308, the top of the pump housing is equipped with oil gas tube socket 309, and check ball 310 is equipped in vacuum tube base, and check ball 310 is bakelite or pure timber
Matter prevents the fluid in vacuum line from driving in the wrong direction, damages vacuum.The turning moment of engine passes to main shaft by Hooks coupling universal coupling
305.Driver can manipulate vacuum pump in driver's cabin.The lubrication of vacuum pump is in rotor operation process by oil gas two
Oil in secondary separator is by carrying out circulation lubrication in oil pipe suction pump body.
In above-described embodiment, safety valve 105 is any equal in weight lever, spring or pulse type safety valve
Can, operating pressure setting value is 0.3 ~ 0.7Mpa, and when pressure is more than setting value in tank of sewage suction truck, safety valve action will be pressed
Power release, avoids pressure inside the tank excessively high, seal failure causes splashing accident.
The working principle of the invention be it is such, when suction-type sewer scavenger need to aspirate dirt, four-way valve handle is gone into mark first
The position of board " suction ", then makes vacuum pump work, after about 40 seconds, negative pressure is generated in tank body, inhaled object will pass through suction pipe certainly
It is dynamic to enter in tank.When dirt need to be drained, four-way valve handle is gone to the position of label " row ", by the rotation of vacuum pump, is made
Positive pressure is generated in tank, is acted on liquid level, liquids, which will pass through, inhales property management discharge, specific steps are as follows:
1, go out Chinese herbaceous peony to prepare
(1) operator's health, the operation and maintenance for being familiar with this powerful sludge vehicle require, and specially trained；
(2) sufficient fuel, lubricating oil, lubricating grease and hydraulic oil are had；
(3) it checks battery, to there is sufficient electricity, it is ensured that smoothly start when going out vehicle；
(4) start engine, check oil pump operating, notice whether its operating is normal；
(5) check whether powerful sludge vehicle equipment situation is normal, around whether there is or not the factors for influencing trouble free service.
2, the manipulation of power takeoff
By car engine, when air pressure is raised to 0.6MPa or more, clutch pedal is depressed, then press power takeoff electric-controlled switch, taken
Power device hangs shelves.When automobile is advanced, it is necessary to gear lever are placed on neutral position, allow automobile slide, then depress clutch pedal side
Otherwise engageable power taking can break engaging tooth.Have to be off power takeoff after work, the separation of power takeoff can in traveling with
When depress clutch pedal press again control switch completion.
This step points for attention: when vacuum pump is not required to work, forbid engaging power takeoff.
3, pumping operation
Dirt sucking tube is inserted into pond first, then four-way valve handle is gone to the position of label " suction ", then engaging power takeoff makes very
Empty pump work, tank body is interior to generate negative pressure, and inhaled object will pass through suction pipe automatically into tank.It is observed by tank level meter specified
Behind position, so that vacuum pump is stopped working at once, takes out suction property management and be put into case.
4, operation is discharged
Four-way valve handle is gone to the position of label " row ", then engaging power takeoff makes vacuum pump work, positive pressure is generated in tank body,
Dirt depended on pressure is discharged from property management is inhaled.New car after a period of use, can generate siltation in tank, at this moment row on rear side of openable tank body
Door is put, siltation is cleared up away.
5, door is discharged
When opening discharge door, manual locking device is first unscrewed, then manipulates hydraulic valve bank again, pushes discharge door open.Close discharge door
When, hydraulic valve bank is first manipulated, then screw manual locking device, lock discharge door, discharge terminates.
Embodiment described above is only purpose, the technical scheme and beneficial effects for the present invention will be described in detail and the tool chosen
Body example, but should in no way limit protection scope of the present invention, it is all without violating the spirit and principles of the present invention, made
Various modifications, equivalent replacement and improvement, should all fall under the scope of the present invention.
