ASTM D217 Grease Worker for Measuring The Consistency of Lubricating Grease
Cone Penetration
Significance:
1. Cone penetration test results provide one measure of the consistency of Grease. With the help of the grease worker, the worked penetration results are determined. These worked penetration results are required to determine to which NLGI Consistency grade a grease belongs. Undisturbed penetration results provide means of evaluating the effect of storage conditions on grease consistency.
2. Penetration tests are performed on petroleum products to determine consistency and shear stability (lubricating greases) for design, quality control and identification purposes.
3. The Grease Worker is used to prepare for lubricating grease cone penetration, specified size, mass, and covers four procedures to measure the consistency of lubricating greases finish with a cone penetrometer.
1.Motor: Horizontal single phase capacitor-start motor. Voltage : 220V; power: 370W; speed: 1400 rpm. Connect via the coupling and turbine reducer.
2.Coupling: It adopts plum-shaped flexible coupling to connect the reducer and motor.
3.Turbine reducer: Double shaft reducer. Transmission ratio: 25:1, a pair of eccentric gear are mounted on the turbine shaft at both ends of the reducer.
4.Working unit: Installed on the engine base on both sides of the reducer, the motor is driven by the eccentric gear of the reducer through the coupling and continuously works with about 60 operations per minute.
5.Counter display: Small plate counter. When the time relay is selected, a number (time) is set arbitrarily with a ripple switch. When the digit reaches the set value, it can drive the relay to work and cut off the power of the motor.
6.Engineering stroke: 67~71mm, the diameter of each hole on the orifice is Φ6.35mm.
1. The spindle motor adopts a single-phase squirrel-cage motor, which runs smoothly; the reducer adopts a box-type gear structure, which works reliably; the counter adopts digital display, which is convenient for observation; the base is made of thick steel plate, which is firm and durable.
2.Plum-shaped elastic coupling is used to connect the reducer and the motor.
3. Double output shaft reducer. The transmission ratio is 25:1, and a pair of eccentric mechanisms are installed on the turbine shaft at both ends of the reducer
4. It is installed on the frame on both sides of the reducer, driven by the motor through the coupling through the eccentric mechanism of the reducer, and works continuously at about 60 movements per minute.
5.5-inch color LCD touch screen. When selecting the number of computer relays, use the wave switch to arbitrarily set a number (time), when the number reaches the set value, it can drive the relay to work and cut off the motor power.
6. This instrument is a double-acting reciprocating test equipment. It is composed of motor coupling, reducer, eccentric mechanism, working device and machine base, etc.
7. The computer monitors the motor temperature and torque parameters in real time, so as to protect the motor from damage.
8. It has the function of monitoring the ambient temperature. If it exceeds the test temperature range of 15-30°C, a prompt will be given.
