What causes high boosted water temperature in KMT Streamline SL-V Plus?
High boosted water temperature can be caused by: * A blocked orifice. * A long deadhead condition. * Insufficient water supply. * Booster pump temperature switch malfunction.
What causes hot surfaces on the high pressure cylinder components of my KMT Streamline SL-V Plus Cutter?
Hot surfaces on the high-pressure cylinder components can be caused by: * A leaking discharge check valve, so inspect the condition of the seat, poppet valve, spring, poppet pin, and sealing head surface on the discharge end of the sealing heads. * A leaking inlet check valve, so inspect the condition of the poppet valve, poppet retainer, and the spring, if applicable, on the inlet end of the sealing heads. * A damaged sealing head, so check the cone flange surface of the sealing head for scratches or mechanical damage and replace if necessary. * A damaged high pressure cylinder, so check the high pressure cylinder for cracks.
What to do if the red light on the KMT Streamline SL-V Plus operator’s console is flashing?
If the red light on the operator’s console is flashing, it indicates that an alarm condition has occurred. Check the display panel for fault messages.
Why is there no hydraulic oil pressure in my KMT Cutter?
If there is no hydraulic oil pressure, it may be because: * The high and low limit compensators on the hydraulic pump are blocked with debris and are not controlling the swashplate. Disassemble the compensators, clean and inspect the components. * Incorrect motor rotation, so check the motor rotation.
What to do if the KMT Cutter pump shaft will not turn?
If the pump shaft will not turn, it could be due to: * The flexible coupling has failed, so replace the flexible coupling. * The hydraulic pump has seized, so replace the hydraulic pump.
What causes low cutting water pressure in KMT Cutter?
Low cutting water pressure can be caused by: * Low hydraulic pressure setting, so if operating in low pressure, switch to high pressure operation and check the hydraulic pressure setting. This is not applicable when the machine is equipped with the optional proportional pressure control. * Clean the high pressure adjustment valve. * Clean the compensators on the hydraulic pump. * Collapsed element in the high pressure line filter, so check the element in the high pressure line filter.
What causes abnormal fluctuations in high pressure water signal in KMT Streamline SL-V Plus Cutter?
Abnormal fluctuations in the high-pressure water signal can be caused by: * A large, worn, or damaged orifice, so make sure the orifice does not exceed the capacity of the pump and is in good working condition; verify that the jewel is installed in the orifice mount. * Check valve leakage, so inspect the discharge check valves in the sealing heads. * Seal leakage, so inspect the high pressure seal on the plunger. * Hydraulic control malfunction, so check the operation of the hydraulic relief valve.
Why is the hydraulic pressure present but there is no high pressure water pressure in my KMT Streamline SL-V Plus Cutter?
If you have hydraulic pressure but no high-pressure water pressure, it could be due to: * Proximity switch failure: From the Maintenance Screen on the control panel, jog the intensifier left and right and verify that the red light comes on at both proximity switches. * I/O relay failure: From the Maintenance Screen on the control panel, jog the intensifier left and right and verify that the green light comes on at both directional valve solenoids. * Coil failure on the directional control valve: Check the coils on the directional valve with a volt meter to verify if they are good or bad. * PLC failure: If there are inputs from the proximity switches, but no outputs, contact the KMT Customer Service Department for a logic review and verification of PLC failure.
How to troubleshoot low cutting water supply pressure on a KMT Streamline SL-V Plus Cutter?
To troubleshoot low cutting water supply pressure: * Check for a restricted water supply by verifying cutting water supply flow and pressure. * Inspect for a clogged water filter and replace the filter element if necessary. * Bleed any trapped air from the cutting water plumbing.
What causes high oil temperature resulting in shutdown in KMT Streamline SL-V Plus?
High oil temperature leading to a shutdown can be caused by: * Restricted cooling water flow, so check the cooling water source for proper temperature and flow rate. * A water modulating valve stuck open or closed, in which case you should replace the valve. * Scale build-up in the heat exchanger restricting the flow, so the heat exchanger will need to be flushed or replaced. * Air cooler temperature switch not operating properly, so replace the switch. * No power to cooler fan motor, so check the power supply to the fan motor.
