CZPT Mf collection  CZPT Piston Motor   for CZPT

CZPT CZPT-Sundstrand axial piston motor MF20, MF21, MF22, MF23, MF24, MF25, MF26, MF27

Description  

Shut circuit
Series twenty
Dimension: twenty, 21, 22, 23, 24, 25, 26, 27
Nominal strain 210 bars, Greatest stress 350 bars.
 
The CZPT MF axial piston variable displacement motors, Collection 20, are of swash plate construction with variable stream capacity ideal for hydrostatic transmissions with shut circuit. The circulation price is proportional to the motors pushed speed displacement, which, in change, is identified by the swash plate angle. The latter is infinitely adjustable among zero and highest displacement. Flow path is reserved by titling the swash plate to the reverse aspect of the neutral or zero displacement situation. These units and parts are fit, sort and purpose replacements for CZPT-Sundstrand sequence twenty factors.
 
– Suited for a variety of purposes
– Numerous displacements and alternatives accessible
– 8 diverse body measurements
– Engineered to provide a long support daily life and trustworthiness
– Mounted displacement motor can be operated in possibly direction of rotation
– A number of drive shaft possibilities and management choices
– Weighty obligation bearings and shafts
– Very easily serviceable
– Substitute elements also accessible
– Direct replacements for CZPT-Sundstrand
Features 
The full-duration shaft with a large effective tapered roller bearing arrangement gives a large loading capability for external radial forces. Added motors can be constructed on. The hydro-mechanical servo displacement handle maintains the selected swash plate situation and consequently motor displacement.
Upon launch of the manage deal with, the swash plate immediately returns to the null position and the stream grow to be zero.
Substantial circumstance pressures can be archived with no leakage even at the cheapest temperature by employing ideal shaft seals. The servo valve arrangement delivers the facility to integrate purpose regulators and distant handle technique. Axial piston units are made for easy servicing, full dismantling and reassembly can be carried out standard hand tools, and all components or sub-assemblies are replaceable.
Servo Displacement Manage (CZPT reaction)
Typical by management deal with on the servo valve, the swash plate can be infinitely different in equally direction with the support of the servo program.
The motor displacement resulting from any manage manage place can be proven using figures (5a – 5c).
The angle of the control manage for stroke initiation and for the final placement of the stroke can differ from unit to unit inside the assortment of the tolerance band.
