WJQ5″6J-10剪切泵使用说明书
1.作用
WJQ5″6J-10剪切泵是一种专门用于剪切聚合物和粘土并已被现场使用和理论证实有效的机械。
在钻井液系统中,聚合物(或粘土)应提前充分地剪切以后,再进入钻井液系统,才能充分发挥其效用,改善钻井液性能,如果没有充分剪切,聚合物在第一次循环中就可能堵塞振动筛网,损失大量的聚合物,增加钻井成本,并且还可能使钻井液中的大尺寸的固相颗粒变硬而难以除掉;在完井液中,由于没有充分剪切,聚合物会产生许多“鱼眼”。
这些“鱼眼”会伤害地层,使地层渗透率降低,油气层减产。
经过事实证明WJQ56J-10剪切泵具有优良的性能,它能为高分子聚合物(也能为粘土)迅速水合提供高度的剪切,解决聚合物(或粘土)在钻井液中或完井液中因水合不好而存在的突出问题。
同时,使用WJQ56J-10剪切泵能使聚合物用量减少15%以上,膨润土
用量减少30%以上,并且改善了泥饼和液流损失,降低钻井液剪切比速率,提高凝胶强度,达到了国外同类产品的先进水平,其轴封结构更可靠,使用维护更方便。
2.原理
WJQ5″6JC-10剪切泵密封采用了非常可靠的机械密封,保证无泄漏。
泵内部配有一个300mm不锈钢涡轮(其上有导叶、叶轮、44个喷嘴、4个收集室),及一个剪切板,能够产生超过s的小端剪切(液体剪切),当液流通过剪切泵时,有一半(50%)的液体在涡轮收集室的强力推进下将被剪切两次。
该涡轮剪切泵安装在一专用底座上,并用皮带轮、窄V 带和55KW/75kw防爆电动机驱动,与剪切泵配套使用的还有一个尺寸适合的ZHP150混合漏斗,这样组成了一个完善的剪切及水合作用系统。
由于该泵轴封的改进,使其寿命大大提高。
如遵循该泵安装及特殊条件应用的规则,将进一步提高其性能。
本公司将对在油田及工业应用中有利于提高该泵性能的一般及特殊建议进行处理。
注意:该泵不能用于活性泥浆系统,因为系统中的钻井固体及重晶石,它们在受到剪切时将很快损坏该泵。
原理如图一:
图一WJQ5″6JC-10剪切泵原理图
聚合物流体从V流道进入,并以平行与剪切板P的方向抽送,收集室内液流量的50%通过44个喷嘴N射出,并以高速冲击剪切板P,然后在M处90方向进入泵的蜗壳收集室。
总流V及射流N沿着剪切板流动到达剪切盘的尖端T,在尖端有许多牙齿,高速旋转的牙齿使聚合物(或粘土)再一次被剪切。
这样就完成了聚合物(或粘土)高度剪切而迅速水合。

1.Introduction
The WJQ5″6J-10shear pump generation is uniquely designed pump for shearing polymers and clays.
To improve the drill fluid properties, the polymers or clays should be highly sheared before adding them to the drill fluid system. If not sheared, the polymers maybe jam the strainer and will result in losing amount of polymer and increasing drilling costs, and the large-size solids in the drill fluid will harden and difficult to clear away as well. The WJQ5″6J-10shear pump has proven best for applying the high shear necessary to hydrate polymers and clays and to their best properties. Using the WJQ5″6J-10shear pump reduces the bentonite clay needed by 33% or more and polymer needed by 15% or more. It also improve fluid loss and filter cake, builds gel strength, and low shear rate viscosity to better hold up solids. With reliable shaft seal structure and more convenient in operation and maintenance, it comes up to advanced world standards in the same products.
2.Principle of operation
The WJQ5″6J-10shear pump adopts a set of mechanical seal for no leakage at stuffing box. Inside pump is a 300 series stainless steel turbine containing 44 nozzles, four scoops and shear plate. Fifty percent of the fluid is sheared twice each time through the pump. This turbine shear pump is mounted on a special base with belts
and sheaves to drive pump, OSHA type belt guard and a 75HP/102(55kw/75kw) 1480 RPM EXPLOSION PROOF U/L approved electric motor, 460 volts, 3 phase 60 cycle. Included is a special hopper(ZHP150) with nozzle sized for this application and one mud kit as a package in order to build a complete shear and hydration system. The pump is designed to give longer service life through the improved shaft seal.
