The eq-uipment is really a fire-fighting one advanced and rel i able in performance.(1)The diesel engine fire-fighting pump group can be formed as an automatic fire-fighting water-supply system (see Fig.1) together with an electric pump one, pressure sta biliz ing pump one etc. and the working process is introduced in "Diesel engine control system". The equipment can be jointly controlled with a fire-fighting center.The mode of water inlet of a fire-fighting pump can be self -pouring and suction-up and, upon the requirement in the fire-fighting standard, the former is generally used. It needs to spec-ially note in case of the need of the latter so as for this Co. to su-pply the automatic vacuum waterleading device, however, the dimensions of the pump group have to be changed somehow.X613512V135410241056102()()()()()o 5CAC220V The equipment takes X6135, 12V135, 4102, 4105, 6102 etc.series diese l engines as the power and these diesel engines (can be fitted with clutches) are combined wit h fire-fighting pumps through high elastic clutches to form the fire-fightingpump group , including diesel tank, radiation water tank, blower, bontrol screen (for the auto group) etc.parts.As the auto-control group, a separate diesel engine aut-ocontrol cabinet (programmable) carries out the system's au-tomatic starting, putting into use, auto-switching ( the motor pump group is switched to the diesel engine pump one or thediesel engine pump group to another group), auto-protection (warning and stopping protection for the diesel engine's over-speed, lower oil pressure, hogh water temperature, three times failures of starting, low voltage of accumulator etc.) etc.fun-ctions and also can be connected to fire-fighting centers of users or the autowarning device of fire to get a remote moni-toring.To ensure the group to normally working anenvironment o of below 5C, it can be fitted with and A C220V cooling-water preheater.XBCFields of applicationApplicable for the XBC series diesel engine fire-fighting pump control made in this Co., and also for the diesel enginefire-fighting pump and diesel generator controls of users.Fig.1Model and meaningpower of diesel engine shaftsemi-auto control fully-auto controlB diesel engine pump control D diesel generator controlcontrol feature of Liancheng diesel engine control cabinet1LEC-BZ(H)1. Control equipment of LEC-BZ(H) series diesel engine pu- mp group.System structure and principleFig.2() ()P1()P2()P1P2P2P1P1P2P1P3PwP3P4Pw Electric fire-fighting water-supply system is generally for-med with a pressure stabilizing pump, electric pump(main pu-mp) and automatic diesel enging pump(spare one) and its pri-nciple of work comes like this: usually the pipe-network's pr-essure keeps in between P1(low one)-P2(high one). The stabi-lizing pump starts once the pressure belows P1 and stops whe-n it rises to P2. It lowers slowly from P2 to P1 due to the leaka-ge of the network, thestabilizing pump starts again to keep it in betw een P1-P2. When the water quantity being used is grea-tly increased, the said pump can not keep the pressure at P1 and it quickly lowers to P3, the electric pump starts and the pressur-e rises to Pw(well) to meet with the demand for fire-fighting w-ater. In case of power-off or a failure with the electric pump, the pressure goes on lowering from P3 to P4, the diesel engine pump automatically starts to have it rise to Pw for water supply. The electric pump or diesel engine one has to be stopped thro-ugh artificial judgement and, if the leakage from the pipe-network is estimated much, it is necessary to increase pressure stabilizing tanks or make the pressure stabilizing pump norma-lly opened so as to avoid frequedt starting.Schematic drawing of auto-control system of diesel engine fire-fighting pump group(1) LEC-BH()110kW(2) LEC-BZ()()()110kW2LEC-DZ(H)230V/400V15s35min(1) LEC-BH series semi-auto fire-fighting diesel engine pu- mp's control equipmentThis electric control cabinet(box) has both manual and se-miauto control function and can display the oil pressure and water temperature of the diesel engine; the charging current of the accumulator; warn at too-low level of the oil tank; autom-atically start the diesel engine pump in case of a failure with the electric pump or power-off under the fire-alarm status and remotely start the diesel engine pump. This control mode is used for such an occasion as the power of the diesel engine is less than 110kW in general.(2) LEC-BZ series fully-auto fire-fighting diesel engine p-ump's control equipmentThis electric control cabinet(box) has both manual and fully-auto control function and can display the diesel engine's oil pr-essure and temperature and water temperature and the accumu-lator's charging current, watrn at an abnormal condition and w-hen the level of the oil tank is too low, as well as at an extra highspeed or low speed for stopping and when three startings are su-ccessively failed, automatically(also remotely) start or stop the diesel e ngine pump and charge the accumulator when its voltage becomes low and be connected to a fire-fighting center or an auto matic fire-alarm device to carry out the remotely linkage control.

