Product Details

The tri - screw pump is a kind of high efficiency, low noise, wide application and long service life, which is specially designed and developed by our company in response to market and customer needs. It is especially suitable for the transportation of solid particles and non - corrosive medium with viscosity above 380cst ~ 460cst. The product is designed and manufactured in accordance with GB / T10886 - 2002.


I. structural characteristics

1. HSDF 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 driven by hydraulic force. There is no contact between the main and follower screw, so there is no wear on the screw;
3. the pump body is double layer structure, the interlayer can heat the medium in 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. the product structure is simple, the mechanical efficiency is high, the maintenance is convenient, the self-priming ability is

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 necessary cavitation allowance NPSHr value of the pump is found out according to the pump specifications, rotational speed and viscosity.
5. if the necessary cavitation allowance NPSHr value of the pump is less than the NPSHa value of the pipeline device cavitation allowance, 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 specification, Under the viscosity, the flow rate and shaft power N _ 1 of this specification pump under working pressure P are found out, 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
