I Fully automatic vacuum assisted high suction head hydraulic self-priming flood control pump Product Overview
Although the motor of the former self-priming pump can be replaced with a hydraulic motor, the self-priming pump needs to be filled with water every time the self-priming pump is started, and the self-priming time is long, and the water inlet pipe cannot be too long. If the pipe is too long, due to too much air content in the pipe When the self-priming pump runs for a long time, the water in the pump chamber will cavitate after the water temperature rises because the impeller drives the friction circulation between the water and the pump chamber at a high speed inside the pump chamber, so that the self-priming capacity will become lower and water cannot be sucked in.
Full automatic vacuum auxiliary hydraulic self-priming pump Equipped with vacuum pump; Self priming pump and vacuum pump The hydraulic motor is a swashplate plunger motor, his High working efficiency, high rotating speed, high power, etc. The power of the full-automatic vacuum auxiliary hydraulic self-priming pump can use the engine of pickup truck and box truck as the power to refit the hydraulic power station, fix the full-automatic vacuum auxiliary hydraulic self-priming pump on the pickup truck or box truck, and extend the horizontal distance of the self-priming pump inlet pipe to suction two hundred The water inlet of self-priming pump with a distance of more than meters and a large flow rate, for example, is delivered from the factory two When there are more than outlets, if we don't want to use too many water pipes, we can use a bulkhead to block off the excess water pipes. It can also be used if only one outlet is used at the inlet and outlet, or we can separately configure a traction hydraulic power station system to drive the hydraulic system of the full-automatic vacuum assisted hydraulic self-priming pump ， The full-automatic vacuum auxiliary hydraulic self-priming pump can also be installed on the remote control crawler robot or amphibious vehicle as a slave pump truck, and the self-priming pump can be used before pumping The motor and the vacuum pump hydraulic motor rotate and work at the same time. When the water level of the self-priming pump reaches the pump body Upper water tank After, via level Float position to control the hydraulic switch valve through Cut off the operation of the vacuum pump hydraulic motor, and all hydraulic power is supplied directly Large self-priming pump Hydraulic motor.
II Full automatic vacuum assisted high suction head hydraulic self-priming flood control pump The working principle is as follows ：
one Connect the oil supply pipe provided by the power station with the oil inlet pipe assembly of the hydraulic self-priming pump, and connect the oil return pipe of the power station with the main pipe of the oil return port.
two When the power station is started, the hydraulic oil goes to the diverter valve switching assembly through the main pipe at the oil inlet to supply oil to the self-priming pump motor and the vacuum pump respectively. The vacuum pump and the self-priming pump run together at the same time to pump water. The self-priming pump can idle for a long time because the seal oil chamber is filled with lubricating oil When the water is pumped up from the inlet of the self-priming pump, the floating ball sensor will float. At this time, the signal will be fed back to the electromagnetic switch valve to close the oil supply of the vacuum pump so that the vacuum pump will automatically stop running. A check valve is set in the outlet of the self-priming pump
three The pressure relief pipe of the self-priming pump hydraulic motor and the vacuum pump hydraulic motor are both connected with the return oil collector box, which greatly reduces the disadvantages of the previous hydraulic system that requires multiple pressure relief pipes to return to the main oil tank, or the occurrence of a series of failures caused by the confluence of the pressure relief pipe and the return pipe.
four The oil return pipe of the self-priming pump hydraulic motor and the oil return pipe of the vacuum pump hydraulic motor also return to the oil return collector box in a unified way to merge in this way, which is also to reduce the pressure holding phenomenon of the high pressure caused by the confluence, which will damage the motor shaft seal or oil pipe. Then return to the oil tank of the power station through the main pipe of the enlarged oil return port, so as not to cause the hydraulic motor to leak oil due to pressure holding and shaft seal damage.
five When air is sucked into the water inlet pipe of the self-priming pump, the floating ball sensor in the water tank will return to the low position, and then the feedback signal will be sent to the solenoid switch valve to open the oil supply pipe of the vacuum pump hydraulic motor to make the vacuum pump run to help the self-priming pump pump negative pressure, for example, when pumping low water level media Or when the inlet pipe has a slight air leakage, the vacuum assist * can help the self-priming pump not to destroy the vacuum due to the suction of air, resulting in the phenomenon of no water.
six When the inlet and outlet of the self-priming pump are divided into multiple branches, when the flow of the self-priming pump is reduced and the suction pipe of the self-priming pump wants to extend the pumping distance, we can also plug several inlet and outlet pipes and use only one inlet to pump water remotely, for example, the working conditions that some equipment cannot access * can extend the inlet pipe for pumping operation In addition, our self-priming pump has strong self-priming capacity, and the inlet pipe can be extended two hundred Pump water at a distance of more than meters.

4、 Performance parameters of automatic vacuum auxiliary hydraulic self-priming pump
Flow of 100-3000m3/h and lift of 10-60m can be customized according to user requirements.
We can also customize the remote control caterpillar hydraulic drainage pump station, or the hydraulic self-priming pump drainage pump station integrated with the power station and the crawler car.