There are many principles of proper pump installation and application as well as special considerations for the pump design which, if followed, will further enhance the performance of your WJQ5″6J-10 turbine shear pump.
This document will deal with both general and specific recommendations for improved WJQ5″6J-10turbine shear pump performance in both oilfield and industrial applications.
Warning! This pump can not be used on active mud system since it will shear drill solids and barite. These solids will also damage pump very quickly.
The principle sees figure 1.
Figure 1 Principle diagram of WJQ5″6J-10 shear pump
Fluid enters at “V” and is pumped parallel to the shear “P”. The chambers scoops 50% of the volume being pumped and jets that fluid through 44 nozzles “N” and impacts the shear plate “P” at very high velocity at “M” 90 degrees to the fluid entering the pump. The total fluid “V” and “N” travels down the shear plate to “T” where the fluid is further sheared due to the shape and speed of the plate tip.

6.Guide to installation, operation and maintenance of the WJQ5″×6"JC-10" shear pump.
Foreword
The general problems to installation, operation and maintenance of the WJQ5″×6"J-10" shear pump are introduced in the guide(for your information only), please contact our company for insolvable problems in this guide and will be replied in time.
Emphases
Operate the pump only in the performance range and service for which it was designed.
This pump employs mechanial seal as its primary seal and packing seal as its secondary seal. Packing seal can be compacted only when mechanical seal is disabled. Otherwise, the seal may be damaged.
No-load running time of the pump cannot exceed 5s. The pump must run under the condition of being filled with liquid slurry. Otherwise, the mechanical seal may be damaged.
Installation

(Table 4)
Pump installation
The pump should be located near the liquid source so that the suction line can be short and reduce losses. The
foundation should be sufficiently rigid and substantial to absorb any vibration and support the base plate at all points. The base plate should be installed in a level position.
Pulley installation
A. The axes of two pulleys must be parallel to each other
and the end surface error can not exceed 2mm.
B. The belts should be aligned and tightened.
C. The electric motor must be mounted stably.
Connection of suction pipes
A. The suction line should be equal to or larger than the pump suction.
B. The capacity of a centrifugal pump should never be adjusted by throttling the suction line, but a positive shut-off valve of a type to cause minimal turbulence should be installed in the suction line to permit the closing of the line for removal of the pump for inspection and
maintenance.
C. The suction line should be designed to eliminate any air pockets. The pipes should gradually slope downwards to the supply source to eliminate air pockets. Please use a vacuum pump or foot valve for priming if you operate the pump the pump under the condition of suction lift.
D.The suction line should have a straight section into the pump of a length equivalent to at least two times its diameter.
E.For temporary hook-up when flexible hose is used, a non-collapsing hose is essential since the suction line pressure is often below atmospheric pressure. A collapsed suction line will result in below average or complete loss of flow.
Discharge pipes
A.A positive shut-off valve should be located in the discharge pipe to permit the closing the line for removal of the pump for inspection and maintenance.
B.All pipes(including suction pipes) should be independently supported and accurately aligned. The pump must not support the weight of pipe or compensate for misalignment.
C.If operating conditions are not known with sufficient accuracy, it will be necessary to provide a throttle valve in the discharge line to ensure that the pump operates at the design point.
D.If the pump is connected to a pressurized system, it is important to install a check valve between the discharge and the throttling valve. The check valve will prevent back flow through the pump. Back flow may cause the impeller to become loose on the shaft. A loose impeller will likely lead to mechanic damaged and fluid leakage beneath the shaft sleeve.
Operation
Preparation
A.Pump rotates freely by hand.
B.Check the pump rotate direction, the correct direction can be found by an arrow on the casing.
C.Open the suction valve fully.
D.Pump and suction line full of fluid for venting air.
Operation for running
Start the motor after finishing all the preparations.
Lubrication
C.B earings lubrication
c.A dd a good grade of 10w30 weight motor oil until the middle level of dipstick. Do not overfill the
oil. High levels nay cause churning and
overheating of the bearings. Oil should be changed
every 90 days or 1000 hours.
d.U nder the special condition, you may select a grease which can dissolve with the motor oil for
lubrication.
