Towards three-cylinder plunger pump 1, form by pressure seal arrangement 2, computer automatic control system 3 three big parts by low for present embodiment; Hang down towards three-cylinder plunger pump 1 and form by shock absorber for output 11, discharge tube 12, suction pipe 13, suction air tank 14, fluid end 15, narrow V vee belt transmission system 16, power end 17, motor 18 and motor slide rails 19 etc.; The jig frequency of pump is 52 times/minute, and what plunger seal adopted is pressure seal arrangement 2, and this installs by suction sleeve 21, one-way valve 22, ball pivot sealing case 23, oil hydraulic pump 24, waste pipe 25 compositions such as grade; The important technological parameters of this pump and running state are monitored automatically and are regulated by computer automatic control system 3, when having an accident, can report to the police automatically, shut down, and total data and the time of output when shutting down.
Shock absorber for output 11 is two class pressurized container cylinders of gas-filled type, and an end that is contained in discharge tube 12 is equipped with safety valve, pressure gauge, pressure transducer and Decompression valves on it, and inlet is connected on the fluid end 15 by discharge tube 12, and outlet connects conveyance conduit.It is that accumulator mainly acts on is the irregularity of eliminating discharge capacity and pressure, improves the operating conditions of pump, eliminates the vibration of pump and delivery pipe, can prevent the direct damage of the water hammer of conveyance conduit to pump simultaneously.The inlet of suction pipe 13 taps into the slurry pipeline, and the other end is equipped with and sucks air tank 14, and three arms on it are received respectively under the suction chamber of three pump heads 6.Sucking air tank 14 is generic container cylinders, and pressure gauge and bleed valve are housed on it.Its effect is the discharge capacity needs that satisfy under plunger 7 friction speeds, improves the degree of filling of pump.Fluid end 15 is to be combined by three block casting steel pump heads 6, is fixed on the power end 17 with nut.Being equipped with in the pump chamber into and out of spring, self-acting valve, is the unique easily damaged parts of this pump, so its kind is minimum, have only four kinds on valve seat, valve body, valve spring and valve rubber, and working life is at 1500-3000 hour.The oil hydraulic pump 24 of pressure seal arrangement 2 is contained in the front end of pump head 6, communicates with pump chamber 4; Ball pivot sealing case 23 is contained in the plunger cavity 5 of pump head 6, and it is reciprocating that the plunger 7 of metal spraying inserts pump chamber 4 by ball pivot sealing case 23, cooperates the conversion process of finishing energy with pump valve 41.Power end 17 is the welding pump housing, and crank-linkage mechanism and true man that interior dress optical axis adds eccentric wheel type pacify gear pair etc., and rotatablely moving of motor 18 by narrow V vee belt transmission system 16, changes into the to-and-fro motion of plunger 7 through power end 17.
Referring to Fig. 5, pressure seal arrangement 2 is patented inventions, and the patent No. is (94243525.7) (including the ball pivot sealing case, the patent No. 91232369.8).It is made up of suction sleeve 21, one-way valve 22, ball pivot sealing case 23, oil hydraulic pump 24, waste pipe 25 etc.Suction sleeve 21 pipes connect the clear water source of 0.2-0.5MPa, and waste pipe 25 pipes connect uncovered pond.
Working principle is that example is described as follows with the single cylinder: in the induction stroke of main pump, under the pressure effect of clear water source 0.2-0.5MPa, the clear water one-way valve 22 of flowing through, ball pivot sealing case 23, enter the suction chamber 26 of oil hydraulic pump 24, promoting plunger 28 moves to main pump chamber 4, link up by weep hole 29 and discharge side 27, clear water enters the pond through waste pipe 25, in whole suction process, clear water flows, can wash cooling, lubricated plunger effectively, by the pressure reduction in 4 in Seal cage 5 and main pump chamber, plunger is implemented sealing.In the discharge stroke of main pump, under the pressure effect of oil hydraulic pump 24 in main pump chamber 4, finish its discharge process after because the effect of one-way valve 22, in suction chamber 26 and Seal cage 5, form a sealed volume, make the pressure in Seal cage 5 and the main pump chamber 4 form dynamic balancing.Because oil hydraulic pump 24 is suction boosters, make the pressure in the Seal cage 5, be higher than the pressure in the main pump chamber 4 all the time, and main pump chamber 4 internal pressures are high more, its pressure reduction is big more, and is just reliable more to the seal action of plunger.Therefore, this device has been broken by the conventional mechanism of self-energized seal part to plunger seal, leans on the pressure reduction in 4 in Seal cage 5 and main pump chamber, and plunger 7 is implemented sealing.Not only sealing is reliable, and long service life, can reach 5000-8000 hour.In the induction stroke of main pump, plunger 7 might be brought under the situation of slurry, and flowing of clear water can be washed effectively, cooling, tears traveller plug 7, but reduction paste bulk concentration not.Ball pivot sealing case 23 also is a patent, and it has relaxed the concentricity requirement of plunger 7 with Sealing, makes plunger 7 that the eccentric wear phenomenon take place never.
Ginseng Fig. 6, computer automatic control system 3, mainly by industrial control computer, various kinds of sensors, compositions such as transmitter A/D analog-digital converter, expansion I/O interface, printer and display device.Its major function is as follows: 1. the basic parameter of monitors pump: pressure, flow, jig frequency, temperature; Pressure in the pressure seal arrangement; The voltage of motor, the revolution of electric current, and guarantee the optimum Working of pump by the self-regulation motor revolution.2. calculate to show: the instantaneous assorted value of theoretical delivery, Coefficient of discharge, integrated flow, water-horse power, electronic output power and pump total efficiency.Basic parameter and calculated value storage 24 hours can access the total data of any arbitrarily therebetween at any time, and be printed as file.3. when having an accident, according to giving the alarm, do not handle autostop in 10 minutes to null value.As the value of going beyond the limit of, total data and time when shutting down by autostop warning and output.
In sum, YFB-6/100 type wiper seal three-cylinder plunger pump is a kind of advanced technology, reasonable in design, computer controlled automatic, can economical operation, and the new type ideal thick fluid pump with international most advanced level.Its easily damaged parts kind is few, long service life; The efficient height, energy saving; Volume is little, and is in light weight; Absolute static suction head is low; Operate steadily, noise is lower than 85 decibels.The sealing of pressure seal arrangement is reliable, and plunger, the concentration of not diluting slurry again can be washed, cool off, be lubricated to long service life effectively.
