Reasons for the adverse problems of the fruit fresh-keeping cabinet and treatment plan
With the use of fruit storage cabinets, people have paid special attention to the problems of compressors in the problems of fruit storage cabinets. During the long-term operation of compressors, there will be some wear and bad problems, we will Solving these problems and wear and tear, if you do not pay attention to these problems, can cause significant losses.
Common unhealthy phenomena: insufficient exhaust
The reason and treatment plan:
The displacement of the refrigerator is based on the volume of the compressor. Mainly can be considered from the following aspects:
a. The compressor running speed of the fruit fresh-keeping cabinet is reduced to reduce the exhaust volume: the fresh-keeping cabinet is designed according to certain data requirements because it is used on the plateau exceeding the required data. When the hand pressure is affected, the suction pressure is lowered and the displacement is reduced.
b, the stuffing box is not strict, resulting in air leakage to reduce the gas volume. The reason is that the stuffing box itself did not reach the normal standard at the time of production; in addition, during the installation, the piston rod and the stuffing box center are not well centered, and there is wear and tear, etc., causing air leakage; usually, the lubricating oil is injected at the stuffing box. It has the purpose of lubrication, sealing and cooling.
c. If the components are seriously worn, exceed the standard, and the gap is increased, the leakage will also increase, thus disturbing the displacement. In the case of normal grinding, it is necessary to replace consumable parts such as piston rings when found.
d, the bad phenomenon of the air intake filter: fouling gambling, resulting in reduced exhaust volume; the size of the suction pipe will change the suction resistance and affect the gas volume, it is necessary to regularly check the fruit preservation cabinet.
e. The spring force of the valve and the gas force are not good. If the spring force is strong, the starting speed of the valve plate will be slowed down. If the spring force is too small, the valve piece will not be able to close. This not only disturbs the displacement, but also may increase the power and the service life of the valve disc and the spring. It can also interfere with changes in gas pressure and temperature in the fruit storage cabinet.
