Description
Technical field
the utility model belongs to a kind of sea water desalinating plant.The sea water desaltination process that to be mainly used in reverse osmosis membrane (RO film) be strainer, can also be used for similar drink water purifying process.
Background technology
according to existing sea water desalinating plant, as the patented product " a kind of hydraulic energy-saving high-pressure pump " announced, the patent No.: ZL200520022289.3, this device has the function of energy recovery.See Fig. 1, by RO film 1, the compositions such as front end end cover 2, the pump housing 3, water shoot 4, recovery tube 5, fresh water pipe 6, excessive valve spring 7, surplus valve 8, rear end cap 9, piston pole socket 10, piston rod 11, piston bush 12, the left chamber of cylinder 13, piston 14, sealing-ring 15, the right chamber 16 of cylinder, outlet valve 17, rising pipe 18, water inlet pipe 19, two position three-way valve 20, water intaking valve 21.Its principle of work: exterior power source acts on piston rod 11, piston rod 11 draws piston 14 and does side-to-side movement, when piston 14 is from the low order end end motion left of cylinder body, vacuum is there is in cylinder in right chamber 16, under the atmospheric effect in the external world, the seawater outside the pump housing flows through water intaking valve 21 by water inlet pipe 19, finally makes seawater be filled in the right chamber 16 of cylinder, piston 14 moves to the high order end of cylinder body this moment, completes first time water absorption course; When piston 14 is from the end motion to the right of cylinder body high order end, cylinder produces high pressure sea water in right chamber 16, water intaking valve 21 is closed, outlet valve 17 is opened, water intaking valve 21 through closing shifts left end onto two position three-way valve 20, high pressure sea water flows into RO film 1 through outlet valve 17, rising pipe 18, low-press thick seawater and drinkable fresh water is produced in RO film, low-press thick seawater flows in the left chamber 13 of cylinder through recovery tube 5, the pressure of low-press thick seawater promotes piston 14 and moves to the right together with external force, discharged the energy of low pressure seawater, low-press thick seawater is external through water shoot 4 overboard pump.Repeat action noted earlier, continuous print sea water desaltination process can be carried out.
although this device has sea water desaltination and energy-conservation function, but also there is certain weak point, the central authorities of its piston 14 settle a sealing-ring 15, piston rod matches with piston bush, when toggle drives piston rod reciprocating, cause the swing of piston and cylinder body to produce to rub, add the resistance of motion of piston.Especially under being embodied in high-speed motion, working efficiency and the work-ing life of device is directly had influence on, the fault of device and scrap majority and be in this reason.It is also very serious that the friction of piston rod and piston bush simultaneously causes the damage of the two to lose efficacy.
Utility model content
the main technical problems to be solved in the utility model and object are: the deficiency existed according to existing sea water desalinating plant, improve on this basis, design one comparatively reasonably piston mechanism is mated, a kind of sea water desalinating plant with high efficiency energy saving pump is provided, fundamentally overcome because piston oscillation and cylinder body produce the phenomenon rubbed, reach and effectively increase work efficiency and work-ing life, reduce energy consumption, meet the demand of user.
main technical schemes of the present utility model: the sea water desalinating plant of band high efficiency energy saving pump comprises: front end end cover is connected with the pump housing by bolt with rear end cap, above the pump housing, chamber is built with two position three-way valve, at front end end cover built with water intaking valve, water inlet pipe, outlet valve and rising pipe, rising pipe is communicated with RO film, recovery tube connects RO film and the pump housing respectively, two position three-way valve is subject to the pressure-controlling in the left chamber of cylinder and the right chamber of cylinder and changes direction, surplus valve and excessive valve spring are housed above rear end cap and the pump housing, it is characterized in that: in the piston cylinder below the pump housing and the hole of rear end cap is built with a set of piston mechanism, a sealing-ring is installed respectively at the two ends of piston, in the middle of piston, a guide ring is installed, piston rod is through piston pole socket, be connected by nut with piston, piston rod cover has ceramic jacket, with metallic sheath, pin is fixing, respectively small sealing ring is housed at the guide body two ends of piston rod.
the utility model is through probationary certificate: 1, between ceramic jacket and small sealing ring, frictional coefficient is little, reduces the resistance of motion, significantly improves working efficiency, has dropped to energy consumption, and the wear resistance of ceramic jacket is better than metal and other material; 2, because there is the uniform contact of sealing-ring at piston two ends, reduce or eliminate the oscillating quantity of piston, piston is not directly contacted with piston rod guide body with cylinder body, piston rod, avoids abrasion, improve device work-ing life more than 3 times; 3, cylinder body with expensive high-abrasive material, and need not use engineering plastics manufacture, greatly reduces manufacturing cost.
