Disassembly and inspection process of constant temperature and humidity test chamber
Recently, some customers responded that “the constant temperature and humidity test chamber has been used for a long time, the compressor is a bit problematic, and I want to know the specific repair methodâ€. For the totally enclosed compressor unit, it is compact and compact, and it is assembled and assembled. Special attention should be paid to its methods and procedures.

The compressor and the motor are combined and placed in the same constant temperature and humidity test chamber casing, and a certain amount of lubricating oil is charged in the casing, and three lead-out connecting pipes and one electric box are arranged outside the casing, and the shape is round. Shape or oval. Therefore, when disassembling the compressor, pay attention to the correct steps and carefully disassemble, repair and assemble.
Before the compressor of the constant temperature and humidity test chamber is removed, the process tube should be opened with a cutter or scissors to release the refrigerant, and then the pipe is welded or cut from the original assembled pipe joint, and the fixing screw is loosened. Lower compressor. The lubricating oil in the casing can be poured out from the return pipe, and the amount of oil can be recorded as a basis for refueling after repair.
Compressor casing sawing method: It can be sawed by hand or cut by special machine. Before the sawing, the compressor casing should be wiped clean and the repaired displacement marks should be made at the welds of the upper and lower casings of the compressor. When cutting, pay attention to the depth of the cutting to prevent damage to the components inside.
After sawing the casing, do not blindly disassemble the parts inside the machine. Carefully observe whether the exhaust pipe and the suspension spring are broken, whether the compressor seat is rusted, whether the piston is stuck, whether the valve is deformed, and whether the terminal is intact. Whether the winding is burnt, whether the rotor and the piston of the rotating motor are flexible, and whether the suction pipe is unblocked, etc., after the analysis determines the fault location or the faulty part, the repairing is performed to avoid expanding the fault and increasing the workload of the repairing work.
Dismantling of the compressor motor: Generally speaking, the motor winding burns more faults. The stator fixing bolts can be loosened and removed first, the stator can be removed, and the stator windings can be repaired or wound. Before assembling the constant temperature and humidity test chamber compressor, be sure to carefully clean the relevant parts and valves. When assembling, you can reset the components one by one by referring to the reset mark in the reverse direction of the disassembly. The installation of the inner pipe of the exhaust pipe should be careful not to touch the inner casing of the exhaust pipe, so that it is suspended and fixed.
Tips: If your constant temperature and humidity test chamber needs to be disassembled to solve the problem, and you are not a professional, Xiao Bian still recommends that you repair it in time, let the professional technical engineer to help you solve the problem quickly, so as not to cause damage due to improper operation. .
