Description

Testing machines for rubber hoses, plastic pipes, and steel pipe Applications

This equipment is designed to test the pressure resistance and burst performance of various automotive hoses, rubber hoses, air conditioning lines, and assemblies; it measures parameters such as burst pressure and pressure-holding duration. It is suitable for use by quality inspection agencies, automotive component manufacturers, testing stations, and research institutions, supporting hose production, new product development, and performance research.

System Composition

一、Complete pressure testing system = Pressurization system + Control and display system

  1. Pressurization system: Centered on the Simingte liquid booster pump, responsible for system pressurization and maintaining stable pressure over extended periods;
  2. Control and display system: Manages drive air pressure, automatic pressure relief, real-time pressure display, and control of pressurization operations.

二、Control Methods and Functions

Utilizes PLC and touchscreen controls, featuring automatic pressure ramping, peak burst pressure locking, automatic shutdown upon specimen rupture, and automatic safety protection.

二、Applicable Test Standards

International Standard：

Hose installation and testing procedures are carried out in accordance with EN ISO 1402:1996 / NF T47-202:1996, “Rubber and plastics hose assemblies — Hydrostatic testing.

Domestic national standards：

Compliant with standards such as GB7939, GB/T5563 (general testing for hydraulic hose assemblies), GB383 (wire-braided rubber hoses), GB/T10544, and GB/T16897-2010, the equipment meets all testing requirements for hose burst, leakage, and pressure resistance tests.

三、Four Standard Test Procedures for Hose Bursting

  1. Constant-rate pressure increase → until specimen burst
  2. Constant-rate pressure increase → pressure hold → constant-rate pressure increase → until specimen burst
  3. Constant-rate pressure increase → pressure hold → pressure release (for pressure resistance/durability testing only; specimen does not burst)
  4. Constant-rate pressure increase → pressure hold → secondary pressure increase → secondary pressure hold → final pressure increase to burst (multi-stage stepped pressure to simulate operating conditions)

四、Equipment Features

  1. Equipped with a gas-driven automatic booster pump; output pressure is freely adjustable and precisely controllable.
  2. Features mature technology and a rational structural layout; the equipment is compact, lightweight, and boasts a neat, attractive appearance.
  3.  All pressure-bearing components utilize standard parts from internationally renowned brands; pressure-bearing sections feature a weld-free design for easy disassembly and assembly. The system offers a high safety factor and long service life, with simple, convenient maintenance.

六、Model Selection and Detailed Performance Specifications

1、产品型号Product Model

Product Name: Hydraulic Hose Burst Test Bench. Available Models: RGXT_7, RGXT_21, RGXT_40, RGXT_58, RGXT_70, RGXT_120, RGXT_160, RGXT_220, RGXT_300 (The number at the end of the model name indicates the equipment’s rated maximum test pressure in MPa).

2.Basic working principle

A high-pressure booster pump generates a high-pressure fluid medium, which is regulated by a pressure control system and conveyed via high-pressure piping into the test specimen; this enables the performance of long-term hydrostatic pressure resistance tests and ultimate burst tests on the piping.
