Hydraproducts In-House Power Pack Testing

Our latest blog looks at our in-house Test Rig which is used to test many of our larger power units before they leave our premises for delivery to customers.

We are proud to be able to re-assure our customers that we fully test our units after they are built as to ensure our end users are satisfied with their product. This gives you, the customer, peace of mind that you have bought a reliable unit that, properly maintained, will last long into the future.

Below, we have covered the common test procedures for our Power units and how they are carried out:

 

Flushing

This is carried out to remove debris and contamination from all valve, pipework and reservoir internals. Always ensuring that sufficient flow is generated by our test rig ensures a high velocity turbulent flow (above Reynolds number 2000). This action will agitate any debris that is lodged in corners and crevices.

 

Flow

Guaranteeing we supply the correct flow rate is crucial to ensuring the customers application runs at the speeds expected. So Hydraproducts is able to measure the hydraulic pump flow rates using the latest digital flow meter technology up to 150lpm.

 

Pressure

Measuring pressures throughout a hydraulic system gives a hydraulic engineer a thorough knowledge of how it is performing and enables the setting of pumps and valves. Using a fully UKAS calibrated pressure test system, we are able to certify our systems with confidence that they will perform as expected.

 

Power

Measuring the power input to a system is fundamental to confirming that the system has firstly been designed correctly and secondly that the combination of the pressure and flow are being achieved within parameters set by our hydraulic design engineers.

 

Load Holding

Many of the systems we manufacture are for lifting or clamping applications, where load holding for long periods is critical to the machine performance.  Over the years Hydraproducts has developed a very stringent method of checking this that far surpasses those used by component suppliers. This enables us to check a whole system is holding pressures without decay.

 

Cleanliness

This test focuses on the cleanliness of the hydraulic system as any contaminants from particles and foreign bodies entering the system can greatly affect its operating ability, causing wear and even failure in vital system components. The test adheres to strict international cleanliness standards and is carried out on a regular basis.

 

Test Temperatures

A vital system test which focuses on the system temperature in varying operating conditions and is carried out to make sure that temperatures are within standard set tolerances and do not exceed them when increased load is added.

The test ensures that system components do not suffer damage and wear from the increased heat levels given off by the system, which could render a system inoperable and could potentially result in large repair bills.

 

Filtration and Particulate Cleaning

Hydraulic filters work to ensure that particulate matter doesn’t find its way into the hydraulic system.  It is essential that they are inspected and cleaned regularly to ensure excess particulate isn’t clogging the filter and affecting system performance.

Environmental conditions such as dusty workshops and foundries can affect the levels of contaminants entering the filter, and in these situations the filters will have to be checked more frequently and cleaned or replaced accordingly.
