â— Attentions on Sewage Pumps (1) Keep the vacuum pump at a suitable speed The vacuum pump speed is too high, and the rotor heat is increased. If the rotation speed is too low, it will cause additional impact on the dispatcher and components, which will affect the service life. In order to achieve a suitable working speed, please adjust the best position of the hand throttle in advance according to the pump type.
(2) Self-unloading cans on flat ground;
The unloading of the tank on an inclined road surface will cause distortion of the components and cause failures, and it may cause roll-over accidents.
(3) Open the tank after the unloading can open the tank door:
Before releasing the mud from the unloading tank, the locking bolt should be loosened and the rear tank door should be lifted to the required angle. When the tank is full, it is forbidden to lift the tank body with the rear tank door closed. Otherwise, there is a risk of overturning.
(4) When the oil pump and the vacuum pump take power, the engine idles and the clutch pedal is fully depressed. After the power take-off switch is turned on, slowly release the clutch pedal.
(5) The vacuum pump and the oil pump are stopped when the car is running.
(6) The vehicle must not inhale material larger than the diameter of the hose and transport waste oil and hazardous materials.
(7) Support rods and safety stops must be used when the unloading tank is lifted into the bottom of the tank or during overhaul.
(8) When transporting dirt, the vehicle must be driven at a moderate speed and at a slow speed, and no sharp turning or sudden braking should be allowed because the center of gravity of the anti-wave board is not high.

2. The choice of vacuum kit, the pressure capacity and the perception of temperature difference. The domestic kit debuts Veyron products.
3, after the choice of self-flow valve, according to the local operating environment, temperature and other choices.
â— Knowledge of the suction truck maintenance knowledge Before the suction truck is installed, the pump is installed under the frame of the car with a suitable frame, angle iron, and clamp. The position of the pump is determined by the output shaft axis of the power takeoff. Do not interfere with the components of the car frame as close to the power take-off and beam as possible. The connection inclination between the pump shaft and the power take-off output shaft must not exceed 7 degrees.
Suction pipe system piping is strictly prohibited from leaking, otherwise it will affect the degree of vacuum. The exhaust pipe should also be free from leakage so as to avoid vacuum oil discharge, pollute the environment and waste energy.
Since this pump is an oil seal pump, it is necessary to maintain sufficient number N32 mechanical oil during normal rotation, and in the winter cold season in northeastern and northwestern areas, 32# refrigeration oil should be used. The oil will act as a seal gap and lubrication, but the oil in the pump will also be affected. When the exhaust gas is taken out of the pump, a primary and secondary oil-gas separator must be installed on the outside of the exhaust port to fully separate the oil and gas. The oil is recovered and then used by the pump, and the gas is discharged into the atmosphere so that the pump can run smoothly without pollution. , And energy saving.
Suction truck vacuum suction pump properly installed:
1, the pipeline does not allow the existence of air leakage phenomenon, or suction truck will not work.
2. Suction truck vats must be equipped with spill-prevention devices. Otherwise, the suction truck can easily take the waste sewage into the vacuum pump and damage the entire system.
3. The primary oil-gas separator return port of the suction truck must be connected to the oil return port of the secondary oil-gas separator and the suction pipe must be a rigid pipe or a hard oil-resistant rubber pipe (steel wire braid hose). Thermally deformed plastic tubes are not allowed.
4. When the suction truck is used in the new pump, it should directly add 1-2L mechanical oil No.32 to the pump, and add 32# refrigerating machine oil when it is used in the cold regions of northeast and northwest.
A moisture separator should be installed at the suction port of the pump.
â— Tips on suction truck The suction pump vacuum pump must first work to understand its working principle. The more important work principle is the consideration of the source of power and stability. The vacuum pump power comes from the chassis engine. The engine is transmitted to the vacuum pump via gearboxes, power take-offs and driveshafts. During the suction operation, the vacuum pump extracts the air in the sealed tank to form a negative pressure. The atmospheric pressure outside the tank is used to press the dirt into the tank through the suction pipe. When the sewage is drained, the vacuum pump will put atmospheric pressure outside the tank into the tank and use the air pressure to discharge the dirt out of the tank (the vacuum pump's continuous working time generally does not exceed 30 minutes).
The flow sequence of the air flow in the air path is as follows: When the air is sucked, the vacuum pump sucks the air with a certain humidity in the tank into the water and gas separator, where the water is separated and flows back into the tank. The gas enters the vacuum pump along the pipeline through the four-way valve. Air intake. The pump is mixed with the lubricating oil and is discharged from the exhaust port through the compression chamber. In particular, the mixture is initially separated by the primary filter, and the separated oil flows back to the oil pump. The mixture is further separated by an oil separator and then discharged into the atmosphere through a four-way valve. Manual operation of the four-way valve can change the direction of the air flow, sucking and discharging freely.
When the vacuum pump of the suction truck is completed, it is necessary to formulate a corresponding inspection of the suction truck according to the difference in the strength of each work to ensure the working life of the suction truck and the second work efficiency.
