SHACMAN High quality AC compressor DZ1642840014

Description

The function of SHACMAN AC compressor DZ1642840014:

The SHACMAN AC compressor DZ1642840014 is a key component of the air conditioning system for Shaqi series vehicles. It is mainly used for compressing and transporting refrigerant to achieve the cooling function.

SHACMAN AC compressor DZ1642840014 .Here is the detailed introduction:

Common models: Shaanxi Auto air conditioning compressors come in various types, suitable for different vehicle models.
For example, DZ13241824121 is suitable for Shaanxi Auto DeLong’s new M3000, SZ915000716 is suitable for Shaanxi Auto DeLong F3000, and DZ15221840303 is suitable for Shaanxi Auto DeLong X3000, M3000, etc.

WORKING PRINCIPLE OF SHACMAN AIR CONDITIONER COMPRESSOR DZ1642840014 :

The compressor receives positive control, but the AC output receives negative control. In the middle, a K8 relay is used in the dashboard wiring harness to relay the control. Its startup is affected by the evaporator temperature, engine speed, and refrigerant pressure. Low evaporator temperature, engine speed at 0 rpm, and abnormal refrigerant pressure will all affect the normal operation of the compressor.

Performance parameters of AC compressor DZ1642840014:

Take the compressors of some models such as Shaanxi Auto DeLong X3000 as an example. Their voltage is usually 24V, the current is approximately 30A, the power can reach 80W, the driving method is independent, and the control method is generally manual adjustment.

Common Faults and Solutions of AC compressor DZ1642840014:

Compressor abnormal noise: This may be caused by loose adjustment screws of the air conditioning belt, belt wear, or problems with the electromagnetic clutch. You can tighten the screws, replace the belt, or inspect and replace the electromagnetic clutch.

Compressor not powered: Use a multimeter to check if the coil of the electromagnetic clutch is conducting, then check the power plugs of the high and low pressure cut-off switches, etc., to troubleshoot the wiring and power issues.

Compressor failure: If the compressor gets stuck inside, it may cause the belt to slip, smoke, and even break. In this case, the liquid storage dryer and the compressor need to be replaced. If there is a decrease or leakage of refrigerant and lubricating oil, check the O-rings of the inlet and exhaust pipes, and reconnect the pipelines to solve the leakage problem at the interface.

Fault code: For example, E001 indicates overvoltage or undervoltage of the host power supply, E007 indicates a fault of the outlet pressure sensor, E009 indicates a fault of the outlet temperature sensor, E025 indicates a FLASH reading error of the compressor controller, etc. Based on the meaning of the code, you can check the circuitry, replace the sensors or the controller, etc. to solve the problem.

The maintenance cycle for SHACMAN air conditioning compressors DZ1642840014 is not fixed and can be affected by factors such as the usage environment and frequency. Here are specific maintenance suggestions:

Lubricant replacement: It is strongly recommended to replace and clean the oil filter 2500 hours after the first operation. After that, if the system cleanliness is good, replace it once every 10,000 hours or annually. If the compressor is in a high-temperature operating state for a long time, check the chemical properties of the lubricating oil every 2 months. If they are， replace immediately.

Overall maintenance: A comprehensive inspection is usually conducted every 3 years. Mainly check whether the inlet and exhaust pressures are normal， whether all fasteners are loose， and whether there is any leakage.

Refrigerant addition: It is recommended to add refrigerant once a year. If the vehicle is used frequently， add it every six months. When adding， use professional equipment for precise operation.

Daily inspection： At the beginning of each season， a comprehensive inspection of the air conditioning compressor can be conducted. In harsh environmental conditions or after long-distance driving， it is also necessary to conduct appropriate inspections. During each vehicle maintenance， check the tension of the compressor belt to ensure it is in the appropriate state.
