Range of refrigeration unit used in cold storage installation made more widely, construction seafood pool is also very wide, in the use of the process, refrigeration units will inevitably fail, here are eight kinds of common faults refrigeration unit:
First, the refrigeration unit pressure is low. When the actual gas consumption is greater than the output gas volume of the refrigeration unit, it will cause the deflation valve failure, the intake valve failure, the hydraulic cylinder failure, and the load solenoid valve failure. The above failure will cause the pressure switch to malfunction. .
Second, the temperature of the exhaust of the refrigeration unit is higher, possibly because the liquid level of the coolant in the refrigeration unit is too low; the oil cooler is dirty; the oil filter core is clogged; the temperature control valve is faulty; the oil cut solenoid valve is not energized or The coil is damaged; the diaphragm of the oil-disconnecting solenoid valve is broken or aged; the fan motor is faulty; the cooling fan is damaged; the exhaust duct is not smooth or the exhausting resistance is large; the ambient temperature is outside the specified range; the temperature sensor is faulty; the pressure gauge is faulty.
Third, the refrigeration unit has high fuel consumption or compressed air with large oil content and too much cooling dose. The correct position should be observed when the refrigeration unit is loaded. At this time, the oil level should be no more than half; the return line is blocked; the installation of the return line does not meet the requirements. When the refrigeration unit is running, the exhaust pressure is too low; the oil separation core is broken; the internal separator of the separation cylinder is damaged; the refrigeration unit has oil leakage; the coolant is deteriorated or overdue.
Fourth, the refrigeration unit exhaust pressure is too high, the intake valve is faulty; hydraulic cylinder failure; load solenoid valve failure; pressure setting is too high; pressure sensor failure; pressure gauge failure; pressure switch failure.
Fifth, the refrigeration unit has a large current, the voltage is too low; the wiring is loose; the refrigeration unit pressure exceeds the rated pressure; the oil separation core is blocked; the contactor is faulty; the main unit is faulty; the main motor is faulty;
Sixth, the refrigeration unit can not start, the fuse is broken; the temperature switch is broken; the wiring is loose; the main motor thermal relay operates; the fan motor thermal relay operates; the transformer is broken; there is no power input; the fault is not eliminated; the controller is faulty.
Seven, fan motor overload, fan deformation; fan motor failure; fan motor thermal relay failure; loose wiring; cooler blockage;
We are Manufacturer and Supplier to offer modular plugs in standard configurations to terminate modular cords for patching or work area applications. Our Modular plugs can be terminated to the exact cable length needed in order to maintain a neater, more organized installation. The modular plugs terminate twisted-pair cable with 26 - 22 AWG (0.40mm - 0.64mm) solid or 7-strand conductors with an insulated conductor diameter of 0.86 - 0.99mm (0.034 - 0.039 in.). All modular plug contacts have 50 microinches minimum of gold plating over nickel and meet TIA-968-A and IEC 60603-7 specifications.
Modular Plug is the name given to a family of electrical connectors originally used in telephone wiring and now used for many other purposes. Many applications that originally used a bulkier, more expensive connector have now migrated to modular connectors. Probably the most well known applications of modular connectors are for telephone jacks and for Ethernet jacks, both of which are nearly always Modular Connectors.
Modular Connectors were originally used with the registered jack system, which precisely describes how the connectors are wired for telecommunications. The registered jack specifications define the wiring patterns of the jacks, not the physical dimensions or geometry of the connectors of either gender. Instead, these latter aspects are covered by ISO standard 8877, first used in ISDN systems. TIA/EIA-568 is a standard for data circuits wired on Modular Plug&Connectors.
