What is a hydraulic testing machine?
In the fields of industrial production and scientific research, hydraulic testing machines are a common testing equipment, mainly used to test the sealing and pressure resistance of various types of containers, pipes, valves and other pressure-bearing components. With the recent increase in the Internet's attention to industrial safety and technological innovation, hydraulic testing machines have become one of the hot topics due to their key role in quality control. This article will introduce in detail the definition, working principle, application scenarios and recent hot topics of hydraulic testing machines.
1. Definition and working principle of hydraulic testing machine
A hydraulic testing machine is a device that tests the pressure-bearing capacity of a product by applying water pressure. Its working principle is to inject water into the object under test through a high-pressure water pump, gradually increase the pressure to the set value, and maintain it for a period of time to observe whether there is leakage or deformation. The following are examples of core parameters of a hydraulic testing machine:
| parameters | Typical range |
|---|---|
| pressure range | 0.1MPa~100MPa |
| Test accuracy | ±0.5%FS |
| Applicable media | water, oil or other liquids |
2. Application scenarios of hydraulic testing machine
Hydraulic testing machines are widely used in the following fields:
| Industry | Specific applications |
|---|---|
| Petrochemical industry | Pressure resistance test of pipelines and storage tanks |
| automobile manufacturing | Engine cooling system sealing test |
| Aerospace | Fuel tank pressure bearing capacity verification |
