regular motors. They also consume less energy than regular motors.
The dehumidifier helps reduce the amount of moisture and creates dry air of a certain area that this machine is being placed in, so this means that it can be used in many cities that are close to the equator. So the main issue which this technology can solve, are moist environments. And humid air can usually create moulds to grow on walls, and eventually make a person sick.
Given that organization need control so that they can effectively operate in today’s competitive market, hence they need to determine if their goals have been met, and weather correct actions have been taken. Hence the control process is beneficial in terms of providing and guiding the organizations with adequate regulation of the company’s activities so that they can efficiently focus on the performance of the company. As a result the scope of the process control in an organization is to help the organization in adopting the changes, as the control system will help in anticipating while monitoring and responding to the changing environmental conditions.
In sum, for the reasons described above, the cleanliness of their environment of CNC machine tools is extremely important. Regions of the bench axis motion must be clean and enough fat. If necessary, cleaning should be done on and off the simple reason that otherwise the counter with long downtime is inevitable.
Reheating furnaces and primary rolling mills so that can reduce consumption of power in process
The speed of the motor relies on the number of poles, frequency and slip. The speed equation is as follows: N = 120f/p (1-S). Where f is the supply frequency, p is the number of poles, s is the slip. So the method of controlling the speed is reliable on these factors, and the methods can be one of the methods introduced:
The purpose of this report is showing how to apply the control process in the
The equations of motion form the basic building blocks for any system under consideration. These equations should be formulated as accurately as possible to model the desired system. The δinaccuracies in formulating these equations could result in faulty behaviour of the system which could be very difficult to understand. However, modern control systems are designed to accommodate model inaccuracies to a certain degree. It is very important to ensure that our model is modelled within this range. Errors could also enter the system during the calculation stage due to the precision and number of digits used to represent the values.
A washing machine conjointly referred to as a laundry machine, garments washer, or simply washer could be a machine to scrub laundry, like clothing. The term is generally applied to machines that use water because the primary cleansing resolution critical cleaning. All laundry machines work by using mechanical and thermal energy.
Washing machines have become the most popular mechanical device throughout all modern times. “For thousands of years, one of the most tiresome household tasks was the washing of clothes and lines” (Field Enterprises Educational Corporation 45 ). Washing machines are greatly needed in everyday life. Much labor and has been relieved due to the wonderful invention of the washing machine. The washing machine is also a major time saver. Washing machines have developed proficiently throughout all the years and are still developing day by day. From the wash board to the electric washing machine, laundry has truly been transformed in America, as a result, cleaning laundry is nearly effortless.
It is reasonably simple to draw positive conclusions on the washing machines impact, and I will explain some of those. There has also been some negative effects and some interesting social change regarding cleanliness standards.
