- Composition and Overview of WLQ70/70 Jetting CZPT
- WLQ80/one hundred jetting equipment is Company’s mature and steady solution, such as the system, engineering design and style of force handle and protecting components, stock control of supporting parts, item production, solution tests, packaging and shipping and delivery, submission and acceptance , specialized companies, delivery usage and on-website guidance.
WLQ jetting machine is composed of high strain pump, motor, coupling, tri-star starter control box, aid valves and protection valves, etc. It is a required servicing equipment to conduct industrial cleansing on the rusty and soiled area of objects. This equipment adopts divided head of cylinder liner (nationwide patent, patent No. ZL 95 241067.2), and is characterized by large force, sufficient flow, sleek and trustworthy managing and adaptable procedure, as effectively as straightforward routine maintenance, which is “a shining star” among related products. - CZPT program
- CZPT system of WLQ jetting machine is shown in the diagram.
The complete technique is made up of higher pressure pump, reduction valve, basic safety valve, foot valve, drinking water gun, enter-return flexible hose, drinking water tank and distribution box. During operating hrs, refreshing h2o injects into h2o tank by way of adaptable hose, and then enters the reduced force chamber of pump fluid conclude by way of imbibing filter, imbibing flexible hose and imbibing cease valve. High force drinking water is transported to workplaces right after many segments of large force hose. There are two sorts of functioning circumstances:
Issue 1: It is managed by the foot valve (water gun is not utilised). Such situation is generally employed for the cleansing of pipe partitions. Foot valve is used to handle the swap.
Situation two: It is controlled by h2o gun with switches (foot valve is not used). This sort of situation is typically utilized for the cleaning of rusty and dirty area, as well as common washing. H2o gun is used to manage the change.
A reduction valve is deployed at the higher-pressure outlet of the pump, to change the real functioning force. Extreme h2o shall return to h2o tank through the overflow port at aid valve and liquid return pipe. Pump basic safety valve is also deployed, which can be opened automatically when the pumping force is improved because of to sudden variables, in order to defend the pump and motor in opposition to shockproof stress gauge and screen the operating force.3. Structural description
three.1 Jetting equipment
Jetting device is a gadget that can convert drives of electric powered motor or diesel motor to substantial pressure drinking water fluid force strength. WLQ thoroughly clean water pump belongs to horizontal a few-plunger reciprocating substantial-pressure pump.
Constructions of the pump remember to see the diagram. It mostly is made up of housing assembly, pump head assembly, coupling, base bracket, and electric motor or diesel motor.
A few-section 4-pole AC motor or diesel engine can drive the rotation of a few toss crank shaft through coupling and gear reducer. It can also act on the connecting rod and slide block system, make slide block reciprocates in the box slipway, plunger is also pushed to do reciprocating movement. When the plunger is retracted, vacuum is shaped in hydraulic chamber. At this time, water self-cleansing tank enters the hydraulic chamber via fluid adaptable hose, dispensing tube and best open up suction valve. When the plunger is shifting ahead, suction valve closes off. The drinking water is pressurized, the drain valve is opened, and getting output outward via higher pressure fluid assortment block.
Tank factors: Tank is the bearing body of pump, which is produced of solid iron with higher power. One of its sides is set with gear box. A pair of gears inside the box is produced of higher top quality structural alloy steel, with tough-tooth-area of higher precision soon after grinding and particular heat treatment method. It has the attributes of sleek rotation, minimal sound and excellent dress in resistance. The crankshaft is manufactured of alloy metal, and crank floor hardness with substantial toughness can be attained right after specific warmth treatment. Connecting rod large stop is lined with high tin aluminum bearing bush, with exceptional put on resistance. Connecting rod massive conclude moves in the crankcase.
Pump head assembly: Information of pump head assembly please see the diagram. Three divided cylinder liners have changed the traditional block pump heads and a few substantial-pressure steel sleeves. This sort of composition can basically resolve the very easily-injury link in between primary structural pump head and large strain steel jacket, which might cause pump head cracking if not fixed. A few separated heads have greatly simplified the routine maintenance disassembly, and decreased labor intensity. Piston alloy floor is dealt with with unique alloy, in get to increase the major hardness, dress in resistance and corrosion resistance. Plunger and slider are linked by stress block, semi-toroidal, nut and locking screw. In the course of the usage method, adjustments in the axial hole and screw unfastened must be paid attention to. Plunger is sealed with imported packing rectangular ring, with more time seal lifestyle. None cross-hole assembly construction (see diagram) is utilised on the combination valve, which can comprehend versatile startup, reliable sealing, and tough existence.
three.two Aid valve
Function:
Aid valve is an important factor of the hydraulic technique, whose function is to make sure the operation of doing work pipeline underneath preset pressure. The whole flow of the pump is routinely divided into two components when passing via the reduction valve, a single is utilized by drinking water gun or a range of accessories the extreme stream shall return to the tank, and sustain a continual stress.
Framework and procedure basic principle:
Pilot operated compound-relief valve is utilised. It composed of pilot valve and main valve.
Pilot valve element is linked with the back liquid chamber of primary valve through the heart gap, also connects to P port in force chamber by means of two choke plug holes inside the main valve aspect chamber. In this way, pipeline strain changes of working pipeline can reflect to the pilot valve aspect. When changing the pilot valve spring, strain amongst choke plug and pilot valve will enhance, resulting in strain in the doing work chamber. Alter the doing work force constantly until finally suited and stable functioning strain is obtained. Under the circumstance there is no force amongst choke plug and pilot valve, the doing work force shall be zero.
three.three Basic safety valve
The position of basic safety valve is to perform overload defense on pump station, i.e. the strain aid can be started instantly when the pump force is enhanced thanks to unexpected causes.
Framework is shown in the diagram. 1 conclude of the valve is connected with high force chamber, when the strain exceeds a predetermined value, hydraulic power shall battle from the spring power to open up the valve and release force. CZPTly, the strain of secure valve shall be altered to one hundred ten% of the working stress. The nut is mounted following the adjustment to avert loosening.
No matter take into account from the safe procedure of pump station, or from the protection issues of staff, the established up of safe valve ought to be taken into account.three.The technical parameters
