Description

Technical Field

[0001] The present invention belongs to the technical field of pump bases, and particularly relates to a multifunctional combined base for pumps. Background Art

[0002] A pump is a machine that transports fluids or increases the pressure of fluids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. Pumps can generally be classified into three categories according to the working principle: positive displacement pumps, dynamic pumps, and other types of pumps.

[0003] Through the above analysis, the problems and defects existing in the prior art are as follows:

[0004] (1) Most of the existing pump bases only support the pump, motor or reducer (low-speed positive displacement pumps mostly require a reducer), with single functions.

[0005] (2) Due to the problems of lubricating oil cooling and leakage liquid collection at the power end of the pump, the pump unit has to design and configure a lubricating oil cooling and leakage liquid collection system, resulting in complex pipelines and increased overall dimensions of the pump unit. Summary of the Invention

[0006] In view of the problems existing in the prior art, the present invention provides a multifunctional combined base for pumps.

[0007] The present invention is implemented as follows. A multifunctional combined base for pumps includes:

[0008] A support module, including a base bracket, a pump bottom plate, and a motor or reducer seat, for supporting the pump and the motor or reducer;

[0009] A pump power end oil tank for storing the lubricating oil of the pump;

[0010] A pump cooling water tank for storing the cooling water of the pump lubricating oil;

[0011] A pump leakage liquid collection module for collecting the leakage liquid of the pump;

[0012] An oil and liquid discharge module for realizing the oil and liquid discharge functions by using oil and liquid discharge pipelines.

[0013] Furthermore, the support module includes a base frame, a pump bottom plate, and a support seat for the motor or speed reducer. By welding the pump bottom plate to the base frame and fixing the pump through the threaded holes on the pump bottom plate, the function of supporting the pump is achieved; the positioning and lubricating oil sealing functions of the pump are realized by means of the positioning holes on the pump bottom plate and the O-ring in the sealing groove. By first fixing the support seat of the motor or speed reducer to the motor or speed reducer and then directly connecting it to the pump fixed on the pump bottom plate, after adjustment and alignment, it is welded to the upper plate of the water tank, thus realizing the function of supporting the motor or speed reducer; the above installation, adjustment, and welding processes of the support module not only eliminate the influence of the dimensional and form-position tolerances of the support seat on the alignment of the pump and the motor or speed reducer, reduce the dimensional and form-position tolerance accuracy and processing requirements of the support surfaces of the pump bottom plate and the support seat of the motor or speed reducer, but also ensure the concentricity of the pump and the motor or speed reducer, with flexible transmission, no jamming, low vibration and noise, and reliable operation; significantly reduce the dimensional accuracy and processing cost of the base.

[0014] The pump power end oil tank includes a base frame, a pump bottom plate, an oil tank bottom plate, and a pump body. By welding the pump bottom plate to the upper part of the base frame and welding the oil tank bottom plate to the lower part of the pump bottom plate, and connecting the pump body through the threaded holes, positioning holes, and sealing grooves on the pump bottom plate, the formed pump power end oil tank has the function of storing lubricating oil; the oil tank bottom plate is placed in the cooling water of the pump cooling water tank, and the lubricating oil is directly cooled by the cooling water, with sufficient cooling, having the function of directly cooling the lubricating oil; the bottom of the oil tank is welded with steel plates. Compared with traditional castings, the surface is flat and clean, without casting impurities, the lubricating oil is clean, and the lubrication effect is good, ensuring sufficient lubrication of the transmission parts, reducing power consumption, and improving efficiency; and extending the service life of the transmission parts and improving the product reliability; the temperature rise of the lubricating oil at the pump power end is low, with sufficient lubrication and reliable product operation.

[0015] The pump cooling water tank includes a base frame, a pump bottom plate, an oil tank bottom plate, a water tank bottom plate, and a water tank upper plate. By welding the water tank bottom plate to the lower plane of the base frame, welding the water tank upper plate to the upper plane of the base frame, welding the pump bottom plate to the upper part of the base frame, and welding the oil tank bottom plate to the lower part of the pump bottom plate, the formed pump cooling water tank has the function of storing water; the oil tank bottom plate is placed in the cooling water of the pump cooling water tank, with sufficient cooling, having the function of directly cooling the lubricating oil; the pump seat frame is provided with a cooling water flow-through channel, so that the entire exposed surface of the base conducts heat to the air, and the base anchor blocks conduct heat to the ground, with a large heat dissipation area and good effect, reducing the temperature rise of the lubricating oil.

