spx stone hydraulic pump troubleshooting(Solutions 2023)

Spx stone hydraulic pump troubleshooting is a big problem for the client. Believe me, because i have faced this problem so many times before. I’m sure you also know how difficult it is. For this reason, the spx stone hydraulic pump troubleshooting manual was created to help you diagnose and repair spx stone hydraulic pump troubleshooting quickly, easily and effectively. This hydraulic pump troubleshooting guidelines will first make a detailed introduction of spx stone hydraulic pump troubleshooting, then study the symptoms, causes (mainly three causes), and ways to solve it from different aspects.

⚠️⚠️⚠️WARNING:
*Repair work or troubleshooting must be performed by qualified personnel who are familiar with this equipment.
*Disconnect the power supply before removing the electrical cover. Electrical work should be performed by a qualified electrician.
*Check for system leaks by using a hand pump to apply pressure to the suspect area.Watch for leaking fluid and follow it back to its source. Never use your hand or other body parts to check for a possible leak.

spx stone hydraulic pump troubleshooting

We have prepared a very detailed spx stone hydraulic pump troubleshooting form for you, in which the problems and solutions correspond one by one, I believe that 90% of the problems can be solved as long as you check the form below.

Problem 1-spx stone Electric motor does not run

Cause	Solution
Unit is not plugged in.	Plug in unit.
No voltage supply.	Check line voltage
Broken lead wire or defective power cord plug.	Replace defective parts
Defective motor	Replace or repair motor

Problem 2-Spx Stone Hydraulic Pump is not delivering hydraulic fluid or delivers only enough hydraulic fluid to advance cylinder(s) partially or erratically

Cause	Solution
Hydraulic fluid level too low	Fill reservoir to 1-1/2″ below the cover plate, maximum.
Air in system	Bleed the system.
Debris is in pump or filter is plugged	Pump filter should be cleaned and, if necessary, pump should be dismantled and all parts inspected and cleaned.
Cold hydraulic fluid or hydraulic fluid is too heavy (hydraulic fluid is of a higher viscosity than necessary).	Change to lighter hydraulic fluid.
Relief valve or low pressure unloading valve out of adjustment	Readjust as needed.
Sheared drive shaft key(s)	Replace.
Motor rotating in wrong direction	Reverse rotation

Problem 3-Pump will not build full pressure

Cause	Solution
Faulty pressure gauge	Calibrate gauge
Check for external leakage	Seal any faulty pipe fittings with pipe sealant
Inspect the pump for internal leakage	Same procedure as above but for leaks around the entire inner mechanism. If there are no visible leaks the low-to-high pressure ball check may be leaking. Remove all parts. Inspect the check body for any damage to the seat areas. Clean and reseat if necessary. Inspect the ball for damages and replace if necessary, then reassemble.
Sheared key(s)	Replace
High pressure pump inlet or outlet ball checks in the pump are leaking	Reseat or replace valve head.

Problem 4-Automatic valve will not build full pressure

Cause	Solution
Unloading pressure is too low	Increase unloading pressure per chart, sheet 3 of 4
Defective or oversize seat on automatic valve	Replace ball and seat.

Problem 5-Electric motor cuts out

Cause	Solution
Extension cord is too long and/or not of sufficient gauge.	Replace
Faulty motor	Replace and repair
Overheated motor can trip circuit breaker in shop power panel	Allow motor to cool, reset circuit breaker located in shop power panel.

Problem 6-Foaming hydraulic fluid

Cause	Solution
Hydraulic fluid being splashed by counter weight.	Lower hydraulic fluid level to approximately 38 mm (1.5 inches) below the cover plate.

Problem 7-Cylinder(s) will not retract.

Cause	Solution
Check the system pressure; if the pressure is zero, the control valve is releasing pressure and the problem may be in the cylinder(s), mechanical linkage connected to cylinder(s), or quickdisconnect couplings.	Check the cylinders for broken return springs and check couplers to ensure that they are completely coupled. Occasionally couplers have to be replaced because one check does not stay open in the coupled position.
Inadequate air pressure (air motor only).	Increase air pressure.

Problem 8-Pump delivers excess hydraulic fluid pressure

Cause	Solution
Pressure gauge is not accurate	Calibrate gauge
Relief valve not properly set	Reset the relief valve.

Problem 9-Automatic valve will not release pressure

Cause	Solution
Sticking piston	Remove, clean and polish
High pressure hydraulic fluid is leaking past the low-to-high pressure check. This hydraulic fluid leaks back to the piston in the automatic valve, keeping the piston closed	Seat the ball check. Inspect and replace any faulty components.

spx power team hydraulic pump parts list

The SPX Power Team hydraulic pump is a great way to store and transport your compressed air. It has a capacity of up to 5 cubic feet, which allows you to store enough air for several jobs at once. The SPX Power Team also comes with a convenient pressure gauge so that you can monitor how much pressure is in the tank at any given time.

This 5 cubic foot air compressor features a quiet 5 horsepower motor that’s capable of producing up to 200 PSI. This means that it can fill up tires and inflate basketballs as well as other large items like mattresses and rafts. It also comes with an automatic shut-off feature if the pressure gets too high or low, which will prevent damage from occurring to your equipment or yourself.

spx stone hydraulic pump wiring diagram

The SPX stone hydraulic pump wiring diagram is shown in the figure below. The SPX stone hydraulic pump has a simple control circuit that is made up of two switches, two relays and a few other components. The following figure shows the basic schematic diagram of the control circuit used in the stone hydraulic pump:

The above-mentioned SPX stone hydraulic pump has an electrical motor, which is connected to a voltage supply through its terminals. This motor drives a gearbox which transfers power to a piston that is enclosed in a cylinder. When this piston rotates, it produces pressure at its opposite end that can be used to perform various tasks such as lifting or lowering heavy loads. The speed of rotation and the amount of pressure generated are both controlled by adjusting the voltage and current supplied to the motor terminals.
