cylinder inlet port to supply pressure oil pump liquid type oil absorption since. Strong pressure from the sucking pump ability, without external oil supply. If found to
reduce cylinder speed or stuffy that should be made, when the car hydraulic pump repair, check the impeller marginal whether existing injury blow is like, the internal gear pump space is
not too large. About suction fluid from the inner, cylindrical plunger pressure oil tank shall not be less than the lower limit of the oil standard sufficient enough to maintain insurance,
the number of hydraulic oil. Cleanliness of the hydraulic oil pump pressure fluid, high life expectancy longer apply.
????2, hydraulic piston bearing the heaviest axis is to support member unit, assuming the bearing clearance occurs, you can not pump fluid within the Department of friction
normal space permits three pairs, also deputy rub together all bad break The hydrostatic bearing oil film thickness, reduce the number of bearing shaft pump plunger used to make a life.
According to data supplied by the pump manufacturer are flat bearing axis, using life expectancy is 10000h, but also to go beyond this need to change the value of the new port. To the axis
of the discharge under split bearings, no professional inspection equipment is unable to check the bearing axis gap swim out, can only use visual, such as found in the table change or
roller marks marked with pale, it must be replaced. In more should, when bearing axis change note bearing the letters and the type of the original column are large selection of plunger
shaft bearing large load bearing capacity, the best gauge of the original acquisition of 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.
