How much pressure does a slide out pump need?
With You being familiar with hydraulic operation, the common operating pressure for the jack and slide systems is 3000 lbs. when working properly. The common current requirement is 20 amps. Have you checked the wiring for the pump and solenoids for loose or corroded connections?
What should I do if my hydraulic pump is not working?
The pump should be isolated as described for the fixed displacement pump. If pressure does not build up, the relief valve or pump compensator may be bad. Prior to checking either component, perform the necessary lockout procedures and verify that the pressure at the outlet port is zero psi.
Why are my slide out jacks not working?
Perhaps there is a screen that is clogged. With all the valves and solenoids and wiring it may be possible that one is not operating correctly or perhaps not at all. If there is hydraulic schematic available I could isolate the hydraulic flow of main pressure to the components.
What happens if the oil level is too low on a hydraulic pump?
As mentioned previously, if the oil level is too low, oil can enter the suction line and flow into the pump. Therefore, always check the oil level with all cylinders in the retracted position. If a new pump is installed and pressure will not build, the shaft may be rotating in the wrong direction.
How does a hydraulic slide on a pump work?
How the Hydraulic Slide Works When the rocker switch in the control panel is pressed and held to either extend or retract the slide(s), 12V DC power is applied to the motor in the hydraulic pump assembly.
When does a hydraulic slide start and stop?
The circuit breaker resets automatically after a few seconds. In general, the circuit breaker will trip if the number of amps consumed by the pump motor exceeds the rating of the breaker. As an example, a 50 amp, 12V circuit breaker is designed to support a nominal load of up to 600 watts. At 12V, 600 watts = 50 amps.
What causes a hydraulic pump to stop working?
The hydraulic pump stops if its circuit breaker trips, cutting power to the pump, even though you’re still holding the switch. The circuit breaker resets automatically after a few seconds. In general, the circuit breaker will trip if the number of amps consumed by the pump motor exceeds the rating of the breaker.
How many amps does a hydraulic slide take?
Barring problems as noted later in this document, most coaches will work with a 50 amp circuit. It’s not unusual for the hydraulic pump to momentarily draw more than 50 amps at peak, but the 50 amp circuit will still usually suffice.
