2. For air-cooled water chillers, poor heat dissipation of the condenser, non-condensable gas in the system, and partial blockage of the refrigeration pipeline may all lead to high condensation pressure and high-pressure alarm.
For water chillers, high pressure refers to the compressor discharge pressure.
What are the reasons for high and low pressure meters and low and high pressure meters of chillers? According to your description, it should be the pump. You can check it.
How to solve the alarm of high pressure in Nagin chiller? Thank you for air cooling and cleaning the radiator.
Clean the shell-and-tube condenser/cooling tower immediately after water cooling;
Poor heat dissipation leads to high voltage alarm.
What is the high pressure of snow in the compressor of industrial water chillers? If the high pressure does not exceed 2.2Mpa, it is considered normal. The high pressure varies slightly with the seasons.
What are the common causes of high pressure alarm of ventilator? The common causes of ventilator high pressure alarm are as follows:
Tracheobronchial spasm and stenosis;
Respiratory mucus retention;
Artificial airway obstruction;
The patient has increased muscle tone, cough or new complications in the lungs, such as pneumonia, pulmonary edema, atelectasis, tension pneumothorax, etc.
The alarm limit of the upper airway pressure alarm is set too low.
In modern clinical medicine, ventilator, as an effective means to replace the function of spontaneous ventilation, has been widely used in respiratory failure caused by various reasons, anesthesia and respiratory management during major surgery, respiratory support treatment and emergency resuscitation, and occupies a very important position in the field of modern medicine. Ventilator is an important medical equipment to prevent and treat respiratory failure, reduce complications, save and prolong patients' lives.
What is the general reason for high-pressure alarm of water chillers? The cooling water flow of 1 is too small or the water temperature is too high (increase the cooling water flow or decrease the water temperature).
2 condenser copper tubes/fins have a lot of dirt, and the heat exchange effect is poor (cleaning or replacing the filter)
3 Too much refrigerant (discharging part of refrigerant) 4 Too small opening of expansion valve (properly adjusting the opening of expansion valve)
Panda, an industrial cold water high-pressure cleaning machine, is one of the earliest enterprises in the cleaning machine (car washing machine) industry in China, and the drafting unit of the cleaning machine industry standard. It has successively won the honors of Shanghai famous trademark, Shanghai famous brand product and high-tech enterprise. The only manufacturer in China covers almost all high-pressure cleaning machines, including household high-pressure cleaning machines, ordinary high-pressure cleaning machines, industrial commercial high-pressure cleaning machines, ultra-high-pressure cleaning machines and so on. Can be purchased through online sales, telephone sales, dealer sales and other channels.
What happens if the high-voltage switch is removed from the chiller? The reason is that the high-voltage alarm has been ringing. The consequence is that the safety valve is re-protected, or the copper tube explodes. Why not replace the high voltage switch?
What happened to the high-pressure alarm of the water cooler of the RF tube laser marking machine? Ma Yin YM 1030 laser marking machine for RF tube of glass tube is cooled by water cooling.
When the water quality becomes dirty, the above phenomenon will occur when the filter screen is blocked.
