Products Introduction:

This product use float side panel, vane of dowel pin structure, technics of double-edged vane and wholly new low noise technology cure to process stator. Compared with other dosing vane pump, its advantages are:
♦ High working pressure – it can reduce the size of hydraulic actuator ,control valves and tubing, which makes for cutting the cost, you can also extend its working life by lowering the working pressure.
♦ High efficiency – both volumetric and mechanical efficiency are higher than 94%,so it helps to raise productivity, reduce heating and running cost.
♦ Smaller pressure fluctuation – it will reduce the noise of tubing and extend operating life of other hydraulic element.

♦ High fouling resistance –using vane of double lips structure provides high fouling resistance and long operation life
♦ Low noise – the vane structure of dowel pin which can decrease the force on the stator which comes from vane efficiently. We also adopt wholly new low noise technology stator, so it produces little noise. And the T*L series pumps with thicker body make for reducing mechanical amp litude and lower noise.
♦ Wide speed range – combining pump core which has large displacement with smaller pump body to produce large displacement pumps with low noise. In particular, this series of products is suitable for cutting machinery plastic machinery, leather machinery, pressing machinery, engineering machinery, metallurgical machinery and so on.

Application Specification:

Initial Startup Checks:
Check the accuracy of design and installation of hydraulic station:
♦ Make the distance between inlet and outlet as long as possible.
♦ The pipe orifice of inlet and outlet should be slope and the section eagle should be greater than or equal to 45°, in order to increase passage section ,slower velocity, recommend velocity in inlet is between 0.5m/s and 1.9m/s. and in outlet is below 6m/s.
♦ Confirm the oil ports are below the oil level in fuel tank in the worst-case scenario (example: all of hydraulic cylinder pistons are extending to the extreme position),
♦ Specifications of the air filter should be threes greater than the maximum return flow.
♦ Set the release valve for exhaust on oil returning pipe; and you can also slightly loosen the joint of pump outlet to vent until there are no bubbles in the oil spill, then you can tighten the joint to produce the same effect.
Notice: This method is suitable for low pressure and you should make sure the pressure will not rise.
Initial start:
♦ Check the accuracy of the location of oil ports.
♦ Pump should vent well when injecting oil.
♦ Inching running the pump for a few seconds, and you should loosen the relief valve on the outlet to reach the minimum pressure.
♦ Do not drive the pump in a high speed and pressure before the check is over.

Shaft&Coupling
Coupling&spline hole
♦ Coupling spline hole should be able to float and automatically, such as coupling halves are rigid coupling, the different axis is less than 0.15mm (TIR), in order to reduce wear and inclination angle of two spline axis deviation < ±0.05/25.4mm;
♦ Spline hole must be lubricated by molybdenum disulfide lithium-based grease or other similar grease.
♦ Coupling demand heat treatment to reach the hardness of 29~45HRC.
♦ The specification of spline hole should meet the one-level standards in SAE-J498b(1971) ,as the coordination is flat root and lateral teeth. 

Flat spline shaft
♦ T7, T67 and T6 series vane pumps provide a high strength key, hence you must use it when installing or changing the pump , or you can use a new key whose hardness is 27~34HRC and edge angle is 0.8~1×45° to avoid the circular angle in the key slot when it’ necessary to change keys. 

The load of shaft
♦ The construction of requirement of flat spline shaft is the same to the spline shaft’s. This series products is only allowed to bear transmission load, do not apply radial and axial load.
