Sumitomo gear pump products in Japan is described
Name: Sumitomo gear pump
Model: QT single combined internal gear pump, QT double internal gear pump
Brand: Sumitomo Sumitomo
Origin: Japan
QT single coupling internal meshing gear pump
Characteristic：
1, ultra low noise performance of QT in internal gear pump gear contact smooth, quiet running. Its excellent characteristics for the special gear design, the use of its sound is very low, even in the high-speed operation, the audio is still smooth and flat.
2, high wear resistance in addition to the mechanical structure is simple, the use of advanced hydraulic oil, can reduce the mechanical surface and the functional parts of the wear. QT pump to 250bar pressure high-speed operation, even if the use of general hydraulic oil, it is not easy to wear parts.
3, very low pressure pulse QT pump can almost completely remove the pressure wave, it can be used as a system of accurate control of the ideal mechanical tool 4, the use of a wide range of pressure
Use matters needing attention:
1, hydraulic oil, please use the viscosity grade and ISOVG46 ~ 68 equivalent hydraulic oil. 70kg/cm - above the high-pressure recommended viscosity grade and ISOVG46 ~ 68 equivalent antiwear hydraulic oil. The use of flame resistant hydraulic oil (water glycol, phosphate, W/O emulsion etc.), please consult the company, the use of hydraulic oil must be clean, to prevent foreign matter or mixed with water, hydraulic oil color stratification, white bubble mixing, the working fluid has deteriorated, working fluid must be replaced.
2, viscosity temperature and viscosity for recommendation 20 ~ 500cSt (mm - /s), the working temperature is 0 C ~ 60 C. Please use the suction pressure in the -0.3kgf/cm - ~ +0.3kgf/cm - range (0.3kgf/cm - in the above, please use the high pressure oil seal). 　
3, oil filter oil suction side is set 150 m filter, oil filter on the side with 25 m filter, and the use of magnetic filter, etc., can improve the service life. 　
4, pump installation and installation of the pump base should have enough rigidity. The pump suction port on the side to absorb. The drive shaft of the pump is connected with the motor shaft with elastic coupling or chain coupling, eccentric error is 0.05mm, the pump drive shaft can not withstand any radial vertical force, lateral belt, chain and gear drive to prohibit the use of. Coupling in the pump drive shaft can be free assembly.
5, the distribution of oil pipe and pump port with all the tubing are connected by flange connection. According to the diameter of the suction side flow rate less than 1.5m/s, the negative pressure is less than -0.3kgf/cm - choice, and as short as possible. 　
6, start the pump before starting on the sliding surface of injecting lubricating oil inside the pump body, filled with oil. When the pump starts, the pump must be unloaded, and the pump body and the air in the oil suction pipe can be discharged. 　
6, the definition of the steering is always from the shaft end, the standard to the clockwise direction.
7, the maximum pressure of the definition of the maximum pressure used to account for a cycle of 1/3, continuous time control within 20 seconds.

Main characteristic parameter Specifications
[antiwear hydraulic oil viscosity 40cst (ISOVG32 oil, the oil temperature of 50 DEG C), speed 1500r/min, inlet pressure 0MPa]
Explain：
1 power refers to the maximum working pressure under the conditions of the required power.
2 when the working speed of N and 1500r/min, the driving power according to the approximate formula "table value x n/1500" to calculate the approximate value.
3 collocation to form a duplex pump.
