Flow Dividers
Rotary gear flow dividers by Jihostroj a.s., that have been proven in operation, ensure efficient and reliable functioning when used in a wide range of agricultural, handling and construction machinery. These flow dividers enable using a single hydraulic source in multiple useful applications:
- Synchronous operation of multi-cylinder engines or hydraulic motors (linear and rotary).
- Proportional division of a pump output flow into several circuits.
- Pressure boost if pressure exceeding pump capacity is required (without transfer valves).
Jihostroj a.s. produces rotary gear flow dividers of five basic series. Three of them have a fixed axial clearance (unbalanced) and two of them have pressure axial balance.
Flow dividers of the smallest DPVM series, middle-sized DPV2 series and large-sized DPVT series feature with robust cast-iron design, absence of hydraulic balance, and fixed axial clearance. Input of pressure liquid into the divider is located in the middle body to which individual divider sections are connected from both sides. As standard, the DPVM and DPVT series are offered with 2 to 4 sections whereas DPV2 series may have 2 to 6 sections. At the same time, smaller geometric volumes of the DPVT series in the range from 10 to 16 cm3/rev can be made with up to 6 sections. Of course, it is also possible to supply dividers with an odd number of sections or with different geometric volumes according to a required proportion of the liquid flow distribution.
The bodies of the flow dividers of the DPVJ and DPVT3 series are made of high strength aluminium alloy combined with grey iron cast lids. Cogwheels of the divider, made of high strength hardened steel, are seated in floating bearing faces which provide axial pressure balance of the divider, thus ensuring high accuracy division. The DPVJ series is offered with 2 to 6 sections. The DPVT3 series is offered with 2 to 4 sections. A great advantage of such a divider type is an easy and smooth start-up along with a high accuracy of flow division even below 2%. Another advantage is good division accuracy even at low speed (small divided quantity).
