4, machine installation and commissioning

(A) the installation of the machine

1, lifting machine

Lifting unit when the first unload hydraulic station opened (if a larger unit can be all the boxes unloaded movable plate to reduce lifting weight, attention must not damage the surface of the plate, rack installed, the Plates according to the original order back). Hoisting rope used in hoisting should be hooked at both ends of the main beam lifting holes. Lifting must accurately identify the center of gravity, choose the right rope, wire rope access to parts and equipment need to use cloth or other soft material liner.

2, the installation of filter presses

Under normal circumstances, the level of filter presses to be installed on the concrete foundation structures shelf, thrust plate and legs with M20 × 300, or M16 × 300 of the anchor bolts fixed cylinder block is not fixed, to ensure the main beam in the force situations have a certain axial displacement. Should be based on the use of cement grout made the second, basic graphic needs smooth, easy to operate elevation in order to unload slag subject, taking into account the opening of plants into the water trench. Installation, rack should be level and diagonal correction. Processing of materials from the site install locations closer the better, when in order to facilitate the unloading operation, rack around the leave-one-meter space. The base machine should be higher than the basic face a certain size in order to take fluid device placed under the machine. Electrical control box should be installed with the corrosive gas separation operation room, to avoid damage to electrical components, affecting work.

Plates / box factory when the order should be based on the sequence of subject, are not free to reverse. Particular attention to the compaction plate side of the wall shall not be moved to other locations. Filter cloth can be special tools such as electric soldering iron hot material, filter cloth so as not to play flash.

Feed pump pressure and flow should be chosen to match with my company's products, and in return the feed tube on the road to install pipes and pressure gauges to ensure the pressure regulation needs. Such as the model is washable, washing pump feed pump with the option of requesting the same, but the wash water pressure should be slightly higher than the feed pressure. Best feed pumps were installed before the coarse filter to prevent debris into the garbage inside the pump and damage the machine parts. When feeding, slowly rotating the feed valve, so that the pressure gradually increased. Feed the total installation of the valve should be close to the thrust plate.

Hydraulic station to install the actual location of the venue can be determined according to the user, the installation should be avoided other slurry mixing tank, the impact of hydraulic components, the sensitivity of movement, and even damage to hydraulic components.

The installation of pipelines in accordance with nozzle piping layout diagram and user units in conjunction with the actual situation on-site installation, but it should be noted that the pipeline installation, use and maintenance must be convenient, pipelines can not take the wrong, the pipeline should be as short as possible.

In addition, the filter presses can be equipped with air compressors needed one, a gas tank for inflatable use. The above equipment and a variety of valves by the users themselves, may also be allocated on behalf of my company. Feed pump selection, can flow, particle size, viscosity and other requirements may be, but the pressure can not exceed the maximum filtration pressure filter press.

(B) of filter press debug

1, check the machine

(1) hydraulic station, electric control box, wipe clean, clean inside the fuel tank, check the power supply as well as compaction, on the return pipe is installed correctly, electric contact pressure gauge (DY) on the suitability of lower pressure settings, power supply wiring is safe and reasonable .

(2) rack, plate, rod clean it, check the plate is arranged neatly and correctly; check whether the folding cloth installation, if required to flatten

(3) Check the feeding, washing, blowing (as with a cleaning system) a liquid such as pipe, valves, the configuration is correct and reasonable.

2, electric control hydraulic debugging

(1) When the above items needed to check to confirm correct, to the fuel tank into a clean hydraulic oil to the provisions of the oil level (about 65L), connected to power, point move "return" button, observe the motor (D) is along the clockwise direction are transferred. Then, the anti-clockwise rotation pine high-pressure relief valve (YH), click "pressed" button, adjust the high-pressure relief valve (YH) to 2Mpa around, and then to move the piston repeated several times in order to row to make the air tanks.

(2) First, under pressure to choose a suitable feeding high-pressure relief valve (YH) locking pressure and electric contact pressure gauge (DY) the upper and lower limits. Regulation, the closed high-pressure relief valve (YH), anti-clockwise to open valve (YA), in the pressed state, a slow clockwise rotation safety valve (YA), so that electric contact pressure gauge (DY) pressure of 29Mpa , lock can be. Then click "return" button, Xie Wan pressure inside the cylinder, open the pressure relief valve (YH), in the pressed state, the slow clockwise rotating high-pressure relief valve (YH), so that the pressure up to 27Mpa lock; re - Click "Return" button, pressure relief, finally it is set electric contact pressure gauge (DY) of the pressure range 21-25Mpa (safety valves, pressure relief valve, electric contact pressure gauge before leaving the factory have been fine, generally did not require the user to adjust . For it is set to change the pressure of the above method can be adjusted.)

(3) re-enable the piston rod pressed board stimulate walking back and forth three times, and view up to electric contact pressure gauge oil pressure (DY) the upper limit will automatically shut down. In the packing state, the observed decline in oil pressure in the first on the pressure, the pressure drop rate of ≤ 3Mpa/10min as normal, when the pressure is reduced to electric contact pressure gauge (DY) lower limit, the motor (D) automatically start on the pressure, the second drop rate of ≤ 2Mpa/20min is normal.

3, filter part of the debugging

(1) compacting plate and holding pressure.

(2) open all fluid valves, closed washing, blowing (which can wash machine valves, feed about a quarter of the valve to open, start the feed pump, observe the filtrate and the feed pressure changes, such as pressure super - high, need to open the valve return pipe on the road to adjust. As the filter cloth of the capillary action, the beginning of filtration, the filtrate turbidity is a little bit normal. general, flow models to be filtered out after 5-10 minutes, the feed valve door opened and large, an undercurrent of 10-20 minutes.