D.S tuffing box lubrication
c.T he stuffing box may be re-lubricated with grease as often as necessary to prevent the packing form
overheating. It should be lubricated at least once
a day.
d.O n filling, grease should be pumped into the box while turning the shaft until it comes out around
the packing gland.
Maintenance(Reference to figure 3 and table 2)B.D isassembly:
n.R emove the pulley kit.
o.R emove the Pressing board(29).
p.R emove the pump case(1).
q.R emove impeller(2),shear plate(3)and Strengthening board(4):Screw the left-hanged nuts
(36&37) off use a wrench(Restrain the shaft at
the pulley end to prevent rotation, If you do not have a wrench). Put a block of wood against the ribs of turbine and hit the wooden block with a hammer to withdraw the impeller(2).
r.R emove reinforce sleeve(35) and mechanical seal (34).
s.W ithdraw protecting board(5) and stuffing box (6).
t.R emove the shaft sleeve(33). A wedge may be driven between the end of the sleeve and the shoulder of the shaft to free the sleeve.
u.R emove the blocking mud ring(24).
v.R emove left right cover(7&19).
w.P ull the complete shaft and bearing subassembly from the frame.
x.R emove the lock nut(17) and the lock-washer(18).
y.R emove the bearing frame and bearings(14) from the shaft. Note:Impacting of the entire shaft
assembly against a board on the ground will remove
the bearing assembly.
z.T he bearing(9) may now be pressed off the shaft.
Note: A piece of 3 standard wall pipe slipped
over the shaft and impacted against the inner race
of the bearing works exceptionally well. B.Inspection
g.Impeller:Replace if the impeller shows excessive erosion, corrosion, extreme wear, or vane
breakage.
h.Shaft: Check for run-out to see that the shaft has not been bent. If run-out exceeds , replace the
shaft. Bearing seats and oil seal area must be
smooth and free of scratches or grooves. Shaft
threads must be in good condition. Replace shaft,
if necessary.
i.Shaft sleeve: Sleeve surface in the stuffing box
must be smooth and free of grooves. If grooved,
replace it.
j.Oil seal: The removed oil seal must be replaced.
k.Ball bearings: Replace if worn, loose, or rough and noisy when rotated. New bearings should not be
unwrapped until ready for use replacement bearings
must be of the proper size and type as supplied with
the original equipment.
l.Seal O-ring: It is recommended that all O-ring and gasket seals should be removed during disassembly
and replaced. In those cases ones can be reused if
they are not worn or otherwise damaged. C.Assembly (reference to figure 3 and table 2)
g.A ll parts should be clean before assembly. This is especially important for O-ring grooves, threads,
gasket surfaces, bearings and bearings surfaces.
Any burrs should be removed with crocus cloth.
h.F irstly slip the bearings (14) onto the shaft. The
two bearings are to be mounted back-to-back (that is, the sides of the bearings with the manufacturer’s name and the bearing number are placed together), with lock-washer in place tighten locknut with the bevel positioned against the bearings tighten the locknut to 346M/1N of torque. Then, put the shaft with bearings(14) into the frame from left and slip the bearing(14) onto the shaft from right of frame.
i.T he sleeved area of the shaft must be lightly coated with anti-seized compound before installing the sleeve(33).
j.I nstall the impeller. The clearance between the back of impeller and protecting plate is 。
k.W ith the packing gland in position, swing the gland bolts into place. Initially tighten the gland hard to compress the packing. Then back off the gland bolts and retighten only finger tight. Caution: Tighten the gland against the packing finger tight only If packing is over-tightened it may be burned when the pump is started.
l.A ssembly can be proceeded as the opposite sequence of disassembly. The pump rotates frees by hand
after assembly. If not free, adjust the shaft
assembly by loosening or tightening the
bolt(26)/nut(27).
Note:In spite of adjust the shaft to left or right, the bolt(26)/nut(27) must be tighten to prevent the shaft move after adjusting complete.
E.Failures and shooting
f.T he packing seal leaks seriously, the packing and shaft sleeve surface have been seriously worn.
——Remove the packing. Bend a wire with 90 degrees and pull it down the sleeve surface and renew the
shaft sleeve if grooved. If packing is
over-tightened it may be excessively worn.
g.T he polyurethane lip seal’s(20) excessive erosion may result in excessive leakage.
——Replace it.。