[0016] The pump leakage liquid collection module includes a pump cooling water tank, a water tank upper plate, and a water injection and liquid collection pipe. By setting a welding joint for the water injection and liquid collection pipe on the water tank upper plate, welding the water injection and liquid collection pipe to the welding joint, and making the lower end of the water injection and liquid collection pipe communicate with the pump cooling water tank and the upper end open, the formed pump leakage liquid collection module has the function of injecting cooling water or introducing pump leakage liquid from the upper end opening of the water injection and liquid collection pipe.

[0017] The oil and liquid drainage module includes an oil drain pipe, a valve, a liquid drain pipe, and a liquid drain plug. The oil drainage function is realized by opening the valve on the oil drain pipe; the liquid drainage function is realized by unscrewing the plug on the liquid drain pipe.

[0018] Furthermore, the base frame is formed by welding 4 channel steels with their openings facing upwards, and the base frame is rectangular.

[0019] Furthermore, the inner vertical plates of the channel steels of the base frame are provided with flow holes.

[0020] Furthermore, the outer side of the short end of the base frame is provided with an oil drain pipe welding hole, and the oil drain pipe passes through the welding hole of the base frame and is welded.

[0021] Furthermore, the lower plane of the base frame is welded with anchor blocks, and the anchor blocks are provided with anchor bolt holes.

[0022] Furthermore, a vertical support rib plate is welded in the middle of the base frame. The upper part of the support rib plate is flush with the upper surface of the base frame and is welded to the pump bottom plate.

[0023] Furthermore, a gap is left between the lower part of the support rib plate and the bottom of the water tank bottom plate.

[0024] Furthermore, the pump bottom plate is provided with pump installation threaded holes, positioning holes, and O-ring sealing grooves.

[0025] Furthermore, an oil tank bottom plate is welded to the lower plane of the pump bottom plate, and a pump lubricating oil tank is formed between the oil tank bottom plate and the pump body.

[0026] Furthermore, the oil tank bottom plate is provided with an oil drain pipe orifice, and the oil drain pipe is welded to the orifice of the oil tank bottom plate, and the oil drain pipe is lower than the oil tank bottom plate.

[0027] Furthermore, the oil tank drain pipe is welded to the orifice on the outer side of the short end of the base frame, and a valve is provided outside the oil tank drain pipe.

[0028] Furthermore, a water tank upper plate is welded to the base frame, and a motor or reducer support seat and a water injection and liquid collection pipe are welded on the water tank upper plate.

[0029] Furthermore, a water tank bottom plate is welded to the lower plane of the base frame, and a pump cooling water tank is formed between the water tank bottom plate, the horizontal support plate, and the base frame.

[0030] Furthermore, a liquid drain pipe is provided on the outer side of the long end of the base frame of the pump cooling water tank, and a screw plug is provided inside the liquid drain pipe.

[0031] Combined with the above technical solutions and the solved technical problems, the advantages and positive effects of the technical solution to be protected by the present invention are:

[0032] In addition to the conventional functions of supporting pumps, motors or speed reducers, the multi-functional combined base for pumps provided by the present invention newly integrates functions such as a pump oil tank, a pump cooling water tank, pump leakage liquid collection, oil discharge and liquid discharge pipelines, etc., and rationally utilizes the internal space of the pump base bracket to realize the above functions.

[0033] With the help of the cooling water tank of the multi-functional base, the pump unit no longer needs to design and configure a lubricating oil cooling system, which not only simplifies the pipeline of the pump unit and reduces the overall dimensions of the pump unit; moreover, directly cooling the lubricating oil with water is far better than the air-cooling temperature reduction effect, and through the overall base heat dissipation, the temperature rise of the lubricating oil is low, the lubrication effect of the transmission components is good, the product power consumption is small, and the efficiency is high; and it effectively extends the service life of the pump transmission components and improves the product reliability.

[0034] By using the multi-functional base to set up a leakage liquid collection module, not only does the pump unit not need to design and configure a leakage liquid collection system, but also simplifies the pipeline of the pump unit and reduces the overall dimensions.

[0035] The expected benefits and commercial value after the transformation of the technical solution of the present invention are: simplifying the lubricating oil cooling system pipe of the pump unit, reducing the overall dimensions of the pump unit, reducing the weight of the pump unit, realizing product lightweight, reducing the product cost by about 10%; reducing power consumption and improving efficiency; extending the service life of the pump transmission components and enhancing the product reliability.

[0036] The technical solution of the present invention fills the technical gaps at home and abroad in the industry: at present, there is no relevant technical report on setting a lubricating oil tank, a cooling water tank and a leakage liquid collection module in the pump base.
