Description |
Shut circuit
Collection twenty
Measurement: twenty, 21, 22, 23, 24, twenty five, 26, 27
Nominal strain 210 bars, Highest stress 350 bars.
The CZPT MF axial piston variable displacement motors, Sequence twenty, are of swash plate design with variable stream ability ideal for hydrostatic transmissions with shut circuit. The movement rate is proportional to the motors driven velocity displacement, which, in flip, is established by the swash plate angle. The latter is infinitely adjustable among zero and maximum displacement. Circulation course is reserved by titling the swash plate to the reverse side of the neutral or zero displacement situation. These models and components are in shape, type and function replacements for CZPT-Sundstrand collection 20 factors.
– Suited for a selection of applications
– A number of displacements and options accessible
– eight different frame dimensions
– Engineered to give a prolonged services existence and reliability
– Set displacement motor can be operated in possibly route of rotation
– Several drive shaft possibilities and management possibilities
– Hefty responsibility bearings and shafts
– Simply serviceable
– Alternative areas also offered
– Immediate replacements for CZPT-Sundstrand
Features
The entire-length shaft with a substantial productive tapered roller bearing arrangement offers a high loading potential for exterior radial forces. Extra motors can be built on. The hydro-mechanical servo displacement management maintains the selected swash plate placement and consequently motor displacement.
Upon launch of the handle manage, the swash plate immediately returns to the null position and the circulation turn out to be zero.
Large circumstance pressures can be archived with no leakage even at the cheapest temperature by employing suited shaft seals. The servo valve arrangement offers the facility to integrate purpose regulators and distant management program. Axial piston models are made for simple servicing, comprehensive dismantling and reassembly can be carried out regular hand tools, and all elements or sub-assemblies are replaceable.
Servo Displacement Manage (CZPT response)
Standard by control take care of on the servo valve, the swash plate can be infinitely diverse in each course with the help of the servo system.
The motor displacement ensuing from any handle take care of place can be recognized using figures (5a – 5c).
The angle of the control manage for stroke initiation and for the ultimate placement of the stroke can range from device to device within the variety of the tolerance band.
