Parker accessories 381 series hose proportional valve from the United States

Working principle of Parker 381 series hoses

The Parker 381 series hose is a high-pressure hose widely used in hydraulic systems. Its working principle is mainly based on its structural design and material selection to ensure safe and reliable fluid transmission in high-pressure environments. The following is the working principle of this series of hoses:

Structural design:

Inner rubber layer: The inner rubber layer is made of synthetic rubber and is compatible with various hydraulic fluids, preventing chemical reactions and corrosion. This layer comes into direct contact with the fluid, ensuring smooth transmission of the fluid.

Reinforcement layer: The reinforcement layer is woven from two layers of steel wire, which provides high compressive strength, allowing the hose to work under high pressure without breaking.

Outer rubber layer: The outer rubber layer is also made of synthetic rubber, which can protect the hose from external environmental influences such as wear, cutting, and ultraviolet radiation.

working pressure:

The working pressure range of Parker 381 series hoses is 400-88 bar (5800-1300 PSI), which allows it to adapt to the needs of various hydraulic systems. High pressure capability is achieved through a double-layer steel wire weaving structure, which can evenly distribute pressure and prevent local excessive stress from causing rupture.

Temperature range:

The working temperature range of this series of hoses is -40 ° C to+100 ° C (-40 ° F to+212 ° F), which means it can work normally under temperature conditions without affecting performance due to temperature changes.

Fluid compatibility:

The Parker 381 series hoses have extensive fluid compatibility and can be compatible with a variety of hydraulic oils, water-based fluids, and other special fluids. This makes it highly applicable in various industrial applications.

Joint connection:

The connection method of hose joints is also an important part of its working principle. The Parker 381 series hoses can use various types of fittings, such as detachable, snap on, and Push Lok series. These joint designs ensure reliable connections between hoses and other components of the system, preventing leaks and accidental disconnections.

Application scope:

Due to its high performance and reliability, Parker 381 series hoses are widely used in various industrial fields such as manufacturing, mining, construction, and transportation. Its universal design enables it to meet the needs of customers.

In summary, the working principle of the Parker 381 series hose is mainly based on its double-layer steel wire weaving structure, synthetic rubber material, and various joint connection methods. These designs together ensure the reliable performance of the hose under high pressure, high temperature, and various fluid environments.

In terms of use and maintenance, the following points should be noted:

Choose the appropriate inner diameter: Ensure that the inner diameter is suitable and avoid increasing flow rate and pressure drop.

Consider medium compatibility: The inner and outer adhesive layers, pipe joints, and sealing rings need to be compatible with the medium.

Consider temperature: The medium temperature and ambient temperature should be within the technical characteristics range of the hose.

Determine the pressure range: working pressure, pulse pressure, peak pressure, etc. must comply with the hose specifications.

Choose the appropriate connector: Select the appropriate connector form according to the application scenario.

Consider application standards: Certain situations may require specific standard certifications or bending radius requirements.

The main uses of Parker accessories 381 series hoses and proportional valves in the United States are as follows:

381 series hoses: mainly used in the general market, industrial manufacturing, transportation, military equipment, engineering machinery, agricultural machinery, forestry equipment, machine tool processing, garbage recycling, material handling and other fields, especially suitable for petroleum based hydraulic oil and lubricant transmission scenarios.

Proportional valve: Parker proportional valves are mainly used for mass flow control and are normally closed, controlled by proportional solenoid valves. The fluid is driven by different valves, and the coil voltage controls the flow rate. For example, Parker plug-in valve models 001, 002, and 003 mass flow control valves are assembled with a valve body, valve sleeve, special zone coil, and internal valve to form an elastic seat and a hole.
