  1. Composition and Overview of WLQ42/250Jetting CZPT

WLQ80/one hundred jetting device is Company’s mature and stable solution, including the method, technological innovation design and style of force control and protecting factors, inventory management of supporting elements, solution manufacturing, solution tests, packaging and transport, submission and acceptance , technological services, supply use and on-website advice.
WLQ jetting device is composed of high force pump, motor, coupling, tri-star starter handle box, aid valves and basic safety valves, and so forth. It is a needed servicing products to conduct industrial cleaning on the rusty and filthy surface area of objects. This equipment adopts separated head of cylinder liner (national patent, patent No. ZL 95 241067.two), and is characterised by large stress, ample movement, smooth and trustworthy managing and flexible operation, as well as straightforward upkeep, which is “a shining star” among comparable merchandise.

  1. CZPT system

CZPT technique of WLQ jetting equipment is revealed in the diagram.
The entire program is made up of large strain pump, relief valve, basic safety valve, foot valve, drinking water gun, enter-return flexible hose, h2o tank and distribution box. During working hours, clean h2o injects into water tank by means of adaptable hose, and then enters the reduced pressure chamber of pump fluid end via imbibing filter, imbibing versatile hose and imbibing end valve. Substantial pressure water is transported to workplaces soon after many segments of large stress hose. There are two types of functioning situations:
Issue one: It is controlled by the foot valve (water gun is not utilised). Such condition is generally used for the cleansing of pipe partitions. Foot valve is utilized to handle the swap.
Issue 2: It is controlled by water gun with switches (foot valve is not utilized). This sort of situation is generally utilised for the cleansing of rusty and filthy floor, as nicely as standard washing. Water gun is utilized to manage the change.
A reduction valve is deployed at the large-force outlet of the pump, to alter the genuine operating strain. Excessive h2o shall return to drinking water tank by way of the overflow port at relief valve and liquid return pipe. Pump protection valve is also deployed, which can be opened immediately when the pumping pressure is elevated due to sudden elements, in order to protect the pump and motor in opposition to shockproof strain gauge and exhibit the functioning force.
three. Structural description
3.one Jetting machine
Jetting machine is a system that can transform drives of electric powered motor or diesel engine to high stress drinking water fluid strain vitality. WLQ cleanse drinking water pump belongs to horizontal a few-plunger reciprocating higher-pressure pump.
Structures of the pump you should see the diagram. It largely consists of housing assembly, pump head assembly, coupling, bottom bracket, and electric powered motor or diesel engine.
Three-phase four-pole AC motor or diesel motor can generate the rotation of a few toss crank shaft through coupling and equipment reducer. It can also act on the connecting rod and slide block system, make slide block reciprocates in the box slipway, plunger is also driven to do reciprocating motion. When the plunger is retracted, vacuum is fashioned in hydraulic chamber. At this time, drinking water self-cleaning tank enters the hydraulic chamber by means of fluid versatile hose, dispensing tube and top open suction valve. When the plunger is relocating forward, suction valve closes off. The water is pressurized, the drain valve is opened, and becoming output outward by means of high strain fluid collection block.
Tank factors: Tank is the bearing human body of pump, which is manufactured of cast iron with higher strength. One particular of its sides is established with gear box. A pair of gears within the box is made of large high quality structural alloy metal, with difficult-tooth-floor of high precision soon after grinding and specific heat treatment method. It has the characteristics of clean rotation, low sounds and exceptional use resistance. The crankshaft is manufactured of alloy steel, and crank surface hardness with large toughness can be reached after specific warmth remedy. Connecting rod massive end is lined with higher tin aluminum bearing bush, with outstanding use resistance. Connecting rod big end moves in the crankcase.
Pump head assembly: Specifics of pump head assembly please see the diagram. A few separated cylinder liners have changed the traditional block pump heads and three large-strain metal sleeves. These kinds of framework can essentially fix the simply-harm link among primary structural pump head and higher strain metal jacket, which may possibly trigger pump head cracking if not repaired. 3 divided heads have drastically simplified the upkeep disassembly, and diminished labor intensity. Piston alloy floor is handled with unique alloy, in order to enhance the primary hardness, wear resistance and corrosion resistance. Plunger and slider are connected by stress block, semi-toroidal, nut and locking screw. During the use approach, changes in the axial gap and screw loose must be paid out consideration to. Plunger is sealed with imported packing rectangular ring, with more time seal lifestyle. None cross-hole assembly framework (see diagram) is used on the mixture valve, which can comprehend flexible startup, dependable sealing, and resilient existence.
three.2 Aid valve
Purpose:
Aid valve is an critical element of the hydraulic system, whose function is to guarantee the procedure of operating pipeline underneath preset pressure. The whole stream of the pump is immediately divided into two parts when passing via the reduction valve, 1 is utilised by water gun or a assortment of components the excessive circulation shall return to the tank, and maintain a continual stress.
Construction and procedure principle:
Pilot operated compound-reduction valve is utilized. It composed of pilot valve and primary valve.
Pilot valve element is linked with the again liquid chamber of major valve via the centre gap, also connects to P port in stress chamber by way of two choke plug holes inside of the main valve factor chamber. In this way, pipeline stress modifications of working pipeline can replicate to the pilot valve element. When adjusting the pilot valve spring, force in between choke plug and pilot valve will increase, ensuing in force in the operating chamber. Alter the doing work stress repeatedly right up until ideal and steady operating pressure is acquired. Beneath the circumstance there is no pressure amongst choke plug and pilot valve, the working pressure shall be zero.
3.three Safety valve
The part of security valve is to carry out overload defense on pump station, i.e. the pressure relief can be commenced instantly when the pump force is improved thanks to surprising reasons.
Framework is proven in the diagram. One particular end of the valve is linked with substantial strain chamber, when the stress exceeds a predetermined value, hydraulic power shall struggle towards the spring pressure to open up the valve and launch force. CZPTly, the strain of protected valve shall be altered to one hundred ten% of the functioning strain. The nut is fastened after the adjustment to stop loosening.
No subject contemplate from the risk-free procedure of pump station, or from the protection considerations of personnel, the established up of protected valve ought to be taken into account.
