Abstract
The utility model discloses an anti-freezing water pump, comprising a pump body with a water inlet and a water outlet, a pump seat fixedly connected to the pump body, a pump shaft penetrating the pump seat and driven by a motor, and an impeller arranged on the pump shaft; a heat preservation layer is arranged on the outer wall of the pump body; a protective layer is arranged on the outer surface of the heat preservation layer; the water inlet is horizontal, and a detachable water inlet cover is arranged on the water inlet; the water outlet is vertical, and a detachable water outlet cover is arranged on the water outlet. The heat preservation layer is arranged on the outer wall of the pump body, so the water pump is easy to machine and good in heat preservation effect; the detachable water inlet cover and the detachable water outlet cover are arranged on the water inlet and the water outlet respectively, so that normal use of the water pump can be ensured, and the water pump can be sealed when not in use to further prevent freezing in the water pump body in cold weather; the water pump is convenient and fast to assemble and dissemble, and is economical.
Description
Technical field
The utility model relates to a kind of water pump, belongs to water pump manufacturing technology field.
Background technique
Water pump is being widely used in daily life, agricultural and industrial production, the small-power water pump of existing family expenses, can from 10 meters to 50 meters of the degree of depth well draw water, water lift in the domestic water be widely used, well, also be specially adapted to that small-sized agricultural land is irrigated, water in lawn etc.; But cold snap arrives in the winter time, especially at the night of Cold Winter, temperature is during lower than subzero, in the pump housing, residual part water can freeze in the pump housing, cause water pump to start, and unwitting user start water pump temporarily, can motor damage, damage water pump; For family use, improved undoubtedly living cost, affect people and live normally, the antifreezing measure of therefore carrying out water pump seem particularly necessary.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and the anti-freezing water pump that a kind of high insulating effect is provided, can normally uses under cold snap.
The purpose of this utility model is achieved by the following technical solution: comprise the pump housing with water intake and water outlet, be fixedly connected on pump seat on the pump housing, be located on described pump seat by motor-driven pump shaft, be arranged on the impeller on pump shaft; The outer wall of the described pump housing is provided with a thermal insulation layer; The outer surface of described thermal insulation layer also is provided with a protective coating; Described water intake be oriented substantially horizontal, be provided with a dismountable water inlet lid on it; Described water outlet be oriented vertical direction, be provided with a dismountable outflow cover for water on it.
As preferably, described thermal insulation layer is the polyurethane foamed thermal-insulating layer, and its thickness is 3-8 centimetre.
As preferably, described protective coating is polyethylene layer.
As preferably, described pump housing inwall is connected with a rubber layer by tackiness agent.
As preferably, described water inlet lid and outflow cover for water are made by rubber.
The beneficial effects of the utility model are: at pump housing outer wall, thermal insulation layer is set, easy processing, high insulating effect; At water intake and water outlet, dismountable water inlet lid and outflow cover for water are set respectively, can guarantee the normal use of water pump, also can be sealed water pump when water pump does not use, further prevent from freezing in water pump body under cold snap; There are characteristics convenient to disassembly.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure enlarged view at A place in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: as shown in Figure 1, 2, comprise the pump housing 1 with water intake 5 and water outlet 6, be fixedly connected on pump seat 2 on the pump housing 1, be located on described pump seat 2 by motor-driven pump shaft 3, be arranged on the impeller 4 on pump shaft 3; The outer wall of the described pump housing 1 is provided with a thermal insulation layer 7; The outer surface of described thermal insulation layer 7 also is provided with a protective coating 8; Described water intake 5 be oriented substantially horizontal, be provided with a dismountable water inlet lid 9 on it; Described water outlet 6 be oriented vertical direction, be provided with a dismountable outflow cover for water 10 on it.
When using water pump, take off into water lid 9 and outflow cover for water 10, on pegging graft respectively on water intake 5 and water outlet 6, intake pipe and outlet pipe get final product; When weather cold, and water pump is idle while not using, will intake cover 9 and outflow cover for water 10 load onto water intake and water outlet, complete the sealing to the whole pump housing, prevent that cool ambient air from entering pump body, the thermal insulation layer of the external wall of proportioning pump, can effectively avoid residual part water freezing in the pump housing simultaneously.
When reusing water pump, dismantle and can whether freeze by visually observing in the pump housing through the water outlet of vertical direction into water lid 9 and outflow cover for water 10; Two can directly inculcate a small amount of hot water from the water outlet of vertical direction in the pump housing, further ice sheet or the ice cube in the pump housing.
Shown in, described thermal insulation layer 7 is the polyurethane foamed thermal-insulating layer, its thickness is 3-8 centimetre; Polyurethane foam has certain styling, also can guarantee the insulation effect to the pump housing.
Described protective coating 8 is polyethylene layer.
The described pump housing 1 inwall is connected with a rubber layer 11 by tackiness agent; Prevent from remaining in part water in the pump housing or other media corrosion and the destruction to pump housing inwall.
Described water inlet lid 9 and outflow cover for water 10 are made by rubber, and the utility model preferentially selects rubber to make water inlet lid and outflow cover for water, are on the one hand to guarantee can not cause damage to water intake and the water outlet of the pump housing in the process of dismounting water inlet lid and outflow cover for water; On the other hand, by will intake lid and outflow cover for water of frictional force, be screwed on water intake and water outlet, operate more convenient, even and the phenomenon of water inlet lid and outflow cover for water damage appears, even also can than, obtain alternative easily.
Structure of the present utility model, avoided to the full extent occurring because of the situation of damaging water pump of freezing in the pump housing, indirectly extended the working life of water pump, for home-use or small-sized agricultural land irrigate with for, there are good economical benefit, the wide characteristics of market prospects.
Certainly, above-mentioned explanation is not limitation of the utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation of making, change and add or replace, all should belong to protection domain of the present utility model.
