  1. Composition and Overview of WLQ42/250Jetting CZPT

WLQ80/a hundred jetting device is Firm’s experienced and steady merchandise, which includes the technique, technologies layout of pressure manage and protective components, stock handle of supporting elements, merchandise manufacturing, solution testing, packaging and shipping and delivery, submission and acceptance , technical companies, shipping use and on-site advice.
WLQ jetting machine is composed of high force pump, motor, coupling, tri-star starter control box, reduction valves and safety valves, and so on. It is a essential servicing gear to perform industrial cleaning on the rusty and soiled floor of objects. This device adopts divided head of cylinder liner (nationwide patent, patent No. ZL ninety five 241067.2), and is characterized by high pressure, adequate circulation, clean and dependable operating and versatile operation, as effectively as simple maintenance, which is “a shining star” amid equivalent merchandise.

  1. CZPT system

CZPT method of WLQ jetting device is demonstrated in the diagram.
The whole program is composed of substantial strain pump, reduction valve, safety valve, foot valve, h2o gun, enter-return versatile hose, drinking water tank and distribution box. During functioning hours, new h2o injects into water tank by means of adaptable hose, and then enters the minimal pressure chamber of pump fluid end by means of imbibing filter, imbibing adaptable hose and imbibing stop valve. Large force water is transported to workplaces after numerous segments of high force hose. There are two sorts of functioning conditions:
Situation 1: It is controlled by the foot valve (water gun is not utilised). This kind of situation is generally utilised for the cleansing of pipe walls. Foot valve is employed to management the change.
Issue 2: It is managed by water gun with switches (foot valve is not employed). This kind of problem is typically utilised for the cleaning of rusty and filthy area, as well as basic washing. Drinking water gun is used to management the switch.
A relief valve is deployed at the substantial-strain outlet of the pump, to change the actual running strain. Excessive drinking water shall return to h2o tank through the overflow port at aid valve and liquid return pipe. Pump protection valve is also deployed, which can be opened immediately when the pumping stress is increased due to sudden aspects, in get to defend the pump and motor against shockproof force gauge and exhibit the working pressure.
3. Structural description
three.one Jetting machine
Jetting machine is a gadget that can convert drives of electrical motor or diesel motor to large stress drinking water fluid stress energy. WLQ clean water pump belongs to horizontal 3-plunger reciprocating large-stress pump.
Structures of the pump please see the diagram. It largely is made up of housing assembly, pump head assembly, coupling, base bracket, and electrical motor or diesel engine.
3-period 4-pole AC motor or diesel engine can travel the rotation of a few throw crank shaft via coupling and gear 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 motion. When the plunger is retracted, vacuum is fashioned in hydraulic chamber. At this time, drinking water self-cleaning tank enters the hydraulic chamber via fluid adaptable hose, dispensing tube and leading open up suction valve. When the plunger is transferring forward, suction valve closes off. The h2o is pressurized, the drain valve is opened, and currently being output outward via high stress fluid collection block.
Tank parts: Tank is the bearing physique of pump, which is manufactured of forged iron with higher power. A single of its sides is established with gear box. A pair of gears within the box is made of substantial good quality structural alloy metal, with hard-tooth-surface area of higher precision following grinding and unique warmth therapy. It has the functions of easy rotation, lower noise and exceptional put on resistance. The crankshaft is produced of alloy steel, and crank area hardness with substantial toughness can be accomplished following particular warmth treatment method. Connecting rod big stop is lined with high tin aluminum bearing bush, with superb put on resistance. Connecting rod large stop moves in the crankcase.
Pump head assembly: Particulars of pump head assembly you should see the diagram. Three separated cylinder liners have replaced the traditional block pump heads and a few higher-force steel sleeves. This sort of composition can fundamentally fix the very easily-harm connection among principal structural pump head and higher pressure steel jacket, which may well result in pump head cracking if not repaired. Three divided heads have greatly simplified the servicing disassembly, and reduced labor intensity. Piston alloy surface area is dealt with with particular alloy, in order to boost the principal hardness, dress in resistance and corrosion resistance. Plunger and slider are connected by force block, semi-toroidal, nut and locking screw. Throughout the use process, adjustments in the axial hole and screw free should be paid interest to. Plunger is sealed with imported packing rectangular ring, with lengthier seal life. None cross-hole assembly composition (see diagram) is employed on the mixture valve, which can comprehend versatile startup, dependable sealing, and sturdy lifestyle.
3.2 Relief valve
Purpose:
Relief valve is an essential element of the hydraulic technique, whose role is to make sure the operation of operating pipeline under preset force. The total circulation of the pump is immediately divided into two parts when passing by way of the reduction valve, one particular is employed by drinking water gun or a variety of accessories the abnormal circulation shall return to the tank, and keep a consistent strain.
Construction and procedure principle:
Pilot operated compound-relief valve is used. It composed of pilot valve and primary valve.
Pilot valve element is connected with the back liquid chamber of major valve by means of the heart hole, also connects to P port in force chamber by way of two choke plug holes inside the major valve element chamber. In this way, pipeline pressure changes of working pipeline can mirror to the pilot valve component. When modifying the pilot valve spring, stress amongst choke plug and pilot valve will increase, resulting in stress in the working chamber. Change the doing work force constantly until finally suitable and stable functioning pressure is attained. Underneath the circumstance there is no stress between choke plug and pilot valve, the operating pressure shall be zero.
three.3 Protection valve
The position of security valve is to carry out overload safety on pump station, i.e. the stress relief can be started automatically when the pump stress is improved because of to surprising motives.
Structure is demonstrated in the diagram. 1 stop of the valve is connected with large pressure chamber, when the pressure exceeds a predetermined worth, hydraulic pressure shall fight from the spring drive to open up the valve and release stress. CZPTly, the pressure of protected valve shall be adjusted to a hundred and ten% of the working pressure. The nut is fixed soon after the adjustment to avoid loosening.
No issue contemplate from the risk-free operation of pump station, or from the safety issues of employees, the set up of risk-free valve ought to be taken into account.
