Sumitomo QT series Internal Gear Pump Specifications:
Sumitomo QT series Internal Gear Pump is widely used in injection molding machines, forging machinery and elevators and other mechanical equipment.
QT Internal Gear Pump Features:
1. Low Noise Performance
The QT series internal gears are smooth and mute, and their excellent features are specially designed for gears. The sound is very low when used, and the sound is still smooth even at high speeds.
2. High Running Wear Resistance
In addition to the simple mechanical structure, the use of advanced hydraulic oil can reduce the mechanical surface and the wear and tear of the functional parts. QT chestnut can run at high pressure 320bar pressure, even if the use of general hydraulic oil, it is not easy to wear pieces.
3. Very Low Pressure Pulsation
QT pump can almost completely remove the pressure wave, it can be used as the system precision control of the ideal machine tool pressure
In order to protect the cooler from breaking, the explosion-proof valve or bypass unloading circuit must be installed when the cooler is installed in the oil return circuit. The best way to use: using another small auxiliary to extract the oil tank inside the mature oil supply cooler, so as to become an independent loop.
In order to ensure that the cooler does not break, when the cooler is installed in the oil return circuit, it is necessary to install an explosion-proof valve or bypass unloading circuit. Recommend the best way to use: use another small pump, extract the oil tank internal heat supply cooler, so as to become an independent loop.
When the pressure reaches the set value with the compensator, the flow reduces to the minimum automatically while the pump maintains the set pressure.
The pressure and flow are controlled manually.
當油泵的輸出壓力接近設定壓力時,則油泵的流量自動減少到最小流量,保持設定的壓力。
設定的壓力用手動調整。
These pumps are high pressure and high performance, which have been developed especially for low noise operation.
To comply with a variety of applications including injection moulding machines, PV2R series single pumps provide the output flow of such a wide range as from 5.8 to 237 cm3/rev (.354 to 14.46 cu.in./rev).
The intergral driving parts of the pumps are combined into a kit form and available for supply as a cartridge kit. Therefore, the replacement of the driving parts can be done easily.
Product introduction:
1. Installed in the pump oil suction side, prevent pumping oil into the dirt, protection system.
2. Prolong pump and system service life, reduce work continuously generated when the fault.
3. Specification complete, the flow range 40 l/min~800 l/min, filtration precision 100(standard products) can provide higher filtration precision.
