Rhd Sinotruk Howo 5cbm sewer vacuum Sewage Tanker suction Trucks performs mud suction and sewage suction operations under a high vacuum state, and special attention should be paid to its operation.
Rhd Sinotruk Howo 5cbm sewer vacuum Sewage Tanker suction Trucks is composed of automobile chassis, power take-off, transmission shaft, vacuum sewage suction pump, pressure tank, hydraulic part, pipe network system, real pressure gauge, fecal window, hand washing device, etc., equipped with high power Vacuum sewage pump and high-quality hydraulic system,
The head of the tank body is press-formed at one time, the tank body can be opened back, and the double top is self-unloading. It has the characteristics of high vacuum, large tonnage, high efficiency optimization method, and more extensive use. Kind of sludge in the ditch,
Suction, transportation and discharge of sewage or petrochemical sewage pond sludge. The dirt in the tank can be dumped directly through the back cover. It is used in large, medium and small town sanitation, municipal administration, agriculture, chemical industry, factories and mining enterprises, property communities, etc. department.
1. Operation method of suction and release:
(1) Preparation before suction and release operation
A. Close the back door; B. Observe whether the oil and gas separator of the vacuum pump is correct
(2) Operation sequence
A. Step on the clutch pedal, push the lever of the power take-off box to run the vacuum pump of the sewage suction truck, and then slowly release the clutch pedal;
B. Turn on the alarm switch (in the cab);
C. Pull the hand throttle handle to the maximum position and observe the tachometer to reach 500-600 rpm (adjusted at the factory);
D. Put the four-way valve switch lever in the suction position, and check whether the air discharged from the air pipe is correct, whether the vacuum pump is running with abnormal noise, whether the vacuum gauge is normal, etc.;
E. Remove the dirt suction hose from the vehicle, put it into the mud well, and make the dirt suction hose straight or freely bent. The parking position should be fully considered.
(3) Notes for operation
A. Stones, cotton yarn, leaves and other impurities larger than 50mm will block the straw, so do not inhale it and remove it frequently;
B. When observing the reading of the vacuum gauge to 65-80 kPa, fully open the dirt suction ball valve, the half-open state will easily damage the ring valve core
C. When sucking in sludge, you should move the suction pipe frequently. When sucking in high-viscosity sludge, occasionally suck in air and water to improve efficiency.
2. Sewage discharge method:
After the mud and water are separated, open the drain ball valve, drain the sewage and then repeatedly suck the mud. It can also be pressurized and quickly discharged. The operation method is as follows:
(1) Put the four-way valve switch lever in the "neutral" position, and then put the drain ball valve in the "open" position, the sewage can be discharged by gravity;
(2) Switch the four-way valve to the discharge position, the vacuum pump continues to work, and the compressed air sewage flowing into the side tank will be quickly discharged;
(3) When pressure is drained, the discharge ball valve should be opened first, and then the four-way valve can be moved to the discharge position to avoid excessive pressure in the tank, causing accidents and affecting the seal of the tank door.
