Our website: www.pepfluid.com http://www.pepfluid.com/t6c-vane-pumps-and-cartridge-kits/ the former grid, home plant products, assuming that the replacement of another brand, Please bearing axis due to the experience of teaching staff look-up table on the exchange, the intent is to uphold the like of fine grade and load capacity of the bearing axis.Fixed displacement due to construction constraints, usually only for that gear pumps use the constant flow of hydraulic source. However, the attachment into the threaded connection on the progress of its planned combination valve function, decrease system cost and system reliability of progress is useful, therefore, the gear pump function can come near the price of expensive, messy piston.????For example, directly on the pump control valve device, eliminating the need for tubing between the pump and the direction and control of the capital. Fewer fittings and connections can reduce the leak, then the progress of the operation reliability. And the pump itself means a valve can be reduced circulating pressure circuit, the progress of their job function. Here are some of the gear pump can improve the basic functions of the circuit, some of which proved feasible fundamental loop, while others belong to innovative research.????Unload circuit????Uninstall element will combine the high flow pump and low-power single pump. Liquid discharged from the outlet of the two pumps, pressure and play to reach the book (or) traffic. In this case, the flow from the pump outlet flow loop to put imports and reduce the pump output flow system, ie magnetic power cuts to some desired value slightly higher than the high-pressure job. Percentage drop in traffic depends on the moment not uninstall total displacement displacement ratio, or a combination of a screw connection unloader valve to cut or even eliminate the piping, channels and accessories and other possible leak.????The most simple element is operated by manual unloading. Stretched spring so that the unloading valve is turned on or closed, when an operation signal to the valve, the valve off a good situation to be switched. Lever or other mechanical tissue is the easiest way to operate this valve.????Guidance and control (pneumatic or hydraulic) unloader valve is an improved method of operation, since this is the valve can be controlled over long distances. The biggest development is the choice of electrical or electronic closed solenoid valve control, which not only can be used long-distance control, and can be manipulated computer initiative, often think of this simple uninstall skills is the best situation to use.????Manual unloading element commonly used in the operation and the need for the rapid flow and fast operation of large and require high flow and to reduce the flow of accurate manipulation circuit, such as fast flexible boom circuit. When you uninstall the circuit of Figure 1 without an operation signal effect (left position), the output of the circuit has large traffic. About a normally open valve, the output circuit under normal little traffic. Pressure sensing unloading is the most throughout the program. , The stretched spring effect so that the unloading valve is in its high flow orientation (left position) shown in Figure 2. When circuit pressure relief valve reaches the preset value, the relief valve opens, unloading valve in the hydraulic pressure and under the effect of switching to its small flow orientation (right position). Pressure sensing unloader valve is essentially a system pressure that is unloading reach active unloading element throughout the process instrument for measuring fragmentation and hydraulic vise.????Unload circuit flow sensor in the unloading valve is pressed by a stretched spring will flow to large azimuth (left them). The valve is fixed aperture scale by saving equipment required flow rate to determine the best engine. If the engine speed exceeds this the best plan, then save the hole will increase the pressure drop, and then shifted to the small flow unloader valve orientation (right position). Thus high flow pump adjacent elements can be made on the maximum flow rate savings scale, therefore less energy consumption loop, smooth operation and low cost. A typical use of this circuit is that the circuit flow constraints of the best planning in order to improve the function of the entire system, or constraints machine during high speed circuit pressure. Commonly used in waste carrying trucks.
