The invention discloses a dishwasher washing pump and a dishwasher. The dishwasher includes a spray arm. The washing pump includes a pump housing with an inner cavity. In communication, a guide part is provided in the inner cavity of the pump casing, and part of the structure of the guide part is located in the projection of the opening on the inner cavity, and the guide part is used to guide the water flow in the pump casing to change. The direction of movement breaks up the vortex and reduces the local pressure loss of the water flow. The present invention eliminates the energy loss caused by "dead water area" or "vortex area" in the washing pump, thus improving the working efficiency of the washing pump.

The invention belongs to the technical field of fans, and specifically relates to a fan for metal smelting, including a frame, a three-way air duct, a transmission module and an air supply module; a transmission module is installed on the front side of the frame, and the front side of the frame is located Two air supply modules are installed on both sides of the module. The front side of the rack is located above the transmission module and a three-way air duct is installed. There is a motor, and the motor is connected to the transmission module; the transmission module includes a driving wheel, a driven wheel, a double-sided rack and an arc gear; the two ends of the double-sided rack extend to the inside of the two air supply modules; the air supply pipe There are threaded disks, switch units and closed units in sequence in the inside of the air supply pipe; the present invention can use the air supply pipe to discharge the hot air continuously, and the two air supply pipes are alternately transported, which is convenient for the intermittent cooling of the air supply pipe and prolongs the air supply. The service life of the tube is guaranteed to ensure the normal heat transfer operation.

The invention discloses a high-efficiency maintenance device for glazed tile production, which includes a base, a vertically placed slide plate and a fixed plate are arranged above the base, a plurality of insert plates arranged in parallel at equal distances are connected to the side of the slide plate facing the slide plate, and the fixed plate faces the side of the slide plate. There are multiple partitions arranged in parallel at equal distances on the side. There are gaps between adjacent partitions for inserting boards, and there are gaps for inserting boards on the fixed plate. There are a plurality of through grooves, the side of the inserting plate closest to the fixed plate is provided with openings corresponding to the through grooves one by one, the glazed tiles pass through the openings and enter the through grooves, and a plurality of water pipes are arranged on the side of the partition facing the gap, and the water pipes A plurality of small holes are distributed on the side wall facing the inserting board, and all water pipes are connected sequentially from top to bottom, and a slide rail for reciprocating sliding of the sliding board is provided on the top surface of the base along the long side direction. The invention solves the problem that the poor maintenance quality of the glazed tiles will accelerate the breakage of the glazed tiles.

The invention relates to a summer garden water spraying device, in particular to a summer garden self-walking swing water spraying device which can automatically swing and spray water, improve water spraying efficiency and prevent arm aching and clothes wetting. The summer garden self-walking swing water spraying device comprises a mounting plate, supports, a first bearing block, a first rotatingrod, wheels, a bracket, a water tank, a water pump, a hose, a supporting rod, a guide sleeve, a guide rail, a push rod, an arc-shaped sliding rail and the like, wherein the left side and the right side of the mounting plate are connected with the supports. A sprayer can move left and right by the aid of an automatic reciprocating device, so that water can be uniformly sprayed to plants, the firstrotating rod can rotate by the aid of an automatic intermittent walking device and then drive the wheels to rotate, the water spraying device can move as the wheels rotate, manual moving of the waterspraying device is omitted, and labor intensity can be reduced.

A water-saving and environment-friendly agricultural and forestry irrigation device belongs to the field of agricultural and forestry irrigation. A water-saving and environment-friendly agricultural and forestry irrigation device, including a bracket, a first rotating arm and a second rotating arm; the agricultural and forestry irrigation device also includes a sliding sleeve, a supporting rod A, a supporting rod B and a reciprocating sliding sleeve for sliding the sliding sleeve on the bracket. Drive part: a support is fixedly connected to the side wall above the support, a pin shaft is fixedly connected to the support, a cam is fixedly connected to the pin shaft, a water spray cover is connected to the bottom of the first rotating arm, and multiple universal joints are connected to the fixed plate The rubber ball is slidingly connected to the inner wall of the water spray cover with a slide plate, and the bottom of the slide plate is rotatably connected to a plurality of water spray pipes; the first rotating arm and the second rotating arm are equipped with water pipelines; High, so as to change the distance of spraying water. When spraying water at a short distance, the spraying range does not need to be diffused. When spraying at a long distance, multiple spraying pipes are expanded to increase the spraying range and make the spraying more uniform.

The invention discloses a cooling control method and device based on a numerical control machine tool. Wherein, the method includes: determining that the current working state of the cooling module is an automatic mode, wherein the cooling module is used to perform a cooling operation on the tool to be cooled in the CNC machine tool; determining the tool information of the tool to be cooled, and calling the cooling module according to the tool information command; based on the cooling command, the cooling module is controlled to perform a cooling operation on the tool to be cooled. The invention solves the technical problem in the related art that the water spraying control of the numerical control machine tool cannot be automatically adjusted according to the actual demand in the automatic processing process of the numerical control machine tool, resulting in low water spraying efficiency of the numerical control machine tool.
