Explosion-proof filter press"
Explosion-proof electric apparatus is adopted for the electric part, such as explosion-proof motor and explosion-proof pressure gauge with electric contact"
In terms of product design, if the filtering temperature is higher than 90℃, the customer should propose special requirements when placing an order, if the general filter plate is used as the high-temperature filter plate, its service life will be influenced; if the customer has requirements on explosion proofing, the special requirements on explosive-proof grade and using environment shall be specified.
This series of filter press can achieve such procedures as filter plate compressing, feeding, filtering, washing, pressing, liquid collecting and plate pulling, which features rational structure, simple operation and convenient maintenance.
Precautions for use
1. Confirm the startup of equipment will not injure any personnel or damage any articles before starting the machine.
2. Strictly prohibit from opening the electric cabinet, touching the terminal in electric cabinets, or opening the terminal box, otherwise electric shock and misoperation may occur.
3.Do not adjust the upper and lower limit indicators of pressure gauge with electric contact and the overflow valve at will after calibration. The pressing pressure shall be adjusted to a lower limit that no liquid leaks, and the upper limit shall be 1-2MPa higher than the lower limit. The pressure for plate pulling and discharging shall be 2-MPa.
4. Any damaged pressure gauge with electric contact and overflow valve of filter press shall be timely replaced, or the hydraulic pressure station and oil cylinder will be in a high pressure state for a long time, shortening the service life of hydraulic pressure station and oil life and resulting in pipeline fracture, even oil cylinder bursting.
5. Hydraulic oil cylinder and oil pipe may burst under a high pressure state for a long time; it is prohibited from standing right behind the oil cylinder after starting the filter press, or related personnel may be injured; "Emergency Stop" button shall be pressed in case of any abnormal conditions.
6. Feed pressure shall not exceed the normal filtering pressure of the equipment, or the filter plate will be damaged.
7. Anyone who is not trained on equipment and system maintenance is not allowed to open the electric cabinet for wiring; otherwise, it may cause malfunction due to wiring error.
8. Cut off the main power switch of filter press in process of equipment maintenance.
All parts of the whole filter press shall be seriously maintained in use, by which, the filter press can work normally. For this purpose, the following points shall be ensured:
(1) Keep proper records on the operating conditions and problems, and remove the faults of the equipment timely.
(2) Carry out insulation test and reliability test on the electronic control system, and repair or replace the elements not reliable in action.
