Center high-pressure water-supplying car washing device

Abstract

The invention belongs to the technical field of car washing machines, and relates to a center high-pressure water-supplying car washing device. The center high-pressure water-supplying car washing device comprises a motor and a high-pressure water pump, wherein the motor drives the high-pressure water pump; an water outlet of the high-pressure water pump is connected with a main water supply pipe; two or more branch water supply pipes communicate to the main water supply pipe; the outer ends of the branch water supply pipes are connected with hydraulic giants; the water supply capacity of the high-pressure water pump is changed by changing the rotating speed of the motor, so that the condition that when the different numbers of the hydraulic giants are opened, the water yield of each of the hydraulic giants meets the design requirements can be adapted. The center high-pressure water-supplying car washing device disclosed by the invention has the advantages that according to the number of the opened hydraulic giant or the closed hydraulic giant, the frequency or water yield of the motor or the water-yield capacity is controlled by a frequency converter, a frequency conversion technique and one motor are adopted for supplying water for the hydraulic giants, so that the equipment is low in comprehensive cost, small in consumed space, low in noise, silent in working environment, and obvious energy-saving effect, and is safe and reliable to operate, convenient to maintain, service and control, and the center high-pressure water-supplying car washing device is suitable for an unit washing cars in a centralized manner.

Description

technical field [0001] The invention belongs to the technical field of car washing machines, in particular to a central high-pressure water supply car washing device. Background technique [0002] At present, there are the following methods for vehicle cleaning: one is to use one motor to drive one water pump, and one water pump provides pressure water for one water gun. If multiple water guns are used to wash the car, multiple sets of motors, water pumps, and water guns are required. The equipment cost is high, and the frequent opening and closing of the motor consumes a lot of energy; the second is that CN203958090U discloses "Safety Car Washing Machine Automatic Opening and Stopping Device and the Car Washing System It Constitutes", including pressure storage tanks, which are respectively arranged at the inlets and outlets at both ends of the pressure storage tanks. The water pipe and the outlet pipe are arranged on the pressure storage tank to provide pressure for the pr...

[0002] At present, there are the following methods for vehicle cleaning: one is to use one motor to drive one water pump, and one water pump provides pressure water for one water gun. If multiple water guns are used to wash the car, multiple sets of motors, water pumps, and water guns are required. The equipment cost is high, and the frequent opening and closing of the motor consumes a lot of energy; the second is that CN203958090U discloses "Safety Car Washing Machine Automatic Opening and Stopping Device and the Car Washing System It Constitutes", including pressure storage tanks, which are respectively arranged at the inlets and outlets at both ends of the pressure storage tanks. The water pipe and the outlet pipe are arranged on the pressure storage tank to provide pressure for the pressure storage tank, the pressure regulating valve of the pressure storage tank, the water flow switch arranged on the water outlet pipe, and the one-way valve arranged on the water inlet pipe, connected with the water flow switch The relay, and the control box connected with the relay, its shortcoming is that setting the pressure storage tank needs to take up a lot of space and funds; the third is that CN202163408U discloses "A Kind of Automatic Central Car Washing Machine", which includes a water supply source, multiple A high-pressure plunger water pump, multiple motors, a pressure tank, a control box and multiple water spray guns; the high-pressure plunger water pump is connected to the water supply source, the motor and the pressure tank respectively, and the pressure tank is connected to multiple water spray guns; Its shortcomings are: the equipment cost of multiple high-pressure water pumps and multiple motors is high, the frequent opening and closing of multiple motors consumes a lot of energy, and the pressure tank needs to occupy a large space and funds
