This kymograph is designed for recording mechanical activities of animal tissues in the physiological,pharmacological and biological experiments conducted by medical and pharmaceutical colleges or research institutes.It is with those characterictics:portable,solid,durable,runs noiselessly,steadily,reliably and reassuring. It can also shift rotational speed in a large range. The instument is simply assembled and convenient to servicing. It can be assembled with a passive drum for being used as a two –drum kymograph.

The kymograph includes two models , DJW-1 with timer and DJW-2 without timer.

 

 

 

1. Drum

The drum is made of aluminum alloy . The outside diameter is 170 mm and the height is 200mm . The record paper with a dimension of 534×200mm²  width , can be fixed at any height of the vertical shaft , which is 433 mm long and can be reeled off the worm wheel . The vertical shaft is connected with the worm wheel by taper joint , keeping the drum rotating smoothly and reliably . The radial saltation movement of drum is not beyond 0.5 mm.

2.Transmission mechanism

The Transmission mechanism consists of a low-speed synchronous motor , a speed gear train and a gear worm cluster . The gearshift is combined by racks and gears , which can be manipulated with a control knob for to abtain different rotational speed at 9 steps . The rotational speed and the chart speed of every step are as follows:

 

3. Timer

The 10-step tunable timer is composed of a transistor multi—delay circuit(Fig.1) supplied with a low-voltage power supply (6V) that can be used for electromagnetic recorder.

Time parameters of the following table:

 

 

 

 

 

4. Power supply     single-phase alternating current (220V ,50Hz).

5. Dimensions     240mm (D)×170mm (W) ×460 (H).

6. Weight         Approx.7kg.

 

 

 

 

 

1. Put the kymograph upon a horizontal expermental table.

2.Choose a rotational speed:Connect the power supply and set corresponding step and choose your needed rotational speed.

Note:Do not adjust speed when the motor shut down for avoiding elements damage.

3. Choose timer: Open the timer switch to [ON]. Then the timer lamp lights on . Set the timer knob to your needed step.

4. Disconnect the power source when finished.

 

1. After use , wipe the instrument clean and wrap it with a plastic cloth to prevent dust from getting into it .

2. Speed retarder, motor and mechanical bearing will be cleaned every year and oiled with instrument lubricant at regular intervals.
