Advantages.
1. For the same power machine, the injection speed can be increased by more than 25%, which is more suitable for thin-wall precision injection requirements. Due to the ordinary PQ system power calculation to keep the pressure state as a standard, proportional variable pump system in this action when the power consumption is very low, so the oil pump displacement can be increased by more than 25%.
2. Reduced system heat, hydraulic components to extend the service life. Proportional variable system almost no throttling, overflow loss, system operation heat is greatly reduced. Not only can save the consumption of cooling water, low oil temperature so that the life of sealing components greatly improved.
3. Energy consumption is reduced and system efficiency is improved.
4. The control of numerical control proportional back pressure can be realized, and the plasticizing effect is improved.
5. Hydraulic system pollution level is reduced, the system failure is significantly reduced, the stability of the movement is greatly improved, the hydraulic oil use time than the conventional system to extend more than 3 years.
Proportional variable pump system has good self-adaptability, its output pressure and flow can be consistent with the load demand, to solve the throttle speed control system of the flow does not adapt to the pressure does not adapt to the problem, the energy loss is greatly reduced, the system efficiency is improved, energy saving effect is very obvious, compared with the ordinary quantitative pump + PQ proportional valve system, can save 25 ~ 45% of the power!
