I. structural characteristics
1, HSD series three screw pump is a kind of advanced quantitative volume pump, which is made up of special shape helical surface.When working, the active screw rotates under the drive of the prime mover, and its moving seal chamber conveys the liquid from the inlet to the outlet continuously and continuously without pulsation along the axis.In the whole transportation process, because the volume of the seal cavity does not change and the medium is not compressed, the pump runs smoothly, has low noise, small vibration and stable flow.

2, the main and follower screw adopt axial low pressure balance.The main and follower screw is in the tension state in operation, so the screw is not easy to deform; the follower screw is rotated by hydraulic force There is no contact between the main and follower screws, so there is no wear on the screw;

3, the pump body is a double layer structure, and the interlayer can heat the medium inside the pump through the heating medium;

4, the direction of the inlet and outlet of the pump can be changed according to the requirements of the user, There are back in and out (base type, in and out, left in and out, right in and out, etc.) (see code name for details, easy to use on site.

5, product structure is simple, mechanical efficiency is high, maintenance is convenient, self-priming ability is strong, service life is long

4. Selection steps and matters needing attention
1. First of all, it is necessary to accurately understand the actual working parameters of the pump, such as pressure, flow rate, the working temperature of the medium, the viscosity of the medium at the working temperature, and the lubricity of the medium.Corrosion, etc. 

2. According to the viscosity of the medium at working temperature, select the rotation speed of the pump, the general viscosity is less than 300mm / 2 / s, and select n=1450r/min is more suitable. When the viscosity is greater than 300mm / 2 / s, please carefully consider the necessary cavitation allowance of the pump, To avoid pump vibration; 

3. from the pump performance table, according to the required flow rate, pressure and other parameters of the initial selection of pump specifications;

4. from the pump On the necessary cavitation meter P15), the NPSHr value of the necessary cavitation allowance of the pump is found out according to the pump specifications, rotational speed and viscosity. 

5. if the NPSHr value of the necessary cavitation allowance of the pump is less than the NPSHa value of the cavitation allowance of the pipeline device, then the pump type selection is correct.If the NPSHr value of the necessary cavitation allowance of the pump is greater than the NPSHa value of the cavitation margin of the pipe installation, the pump with a large file should be selected or the rotational speed should be reduced, and the NPSHr value should be adjusted again. NPSHr ≤ NPSHa K (general safety margin K = 0.3-0.5m)

6. after selecting the pump specifications, Under the corresponding viscosity, the flow rate and shaft power N _ 1 of this specification pump under working pressure P are found out from the table, and the motor power N _ 2N _ 2 ≥ K _ N _ 1 is selected.

7. After the user selects the pump, according to the pump specification and the matching size of the motor, the foundation construction design is carried out, and the inlet and outlet pipeline must match the pump inlet and outlet.

8. if you need it, our technical department can type it for you.You are required to provide the following flow rate Q medium working temperature T pump inlet pressure (or vacuum) P1 pump outlet pressure P2 operating temperature medium viscosity v medium characteristics matching requirements


Applied industry enumeration

Important Note on Type selection and configuration of Three-screw pump Group and matters needing attention in using the Machine: (for reference of Design Institute and site installation, use and maintenance personnel)
No medium idling, please add lubricating medium or conveying medium before starting.
All sundries and soldering slag are strictly forbidden to enter the pump cavity, and the cleanliness of the pump cavity and pipe must be maintained.
Do not use pipe filter or Y-type filter device. Please ensure that the filter area is 20-30 times of the pump inlet diameter section area.According to the cleanliness of the medium, the mesh number of the filter net is correctly configured.
It is strictly prohibited that the inlet and outlet pipelines of the pump do not match with the inlet and outlet pipelines of the pump. The pipe diameter configuration must be consistent with the inlet and outlet flow path of the pump. It is necessary to avoid cavitation or self - suction. The pipeline is too thin to cause cavitation, thus causing the pump to work in a state of not being saturated, leading to a decrease in the flow pressure of the three - screw pump group and even abnormal vibration and noise, which can cause severe damage of the card pump and the screw pump for a long time,
The installation height of the three-screw pump must fully consider the cavitation condition of the pump and the self-priming capacity of the pump (the cavitation allowance is related to the viscosity speed of the medium and the lead of the screw).
Since the functions of packing, transportation, lifting, loading and unloading and pipe bolt fastening may easily cause the original factory location of the pump to change or even seriously misposition, so after the installation and fixing of the pipe system of the three-screw pump group, Be sure to recheck the coaxiality of the three-screw pump and the motor before starting the car.
It is forbidden to start the machine when the back pressure is started and the inlet valve is closed.
It is strictly prohibited to start rotation in the direction that does not conform to the pump rotation mark.
Double pumps must be connected in parallel with one-way valve at the outlet and inlet of the pump to prevent the reverse of the three-screw pump driven by the medium backflow.
Free adjustment of safety valve bolts is strictly prohibited. The safety valve is only used to protect the safety of the pump and the matching of the motor power with the working state of the pump, and is strictly forbidden to be used as the pressure regulating valve and the relief valve.
