FLOW TEST PROCEDURES

The correct performance of this procedure will verify if the auxiliary circuit of the carrier is adequate to properly operate a Stanley attachment.

This procedure is generic in form. It is the end users responsibility to ensure that this procedure will work with his specific type of equipment.

If an adequate flow meter is not available contact your Stanley Hydraulic Distributor for assistance.

TEST PROCEDURE

1.With the auxiliary circuit (or kit) completely installed connect the flow meter between the tool inlet and outlet hoses.

NOTE:

Always use the hoses that are supplied for the at- tachment and make sure the machine hydraulic oil is between 90 to 120 °F. This will assure correct readings and adjustments.

2.With the machine setting at the mode that’s going to be used to operate the attachment record the GPM

_____.

Locate the correct flow for the attachment in the manual under the specification section. Adjust the machine to the correct GPM.

NOTE:

If possible, always set the machine to the highest GPM output mode. This will prevent the operator from over flowing the attachments.

3.Once the correct GPM flow is achieved fully open the restrictor on the flow meter.

4.With the machine in the attachment mode set in step 2 record the back-pressure. At this point the pressure reading on the pressure gauge is the back- pressure in the circuit. This pressure must not ex- ceed 200 psi/13.5 bar.

Excessive back-pressure will slow the attachments operation and lead to premature seal failures and over heating.

Record the back-pressure

 

psi.

5.Close the restrictor valve on the flow meter until the attachment relief starts to crack or open. The relief valve opens when the flow rate (GPM), indicated on the flow meter begins to decline rapidly. Locate the tools operating system relief pressure in the specifi- cation section in the manual. Adjust attachment re- lief to specification.

NOTE:

The relief valve pressure must be greater than the operating pressure of the attachment and three times the back-pressure. Never use the relief valve to control the flow rate in the circuit. Cracking pres- sure means the loss of 4 or more GPM.

Record the relief cracking pressure

 

psi.

Example:

 

 

Operation pressure of a breaker is 2700 psi. Back-pres- sure is 150 psi. A good rule to follow when setting the relief, multiply the back pressure by 3 then add this num- ber to the operation pressure of the attachment.

Operating Pressure

2700 psi

Back-pressure

450 psi

Operating pressure of the tool

3150 psi

The relief valve setting must be greater than the estimat- ed operating pressure of the tool. If the setting is lower, damage to the circuit may occur. Excess heat will be generated in the circuit which will damage the attach- ment and carrier.

HEAT LOAD TEST

With the installation kit properly installed and adjusted per the above procedure, conduct the heat load test as follows.

1.Connect the flow meter between the tool inlet and outlet hoses.

2.With the carrier set in the attachment mode, re- strict the flow meter until a pressure of 1000 psi is achieved. This pressure must be maintained throughout the heat test.

NOTE:

Closing of the restrictor may be required as the tem- perature increases.

Monitor the oil temperature from the flow meter until no change is noted. Record the time required for oil to stabilize. Record the surrounding temperature (ambi- ent temperature). Record the time required to stabilize

minutes.

Record the stabilized oil temperature

 

 

°F.

Record the ambient temperature

 

 

°F.

The “heat rise” is calculated as the stabilized tempera- ture minus the ambient temperature.
