I. Introduction

Industrial washing machines are electrical equipment used for washing large quantities of clothes in hotels, hotels, laundries or factories. The washing process is generally composed of water inlet, forward washing, pause, reverse washing, drainage and dehydration. With the rapid development of automation and the continuous improvement of industrial process requirements, industrial washing machines have higher and higher requirements on inverters, which can meet the high starting torque, multi-speed, wide voltage range, automatic slip compensation and fastness of industrial washing machines. Powerful communication methods, etc. And stable performance, can adapt to various complex high temperature and high humidity environment.

Second, the composition and working principle of the fully automatic industrial washing machine

Fully automatic industrial washing machine refers to a large-capacity washing machine that has functions of initial washing, washing, rinsing, bleaching and dehydration, and can automatically switch between the functions without manual operation. Industrial washing machines can be divided into three types: suspension suspension type and water injection balance suspension type, and gravity fixed type according to different ways of vibration reduction and vibration isolation. At present, the mainstream products on the market are suspension type vibration isolation automatic industrial washing machines. It is mainly composed of shell, frame panel, inner drum of main shaft, transmission system, vibration isolation system, front door parts, charging parts, brake parts, water discharge valve parts, super vibration parts, control parts, pipeline parts and pneumatic system.

The working principle of the fully automatic industrial washing machine is: under the unified scheduling management of the timing controller, the asynchronous motor is controlled by the frequency converter to continuously perform forward and reverse rotation to realize the asynchronous movement of water and clothing, thereby causing the water and clothing to rub against each other 、Knead to achieve the purpose of washing.

It mainly has the following washing procedures:

First, add water and wash in forward and reverse rotation for 25 minutes. After washing, drain and enter the dehydration stage. The dehydration stage includes three processes: uniform distribution, medium removal and high removal. Even distribution is in the presence and absence of water. Rotate forward at a higher speed than the washing process for 1.5 minutes to make the clothes evenly adhere to the inside of the drum of the washing machine to make the subsequent dehydration process stable; after draining, increase the speed to enter the medium-speed dehydration process (2 minutes), and then enter The high-speed dehydration process (5 minutes) reduces the moisture content of the laundry to the required level. There are two ways to set the speed:

1) Set the running speed of each stage directly on the inverter in a multi-stage speed mode;

2) The running speed of each stage is set by communication through a dedicated computer for washing machine.

The running speed of each stage is:

Washing: around 7HZ

Uniform: around 15HZ

In the off: 80HZ

High off: 110HZ

3. Advantages of using Ou Lun OD6L series inverter
