Standards and precautions for the use of laundry equipment
Voltage is an item that must be paid attention to in the production of every electric equipment. According to national regulations, when the washing machine is under the rated load of 380V and 50Hz, when the power supply voltage is reduced to 85 of the rated value, the motor and electrical parts should be able to start and operate normally.
The washing machine often generates some noise when washing clothes. When washing and dewatering, the sound power and noise of a conforming washing machine should not exceed 75dB. The noise of 63dB is the national A-level level, the noise between 63 and 67dB is the B-level level, and the noise is between 67 and 71dB. The noise between 71 and 75dB is the C level, and the noise between 71 and 75dB is the D level. At present, there are some noiseless laundry equipment in the market. It is believed that in the future, the noise of washing machines will be controlled to a smaller range.
According to the requirements of national standards, the washing machine logo should be clear and clear, durable, indicating the large weight of the washing fabric, the rated dehydration capacity, the high allowable water level and other values; the washing machine structure should prevent people from touching the live parts, and the live parts must have protective measures. And use reliable insulating materials for isolation.
The washing machine that meets the above conditions is the washing machine of qualified quality. Understanding the standard specifications of laundry equipment can help consumers eliminate those unqualified and inferior products when purchasing laundry equipment, and purchase qualified products that are truly assured.
So what should be paid attention to in the process of operation, let us summarize the following points.
1. are mainly used in electric wire hotels, hotels, hospitals, and schools. Of course, many hotel laundry rooms use electric heating washing machines, dryers, ironing machines, etc. These devices are characterized by high power. Everyone knows that the greater the power of the device, the greater the current, and the thicker the wire required, because the cross-sectional area of the wire is proportional to the current passing through the wire. When debugging the equipment, the commissioning personnel should carefully check whether the wires are thick enough and meet the requirements.
2. When debugging the washing machine, be sure to maintain sufficient capacity for the linen in the washing machine, such as 100KG washing machine, fill the linen as much as possible, and ensure that there is 80-90KG linen in the washing machine drum. If the linen in the washing machine is insufficient or there is no linen, debugging cannot be performed. It is possible that when the washing machine is idling, the stability is very good and the machine will not shake. When the linen is actually washed, especially in the washing machine, the shaking of the washing machine is very severe. This is because the linen in the drum of the washing machine is insufficient during debugging.
3. Check the boiler steam in detail. The boiler steam mentioned here is the steam supplied to the laundry equipment, and whether the pressure reaches the required 0.4-0.6kg. At the same time, the steam inlet of the washing machine and the steam inlet of the dryer radiator should be checked. Check carefully at the rotary joint of the ironing machine to see if there is any air leakage.
Basic knowledge of washing machine maintenance:
The washing machine cannot be started: the power is turned on, the phase is missing, the emergency stop switch is not reset, the door control signal is not activated, the controller is caused, and the transmission belt is loose;
Can not heat or add water: control temperature setting, solenoid valve action, valve opening, compressed air, steam, water source;
Inverter overheating: ventilation, voltage, cooling motors, bearings;
Excessive vibration: linen placement, water level, uniform distribution, drainage, super shock switch, shock absorber;
Abnormal sound of the spindle: lack of lubricating oil, loosening of the spindle tightening nut, and bearing wear;
Water leakage at the door: the washing machine door is not closed in place, the seal is damaged, and the door lock device is loose.
