Engine system Intercooler air intake hose WG9730530011

Description

Introducing and Explaining the Function of the air intake hose WG9730530011:

The air intake hose WG9730530011 is a component in the intercooler system of heavy trucks engine parts. Its main function is to introduce air into the inter cooler, reducing the engine system temperature and enhancing engine performance, thereby avoiding engine failure caused by excessively high temperatures. The main Function:

1. Efficient Air Intake and Cooling: The middle coolant intake rubber tube is generally made of high-temperature-resistant silicone material or other high-temperature-resistant materials. It connects the outlet of the turbocharger with the inlet of the middle cooler, transporting the high-temperature pressurized air (approximately 150-200℃) to the middle cooler. After cooling, the temperature can be reduced to 60-80℃, increasing air density and optimizing combustion efficiency.
2. Protecting the Engine: It prevents engine detonation, pre-ignition, and other failures caused by high-temperature air, thereby prolonging the lifespan of core components such as cylinder heads and pistons.
3. Tolerating Complex Working Conditions: It can adapt to vibrations, bending deformations, and high-temperature environments in the engine compartment during heavy truck driving (with a short-term temperature resistance of up to 250℃).

The applicable models for the intercooler air intake hose WG9730530011:

1. All models of SINOTRUCKHOWO heavy trucks (such as TH7, T7H, N7W, etc.)
2. SITRAK series of SINOTRUCKtrucks (C7H, C5H)

Common Fault Analysis of the air Intake hose  WG9730530011 of the Intercooler:

Leakage or cracking of the air intake hose WG9730530011.

1. Due to high-temperature aging, the adhesive layer cracks (typical manifestation is the appearance of fine cracks on the surface): First, inflate to 0.3 MPa, immerse in water to observe bubbles (leakage volume > 50 ml/min requires replacement). It is recommended to also check if there is oil contamination inside the intercooler. If the turbocharger seal fails, it may lead to premature aging of the adhesive pipe.
2. Loosening of the clamp or deformation of the flange causing leakage at the interface. The torque of the stainless steel clamp is 15-18 N·m, and the torque of the flange bolts is 25-30 N·m. If there is loosening, it is necessary to tighten it with a torque wrench. Abnormal vibration or abnormal noise: Loose fixing brackets of the adhesive pipe or unreasonable layout. Observe the swing amplitude of the adhesive pipe at low speed (normal ≤ 10 mm), and listen for friction sounds with a stethoscope. If abnormal noise occurs, add rubber shock-absorbing pads (hardness Shore A 60 ± 5) and adjust the spacing of the brackets to 300-400 mm.

3. Excessive intake resistance: Mainly due to internal dust accumulation or rusted steel wire detachment (commonly seen in vehicles without regular cleaning of the air filter), measure the pressure difference between the turbine outlet and the intercooler inlet with a differential pressure gauge (normal ≤ 10 kPa, over 15 kPa requires cleaning). At the same time, every 20,000 kilometers of vehicle operation, use compressed air to blow from the adhesive pipe outlet in reverse (pressure ≤ 0.2 MPa) to prevent excessive dust accumulation.
