Delivery nozzles and hoses are critical components of a coolant system responsible for precisely directing and transporting coolant fluid from the reservoir or pump to specific target areas requiring temperature regulation. Nozzles control the flow pattern and spray characteristics, while hoses provide flexible, durable conduits for fluid transfer under pressure and across varying temperatures. These components are used in machinery and equipment manufacturing, where they facilitate efficient heat absorption or dissipation in processes such as metalworking, plastic molding, and heat exchange. The hoses are typically made from synthetic rubber (e.g., EPDM, Nitrile) or thermoplastics (e.g., PVC, Polyurethane), offering resistance to pressure, temperature, and chemical degradation. Nozzles may be constructed from stainless steel or brass, ensuring durability and precise flow control. Key parameters include nominal diameter (15–100 mm), operating pressure (1.0–1.6 MPa), burst pressure (4.0–6.4 MPa), operating temperature (-40–85 °C), flow rate (10–200 L/min), connection thread (G1/4–G1), hose length (0.5–5 m), hose inner diameter (6–50 mm), material (304–316 SS), and weight (0.2–5 kg). These values are reference ranges and must be verified for the specific model and application. Standards such as ISO 7241, ISO 7751, ISO 6803, ISO 5167, ISO 228-1, ISO 1307, and ASTM A312 are listed as procurement references; they do not imply certification or compliance. Always confirm model-specific values and standards with the legal manufacturer or supplier.
Coolant fluid is pumped through the system under pressure. Hoses transport the fluid from one point to another, maintaining flow integrity and resisting pressure, temperature, and chemical degradation. Nozzles, positioned at delivery points, shape and direct the fluid stream or spray onto target surfaces (e.g., machinery parts, molds, or heat exchangers) to facilitate efficient heat absorption or dissipation. The burst pressure (4.0–6.4 MPa) provides a safety factor over the operating pressure range (1.0–1.6 MPa). Flow rate depends on nozzle size and pressure, and temperature range (-40–85 °C) affects seal integrity. Proper selection of hose length, inner diameter, and connection thread ensures compatibility with the system.
