DYNASET HYDRAULIC BENCH GRINDER IS A COMPACT UNIT , DESIGNED FOR BOTH MOBILE AND

WORKSHOP INSTALLATION. THE ONLY POWER SOURCE IS A HYDRAULIC SYSTEM TO PROVIDE GRINDER

WITH REQUIRED HYDRAULIC FLUID FLOW AT DEMANDED PRESSURE.

CONSTRUCTION

DYNASET hydraulic grinder is assembled on a robust steel frame and includes following components:

hydraulic motor

automatic rotation speed control valve

grinding wheel shaft with support flange and locking nut

adjustable grinding support

grinding wheels protective cover with an adjustable spark screen.

An automatic rotation speed control valve keeps unit's rotation speed constant when incoming hydraulic oil flow

can vary from nominal (= minimum demanded flow) up to value of 50% over the nominal.

CLASSIFICATION

DYNASET hydraulic bench grinder is designed and manufactured in conformity with the standard SFS 5349.

INSTALLATION

To enable putting DYNASET hydraulic bench grinder into operation only pressure- (P) and return (T) lines are

to be connected to the hydraulic system.

Ensure that the hydraulic fluid flow is sufficient to run the unit, i.e. at least the nominal flow must be available.

At the hydraulic flow less that demanded nominal rate the grinder runs at underspeed. If the hydraulic flow is so

excessive, that the automatic speed control valve is unable to handle it, the unit begins to hunt. In the latter case

the hydraulic flow is to be reduced either by replacing an existing hydraulic pump with a suitable one or using flow

limiter. DYNASET PRIORITY VALVE is recommended.

After having been connected to the hydraulic system, DYNASET hydraulic bench grinder is to be started by

directing the hydraulic flow to the units pressure port by means of control valve - manual or solenoid. Even simple

ball valve or three-way valve can be used.

To ensure DYNASETs proper operation, the hydraulic pressure must be set at least to the level, at which the

nominal power output is achieved (ref. to PARAMETERS). Lower pressure reduces output power. Maximum

hydraulic pressure is 210 bar (ref. to PARAMETERS). If the hydraulic system main pressure is higher, service

pressure relief valve must be used.

Ensure also that your machines hydraulic fluid cooling is working properly when DYNASET unit is in operation.

DYNASET HYDRAULIC GENERATORS ARE DESIGNED FOR EASY INTEGRATION INTO HYDRAULIC SYSTEM OF ANY

TYPE:

DYNASET hydraulic bench grinder works being integrated into an original hydraulic

system of a material handling machine.

Unit can be placed deliberately ensuring an easy access to the unit. Grinder should be

positioned on a horisontal surface. Additionally, return line must be connected to a

hydraulic oil tank in the shortest possible way in order to keep return oil pressure under

5 bar. It is possible to use DYNASET either as a plug-in grinder and connect hydraulic

power with quick couplings, or make a fixed installation on a carrier machine.

Ensure that the filtration capacity of a hydraulic system is sufficient.
