Knowledge!common faults of refrigeration and air conditioning equipment
There are five substances in the refrigeration system cycle: refrigerants, oil, water, air, and other impurities. The first two are necessary for the normal operation of the system, while the other three substances are harmful to the system but cannot be completely eliminated. At the same time, refrigerants also have three states: vapor, liquid, and gas-liquid mixture. Therefore, once the air cond...
Knowledge! Multi-stage centrifugal fan performance
Technical performance 1. The fan is equipped with a base, and the fan and motor are assembled on the same base. 2. The blower base, without anchor bolts and with 8 rubber shock-absorbing pads, is placed directly on the ground for easy construction. 3. Complete fan accessories. Including base, transmission device, inlet and outlet mufflers, pressure gauges, safety valves, elastic joints, check val...
Knowledge! Main components of multi-stage (casting) centrifugal blower
1. Host 1) Fan: The design and structure of the blower are sturdy and durable, simple to maintain and easy to control. The casing is made of cast iron HT250. It adopts an external bearing structure, in which the impeller is installed on a high-strength main shaft and supported by anti-friction bearings. Bearing design life is at least 30,000 hours (4 years). The fan has a scientifically designed r...
Knowledge!Common faults of fan coil units
small air output and high noise, temperature deviation, water leakage, and motor does not rotate. 1. The air output of the fan coil is small and the cooling capacity is poor: When the fan is running normally, in addition to the small air inlet volume and air duct leakage, air duct leakage rarely occurs and can be easily dealt with. The small air inlet volume is often caused by the blockage of th...
