1, note that the quality of the sheet suction truck, vacuum tightness, the difference is likely to cause problems tank material deformation.
Option 2, the vacuum package, the pressure capability and temperature difference perceived.Domestic kit devaluation Veyron series.
3, the gravity valve selection, according to the local operating environment, temperature, etc. selected.

Description of main components
Tank cross section is elliptical, Wuhan Q235A tank with high truckbon steel plate, the thickness of 6mm, inner solder prescribe swash plate to reduce the impact, the reinforcing ring the tank body, the head has a discharge gate in the tank o the top of the manhole is provided and is mounted with moisture separators and boom assembly.Bottom of the tank with a tank foot secured together by U-bolts to the chassis.
2, the oil separator
Mainly by the oil separator cover, the separator body, drain plug, positioning sleeve, a separator and other components.It pumps out from the oil separator, the oil flow back to the pump through the tubing, pump lubrication, the gas vented through the four-way valve.
3, moisture separator
Moisture separator mainly composed of an upper cover, a compression spring, in the sleeve, outer sleeve, the core and other components.It is used to separate the gas from the tank body.Automatic separation of water flow back into the tank, the gas enters the vacuum pump through the four-way valve.
4, boom assembly
Boom holder assembly is mainly composed of a boom, absorption property management, guide property management, etc. with weights, a tool was pumped fluid.
5, gas trucktridge
Manifold assembly is mainly composed of the water-gas separator, a vacuum pump, a four-way valve, the crude oil separator, oil separators, piping and other components.When the vacuum pump starts working, position four-way valve handle to the actuating plate "draw" the water vapor through the gas separating tank allows water and gas separation, the water flows back to the tank automatically, the four-way valve into the vacuum pump through the gas discharge the crude gas enters the separator, then the gas will pump the oil into the oil separator through an oil separating means, the gas separated from crude oil by the oil separator by the line back into the oil separator, the gas vented into the four-way valve.(Gas-water separator is a four-way air valve a vacuum a crude oil separator a separator a four-way valve venting)
6, vacuum pump
The main rotor of the vacuum pump, a blade, a shaft, a cam sleeve, housing, etc., the rotational torque from the automotive engine by the PTO shaft and transmitted to the pump.The driver can use the joystick in the cab to achieve opening and closing of the vacuum pump.Lubricating oil pump in the oil separator during operation of the rotor will be in the suction pipe through the circulation lubrication pump body o
7, the liquid level gauge alarms and
An upper body mounted liquid alarm, the head level gauge plate is mounted, to prevent sewage spills.Self-priming from the row of suction convenient, with high vacuum, suction away, and can be used to meet the different users in different environments using.Suction truck according to customer requirements to install sprinkler function, water, manure can be independent points can fecal suction can be watering, a dual-purpose vehicles.
To principle truckburetor suction truck suction truck can work continuously (running), must continuously, not only supplied to the engine fueling, air supply, but also that they are properly mixed, the combustion exhaust gas can also be finished smoothly discharged.To do this, need to be stored in a fuel tank, the fuel tank into the engine, pumps and pipes must have.In order to prevent fuel contamination, the filter needs to be filtered.
Air outcbm air containing dust, into the engine's air filter needs to be filtered.How to clean the air and fuel preparation needed, you need not be a part of a de broken down, that is, suction truck truckburetor.Currently suction truck on a conventional single-stage rotary seals are a vacuum pump by the pump, and the formation of the rotor, the pump housing, rotary vane, slip ring, and a sealing device consisting of a bearing cap, rotor wearing parts, in order to facilitate Removing repair, rotor offset from the turning center to the center of the pump.
Its working principle is eccentric rotor operating in PTO drive, the tank into the compression chamber, when the pressure exceeds a predetermined value of the exhaust port, the compression chamber automatically open, the compressed air is discharged, so that air is drawn incbm the tank, repeated cycle, the vacuum is formed incbm the tank.In order to ensure normal operation of the vacuum pump and avoid contamination, while also producing suction truck mounted oil separator and a moisture separator to filter the compressed hydrotruckbon gas and water vapor.

Water truck tank process measures:
1.Correcting the first stamping member separate units, and then assembled in order from a start point of the solid;
2.Tooling sequence: upper wing web → → → block tank after the tank before plugging → → the intermediate diaphragm blade.Tack weld size of 50 / 200mm, tack welding to fill the crater at the end, to prevent microcracking;
3.After the first fixed point on the blade and the web take by fillet welds, and then finished before welding, after welding can block production, after the upper blade *** weld seam;
4.In order to control the deformation, to take truckve reverse welding, namely: two in the same manner, consistent energy control line;
5.Welding operation to be standardized, especially welding sequence with the welding speed, which can effectively control the problem of excessive local deformation;
6.Tack welding is completed, the whole tire, to release all the Taiqian jig, and the good tack Guankou.
Dimensions suction tank truck quality requirements:
1, a buckling ± 3mm;
2, the axis difference ± 5mm;
3, the local ± 5mm recess;
4, roughness ± 2mm;
5, the height difference between the weld machining + 1mm;
6, vertical and horizontal cross-seam is not less than 200mm;
Suction truck maintenance:
1, we must first pay attention to frequent washing, not too often, but so easy to damage the paintwork suction truck.
2, when the truck wash to use clean water, or sewage in the sand will scratch the paint.
3, dedicated to a clean washing towels, towels generally strong friction, it is easy to damage the paintwork of the suction truck.
4, truck wash as far as possible in a cool ventilated place.
5, when the truck wash to be noted that some of the water suction truck to do the work member, such as speakers, lights, etc., in order to avoid fog lamp failure or the like horn.
6, in the summer after suction truck driving do not wash immediately to avoid engine damage, suction truck should wait until the temperature down further.
