  1. Composition and Overview of WLQ70/70 Jetting CZPT

WLQ80/100 jetting device is Company’s mature and stable solution, such as the system, engineering design and style of force management and protecting components, stock management of supporting components, merchandise production, product tests, packaging and shipping and delivery, submission and acceptance , technical services, shipping and delivery utilization and on-web site direction.
WLQ jetting equipment is composed of large strain pump, motor, coupling, tri-star starter manage box, reduction valves and security valves, etc. It is a required maintenance tools to carry out industrial cleansing on the rusty and dirty area of objects. This equipment adopts separated head of cylinder liner (nationwide patent, patent No. ZL 95 241067.2), and is characterised by high pressure, sufficient movement, smooth and trustworthy managing and flexible operation, as well as effortless upkeep, which is “a shining star” among related products.

  1. CZPT technique

CZPT technique of WLQ jetting device is shown in the diagram.
The entire program is made up of high pressure pump, reduction valve, safety valve, foot valve, h2o gun, enter-return flexible hose, drinking water tank and distribution box. In the course of functioning hours, fresh h2o injects into drinking water tank by means of flexible hose, and then enters the low stress chamber of pump fluid end via imbibing filter, imbibing versatile hose and imbibing stop valve. Substantial strain h2o is transported to workplaces soon after several segments of large strain hose. There are two varieties of operating situations:
Problem 1: It is controlled by the foot valve (drinking water gun is not employed). Such condition is usually used for the cleaning of pipe walls. Foot valve is utilized to handle the swap.
Problem two: It is controlled by water gun with switches (foot valve is not employed). Such condition is typically used for the cleansing of rusty and dirty surface area, as nicely as standard washing. Drinking water gun is utilized to control the change.
A reduction valve is deployed at the higher-strain outlet of the pump, to modify the real operating stress. Extreme drinking water shall return to h2o tank by way of the overflow port at relief valve and liquid return pipe. Pump protection valve is also deployed, which can be opened instantly when the pumping strain is enhanced thanks to unexpected factors, in buy to safeguard the pump and motor from shockproof force gauge and exhibit the working force.

three. Structural description
three.1 Jetting equipment
Jetting device is a gadget that can change drives of electrical motor or diesel motor to higher strain h2o fluid pressure energy. WLQ clear drinking water pump belongs to horizontal a few-plunger reciprocating higher-force pump.
Constructions of the pump you should see the diagram. It largely is made up of housing assembly, pump head assembly, coupling, base bracket, and electrical motor or diesel motor.
A few-section 4-pole AC motor or diesel motor can travel the rotation of three toss crank shaft through coupling and equipment reducer. It can also act on the connecting rod and slide block mechanism, make slide block reciprocates in the box slipway, plunger is also pushed to do reciprocating movement. When the plunger is retracted, vacuum is formed in hydraulic chamber. At this time, h2o self-cleaning tank enters the hydraulic chamber through fluid adaptable hose, dispensing tube and leading open suction valve. When the plunger is shifting forward, suction valve closes off. The drinking water is pressurized, the drain valve is opened, and currently being output outward by way of higher strain fluid collection block.
Tank components: Tank is the bearing human body of pump, which is manufactured of cast iron with large power. A single of its sides is established with gear box. A pair of gears inside of the box is created of higher good quality structural alloy metal, with hard-tooth-surface area of large precision following grinding and special heat treatment. It has the functions of clean rotation, lower sounds and outstanding wear resistance. The crankshaft is created of alloy metal, and crank surface area hardness with higher strength can be reached after specific heat treatment. Connecting rod huge end is lined with high tin aluminum bearing bush, with superb dress in resistance. Connecting rod massive stop moves in the crankcase.
Pump head assembly: Details of pump head assembly please see the diagram. 3 divided cylinder liners have replaced the conventional block pump heads and a few higher-pressure steel sleeves. These kinds of framework can essentially resolve the easily-damage connection in between major structural pump head and high strain metal jacket, which may possibly trigger pump head cracking if not repaired. 3 divided heads have tremendously simplified the upkeep disassembly, and diminished labor depth. Piston alloy area is dealt with with unique alloy, in get to boost the principal hardness, dress in resistance and corrosion resistance. Plunger and slider are related by pressure block, semi-toroidal, nut and locking screw. During the utilization method, adjustments in the axial gap and screw loose ought to be paid out interest to. Plunger is sealed with imported packing rectangular ring, with for a longer time seal lifestyle. None cross-hole assembly composition (see diagram) is utilized on the combination valve, which can realize flexible startup, reputable sealing, and resilient existence.
3.two Aid valve
Relief valve is an important factor of the hydraulic technique, whose function is to ensure the operation of doing work pipeline below preset stress. The total flow of the pump is routinely divided into two elements when passing by way of the aid valve, one particular is employed by h2o gun or a range of components the too much movement shall return to the tank, and sustain a continuous pressure.
Construction and operation basic principle:
Pilot operated compound-reduction valve is utilized. It composed of pilot valve and main valve.
Pilot valve element is connected with the back again liquid chamber of primary valve via the centre gap, also connects to P port in force chamber by way of two choke plug holes within the major valve aspect chamber. In this way, pipeline stress alterations of doing work pipeline can replicate to the pilot valve factor. When adjusting the pilot valve spring, strain between choke plug and pilot valve will enhance, resulting in stress in the working chamber. Alter the operating stress continually right up until suitable and stable functioning pressure is received. Beneath the circumstance there is no strain amongst choke plug and pilot valve, the operating pressure shall be zero.
three.three Basic safety valve
The position of safety valve is to carry out overload security on pump station, i.e. the pressure relief can be started routinely when the pump pressure is elevated thanks to unexpected factors.
Construction is demonstrated in the diagram. One particular conclude of the valve is connected with substantial stress chamber, when the strain exceeds a predetermined benefit, hydraulic drive shall battle from the spring drive to open up the valve and release stress. CZPTly, the force of safe valve shall be adjusted to one hundred ten% of the working strain. The nut is fastened after the adjustment to avoid loosening.
No make a difference think about from the risk-free operation of pump station, or from the safety issues of employees, the set up of risk-free valve must be taken into account.
