What is the acceptance criteria for sweepers?
Before purchasing the applicable road sweeper, it is necessary to carefully examine it before it can be accepted. If the work of acceptance is not done well, there will be frequent breakdown after the road sweeper is sent back. After purchasing a road sweeper , it is necessary to carry out a comprehensive inspection of the vehicle. In the acceptance of the timely detection of existing problems, so as not to bring much trouble in the subsequent use.
When carrying out the inspection of the road sweeper, it is still necessary to check some of the functions of the next sweeper, and in turn check the chassis, but mainly depends on whether the chassis of the sweeper is a backlog chassis, because The price of the chassis of the road sweeper is cheaper than the price of the new site. Therefore, if the road sweeper uses a chassis, the price should be much lower.
Check the sweeper chassis is not for Yaku, we should look to cloud the case of rust chassis date of manufacture, as well as the chassis. This is also the situation where the rubber hose of the engine has softened. Pressurizing the chassis does not affect the quality of the car. It just means that the price is relatively cheaper. Then check whether the engine of the sweeping vehicle is running steadily. Press the hand gently on the engine of the sweeper to feel the amplitude and frequency of the jitter, and then check the sound of the engine. The sound of the engine is the method of choice. The next step is to check if the working conditions of the throttle, brake, steering wheel, clutch, and gearbox of the road sweeper are normal. The last step is to check each of the sweeps. Function is not normal. The flexibility of the operation switch and some cleaning effects of the sweeper on the road, if there is no problem in the inspection, then you can make the transfer of the sweeper, that is to say from the vehicle instruction manual, chassis certification, sweep Vehicle certification, vehicle warranty manuals, invoices, etc. (Text / Sun Ni)
The forced circulation pump does not rely on the centrifugal force of the impeller to the liquid, but uses the thrust of the rotating impeller blades to make the sent liquid flow along the direction of the pump axis. When the pump shaft is driven by the motor to rotate, because the blade has a certain helix angle with the axis of the pump shaft, a thrust (or lift) is generated on the liquid, and the liquid is pushed out and discharged along the discharge pipe. When the liquid is pushed out, a partial vacuum is formed at the original position, and the liquid outside will be sucked into the impeller along the inlet pipe under the action of atmospheric pressure. As long as the impeller keeps rotating, the pump can continuously suck in and discharge liquid. The forced circulation pump works by using the horizontal thrust along the direction of the pump axis generated by the rotation of the impeller, so it is also called a horizontal axial flow pump. Mainly used in the evaporation of diaphragm method caustic soda, phosphoric acid, vacuum salt production, lactic acid, calcium lactate, alumina, titanium dioxide, calcium chloride, ammonium chloride, sodium chlorate, sugar, molten salt, paper, waste water and other industries. Concentration and cooling, in order to improve the production capacity of the equipment, increase the heat transfer coefficient of the heat exchanger for forced circulation. Therefore, it can also be called an axial flow evaporative circulation pump.