Therefore, to guarantee normal operation of diesel engine, when selecting diesel engine, the matching of its power and the pump shall take the power loss under non-normal environmental condition of its operation into consideration so as to guarantee the reasonable matching of power of diesel engine and pump. Refer to K value in the following form.200kW200kW6 The oil tank used for the diesel engine of a power below 200kW can be directly mounted on the unit while the one for the diesel engine of a power over 200kW can be separated from the unit.

The height of the machine room shou ld be depend- ed on the equipment's height and the lifing apparatus, 3-5m as the effective height in general.2. The unit basis uses concrete structure in general and its round dimensions are the four peripheries of the unit feet plus 150- 200mm and depth is 400-600mm. The foot bolt stretches out of the bolt hole by a height about 2 times the diameter of the b- olt and a notc h is set in the middle of the basis and grooves are set round it for dirt oil and water discharge. The concrete fou- ndation must be solid and flat and, when to put the unit on it, place washers in between both unit bottom seat and bas is on both left and right sides of the foot bolt, the washers must be flat. Put a leveller on the pump shaft for correction to ensure the level of the driving shaft. After adjusting both bottom seat and pump, pour cement around the foot bolt, then after the ce- ment gets hardened, evenly tighten the foot bolt, then pour cement on the bottom seat to make sure of the unit stable and solid. finally correct the concentricity between the fire-fighting pump and the diesel engine's drving shafts, and the outer cir- cles of the two clutches must be linear and with an equal int- erval.o340C4305635m3. To ensure a good ventilation inside of the machine room, thetemperature th ere should not be over 40 and enough ventingholes must be set. When natureal ventilation is not sufficientfor the venting and radiating requirement, mount intake ve-ntilators on the venting holes to strengthen the ventilating p-roperty of the room.4. To ensure a fresh air inside of the machine room, it is necess-ary to prevent lots of heat from radiating inside and lowerthe noise. wrap the exhaust pipe of the diesel engine withasbestos, ex tend it outdoor and mount a rain-proof device onit or mount it 30downward and a silenser. The number ofthe elbow on it should be as less as possibe and the bent radiusof the elbow should be over 2.5 times the outer diameter ofthe exhause pipe, take it into consideration for the supportof the pipe to lower vib ration and prevent its weight from lo-ading on the diesel engine.5. When to mount both inlet and outlet pipes of the fire-fightingpump, do not let their weight loading on the pump so as to pr-event it against damage and its performance of running frombeing affected. The inlet pipe should be as short and straightas possible and, when it is as self-pouring, it must be mountedupward tiltedly towards the pump to make sure no air existsinside of the pipe. A filter screen and flexible connector sho-uld be mounted on the inlet and flexible connector, check valveand gate vlave on the outlet.6. It is not allowed to mount the control cabinet in the front of thediesel engine's radiator, otherwise the electric components in-side of the cabinet would be affected and not work normallyand it should be mounted on both sides of the unit or close toit so as to get a convenient operation. The wiring betw eenboth control cabin et and diesel engine should not be over 35m.(Fig. 6)123/o75Co35C31. Start: first make sure of the correct rorating direction of the fire fighting pump and the inlet valve is as N.O and outlet valve N.C. Before the pipe network starts with no water.A fter n o error is found, start the fire-fighting pump and, when the pump gets stable run, gradually open the outlet valve and adjust it to the work condition point for the pump to run. The outlet valve is N.O.when the network is filled with w- ater at usual.2. Run:when the pump gets a normal run, check the shaft seal and the bearing to see how it works. The leakage for the mecha- nical seal should not be over 3 draops/min and for th e stu- ffing seal should be dot drop. The bearing's temperature sh-o oould not be over 75C and its temperature rise not over 95C Stop running for a check ing case of an abnormal sound dur- ing the pump's run.3. To stop, first close the outlet valve, then the diesel engine.1151523451. According to the requirement in the fire-fighting standard, the unit must run once at least every 15-day with time not less than 15minutes so as make sure of it in a good status at any time. 2. Every time to start the fire-fighting opump, it should be done to check if the shaft seal is normal and if it needs to be adjusted or replaced.3. Periodically lubricate the bearing with grease.4. Completely drain the water inside of the pum p out in case ofa long time stop of the opump to prevent the pump casing etc. Parts from being frozen to result in split due to extra low amb- ient temperature.5. according to the provision for the maintenance of the diesel en- gine, daily maintenance should be kept for it by checking if the cooling water quantity, engine oil quaqntity, the accumulator's voltage, oil-pressure meter, th ermometer, speed-ometer and other control devices are normal.上海连成集团简介◇荣获“中国驰名商标”“国家免检产品”◇上海连成(集团)有限公司是一家著名的以研究制造泵、阀等流体输送设备、电气控制系统和环保设备的多元化经营的大型集团企业。
