Abstract

Piston pump belongs to pump series products in the water conservancy machinery, at the equipped closed valve seat that has water one-way valve and directional post in body upper end; The transporting water seal of tube is sleeved on the body upper outside, and closed valve seat is contained; Directional post is inserted on the guiding pylon of carrying in the water pipe; Pressure spring is sleeved on the directional post, between guiding pylon and closed valve seat; The water inlet one-way valve is fitted on the cover body sidewall, and the cylinder configuration that seal ring is installed is in the cover body cavity; This water pump structure is simple, and job run is steady, and fault is few, and unit carrying capacity and respective electrical loss-rate rate are low, conserver power source, and operating cost is cheap.

Description

Piston pump
Technical field
The utility model belongs to the pump series products in the water conservancy machinery, mainly is suitable for mobile performance liquid conveying preferably operation and uses.
Background technique
Centrifugal pump, submersible pump be current be used for mobile performance such as clear water preferably liquid carry main pump class type, especially be fit to use in the bigger production of feed flow.But, the submersible pump complex structure, fault is more in the use, and maintenance is also difficult; Component structural designing requirement strictnesses such as the impeller of centrifugal pump and volute, manufacturing technology level is had relatively high expectations; Especially the ratio of the common technical deficiency unit of being reflected in liquid-conveying amount of two kinds of pumps and corresponding power consumption is on the low side, i.e. power consumption is big, has increased operating cost, the waste electric power energy.
Summary of the invention
The purpose of this utility model designs exactly provides a kind of piston pump, reach simplified structure, reduce manufacturing technology level require, significantly saving power, improve the purpose of unit carrying capacity and respective electrical loss-rate rate, reduction operating cost.
Basic design of the present utility model is, at the equipped closed valve seat in body upper end; Transporting water seal of tube suit is fixed on the body upper outside, and with the whole containing of closed valve seat; Install directional post in the closed valve seat upper-end surface, the directional post top guiding pylon plug-in mounting interior with being fixed on the conveying water pipe cooperates, and pressure spring is sleeved on the directional post, axially locating between guiding pylon and closed valve seat; Equipped water inlet one-way valve on the cover body sidewall, the cylinder configuration that has seal ring is in the cover body cavity; On closed valve seat, be equipped with out water one-way valve, so far constitute piston pump.
The utility model is simple in structure, and manufacturing technology level requires lower, and job run is steady, and fault is few, and maintaining is convenient, and carrying capacity is big, unit carrying capacity and respective electrical loss-rate rate height, and saving power, operating cost is low.

Embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.Piston pump comprises equipped the piston 9 of seal ring 8, and the two ends of connecting rod 10 are hinged with piston 9 and driving mechanism 11 respectively, at the equipped closed valve seat 4 of body 7 upper ends sealing; Carry water pipe 1 sealing suit to be fixed on body 7 upper outside, and with closed valve seat 4 whole containings; Install directional post 13 in closed valve seat 4 upper-end surfaces, directional post 13 tops be fixed on the guiding pylon 2 carried in the water pipe 1 movably plug-in mounting cooperates, pressure spring 3 is sleeved on the directional post 13, in the axially locating between pylon 2 and the closed valve seat 4 that leads; Equipped water inlet one-way valve 6 on body 7 circumferential side walls, the piston 9 that has seal ring 8 is configured in body 7 chambeies.On closed valve seat 4, be equipped with out water one-way valve 12.
During operation, the water inlet one-way valve 6 of this pump is placed in the water reservoir 5, all surround by water; The driving mechanism 11 that rotates moves up and down in body 7 through connecting rod 10 driven plunger 9, when piston 9 moves downward, closed valve seat 4 is seated in body 7 upper ends it is sealed under pressure spring 3 effect, go out water one-way valve 12 and also close simultaneously, the clear water in the water reservoir 5 are washed into 6 moments of water one-way valve open and are entered in the chamber, piston 9 top of body 7; When piston 9 moves upward, under hydraulic action, water inlet one-way valve 6 is closed, press water overcomes pressure spring 3 pressure closed valve seat 4 is backed down from body 7 upper ends, a large amount of clear water enters from its gap location fast and carries in the water pipe 7, go out water one-way valve 12 this moment also opens synchronously, and clear water is flowed in the conveying water pipe 1 operation so repeatedly in body 7.
