Problems solved by technology

But it still hasn't solved the problem that the electric water heater can't heat water quantitatively when it is turned on
[0005] The traditional jacket water preheater of diesel engine is heated by steam. The water passes through the jacket water inlet, flows through the water storage pipe, and enters the steam in the water delivery pipe to exchange heat with the flowing water to play the role of heating. However, due to For steam heating, the boiler needs to be turned on in advance to generate steam, which requires a certain amount of preparation time and must be equipped with a steam generator, so it takes up a lot of space and has low efficiency

Embodiment 1

[0019] Such as figure 1 As shown, the jacket water passes through the water inlet pipe 1, passes into the water storage pipe 3, and then flows out through the water outlet pipe 2, and the electric heating pipe 4 is installed on the water storage pipe 3.

[0020] A diesel engine cylinder jacket water preheater, comprising water inlet and outlet pipes, and a water storage pipe 3. After the water inlet pipe 1 passes through the water storage pipe 3, it is connected with the water outlet pipe 2. The water storage pipe 3 is equipped with an electric heating pipe 4 .

[0021] Such as figure 2 As shown, put more than two electric heaters into one shell, and use a partition to divide more than two independent spaces, making it two electric heaters with independent operation functions, thereby further improving the space utilization rate in the cabin .

[0022] The cylinder jacket water preheater for diesel engine of the present invention includes water inlet and outlet pipes and w...

Embodiment 2

[0029] Compared with Embodiment 1, the difference lies in that there are four electric heating pipes 4 installed on the water storage pipe 3 . Other parts are identical with embodiment 1.

Embodiment 3

[0031] Compared with Embodiment 1, the difference lies in that there are six electric heating pipes 4 installed on the water storage pipe 3 . Other parts are identical with embodiment 1.

Abstract

The invention provides a cylinder liner water preheater for a diesel, which comprises water inlets, water outlets, and a water storing pipe, wherein water inlet pipes are communicated with the water storing pipe after passing through the water storing pipe, and a plurality of electric heating tubes are symmetrically mounted on the water storing pipe. The electric heating tubes are electrothermal membrane type or electric heating wire type electric heaters. The cylinder liner water of the diesel can be preheated through the electric heating tubes, so that the defects of large usage space and low efficiency, caused by steam heating, can be avoided. More than two electric heaters are packed into a casing, the casing is divided by baffle plates into more than two independent spaces, and accordingly, the space utilization ratio inside a cabin is further improved.

Description

technical field [0001] The invention relates to a preheater, specifically a diesel engine cylinder jacket water preheater, which includes water inlet and outlet pipes and a water storage pipe. The water inlet pipe is connected with the water outlet pipe after passing through the water storage pipe. Background technique [0002] Water heaters can be divided into three types: electric water heaters, gas water heaters, and solar water heaters according to different principles. Electric water heaters are divided into storage type and instantaneous type, also known as fast electric water heaters. Electric water heaters are characterized by easy use, energy saving and environmental protection, and continuous supply of hot water. Classification of gas water heaters: according to the type of gas used: artificial gas water heaters, natural gas water heaters, liquefied petroleum gas water heaters; according to the control method can be divided into: front-standard water heaters and re...
